First of all, Applets are designed to be run from within the context of a browser (or applet viewer), they're not really designed to be added into other containers.

Technically, you can add a applet to a frame like any other component, but personally, I wouldn't. The applet is expecting a lot more information to be available to it in order to allow it to work fully.

Instead, I would move all of the "application" content to a separate component, like a JPanel for example and simply move this between the applet or frame as required...

ps- You can use f.setLocationRelativeTo(null) to center the window on the screen ;)

Updated

You need to go back to basics. Unless you absolutely must have one, avoid applets until you understand the basics of Swing, case in point...

Within the constructor of GalzyTable2 you are doing...

JApplet app = new JApplet(); add(app); app.init(); app.start(); 

...Why are you adding another applet to an applet??

Case in point...

Within the main method, you are trying to add the instance of JFrame to itself...

f.getContentPane().add(f, button2); 

Instead, create yourself a class that extends from something like JPanel, add your UI logical to this, using compound components if required.

Then, add this panel to whatever top level container you need.

You also seem to have a lack of understanding about how to use layout managers.

Although I've tried all the previous answers, only the following one worked out:

Apart from an understanding of the accesses amongst modules and their respective packages. I believe the crux of it lies in the Module System#Relaxed-strong-encapsulation and I would just cherry-pick the relevant parts of it to try and answer the question.

What defines an illegal reflective access and what circumstances trigger the warning?

To aid in the migration to Java-9, the strong encapsulation of the modules could be relaxed.

• An implementation may provide static access, i.e. by compiled bytecode.

• May provide a means to invoke its run-time system with one or more packages of one or more of its modules open to code in all unnamed modules, i.e. to code on the classpath. If the run-time system is invoked in this way, and if by doing so some invocations of the reflection APIs succeed where otherwise they would have failed.

In such cases, you've actually ended up making a reflective access which is "illegal" since in a pure modular world you were not meant to do such accesses.

How it all hangs together and what triggers the warning in what scenario?

This relaxation of the encapsulation is controlled at runtime by a new launcher option --illegal-access which by default in Java9 equals permit. The permit mode ensures

The first reflective-access operation to any such package causes a warning to be issued, but no warnings are issued after that point. This single warning describes how to enable further warnings. This warning cannot be suppressed.

The modes are configurable with values debug(message as well as stacktrace for every such access), warn(message for each such access), and deny(disables such operations).

Few things to debug and fix on applications would be:-

• Run it with --illegal-access=deny to get to know about and avoid opening packages from one module to another without a module declaration including such a directive(opens) or explicit use of --add-opens VM arg.
• Static references from compiled code to JDK-internal APIs could be identified using the jdeps tool with the --jdk-internals option

The warning message issued when an illegal reflective-access operation is detected has the following form:

WARNING: Illegal reflective access by $PERPETRATOR to $VICTIM

where:

$PERPETRATOR is the fully-qualified name of the type containing the code that invoked the reflective operation in question plus the code source (i.e., JAR-file path), if available, and

$VICTIM is a string that describes the member being accessed, including the fully-qualified name of the enclosing type

Questions for such a sample warning: = JDK9: An illegal reflective access operation has occurred. org.python.core.PySystemState

Last and an important note, while trying to ensure that you do not face such warnings and are future safe, all you need to do is ensure your modules are not making those illegal reflective accesses. :)

As of 30Jul, 2018 to fix the above issue, one can configure the java version used within maven to any up to JDK/11 and make use of the maven-compiler-plugin:3.8.0 to specify a release of either 9,10,11 without any explicit dependencies.

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.8.0</version>
    <configuration>
        <release>11</release>  <!--or <release>10</release>-->
    </configuration>
</plugin>

Note:- The default value for source/target has been lifted from 1.5 to 1.6 with this version. -- release notes.

Edit [30.12.2018]

In fact, you can make use of the same version of maven-compiler-plugin while compiling the code against JDK/12 as well.

More details and a sample configuration in how to Compile and execute a JDK preview feature with Maven.

Configure Two DataSources in Spring Boot 2.0.* or above

If you need to configure multiple data sources, you have to mark one of the DataSource instances as @Primary, because various auto-configurations down the road expect to be able to get one by type.

If you create your own DataSource, the auto-configuration backs off. In the following example, we provide the exact same feature set as the auto-configuration provides on the primary data source:

@Bean
@Primary
@ConfigurationProperties("app.datasource.first")
public DataSourceProperties firstDataSourceProperties() {
    return new DataSourceProperties();
}

@Bean
@Primary
@ConfigurationProperties("app.datasource.first")
public DataSource firstDataSource() {
    return firstDataSourceProperties().initializeDataSourceBuilder().build();
}

@Bean
@ConfigurationProperties("app.datasource.second")
public BasicDataSource secondDataSource() {
    return DataSourceBuilder.create().type(BasicDataSource.class).build();
}

firstDataSourceProperties has to be flagged as @Primary so that the database initializer feature uses your copy (if you use the initializer).

And your application.propoerties will look something like this:

app.datasource.first.url=jdbc:oracle:thin:@localhost/first
app.datasource.first.username=dbuser
app.datasource.first.password=dbpass
app.datasource.first.driver-class-name=oracle.jdbc.OracleDriver

app.datasource.second.url=jdbc:mariadb://localhost:3306/springboot_mariadb
app.datasource.second.username=dbuser
app.datasource.second.password=dbpass
app.datasource.second.driver-class-name=org.mariadb.jdbc.Driver

The above method is the correct to way to init multiple database in spring boot 2.0 migration and above. More read can be found here.

In fact, it's a good habit to check your settings before you run the app.

1. Have you check the java SDK path ?(in fact, if you have already run another app but failed to run this, which might be download from Github or others.
2. then you might have to check the flutter settings and the dart settings.

in the manifest file set second activity parentActivityName as first activity and remove the screenOrientation parameter to the second activity. it means your first activity is the parent and decide to an orientation of your second activity.

<activity
        android:name=".view.FirstActiviy"
        android:screenOrientation="portrait"
        android:theme="@style/AppTheme" />

<activity
        android:name=".view.SecondActivity"
        android:parentActivityName=".view.FirstActiviy"
        android:theme="@style/AppTheme.Transparent" />

From the firebase release notes, they state that support for Android O was first released in 10.2.1 (although I'd recommend using the most recent version).

please add new firebase messaging dependencies for android O

compile 'com.google.firebase:firebase-messaging:11.6.2'

upgrade google play services and google repositories if needed.

Use [ngClass] and conditionally apply class based on the id.

In your HTML file:

<li>
    <img [ngClass]="{'this-is-a-class': id === 1 }" id="1"  
         src="../../assets/images/1.jpg" (click)="addClass(id=1)"/>
</li>
<li>
    <img [ngClass]="{'this-is-a-class': id === 2 }" id="2"  
         src="../../assets/images/2.png" (click)="addClass(id=2)"/>
</li>

In your TypeScript file:

addClass(id: any) {
    this.id = id;
}

use ResponseEntity<ResponseBean>

Here you can use ResponseBean or Any java bean as you like to return your api response and it is the best practice. I have used Enum for response. it will return status code and status message of API.

@GetMapping(path = "/login")
public ResponseEntity<ServiceStatus> restApiExample(HttpServletRequest request,
            HttpServletResponse response) {
        String username = request.getParameter("username");
        String password = request.getParameter("password");

        loginService.login(username, password, request);
        return new ResponseEntity<ServiceStatus>(ServiceStatus.LOGIN_SUCCESS,
                HttpStatus.ACCEPTED);
    }

for response ServiceStatus or(ResponseBody)

    public enum ServiceStatus {

    LOGIN_SUCCESS(0, "Login success"),

    private final int id;
    private final String message;

    //Enum constructor
    ServiceStatus(int id, String message) {
        this.id = id;
        this.message = message;
    }

    public int getId() {
        return id;
    }

    public String getMessage() {
        return message;
    }
}

Spring REST API should have below key in response

1. Status Code
2. Message

you will get final response below

{

   "StatusCode" : "0",

   "Message":"Login success"

}

you can use ResponseBody(java POJO, ENUM,etc..) as per your requirement.

You can also convert the URI to file and then to bytes if you want to upload the photo to your server.

Database access on main thread locking the UI is the error, like Dale said.

--EDIT 2--

Since many people may come across this answer... The best option nowadays, generally speaking, is Kotlin Coroutines. Room now supports it directly (currently in beta). https://kotlinlang.org/docs/reference/coroutines-overview.html https://developer.android.com/jetpack/androidx/releases/room#2.1.0-beta01

--EDIT 1--

For people wondering... You have other options. I recommend taking a look into the new ViewModel and LiveData components. LiveData works great with Room. https://developer.android.com/topic/libraries/architecture/livedata.html

Another option is the RxJava/RxAndroid. More powerful but more complex than LiveData. https://github.com/ReactiveX/RxJava

--Original answer--

Create a static nested class (to prevent memory leak) in your Activity extending AsyncTask.

private static class AgentAsyncTask extends AsyncTask<Void, Void, Integer> {

    //Prevent leak
    private WeakReference<Activity> weakActivity;
    private String email;
    private String phone;
    private String license;

    public AgentAsyncTask(Activity activity, String email, String phone, String license) {
        weakActivity = new WeakReference<>(activity);
        this.email = email;
        this.phone = phone;
        this.license = license;
    }

    @Override
    protected Integer doInBackground(Void... params) {
        AgentDao agentDao = MyApp.DatabaseSetup.getDatabase().agentDao();
        return agentDao.agentsCount(email, phone, license);
    }

    @Override
    protected void onPostExecute(Integer agentsCount) {
        Activity activity = weakActivity.get();
        if(activity == null) {
            return;
        }

        if (agentsCount > 0) {
            //2: If it already exists then prompt user
            Toast.makeText(activity, "Agent already exists!", Toast.LENGTH_LONG).show();
        } else {
            Toast.makeText(activity, "Agent does not exist! Hurray :)", Toast.LENGTH_LONG).show();
            activity.onBackPressed();
        }
    }
}

Or you can create a final class on its own file.

Then execute it in the signUpAction(View view) method:

new AgentAsyncTask(this, email, phone, license).execute();

In some cases you might also want to hold a reference to the AgentAsyncTask in your activity so you can cancel it when the Activity is destroyed. But you would have to interrupt any transactions yourself.

Also, your question about the Google's test example... They state in that web page:

The recommended approach for testing your database implementation is writing a JUnit test that runs on an Android device. Because these tests don't require creating an activity, they should be faster to execute than your UI tests.

No Activity, no UI.

Jersey 2.26 and newer are not backward compatible with older versions. The reason behind that has been stated in the release notes:

Unfortunately, there was a need to make backwards incompatible changes in 2.26. Concretely jersey-proprietary reactive client API is completely gone and cannot be supported any longer - it conflicts with what was introduced in JAX-RS 2.1 (that's the price for Jersey being "spec playground..").

Another bigger change in Jersey code is attempt to make Jersey core independent of any specific injection framework. As you might now, Jersey 2.x is (was!) pretty tightly dependent on HK2, which sometimes causes issues (esp. when running on other injection containers. Jersey now defines it's own injection facade, which, when implemented properly, replaces all internal Jersey injection.

As for now one should use the following dependencies:

Maven

<dependency>
    <groupId>org.glassfish.jersey.inject</groupId>
    <artifactId>jersey-hk2</artifactId>
    <version>2.26</version>
</dependency>

Gradle

compile 'org.glassfish.jersey.core:jersey-common:2.26'
compile 'org.glassfish.jersey.inject:jersey-hk2:2.26'

I you want to put the response of the request in the navItems. Because http.get() return an observable you will have to subscribe to it.

Look at this example:

// version without map_x000D_
this.http.get("../data/navItems.json")_x000D_
    .subscribe((success) => {_x000D_
      this.navItems = success.json();          _x000D_
    });_x000D_
_x000D_
// with map_x000D_
import 'rxjs/add/operator/map'_x000D_
this.http.get("../data/navItems.json")_x000D_
    .map((data) => {_x000D_
      return data.json();_x000D_
    })_x000D_
    .subscribe((success) => {_x000D_
      this.navItems = success;          _x000D_
    });

If you are running on a linux environment, basically your app does not have rights for the default port.

Try 8181 by giving the following option on VM.

-Dserver.port=8181

Changing this project setting solve the issue for me.

I am sure I am late to the party but below worked for me.

<paths>
    <root-path name="root" path="." />
</paths>

In my case I had to clear browser history/cookies to get rid of this error.

The URI is encoded as UTF-8, but Tomcat is decoding them as ISO-8859-1. You need to edit the connector settings in the server.xml and add the URIEncoding="UTF-8" attribute.

or edit this parameter on your application.properties

server.tomcat.uri-encoding=utf-8

It's now called rounded-circle as explained here in the BS4 docs

<img src="img/gallery2.JPG" class="rounded-circle">

Demo

changing

classpath 'com.google.gms:google-services:4.1.0'

to

classpath 'com.google.gms:google-services:4.0.1'

Works for me

When all the classes were in same package, test classes were working. As soon as I moved all the java classes to different package to maintain proper project structure I was getting the same error.

I solved it by providing my main class name in the test class like below.

@SpringBootTest(classes=JunitBasicsApplication.class)

Every Driver service in selenium calls the similar code(following is the firefox specific code) while creating the driver object

 @Override
 protected File findDefaultExecutable() {
      return findExecutable(
        "geckodriver", GECKO_DRIVER_EXE_PROPERTY,
        "https://github.com/mozilla/geckodriver",
        "https://github.com/mozilla/geckodriver/releases");
    }

now for the driver that you want to use, you have to set the system property with the value of path to the driver executable.

for firefox GECKO_DRIVER_EXE_PROPERTY = "webdriver.gecko.driver" and this can be set before creating the driver object as below

System.setProperty("webdriver.gecko.driver", "./libs/geckodriver.exe");
WebDriver driver = new FirefoxDriver();

Happened to me because I used

PropTypes.arrayOf(SomeClass)

instead of

PropTypes.arrayOf(PropTypes.instanceOf(SomeClass))

A solution I came up with is to use a vis.js instance in an iframe. This shows an interactive 3D plot inside a notebook, which still works in nbviewer. The visjs code is borrowed from the example code on the 3D graph page

A small notebook to illustrate this: demo

The code itself:

        "showGrid": True,
        "showShadow": False,
        "keepAspectRatio": True,
        "height": str(height) + "px"
    }

    if initialCamera:
        options["cameraPosition"] = initialCamera

    data = [ {"x": X[y,x], "y": Y[y,x], "z": Z[y,x]} for y in range(X.shape[0]) for x in range(X.shape[1]) ]

I saw the same error when the scope of the jackson-databind dependency had been set to test:

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.9.9</version>
    <scope>test</scope>
</dependency>

Removing the <scope> line fixed the issue.

your manifest application name should contain application class name. Like

<application
        android:name="your package name.MyApplication"
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:largeHeap="true"
        android:theme="@style/AppTheme"> 

I know this is extremely late to the game, but I wanted to post the additional issue I faced when using mysql, if anyone faces the same issue in future.

As some of the answers mentioned above, setting these in the application.properties will mostly fix the problem

spring.http.multipart.max-file-size=16MB
spring.http.multipart.max-request-size=16MB

I am setting it to 16 MB, because I am using mysql MEDIUMBLOB datatype to store the file.

But after fixing the application.properties, When uploading a file > 4MB gave the error: org.springframework.dao.TransientDataAccessResourceException: PreparedStatementCallback; SQL [insert into test_doc(doc_id, duration_of_doc, doc_version_id, file_name, doc) values (?, ?, ?, ?, ?)]; Packet for query is too large (6656781 > 4194304). You can change this value on the server by setting the max_allowed_packet' variable.; nested exception is com.mysql.jdbc.PacketTooBigException: Packet for query is too large (6656781 > 4194304). You can change this value on the server by setting the max_allowed_packet' variable.

So I ran this command from mysql:

SET GLOBAL max_allowed_packet = 1024*1024*16;

I had the same issue and fixed by using project level crashlytics gradle version 2.1.1

classpath 'com.google.firebase:firebase-crashlytics-gradle:2.1.1'

Go to Phone Settings --> Developer Options --> Simulate Secondary Displays and turn it to None. If you don't see Developer Options in the settings menu (it should be at the bottom, go Settings ==> About phone and tap on the Build number a lot of times)

I was facing the same issue where my current branch was dev and I was checking out to MR branch and doing git pull thereafter. An easy workaround that I took was I created a new folder for MR Branch and did git pull there followed by git clone.

So basically I maintained different folders for pushing code to different branch.

Your test requires a ServletContext: add @WebIntegrationTest

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = AppConfig.class, loader = AnnotationConfigContextLoader.class)
@WebIntegrationTest
public class UserServiceImplIT

...or look here for other options: https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-testing.html

UPDATE In Spring Boot 1.4.x and above @WebIntegrationTest is no longer preferred. @SpringBootTest or @WebMvcTest

Before Android 4.4

What you are trying to do is simply not possible from an app (at least not on a non-rooted/non-modified device). The message "NFC tag type not supported" is displayed by the Android system (or more specifically the NFC system service) before and instead of dispatching the tag to your app. This means that the NFC system service filters MIFARE Classic tags and never notifies any app about them. Consequently, your app can't detect MIFARE Classic tags or circumvent that popup message.

On a rooted device, you may be able to bypass the message using either

1. Xposed to modify the behavior of the NFC service, or

2. the CSC (Consumer Software Customization) feature configuration files on the system partition (see /system/csc/. The NFC system service disables the popup and dispatches MIFARE Classic tags to apps if the CSC feature <CscFeature_NFC_EnableSecurityPromptPopup> is set to any value but "mifareclassic" or "all". For instance, you could use:

   <CscFeature_NFC_EnableSecurityPromptPopup>NONE</CscFeature_NFC_EnableSecurityPromptPopup>
   

   You could add this entry to, for instance, the file "/system/csc/others.xml" (within the section <FeatureSet> ... </FeatureSet> that already exists in that file).

Since, you asked for the Galaxy S6 (the question that you linked) as well: I have tested this method on the S4 when it came out. I have not verified if this still works in the latest firmware or on other devices (e.g. the S6).

Since Android 4.4

This is pure guessing, but according to this (link no longer available), it seems that some apps (e.g. NXP TagInfo) are capable of detecting MIFARE Classic tags on affected Samsung devices since Android 4.4. This might mean that foreground apps are capable of bypassing that popup using the reader-mode API (see NfcAdapter.enableReaderMode) possibly in combination with NfcAdapter.FLAG_READER_SKIP_NDEF_CHECK.

In my case these steps solved my problem:

1. terminating npm process (CTRL + C)
2. deleting entire folder
3. creating new one
4. running npm again

It happens because Build Tools revision 24.4.1 doesn't exist.

The latest version is 23.0.2.
These tools is included in the SDK package and installed in the <sdk>/build-tools/ directory.

Don't confuse the Android SDK Tools with SDK Build Tools.

Change in your build.gradle

android {
   buildToolsVersion "23.0.2"
   // ...

}

A simple answer if you don't want to install anything new

To change all the fonts in your plot plot + theme(text=element_text(family="mono")) Where mono is your chosen font.

List of default font options:

• mono
• sans
• serif
• Courier
• Helvetica
• Times
• AvantGarde
• Bookman
• Helvetica-Narrow
• NewCenturySchoolbook
• Palatino
• URWGothic
• URWBookman
• NimbusMon
• URWHelvetica
• NimbusSan
• NimbusSanCond
• CenturySch
• URWPalladio
• URWTimes
• NimbusRom

R doesn't have great font coverage and, as Mike Wise points out, R uses different names for common fonts.

This page goes through the default fonts in detail.

@PostMapping(path = "/my/endpoint", consumes = { MediaType.APPLICATION_FORM_URLENCODED_VALUE })
public ResponseEntity<Void> handleBrowserSubmissions(MyDTO dto) throws Exception {
    ...
}

That way works for me

   FirebaseAuth firebaseauth = FirebaseAuth.getInstance(); 

   NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);   //displays text of header of nav drawer.
    View headerview = navigationView.getHeaderView(0);

    TextView tt1 = (TextView) headerview.findViewById(R.id.textview_username);
    tt1.setText(firebaseauth.getCurrentUser().getDisplayName());//username of logged in user.  

   TextView tt = (TextView) headerview.findViewById(R.id.textView_emailid);
    tt.setText(firebaseauth.getCurrentUser().getEmail());    //email id of logged in user.

    final ImageView img1 = (ImageView) headerview.findViewById(R.id.imageView_userimage);
    Glide.with(getApplicationContext())
            .load(firebaseauth.getCurrentUser().getPhotoUrl()).asBitmap().atMost().error(R.drawable.ic_selfie_point_icon)   //asbitmap after load always.
            .into(new SimpleTarget<Bitmap>() {
                @Override
                public void onResourceReady(Bitmap resource, GlideAnimation<? super Bitmap> glideAnimation) {
                    img1.setImageBitmap(resource);
                }
            });

I have made this code by myself with some logic...Its 100% working.....pls do upvote my ans.

The textview and imageview are from @layout/nav_header_main.xml

When I was facing this issue, I simply put just getter setter methods and my issues were resolved.

I am using Spring boot version 2.0.

I had the same its because of version incompatibility check for version or remove version if using spring boot

** Update ** A scalars converter has been added to retrofit that allows for a String response with less ceremony than my original answer below.

Example interface --

public interface GitHubService {
    @GET("/users/{user}")
    Call<String> listRepos(@Path("user") String user);
}

Add the ScalarsConverterFactory to your retrofit builder. Note: If using ScalarsConverterFactory and another factory, add the scalars factory first.

Retrofit retrofit = new Retrofit.Builder()
    .baseUrl(BASE_URL)
    .addConverterFactory(ScalarsConverterFactory.create())
    // add other factories here, if needed.
    .build();

You will also need to include the scalars converter in your gradle file --

implementation 'com.squareup.retrofit2:converter-scalars:2.1.0'

--- Original Answer (still works, just more code) ---

I agree with @CommonsWare that it seems a bit odd that you want to intercept the request to process the JSON yourself. Most of the time the POJO has all the data you need, so no need to mess around in JSONObject land. I suspect your specific problem might be better solved using a custom gson TypeAdapter or a retrofit Converter if you need to manipulate the JSON. However, retrofit provides more the just JSON parsing via Gson. It also manages a lot of the other tedious tasks involved in REST requests. Just because you don't want to use one of the features, doesn't mean you have to throw the whole thing out. There are times you just want to get the raw stream, so here is how to do it -

First, if you are using Retrofit 2, you should start using the Call API. Instead of sending an object to convert as the type parameter, use ResponseBody from okhttp --

public interface GitHubService {
    @GET("/users/{user}")
    Call<ResponseBody> listRepos(@Path("user") String user);
}

then you can create and execute your call --

GitHubService service = retrofit.create(GitHubService.class);
Call<ResponseBody> result = service.listRepos(username);
result.enqueue(new Callback<ResponseBody>() {
    @Override
    public void onResponse(Response<ResponseBody> response) {
        try {
            System.out.println(response.body().string());
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    @Override
    public void onFailure(Throwable t) {
        e.printStackTrace();
    }
});

Note The code above calls string() on the response object, which reads the entire response into a String. If you are passing the body off to something that can ingest streams, you can call charStream() instead. See the ResponseBody docs.

The reason must be somewhere else. Using only Spring Boot 1.2.2 out of the box with no configuration, it Just Works. Have a look at this repo - can you get it to break?

https://github.com/konrad-garus/so-yaml

Are you sure the YAML file looks exactly the way you pasted? No extra whitespace, characters, special characters, mis-indentation or something of that sort? Is it possible you have another file elsewhere in the search path that is used instead of the one you're expecting?

Please Check below code that using that You can find all Music Files from sdcard :

public class MainActivity extends Activity{

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_animations);
    getAllSongsFromSDCARD();

}

public void getAllSongsFromSDCARD() {
    String[] STAR = { "*" };
    Cursor cursor;
    Uri allsongsuri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
    String selection = MediaStore.Audio.Media.IS_MUSIC + " != 0";

    cursor = managedQuery(allsongsuri, STAR, selection, null, null);

    if (cursor != null) {
        if (cursor.moveToFirst()) {
            do {
                String song_name = cursor
                        .getString(cursor
                                .getColumnIndex(MediaStore.Audio.Media.DISPLAY_NAME));
                int song_id = cursor.getInt(cursor
                        .getColumnIndex(MediaStore.Audio.Media._ID));

                String fullpath = cursor.getString(cursor
                        .getColumnIndex(MediaStore.Audio.Media.DATA));

                String album_name = cursor.getString(cursor
                        .getColumnIndex(MediaStore.Audio.Media.ALBUM));
                int album_id = cursor.getInt(cursor
                        .getColumnIndex(MediaStore.Audio.Media.ALBUM_ID));

                String artist_name = cursor.getString(cursor
                        .getColumnIndex(MediaStore.Audio.Media.ARTIST));
                int artist_id = cursor.getInt(cursor
                        .getColumnIndex(MediaStore.Audio.Media.ARTIST_ID));
                System.out.println("sonng name"+fullpath);
            } while (cursor.moveToNext());

        }
        cursor.close();
    }
}


}

I have also added following line in the AndroidManifest.xml file as below:

<uses-sdk
    android:minSdkVersion="16"
    android:targetSdkVersion="17" />

<uses-permission android:name="android.permission.MEDIA_CONTENT_CONTROL" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

The REST API of Instagram has been discontinued. But you can use GraphQL to get the desired data. Here you can find an overview: https://developers.facebook.com/docs/instagram-api

This is possible using the mergeFunction parameter of Collectors.toMap(keyMapper, valueMapper, mergeFunction):

Map<String, String> phoneBook = 
    people.stream()
          .collect(Collectors.toMap(
             Person::getName,
             Person::getAddress,
             (address1, address2) -> {
                 System.out.println("duplicate key found!");
                 return address1;
             }
          ));

mergeFunction is a function that operates on two values associated with the same key. adress1 corresponds to the first address that was encountered when collecting elements and adress2 corresponds to the second address encountered: this lambda just tells to keep the first address and ignores the second.

Sure you can:

https://<organization>.slack.com/messages/<channel>/

for example: https://tikal.slack.com/messages/general/ (of course that for accessing it, you must be part of the team)

I finally was able to figure out a simple solution without the @Query annotation.

List<People> findDistinctByNameNotIn(List<String> names);

Of course, I got the people object instead of only Strings. I can then do the change in java.

It seems that ARM64 was created by Apple and AARCH64 by the others, most notably GNU/GCC guys.

After some googling I found this link:

The LLVM 64-bit ARM64/AArch64 Back-Ends Have Merged

So it makes sense, iPad calls itself ARM64, as Apple is using LLVM, and Edge uses AARCH64, as Android is using GNU GCC toolchain.

This can happen if you have a newline (or other control character) in a JSON string literal.

{"foo": "bar
baz"}

If you are the one producing the data, replace actual newlines with escaped ones "\\n" when creating your string literals.

{"foo": "bar\nbaz"}

This is valid YAML:

jobs:
 - name: A
   schedule: "0 0/5 * 1/1 * ? *"
   type: mongodb.cluster
   config:
     host: mongodb://localhost:27017/admin?replicaSet=rs
     minSecondaries: 2
     minOplogHours: 100
     maxSecondaryDelay: 120
 - name: B
   schedule: "0 0/5 * 1/1 * ? *"
   type: mongodb.cluster
   config:
     host: mongodb://localhost:27017/admin?replicaSet=rs
     minSecondaries: 2
     minOplogHours: 100
     maxSecondaryDelay: 120

Note, that every '-' starts new element in the sequence. Also, indentation of keys in the map should be exactly same.

Since seaborn also uses matplotlib to do its plotting you can easily combine the two. If you only want to adopt the styling of seaborn the set_style function should get you started:

import matplotlib.pyplot as plt
import numpy as np
import seaborn as sns

sns.set_style("darkgrid")
plt.plot(np.cumsum(np.random.randn(1000,1)))
plt.show()

Result:

Try upgrade your Android SDK Platform as below steps:

1. Run the SDK Manager

2. Execute "Install packages…"

3. Restart the SDK Manager

I tried and it's ok for me.

ref: link

Notifications are greyscale as explained below. They are not black-and-white, despite what others have written. You have probably seen icons with multiple shades, like network strength bars.

Prior to API 21 (Lollipop 5.0), colour icons work. You could force your application to target API 20, but that limits the features available to your application, so it is not recommended. You could test the running API level and set either a colour icon or a greyscale icon appropriately, but this is likely not worthwhile. In most cases, it is best to go with a greyscale icon.

Images have four channels, RGBA (red / green / blue / alpha). For notification icons, Android ignores the R, G, and B channels. The only channel that counts is Alpha, also known as opacity. Design your icon with an editor that gives you control over the Alpha value of your drawing colours.

How Alpha values generate a greyscale image:

• Alpha = 0 (transparent) — These pixels are transparent, showing the background colour.
• Alpha = 255 (opaque) — These pixels are white.
• Alpha = 1 ... 254 — These pixels are exactly what you would expect, providing the shades between transparent and white.

Changing it up with setColor:

• Call NotificationCompat.Builder.setColor(int argb). From the documentation for Notification.color:

  Accent color (an ARGB integer like the constants in Color) to be applied by the standard Style templates when presenting this notification. The current template design constructs a colorful header image by overlaying the icon image (stenciled in white) atop a field of this color. Alpha components are ignored.

  My testing with setColor shows that Alpha components are not ignored. Higher Alpha values turn a pixel white. Lower Alpha values turn a pixel to the background colour (black on my device) in the notification area, or to the specified colour in the pull-down notification.

I had a simple code for Spring Cloud Config

like this:

In application.properties

spring.data.mongodb.db1=mongodb://[email protected]

spring.data.mongodb.db2=mongodb://[email protected]

read

@Bean(name = "mongoConfig")
@ConfigurationProperties(prefix = "spring.data.mongodb")
public Map<String, Map<String, String>> mongoConfig() {
    return new HashMap();
}

use

@Autowired
@Qualifier(value = "mongoConfig")
private Map<String, String> mongoConfig;

@Bean(name = "mongoTemplates")
public HashMap<String, MongoTemplate> mongoTemplateMap() throws UnknownHostException {
    HashMap<String, MongoTemplate> mongoTemplates = new HashMap<>();
    for (Map.Entry<String, String>> entry : mongoConfig.entrySet()) {
        String k = entry.getKey();
        String v = entry.getValue();
        MongoTemplate template = new MongoTemplate(new SimpleMongoDbFactory(new MongoClientURI(v)));
        mongoTemplates.put(k, template);
    }
    return mongoTemplates;
}

I got the same issue and after a lot of time spent on the search I found the solution

Just change your method especially // DownloadsProvider part

getpath()

to

You can get hostname from spring cloud property in spring-cloud-commons-2.1.0.RC2.jar

environment.getProperty("spring.cloud.client.ip-address");
environment.getProperty("spring.cloud.client.hostname");

spring.factories of spring-cloud-commons-2.1.0.RC2.jar

org.springframework.boot.env.EnvironmentPostProcessor=\
org.springframework.cloud.client.HostInfoEnvironmentPostProcessor

Although you can have logat on a real device too, if you need to use an emulator try transferring the images through the Android Device Monitor, accessible from the toolbar in Android Studio (it's in eclipse too, of course).

Once you select the device from ADM, you can see the folders tree and copy things inside

I tested and used this command in kafka confluent V4.0.0 and apache kafka V 1.0.0 and 1.0.1

/opt/kafka/confluent-4.0.0/bin/kafka-configs --zookeeper XX.XX.XX.XX:2181 --entity-type topics --entity-name test --alter --add-config  retention.ms=55000

test is the topic name.

I think it works well in other versions too

If you have USB-Debugging/ADB enabled on your phone and your PC is authorized for debugging on your phone then you can try one of the follwing tools:

scrcpy

scrcpy connects over adb to your device and executes a temporary app to stream the contents of your screen to your PC and you're able to remote control your device. It works on GNU/Linux, Windows and macOS.

Vysor

Vysor is a chrome web app that connects to your device via adb and installs a companion app to stream your screen content to the PC. You can then remote control your device with your mouse.

MonkeyRemote

MonkeyRemote is a remote control tool written by myself before I found Vysor. It also connects through adb and lets you control your device by mouse but in contrast to Vysor, the streamed screen content updates very slow (~1 frame per second). The upside is that there is no need for a companion app to be installed.

The solution for the issue:

public class yourRecyclerViewAdapter extends RecyclerView.Adapter<yourRecyclerViewAdapter.yourViewHolder> {

private static CheckBox lastChecked = null;
private static int lastCheckedPos = 0;


public void onBindViewHolder(ViewHolder holder, final int position) {

    holder.mTextView.setText(fonts.get(position).getName());
    holder.checkBox.setChecked(fonts.get(position).isSelected());
    holder.checkBox.setTag(new Integer(position));

    //for default check in first item
    if(position == 0 && fonts.get(0).isSelected() && holder.checkBox.isChecked())
    {
       lastChecked = holder.checkBox;
       lastCheckedPos = 0;
    }

    holder.checkBox.setOnClickListener(new View.OnClickListener() 
    {
        @Override
        public void onClick(View v) 
        {
           CheckBox cb = (CheckBox)v;
           int clickedPos = ((Integer)cb.getTag()).intValue(); 

           if(cb.isChecked())
           {
              if(lastChecked != null)
              {
                  lastChecked.setChecked(false);
                  fonts.get(lastCheckedPos).setSelected(false);
              }                       

              lastChecked = cb;
              lastCheckedPos = clickedPos;

Hope this help!

Sometimes this exception is caused by a bug in the support library implementation. Recently I had to downgrade from 26.1.0 to 25.4.0 to get rid of it.

Faced similar issue. In my case the repository and the type being managed where not in same package.

Your encoded text is [B@6499375d. That is not Base64, something went wrong while encoding. That decoding code looks good.

Use this code to convert the byte[] to a String before adding it to the URL:

String encodedEmailString = new String(encodedEmail, "UTF-8");
// ...
String confirmLink = "Complete your registration by clicking on following"
    + "\n<a href='" + confirmationURL + encodedEmailString + "'>link</a>";

You forgot @Service annotation in your service class.

The so-called "Rosetta Flash" vulnerability is that allowing arbitrary yet identifier-like text at the beginning of a JSONP response is sufficient for it to be interpreted as a Flash file executing in that origin. See for more information: http://miki.it/blog/2014/7/8/abusing-jsonp-with-rosetta-flash/

JSONP responses from the proxy servlet now: * are prefixed with "/**/", which still allows them to execute as JSONP but removes requester control over the first bytes of the response. * have the response header Content-Disposition: attachment.

In my case, I am Returning JSON Object as

{"data":"","message":"Attendance Saved Successfully..!!!","status":"success"}

Resolved by changing it as

{"data":{},"message":"Attendance Saved Successfully..!!!","status":"success"}

Here data is a sub JsonObject and it should starts from { not ""

My solution was to add a space between the $ and the {.

For example:

@Value("${appclient.port:}")

becomes

@Value("$ {appclient.port:}")

This link has solution of how to get it working. Removing "pom.xml" from the "Profiles:" line and then click "Run".

If other solution is not working like:

View view = inflater.inflate(R.layout.child_layout_to_merge, parent_layout, false);

check for what are you returning from onCreateView of fragment is it single view or viewgroup? in my case I had viewpager on root of xml of fragment and I was returning viewpager, when i added viewgroup in layout i didnt updated that i have to return viewgroup now, not viewpager(view).

If you're using application.properties in spring boot app, then just put the below line into application.properties and it should work:
spring.datasource.url: jdbc:mysql://google/?cloudSqlInstance=&socketFactory=com.google.cloud.sql.mysql.SocketFactory&user=****&password=****

I used file upload example from,

http://www.mkyong.com/webservices/jax-rs/file-upload-example-in-jersey/

in my resource class i have below method

@POST
    @Path("/upload")
    @Consumes(MediaType.MULTIPART_FORM_DATA)
    public Response  attachupload(@FormDataParam("file") byte[] is,
@FormDataParam("file") FormDataContentDisposition fileDetail,
@FormDataParam("fileName") String flename){
attachService.saveAttachment(flename,is);
}

in my attachService.java i have below method

 public void saveAttachment(String flename,  byte[] is) {
            // TODO Auto-generated method stub
         attachmentDao.saveAttachment(flename,is);

        }

in Dao i have

attach.setData(is);
attach.setFileName(flename);

in my HBM mapping is like

<property name="data" type="binary" >
            <column name="data" />
</property>

This working for all type of files like .PDF,.TXT, .PNG etc.,

If you have Android Studio then it is very very simple. Just create a MapActivity using Android Studio and after creating it go into google_maps_api.xml. In there there will be a link given in comments. If you paste it in your browser, it will ask a few details to be filled in and after that your API will be generated. There is no need of using keytool and all.

Screen shot:

I had the same problem. Restart my android device and closed the adb.exe process. With that I could solve the problem

To resolve this error:

ORA-01653 unable to extend table by 1024 in tablespace your-tablespace-name

Just run this PL/SQL command for extended tablespace size automatically on-demand:

alter database datafile '<your-tablespace-name>.dbf' autoextend on maxsize unlimited;

I get this error in import big dump file, just run this command without stopping import routine or restarting the database.

Note: each data file has a limit of 32GB of size if you need more than 32GB you should add a new data file to your existing tablespace.

More info: alter_autoextend_on

At the beginning of your file you set raw_input to 0. Do not do this, at it modifies the built-in raw_input() function. Therefore, whenever you call raw_input(), it is essentially calling 0(), which raises the error. To remove the error, remove the first line of your code:

You have more static resources that the cache has room for. You can do one of the following:

• Increase the size of the cache
• Decrease the TTL for the cache
• Disable caching

For more details see the documentation for these configuration options.

Well, the only thing I can make it work is like so:

servers: >
    dev.example.com,
    another.example.com

@Value("${servers}")
private String[] array;

And dont forget the @Configuration above your class....

Without the "," separation, no such luck...

Works too (boot 1.5.8 versie)

servers: 
       dev.example.com,
       another.example.com

@Override
public void onClick(View v) {
     int pos = getAdapterPosition();
}

Simple as that, on ViewHolder

You can use the following codes to have a full page in android

Step 1 : Make theme in styles.xml section

<style name="AppTheme.Fullscreen" parent="AppTheme">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
</style>

Step 2 : Add theme on AndroidManifest.xml

<activity
android:name=“.Activity”
android:theme="@style/AppTheme.Fullscreen"/>

Step 3 : Java codes section

For example you can added following codes in to the onCreate() method.

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

I had toolbar added in my xml. Then in my activity i was adding this statement:

setSupportActionBar(toolbar);

Removing this worked for me. I hope it helps someone.

The root cause of IllegalStateException exception is a java servlet is attempting to write to the output stream (response) after the response has been committed.

It is always better to ensure that no content is added to the response after the forward or redirect is done to avoid IllegalStateException. It can be done by including a ‘return’ statement immediately next to the forward or redirect statement.

ADDITIONAL INFO

Delete the folder .android from C:/users/<user name>/.android. It solved the issue for me.

Best guess is you are on windows and your line ending settings are set for windows. See this topic: How to change line-ending settings

or use:

tr '\r\n' ' '

If you just want let the user choose image with UIImagePickerController use this code:

import UIKit


class ViewController: UIViewController, UINavigationControllerDelegate, UIImagePickerControllerDelegate {

    @IBOutlet var imageView: UIImageView!
    @IBOutlet var chooseBuuton: UIButton!
    var imagePicker = UIImagePickerController()

    @IBAction func btnClicked() {

        if UIImagePickerController.isSourceTypeAvailable(.savedPhotosAlbum){
            print("Button capture")

            imagePicker.delegate = self
            imagePicker.sourceType = .savedPhotosAlbum
            imagePicker.allowsEditing = false

            present(imagePicker, animated: true, completion: nil)
        }
    }

    func imagePickerController(picker: UIImagePickerController!, didFinishPickingImage image: UIImage!, editingInfo: NSDictionary!){
        self.dismiss(animated: true, completion: { () -> Void in

        })

        imageView.image = image
    }
}

If you really need to have ADB running as root, the quickest and easiest way is to install Android Custom ROMs and the most popular is CyanogenMod for it has the Root Access options in developer options menu where you can choose to give root access to apps and ADB. I used CM before but since it wasn't developed anymore, I tried looking for some solutions out there. Although CyanogenMod is still a good alternative because it does not have bloatware.

One alternative I found out from a friend is using adbd insecure app which you could try from here: https://forum.xda-developers.com/showthread.php?t=1687590. In my case, it works perferct with an Android custom kernel, but not with the Android stock ROM (vanilla android only). You may try other alternatives too like modifying boot.img of the Android ROM.

You can remove it completely by specifying:

import org.springframework.context.annotation.Configuration;
import org.springframework.boot.autoconfigure.web.servlet.error.ErrorMvcAutoConfiguration;
...
@Configuration
@EnableAutoConfiguration(exclude = {ErrorMvcAutoConfiguration.class})
public static MainApp { ... }

However, do note that doing so will probably cause servlet container's whitelabel pages to show up instead :)

EDIT: Another way to do this is via application.yaml. Just put in the value:

spring:
  autoconfigure:
    exclude: org.springframework.boot.autoconfigure.web.servlet.error.ErrorMvcAutoConfiguration

Documentation

For Spring Boot < 2.0, the class is located in package org.springframework.boot.autoconfigure.web.

I have done numerous ways of handling that issue. Finally it has worked! I am using LG Optimus II, but I believe the following steps are generic to other Android devices as well.

Step 1:

Make sure your device is enabled for development. If yes, go to Step 2, otherwise go to Settings > About phone and tap Build number seven times which is magic number :-). Now Developer Options is available in the Settings.

Step 2:

Before you plug your device to PC, Go to Settings > Developer Options and select USB Connection method.

Step 3:

Plug the phone to the PC, you are given options for the USB Connection method, and please select Internet connection. Make sure you have connected to the Internet. By the way, I have changed MTP to PTP, it did not work for me. Therefore, I tried Internet connection mode, then it worked.

Step 4:

Run the app in the Android Studio, it will ask you to authorize the device for development, and select YES!.

Step 5:

Run the application via Android Studio and choose the device, not emulator, and BINGO! Welcome to Android development board.

An assertion Error is thrown when say "You have written a code that should not execute at all costs because according to you logic it should not happen. BUT if it happens then throw AssertionError. And you don't catch it." In such a case you throw an Assertion error.

new IllegalStateException("Must not instantiate an element of this class")' // Is an Exception not error.

Note: Assertion Error comes under java.lang.Error And Errors not meant to be caught.

I faced the same error and realized that pom.xml had java 1.7 and STS compiler pointed to Java 1.8. Upon changing compiler to 1.7 and rebuild fixed the issue.

PS: This answer is not related to actual question posted but applies to similar error for app Context not loading

Here is a simple solution

try adding this dependency

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.8.3</version>
</dependency>

public static int [] locations={1,2,3};

public static test dot=new test();

Declare the above variables above the main method and the code compiles fine.

public static void main(String[] args){

Per numpy docs:

When operating on two arrays, NumPy compares their shapes element-wise. It starts with the trailing dimensions, and works its way forward. Two dimensions are compatible when:

• they are equal, or
• one of them is 1

In other words, if you are trying to multiply two matrices (in the linear algebra sense) then you want X.dot(y) but if you are trying to broadcast scalars from matrix y onto X then you need to perform X * y.T.

Example:

>>> import numpy as np
>>>
>>> X = np.arange(8).reshape(4, 2)
>>> y = np.arange(2).reshape(1, 2)  # create a 1x2 matrix
>>> X * y
array([[0,1],
       [0,3],
       [0,5],
       [0,7]])

Why don't you use spring's TransactionTemplate to programmatically control transactions? You could also restructure your code so that each "transaction block" has it's own @Transactional method, but given that it's a test I would opt for programmatic control of your transactions.

Also note that the @Transactional annotation on your runnable won't work (unless you are using aspectj) as the runnables aren't managed by spring!

@RunWith(SpringJUnit4ClassRunner.class)
//other spring-test annotations; as your database context is dirty due to the committed transaction you might want to consider using @DirtiesContext
public class TransactionTemplateTest {

@Autowired
PlatformTransactionManager platformTransactionManager;

TransactionTemplate transactionTemplate;

@Before
public void setUp() throws Exception {
    transactionTemplate = new TransactionTemplate(platformTransactionManager);
}

@Test //note that there is no @Transactional configured for the method
public void test() throws InterruptedException {

    final Contract c1 = transactionTemplate.execute(new TransactionCallback<Contract>() {
        @Override
        public Contract doInTransaction(TransactionStatus status) {
            Contract c = contractDOD.getNewTransientContract(15);
            contractRepository.save(c);
            return c;
        }
    });

    ExecutorService executorService = Executors.newFixedThreadPool(5);

    for (int i = 0; i < 5; ++i) {
        executorService.execute(new Runnable() {
            @Override  //note that there is no @Transactional configured for the method
            public void run() {
                transactionTemplate.execute(new TransactionCallback<Object>() {
                    @Override
                    public Object doInTransaction(TransactionStatus status) {
                        // do whatever you want to do with c1
                        return null;
                    }
                });
            }
        });
    }

    executorService.shutdown();
    executorService.awaitTermination(10, TimeUnit.SECONDS);

    transactionTemplate.execute(new TransactionCallback<Object>() {
        @Override
        public Object doInTransaction(TransactionStatus status) {
            // validate test results in transaction
            return null;
        }
    });
}

}

You first have to 'dot' source the script, so for you :

. .\Get-NetworkStatistics.ps1

The first 'dot' asks PowerShell to load the script file into your PowerShell environment, not to start it. You should also use set-ExecutionPolicy Unrestricted or set-ExecutionPolicy AllSigned see(the Execution Policy instructions).

var response = taskwithresponse.Result;
          var jsonString = response.ReadAsAsync<List<Job>>().Result;

I also wanted to clarify that if you have complex url parameters to build, you will need to build them manually. ie if your query is example.com/?latlng=-37,147, instead of providing the lat and lng values individually, you will need to build the latlng string externally, then provide it as a parameter, ie:

public interface LocationService {    
    @GET("/example/")
    void getLocation(@Query(value="latlng", encoded=true) String latlng);
}

Note the encoded=true is necessary, otherwise retrofit will encode the comma in the string parameter. Usage:

String latlng = location.getLatitude() + "," + location.getLongitude();
service.getLocation(latlng);

In case it helps anyone I will post what worked for me.

I had to plug my S3 into a direct USB port of my PC for it to prompt me to accept the RSA signature. I had my S3 plugged into a hub before then.

Now the S3 is detected when using both the direct USB port of the PC and via the hub.

NOTE - You may need to also run adb devices from the command line to get your S3 to re-request permission.

UPDATE 2016-03-02: As of Docker 1.9.0, Docker has named volumes which replace data-only containers. The answer below, as well as my linked blog post, still has value in the sense of how to think about data inside docker but consider using named volumes to implement the pattern described below rather than data containers.

I believe the canonical way to solve this is by using data-only containers. With this approach, all access to the volume data is via containers that use -volumes-from the data container, so the host uid/gid doesn't matter.

For example, one use case given in the documentation is backing up a data volume. To do this another container is used to do the backup via tar, and it too uses -volumes-from in order to mount the volume. So I think the key point to grok is: rather than thinking about how to get access to the data on the host with the proper permissions, think about how to do whatever you need -- backups, browsing, etc. -- via another container. The containers themselves need to use consistent uid/gids, but they don't need to map to anything on the host, thereby remaining portable.

This is relatively new for me as well but if you have a particular use case feel free to comment and I'll try to expand on the answer.

UPDATE: For the given use case in the comments, you might have an image some/graphite to run graphite, and an image some/graphitedata as the data container. So, ignoring ports and such, the Dockerfile of image some/graphitedata is something like:

FROM debian:jessie
# add our user and group first to make sure their IDs get assigned consistently, regardless of other deps added later
RUN groupadd -r graphite \
  && useradd -r -g graphite graphite
RUN mkdir -p /data/graphite \
  && chown -R graphite:graphite /data/graphite
VOLUME /data/graphite
USER graphite
CMD ["echo", "Data container for graphite"]

Build and create the data container:

docker build -t some/graphitedata Dockerfile
docker run --name graphitedata some/graphitedata

The some/graphite Dockerfile should also get the same uid/gids, therefore it might look something like this:

FROM debian:jessie
# add our user and group first to make sure their IDs get assigned consistently, regardless of other deps added later
RUN groupadd -r graphite \
  && useradd -r -g graphite graphite
# ... graphite installation ...
VOLUME /data/graphite
USER graphite
CMD ["/bin/graphite"]

And it would be run as follows:

docker run --volumes-from=graphitedata some/graphite

Ok, now that gives us our graphite container and associated data-only container with the correct user/group (note you could re-use the some/graphite container for the data container as well, overriding the entrypoing/cmd when running it, but having them as separate images IMO is clearer).

Now, lets say you want to edit something in the data folder. So rather than bind mounting the volume to the host and editing it there, create a new container to do that job. Lets call it some/graphitetools. Lets also create the appropriate user/group, just like the some/graphite image.

FROM debian:jessie
# add our user and group first to make sure their IDs get assigned consistently, regardless of other deps added later
RUN groupadd -r graphite \
  && useradd -r -g graphite graphite
VOLUME /data/graphite
USER graphite
CMD ["/bin/bash"]

You could make this DRY by inheriting from some/graphite or some/graphitedata in the Dockerfile, or instead of creating a new image just re-use one of the existing ones (overriding entrypoint/cmd as necessary).

Now, you simply run:

docker run -ti --rm --volumes-from=graphitedata some/graphitetools

and then vi /data/graphite/whatever.txt. This works perfectly because all the containers have the same graphite user with matching uid/gid.

Since you never mount /data/graphite from the host, you don't care how the host uid/gid maps to the uid/gid defined inside the graphite and graphitetools containers. Those containers can now be deployed to any host, and they will continue to work perfectly.

The neat thing about this is that graphitetools could have all sorts of useful utilities and scripts, that you can now also deploy in a portable manner.

UPDATE 2: After writing this answer, I decided to write a more complete blog post about this approach. I hope it helps.

UPDATE 3: I corrected this answer and added more specifics. It previously contained some incorrect assumptions about ownership and perms -- the ownership is usually assigned at volume creation time i.e. in the data container, because that is when the volume is created. See this blog. This is not a requirement though -- you can just use the data container as a "reference/handle" and set the ownership/perms in another container via chown in an entrypoint, which ends with gosu to run the command as the correct user. If anyone is interested in this approach, please comment and I can provide links to a sample using this approach.

If you are sure you haven't messed the jar, then please clean the project and perform mvn clean install. This should solve the problem.

I solved this by using this way -

    @RunWith(SpringRunner.class)
    @EnableJpaRepositories(basePackages={"com.path.repositories"})
    @EntityScan(basePackages={"com.model"})
    @TestPropertySource("classpath:application.properties")
    @ContextConfiguration(classes = {ApiTestConfig.class,SaveActionsServiceImpl.class})
    public class SaveCriticalProcedureTest {

        @Autowired
        private SaveActionsService saveActionsService;
        .......
        .......
}

Try forcing ADB to create new keys.

• On Linux:

  $ mv ~/.android/adbkey ~/.android/adbkey.old
  $ mv ~/.android/adbkey.pub ~/.android/adbkey.pub.old
  $ adb kill-server
  $ adb start-server
  

• On Windows 10 (thank you, Pau Coma Ramirez, Naveen and d4c0d312!):

  • Go to %HOMEPATH%\Android\.android\
  • Look for files called adbkey or adbkey.pub.
  • Delete these files. Or, if you want to be on the safe side, move them to another directory.
  • Repeat the above steps in %USERPROFILE%\.android\
  • Try again

After this I didn't even need to unplug my phone: the authorization prompt was already there. Good luck!

t indicates for text mode

https://docs.python.org/release/3.1.5/library/functions.html#open

on linux, there's no difference between text mode and binary mode, however, in windows, they converts \n to \r\n when text mode.

If your your list is dynamically generated with unknown number and your target is to always have last div in a new line set last div class to "col-xl-12" and remove other classes so it will always take a full row.

This is a copy of your code corrected so that last div always occupy a full row (I although removed unnecessary classes).

<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" rel="stylesheet">_x000D_
<div class="grid">_x000D_
  <div class="row">_x000D_
    <div class="col-sm-3">Under me should be a DIV</div>_x000D_
    <div class="col-md-6 col-sm-5">Under me should be a DIV</div>_x000D_

Override onConfigurationChanged and dismiss progress dialog. If progress dialog is created in portrait and dismisses in landscape then it will throw View not attached to window manager error.

Also stop the progress bar and stop the async task in onPause(), onBackPressed and onDestroy method.

if(asyncTaskObj !=null && asyncTaskObj.getStatus().equals(AsyncTask.Status.RUNNING)){

    asyncTaskObj.cancel(true);

}

I faced the same problem but When I changed the skin of AVD device to HVGA, it worked.

You need to make sure requestAnimFrame stops being called once game == 1. A break statement only exits a traditional loop (e.g. while()).

function loop() {
    if (isPlaying) {
        jet1.draw();
        drawAllEnemies();
        if (game != 1) {
            requestAnimFrame(loop);
        }
    }
}

Or alternatively you could simply skip the second if condition and change the first condition to if (isPlaying && game !== 1). You would have to make a variable called game and give it a value of 0. Add 1 to it every game.

You need other headers, not only access-control-allow-origin. If your request have the "Access-Control-Allow-Origin" header, you must copy it into the response headers, If doesn't, you must check the "Origin" header and copy it into the response. If your request doesn't have Access-Control-Allow-Origin not Origin headers, you must return "*".

You can read the complete explanation here: http://www.html5rocks.com/en/tutorials/cors/#toc-adding-cors-support-to-the-server

and this is the function I'm using to write cross domain headers:

func writeCrossDomainHeaders(w http.ResponseWriter, req *http.Request) {
    // Cross domain headers
    if acrh, ok := req.Header["Access-Control-Request-Headers"]; ok {
        w.Header().Set("Access-Control-Allow-Headers", acrh[0])
    }
    w.Header().Set("Access-Control-Allow-Credentials", "True")
    if acao, ok := req.Header["Access-Control-Allow-Origin"]; ok {
        w.Header().Set("Access-Control-Allow-Origin", acao[0])
    } else {
        if _, oko := req.Header["Origin"]; oko {
            w.Header().Set("Access-Control-Allow-Origin", req.Header["Origin"][0])
        } else {
            w.Header().Set("Access-Control-Allow-Origin", "*")
        }
    }
    w.Header().Set("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE")
    w.Header().Set("Connection", "Close")

}

Please check that your key exists in the array or not, instead of simply trying to access it.

Replace:

$myVar = $someArray['someKey']

With something like:

if (isset($someArray['someKey'])) {
    $myVar = $someArray['someKey']
}

or something like:

if(is_array($someArray['someKey'])) {
    $theme_img = 'recent_works_iso_thumbnail';
}else {
    $theme_img = 'recent_works_iso_thumbnail';
}

This code worked for me

public static void main(String[] args) {
    try {
        java.net.URL myUr = new java.net.URL("http://path");
        System.out.println("Instantiated new URL: " + connection_url);
    }
    catch (MalformedURLException e) {
        e.printStackTrace();
    }
}

Instantiated new URL: http://path

On the phone make sure that the debugging mode is turned on.

In my case, i was inflating a view with ApplicationContext. When you use ApplicationContext, theme/style is not applied, so although there was Theme.Appcompat in my style, it was not applied and caused this exception. More details: Theme/Style is not applied when inflater used with ApplicationContext

Most probably it has to do with caching on the device. Catching the exception and ignoring is not nice but my problem was fixed and it seems to work.

The Oracle error ORA-01036 means that the query uses an undefined variable somewhere. From the query we can determine which variables are in use, namely all that start with @. However, if you're inputting this into an advanced query, it's important to confirm that all variables have a matching input parameter, including the same case as in the variable name, if your Oracle database is Case Sensitive.

I was able to go around the whole thing by replacing the context reference from this or Context.this to getapplicationcontext.

My answer refers to a special case of the general problem the OP describes, but I'll add it just in case it helps somebody out.

When using @EnableOAuth2Sso, Spring puts an OAuth2RestTemplate on the application context, and this component happens to assume thread-bound servlet-related stuff.

My code has a scheduled async method that uses an autowired RestTemplate. This isn't running inside DispatcherServlet, but Spring was injecting the OAuth2RestTemplate, which produced the error the OP describes.

The solution was to do name-based injection. In the Java config:

@Bean
public RestTemplate pingRestTemplate() {
    return new RestTemplate();
}

and in the class that uses it:

@Autowired
@Qualifier("pingRestTemplate")
private RestTemplate restTemplate;

Now Spring injects the intended, servlet-free RestTemplate.

Another option may be to have your fragment implement View.OnClickListener and override onClick(View v) within your fragment. If you need to have your fragment talk to the activity simply add an interface with desired method(s) and have the activity implement the interface and override its method(s).

public class FragName extends Fragment implements View.OnClickListener { 
    public FragmentCommunicator fComm;
    public ImageButton res1, res2;
    int c;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        return inflater.inflate(R.layout.fragment_test, container, false);
    }

    @Override
    public void onAttach(Activity activity) {
        super.onAttach(activity);
        try {
            fComm = (FragmentCommunicator) activity;
        } catch (ClassCastException e) {
            throw new ClassCastException(activity.toString()
                    + " must implement FragmentCommunicator");
        }
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        res1 = (ImageButton) getActivity().findViewById(R.id.responseButton1);
        res1.setOnClickListener(this);
        res2 = (ImageButton) getActivity().findViewById(R.id.responseButton2);
        res2.setOnClickListener(this);
    }
    public void onClick(final View v) { //check for what button is pressed
            switch (v.getId()) {
                case R.id.responseButton1:
                  c *= fComm.fragmentContactActivity(2);
                  break;
                case R.id.responseButton2:
                  c *= fComm.fragmentContactActivity(4);
                  break;
                default:
                  c *= fComm.fragmentContactActivity(100);
                  break;
    }
    public interface FragmentCommunicator{
        public int fragmentContactActivity(int b);
    }



public class MainActivity extends FragmentActivity implements FragName.FragmentCommunicator{
    int a = 10;
    //variable a is update by fragment. ex. use to change textview or whatever else you'd like.

    public int fragmentContactActivity(int b) {
        //update info on activity here
        a += b;
        return a;
    }
}

I'm not sure what happened in your case that fixed the issue, but your issue was on this line:

Caused by: java.lang.NoClassDefFoundError: javax/xml/rpc/handler/soap/SOAPMessageContext

You need to add jaxrpc-api.jar to your /libs or add

<dependency>
    <groupId>javax.xml</groupId>
    <artifactId>jaxrpc-api</artifactId>
    <version>x.x.x</version>
</dependency>

to your maven dependencies.

Try

let a = document.createElement('a');
a.href = "data:application/octet-stream,"+encodeURIComponent("My DATA");
a.download = 'abc.txt';
a.click();

If you want to download binary data look here

Update

2020.06.14 I upgrade Chrome to 83.0 and above SO snippet stop works (reason: sandbox security restrictions) - but JSFiddle version works - here

Response you are getting is in object form i.e.

{ 
  "dstOffset" : 3600, 
  "rawOffset" : 36000, 
  "status" : "OK", 
  "timeZoneId" : "Australia/Hobart", 
  "timeZoneName" : "Australian Eastern Daylight Time" 
}

Replace below line of code :

List<Post> postsList = Arrays.asList(gson.fromJson(reader,Post.class))

with

Post post = gson.fromJson(reader, Post.class);

I was looking for a solution for Windows but didn't found any. Finally, figured out that that there is a dangling java application using the port. Maybe it's the earlier instance of the spring application and ended the process.

I used tcpview from Microsoft. It shows services/applications using which port on your computer.

You can end the process. And Done!

Did you include "bootstrap-theme.css" files on your code?

In "bootstrap-theme.min.css" files, background-image about ".active" is existed for "navbar" (check this screenshot: http://i.imgur.com/1etLIyY.png).

It will re-declare your style code, and then it will be effected on your code.

So after you delete or re-declare them (background-image), you can use your background color style about the ".active" tag.

WunderBart's answer was the best for me. Note that you can speed it up a lot if your images are often the right way around, simply by testing the orientation first and bypassing the rest of the code if no rotation is required.

Putting all of the info from wunderbart together, something like this;

var handleTakePhoto = function () {
    let fileInput: HTMLInputElement = <HTMLInputElement>document.getElementById('photoInput');
    fileInput.addEventListener('change', (e: any) => handleInputUpdated(fileInput, e.target.files));
    fileInput.click();
}

var handleInputUpdated = function (fileInput: HTMLInputElement, fileList) {
    let file = null;

    if (fileList.length > 0 && fileList[0].type.match(/^image\//)) {
        isLoading(true);
        file = fileList[0];
        getOrientation(file, function (orientation) {
            if (orientation == 1) {
                imageBinary(URL.createObjectURL(file));
                isLoading(false);
            }
            else 
            {
                resetOrientation(URL.createObjectURL(file), orientation, function (resetBase64Image) {
                    imageBinary(resetBase64Image);
                    isLoading(false);
                });
            }
        });
    }

    fileInput.removeEventListener('change');
}

I had this problem before and I made fallback way for loading. Basically first way work within .jar file and second way works within eclipse or other IDE.

public class MyClass {

    public static InputStream accessFile() {
        String resource = "my-file-located-in-resources.txt";

        // this is the path within the jar file
        InputStream input = MyClass.class.getResourceAsStream("/resources/" + resource);
        if (input == null) {
            // this is how we load file within editor (eg eclipse)
            input = MyClass.class.getClassLoader().getResourceAsStream(resource);
        }

        return input;
    }
}

ADB and driver versions matter. The newer the device, the lower the chances of an older version ADB to work correctly.

Apps using their own ADB copy need to be updated or at least have their ADB updated manually.

When installing Helium / Carbon for instance, it uses an old / incomplete ADB. Newer devices might not link to the ADB server for this very reason.

What I'm writing here should work for any future devices on Windows and possibly *nix OSes.

First the systems must be prepared. on Android:

• activate developer mode, either from an app (like Helium, when prompted) or by accessing the about phone section, taping build number until the developer mode unlocks
• in developer settings enable USB debugging
• in security settings allow unknown sources
• (when connected with USB cable) set USB connectivity to PTP mode (camera device, if so labeled)

in Windows:

• uninstall older USB driver (with file removal) if there is one, but only when the device is connected and in developer mode, otherwise that particular device won't be listed
• install latest USB driver after the device has been plugged in and developer mode is active, the device will be listed as unknown or other in Device Manager; the drivers can be downloaded separately from Google Android support site, these are the same as vendor drivers, with only fewer ID's in inf file making the driver not being recognized for all Android devices
• if the driver does not recognise the device, no problem, install it generically: Manual Install > Show All Devices > Have Disk > pick inf location of the Android USB driver and from the list select Android ADB Interface; there's not need to edit the inf by adding hardware ids, the end result is the same
• each of the modes, PTP and MTP will have their own driver entry, so if the device asks for MTP, the same driver installation procedure must be followed, again

Once these steps are/were previously done correctly, adb must be tested. If Android SDK was installed previously, open a command prompt where adb.exe is and test the listing of the device.

adb start-server IMPORTANT NOTE: This command will prompt the device to allow the communication between the computer it's been linked to on the first run. The prompt will also list an RSA key specific to the PC in question. Without this prompt on start-server, ADB will NOT work! Nor will any application relying on ADB.

adb devices Must list the device(s). If the list is empty, and most likely the RSA prompt did not occur, then no communication will work. If the list is empty the current ADB (and SDK) must be updated or installed fresh (in the case of apps bringing in their own ADB runtime, like Helium / Carbon).

In the case of applications that do bring their own ADB, if the version is old, and these apps insist in using it instead of the SDK one, these files need to be replaced with the latest ones from Android SDK. Plain and simple copy & paste.

As for Android SDK, the only required packages to be installed are SDK Tools and Platform-tools. There, ADB.exe will need some support libraries, on Windows these files are AdbWinApi.dll and AdbWinUsbApi.dll. After all is done, the SDK can be uninstalled from SDK Manager while being able to retain the ADB tool if this is the only runtime used, depending on the case in question.

I was facing the same issue while auto-wiring the class from one of my jar file. I fixed the issue by using @Lazy annotation:

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Lazy;

    @Autowired
    @Lazy
    private IGalaxyCommand iGalaxyCommand;

I got same error in my Micro-service, whenever you declare @Value annotation in program i.e @Value("${project.api.key}")

make sure that your application.properties file with same values should not be blank project.api.key= add some values

MostIMP :otherwise it will throw error "Error creating bean with name 'ServiceFTP': Injection of autowired dependencies"

package com.concepttimes.java;

import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;

public class IllegalStateExceptionDemo {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        List al = new ArrayList();
        al.add("Sachin");
        al.add("Rahul");
        al.add("saurav");
        Iterator itr = al.iterator();  
        while (itr.hasNext()) {           
            itr.remove();
        }
    }
}

IllegalStateException signals that method has been invoked at the wrong time. In this below example, we can see that. remove() method is called at the same time element is being used in while loop.

Please refer to below link for more details. http://www.elitmuszone.com/elitmus/illegalstateexception-in-java/

$("#idofBtn").click(function(){
        $('#idofdropdown').empty(); //remove all child nodes
        var newOption = $('<option value="1">test</option>');
        $('#idofdropdown').append(newOption);
        $('#idofdropdown').trigger("chosen:updated");
    });

In my case, the error "BeanFactory not initialized or already closed - call 'refresh' before" was a consequence of a previous error that I didn't noticed in the server startup. I think that it is not always the real cause of the problem.

Here is an updated version of Paul Burke's answer. In versions below Android 4.4 (KitKat) we don't have the DocumentsContract class.

In order to work on versions below KitKat create this class:

public class DocumentsContract {
    private static final String DOCUMENT_URIS =
        "com.android.providers.media.documents " +
        "com.android.externalstorage.documents " +
        "com.android.providers.downloads.documents " +
        "com.android.providers.media.documents";

    private static final String PATH_DOCUMENT = "document";
    private static final String TAG = DocumentsContract.class.getSimpleName();

    public static String getDocumentId(Uri documentUri) {
        final List<String> paths = documentUri.getPathSegments();
        if (paths.size() < 2) {
            throw new IllegalArgumentException("Not a document: " + documentUri);
        }

        if (!PATH_DOCUMENT.equals(paths.get(0))) {
            throw new IllegalArgumentException("Not a document: " + documentUri);
        }
        return paths.get(1);
    }

    public static boolean isDocumentUri(Uri uri) {
        final List<String> paths = uri.getPathSegments();
        Logger.v(TAG, "paths[" + paths + "]");
        if (paths.size() < 2) {
            return false;
        }
        if (!PATH_DOCUMENT.equals(paths.get(0))) {
            return false;
        }
        return DOCUMENT_URIS.contains(uri.getAuthority());
    }
}

This requires no special permissions, and works with the Storage Access Framework, as well as the unofficial ContentProvider pattern (file path in _data field).

Initialize instance:

private String imagePath;
private List<String> imagePathList;

In onActivityResult You have to write this, If-else 2 block. One for single image and another for multiple image.

if (requestCode == GALLERY_CODE && resultCode == RESULT_OK  && data != null){

    imagePathList = new ArrayList<>();

    if(data.getClipData() != null){

        int count = data.getClipData().getItemCount();
        for (int i=0; i<count; i++){

            Uri imageUri = data.getClipData().getItemAt(i).getUri();
            getImageFilePath(imageUri);
        }
    }
    else if(data.getData() != null){

        Uri imgUri = data.getData();
        getImageFilePath(imgUri);
    }
}

Most important part, Get Image Path from uri:

public void getImageFilePath(Uri uri) {

    File file = new File(uri.getPath());
    String[] filePath = file.getPath().split(":");
    String image_id = filePath[filePath.length - 1];

    Cursor cursor = getContentResolver().query(android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI, null, MediaStore.Images.Media._ID + " = ? ", new String[]{image_id}, null);
    if (cursor!=null) {
        cursor.moveToFirst();
        imagePath = cursor.getString(cursor.getColumnIndex(MediaStore.Images.Media.DATA));
        imagePathList.add(imagePath);
        cursor.close();
    }
}

Hope this can help you.

Resolved the problem using Jackson library. Prints are called out of Main class and all POJO classes are created. Here is the code snippets.

MainClass.java

public class MainClass {
  public static void main(String[] args) throws JsonParseException, 
       JsonMappingException, IOException {

String jsonStr = "{\r\n" + "    \"id\": 2,\r\n" + " \"socket\": \"0c317829-69bf- 
             43d6-b598-7c0c550635bb\",\r\n"
            + " \"type\": \"getDashboard\",\r\n" + "    \"data\": {\r\n"
            + "     \"workstationUuid\": \"ddec1caa-a97f-4922-833f- 
            632da07ffc11\"\r\n" + " },\r\n"
            + " \"reply\": true\r\n" + "}";

    ObjectMapper mapper = new ObjectMapper();

    MyPojo details = mapper.readValue(jsonStr, MyPojo.class);

    System.out.println("Value for getFirstName is: " + details.getId());
    System.out.println("Value for getLastName  is: " + details.getSocket());
    System.out.println("Value for getChildren is: " + 
      details.getData().getWorkstationUuid());
    System.out.println("Value for getChildren is: " + details.getReply());

}

MyPojo.java

public class MyPojo {
    private String id;

    private Data data;

    private String reply;

    private String socket;

    private String type;

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public Data getData() {
        return data;
    }

    public void setData(Data data) {
        this.data = data;
    }

    public String getReply() {
        return reply;
    }

    public void setReply(String reply) {
        this.reply = reply;
    }

    public String getSocket() {
        return socket;
    }

    public void setSocket(String socket) {
        this.socket = socket;
    }

    public String getType() {
        return type;
    }

    public void setType(String type) {
        this.type = type;
    } 
}

Data.java

public class Data {
    private String workstationUuid;

    public String getWorkstationUuid() {
        return workstationUuid;
    }

    public void setWorkstationUuid(String workstationUuid) {
        this.workstationUuid = workstationUuid;
    }   
}

RESULTS:

Value for getFirstName is: 2
Value for getLastName  is: 0c317829-69bf-43d6-b598-7c0c550635bb
Value for getChildren is: ddec1caa-a97f-4922-833f-632da07ffc11
Value for getChildren is: true

In Tomcat a .java and .class file will be created for every jsp files with in the application and the same can be found from the path below, Apache-Tomcat\work\Catalina\localhost\'ApplicationName'\org\apache\jsp\index_jsp.java

In your case the jsp name is error.jsp so the path should be something like below Apache-Tomcat\work\Catalina\localhost\'ApplicationName'\org\apache\jsp\error_jsp.java in line no 124 you are trying to access a null object which results in null pointer exception.

My workaround had been using gnu sed. Worked fine for my purposes.

I believe that although javascript is an option here, you have a smoother animation through forcing hardware accelerate with CSS3. You can achieve this by setting the following CSS3 properties on the moving div:

div.hardware-accelarate {
     -webkit-transform: translate3d(0,0,0);
        -moz-transform: translate3d(0,0,0);
         -ms-transform: translate3d(0,0,0);
          -o-transform: translate3d(0,0,0);
             transform: translate3d(0,0,0);
}

I've made a plunkr setup for ya'll to test and tweak...

don't need regex just use classlist

var id=document.getElementById('myButton');


function toggle(el,classname){
if(el.classList.contains(classname)){
el.classList.remove(classname)
}
else{
el.classList.add(classname)
}
}




id.addEventListener('click',(e)=>{

toggle(e.target,'red')
})

.red{

background:red

}

<button id="myButton">Switch</button>

Simple Usage above Example

var id=document.getElementById('myButton');


function toggle(el,classname){
el.classList.toggle(classname)
}




id.addEventListener('click',(e)=>{

toggle(e.target,'red')
})

.red{

background:red

}

<button id="myButton">Switch</button>

The following code were written in ES6 and it will work in most of the browsers without an issue.

var test_array = [["name1", 2, 3], ["name2", 4, 5], ["name3", 6, 7], ["name4", 8, 9], ["name5", 10, 11]];_x000D_
_x000D_
// Construct the comma seperated string_x000D_
// If a column values contains a comma then surround the column value by double quotes_x000D_
const csv = test_array.map(row => row.map(item => (typeof item === 'string' && item.indexOf(',') >= 0) ? `"${item}"`: String(item)).join(',')).join('\n');_x000D_
_x000D_
// Format the CSV string_x000D_
const data = encodeURI('data:text/csv;charset=utf-8,' + csv);_x000D_
_x000D_
// Create a virtual Anchor tag_x000D_
const link = document.createElement('a');_x000D_
link.setAttribute('href', data);_x000D_
link.setAttribute('download', 'export.csv');_x000D_
_x000D_
// Append the Anchor tag in the actual web page or application_x000D_
document.body.appendChild(link);_x000D_
_x000D_
// Trigger the click event of the Anchor link_x000D_
link.click();_x000D_
_x000D_
// Remove the Anchor link form the web page or application_x000D_
document.body.removeChild(link);

The basic answer is: you need to iterate through loop and check any element contains the specified string. So, let's say the code is:

foreach(string item in myList)
{
    if(item.Contains(myString))
       return item;
}

The equivalent, but terse, code is:

mylist.Where(x => x.Contains(myString)).FirstOrDefault();

Here, x is a parameter that acts like "item" in the above code.

By adding filter action my problem resolved

 // Register for broadcasts when a device is discovered
    IntentFilter intentFilter = new IntentFilter();
    intentFilter.addAction(BluetoothDevice.ACTION_FOUND);
    intentFilter.addAction(BluetoothAdapter.ACTION_DISCOVERY_STARTED);
    intentFilter.addAction(BluetoothAdapter.ACTION_DISCOVERY_FINISHED);
    registerReceiver(mReceiver, intentFilter);

Here is a good tutorial with code. Let me know if it works for you! This is also a good tutorial.

EDIT

In This example, all you need to do is add this line:

gallery.setSelection(1);

after setting the adapter to gallery object, that is this line:

gallery.setAdapter(new ImageAdapter(this));

UPDATE1

Alright, I got your problem. This open source library is your solution. I also have used it for one of my projects. Hope this will solve your problem finally.

UPDATE2:

I would suggest you to go through this tutorial. You might get idea. I think I got your problem, you want the horizontal scrollview with snap. Try to search with that keyword on google or out here, you might get your solution.

tl;dr

With JDBC 4.2 or later and java 8 or later:

myPreparedStatement.setObject( … , myLocalDate  )

…and…

myResultSet.getObject( … , LocalDate.class )

Details

The Answer by Vargas is good about mentioning java.time types but refers only to converting to java.sql.Date. No need to convert if your driver is updated.

java.time

The java.time framework is built into Java 8 and later. These classes supplant the old troublesome date-time classes such as java.util.Date, .Calendar, & java.text.SimpleDateFormat. The Joda-Time team also advises migration to java.time.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations.

Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport and further adapted to Android in ThreeTenABP.

LocalDate

In java.time, the java.time.LocalDate class represents a date-only value without time-of-day and without time zone.

If using a JDBC driver compliant with JDBC 4.2 or later spec, no need to use the old java.sql.Date class. You can pass/fetch LocalDate objects directly to/from your database via PreparedStatement::setObject and ResultSet::getObject.

LocalDate localDate = LocalDate.now( ZoneId.of( "America/Montreal" ) );
myPreparedStatement.setObject( 1 , localDate  );

…and…

LocalDate localDate = myResultSet.getObject( 1 , LocalDate.class );

Before JDBC 4.2, convert

If your driver cannot handle the java.time types directly, fall back to converting to java.sql types. But minimize their use, with your business logic using only java.time types.

New methods have been added to the old classes for conversion to/from java.time types. For java.sql.Date see the valueOf and toLocalDate methods.

java.sql.Date sqlDate = java.sql.Date.valueOf( localDate );

…and…

LocalDate localDate = sqlDate.toLocalDate();

Placeholder value

Be wary of using 0000-00-00 as a placeholder value as shown in your Question’s code. Not all databases and other software can handle going back that far in time. I suggest using something like the commonly-used Unix/Posix epoch reference date of 1970, 1970-01-01.

LocalDate EPOCH_DATE = LocalDate.ofEpochDay( 0 ); // 1970-01-01 is day 0 in Epoch counting.

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

If you're only interested in bailing if a particular argument is missing, Parameter Substitution is great:

#!/bin/bash
# usage-message.sh

: ${1?"Usage: $0 ARGUMENT"}
#  Script exits here if command-line parameter absent,
#+ with following error message.
#    usage-message.sh: 1: Usage: usage-message.sh ARGUMENT

Since the settings object is tied to that ajax call, you can simply add in the indexer as a custom property, which you can then access using this in the success callback:

//preloader for images on gallery pages
window.onload = function() {
    var urls = ["./img/party/","./img/wedding/","./img/wedding/tree/"];

    setTimeout(function() {
        for ( var i = 0; i < urls.length; i++ ) {
            $.ajax({
                url: urls[i],
                indexValue: i,
                success: function(data) {
                    image_link(data , this.indexValue);

                    function image_link(data, i) {
                        $(data).find("a:contains(.jpg)").each(function(){ 
                            console.log(i);
                            new Image().src = urls[i] + $(this).attr("href");
                        });
                    }
                }
            });
        };  
    }, 1000);       
};

Edit: Adding in an updated JSFiddle example, as they seem to have changed how their ECHO endpoints work: https://jsfiddle.net/djujx97n/26/.

To understand how this works see the "context" field on the ajaxSettings object: http://api.jquery.com/jquery.ajax/, specifically this note:

"The this reference within all callbacks is the object in the context option passed to $.ajax in the settings; if context is not specified, this is a reference to the Ajax settings themselves."

Create an init() function and point the table layout. Then create the needed rows and columns.

   public void init() {
            TableLayout stk = (TableLayout) findViewById(R.id.table_main);
            TableRow tbrow0 = new TableRow(this);
            TextView tv0 = new TextView(this);
            tv0.setText(" Sl.No ");
            tv0.setTextColor(Color.WHITE);
            tbrow0.addView(tv0);
            TextView tv1 = new TextView(this);
            tv1.setText(" Product ");
            tv1.setTextColor(Color.WHITE);
            tbrow0.addView(tv1);
            TextView tv2 = new TextView(this);
            tv2.setText(" Unit Price ");
            tv2.setTextColor(Color.WHITE);
            tbrow0.addView(tv2);
            TextView tv3 = new TextView(this);
            tv3.setText(" Stock Remaining ");
            tv3.setTextColor(Color.WHITE);
            tbrow0.addView(tv3);

Call init function in your onCreate method:

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.activity_main);

        init();
    }

Layout file like:

 <ScrollView
        android:id="@+id/scrollView1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:background="#3d455b"
        android:layout_alignParentLeft="true" >

        <HorizontalScrollView
            android:id="@+id/hscrll1"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content" >

            <RelativeLayout
                android:id="@+id/RelativeLayout1"
                android:layout_width="fill_parent"
                android:layout_gravity="center"
                android:layout_height="fill_parent"
                android:orientation="vertical" >

                <TableLayout
                    android:id="@+id/table_main"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_centerHorizontal="true" >
                </TableLayout>
            </RelativeLayout>
        </HorizontalScrollView>
    </ScrollView>

Will look like:

I encountered this error when I was trying to create a DialogBox when some action is taken inside the CustomAdapter class. This was not an Activity but an Adapter class. After 36 hrs of efforts and looking up for solutions, I came up with this.

Send the Activity as a parameter while calling the CustomAdapter.

CustomAdapter ca = new CustomAdapter(MyActivity.this,getApplicationContext(),records);

Define the variables in the custom Adapter.

Activity parentActivity;
Context context;

Call the constructor like this.

public CustomAdapter(Activity parentActivity,Context context,List<Record> records){
    this.parentActivity=parentActivity;
    this.context=context;
    this.records=records;
}

And finally when creating the dialog box inside the adapter class, do it like this.

AlertDialog ad = new AlertDialog.Builder(parentActivity).setTitle("Your title");

and so on..

I hope this helps you

An error message that begins Parse error: syntax error, unexpected ':' can be caused by mistakenly writing a class static reference Class::$Variable as Class:$Variable.

I solved this problem on my Galaxy S4 phone by replacing context.startActivity(addAccountIntent); with startActivity(new Intent(Settings.ACTION_ADD_ACCOUNT));

I had the same problem. I set url in that way:

git remote set-url origin https://github.com/zkirkland/Random-Python-Tests.git

I also removed from config file this entry: askpass = /bin/echo. Then "git push" asked me for username and password and this time it worked.

I have figured out how this is done for Sony devices.

I've blogged about it here. I've also posted a seperate SO question about this here.

Sony devices use a class named BadgeReciever.

1. Declare the com.sonyericsson.home.permission.BROADCAST_BADGE permission in your manifest file:

2. Broadcast an Intent to the BadgeReceiver:

   Intent intent = new Intent();
   
   intent.setAction("com.sonyericsson.home.action.UPDATE_BADGE");
   intent.putExtra("com.sonyericsson.home.intent.extra.badge.ACTIVITY_NAME", "com.yourdomain.yourapp.MainActivity");
   intent.putExtra("com.sonyericsson.home.intent.extra.badge.SHOW_MESSAGE", true);
   intent.putExtra("com.sonyericsson.home.intent.extra.badge.MESSAGE", "99");
   intent.putExtra("com.sonyericsson.home.intent.extra.badge.PACKAGE_NAME", "com.yourdomain.yourapp");
   
   sendBroadcast(intent);
   

3. Done. Once this Intent is broadcast the launcher should show a badge on your application icon.

4. To remove the badge again, simply send a new broadcast, this time with SHOW_MESSAGE set to false:

   intent.putExtra("com.sonyericsson.home.intent.extra.badge.SHOW_MESSAGE", false);
   

I've excluded details on how I found this to keep the answer short, but it's all available in the blog. Might be an interesting read for someone.

You actually do not want to get the path to your main class. According to your example you want to get the current working directory, i.e. directory where your program started. In this case you can just say new File(".").getAbsolutePath()

For editing use

vi galfit.feedme //if user has file editing permissions

or

sudo vi galfit.feedme //if user doesn't have file editing permissions

For inserting

Press i //Do required editing

For exiting

Press Esc

    :wq //for exiting and saving
    :q! //for exiting without saving

So the solution to the original problem is that you don't need both the "@see" and the "{@link...}" references on the same line. The "@link" tag is self-sufficient and, as noted, you can put it anywhere in the javadoc block. So you can mix the two approaches:

/**
 * some javadoc stuff
 * {@link com.my.package.Class#method()}
 * more stuff
 * @see com.my.package.AnotherClass
 */

In the project into the folder Libraries-->right click --> Add Library --> Mysqlconnector 5.1

The problem is that there is no app installed to handle opening the PDF. You should use the Intent Chooser, like so:

File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath() +"/"+ filename);
Intent target = new Intent(Intent.ACTION_VIEW);
target.setDataAndType(Uri.fromFile(file),"application/pdf");
target.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);

Intent intent = Intent.createChooser(target, "Open File");
try {
    startActivity(intent);
} catch (ActivityNotFoundException e) {
    // Instruct the user to install a PDF reader here, or something
}   

A few comments:

import sun.misc.*; Don't do this. It is non-standard and not guaranteed to be the same between implementations. There are other libraries with Base64 conversion available.

byte[] encVal = c.doFinal(Data.getBytes()); You are relying on the default character encoding here. Always specify what character encoding you are using: byte[] encVal = c.doFinal(Data.getBytes("UTF-8")); Defaults might be different in different places.

As @thegrinner pointed out, you need to explicitly check the length of your byte arrays. If there is a discrepancy, then compare them byte by byte to see where the difference is creeping in.

FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("../view/Main.fxml")); 

in my case i just remove ..

FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("/view/Main.fxml")); 

If you are using Maven, add the below config in your pom.xml:

<build>
    <testResources>
                <testResource>
                    <directory>src/main/webapp</directory>
                </testResource>
    </testResources>
</build>

With this config, you will be able to access xml files in WEB-INF folder. From Maven POM Reference: The testResources element block contains testResource elements. Their definitions are similar to resource elements, but are naturally used during test phases.

Yowsup provide best solution with example.you can download api from https://github.com/tgalal/yowsup let me know if you have any issue.

Use this Youtube Embed API from google.

Simplest way I've found:

in your activity XML add these lines:

<ListView 
... 
android:choiceMode="singleChoice"
android:listSelector="#666666"
/>

or programatically set these properties:

listView.setSelector(Drawable selector)
listView.setSelector(int resourceId)

My particular example:

   <ListView
            android:choiceMode="singleChoice"
            android:listSelector="#666666"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:id="@+id/listView"/>

same thing as Nic007 said before.

You do need to write code inside "onCreate" method. Sorry me too for the indent... (first comment here)

The package manager (“installer”) has a design problem: it can’t distinguish between a bunch of possible errors and regularly comes up with the “insufficient storage” excuse.

The first steps are done: identify it’s an install problem (1.) and not related to storage shortage (2.)

3. It happens on the console (pm install file.apk), with Google Play, other markets and manual GUI-install (for example, “clicking” on a downloaded APK file); it is not a download issue, ...
4. Packages end up entirely on the /data partition -or- mostly on the SD card (and a little on /data). – Both places show enough space as indicated by the original poster (33 MB and >900 MB respectively) for the <20 MB package. –And– the /data partition has more than 10% free (33 MB is more than 10% of 200 MB).

Surprisingly most answers don’t take this into account...

In reality, the /data partition needs a cleanup from residues from previous installs.

• Identify the common name of the problematic package (for example, com.abc.def)
• Uninstall the package (for example, pm uninstall com.abc.def)
• Check what’s left of it in data (for example, find /data -name 'com.abc.def*')
• Delete that stuff

The installer chokes on those, returning with the wrong reason. – The interesting part is: if the package gets installed on the SD card (forced or by other means) some (all?) leftovers on /data don’t hurt... which leads to the false belief that it is indeed a space problem (more space on the SD card...)!

The Stack Overflow question where I got half of this from is Solution to INSTALL_FAILED_INSUFFICIENT_STORAGE error on Android.

I really liked this answer, with ngBind, your default text can just live in the element body, and then if the ngBind evaluates to something non-null/undefined, your content is replaced automatically, and everythings happy

angularjs setting default values to display before evaluation

While Python 3 deals in Unicode, the Windows console or POSIX tty that you're running inside does not. So, whenever you print, or otherwise send Unicode strings to stdout, and it's attached to a console/tty, Python has to encode it.

The error message indirectly tells you what character set Python was trying to use:

  File "C:\Python32\lib\encodings\cp850.py", line 19, in encode

This means the charset is cp850.

You can test or yourself that this charset doesn't have the appropriate character just by doing '\u2013'.encode('cp850'). Or you can look up cp850 online (e.g., at Wikipedia).

It's possible that Python is guessing wrong, and your console is really set for, say UTF-8. (In that case, just manually set sys.stdout.encoding='utf-8'.) It's also possible that you intended your console to be set for UTF-8 but did something wrong. (In that case, you probably want to follow up at superuser.com.)

But if nothing is wrong, you just can't print that character. You will have to manually encode it with one of the non-strict error-handlers. For example:

>>> '\u2013'.encode('cp850')
UnicodeEncodeError: 'charmap' codec can't encode character '\u2013' in position 0: character maps to <undefined>
>>> '\u2013'.encode('cp850', errors='replace')
b'?'

So, how do you print a string that won't print on your console?

You can replace every print function with something like this:

>>> print(r['body'].encode('cp850', errors='replace').decode('cp850'))
?

… but that's going to get pretty tedious pretty fast.

The simple thing to do is to just set the error handler on sys.stdout:

>>> sys.stdout.errors = 'replace'
>>> print(r['body'])
?

For printing to a file, things are pretty much the same, except that you don't have to set f.errors after the fact, you can set it at construction time. Instead of this:

with open('path', 'w', encoding='cp850') as f:

Do this:

with open('path', 'w', encoding='cp850', errors='replace') as f:

… Or, of course, if you can use UTF-8 files, just do that, as Mark Ransom's answer shows:

with open('path', 'w', encoding='utf-8') as f:

@Test
public void testSearchManagementStaff() throws SQLException
{
    boolean res=true;
    ManagementDaoImp mdi=new ManagementDaoImp();
    boolean b=mdi.searchManagementStaff("[email protected]"," 123456");
    assertEquals(res,b);
}

Late but I hope this helps someone.

I have my JAX RS defined like this:

@Path("/examplepath")
@RequestScoped //this make the diference
public class ExampleResource {

Then, in my code finally I can inject:

@Inject
SomeManagedBean bean;

In my case, the SomeManagedBean is an ApplicationScoped bean.

Hope this helps to anyone.

In my experience, most often this error message means that you have put an accidental closing brace somewhere, leaving the rest of your statements outside the function.

Example:

function a() {
    if (global_block) //syntax error is actually here - missing opening brace
       return;
    } //this unintentionally ends the function

    if (global_somethingelse) {
       //Chrome will show the error occurring here, 
       //but actually the error is in the previous statement
       return; 
    }

    //do something
}

Thread.sleep() could work in most cases, but usually if you're waiting, you are actually waiting for a particular condition or state to occur. Thread.sleep() does not guarantee that whatever you're waiting for has actually happened.

If you are waiting on a rest request for example maybe it usually return in 5 seconds, but if you set your sleep for 5 seconds the day your request comes back in 10 seconds your test is going to fail.

To remedy this JayWay has a great utility called Awatility which is perfect for ensuring that a specific condition occurs before you move on.

It has a nice fluent api as well

await().until(() -> 
{
    return yourConditionIsMet();
});

HTML

<div class="thumb" data-image-src="img/image.png">

jQuery

$( ".thumb" ).each(function() {
  var attr = $(this).attr('data-image-src');

  if (typeof attr !== typeof undefined && attr !== false) {
      $(this).css('background', 'url('+attr+')');
  }

});

Demo on JSFiddle

You could do this also with JavaScript.

To make images adjustable/flexible you could use this:

/* fit images to container */
.container img {
    max-width: 100%;
    height: auto;
}

I faced the same problem when I renamed my repository on GitHub. I tried to push at which point I got the error

fatal: 'origin' does not appear to be a git repository
fatal: The remote end hung up unexpectedly

I had to change the URL using

git remote set-url origin ssh://[email protected]/username/newRepoName.git

After this all commands started working fine. You can check the change by using

git remote -v

In my case after successfull change it showed correct renamed repo in URL

[aniket@alok Android]$ git remote -v
origin  ssh://[email protected]/aniket91/TicTacToe.git (fetch)
origin  ssh://[email protected]/aniket91/TicTacToe.git (push)

Here are the instructions from github:

touch README.md
git init
git add README.md
git commit -m "first commit"
git remote add origin https://github.com/tqisjim/google-oauth.git
git push -u origin master

Here's what actually worked:

touch README.md
git init
git add README.md
git commit -m "first commit"
git remote add origin https://github.com/tqisjim/google-oauth.git
git clone origin master

After cloning, then the push command succeeds by prompting for a username and password

as_json

You should use as_json method which converts ActiveRecord objects to Ruby Hashes despite its name

tasks_records = TaskStoreStatus.all
tasks_records = tasks_records.as_json

# You can now add new records and return the result as json by calling `to_json`

tasks_records << TaskStoreStatus.last.as_json
tasks_records << { :task_id => 10, :store_name => "Koramanagala", :store_region => "India" }
tasks_records.to_json

serializable_hash

You can also convert any ActiveRecord objects to a Hash with serializable_hash and you can convert any ActiveRecord results to an Array with to_a, so for your example :

tasks_records = TaskStoreStatus.all
tasks_records.to_a.map(&:serializable_hash)

And if you want an ugly solution for Rails prior to v2.3

JSON.parse(tasks_records.to_json) # please don't do it

if ($inputs['type'] == 'attach') {

The code is valid, but it expects the function parameter $inputs to be an array. The "Illegal string offset" warning when using $inputs['type'] means that the function is being passed a string instead of an array. (And then since a string offset is a number, 'type' is not suitable.)

So in theory the problem lies elsewhere, with the caller of the code not providing a correct parameter.

However, this warning message is new to PHP 5.4. Old versions didn't warn if this happened. They would silently convert 'type' to 0, then try to get character 0 (the first character) of the string. So if this code was supposed to work, that's because abusing a string like this didn't cause any complaints on PHP 5.3 and below. (A lot of old PHP code has experienced this problem after upgrading.)

You might want to debug why the function is being given a string by examining the calling code, and find out what value it has by doing a var_dump($inputs); in the function. But if you just want to shut the warning up to make it behave like PHP 5.3, change the line to:

if (is_array($inputs) && $inputs['type'] == 'attach') {

When talking about "bad input", you should consider where the input is coming from.

Is the input entered by a user or another external system you don't control, you should expect the input to be invalid, and always validate it. It's perfectly ok to throw a checked exception in this case. Your application should 'recover' from this exception by providing an error message to the user.

If the input originates from your own system, e.g. your database, or some other parts of your application, you should be able to rely on it to be valid (it should have been validated before it got there). In this case it's perfectly ok to throw an unchecked exception like an IllegalArgumentException, which should not be caught (in general you should never catch unchecked exceptions). It is a programmer's error that the invalid value got there in the first place ;) You need to fix it.

Wanted to add that my problem was in an activity where I tried to make a FragmentTransaction in onCreate BEFORE I called super.onCreate(). I just moved super.onCreate() to top of function and was worked fine.

When a clearfix is used in a parent container, it automatically wraps around all the child elements.

It is usually used after floating elements to clear the float layout.

When float layout is used, it will horizontally align the child elements. Clearfix clears this behaviour.

Example - Bootstrap Panels

In bootstrap, when the class panel is used, there are 3 child types: panel-header, panel-body, panel-footer. All of which have display:block layout but panel-body has a clearfix pre-applied. panel-body is a main container type whereas panel-header & panel-footer isn't intended to be a container, it is just intended to hold some basic text.

If floating elements are added, the parent container does not get wrapped around those elements because the height of floating elements is not inherited by the parent container.

So for panel-header & panel-footer, clearfix is needed to clear the float layout of elements: Clearfix class gives a visual appearance that the height of the parent container has been increased to accommodate all of its child elements.

 <div class="container">
    <div class="panel panel-default">
        <div class="panel-footer">
            <div class="col-xs-6">
                <input type="button" class="btn btn-primary"   value="Button1">
                <input type="button" class="btn btn-primary"   value="Button2">
                <input type="button" class="btn btn-primary"   value="Button3">
            </div>
        </div>
    </div>

    <div class="panel panel-default">
        <div class="panel-footer">
            <div class="col-xs-6">
                <input type="button" class="btn btn-primary"   value="Button1">
                <input type="button" class="btn btn-primary"   value="Button2">
                <input type="button" class="btn btn-primary"   value="Button3">
            </div>
            <div class="clearfix"/>
        </div>
    </div>
</div>

I found a solution to this. It's bloody witchcraft, but it works.

When you install the client, open Control Panel > Network Connections.

You'll see a disabled network connection that was added by the TAP installer (Local Area Connection 3 or some such).

Right Click it, click Enable.

The device will not reset itself to enabled, but that's ok; try connecting w/ the client again. It'll work.

For others who landed in this error and it's not 100% related to the OP question, please check that you are passing the value and it is not null in case of spring-boot: @Value annotation.

Here's the solution,

If you are a constant proxy changer like me for various reasons (university, home , workplace and so on..) you are mostly likely to get this error due to improper configuration of connection settings in the eclipse IDE. all you have to do it play around with the current settings and get it to working state. Here's how,,

1. GO TO

Window-> Preferences -> General -> Network Connection.

2. Change the Settings

Active Provider-> Manual-> and check---> HTTP, HTTPS and SOCKS

If your active provider is already set to Manual, try restoring the default (native)

That's all, restart Eclipse and you are good to go!

You can now do this without the use of Android SDK.

In the latest version of chrome (I am working on 34.0.x):

• Navigate to chrome://inspect/
• Check Discover USB Devices
• Plug in your phone via USB. A popup should spawn asking for permission to connect to your computer. Accept it.

There will now be an item on the chrome://inspect/ pages for your phone, and you can click inspect. Dev tools will spawn and voila!

I had this problem even after setting the config properly. git config

My scenario was issuing git command through supervisor (in Linux). On further debugging, supervisor was not reading the git config from home folder. Hence, I had to set the environment HOME variable in the supervisor config so that it can locate the git config correctly. It's strange that supervisor was not able to locate the git config just from the username configured in supervisor's config (/etc/supervisor/conf.d).

You should try this (test, works at least in Firefox):

html2canvas(document.body,{
   onrendered:function(canvas){
      document.body.appendChild(canvas);
   }
});

Im running these lines of code to get the full browser screen (only the visible screen, not the hole site):

var w=window, d=document, e=d.documentElement, g=d.getElementsByTagName('body')[0];
var y=w.innerHeight||e.clientHeight||g.clientHeight;

html2canvas(document.body,{
   height:y,
   onrendered:function(canvas){
      var img = canvas.toDataURL();
   }
});

Windows dll error 126 can have many root causes. The most useful methods I have found to debug this are:

1. Use dependency walker to look for any obvious problems (which you have already done)
2. Use the sysinternals utility Process Monitor http://technet.microsoft.com/en-us/sysinternals/bb896645 from Microsoft to trace all file access while your dll is trying to load. With this utility, you will see everything that that dll is trying to pull in and usually the problem can be determined from there.

Intent intent = new Intent(getApplicationContext(),SomeClass.class);
intent.putExtra("value",all_thumbs);
startActivity(intent);

In SomeClass.java

Bundle b = getIntent().getExtras();
if(b != null)
thumbs = (List<Thumbnail>) b.getSerializable("value");

Responsive meta tag

To ensure proper rendering and touch zooming for all devices, add the responsive viewport meta tag to your <head>.

<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">

I'm consciously writing this answer to an old question with this in mind, because the other answers didn't help me.

I got the Illegal Instruction: 4 while running the binary on the same system I had compiled it on, so -mmacosx-version-min didn't help.

I was using gcc in Code Blocks 16 on Mac OS X 10.11.

However, turning off all of Code Blocks' compiler flags for optimization worked. So look at all the flags Code Blocks set (right-click on the Project -> "Build Properties") and turn off all the flags you are sure you don't need, especially -s and the -Oflags for optimization. That did it for me.

Solution 1: override onSaveInstanceState() and remove the super call in it.

@Override
public void onSaveInstanceState(Bundle outState) {
}

Solution 2: override onSaveInstanceState() and remove your fragment before the super call

@Override
public void onSaveInstanceState(Bundle outState) {
     // TODO: Add code to remove fragment here
     super.onSaveInstanceState(outState);
}

The problem is that what you are trying to do shouldn't be done. You shouldn't be inflating fragments inside other fragments. From Android's documentation:

Note: You cannot inflate a layout into a fragment when that layout includes a <fragment>. Nested fragments are only supported when added to a fragment dynamically.

While you may be able to accomplish the task with the hacks presented here, I highly suggest you don't do it. Its impossible to be sure that these hacks will handle what each new Android OS does when you try to inflate a layout for a fragment containing another fragment.

The only Android-supported way to add a fragment to another fragment is via a transaction from the child fragment manager.

Simply change your XML layout into an empty container (add an ID if needed):

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/mapFragmentContainer"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >
</LinearLayout>

Then in the Fragment onViewCreated(View view, @Nullable Bundle savedInstanceState) method:

@Override
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
    FragmentManager fm = getChildFragmentManager();
    SupportMapFragment mapFragment = (SupportMapFragment) fm.findFragmentByTag("mapFragment");
    if (mapFragment == null) {
        mapFragment = new SupportMapFragment();
        FragmentTransaction ft = fm.beginTransaction();
        ft.add(R.id.mapFragmentContainer, mapFragment, "mapFragment");
        ft.commit();
        fm.executePendingTransactions();
    }
    mapFragment.getMapAsync(callback);
}

When you extend indirectly JpaRepository ( KassaRepository extends BaseRepository that extends JpaRepository) then you have to annotate BaseRepository with @NoRepositoryBean :

@NoRepositoryBean
public interface BaseRepository<T extends ModelBase> extends JpaRepository<T, Long> {
    T findById(long id);
}

To sum up: UUid is used to uniquely identify applications. Each application has a unique UUid

So, use the same UUid for each device

If you really want to check for all those special characters, it's easier to use a regular expression:

var str = $('#Search').val();
if(/^[a-zA-Z0-9- ]*$/.test(str) == false) {
    alert('Your search string contains illegal characters.');
}

The above will only allow strings consisting entirely of characters on the ranges a-z, A-Z, 0-9, plus the hyphen an space characters. A string containing any other character will cause the alert.

You may want to look at Tibbo VSPDL for creating a linux virtual serial port using a Kernel driver -- it seems pretty new, and is available for download right now (beta version). Not sure about the license at this point, or whether they want to make it available commercially only in the future.

There are other commercial alternatives, such as http://www.ttyredirector.com/.

In Open Source, Remserial (GPL) may also do what you want, using Unix PTY's. It transmits the serial data in "raw form" to a network socket; STTY-like setup of terminal parameters must be done when creating the port, changing them later like described in RFC 2217 does not seem to be supported. You should be able to run two remserial instances to create a virtual nullmodem like com0com, except that you'll need to set up port speed etc in advance.

Socat (also GPL) is like an extended variant of Remserial with many many more options, including a "PTY" method for redirecting the PTY to something else, which can be another instance of Socat. For Unit tets, socat is likely nicer than remserial because you can directly cat files into the PTY. See the PTY example on the manpage. A patch exists under "contrib" to provide RFC2217 support for negotiating serial line settings.

Here is a simple threading example for Android. It's very basic but it should help you to get a perspective.

Android code - Main.java

package test12.tt;

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class Test12Activity extends Activity {

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        final TextView txt1 = (TextView) findViewById(R.id.sm);

        new Thread(new Runnable() { 
            public void run(){        
            txt1.setText("Thread!!");
            }
        }).start();

    }    
}

Android application xml - main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <TextView  
    android:id = "@+id/sm"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/hello"/>

</LinearLayout>

def find_dog(new_ls):
    splt = new_ls.split()
    if 'dog' in splt:
        print("True")
    else:
        print('False')


find_dog("Is there a dog here?")

Structs can have functions just like classes. The only difference is that they are public by default:

struct A {
    void f() {}
};

Additionally, structs can also have constructors and destructors.

struct A {
    A() : x(5) {}
    ~A() {}

    private: int x;
};

I'd use <article> for a text block that is totally unrelated to the other blocks on the page. <section>, on the other hand, would be a divider to separate a document which have are related to each other.

Now, i'm not sure what you have in your videos, newsfeed etc, but here's an example (there's no REAL right or wrong, just a guideline of how I use these tags):

<article>
    <h1>People</h1>
    <p>text about people</p>
    <section>
        <h1>fat people</h1>
        <p>text about fat people</p>
    </section>
    <section>
        <h1>skinny people</p>
        <p>text about skinny people</p>
    </section>
</article>
<article>
    <h1>Cars</h1>
    <p>text about cars</p>
    <section>
        <h1>Fast Cars</h1>
        <p>text about fast cars</p>
    </section>
</article>

As you can see, the sections are still relevant to each other, but as long as they're inside a block that groups them. Sections DONT have to be inside articles. They can be in the body of a document, but i use sections in the body, when the whole document is one article.

e.g.

<body>
    <h1>Cars</h1>
    <p>text about cars</p>
    <section>
        <h1>Fast Cars</h1>
        <p>text about fast cars</p>
    </section>
</body>

Hope this makes sense.

The error you quote has nothing to do with pg_hba.conf; it's failing to connect, not failing to authorize the connection.

Do what the error message says:

Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections

You haven't shown the command that produces the error. Assuming you're connecting on localhost port 5432 (the defaults for a standard PostgreSQL install), then either:

• PostgreSQL isn't running

• PostgreSQL isn't listening for TCP/IP connections (listen_addresses in postgresql.conf)

• PostgreSQL is only listening on IPv4 (0.0.0.0 or 127.0.0.1) and you're connecting on IPv6 (::1) or vice versa. This seems to be an issue on some older Mac OS X versions that have weird IPv6 socket behaviour, and on some older Windows versions.

• PostgreSQL is listening on a different port to the one you're connecting on

• (unlikely) there's an iptables rule blocking loopback connections

(If you are not connecting on localhost, it may also be a network firewall that's blocking TCP/IP connections, but I'm guessing you're using the defaults since you didn't say).

So ... check those:

• ps -f -u postgres should list postgres processes

• sudo lsof -n -u postgres |grep LISTEN or sudo netstat -ltnp | grep postgres should show the TCP/IP addresses and ports PostgreSQL is listening on

BTW, I think you must be on an old version. On my 9.3 install, the error is rather more detailed:

$ psql -h localhost -p 12345
psql: could not connect to server: Connection refused
        Is the server running on host "localhost" (::1) and accepting
        TCP/IP connections on port 12345?

to get dynamic height based on browser window. Use vh instead of %

e.g: pass following height: 100vh; to the specific div

Yes, but not with that version of the constructor. You can do this:

>>> dict([(1, 2), (3, 4)])
{1: 2, 3: 4}

There are several different ways to make a dict. As documented, "providing keyword arguments [...] only works for keys that are valid Python identifiers."

Just try

var file = $("#uploadedfile").prop("files")[0];
var fileName = file.name;
var fileSize = file.size;
alert("Uploading: "+fileName+" @ "+fileSize+"bytes");

It worked for me

Do everything suggested by ziesemer.

You may also want to remove from the registry:

HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI\<any Ora* drivers> keys     

HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI\ODBC Drivers<any Ora* driver> values

So they no longer appear in the "ODBC Drivers that are installed on your system" in ODBC Data Source Administrator

for Xcode 5:

View->Debug Area->Activate Console

shift + cmd + c

There is no subquery needed with this statement, which is better written as

select u.* 
from Users u, CompanyRolesToUsers c
where u.Id = c.UserId        --join just specified here, perfectly fine
and u.lastname like '%fra%'
and c.CompanyRoleId in (2,3,4)

or

select u.* 
from Users u inner join CompanyRolesToUsers c
             on u.Id = c.UserId    --explicit "join" statement, no diff from above, just preference
where u.lastname like '%fra%'
  and c.CompanyRoleId in (2,3,4)

That being said, in LINQ it would be

from u in Users
from c in CompanyRolesToUsers 
where u.Id == c.UserId &&
      u.LastName.Contains("fra") &&
      selectedRoles.Contains(c.CompanyRoleId)
select u

or

from u in Users
join c in CompanyRolesToUsers 
       on u.Id equals c.UserId
where u.LastName.Contains("fra") &&
      selectedRoles.Contains(c.CompanyRoleId)
select u

Which again, are both respectable ways to represent this. I prefer the explicit "join" syntax in both cases myself, but there it is...

I had the same issue after installing the java-1.8.0-openjdk package on an AWS Linux AMI. The incorrect assumption I made, was that because the file ended in openjdk it would be the jdk version. This is not the case.

The openjdk install page explains everything clearly.

The java-1.8.0-openjdk package contains just the Java Runtime Environment. If you want to develop Java programs then install the java-1.8.0-openjdk-devel package.

If you've already installed the java-1.8.0-openjdk package, just leave it and the JAVA_HOME value if it's working for the JRE and install the java-1.8.0-openjdk-devel package using yum install java-1.8.0-openjdk-devel -y.

Joda-Time

I think you can use Joda-Time to do this. Take a look at the DateTime class and its getMillisOfSecond method. Something like

int ms = new DateTime().getMillisOfSecond() ;

They're examples provided by the Android team, if you've already loaded Samples, you can import Home screen replacement sample by following these steps.

File > New > Other >Android > Android Sample Project > Android x.x > Home > Finish

But if you do not have samples loaded, then download it using the below steps

Windows > Android SDK Manager > chooses "Sample for SDK" for SDK you need it > Install package > Accept License > Install

Guid.NewGuid() creates a new UUID using an algorithm that is designed to make collisions very, very unlikely.

new Guid() creates a UUID that is all-zeros.

Generally you would prefer the former, because that's the point of a UUID (unless you're receiving it from somewhere else of course).

There are cases where you do indeed want an all-zero UUID, but in this case Guid.Empty or default(Guid) is clearer about your intent, and there's less chance of someone reading it expecting a unique value had been created.

In all, new Guid() isn't that useful due to this lack of clarity, but it's not possible to have a value-type that doesn't have a parameterless constructor that returns an all-zeros-and-nulls value.

Edit: Actually, it is possible to have a parameterless constructor on a value type that doesn't set everything to zero and null, but you can't do it in C#, and the rules about when it will be called and when there will just be an all-zero struct created are confusing, so it's not a good idea anyway.

You are trying to do a logarithm of something that is not positive.

Logarithms figure out the base after being given a number and the power it was raised to. log(0) means that something raised to the power of 2 is 0. An exponent can never result in 0*, which means that log(0) has no answer, thus throwing the math domain error

*Note: 0^0 can result in 0, but can also result in 1 at the same time. This problem is heavily argued over.

    private void BindDataBInfo()
    {
        System.Web.HttpBrowserCapabilities browser = Request.Browser;
        Literal1.Text = "<table border=\"1\" cellspacing=\"3\" cellpadding=\"2\">";
        foreach (string key in browser.Capabilities.Keys)
        {
            Literal1.Text += "<tr><td>" + key + "</td><td>" + browser[key] + "</tr>";
        }
        Literal1.Text += "</table>";
        browser = null;
    }

You can do something like this:

function writeFile(i){
    var i = i || 0;
    var fileName = 'a_' + i + '.jpg';
    fs.exists(fileName, function (exists) {
        if(exists){
            writeFile(++i);
        } else {
            fs.writeFile(fileName);
        }
    });
}

Following steps worked for me: 1. Goto Project -> Clean. 2. Delete your previous AVD and create a new one.

You did it the wrong way around. You are meant to reset first, to unstage the file, then checkout, to revert local changes.

Try this:

$ git reset foo/bar.txt
$ git checkout foo/bar.txt

After writing

header('HTTP/1.0 404 Not Found');

add one more header for any inexisting page on your site. It works, for sure.

header("Location: http://yoursite/nowhere");
die;

Instead of dtAll = dtOne.Copy(); in Jeromy Irvine's answer you can start with an empty DataTable and merge one-by-one iteratively:

dtAll = new DataTable();
...
dtAll.Merge(dtOne);
dtAll.Merge(dtTwo);
dtAll.Merge(dtThree);
...

and so on.

This technique is useful in a loop where you want to iteratively merge data tables:

DataTable dtAllCountries = new DataTable();

foreach(String strCountry in listCountries)
{
    DataTable dtCountry = getData(strCountry); //Some function that returns a data table
    dtAllCountries.Merge(dtCountry);
}

An alternative solution for preventing functions to change the user par. You can set the default parameters early on the function, so that the graphical parameters and layout will not be changed during the function execution. See ?on.exit for further details.

on.exit(layout(1))
opar<-par(no.readonly=TRUE)
on.exit(par(opar),add=TRUE,after=FALSE)

this works for me

<input ID="TIPO_INST-0" Name="TIPO_INST" Type="Radio" value="UNAM" onchange="convenio_unam();">UNAM

<script type="text/javascript">
            function convenio_unam(){
                if(this.document.getElementById('TIPO_INST-0').checked){
                    $("#convenio_unam").hide();
                }else{
                    $("#convenio_unam").show(); 
                }                               
            }
</script>

I had similar problem, I had a list and I have to build a SQL script based on template (that contained @INPUT@ as element to replace):

for i in LIST 
do
    awk "sub(/\@INPUT\@/,\"${i}\");" template.sql >> output
done

You have put double slash \\ for the entire absolute path to achieve this Example:- D:\\images\\Lighthouse.jpg

Steps - use sendkeys for the button having browse option(The button which will open your window box to select files) - Now click on the button which is going to upload you file

driver.findElement(By.xpath("//input[@id='files']")).sendKeys("D:\\images\\Lighthouse.jpg");  
Thread.sleep(5000);
driver.findElement(By.xpath("//button[@id='Upload']")).click();

To see which options have been set on a jQuery UI button use:

$("#deliveryNext").button('option')

To check if it's disabled you can use:

$("#deliveryNext").button('option', 'disabled')

Unfortunately, if the button hasn't been explicitly enabled or disabled before, the above call will just return the button object itself so you'll need to first check to see if the options object contains the 'disabled' property.

So to determine if a button is disabled you can do it like this:

$("#deliveryNext").button('option').disabled != undefined && $("#deliveryNext").button('option', 'disabled')

I'm not sure what server side technology you are using but try using a json array. A couple of options for you to try:

  "lastName": "jay"
 },

There is a known problem with Java and glibc >= 2.10 (includes Ubuntu >= 10.04, RHEL >= 6).

The cure is to set this env. variable:

export MALLOC_ARENA_MAX=4

If you are running Tomcat, you can add this to TOMCAT_HOME/bin/setenv.sh file.

For Docker, add this to Dockerfile

ENV MALLOC_ARENA_MAX=4

There is an IBM article about setting MALLOC_ARENA_MAX https://www.ibm.com/developerworks/community/blogs/kevgrig/entry/linux_glibc_2_10_rhel_6_malloc_may_show_excessive_virtual_memory_usage?lang=en

This blog post says

resident memory has been known to creep in a manner similar to a memory leak or memory fragmentation.

There is also an open JDK bug JDK-8193521 "glibc wastes memory with default configuration"

search for MALLOC_ARENA_MAX on Google or SO for more references.

You might want to tune also other malloc options to optimize for low fragmentation of allocated memory:

# tune glibc memory allocation, optimize for low fragmentation
# limit the number of arenas
export MALLOC_ARENA_MAX=2
# disable dynamic mmap threshold, see M_MMAP_THRESHOLD in "man mallopt"
export MALLOC_MMAP_THRESHOLD_=131072
export MALLOC_TRIM_THRESHOLD_=131072
export MALLOC_TOP_PAD_=131072
export MALLOC_MMAP_MAX_=65536

isFakeGPSInstalled = Utils.isPackageInstalled(Utils.PACKAGE_ID_FAKE_GPS, this.getPackageManager());

//method to check package installed true/false

  public static boolean isPackageInstalled(String packageName, PackageManager packageManager) {
    boolean found = true;
    try {
      packageManager.getPackageInfo(packageName, 0);
    } catch (PackageManager.NameNotFoundException e) {
      found = false;
    }

    return found;
  }

Double click and install the production certificate in your key chain. This might resolve the issue.

You can also check out github.com/wushilin/stream

It is a lazy stream like concept of java.util.stream.

// It doesn't really allocate the 10 elements.
stream1 := stream.Range(0, 10)

// Print each element.
stream1.Each(print)

// Add 3 to each element, but it is a lazy add.
// You only add when consume the stream
stream2 := stream1.Map(func(i int) int {
    return i + 3
})

// Well, this consumes the stream => return sum of stream2.
stream2.Reduce(func(i, j int) int {
    return i + j
})

// Create stream with 5 elements
stream3 := stream.Of(1, 2, 3, 4, 5)

// Create stream from array
stream4 := stream.FromArray(arrayInput)

// Filter stream3, keep only elements that is bigger than 2,
// and return the Sum, which is 12
stream3.Filter(func(i int) bool {
    return i > 2
}).Sum()

Hope this helps

This could also occur if you refer to a variable in the data.frame that doesn't exist. For example, recently I forgot to tell ddply to summarize by one of my variables that I used in geom_line to specify line color. Then, ggplot didn't know where to find the variable I hadn't created in the summary table, and I got this error.

Your error shows you are not compiling file with the definition of the insert function. Update your command to include the file which contains the definition of that function and it should work.

If you need something like:

  ¦ A                              ¦ B
--+--------------------------------+---
1 ¦ #My comment, something else    ¦
2 ¦ 1                              ¦ 2

Your CSV may contain the following lines:

"#My comment, something else"
1,2

Pay close attention at the 'quotes' in the first line.

When converting your text to columns using the Excel wizard, remember checking the 'Treat consecutive delimiters as one', setting it to use 'quotes' as delimiter.

Thus, Excel will split the text at the commas, keeping the 'comment' line as a single column value (and it will remove the quotes).

word-wrap: break-word; 

add this to your container that should do the trick

I find this Angular How-to: Editable Config Files from Microsoft Dev blogs being the best solution. You can configure dev build settings or prod build settings.

SHOULD be unique does not mean MUST be unique. However, as stated, some parsers would fail and others would just use the last value parsed. However, if the spec was cleaned up a little to allow for duplicates then I could see a use where you may have an event handler which is transforming the JSON to HTML or some other format... In such cases it would be perfectly valid to parse the JSON and create another document format...

[
  "div":
  {
    "p": "hello",
    "p": "universe"
  },
  "div":
  {
    "h1": "Heading 1",
    "p": "another paragraph"
  }
]

could then easily parse to html for example:

<body>
 <div>
  <p>hello</p>
  <p>universe</p>
 </div>
 <div>
  <h1>Heading 1</h1>
  <p>another paragraph</p>
 </div>
</body>

I can see the reasoning behind the question but as it stands... I wouldn't trust it.

What you have is a valid ADO.NET connection string - but it's NOT a valid Entity Framework connection string.

The EF connection string would look something like this:

<connectionStrings> 
  <add name="NorthwindEntities" connectionString=
     "metadata=.\Northwind.csdl|.\Northwind.ssdl|.\Northwind.msl;
      provider=System.Data.SqlClient;
      provider connection string=&quot;Data Source=SERVER\SQL2000;Initial Catalog=Northwind;Integrated Security=True;MultipleActiveResultSets=False&quot;" 
      providerName="System.Data.EntityClient" /> 
</connectionStrings>

You're missing all the metadata= and providerName= elements in your EF connection string...... you basically only have what's contained in the provider connection string part.

Using the EDMX designer should create a valid EF connection string for you, in your web.config or app.config.

Marc

UPDATE: OK, I understand what you're trying to do: you need a second "ADO.NET" connection string just for ASP.NET user / membership database. Your string is OK, but the providerName is wrong - it would have to be "System.Data.SqlClient" - this connection doesn't use ENtity Framework - don't specify the "EntityClient" for it then!

<add name="ASPNETMembership" 
     connectionString="Data Source=MONTGOMERY-DEV\SQLEXPRESS;Initial Catalog=ASPNETDB;Integrated Security=True;" 
     providerName="System.Data.SqlClient" />

If you specify providerName=System.Data.EntityClient ==> Entity Framework connection string (with the metadata= and everything).

If you need and specify providerName=System.Data.SqlClient ==> straight ADO.NET SQL Server connection string without all the EF additions

If You are on another branch, You need first "check to this commit" for commit you want to delete, and only then "reset current branch to this commit" choosing previous wright commit, will work.

why not just backup the data before your work with it, then restore when you want it to be refreshed?

if you must generate inserts try: http://vyaskn.tripod.com/code.htm#inserts

function checkLectureStatus($lectureName) {
  global $con;
  $lectureName = mysql_real_escape_string($lectureName);
  $sql = "SELECT 1 FROM preditors_assigned WHERE lecture_name='$lectureName'";
  $result = mysql_query($sql) or trigger_error(mysql_error()." ".$sql);
  if (mysql_fetch_row($result)) {
    return 'Assigned';
  }
  return 'Available';
}

however you have to use some abstraction library for the database access.
the code would become

function checkLectureStatus($lectureName) {
  $res = db::getOne("SELECT 1 FROM preditors_assigned WHERE lecture_name=?",$lectureName);
  if($res) {
    return 'Assigned';
  }
  return 'Available';
}

We can do it without the -f Go template syntax:

docker inspect <CONTAINER_ID> | jq .[] | jq .Mounts[]

The first jq operation jq .[] strips the object {} wrapper.

The second jq operation will return all the Mount items.

If you want to see only fatal runtime errors:

php_value display_errors on
php_value error_reporting 4

If the ticked answer is working fine for you but it shows nothing when the search text is empty. Here is the solution:

        if(constraint.length() == 0)
        {

            if (filterableString.toLowerCase().contains(filterString)) {
                nlist.add(filterableString);
            }
        }
        
        results.values = nlist;
        results.count = nlist.size();

        return results;

    protected void publishResults(CharSequence constraint, FilterResults results) {
        filteredData = (ArrayList<String>) results.values;
        notifyDataSetChanged();
      }

   }

For any query comment below

This worked for me:

@Override
protected void onStart() {
    super.onStart();
    mySpinner.setSelection(position);
}

It's similar to @sberezin's solution but calling setSelection() in onStart().

This solution helped me to skip the number of lines specified by the linetostart variable. You get the index (int) and the line (string) if you want to keep track of those too. In your case, you substitute linetostart with 18, or assign 18 to linetostart variable.

f = open("file.txt", 'r')
for i, line in enumerate(f, linetostart):
    #Your code

I have been reading through most of the answers here and many of the comments, and I didn't see any reference to the one instance that I could think of where i++ is more efficient than ++i (and perhaps surprisingly --i was more efficient than i--). That is for C compilers for the DEC PDP-11!

The PDP-11 had assembly instructions for pre-decrement of a register and post-increment, but not the other way around. The instructions allowed any "general-purpose" register to be used as a stack pointer. So if you used something like *(i++) it could be compiled into a single assembly instruction, while *(++i) could not.

This is obviously a very esoteric example, but it does provide the exception where post-increment is more efficient(or I should say was, since there isn't much demand for PDP-11 C code these days).

You can add a style to your styles.xml,

<style name="ToolbarTheme" parent="@style/ThemeOverlay.AppCompat.ActionBar">
  <!-- Customize color of navigation drawer icon and back arrow --> 
  <item name="colorControlNormal">@color/toolbar_color_control_normal</item>
</style>

and add this as theme to your toolbar in toolbar layout.xml using app:theme, check below

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:minHeight="?attr/actionBarSize"
    android:background="?attr/colorPrimary"
    app:theme="@style/ToolbarTheme" >
</android.support.v7.widget.Toolbar>

A very simple answer if you say you don't care which address is used.

SELECT
    CName, MIN(AddressLine)
FROM
    MyTable
GROUP BY
    CName

If you want the first according to, say, an "inserted" column then it's a different query

SELECT
    M.CName, M.AddressLine,
FROM
    (
    SELECT
        CName, MIN(Inserted) AS First
    FROM
        MyTable
    GROUP BY
        CName
    ) foo
    JOIN
    MyTable M ON foo.CName = M.CName AND foo.First = M.Inserted

Use a secure URL for your initial connection, i.e. instead of "http://" use "https://". If the WebSocket transport is chosen, then Socket.IO should automatically use "wss://" (SSL) for the WebSocket connection too.

Update:

You can also try creating the connection using the 'secure' option:

var socket = io.connect('https://localhost', {secure: true});

How about adding one extra decimal that is to be rounded and then discarded:

var d = 0.241534545765;
var result1 = d.ToString("0.###%");

var result2 = result1.Remove(result1.Length - 1);

If you would like to setup the search facility inside your Fragment, just add these few lines:

Step 1 - Add the search field to you toolbar:

<item
    android:id="@+id/action_search"
    android:icon="@android:drawable/ic_menu_search"
    app:showAsAction="always|collapseActionView"
    app:actionViewClass="android.support.v7.widget.SearchView"
    android:title="Search"/>

Step 2 - Add the logic to your onCreateOptionsMenu()

import android.support.v7.widget.SearchView; // not the default !

@Override
public boolean onCreateOptionsMenu( Menu menu) {
    getMenuInflater().inflate( R.menu.main, menu);

    MenuItem myActionMenuItem = menu.findItem( R.id.action_search);
    searchView = (SearchView) myActionMenuItem.getActionView();
    searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
        @Override
        public boolean onQueryTextSubmit(String query) {
            // Toast like print
            UserFeedback.show( "SearchOnQueryTextSubmit: " + query);
            if( ! searchView.isIconified()) {
                searchView.setIconified(true);
            }
            myActionMenuItem.collapseActionView();
            return false;
        }
        @Override
        public boolean onQueryTextChange(String s) {
            // UserFeedback.show( "SearchOnQueryTextChanged: " + s);
            return false;
        }
    });
    return true;
}

In case anyone else runs into this problem, I was able to get it working like this:

var path = require('path');
// ...
resolve: {
  root: [path.resolve(__dirname, 'src'), path.resolve(__dirname, 'node_modules')],
  extensions: ['', '.js']
};

where my directory structure is:

.
+-- dist
+-- node_modules
+-- package.json
+-- README.md
+-- src
¦   +-- components
¦   +-- index.html
¦   +-- main.js
¦   +-- styles
+-- webpack.config.js

Then from anywhere in the src directory I can call:

import MyComponent from 'components/MyComponent';

If you are using macOS {mine 'High Sierra'} and Installed XAMPP

You can find mysql data files;

Go to : /Applications/XAMPP/xamppfiles/var/mysql/

You can use string.punctuation and any function like this

import string
invalidChars = set(string.punctuation.replace("_", ""))
if any(char in invalidChars for char in word):
    print "Invalid"
else:
    print "Valid"

With this line

invalidChars = set(string.punctuation.replace("_", ""))

we are preparing a list of punctuation characters which are not allowed. As you want _ to be allowed, we are removing _ from the list and preparing new set as invalidChars. Because lookups are faster in sets.

any function will return True if atleast one of the characters is in invalidChars.

Edit: As asked in the comments, this is the regular expression solution. Regular expression taken from https://stackoverflow.com/a/336220/1903116

word = "Welcome"
import re
print "Valid" if re.match("^[a-zA-Z0-9_]*$", word) else "Invalid"

Solution for Ruby 1.8 when you have an arbitrary DateTime object:

1.8.7-p374 :001 > require 'date'
 => true 
1.8.7-p374 :002 > DateTime.new(2012, 1, 15).strftime('%s')
 => "1326585600"

You can specify the orientation of an activity in the manifest. See here.

<activity android:allowTaskReparenting=["true" | "false"]
...
          android:screenOrientation=["unspecified" | "user" | "behind" |
                                     "landscape" | "portrait" |
                                     "sensor" | "nosensor"]
...
                                       "adjustResize", "adjustPan"] >  

For PLSQL version 9.0.0.1601

1. From the context menu of the Table, choose "Edit Data"
2. Insert or edit the data
3. Post change

Your BlockID function uses the undefined variable images, which will lead to an error. Also, you should not use an Array here - JavaScripts key-value-maps are plain objects:

function BlockID() {
    return {
        "s": "Images/Block_01.png",
        "g": "Images/Block_02.png",
        "C": "Images/Block_03.png",
        "d": "Images/Block_04.png"
    };
}

RouterModule.forRoot([
      { path: 'welcome', component: WelcomeComponent },
      { path: '', redirectTo: 'welcome', pathMatch: 'full' },
      { path: '**', component: 'pageNotFoundComponent' }
    ])

Case 1 pathMatch:'full': In this case, when app is launched on localhost:4200 (or some server) the default page will be welcome screen, since the url will be https://localhost:4200/

If https://localhost:4200/gibberish this will redirect to pageNotFound screen because of path:'**' wildcard

Case 2 pathMatch:'prefix':

If the routes have { path: '', redirectTo: 'welcome', pathMatch: 'prefix' }, now this will never reach the wildcard route since every url would match path:'' defined.

Like @g-eorge mention, you can make it like this:

module.config(['$routeProvider', function($routeProvider) {
$routeProvider.
  when('/users/:userId?', {templateUrl: 'template.tpl.html', controller: myCtrl})
}]);

You can also make as much as u need optional parameters.

You can take advantage of the fact that span is an inline element

span{
     word-spacing:10px;
}

However, this solution will break if you have more than one word of text in your span

Microsoft SQL Server's INTERSECT "returns any distinct values that are returned by both the query on the left and right sides of the INTERSECT operand" This is different from a standard INNER JOIN or WHERE EXISTS query.

SQL Server

CREATE TABLE table_a (
    id INT PRIMARY KEY,
    value VARCHAR(255)
);

CREATE TABLE table_b (
    id INT PRIMARY KEY,
    value VARCHAR(255)
);

INSERT INTO table_a VALUES (1, 'A'), (2, 'B'), (3, 'B');
INSERT INTO table_b VALUES (1, 'B');

SELECT value FROM table_a
INTERSECT
SELECT value FROM table_b

value
-----
B

(1 rows affected)

MySQL

CREATE TABLE `table_a` (
  `id` INT NOT NULL AUTO_INCREMENT,
  `value` varchar(255),
  PRIMARY KEY (`id`)
) ENGINE=InnoDB;

CREATE TABLE `table_b` LIKE `table_a`;

INSERT INTO table_a VALUES (1, 'A'), (2, 'B'), (3, 'B');
INSERT INTO table_b VALUES (1, 'B');

SELECT value FROM table_a
INNER JOIN table_b
USING (value);

+-------+
| value |
+-------+
| B     |
| B     |
+-------+
2 rows in set (0.00 sec)

SELECT value FROM table_a
WHERE (value) IN
(SELECT value FROM table_b);

+-------+
| value |
+-------+
| B     |
| B     |
+-------+

With this particular question, the id column is involved, so duplicate values will not be returned, but for the sake of completeness, here's a MySQL alternative using INNER JOIN and DISTINCT:

SELECT DISTINCT value FROM table_a
INNER JOIN table_b
USING (value);

+-------+
| value |
+-------+
| B     |
+-------+

And another example using WHERE ... IN and DISTINCT:

SELECT DISTINCT value FROM table_a
WHERE (value) IN
(SELECT value FROM table_b);

+-------+
| value |
+-------+
| B     |
+-------+

If you don't mind using PHP's DateTime class, which has been available since PHP 5.2.0, then there are several scenarios that might fit your situation:

1. If you have a $givenDt DateTime object that you want to convert to UTC then this will convert it to UTC:

   $givenDt->setTimezone(new DateTimeZone('UTC'));
   

2. If you need the original $givenDt later, you might alternatively want to clone the given DateTime object before conversion of the cloned object:

   $utcDt = clone $givenDt;
   $utcDt->setTimezone(new DateTimeZone('UTC'));
   

3. If you only have a datetime string, e.g. $givenStr = '2018-12-17 10:47:12', then you first create a datetime object, and then convert it. Note this assumes that $givenStr is in PHP's configured timezone.

   $utcDt = (new DateTime($givenStr))->setTimezone(new DateTimeZone('UTC'));
   

4. If the given datetime string is in some timezone different from the one in your PHP configuration, then create the datetime object by supplying the correct timezone (see the list of timezones PHP supports). In this example we assume the local timezone in Amsterdam:

   $givenDt = new DateTime($givenStr, new DateTimeZone('Europe/Amsterdam'));
   $givenDt->setTimezone(new DateTimeZone('UTC'));
   

Thanks for your answers. I missed that my data is stored in a List<String> which is passed to the tested method. The mistake was that I put the string into the first element of the ArrayList. That's why I thought the String consists of just one single line, because the debugger showed me only one entry.

If there is someone interested in achieve the @Pedro Silva solution in JS, I just ported this same solution for it:

const getBase64Size = (base64) => {
  let padding = base64.length
    ? getBase64Padding(base64)
    : 0
  return ((Math.ceil(base64.length / 4) * 3 ) - padding) / 1000
}

const getBase64Padding = (base64) => {
  return endsWith(base64, '==')
    ? 2
    : 1
}

const endsWith = (str, end) => {
  let charsFromEnd = end.length
  let extractedEnd = str.slice(-charsFromEnd)
  return extractedEnd === end
}

I think what you're looking for is generally known as an "off-canvas" layout. Here is the standard off-canvas example from the official Bootstrap docs: http://getbootstrap.com/examples/offcanvas/

The "official" example uses a right-side sidebar the toggle off and on separately from the top navbar menu. I also found these off-canvas variations that slide in from the left and may be closer to what you're looking for..

Update: Sep 2019

As a few people have mentioned, the parameters in paramMap should be accessed using the common MapAPI:

To get a snapshot of the params, when you don't care that they may change:

this.bankName = this.route.snapshot.paramMap.get('bank');

To subscribe and be alerted to changes in the parameter values (typically as a result of the router's navigation)

this.route.paramMap.subscribe( paramMap => {
    this.bankName = paramMap.get('bank');
})

Update: Aug 2017

Since Angular 4, params have been deprecated in favor of the new interface paramMap. The code for the problem above should work if you simply substitute one for the other.

Original Answer

If you inject ActivatedRoute in your component, you'll be able to extract the route parameters

    import {ActivatedRoute} from '@angular/router';
    ...
    
    constructor(private route:ActivatedRoute){}
    bankName:string;
    
    ngOnInit(){
        // 'bank' is the name of the route parameter
        this.bankName = this.route.snapshot.params['bank'];
    }

If you expect users to navigate from bank to bank directly, without navigating to another component first, you ought to access the parameter through an observable:

    ngOnInit(){
        this.route.params.subscribe( params =>
            this.bankName = params['bank'];
        )
    }

For the docs, including the differences between the two check out this link and search for "activatedroute"

java.io.NotSerializableException can occur when you serialize an inner class instance because:

serializing such an inner class instance will result in serialization of its associated outer class instance as well

Serialization of inner classes (i.e., nested classes that are not static member classes), including local and anonymous classes, is strongly discouraged

Ref: The Serializable Interface

If you use a website and you fill out a form to submit information (your social security number for example) you want to be sure that the information is being sent to the site you think it's being sent to. So browsers were built to say, by default, 'Do not send information to a domain other than the domain being visited).

Eventually that became too limiting but the default idea still remains in browsers. Don't let the web page send information to a different domain. But this is all browser checking. Chrome and firefox, etc have built in code that says 'before send this request, we're going to check that the destination matches the page being visited'.

Postman (or CURL on the cmd line) doesn't have those built in checks. You're manually interacting with a site so you have full control over what you're sending.

A "for loop" in most, if not all, programming languages is a mechanism to run a piece of code more than once.

This code:

for i in range(5):
    print i

can be thought of working like this:

i = 0
print i
i = 1
print i
i = 2
print i
i = 3
print i
i = 4
print i

So you see, what happens is not that i gets the value 0, 1, 2, 3, 4 at the same time, but rather sequentially.

I assume that when you say "call a, it gives only 5", you mean like this:

for i in range(5):
    a=i+1
print a

this will print the last value that a was given. Every time the loop iterates, the statement a=i+1 will overwrite the last value a had with the new value.

Code basically runs sequentially, from top to bottom, and a for loop is a way to make the code go back and something again, with a different value for one of the variables.

I hope this answered your question.

There is an .Offset property on a Range class which allows you to do just what you need

ActiveCell.Offset(numRows, numCols)

follow up on a comment:

Dim newRange as Range
Set newRange = Range(ActiveCell, ActiveCell.Offset(numRows, numCols))

and you can verify by MsgBox newRange.Address

and here's how to assign this range to an array

This one Works for me with asp label control.

 function changeEmaillbl() {


         if (document.getElementById('<%=rbAgency.ClientID%>').checked = true) {
             document.getElementById('<%=lblUsername.ClientID%>').innerHTML = 'Accredited No.:';
         } 
     }

The cause of your problem is simple. So many people will run into the same problem, Because I did too and it took me hour to figure out. Just in case, someone else stumbles, The problem is in your query, your select statement is calling $dbname instead of table name. So its not found whereby returning false which is boolean. Good luck.

I was able to resolve this by adding the following to my component:

componentDidMount() {
  ReactDOM.findDOMNode(this).addEventListener('click', (event) => {
    event.stopPropagation();
  }, false);
}

I used 'live' in my project but one of my friend suggested that i should use 'on' instead of live. And when i tried to use that i experienced a problem like you had.

On my pages i create buttons table rows and many dom stuff dynamically. but when i use on the magic disappeared.

The other solutions like use it like a child just calls your functions every time on every click. But i find a way to make it happen again and here is the solution.

Write your code as:

function caller(){
    $('.ObjectYouWntToCall').on("click", function() {...magic...});
}

Call caller(); after you create your object in the page like this.

$('<dom class="ObjectYouWntToCall">bla... bla...<dom>').appendTo("#whereeveryouwant");
caller();

By this way your function is called when it is supposed to not every click on the page.

shlex has a .split() function. It differs from str.split() in that it does not preserve quotes and treats a quoted phrase as a single word:

>>> import shlex
>>> shlex.split("sudo echo 'foo && bar'")
['sudo', 'echo', 'foo && bar']

NB: it works well for Unix-like command line strings. It doesn't work for natural-language processing.

For Excel 2010 it should be UTF-8. Instruction by MS :
http://msdn.microsoft.com/en-us/library/bb507946:

"The basic document structure of a SpreadsheetML document consists of the Sheets and Sheet elements, which reference the worksheets in the Workbook. A separate XML file is created for each Worksheet. For example, the SpreadsheetML for a workbook that has two worksheets name MySheet1 and MySheet2 is located in the Workbook.xml file and is shown in the following code example.

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?> 
<workbook xmlns=http://schemas.openxmlformats.org/spreadsheetml/2006/main xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships">
    <sheets>
        <sheet name="MySheet1" sheetId="1" r:id="rId1" /> 
        <sheet name="MySheet2" sheetId="2" r:id="rId2" /> 
    </sheets>
</workbook>

The worksheet XML files contain one or more block level elements such as SheetData. sheetData represents the cell table and contains one or more Row elements. A row contains one or more Cell elements. Each cell contains a CellValue element that represents the value of the cell. For example, the SpreadsheetML for the first worksheet in a workbook, that only has the value 100 in cell A1, is located in the Sheet1.xml file and is shown in the following code example.

<?xml version="1.0" encoding="UTF-8" ?> 
<worksheet xmlns="http://schemas.openxmlformats.org/spreadsheetml/2006/main">
    <sheetData>
        <row r="1">
            <c r="A1">
                <v>100</v> 
            </c>
        </row>
    </sheetData>
</worksheet>

On Debian LINUX, I use: ps -o pid= -u username | xargs sudo kill -9.

With -o pid= the ps header is supressed, and the output is only the pid list. As far as I know, Debian shell is POSIX compliant.

Or, if you need to access the element that has that property and it does not use an id, you could go this route:

$("img").each(function () {
        if ($(this).css("float") == "left") { $(this).addClass("left"); }
        if ($(this).css("float") == "right") { $(this).addClass("right"); }
    })

I also face a situation when I needed to return a top result but also wanted to get the total rows that where matching the query. i finaly get to this solution:

   public string Format(SelectQuery selectQuery)
    {
      string result;

      if (string.IsNullOrWhiteSpace(selectQuery.WherePart))
      {
        result = string.Format(
@"
declare @maxResult  int;
set @maxResult = {0};

WITH Total AS
(
SELECT count(*) as [Count] FROM {2}
)
SELECT top (@maxResult) Total.[Count], {1} FROM Total, {2}", m_limit.To, selectQuery.SelectPart, selectQuery.FromPart);
      }
      else
      {
        result = string.Format(
@"
declare @maxResult  int;
set @maxResult = {0};

WITH Total AS
(
SELECT count(*) as [Count] FROM {2} WHERE {3}
)
SELECT top (@maxResult) Total.[Count], {1} FROM Total, {2} WHERE {3}", m_limit.To, selectQuery.SelectPart, selectQuery.FromPart, selectQuery.WherePart);
      }

      if (!string.IsNullOrWhiteSpace(selectQuery.OrderPart))
        result = string.Format("{0} ORDER BY {1}", result, selectQuery.OrderPart);

      return result;
    }

You could use substr, I guess:

$string2 = substr($string1, 0, 100);

or mb_substr for multi-byte strings:

$string2 = mb_substr($string1, 0, 100);

You could create a function wich uses this function and appends for instance '...' to indicate that it was shortened. (I guess there's allready a hundred similar replies when this is posted...)

you should add plug in to your local setting of firefox in your user home

Tortoise SVN on Windows happens to lose sync quite often with the real file status. In that case try doing an svn cleanup.

Another thing, it may also depend where your source files are located, different drive, network drive, etc. There's an option in Tortoise to allow icon overlay or not, on remote drives.

Check this out in: TortoiseSVN / Settings / Icon Overlays / Drive types

Though I don't see much point, here it is:

for i in xrange(0, len(prices)):
    exec("price%d = %s" % (i + 1, repr(prices[i])));

You might want to put the absolutely aligned div in a relatively aligned container - this way it will still be contained into the container rather than the browser window.

<div style="position: relative;background-color: blue; width: 600px; height: 800px;">    

    <div style="position: absolute; bottom: 5px; background-color: green">
    TEST (C) 2010
    </div>
</div>

On Windows, you can also use the Win32 File Namespace prefixed with \\?\ to refer to your local directories:

\\?\C:\my_dir

See this answer for description.

The same as in Eli's answer - just using a shorter form, because you can skip a lambda part here.

Creating new list:

>>> xs = ['dddd','a','bb','ccc']
>>> sorted(xs, key=len)
['a', 'bb', 'ccc', 'dddd']

In-place sorting:

>>> xs.sort(key=len)
>>> xs
['a', 'bb', 'ccc', 'dddd']

It depends upon lower_case_table_names system variable:

show variables where Variable_name='lower_case_table_names'

There are three possible values for this:

• 0 - lettercase specified in the CREATE TABLE or CREATE DATABASE statement. Name comparisons are case sensitive.
• 1 - Table names are stored in lowercase on disk and name comparisons are not case sensitive.
• 2 - lettercase specified in the CREATE TABLE or CREATE DATABASE statement, but MySQL converts them to lowercase on lookup. Name comparisons are not case sensitive.

This happen after you disable via Control Panel -> network adapters -> right click button on the virtual connection -> disable

To fix that go to Device Manager (Windows-key + x + m on windows 8, Windows-key + x then m on windows 10), then open the network adapters tree , right click button on Microsoft Hosted Network Virtual Adapter and click on enable.

Try now with the command netsh wlan start hostednetwork with admin privileges. It should work.

Note: If you don't see the network adapter with name 'Microsoft Hosted Network Virtual Adapter' try on menu -> view -> show hidden devices in the Device Manager window.

The easiest one,

$('#location').find('option:selected').attr('myTag');

Here is the method I made to transform recursively the fields of an object in a map ready to be used with a MockHttpServletRequestBuilder

public static void objectToPostParams(final String key, final Object value, final Map<String, String> map) throws IllegalAccessException {
    if ((value instanceof Number) || (value instanceof Enum) || (value instanceof String)) {
        map.put(key, value.toString());
    } else if (value instanceof Date) {
        map.put(key, new SimpleDateFormat("yyyy-MM-dd HH:mm").format((Date) value));
    } else if (value instanceof GenericDTO) {
        final Map<String, Object> fieldsMap = ReflectionUtils.getFieldsMap((GenericDTO) value);
        for (final Entry<String, Object> entry : fieldsMap.entrySet()) {
            final StringBuilder sb = new StringBuilder();
            if (!GenericValidator.isEmpty(key)) {
                sb.append(key).append('.');
            }
            sb.append(entry.getKey());
            objectToPostParams(sb.toString(), entry.getValue(), map);
        }
    } else if (value instanceof List) {
        for (int i = 0; i < ((List) value).size(); i++) {
            objectToPostParams(key + '[' + i + ']', ((List) value).get(i), map);
        }
    }
}

GenericDTO is a simple class extending Serializable

public interface GenericDTO extends Serializable {}

and here is the ReflectionUtils class

public final class ReflectionUtils {
    public static List<Field> getAllFields(final List<Field> fields, final Class<?> type) {
        if (type.getSuperclass() != null) {
            getAllFields(fields, type.getSuperclass());
        }
        // if a field is overwritten in the child class, the one in the parent is removed
        fields.addAll(Arrays.asList(type.getDeclaredFields()).stream().map(field -> {
            final Iterator<Field> iterator = fields.iterator();
            while(iterator.hasNext()){
                final Field fieldTmp = iterator.next();
                if (fieldTmp.getName().equals(field.getName())) {
                    iterator.remove();
                    break;
                }
            }
            return field;
        }).collect(Collectors.toList()));
        return fields;
    }

    public static Map<String, Object> getFieldsMap(final GenericDTO genericDTO) throws IllegalAccessException {
        final Map<String, Object> map = new HashMap<>();
        final List<Field> fields = new ArrayList<>();
        getAllFields(fields, genericDTO.getClass());
        for (final Field field : fields) {
            final boolean isFieldAccessible = field.isAccessible();
            field.setAccessible(true);
            map.put(field.getName(), field.get(genericDTO));
            field.setAccessible(isFieldAccessible);
        }
        return map;
    }
}

You can use it like

final MockHttpServletRequestBuilder post = post("/");
final Map<String, String> map = new TreeMap<>();
objectToPostParams("", genericDTO, map);
for (final Entry<String, String> entry : map.entrySet()) {
    post.param(entry.getKey(), entry.getValue());
}

I didn't tested it extensively, but it seems to work.

Here's a Swift extension for UILabel. It runs a binary search algorithm to resize the font based off the width and height of the label's bounds. Tested to work with iOS 9 and autolayout.

USAGE: Where <label> is your pre-defined UILabel that needs font resizing

<label>.fitFontForSize()

By Default, this function searches in within the range of 5pt and 300pt font sizes and sets the font to fit its text "perfectly" within the bounds (accurate within 1.0pt). You could define the parameters so that it, for example, searches between 1pt and the label's current font size accurately within 0.1pts in the following way:

<label>.fitFontForSize(1.0, maxFontSize: <label>.font.pointSize, accuracy:0.1)

Copy/Paste the following code into your file

extension UILabel {

    func fitFontForSize(var minFontSize : CGFloat = 5.0, var maxFontSize : CGFloat = 300.0, accuracy : CGFloat = 1.0) {
        assert(maxFontSize > minFontSize)
        layoutIfNeeded() // Can be removed at your own discretion
        let constrainedSize = bounds.size
        while maxFontSize - minFontSize > accuracy {
            let midFontSize : CGFloat = ((minFontSize + maxFontSize) / 2)
            font = font.fontWithSize(midFontSize)
            sizeToFit()
            let checkSize : CGSize = bounds.size
            if  checkSize.height < constrainedSize.height && checkSize.width < constrainedSize.width {
                minFontSize = midFontSize
            } else {
                maxFontSize = midFontSize
            }
        }
        font = font.fontWithSize(minFontSize)
        sizeToFit()
        layoutIfNeeded() // Can be removed at your own discretion
    }

}

NOTE: Each of the layoutIfNeeded() calls can be removed at your own discretion

Replace this :

$('#subscription_order_form').submit(function(e){
  e.preventDefault();
});

with this:

$('#subscription_order_form').on('keydown', function(e){
    if (e.which===13) e.preventDefault();
});

FIDDLE

That will prevent the form from submitting when Enter key is pressed as it prevents the default action of the key, but the form will submit normally on click.

Yes, Json.Net is what you need. You basically want to deserialize a Json string into an array of objects.

See their examples:

string myJsonString = @"{
  "Name": "Apple",
  "Expiry": "\/Date(1230375600000+1300)\/",
  "Price": 3.99,
  "Sizes": [
    "Small",
    "Medium",
    "Large"
  ]
}";

// Deserializes the string into a Product object
Product myProduct = JsonConvert.DeserializeObject<Product>(myJsonString);

The difference between Slice() and Splice() javascript build-in functions is, Slice returns removed item but did not change the original array ; like,

        // (original Array)
        let array=[1,2,3,4,5] 
        let index= array.indexOf(4)
         // index=3
        let result=array.slice(index)
        // result=4  
        // after slicing=>  array =[1,2,3,4,5]  (same as original array)

but in splice() case it affects original array; like,

         // (original Array)
        let array=[1,2,3,4,5] 
        let index= array.indexOf(4)
         // index=3
        let result=array.splice(index)
        // result=4  
        // after splicing array =[1,2,3,5]  (splicing affects original array)

You could do something using the grep command:

find . | grep -v '(dll|exe)$'

The -v flag on grep specifically means "find things that don't match this expression."

to order after the colsum :

order(colSums(people),decreasing=TRUE)

if more than 20+ columns

order(colSums(people[,c(5:25)],decreasing=TRUE) ##in case of keeping the first 4 columns remaining.

I suggest to use a container for each img p like this:

<div class="image123">
    <div style="float:left;margin-right:5px;">
        <img src="/images/tv.gif" height="200" width="200"  />
        <p style="text-align:center;">This is image 1</p>
    </div>
    <div style="float:left;margin-right:5px;">
        <img class="middle-img" src="/images/tv.gif/" height="200" width="200" />
        <p style="text-align:center;">This is image 2</p>
    </div>
    <div style="float:left;margin-right:5px;">
        <img src="/images/tv.gif/" height="200" width="200" />
        <p style="text-align:center;">This is image 3</p>
    </div>
</div>

Then apply float:left to each container. I add and 5px margin right so there is a space between each image. Also alway close your elements. Maybe in html img tag is not important to close but in XHTML is.

fiddle

Also a friendly advice. Try to avoid inline styles as much as possible. Take a look here:

html

<div class="image123">
    <div>
        <img src="/images/tv.gif" />
        <p>This is image 1</p>
    </div>
    <div>
        <img class="middle-img" src="/images/tv.gif/" />
        <p>This is image 2</p>
    </div>
    <div>
        <img src="/images/tv.gif/" />
        <p>This is image 3</p>
    </div>
</div>

css

div{
    float:left;
    margin-right:5px;
}

div > img{
   height:200px;
    width:200px;
}

p{
    text-align:center;
}

It's generally recommended that you use linked style sheets because:

• They can be cached by browsers for performance
• Generally a lot easier to maintain for a development perspective

If you want to get the week number with the year, Grant Shannon's solution using strftime works, but you need to make some corrections for the dates around january 1st. For instance, 2016-01-03 (yyyy-mm-dd) is week 53 of year 2015, not 2016. And 2018-12-31 is week 1 of 2019, not of 2018. This codes provides some examples and a solution. In column "yearweek" the years are sometimes wrong, in "yearweek2" they are corrected (rows 2 and 5).

DOUBLE columns are not the same as DECIMAL columns, and you will get in trouble if you use DOUBLE columns for financial data.

DOUBLE is actually just a double precision (64 bit instead of 32 bit) version of FLOAT. Floating point numbers are approximate representations of real numbers and they are not exact. In fact, simple numbers like 0.01 do not have an exact representation in FLOAT or DOUBLE types.

DECIMAL columns are exact representations, but they take up a lot more space for a much smaller range of possible numbers. To create a column capable of holding values from 0.0001 to 99.9999 like you asked you would need the following statement

CREATE TABLE your_table
(
    your_column DECIMAL(6,4) NOT NULL
);

The column definition follows the format DECIMAL(M, D) where M is the maximum number of digits (the precision) and D is the number of digits to the right of the decimal point (the scale).

This means that the previous command creates a column that accepts values from -99.9999 to 99.9999. You may also create an UNSIGNED DECIMAL column, ranging from 0.0000 to 99.9999.

For more information on MySQL DECIMAL the official docs are always a great resource.

Bear in mind that all of this information is true for versions of MySQL 5.0.3 and greater. If you are using previous versions, you really should upgrade.

If you decided to write your hello.World class in Kotlin, another issue might be that you have to reference it as mainClassName = "hello.WorldKt".

    ...
}
// class World {} // this line is not necessary

I tried the proposed solution above:

df[df["A"].str.contains("Hello|Britain")]

and got an error:

ValueError: cannot mask with array containing NA / NaN values

you can transform NA values into False, like this:

df[df["A"].str.contains("Hello|Britain", na=False)]

You should use "merge a range of revision".

To merge changes from the trunk to a branch, inside the branch working copy choose "merge range of revisions" and enter the trunk URL and the start and end revisions to merge.

The same in the opposite way to merge a branch in the trunk.

About the --reintegrate flag, check the manual here: http://tortoisesvn.net/docs/release/TortoiseSVN_en/tsvn-dug-merge.html#tsvn-dug-merge-reintegrate

The dat file has some lines of extra information before the actual data. Skip them with the skip argument:

read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat",

An easy way to check this if you are unfamiliar with the dataset is to first use readLines to check a few lines, as below:

readLines("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat", 
          n=10)
# [1] "Ozone data from CZ03 2009"   "Local time: GMT + 0"        
# [3] ""                            "Date        Hour      Value"
# [5] "01.01.2009 00:00       34.3" "01.01.2009 01:00       31.9"
# [7] "01.01.2009 02:00       29.9" "01.01.2009 03:00       28.5"
# [9] "01.01.2009 04:00       32.9" "01.01.2009 05:00       20.5"

Here, we can see that the actual data starts at [4], so we know to skip the first three lines.

Update

If you really only wanted the Value column, you could do that by:

as.vector(
    read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat",
               header=TRUE, skip=3)$Value)

Again, readLines is useful for helping us figure out the actual name of the columns we will be importing.

But I don't see much advantage to doing that over reading the whole dataset in and extracting later.

netem leverages functionality already built into Linux and userspace utilities to simulate networks. This is actually what Mark's answer refers to, by a different name.

The examples on their homepage already show how you can achieve what you've asked for:

Examples

Emulating wide area network delays

This is the simplest example, it just adds a fixed amount of delay to all packets going out of the local Ethernet.

# tc qdisc add dev eth0 root netem delay 100ms

Now a simple ping test to host on the local network should show an increase of 100 milliseconds. The delay is limited by the clock resolution of the kernel (Hz). On most 2.4 systems, the system clock runs at 100 Hz which allows delays in increments of 10 ms. On 2.6, the value is a configuration parameter from 1000 to 100 Hz.

Later examples just change parameters without reloading the qdisc

Real wide area networks show variability so it is possible to add random variation.

# tc qdisc change dev eth0 root netem delay 100ms 10ms

This causes the added delay to be 100 ± 10 ms. Network delay variation isn't purely random, so to emulate that there is a correlation value as well.

# tc qdisc change dev eth0 root netem delay 100ms 10ms 25%

This causes the added delay to be 100 ± 10 ms with the next random element depending 25% on the last one. This isn't true statistical correlation, but an approximation.

Delay distribution

Typically, the delay in a network is not uniform. It is more common to use a something like a normal distribution to describe the variation in delay. The netem discipline can take a table to specify a non-uniform distribution.

# tc qdisc change dev eth0 root netem delay 100ms 20ms distribution normal

The actual tables (normal, pareto, paretonormal) are generated as part of the iproute2 compilation and placed in /usr/lib/tc; so it is possible with some effort to make your own distribution based on experimental data.

Packet loss

Random packet loss is specified in the 'tc' command in percent. The smallest possible non-zero value is:

2^-32 = 0.0000000232%

# tc qdisc change dev eth0 root netem loss 0.1%

This causes 1/10th of a percent (i.e. 1 out of 1000) packets to be randomly dropped.

An optional correlation may also be added. This causes the random number generator to be less random and can be used to emulate packet burst losses.

# tc qdisc change dev eth0 root netem loss 0.3% 25%

This will cause 0.3% of packets to be lost, and each successive probability depends by a quarter on the last one.

Prob_n = 0.25 × Prob_n-1 + 0.75 × Random

Note that you should use tc qdisc add if you have no rules for that interface or tc qdisc change if you already have rules for that interface. Attempting to use tc qdisc change on an interface with no rules will give the error RTNETLINK answers: No such file or directory.

The nohup command is a signal masking utility and catches the hangup signal. Where as ampersand doesn’t catch the hang up signals. The shell will terminate the sub command with the hang up signal when running a command using & and exiting the shell. This can be prevented by using nohup, as it catches the signal. Nohup command accept hang up signal which can be sent to a process by the kernel and block them. Nohup command is helpful in when a user wants to start long running application log out or close the window in which the process was initiated. Either of these actions normally prompts the kernel to hang up on the application, but a nohup wrapper will allow the process to continue. Using the ampersand will run the command in a child process and this child of the current bash session. When you exit the session, all of the child processes of that process will be killed. The ampersand relates to job control for the active shell. This is useful for running a process in a session in the background.

I had a further issue that foxed me for a while when theming existing code from a CMS. I wanted to use flexbox with justify-content:space-between but the left and right elements weren't flush.

In that system the items were floated and the container had a :before and/or an :after to clear floats at beginning or end. So setting those sneaky :before and :after elements to display:none did the trick.

The answer by Craig Ringer is correct. Here's a little more info for Postgres 9.1 and later…

Is Extension Available?

You can only install an extension if it has already been built for your Postgres installation (your cluster in Postgres lingo). For example, I found the uuid-ossp extension included as part of the installer for Mac OS X kindly provided by EnterpriseDB.com. Any of a few dozen extensions may be available.

To see if the uuid-ossp extension is available in your Postgres cluster, run this SQL to query the pg_available_extensions system catalog:

SELECT * FROM pg_available_extensions;

Install Extension

To install that UUID-related extension, use the CREATE EXTENSION command as seen in this this SQL:

CREATE EXTENSION IF NOT EXISTS "uuid-ossp";

Beware: I found the QUOTATION MARK characters around extension name to be required, despite documentation to the contrary.

The SQL standards committee or Postgres team chose an odd name for that command. To my mind, they should have chosen something like "INSTALL EXTENSION" or "USE EXTENSION".

Verify Installation

You can verify the extension was successfully installed in the desired database by running this SQL to query the pg_extension system catalog:

SELECT * FROM pg_extension;

UUID as default value

For more info, see the Question: Default value for UUID column in Postgres

The Old Way

The information above uses the new Extensions feature added to Postgres 9.1. In previous versions, we had to find and run a script in a .sql file. The Extensions feature was added to make installation easier, trading a bit more work for the creator of an extension for less work on the part of the user/consumer of the extension. See my blog post for more discussion.

Types of UUIDs

By the way, the code in the Question calls the function uuid_generate_v4(). This generates a type known as Version 4 where nearly all of the 128 bits are randomly generated. While this is fine for limited use on smaller set of rows, if you want to virtually eliminate any possibility of collision, use another "version" of UUID.

For example, the original Version 1 combines the MAC address of the host computer with the current date-time and an arbitrary number, the chance of collisions is practically nil.

For more discussion, see my Answer on related Question.

I guess you've meant:

[{'name':'Homer', 'age':39}, {'name':'Bart', 'age':10}]

This would be sorted like this:

sorted(l,cmp=lambda x,y: cmp(x['name'],y['name']))

Some time This Code Not worked proper

Same-origin policy

https://en.wikipedia.org/wiki/Same-origin_policy

https://en.wikipedia.org/wiki/Cross-origin_resource_sharing

problem of Same-origin policy. Essentially, you cannot download this file from www.youtube.com because they are different domains. A workaround of this problem is [CORS][1]. 

Ref : https://superuser.com/questions/773719/how-do-all-of-these-save-video-from-youtube-services-work/773998#773998

url_encoded_fmt_stream_map // traditional: contains video and audio stream
adaptive_fmts              // DASH: contains video or audio stream

Each of these is a comma separated array of what I would call "stream objects". Each "stream object" will contain values like this

url  // direct HTTP link to a video
itag // code specifying the quality
s    // signature, security measure to counter downloading

Each URL will be encoded so you will need to decode them. Now the tricky part.

YouTube has at least 3 security levels for their videos

unsecured // as expected, you can download these with just the unencoded URL
s         // see below
RTMPE     // uses "rtmpe://" protocol, no known method for these

The RTMPE videos are typically used on official full length movies, and are protected with SWF Verification Type 2. This has been around since 2011 and has yet to be reverse engineered.

The type "s" videos are the most difficult that can actually be downloaded. You will typcially see these on VEVO videos and the like. They start with a signature such as

AA5D05FA7771AD4868BA4C977C3DEAAC620DE020E.0F421820F42978A1F8EAFCDAC4EF507DB5 Then the signature is scrambled with a function like this

function mo(a) {
  a = a.split("");
  a = lo.rw(a, 1);
  a = lo.rw(a, 32);
  a = lo.IC(a, 1);
  a = lo.wS(a, 77);
  a = lo.IC(a, 3);
  a = lo.wS(a, 77);
  a = lo.IC(a, 3);
  a = lo.wS(a, 44);
  return a.join("")
}

This function is dynamic, it typically changes every day. To make it more difficult the function is hosted at a URL such as

http://s.ytimg.com/yts/jsbin/html5player-en_US-vflycBCEX.js

this introduces the problem of Same-origin policy. Essentially, you cannot download this file from www.youtube.com because they are different domains. A workaround of this problem is CORS. With CORS, s.ytimg.com could add this header

Access-Control-Allow-Origin: http://www.youtube.com

and it would allow the JavaScript to download from www.youtube.com. Of course they do not do this. A workaround for this workaround is to use a CORS proxy. This is a proxy that responds with the following header to all requests

Access-Control-Allow-Origin: *

So, now that you have proxied your JS file, and used the function to scramble the signature, you can use that in the querystring to download a video.

If you dig into NSInteger's implementation:

#if __LP64__
typedef long NSInteger;
#else
typedef int NSInteger;
#endif

Simply, the NSInteger typedef does a step for you: if the architecture is 32-bit, it uses int, if it is 64-bit, it uses long. Using NSInteger, you don't need to worry about the architecture that the program is running on.

The accepted answer failed to load the "Reviews" tab. I found below method to load the "Review" tab without "Details" tab.

[[UIApplication sharedApplication] openURL:[NSURL URLWithString: @"itms-apps://itunes.apple.com/WebObjects/MZStore.woa/wa/viewContentsUserReviews?type=Purple+Software&id={APP_ID}&pageNumber=0&sortOrdering=2&mt=8"]];

Replace {APP_ID} with your app apps store app id.

PEP-8 recommends you indent lines to the opening parentheses if you put anything on the first line, so it should either be indenting to the opening bracket:

urlpatterns = patterns('',
                       url(r'^$', listing, name='investment-listing'))

or not putting any arguments on the starting line, then indenting to a uniform level:

urlpatterns = patterns(
    '',
    url(r'^$', listing, name='investment-listing'),
)

urlpatterns = patterns(
    '', url(r'^$', listing, name='investment-listing'))

I suggest taking a read through PEP-8 - you can skim through a lot of it, and it's pretty easy to understand, unlike some of the more technical PEPs.

You asked about performance. See this perf test comparing 'concat', '+' and 'join' - in short the + operator wins by far.

Imagine that this is your Json response

{"Visit":{"VisitId":8,"Description":"visit8"}}

This is how you parse the response and access the values

    Ext.Ajax.request({
    headers: {
        'Content-Type': 'application/json'
    },
    url: 'api/fullvisit/getfullvisit/' + visitId,
    method: 'GET',
    dataType: 'json',
    success: function (response, request) {
        obj = JSON.parse(response.responseText);
        alert(obj.Visit.VisitId);
    }
});

This will alert the VisitId field

maybe this is what u want?

const input = '0093';
const match = input.match(/^(0+)(\d+)$/);
const result = match && match[2] || input;

Shog9 is right that this doesn't make all that much sense to ask, since an object could be referred to by multiple variables. If you don't really care about that, and all you want is to find the name of one of the global variables that refers to that object, you could do the following hack:

function myClass() { 
  this.myName = function () { 
    // search through the global object for a name that resolves to this object
    for (var name in this.global) 
      if (this.global[name] == this) 
        return name 
  } 
}
// store the global object, which can be referred to as this at the top level, in a
// property on our prototype, so we can refer to it in our object's methods
myClass.prototype.global = this
// create a global variable referring to an object
var myVar = new myClass()
myVar.myName() // returns "myVar"

Note that this is an ugly hack, and should not be used in production code. If there is more than one variable referring to an object, you can't tell which one you'll get. It will only search the global variables, so it won't work if a variable is local to a function. In general, if you need to name something, you should pass the name in to the constructor when you create it.

edit: To respond to your clarification, if you need to be able to refer to something from an event handler, you shouldn't be referring to it by name, but instead add a function that refers to the object directly. Here's a quick example that I whipped up that shows something similar, I think, to what you're trying to do:

function myConstructor () {
  this.count = 0
  this.clickme = function () {
    this.count += 1
    alert(this.count)
  }

  var newDiv = document.createElement("div")
  var contents = document.createTextNode("Click me!")

  // This is the crucial part. We don't construct an onclick handler by creating a
  // string, but instead we pass in a function that does what we want. In order to
  // refer to the object, we can't use this directly (since that will refer to the 
  // div when running event handler), but we create an anonymous function with an 
  // argument and pass this in as that argument.

Other solutions are good enough to answer your query. However, if you are looking for just one command to do that for you -

Create a file name "run", in directory where your Java files are. And save this in your file -

javac "$1.java"
if [ $? -eq 0 ]; then
  echo "--------Run output-------"
  java "$1"
fi

give this file run permission by running -

chmod 777 

Now you can run any of your files by merely running -

./run <yourfilename> (don't add .java in filename)

The above answers are fine but I would add to be sure the div is defined in the designer.cs file. This doesn't always happen when adding a div to the .aspx file. Not sure why but there are threads concerning this issue in this forum. Eg:

protected global::System.Web.UI.HtmlControls.HtmlGenericControl theDiv;

perhaps, you can first determine if the DOM does really exists,

function walkmydog() {
    //when the user starts entering
    var dom = document.getElementById('WallSearch');
    if(dom == null){
        alert('sorry, WallSearch DOM cannot be found');
        return false;    
    }

    if(dom.value.length == 0){
        alert("nothing");
    }
}

if (document.addEventListener){
    document.addEventListener("DOMContentLoaded", walkmydog, false);
}

The innerHTML fetches content depending on the id/name and replaces them.

<!DOCTYPE html>_x000D_
<html>_x000D_
<head>_x000D_
 <title>Learn JavaScript</title>_x000D_
</head>_x000D_
<body>_x000D_
<button type = "button"_x000D_
onclick="document.getElementById('demo').innerHTML = Date()"> <!--fetches the content with id demo and changes the innerHTML content to Date()-->_x000D_
Click for date_x000D_
</button>_x000D_
<h3 id = 'demo'>Before Button is clicked this content will be Displayed the inner content of h3 tag with id demo and once you click the button this will be replaced by the Date() ,which prints the current date and time </h3> _x000D_
_x000D_
</body>_x000D_
</html>

When you click the button,the content in h3 will be replaced by innerHTML assignent i.e Date() .

For me, this error occurred because of a null parameter being passed. Checking the variable values fixed my issue without having to change the code. I used BackgroundWorker.

I had the same problem in the iphone or desktop, didnt manage to close the dialog when pressing the close button.

i found out that The <button> tag defines a clickable button and is needed to specify the type attribute for a element as follow:

<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>

I just used the following which was quite simple. First open a console then cd to where you've downloaded your file like some-package.whl and use

pip install some-package.whl

Note: if pip.exe is not recognized, you may find it in the "Scripts" directory from where python has been installed. If pip is not installed, this page can help: How do I install pip on Windows?

Note: for clarification
If you copy the *.whl file to your local drive (ex. C:\some-dir\some-file.whl) use the following command line parameters --

pip install C:/some-dir/some-file.whl

var_dump() :-

1. This function displays structured information about one or more expressions that includes its type and value. Arrays and objects are explored recursively with values indented to show structure.
2. This function display number of element in a variable.
3. This function display length of variable.
4. Can't return the value only print the value.
5. it is use for debugging purpose.

Example :-

<?php
$a = array(1, 2, array("a", "b", "c"));
var_dump($a);
?>

output :-

   array(3) {
  [0]=>
  int(1)
  [1]=>
  int(2)
  [2]=>
  array(3) {
    [0]=>
    string(1) "a"
    [1]=>
    string(1) "b"
    [2]=>
    string(1) "c"
  }
}

print_r() :-

1. Prints human-readable information about a variable.
2. Not display number of element in a variable as var_dump().
3. Not display length of variable in a variable as var_dump().
4. Return the value if we set second parameter to true in printf_r().

Example :-

<pre>
<?php
$a = array ('a' => 'apple', 'b' => 'banana', 'c' => array ('x', 'y', 'z'));
print_r ($a);
?>
</pre>

Output:-

<pre>
Array
(
    [a] => apple
    [b] => banana
    [c] => Array
        (
            [0] => x
            [1] => y
            [2] => z
        )
)
</pre>

Visual Studio for Windows Apps is meant to be used to build Windows Store Apps using HTML & Javascript or WinRT and XAML. These can also run on the Windows tablet that run Windows RT.

Visual Studio for Windows Desktop is meant to build applications using Windows Forms or Windows Presentation Foundation, these can run on Windows 8.1 on a normal desktop or on a tablet device like the Surface Pro in desktop mode (like a classic windows application).

I had a doubt that whether the encrypted text will be same for single text when encryption done by multiple times on a same text??

This depends strongly on the crypto algorithm you use:

• One goal of some/most (mature) algorithms is that the encrypted text is different when encryption done twice. One reason to do this is, that an attacker how known the plain and the encrypted text is not able to calculate the key.
• Other algorithm (mainly one way crypto hashes) like MD5 or SHA based on the fact, that the hashed text is the same for each encryption/hash.

In this particular example, it makes no difference. However, the {} in ${} are useful if you want to expand the variable foo in the string

"${foo}bar"

since "$foobar" would instead expand the variable identified by foobar.

Curly braces are also unconditionally required when:

• expanding array elements, as in ${array[42]}
• using parameter expansion operations, as in ${filename%.*} (remove extension)
• expanding positional parameters beyond 9: "$8 $9 ${10} ${11}"

Doing this everywhere, instead of just in potentially ambiguous cases, can be considered good programming practice. This is both for consistency and to avoid surprises like $foo_$bar.jpg, where it's not visually obvious that the underscore becomes part of the variable name.

For me, it worked,

final String basicAuth = "Basic " + Base64.encodeToString("user:password".getBytes(), Base64.NO_WRAP);

Apache HttpCLient:

request.setHeader("Authorization", basicAuth);

HttpUrlConnection:

connection.setRequestProperty ("Authorization", basicAuth);

If you want to fix vbs associations type

regsvr32 vbscript.dll
regsvr32 jscript.dll
regsvr32 wshext.dll
regsvr32 wshom.ocx
regsvr32 wshcon.dll
regsvr32 scrrun.dll

Also if you can't use vbs due to management then convert your script to a vb.net program which is designed to be easy, is easy, and takes 5 minutes.

Big difference is functions and subs are both called using brackets rather than just functions.

So the compilers are installed on all computers with .NET installed.

See this article here on how to make a .NET exe. Note the sample is for a scripting host. You can't use this, you have to put your vbs code in as .NET code.

How can I convert a VBScript to an executable (EXE) file?

Try using absolute positioning, rather than relative positioning

this should get you close - you can adjust by tweaking margins or top/left positions

    left: 50%;
}

Since the problem is the non-trivial destructor so if the destructor is removed from the std::string, it's possible to define a constexpr instance of that type. Like this

struct constexpr_str {
    char const* str;
    std::size_t size;

    // can only construct from a char[] literal
    template <std::size_t N>
    constexpr constexpr_str(char const (&s)[N])
        : str(s)
        , size(N - 1) // not count the trailing nul
    {}
};

int main()
{
    constexpr constexpr_str s("constString");

    // its .size is a constexpr
    std::array<int, s.size> a;
    return 0;
}

Well, technically any such object will wind up being built over a C-style thread library because C++ only just specified a stock std::thread model in c++0x, which was just nailed down and hasn't yet been implemented. The problem is somewhat systemic, technically the existing c++ memory model isn't strict enough to allow for well defined semantics for all of the 'happens before' cases. Hans Boehm wrote an paper on the topic a while back and was instrumental in hammering out the c++0x standard on the topic.

http://www.hpl.hp.com/techreports/2004/HPL-2004-209.html

That said there are several cross-platform thread C++ libraries that work just fine in practice. Intel thread building blocks contains a tbb::thread object that closely approximates the c++0x standard and Boost has a boost::thread library that does the same.

http://www.threadingbuildingblocks.org/

http://www.boost.org/doc/libs/1_37_0/doc/html/thread.html

Using boost::thread you'd get something like:

#include <boost/thread.hpp>

void task1() { 
    // do stuff
}

void task2() { 
    // do stuff
}

int main (int argc, char ** argv) {
    using namespace boost; 
    thread thread_1 = thread(task1);
    thread thread_2 = thread(task2);

    // do other stuff
    thread_2.join();
    thread_1.join();
    return 0;
}

Just in case anyone is in my boat where none of these answers worked exactly, here's what I did.

Perhaps our in house Bitbucket server is set up a little differently than most, but here's the URL that I'd normally go to just to view the files in the master branch:

https://<BITBUCKET_URL>/projects/<PROJECT_GROUP>/repos/<REPO_NAME>/browse

If I select a different branch than master from the drop down menu, I get this:

https://<BITBUCKET_URL>/projects/<PROJECT_GROUP>/repos/<REPO_NAME>/browse?at=refs%2Fheads%2F<BRANCH_NAME>

So I tried doing this and it worked:

https://<BITBUCKET_URL>/projects/<PROJECT_GROUP>/repos/<REPO_NAME>/browse?at=<COMMIT_ID>

Now I can browse the whole repo as it was at the time of that commit.

Your vector<string> userString has size 0, so the loop is never entered. You could start with a vector of a given size:

vector<string> userString(10);      
string word;        
string sentence;           
for (decltype(userString.size()) i = 0; i < userString.size(); ++i)
{
    cin >> word;
    userString[i] = word;
    sentence += userString[i] + " ";
}

although it is not clear why you need the vector at all:

string word;        
string sentence;           
for (int i = 0; i < 10; ++i)
{
    cin >> word;
    sentence += word + " ";
}

If you don't want to have a fixed limit on the number of input words, you can use std::getline in a while loop, checking against a certain input, e.g. "q":

while (std::getline(std::cin, word) && word != "q")
{
    sentence += word + " ";
}

This will add words to sentence until you type "q".

Simply put this is constraining the generic parameter to a class (or more specifically a reference type which could be a class, interface, delegate, or array type).

See this MSDN article for further details.

By adding filter action my problem resolved

 // Register for broadcasts when a device is discovered
    IntentFilter intentFilter = new IntentFilter();

    intentFilter.addAction(BluetoothAdapter.ACTION_DISCOVERY_STARTED);
    intentFilter.addAction(BluetoothAdapter.ACTION_DISCOVERY_FINISHED);
    registerReceiver(mReceiver, intentFilter);

You are missing a closing h2 tag. It should be:

Pros

• Fixed-width layouts are much easier to use and easier to customize in terms of design.
• Widths are the same for every browser, so there is less hassle with images, forms, video and other content that are fixed-width.
• There is no need for min-width or max-width, which isn’t supported by every browser anyway.
• Even if a website is designed to be compatible with the smallest screen resolution, 800×600, the content will still be wide enough at a larger resolution to be easily legible.

Cons

• A fixed-width layout may create excessive white space for users with larger screen resolutions, thus upsetting “divine proportion,” the “Rule of Thirds,” overall balance and other design principles.
• Smaller screen resolutions may require a horizontal scroll bar, depending the fixed layout’s width.
• Seamless textures, patterns and image continuation are needed to accommodate those with larger resolutions.
• Fixed-width layouts generally have a lower overall score when it comes to usability.

First of all you need to remove the data-toggle attribute. We will use some JQuery, so make sure you include it.

  <ul class='nav nav-tabs'>
    <li class='active'><a href='#home'>Home</a></li>
    <li><a href='#menu1'>Menu 1</a></li>
    <li><a href='#menu2'>Menu 2</a></li>
    <li><a href='#menu3'>Menu 3</a></li>
  </ul>

  <div class='tab-content'>
    <div id='home' class='tab-pane fade in active'>
      <h3>HOME</h3>
    <div id='menu1' class='tab-pane fade'>
      <h3>Menu 1</h3>
    </div>
    <div id='menu2' class='tab-pane fade'>
      <h3>Menu 2</h3>
    </div>
    <div id='menu3' class='tab-pane fade'>
      <h3>Menu 3</h3>
    </div>
  </div>
</div>

<script>
$(document).ready(function(){
// Handling data-toggle manually
    $('.nav-tabs a').click(function(){
        $(this).tab('show');
    });
// The on tab shown event
    $('.nav-tabs a').on('shown.bs.tab', function (e) {
        alert('Hello from the other siiiiiide!');
        var current_tab = e.target;
        var previous_tab = e.relatedTarget;
    });
});

Even on a plain x86 32 bit platform, you can get a variety of pointer sizes, try this out for an example:

struct A {};

struct B : virtual public A {};

struct C {};

struct D : public A, public C {};

int main()
{
    cout << "A:" << sizeof(void (A::*)()) << endl;
    cout << "B:" << sizeof(void (B::*)()) << endl;
    cout << "D:" << sizeof(void (D::*)()) << endl;
}

Under Visual C++ 2008, I get 4, 12 and 8 for the sizes of the pointers-to-member-function.

UPDATE: 9/24/16 Angular 2.0 Stable

This question gets a lot of traffic still, so, I wanted to update it. With the insanity of changes from Alpha, Beta, and 7 RC candidates, I stopped updating my SO answers until they went stable.

This is the perfect case for using Subjects and ReplaySubjects

I personally prefer to use ReplaySubject(1) as it allows the last stored value to be passed when new subscribers attach even when late:

let project = new ReplaySubject(1);

//subscribe
project.subscribe(result => console.log('Subscription Streaming:', result));

http.get('path/to/whatever/projects/1234').subscribe(result => {
    //push onto subject
    project.next(result));

    //add delayed subscription AFTER loaded
    setTimeout(()=> project.subscribe(result => console.log('Delayed Stream:', result)), 3000);
});

//Output
//Subscription Streaming: 1234
//*After load and delay*
//Delayed Stream: 1234

So even if I attach late or need to load later I can always get the latest call and not worry about missing the callback.

This also lets you use the same stream to push down onto:

project.next(5678);
//output
//Subscription Streaming: 5678

But what if you are 100% sure, that you only need to do the call once? Leaving open subjects and observables isn't good but there's always that "What If?"

That's where AsyncSubject comes in.

let project = new AsyncSubject();

//subscribe
project.subscribe(result => console.log('Subscription Streaming:', result),
                  err => console.log(err),
                  () => console.log('Completed'));

http.get('path/to/whatever/projects/1234').subscribe(result => {
    //push onto subject and complete
    project.next(result));
    project.complete();

    //add a subscription even though completed
    setTimeout(() => project.subscribe(project => console.log('Delayed Sub:', project)), 2000);
});

//Output
//Subscription Streaming: 1234
//Completed
//*After delay and completed*
//Delayed Sub: 1234

Awesome! Even though we closed the subject it still replied with the last thing it loaded.

Another thing is how we subscribed to that http call and handled the response. Map is great to process the response.

public call = http.get(whatever).map(res => res.json())

But what if we needed to nest those calls? Yes you could use subjects with a special function:

getThing() {
    resultSubject = new ReplaySubject(1);

    http.get('path').subscribe(result1 => {
        http.get('other/path/' + result1).get.subscribe(response2 => {
            http.get('another/' + response2).subscribe(res3 => resultSubject.next(res3))
        })
    })
    return resultSubject;
}
var myThing = getThing();

But that's a lot and means you need a function to do it. Enter FlatMap:

var myThing = http.get('path').flatMap(result1 => 
                    http.get('other/' + result1).flatMap(response2 => 
                        http.get('another/' + response2)));

Sweet, the var is an observable that gets the data from the final http call.

OK thats great but I want an angular2 service!

I got you:

import { Injectable } from '@angular/core';
import { Http, Response } from '@angular/http';
import { ReplaySubject } from 'rxjs';

@Injectable()
export class ProjectService {

  public activeProject:ReplaySubject<any> = new ReplaySubject(1);

  constructor(private http: Http) {}

  //load the project
  public load(projectId) {
    console.log('Loading Project:' + projectId, Date.now());
    this.http.get('/projects/' + projectId).subscribe(res => this.activeProject.next(res));
    return this.activeProject;
  }

 }

 //component

@Component({
    selector: 'nav',
    template: `<div>{{project?.name}}<a (click)="load('1234')">Load 1234</a></div>`
})
 export class navComponent implements OnInit {
    public project:any;

    constructor(private projectService:ProjectService) {}

    ngOnInit() {
        this.projectService.activeProject.subscribe(active => this.project = active);
    }

    public load(projectId:string) {
        this.projectService.load(projectId);
    }

 }

I'm a big fan of observers and observables so I hope this update helps!

Original Answer

I think this is a use case of using a Observable Subject or in Angular2 the EventEmitter.

In your service you create a EventEmitter that allows you to push values onto it. In Alpha 45 you have to convert it with toRx(), but I know they were working to get rid of that, so in Alpha 46 you may be able to simply return the EvenEmitter.

class EventService {
  _emitter: EventEmitter = new EventEmitter();
  rxEmitter: any;
  constructor() {
    this.rxEmitter = this._emitter.toRx();
  }
  doSomething(data){
    this.rxEmitter.next(data);
  }
}

This way has the single EventEmitter that your different service functions can now push onto.

If you wanted to return an observable directly from a call you could do something like this:

myHttpCall(path) {
    return Observable.create(observer => {
        http.get(path).map(res => res.json()).subscribe((result) => {
            //do something with result. 
            var newResultArray = mySpecialArrayFunction(result);
            observer.next(newResultArray);
            //call complete if you want to close this stream (like a promise)
            observer.complete();
        });
    });
}

That would allow you do this in the component: peopleService.myHttpCall('path').subscribe(people => this.people = people);

And mess with the results from the call in your service.

I like creating the EventEmitter stream on its own in case I need to get access to it from other components, but I could see both ways working...

Here's a plunker that shows a basic service with an event emitter: Plunkr

Works well for me this (when dir exist):

some_dir="/some/dir with whitespace & other characters/"
if find "`echo "$some_dir"`" -maxdepth 0 -empty | read v; then echo "Empty dir"; fi

With full check:

if [ -d "$some_dir" ]; then
  if find "`echo "$some_dir"`" -maxdepth 0 -empty | read v; then echo "Empty dir"; else "Dir is NOT empty" fi
fi

Absolutely it must be work!

When you generate a JAXB model from an XML Schema, global elements that correspond to named complex types will have that metadata captured as an @XmlElementDecl annotation on a create method in the ObjectFactory class. Since you are creating the JAXBContext on just the DocumentType class this metadata isn't being processed. If you generated your JAXB model from an XML Schema then you should create the JAXBContext on the generated package name or ObjectFactory class to ensure all the necessary metadata is processed.

Example solution:

JAXBContext jaxbContext = JAXBContext.newInstance(my.generatedschema.dir.ObjectFactory.class);
DocumentType documentType = ((JAXBElement<DocumentType>) jaxbContext.createUnmarshaller().unmarshal(inputStream)).getValue();

As Quoted by mattjames

The use of a Statement in JDBC should be 100% localized to being used for DDL (ALTER, CREATE, GRANT, etc) as these are the only statement types that cannot accept BIND VARIABLES. PreparedStatements or CallableStatements should be used for EVERY OTHER type of statement (DML, Queries). As these are the statement types that accept bind variables.

This is a fact, a rule, a law -- use prepared statements EVERYWHERE. Use STATEMENTS almost no where.

abs function is definitely not what you need as it is not calculating the distance. Try abs (-25+15) to see that it's not working. A distance between the numbers is 40 but the output will be 10. Because it's doing the math and then removing "minus" in front. I am using this custom function:

def distance(a, b):
    if (a < 0) and (b < 0) or (a > 0) and (b > 0):
        return abs( abs(a) - abs(b) )
    if (a < 0) and (b > 0) or (a > 0) and (b < 0):
        return abs( abs(a) + abs(b) )

print distance(-25, -15)
print distance(25, -15)
print distance(-25, 15)
print distance(25, 15)

I know this post is quite old, but still, if anyone using IntelliJ any want to see dependency tree directly in IDE then they can install Maven Helper Plugin plugin.

Once installed open pom.xml and you would able to see Dependency Analyze tab like below. It also provides option to see dependency that is conflicted only and also as a tree structure.

Just loop...

foreach(var table in DataSet1.Tables) {
    foreach(var col in table.Columns) {
       ...
    }
    foreach(var row in table.Rows) {
        object[] values = row.ItemArray;
        ...
    }
}

The best practice for this, in my opinion is:

TimeUnit.DAYS.toMillis(1);     // 1 day to milliseconds.
TimeUnit.MINUTES.toMillis(23); // 23 minutes to milliseconds.
TimeUnit.HOURS.toMillis(4);    // 4 hours to milliseconds.
TimeUnit.SECONDS.toMillis(96); // 96 seconds to milliseconds.

Nothing has worked. The solution for the issue is.

<style>
table td {
    padding: 0;
}
</style>

What i do ;

<body>
<script>
function getWidth(){
return Math.max(document.body.scrollWidth,
document.documentElement.scrollWidth,
document.body.offsetWidth,
document.documentElement.offsetWidth,
document.documentElement.clientWidth);
}
var aWidth=getWidth();
</script>
...

and call aWidth variable anywhere afterwards.

You need to put the getWidth() up in your document body to make sure that the scrollbar width is counted, else scrollbar width of the browser subtracted from getWidth().

I know I'm late to the party but I find the zerofill is helpful for boolean representations of TINYINT(1). Null doesn't always mean False, sometimes you don't want it to. By zerofilling a tinyint, you're effectively converting those values to INT and removing any confusion ur application may have upon interaction. Your application can then treat those values in a manner similar to the primitive datatype True = Not(0)

Are they the home directories of users in /etc/passwd? Services like postgres, sendmail, apache, etc., create system users that have home directories just like normal users.

Let's assume the next point : the hackers steal our database including the users and password (encrypted). And the hackers created a fake account with a password that they know.

MD5 is weak because its short and popular and practically every hash generation without password is weak of a dictionary attack. But..

So, let's say that we are still using MD5 with a SALT. The hackers don't know the SALT but they know the password of a specific user. So they can test : ?????12345 where 12345 is the know password and ????? is the salt. The hackers sooner or later can guess the SALT.

However, if we used a MD5+SALT and we applied MD5, then there is not way to recover the information. However, i repeat, MD5 is still short.

For example, let's say that my password is : 12345. The SALT is BILLCLINTON

md5 : 827ccb0eea8a706c4c34a16891f84e7b

md5 with the hash : 56adb0f19ac0fb50194c312d49b15378

mD5 with the hash over md5 : 28a03c0bc950decdd9ee362907d1798a I tried to use those online service and i found none that was able to crack it. And its only MD5! (may be as today it will be crackeable because i generated the md5 online)

If you want to overkill then SHA256 is more than enough if its applied with a salt and twice.

tldr MD5(HASH+MD5(password)) = ok but short, SHA256 is more than enough.

1. pageX/Y gives the coordinates relative to the <html> element in CSS pixels.
2. clientX/Y gives the coordinates relative to the viewport in CSS pixels.
3. screenX/Y gives the coordinates relative to the screen in device pixels.

Regarding your last question if calculations are similar on desktop and mobile browsers... For a better understanding - on mobile browsers - we need to differentiate two new concept: the layout viewport and visual viewport. The visual viewport is the part of the page that's currently shown onscreen. The layout viewport is synonym for a full page rendered on a desktop browser (with all the elements that are not visible on the current viewport).

On mobile browsers the pageX and pageY are still relative to the page in CSS pixels so you can obtain the mouse coordinates relative to the document page. On the other hand clientX and clientY define the mouse coordinates in relation to the visual viewport.

There is another stackoverflow thread here regarding the differences between the visual viewport and layout viewport : Difference between visual viewport and layout viewport?

Another good resource: http://www.quirksmode.org/mobile/viewports2.html

I have never had any luck with any scrollable content placed inside a stackpanel (anything derived from ScrollableContainer. The stackpanel has an odd layout mechanism that confuses child controls when the measure operation is completed and I found the vertical size ends up infinite, therefore not constrained - so it goes beyond the boundaries of the container and ends up clipped. The scrollbar doesn't show because the control thinks it has all the space in the world when it doesn't.

You should always place scrollable content inside a container that can resolve to a known height during its layout operation at runtime so that the scrollbars size appropriately. The parent container up in the visual tree must be able to resolve to an actual height, and this happens in the grid if you set the height of the RowDefinition o to auto or fixed.

This also happens in Silverlight.

For the searching, use querystrings. This is perfectly RESTful:

/cars?color=blue&type=sedan&doors=4

An advantage to regular querystrings is that they are standard and widely understood and that they can be generated from form-get.

How about this?

this.http.get(targetUrl,{responseType:ResponseContentType.Blob})
        .catch((err)=>{return [do yourself]})
        .subscribe((res:Response)=>{
          var a = document.createElement("a");
          a.href = URL.createObjectURL(res.blob());
          a.download = fileName;
          // start download
          a.click();
        })

I could do with it.
no need additional package.

The pthread_exit() API

as has been already remarked, is used for the calling thread termination. After a call to that function a complicating clean up mechanism is started. When it completes the thread is terminated. The pthread_exit() API is also called implicitly when a call to the return() routine occurs in a thread created by pthread_create(). Actually, a call to return() and a call to pthread_exit() have the same impact, being called from a thread created by pthread_create().

It is very important to distinguish the initial thread, implicitly created when the main() function starts, and threads created by pthread_create(). A call to the return() routine from the main() function implicitly invokes the exit() system call and the entire process terminates. No thread clean up mechanism is started. A call to the pthread_exit() from the main() function causes the clean up mechanism to start and when it finishes its work the initial thread terminates.

What happens to the entire process (and to other threads) when pthread_exit() is called from the main() function depends on the PTHREAD implementation. For example, on IBM OS/400 implementation the entire process is terminated, including other threads, when pthread_exit() is called from the main() function. Other systems may behave differently. On most modern Linux machines a call to pthread_exit() from the initial thread does not terminate the entire process until all threads termination. Be careful using pthread_exit() from main(), if you want to write a portable application.

The pthread_join() API

is a convenient way to wait for a thread termination. You may write your own function that waits for a thread termination, perhaps more suitable to your application, instead of using pthread_join(). For example, it can be a function based on waiting on conditional variables.

I would recommend for reading a book of David R. Butenhof “Programming with POSIX Threads”. It explains the discussed topics (and more complicated things) very well (although some implementation details, such as pthread_exit usage in the main function, not always reflected in the book).

Daniel Hilgarth's answer above leads to a System.NotSupported exception With Entity-Framework. With Entity-Framework, it has to be:

table1.GroupBy(x => x.Text).Select(x => x.FirstOrDefault());

The best way

The best way is to insert an appropriate input tag:

<input type="submit" value="submit" />

The best JS way

<form id="form-id">
  <button id="your-id">submit</button>
</form>

var form = document.getElementById("form-id");

document.getElementById("your-id").addEventListener("click", function () {
  form.submit();
});

Enclose the latter JavaScript code by an DOMContentLoaded event (choose only load for backward compatiblity) if you haven't already done so:

window.addEventListener("DOMContentLoaded", function () {
  var form = document.... // copy the last code block!
});

The easy, not recommandable way (the former answer)

Add an onclick attribute to the link and an id to the form:

<form id="form-id">

  <a href="#" onclick="document.getElementById('form-id').submit();"> submit </a>

</form>

All ways

Whatever way you choose, you have call formObject.submit() eventually (where formObject is the DOM object of the <form> tag).

You also have to bind such an event handler, which calls formObject.submit(), so it gets called when the user clicked a specific link or button. There are two ways:

• Recommended: Bind an event listener to the DOM object.

  // 1. Acquire a reference to our <form>.
  //    This can also be done by setting <form name="blub">:
  //       var form = document.forms.blub;
  
  var form = document.getElementById("form-id");
  
  
  // 2. Get a reference to our preferred element (link/button, see below) and
  //    add an event listener for the "click" event.
  document.getElementById("your-id").addEventListener("click", function () {
    form.submit();
  });
  

• Not recommended: Insert inline JavaScript. There are several reasons why this technique is not recommendable. One major argument is that you mix markup (HTML) with scripts (JS). The code becomes unorganized and rather unmaintainable.

  <a href="#" onclick="document.getElementById('form-id').submit();">submit</a>
  
  <button onclick="document.getElementById('form-id').submit();">submit</button>
  

Now, we come to the point at which you have to decide for the UI element which triggers the submit() call.

1. A button

   <button>submit</button>
   

2. A link

   <a href="#">submit</a>
   

Apply the aforementioned techniques in order to add an event listener.

PHP is a server side language - it's executed on the server only, and the resultant program output is sent to the client. As such, there's no "client screen" information available.

That said, you can have the client tell you what their screen resolution is via JavaScript. Write a small scriptlet to send you screen.width and screen.height - possibly via AJAX, or more likely with an initial "jump page" that finds it, then redirects to http://example.net/index.php?size=AxB

Though speaking as a user, I'd much prefer you to design a site to fluidly handle any screen resolution. I browse in different sized windows, mostly not maximized.

As others have said, you are adding the same key more than once. If this is a NOT a valid scenario, then check Jdinklage Morgoone's answer (which only saves the first value found for a key), or, consider this workaround (which only saves the last value found for a key):

// This will always overwrite the existing value if one is already stored for this key
rct3Features[items[0]] = items[1];

Otherwise, if it is valid to have multiple values for a single key, then you should consider storing your values in a List<string> for each string key.

For example:

var rct3Features = new Dictionary<string, List<string>>();
var rct4Features = new Dictionary<string, List<string>>();

foreach (string line in rct3Lines)
{
    string[] items = line.Split(new String[] { " " }, 2, StringSplitOptions.None);

    if (!rct3Features.ContainsKey(items[0]))
    {
        // No items for this key have been added, so create a new list
        // for the value with item[1] as the only item in the list
        rct3Features.Add(items[0], new List<string> { items[1] });
    }
    else
    {
        // This key already exists, so add item[1] to the existing list value
        rct3Features[items[0]].Add(items[1]);
    }
}

// To display your keys and values (testing)
foreach (KeyValuePair<string, List<string>> item in rct3Features)
{
    Console.WriteLine("The Key: {0} has values:", item.Key);
    foreach (string value in item.Value)
    {
        Console.WriteLine(" - {0}", value);
    }
}

In my case even after uninstalling all 2005 related components it didn't worked. I had to resort to a brute force way and remove following registry keys

32 Bit OS: HKLM\SOFTWARE\Microsoft\Microsoft SQL Server\90

64 Bit OS: HKLM\Software\Wow6432Node\Microsoft\Microsoft SQL Server\90

Because recursion is always the answer.

function getPosition(input, search, nth, curr, cnt) {
    curr = curr || 0;
    cnt = cnt || 0;
    var index = input.indexOf(search);
    if (curr === nth) {
        if (~index) {
            return cnt;
        }
        else {
            return -1;
        }
    }
    else {
        if (~index) {
            return getPosition(input.slice(index + search.length),
              search,
              nth,
              ++curr,
              cnt + index + search.length);
        }
        else {
            return -1;
        }
    }
}

REST webservice: (http://localhost:8080/your-app/rest/data/post)

package com.yourorg.rest;

import javax.ws.rs.Consumes;
import javax.ws.rs.POST; 
import javax.ws.rs.Path; 
import javax.ws.rs.Produces; 
import javax.ws.rs.core.MediaType; 
import javax.ws.rs.core.Response;

    @Path("/data")
public class JSONService {

    @POST
    @Path("/post")
    @Consumes(MediaType.APPLICATION_JSON)
    public Response createDataInJSON(String data) { 

        String result = "Data post: "+data;

        return Response.status(201).entity(result).build(); 
    }

Client send a post:

package com.yourorg.client;

import com.sun.jersey.api.client.Client;
import com.sun.jersey.api.client.ClientResponse;
import com.sun.jersey.api.client.WebResource;

public class JerseyClientPost {

  public static void main(String[] args) {

    try {

        Client client = Client.create();

        WebResource webResource = client.resource("http://localhost:8080/your-app/rest/data/post");

        String input = "{\"message\":\"Hello\"}";

        ClientResponse response = webResource.type("application/json")
           .post(ClientResponse.class, input);

        if (response.getStatus() != 201) {
            throw new RuntimeException("Failed : HTTP error code : "
                 + response.getStatus());
        }

        System.out.println("Output from Server .... \n");
        String output = response.getEntity(String.class);
        System.out.println(output);

      } catch (Exception e) {

        e.printStackTrace();

      }

    }
}

You are POSTing from the client:

await client.PostAsJsonAsync("api/products", product);

not PUTing.

Your Web API method accepts only PUT requests.

So:

await client.PutAsJsonAsync("api/products", product);

If the column is a timestamp you can do the following:

        if(fromDate!=null){
            criteria.add(Restrictions.sqlRestriction("TRUNC(COLUMN) >= TO_DATE('" + dataFrom + "','dd/mm/yyyy')"));
        }
        if(toDate!=null){               
            criteria.add(Restrictions.sqlRestriction("TRUNC(COLUMN) <= TO_DATE('" + dataTo + "','dd/mm/yyyy')"));
        }

        resultDB = criteria.list();

DT[order(-x)] works as expected. I have data.table version 1.9.4. Maybe this was fixed in a recent version.
Also, I suggest the setorder(DT, -x) syntax in keeping with the set* commands like setnames, setkey

import json

myDict = {'dict': [{'a': 'none', 'b': 'none', 'c': 'none'}]}
test = json.dumps(myDict)
print(test)

{"dict": [{"a": "none", "b": "none", "c": "none"}]}

myDict['dict'].append(({'a': 'aaaa', 'b': 'aaaa', 'c': 'aaaa'}))
test = json.dumps(myDict)
print(test)

{"dict": [{"a": "none", "b": "none", "c": "none"}, {"a": "aaaa", "b": "aaaa", "c": "aaaa"}]}

You can set protocol versions in system property as :

overcome ssl handshake error

System.setProperty("https.protocols", "TLSv1,TLSv1.1,TLSv1.2");

Agile is commonly regarded as an umbrella term. Scrum/Kanban are executions of Agile guiding principles from a project management perspective, whereas eXtreme Programming (XP) focuses on the engineering practices e.g., Unit Testing, Continuous Integration, Pair Programming etc.

Typically: Agile = Scrum + XP

Try to do <a href="#" class="arrow"> instead. (Note the sharp # character).

If you are using eclipse there is a "Skip Tests" checkbox on the configuration page.

Ultimately you always have a finite max of heap to use no matter what platform you are running on. In Windows 32 bit this is around 2GB (not specifically heap but total amount of memory per process). It just happens that Java chooses to make the default smaller (presumably so that the programmer can't create programs that have runaway memory allocation without running into this problem and having to examine exactly what they are doing).

So this given there are several approaches you could take to either determine what amount of memory you need or to reduce the amount of memory you are using. One common mistake with garbage collected languages such as Java or C# is to keep around references to objects that you no longer are using, or allocating many objects when you could reuse them instead. As long as objects have a reference to them they will continue to use heap space as the garbage collector will not delete them.

In this case you can use a Java memory profiler to determine what methods in your program are allocating large number of objects and then determine if there is a way to make sure they are no longer referenced, or to not allocate them in the first place. One option which I have used in the past is "JMP" http://www.khelekore.org/jmp/.

If you determine that you are allocating these objects for a reason and you need to keep around references (depending on what you are doing this might be the case), you will just need to increase the max heap size when you start the program. However, once you do the memory profiling and understand how your objects are getting allocated you should have a better idea about how much memory you need.

In general if you can't guarantee that your program will run in some finite amount of memory (perhaps depending on input size) you will always run into this problem. Only after exhausting all of this will you need to look into caching objects out to disk etc. At this point you should have a very good reason to say "I need Xgb of memory" for something and you can't work around it by improving your algorithms or memory allocation patterns. Generally this will only usually be the case for algorithms operating on large datasets (like a database or some scientific analysis program) and then techniques like caching and memory mapped IO become useful.

You don't really need to do anything manually, await keyword pauses the function execution until blah() returns.

private async void SomeFunction()
{
     var x = await LoadBlahBlah(); <- Function is not paused
     //rest of the code get's executed even if LoadBlahBlah() is still executing
}

private async Task<T> LoadBlahBlah()
{
     await DoStuff();  <- function is paused
     await DoMoreStuff();
}

T is type of object blah() returns

You can't really await a void function so LoadBlahBlah() cannot be void

The FormData class does work, however in iOS Safari (on the iPhone at least) I wasn't able to use Raphael Schweikert's solution as is.

Mozilla Dev has a nice page on manipulating FormData objects.

So, add an empty form somewhere in your page, specifying the enctype:

<form enctype="multipart/form-data" method="post" name="fileinfo" id="fileinfo"></form>

Then, create FormData object as:

var data = new FormData($("#fileinfo"));

and proceed as in Raphael's code.

You can also try the following project that aims to help use that api. It's here:https://github.com/MathiasSeguy-Android2EE/GDirectionsApiUtils

How it works, definitly simply:

public class MainActivity extends ActionBarActivity implements DCACallBack{
/**
 * Get the Google Direction between mDevice location and the touched location using the     Walk
 * @param point
 */
private void getDirections(LatLng point) {
     GDirectionsApiUtils.getDirection(this, mDeviceLatlong, point,     GDirectionsApiUtils.MODE_WALKING);
}

/*
 * The callback
 * When the direction is built from the google server and parsed, this method is called and give you the expected direction
 */
@Override
public void onDirectionLoaded(List<GDirection> directions) {        
    // Display the direction or use the DirectionsApiUtils
    for(GDirection direction:directions) {
        Log.e("MainActivity", "onDirectionLoaded : Draw GDirections Called with path " + directions);
        GDirectionsApiUtils.drawGDirection(direction, mMap);
    }
}

You can both remove row names and convert them to a column by reference (without reallocating memory using ->) using setDT and its keep.rownames = TRUE argument from the data.table package

library(data.table)
setDT(df, keep.rownames = TRUE)[]
#    rn     VALUE  ABS_CALL DETECTION     P.VALUE
# 1:  1 1007_s_at  957.7292         P 0.004862793
# 2:  2   1053_at  320.6327         P 0.031335632
# 3:  3    117_at  429.8423         P 0.017000453
# 4:  4    121_at 2395.7364         P 0.011447358
# 5:  5 1255_g_at  116.4936         A 0.397993682
# 6:  6   1294_at  739.9271         A 0.066864977

As mentioned by @snoram, you can give the new column any name you want, e.g. setDT(df, keep.rownames = "newname") would add "newname" as the rows column.

To have newline in code you use _

Example:

Dim a As Integer
a = 500 _
  + 80 _
  + 90

MsgBox a

Logical operators for boolean indexing in Pandas

It's important to realize that you cannot use any of the Python logical operators (and, or or not) on pandas.Series or pandas.DataFrames (similarly you cannot use them on numpy.arrays with more than one element). The reason why you cannot use those is because they implicitly call bool on their operands which throws an Exception because these data structures decided that the boolean of an array is ambiguous:

>>> import numpy as np
>>> import pandas as pd
>>> arr = np.array([1,2,3])
>>> s = pd.Series([1,2,3])
>>> df = pd.DataFrame([1,2,3])
>>> bool(arr)
ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()
>>> bool(s)
ValueError: The truth value of a Series is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().
>>> bool(df)
ValueError: The truth value of a DataFrame is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().

I did cover this more extensively in my answer to the "Truth value of a Series is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all()" Q+A.

NumPys logical functions

However NumPy provides element-wise operating equivalents to these operators as functions that can be used on numpy.array, pandas.Series, pandas.DataFrame, or any other (conforming) numpy.array subclass:

• and has np.logical_and
• or has np.logical_or
• not has np.logical_not
• numpy.logical_xor which has no Python equivalent but is a logical "exclusive or" operation

So, essentially, one should use (assuming df1 and df2 are pandas DataFrames):

np.logical_and(df1, df2)
np.logical_or(df1, df2)
np.logical_not(df1)
np.logical_xor(df1, df2)

Bitwise functions and bitwise operators for booleans

However in case you have boolean NumPy array, pandas Series, or pandas DataFrames you could also use the element-wise bitwise functions (for booleans they are - or at least should be - indistinguishable from the logical functions):

• bitwise and: np.bitwise_and or the & operator
• bitwise or: np.bitwise_or or the | operator
• bitwise not: np.invert (or the alias np.bitwise_not) or the ~ operator
• bitwise xor: np.bitwise_xor or the ^ operator

Typically the operators are used. However when combined with comparison operators one has to remember to wrap the comparison in parenthesis because the bitwise operators have a higher precedence than the comparison operators:

(df1 < 10) | (df2 > 10)  # instead of the wrong df1 < 10 | df2 > 10

This may be irritating because the Python logical operators have a lower precendence than the comparison operators so you normally write a < 10 and b > 10 (where a and b are for example simple integers) and don't need the parenthesis.

Differences between logical and bitwise operations (on non-booleans)

It is really important to stress that bit and logical operations are only equivalent for boolean NumPy arrays (and boolean Series & DataFrames). If these don't contain booleans then the operations will give different results. I'll include examples using NumPy arrays but the results will be similar for the pandas data structures:

>>> import numpy as np
>>> a1 = np.array([0, 0, 1, 1])
>>> a2 = np.array([0, 1, 0, 1])

>>> np.logical_and(a1, a2)
array([False, False, False,  True])
>>> np.bitwise_and(a1, a2)
array([0, 0, 0, 1], dtype=int32)

And since NumPy (and similarly pandas) does different things for boolean (Boolean or “mask” index arrays) and integer (Index arrays) indices the results of indexing will be also be different:

>>> a3 = np.array([1, 2, 3, 4])

>>> a3[np.logical_and(a1, a2)]
array([4])
>>> a3[np.bitwise_and(a1, a2)]
array([1, 1, 1, 2])

Summary table

Logical operator | NumPy logical function | NumPy bitwise function | Bitwise operator
-------------------------------------------------------------------------------------
       and       |  np.logical_and        | np.bitwise_and         |        &
-------------------------------------------------------------------------------------
       or        |  np.logical_or         | np.bitwise_or          |        |
-------------------------------------------------------------------------------------
                 |  np.logical_xor        | np.bitwise_xor         |        ^
-------------------------------------------------------------------------------------
       not       |  np.logical_not        | np.invert              |        ~

Where the logical operator does not work for NumPy arrays, pandas Series, and pandas DataFrames. The others work on these data structures (and plain Python objects) and work element-wise. However be careful with the bitwise invert on plain Python bools because the bool will be interpreted as integers in this context (for example ~False returns -1 and ~True returns -2).
