You could do $stmt->queryString to obtain the SQL query used in the statement. If you want to save the entire $stmt variable (I can't see why), you could just copy it. It is an instance of PDOStatement so there is apparently no advantage in storing it.

If you are using spring boot then add these tags in pom.xml.

<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
</plugin>

and

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    `<maven.compiler.release>`10</maven.compiler.release>
</properties>

You can change java version to 11 or 13 as well in <maven.compiler.release> tag.

Just add below tags in pom.xml

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    <maven.compiler.release>11</maven.compiler.release>
</properties>

You can change the 11 to 10, 13 as well to change java version. I am using java 13 which is latest. It works for me.

Enable Multidex through build.gradle of your app module

multiDexEnabled true

Same as below -

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "com.xx.xxx"
        minSdkVersion 15
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        multiDexEnabled true //Add this
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            shrinkResources true
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

Then follow below steps -

1. From the Build menu -> press the Clean Project button.
2. When task completed, press the Rebuild Project button from the Build menu.
3. From menu File -> Invalidate cashes / Restart

compile is now deprecated so it's better to use implementation or api

If none of your routes contain closures, but you are still getting this error, please check

routes/api.php

Laravel has a default auth api route in the above file.

Route::middleware('auth:api')->get('/user', function (Request $request) {
    return $request->user();
});

which can be commented or replaced with a call to controller method if required.

You can also run docker build with -f option

docker build -t ubuntu-test:latest -f Dockerfile.custom .

spring.jpa.hibernate.ddl-auto = update

change update to create, and run it

after run safely again change create to update so again all tables will not create and you can use your previous data

Upgrading to Tensorflow 2.0 using pip. Requires Python > 3.4 and pip >= 19.0

CST:~ USERX$ pip3 show tensorflow
Name: tensorflow
Version: 1.13.1

CST:~ USERX$ python3 --version
Python 3.7.3

CST:~ USERX$ pip3 install --upgrade tensorflow

CST:~ USERX$ pip3 show tensorflow
Name: tensorflow
Version: 2.0.0

Solved! The call build job: project, parameters: params fails with an error java.lang.UnsupportedOperationException: must specify $class with an implementation of interface java.util.List when params = [:]. Replacing it with params = null solved the issue. Here the working code below.

def doCopyMibArtefactsHere(projectName) {
    step ([
        $class: 'CopyArtifact',
        projectName: projectName,
        filter: '**/**.mib',
        fingerprintArtifacts: true, 
        flatten: true
    ]);
}

def BuildAndCopyMibsHere(projectName, params = null) {
    build job: project, parameters: params
    doCopyMibArtefactsHere(projectName)
}
node { 
    stage('Prepare Mib'){
        BuildAndCopyMibsHere('project1')
    }
}

I had similar issues when migrating to androidx.

If by adding the below two lines to gradle.properties did not solve the issue

android.useAndroidX=true
android.enableJetifier=true

Then try

1. With Android Studio 3.2 and higher, you can migrate an existing project to AndroidX by selecting Refactor > Migrate to AndroidX from the menu bar (developer.android.com)

If you still run into issues with migration then manually try to replace the libraries which are causing the issue.

For example

If you have an issue with android.support.annotation.NonNull change it to androidx.annotation.NonNull as indicated in the below class mappings table.

Class Mappings

Maven Artifact Mappings

Look this http://iswift.org/cookbook/compare-2-dates

Get Dates:

// Get current date
let dateA = NSDate()

// Get a later date (after a couple of milliseconds)
let dateB = NSDate()

Using SWITCH Statement

// Compare them
switch dateA.compare(dateB) {
    case .OrderedAscending     :   print("Date A is earlier than date B")
    case .OrderedDescending    :   print("Date A is later than date B")
    case .OrderedSame          :   print("The two dates are the same")
}

using IF Statement

 if dateA.compare(dateB) == .orderedAscending {
     datePickerTo.date = datePicker.date
 }

 //OR

 if case .orderedAcending = dateA.compare(dateB) {

 }

If you are using debug configuration for maven, use the command

clean install

And skip all the tests.

model.predict() expects the first parameter to be a numpy array. You supply a list, which does not have the shape attribute a numpy array has.

Otherwise your code looks fine, except that you are doing nothing with the prediction. Make sure you store it in a variable, for example like this:

prediction = model.predict(np.array(tk.texts_to_sequences(text)))
print(prediction)

Migrate to androidX library

With Android Studio 3.2 and higher, you can migrate an existing project to AndroidX by selecting Refactor > Migrate to AndroidX from the menu bar.

Source: https://developer.android.com/jetpack/androidx/migrate

Solution:
1. sudo apt remove python-pip
2. pip3 install pip (or install pip by get-pip.py)

Why:
This error occurred on pip 8.0.1 which installed by apt-get. And happened only when your network is unstable.

If you have a pip installed with apt, it hides the pip you installed by other ways, so you should remove the apt one first.

I disconnected the network and tested 8.0.1, 9.0.3, 10.x the 3 versions installed with pip3 or get-pip.py, no error occurred.   So, I think only the apt version of pip 8.0.1 has that bug, the others is ok.

For me Upgrading Gradle works.Look for update at Android Website then add it in your build.gradle (Project) like this

 dependencies {
        classpath 'com.android.tools.build:gradle:2.2.0-alpha4'   
          ....
    }

then sync project with gradle file plus it might be happened sometimes because of java.exe (in my case) just force kill java.exe from task manager in windows then re run program

In my case, I had to do the following while running with Junit5

@SpringBootTest(classes = {abc.class}) @ExtendWith(SpringExtension.class

Here abc.class was the class that was being tested

It works if you remove flexDirection: row from descriptionContainerVer and descriptionContainerVer2 respectively.

UPDATE (see comments)

I made a few changes to achieve what I think you're after. First of all I removed the descriptionContainerHor component. Then I set the flexDirection of the vertical views to row and added alignItems: 'center' and justifyContent: 'center'. Since the vertical views are now in fact stacked along the horizontal axis I removed the Ver part from the name.

So now you have a wrapper view that should vertically and horizontally align it's content and stack it along the x-axis. I then simply put two invisible View components on the left and right side of the Text component to do the padding.

Like this:

<View style={styles.descriptionContainer}>
  <View style={styles.padding}/>
    <Text style={styles.descriptionText} numberOfLines={5} >
      Here is a really long text that you can do nothing about, its gonna be long wether you like it or not, so be prepared for it to go off screen. Right? Right..!
    </Text>
  <View style={styles.padding}/>
</View>

And this:

descriptionContainer:{
  flex:0.5, //height (according to its parent),
  flexDirection: 'row',
  backgroundColor: 'blue',
  alignItems: 'center',
  justifyContent: 'center',
  // alignSelf: 'center',
},
padding: {
  flex: 0.1
},
descriptionText: {
  backgroundColor: 'green',//Colors.transparentColor,
  fontSize: 16,
  flex: 0.8,
  color: 'white',
  textAlign: 'center',
  flexWrap: 'wrap'
},

Then you get what I believe you were after.

FURTHER IMPROVEMENTS

Now if you would like to stack multiple text areas within the blue and orange views you can do something like this:

<View style={styles.descriptionContainer2}>
  <View style={styles.padding}/>
  <View style={styles.textWrap}>
    <Text style={styles.descriptionText} numberOfLines={5} >
      Some other long text which you can still do nothing about.. Off the screen we go then.
    </Text>
    <Text style={styles.descriptionText} numberOfLines={5} >
      Another column of text.
    </Text>
  </View>
  <View style={styles.padding}/>
</View>

Where textWrapis styled like this:

textWrap: {
  flexDirection: 'column',
  flex: 0.8
},

Hope this helps!

Another possible reason

resConfigs "hdpi", "xhdpi", "xxhdpi", "xxxhdpi"

can be source of this issue

This solved my problem. Add below to your system path

PATH_TO_android\platforms

PATH_TO_android\platform-tools

On Linux or Ubuntu you need to use the complete path.

For example

/home/ubuntu/.android/keystorname.keystore

In my case I was using ~ instead of /home/user/. Using shorthands like the below does not work

~/.android/keystorname.keystore
./keystorename.keystore

I got this error with a mis-configured test event. I changed the source buckets ARN but forgot to edit the default S3 bucket name.

I.e. make sure that in the bucket section of the test event both the ARN and bucket name are set correctly:

"bucket": {
  "arn": "arn:aws:s3:::your_bucket_name",
  "name": "your_bucket_name",
  "ownerIdentity": {
    "principalId": "EXAMPLE"
  }

Make sure you run the command

docker build . -t docker-whale 

from the directory that has the dockerfile

This happened to me when my package name wasn't represented in the google-services.json file I downloaded. Open your google-services.json file and make sure there is a client_info object that has a package name that corresponds to your manifests package name.

Make sure the package name in your project manifest is exactly the same in google-services.json file

thanks.

Try installing via :app:installDebug. If it works then it is related to Android Studio's caches. I removed .gradle/ folder inside my project and it works.

had the same issue as described by @scottyab.

all references were 8.4.0 but it failed due to a reference to app-measurement 8.3.0 that i did not reference anywhere (but one of the dependencies?). you can see the problem if you hover over the bad(red) dependency in Android Studio. explicitly adding

compile 'com.google.android.gms:play-services-measurement:8.4.0'

to app.gradle solved the issue.

The SciPy installation page already recommends several ways of installing python with SciPy already included, such as WinPython.

Another way is to use wheels (a built-package format):

pip install SomePackage-1.0-py2.py3-none-any.whl

The wheel packages you can find on: http://www.lfd.uci.edu/~gohlke/pythonlibs/

For SciPy you need:

• the NumPy wheel packages
• and the SciPy wheel packages

I was having the problem as a beginner..........

There was issue in the path of the xml file I have saved.

var soundEffect = AVAudioPlayer()

func playSound(_ buttonTag : Int){

    let path = Bundle.main.path(forResource: "note\(buttonTag)", ofType : "wav")!
    let url = URL(fileURLWithPath : path)

    do{
        soundEffect = try AVAudioPlayer(contentsOf: url)
        soundEffect?.play()
        // to stop the spound .stop()
    }catch{
        print ("file could not be loaded or other error!")
    }
}

works in swift 4 latest version. ButtonTag would be a tag on a button on your interface. Notes are in a folder in a folder parallel to Main.storyboard. Every note is named as note1, note2, etc. ButtonTag is giving the number 1, 2, etc from the button clicked which is passed as param

2018

The "android" command is deprecated.

try

sdkmanager "build-tools;27.0.3"

This work for me, as #Fadhil said

This is due to adding an image in drawable which has some extension like (.jpg), and you have changed or saved that to a .png format (this error will occur while changing the image format manually without using an editor tool).

Android Studio will throws an error while compiling the resource package using AAPT (Android Asset Packaging Tool), so all you need to do is use some image editor tools like GIMP or Paint to save the extension accordingly. Rebuild your project once everything is done.

For example: open your image in Paint (drag and drop your image to open it) ? menu File ? Save As ? Save as Type ? select your required type from the dropdown like I have shown in the below pictures:

In /etc/my.cnf add:

  max_allowed_packet=32M

It worked for me. You can verify by going into PHPMyAdmin and opening a SQL command window and executing:

SHOW VARIABLES LIKE  'max_allowed_packet'

In my case my problem was that I was using an older version of NetBeans. The Maven repository removed an http reference, but the embedded Maven in Netbeans had that http reference hard-coded. I was really confused at first because my pom.xml referenced the proper https://repo.maven.apache.org/maven2.

Fixing it was pretty simple. I downloaded the latest zip archive of Maven from the following location and extracted it to my machine: https://maven.apache.org/download.cgi

Within Netbeans at Tools -> Options -> Java -> Maven on the "Execution" section I set "Maven Home" to the newly extracted zip file location.

Now I could build my project....

if your app transfer other account. You should rearrange Signing section for the corrcet team(new team)

I had the same problem. This issue worked for me. In storyboard select your table view and change it from static cells into dynamic cells.

It must have been a problem with my Java install. I removed all traces of Java (C://program files/Java/jdk) and jre folders and reinstalled it from the official page and now it works fine.

@delato468 comment must be listed as a solution as it worked for me.

In addition to defining the parameter, the user must pass it too at the time of calling the function

fetch_data(PDO $pdo, $cat_id)

TL;DR: Scan down to image, and then check out working project here.

Updating my answer for a simpler solution that I found..

In my case, I wanted to fix the width, and have variable height cells. I wanted a drop in, reusable solution that handled rotation and didn't require a lot of intervention.

What I arrived at, was override (just) systemLayoutFitting(...) in the collection cell (in this case a base class for me), and first defeat UICollectionView's effort to set the wrong dimension on contentView by adding a constraint for the known dimension, in this case, the width.

class EstimatedWidthCell: UICollectionViewCell {
    override init(frame: CGRect) {
        super.init(frame: frame)
        contentView.translatesAutoresizingMaskIntoConstraints = false
    }

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        contentView.translatesAutoresizingMaskIntoConstraints = false
    }

    override func systemLayoutSizeFitting(
        _ targetSize: CGSize, withHorizontalFittingPriority
        horizontalFittingPriority: UILayoutPriority,
        verticalFittingPriority: UILayoutPriority) -> CGSize {

        width.constant = targetSize.width

and then return the final size for the cell - used for (and this feels like a bug) the dimension of the cell itself, but not contentView - which is otherwise constrained to a conflicting size (hence the constraint above). To calculate the correct cell size, I use a lower priority for the dimension that I wanted to float, and I get back the height required to fit the content within the width to which I want to fix:

        let size = contentView.systemLayoutSizeFitting(
            CGSize(width: targetSize.width, height: 1),
            withHorizontalFittingPriority: .required,
            verticalFittingPriority: verticalFittingPriority)

        print("\(#function) \(#line) \(targetSize) -> \(size)")
        return size
    }

    lazy var width: NSLayoutConstraint = {
        return contentView.widthAnchor
            .constraint(equalToConstant: bounds.size.width)
            .isActive(true)
    }()
}

But where does this width come from? It is configured via the estimatedItemSize on the collection view's flow layout:

lazy var collectionView: UICollectionView = {
    let view = UICollectionView(frame: CGRect(), collectionViewLayout: layout)
    view.backgroundColor = .cyan
    view.translatesAutoresizingMaskIntoConstraints = false
    return view
}()

lazy var layout: UICollectionViewFlowLayout = {
    let layout = UICollectionViewFlowLayout()
    let width = view.bounds.size.width // should adjust for inset
    layout.estimatedItemSize = CGSize(width: width, height: 10)
    layout.scrollDirection = .vertical
    return layout
}()

Finally, to handle rotation, I implement trailCollectionDidChange to invalidate the layout:

override func traitCollectionDidChange(_ previousTraitCollection: UITraitCollection?) {
    layout.estimatedItemSize = CGSize(width: view.bounds.size.width, height: 10)
    layout.invalidateLayout()
    super.traitCollectionDidChange(previousTraitCollection)
}

The final result looks like this:

And I have published a working sample here.

Looks like the initial problem is with the auto-config.

If you don't need the datasource, simply remove it from the auto-config process:

@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})

Center in container

The code below does the same thing as centering in the Interface Builder.

override func viewDidLoad() {
    super.viewDidLoad()

    // set up the view
    let myView = UIView()
    myView.backgroundColor = UIColor.blue
    myView.translatesAutoresizingMaskIntoConstraints = false
    view.addSubview(myView)

    // Add code for one of the constraint methods below
    // ...
}

Method 1: Anchor Style

myView.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
myView.centerYAnchor.constraint(equalTo: view.centerYAnchor).isActive = true

Method 2: NSLayoutConstraint Style

NSLayoutConstraint(item: myView, attribute: NSLayoutConstraint.Attribute.centerX, relatedBy: NSLayoutConstraint.Relation.equal, toItem: view, attribute: NSLayoutConstraint.Attribute.centerX, multiplier: 1, constant: 0).isActive = true
NSLayoutConstraint(item: myView, attribute: NSLayoutConstraint.Attribute.centerY, relatedBy: NSLayoutConstraint.Relation.equal, toItem: view, attribute: NSLayoutConstraint.Attribute.centerY, multiplier: 1, constant: 0).isActive = true

Notes

• Anchor style is the preferred method over NSLayoutConstraint Style, however it is only available from iOS 9, so if you are supporting iOS 8 then you should still use NSLayoutConstraint Style.
• You will also need to add length and width constraints.
• My full answer is here.

Use a SmartInitializingSingleton bean in spring > 4.1

@Bean
public SmartInitializingSingleton importProcessor() {
    return () -> {
        doStuff();
    };

}

As alternative a CommandLineRunner bean can be implemented or annotating a bean method with @PostConstruct.

This particular error has very little to do with the actual error. Here is my similar experience and the solution...

I had a table that I use in my statement with |database-name|.login composite name. I thought this wouldn't be a problem. It was the problem indeed. Enclosing it inside square brackets solved my problem ([|database-name|].[login]). So, the problem is MySQL preserved words (other way around)... make sure your columns too are not failing to this type of error scenario...

You should use Array.prototype.reduce to do this. I did do a little JS perf test to verify that this is more performant than doing a .filter + .map.

$scope.appIds = $scope.applicationsHere.reduce(function(ids, obj){
    if(obj.selected === true){
        ids.push(obj.id);
    }
    return ids;
}, []);

Just for the sake of clarity, here's the sample .reduce I used in the JSPerf test:

  var things = [_x000D_
    {id: 1, selected: true},_x000D_
    {id: 2, selected: true},_x000D_
    {id: 3, selected: true},_x000D_
    {id: 4, selected: true},_x000D_
    {id: 5, selected: false},_x000D_
    {id: 6, selected: true},_x000D_
    {id: 7, selected: false},_x000D_
    {id: 8, selected: true},_x000D_
    {id: 9, selected: false},_x000D_
    {id: 10, selected: true},_x000D_
  ];_x000D_
  _x000D_
   _x000D_
var ids = things.reduce((ids, thing) => {_x000D_
  if (thing.selected) {_x000D_
    ids.push(thing.id);_x000D_
  }_x000D_
  return ids;_x000D_
}, []);_x000D_
_x000D_
console.log(ids)

EDIT 1

Note, As of 2/2018 Reduce + Push is fastest in Chrome and Edge, but slower than Filter + Map in Firefox

Adding only android-support-v7-appcompat.jar to library dependencies is not enough, you have also to import in your project the module that you can find in your SDK at the path \android-sdk\extras\android\support\v7\appcompatand after that add module dependencies configuring the project structure in this way

otherwise are included only the class files of support library and the app is not able to load the other resources causing the error.

In addition as reVerse suggested replace this

public CustomActionBarDrawerToggle(Activity mActivity,
                                           DrawerLayout mDrawerLayout) {
            super(mActivity, mDrawerLayout,new Toolbar(MyActivity.this) ,
                    R.string.ns_menu_open, R.string.ns_menu_close);
        }

with

You have 4 options:

Using a certificate as parameter

$ pip install --cert /path/to/mycertificate.crt linkchecker

Using a certificate in a pip.conf

Create this file:

$HOME/.pip/pip.conf (Linux)

%HOME%\pip\pip.ini (Windows)

and add these lines:

[global]
cert = /path/to/mycertificate.crt

Ignoring certificate and using HTTP

$ pip install --trusted-host pypi.python.org linkchecker

Ignoring certificate and using HTTP in a pip.conf

For completion's sake, here's the snippet that creates the transport client using proper static method provided by InetSocketTransportAddress:

    Client esClient = TransportClient.builder()
        .settings(settings)
        .build()
        .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("143.79.236.xxx"), 9300));

Also, after you've updated your repository ids, make sure you run clean as release:prepare will pick up where it left off. So you can do:

mvn release:prepare -Dresume=false or

mvn release:clean release:prepare

For me, I was missing @ActiveProfile at my test class

@ActiveProfiles("sandbox")
class MyTestClass...

Have a look at the documentation. You made the following mistakes. Firstly, ps.executeQuery() doesn't have any parameters. Instead you passed the SQL query into it.

Secondly, regarding the prepared statement, you have to use the ? symbol if want to pass any parameters. And later bind it using

setXXX(index, value) 

Here xxx stands for the data type.

This seems to be due to a problem in the UITableViewController subclass template. It comes with a version of the prepareForSegue method that would require you to unwrap the segue.

Replace your current prepareForSegue function with:

override func prepareForSegue(segue: UIStoryboardSegue!, sender: AnyObject!) {
    if (segue.identifier == "Load View") {
        // pass data to next view
    }
}

This version implicitly unwraps the parameters, so you should be fine.

I set .navbar-brand { min-height: inherit } which solved the issue for me (thanks @creimers for inspiration).

Override service method like this:

protected void service(HttpServletRequest request, HttpServletResponse   response) throws ServletException, IOException {
        doPost(request, response);
}

And Voila!

For the sake of other developers who finds this question and need another solution that fits not only for unit-tests:

I've found this on a blog (not my solution! Credit to the blog's owner).

TrustStrategy acceptingTrustStrategy = (X509Certificate[] chain, String authType) -> true;

SSLContext sslContext = org.apache.http.ssl.SSLContexts.custom()
        .loadTrustMaterial(null, acceptingTrustStrategy)
        .build();

SSLConnectionSocketFactory csf = new SSLConnectionSocketFactory(sslContext);

CloseableHttpClient httpClient = HttpClients.custom()
        .setSSLSocketFactory(csf)
        .build();

HttpComponentsClientHttpRequestFactory requestFactory =
        new HttpComponentsClientHttpRequestFactory();

requestFactory.setHttpClient(httpClient);

RestTemplate restTemplate = new RestTemplate(requestFactory);

When you really want to write an i-test for a spring data repository you can do it like this:

@RunWith(SpringRunner.class)
@DataJpaTest
@EnableJpaRepositories(basePackageClasses = WebBookingRepository.class)
@EntityScan(basePackageClasses = WebBooking.class)
public class WebBookingRepositoryIntegrationTest {

    @Autowired
    private WebBookingRepository repository;

    @Test
    public void testSaveAndFindAll() {
        WebBooking webBooking = new WebBooking();
        webBooking.setUuid("some uuid");
        webBooking.setItems(Arrays.asList(new WebBookingItem()));
        repository.save(webBooking);

        Iterable<WebBooking> findAll = repository.findAll();

        assertThat(findAll).hasSize(1);
        webBooking.setId(1L);
        assertThat(findAll).containsOnly(webBooking);
    }
}

To follow this example you have to use these dependencies:

<dependency>
    <groupId>com.h2database</groupId>
    <artifactId>h2</artifactId>
    <version>1.4.197</version>
    <scope>test</scope>

getaddrinfo ENOTFOUND means client was not able to connect to given address. Please try specifying host without http:

var optionsget = {
    host : 'localhost',
    port : 3010,
    path : '/quote/random', // the rest of the url with parameters if needed
    method : 'GET' // do GET
};

Regarding learning resources, you won't go wrong if you start with http://www.nodebeginner.org/ and then go through some good book to get more in-depth knowledge - I recommend Professional Node.js , but there's many out there.

Using Query parameter

<a href="edit.jsp?userId=${user.id}" />  

Using Hidden variable .

<form method="post" action="update.jsp">  
...  
   <input type="hidden" name="userId" value="${user.id}">  

you can send Using Session object.

   session.setAttribute("userId", userid);

These values will now be available from any jsp as long as your session is still active.

   int userid = session.getAttribute("userId"); 

I resolved this problem by following steps:

1. Right click on root folder of project.
2. Goto properties
3. Click web in left menu
4. change current port http://localhost:####/
5. click create virtual directory
6. Save the changes (ctrl+s)
7. Run

I had a similar issue, and found I was simply missing a dependency (libssl-dev, for me). As referenced in https://cryptography.io/en/latest/installation/, ensure that all dependencies are met:

On Windows

If you’re on Windows you’ll need to make sure you have OpenSSL installed. There are pre-compiled binaries available. If your installation is in an unusual location set the LIB and INCLUDE environment variables to include the corresponding locations. For example:

C:\> \path\to\vcvarsall.bat x86_amd64
C:\> set LIB=C:\OpenSSL-1.0.1f-64bit\lib;%LIB%
C:\> set INCLUDE=C:\OpenSSL-1.0.1f-64bit\include;%INCLUDE%
C:\> pip install cryptography

Building cryptography on Linux

cryptography should build very easily on Linux provided you have a C compiler, headers for Python (if you’re not using pypy), and headers for the OpenSSL and libffi libraries available on your system.

For Debian and Ubuntu, the following command will ensure that the required dependencies are installed:

sudo apt-get install build-essential libssl-dev libffi-dev python-dev

For Fedora and RHEL-derivatives, the following command will ensure that the required dependencies are installed:

sudo yum install gcc libffi-devel python-devel OpenSSL-devel

You should now be able to build and install cryptography with the usual.

pip install cryptography

Firebug as Firefox (FF) extension is currently (as per 01/2017) the only way to debug direct javascript responses from AJAX calls. Unfortunately, it's development is discontinued. And since Firefox 50, the Firebug also cannot be installed anymore due to compatability issues :-( They kind of emulated FF developer tools UI to recall Firebug UI in some way.

Unfortunatelly, FF native developer tools are not able to debug javascript returned directly by AJAX calls. Same applies to Chrome devel. tools.

I must have disabled upgrades of FF due to this issue, since I badly need to debug JS from XHR calls on current project. So not good news here - let's hope the feature to debug direct JS responses will be incorporated into FF/Chrome developer tools soon.

I think somewhere in your codebase are you @Autowiring the concrete class ServiceImpl where you should be autowiring it's interface (presumably MyService).

I faced difficulties using "window.URL" with Opera Browser as it would result to "undefined". Also, with window.URL, the PDF document never opened in Internet Explorer and Microsoft Edge (it would remain waiting forever). I came up with the following solution that works in IE, Edge, Firefox, Chrome and Opera (have not tested with Safari):

$http.post(postUrl, data, {responseType: 'arraybuffer'})
.success(success).error(failed);

function success(data) {
   openPDF(data.data, "myPDFdoc.pdf");
};

function failed(error) {...};

function openPDF(resData, fileName) {
    var ieEDGE = navigator.userAgent.match(/Edge/g);
    var ie = navigator.userAgent.match(/.NET/g); // IE 11+
    var oldIE = navigator.userAgent.match(/MSIE/g); 

    var blob = new window.Blob([resData], { type: 'application/pdf' });

    if (ie || oldIE || ieEDGE) {
       window.navigator.msSaveBlob(blob, fileName);
    }
    else {
       var reader = new window.FileReader();
       reader.onloadend = function () {
          window.location.href = reader.result;
       };
       reader.readAsDataURL(blob);
    }
}

Let me know if it helped! :)

On the Unity Editor open your project and:

1. Enable External option in Unity ? Preferences ? Packages ? Repository (only if Unity ver < 4.5)
2. Switch to Visible Meta Files in Edit ? Project Settings ? Editor ? Version Control Mode
3. Switch to Force Text in Edit ? Project Settings ? Editor ? Asset Serialization Mode
4. Save Scene and Project from File menu.
5. Quit Unity and then you can delete the Library and Temp directory in the project directory. You can delete everything but keep the Assets and ProjectSettings directory.

If you already created your empty git repo on-line (eg. github.com) now it's time to upload your code. Open a command prompt and follow the next steps:

cd to/your/unity/project/folder

git init

git add *

git commit -m "First commit"

git remote add origin [email protected]:username/project.git

git push -u origin master

You should now open your Unity project while holding down the Option or the Left Alt key. This will force Unity to recreate the Library directory (this step might not be necessary since I've seen Unity recreating the Library directory even if you don't hold down any key).

Finally have git ignore the Library and Temp directories so that they won’t be pushed to the server. Add them to the .gitignore file and push the ignore to the server. Remember that you'll only commit the Assets and ProjectSettings directories.

And here's my own .gitignore recipe for my Unity projects:

# =============== #
# Unity generated #

Use data type LONGBLOB instead of BLOB in your database table.

st.executeUpdate(sql);

Just for others getting this error and looking for info on it, it is also thrown if you happen to pass a binding parameter and then never use it. I couldn't really find that stated clearly anywhere but had to prove it through trial and error.

A. Grab file data from the file field

The first thing to do is bind a function to the change event on your file field and a function for grabbing the file data:

// Variable to store your files
var files;

// Add events
$('input[type=file]').on('change', prepareUpload);

// Grab the files and set them to our variable
function prepareUpload(event)
{
  files = event.target.files;
}

This saves the file data to a file variable for later use.

B. Handle the file upload on submit

When the form is submitted you need to handle the file upload in its own AJAX request. Add the following binding and function:

$('form').on('submit', uploadFiles);

// Catch the form submit and upload the files
function uploadFiles(event)
{
  event.stopPropagation(); // Stop stuff happening
    event.preventDefault(); // Totally stop stuff happening

// START A LOADING SPINNER HERE

// Create a formdata object and add the files
var data = new FormData();
$.each(files, function(key, value)
{
    data.append(key, value);
});

$.ajax({
    url: 'submit.php?files',
    type: 'POST',
    data: data,
    cache: false,
    dataType: 'json',
    processData: false, // Don't process the files
    contentType: false, // Set content type to false as jQuery will tell the server its a query string request
    success: function(data, textStatus, jqXHR)
    {
        if(typeof data.error === 'undefined')
        {
            // Success so call function to process the form
            submitForm(event, data);
        }
        else
        {
            // Handle errors here
            console.log('ERRORS: ' + data.error);
        }
    },
    error: function(jqXHR, textStatus, errorThrown)
    {
        // Handle errors here
        console.log('ERRORS: ' + textStatus);
        // STOP LOADING SPINNER
    }
});
}

What this function does is create a new formData object and appends each file to it. It then passes that data as a request to the server. 2 attributes need to be set to false:

• processData - Because jQuery will convert the files arrays into strings and the server can't pick it up.
• contentType - Set this to false because jQuery defaults to application/x-www-form-urlencoded and doesn't send the files. Also setting it to multipart/form-data doesn't seem to work either.

C. Upload the files

Quick and dirty php script to upload the files and pass back some info:

<?php // You need to add server side validation and better error handling here

$data = array();

if(isset($_GET['files']))
{  
$error = false;
$files = array();

$uploaddir = './uploads/';
foreach($_FILES as $file)
{
    if(move_uploaded_file($file['tmp_name'], $uploaddir .basename($file['name'])))
    {
        $files[] = $uploaddir .$file['name'];
    }
    else
    {
        $error = true;
    }
}
$data = ($error) ? array('error' => 'There was an error uploading your files') : array('files' => $files);
}
else
{
    $data = array('success' => 'Form was submitted', 'formData' => $_POST);
}

echo json_encode($data);

?>

IMP: Don't use this, write your own.

D. Handle the form submit

The success method of the upload function passes the data sent back from the server to the submit function. You can then pass that to the server as part of your post:

function submitForm(event, data)
{
  // Create a jQuery object from the form
$form = $(event.target);

// Serialize the form data
var formData = $form.serialize();

// You should sterilise the file names
$.each(data.files, function(key, value)
{
    formData = formData + '&filenames[]=' + value;
});

$.ajax({
    url: 'submit.php',
    type: 'POST',
    data: formData,
    cache: false,
    dataType: 'json',
    success: function(data, textStatus, jqXHR)
    {
        if(typeof data.error === 'undefined')
        {
            // Success so call function to process the form
            console.log('SUCCESS: ' + data.success);
        }
        else
        {
            // Handle errors here
            console.log('ERRORS: ' + data.error);
        }
    },
    error: function(jqXHR, textStatus, errorThrown)
    {
        // Handle errors here
        console.log('ERRORS: ' + textStatus);
    },
    complete: function()
    {
        // STOP LOADING SPINNER
    }
});
}

Final note

This script is an example only, you'll need to handle both server and client side validation and some way to notify users that the file upload is happening. I made a project for it on Github if you want to see it working.

As of Android Studio version 0.8.14

You should add:

 android {
     packagingOptions { 
         exclude 'META-INF/LICENSE.txt'
         exclude 'META-INF/NOTICE.txt'
         exclude '...'
     }
 }  

to your build.gradle file.

History:

According to comment 14 in this bug: https://issuetracker.google.com/issues/36982149#comment14 this is a bug in v0.7.0 of the Android Gradle plugin, and is due to be fixed soon in 0.7.1.

Here are the notes from that bug about the addition for 0.7.1:

0.7.1 is out with the fix for this.

The DSL to exclude files is:

android {
    packagingOptions {
        exclude 'META-INF/LICENSE.txt'
    }
}

You can add as many exclude statement as you want. The value is the archive path. No wildcard or glob support yet.

Filenames "LICENSE.txt" and "NOTICE.txt" are case sensitive. Please try out with "license.txt" and "notice.txt" as well.

You didn't bind all your bindings here

$sql = "SELECT SQL_CALC_FOUND_ROWS *, UNIX_TIMESTAMP(publicationDate) AS publicationDate     FROM comments WHERE articleid = :art 
ORDER BY " . mysqli_escape_string($order) . " LIMIT :numRows";

$st = $conn->prepare( $sql );
$st->bindValue( ":art", $art, PDO::PARAM_INT );

You've declared a binding called :numRows but you never actually bind anything to it.

UPDATE 2019: I keep getting upvotes on this and that reminded me of another suggestion

Double quotes are string interpolation in PHP, so if you're going to use variables in a double quotes string, it's pointless to use the concat operator. On the flip side, single quotes are not string interpolation, so if you've only got like one variable at the end of a string it can make sense, or just use it for the whole string.

In fact, there's a micro op available here since the interpreter doesn't care about parsing the string for variables. The boost is nearly unnoticable and totally ignorable on a small scale. However, in a very large application, especially good old legacy monoliths, there can be a noticeable performance increase if strings are used like this. (and IMO, it's easier to read anyway)

TL;DR Xcode is very particular about the name you give your App ID in the member center. Having the correct bundle identifier is not enough. You must use the specific format shown below for Xcode to "see" your App ID.

Update: According to @isaacselement in the comments below, this issue has been resolved in Xcode 7.3.1.

@romrom's solution of deleting the App ID and having Xcode create a new one was a clue. Unfortunately it was a nonstarter for me since my App ID was used by a Store app and therefore could not be deleted.

However, I discovered through some experimentation that I could solve the problem by manually editing the exiting App ID. It turns out that Xcode is really picky about the name of the ID, and not just the bundle ID.

For a typical bundle ID such as com.mycompany.appname, the App ID name must be in this format:

XC com mycompany appname

a name in any other format won't be seen by Xcode.

How to check if you're affected / How to Fix

1. Log in to the Member Center.
2. Click on "Certificates, Identifiers & Profiles".
3. One the left-hand navigation bar, click on "App IDs".
4. Locate the App ID with your bundle identifier.
5. If that App ID doesn't have the correct name format (as shown above), click on it then click the Edit button.
6. Change the name and click Done.
7. Enjoy the reduction in stress and anger.

P.S. There are some related problems if you're using Xcode 7.3 in which it won't automatically create proper distribution profiles for you, even if you fix the name as I mentioned above. The solution is to downgrade to 7.2.1 or 7.3 Beta or use a tool like fastlane/sigh.

The question is relatively old, but I hope this post still might be relevant for others.

TL;DR: use AlarmManager to schedule a task, use IntentService, see the sample code here;

What this test-application(and instruction) is about:

Simple helloworld app, which sends you notification every 2 hours. Clicking on notification - opens secondary Activity in the app; deleting notification tracks.

When should you use it:

Once you need to run some task on a scheduled basis. My own case: once a day, I want to fetch new content from server, compose a notification based on the content I got and show it to user.

What to do:

1. First, let's create 2 activities: MainActivity, which starts notification-service and NotificationActivity, which will be started by clicking notification:

   activity_main.xml

   <?xml version="1.0" encoding="utf-8"?>
   <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       android:padding="16dp">
       <Button
           android:id="@+id/sendNotifications"
           android:onClick="onSendNotificationsButtonClick"
           android:layout_width="wrap_content"
           android:layout_height="wrap_content"
           android:text="Start Sending Notifications Every 2 Hours!" />
   </RelativeLayout>
   

   MainActivity.java

   public class MainActivity extends AppCompatActivity {
       @Override
       protected void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
           setContentView(R.layout.activity_main);
       }
   
       public void onSendNotificationsButtonClick(View view) {
           NotificationEventReceiver.setupAlarm(getApplicationContext());
       }   
   }
   

   and NotificationActivity is any random activity you can come up with. NB! Don't forget to add both activities into AndroidManifest.

2. Then let's create WakefulBroadcastReceiver broadcast receiver, I called NotificationEventReceiver in code above.

   Here, we'll set up AlarmManager to fire PendingIntent every 2 hours (or with any other frequency), and specify the handled actions for this intent in onReceive() method. In our case - wakefully start IntentService, which we'll specify in the later steps. This IntentService would generate notifications for us.

   Also, this receiver would contain some helper-methods like creating PendintIntents, which we'll use later

   NB1! As I'm using WakefulBroadcastReceiver, I need to add extra-permission into my manifest: <uses-permission android:name="android.permission.WAKE_LOCK" />

   NB2! I use it wakeful version of broadcast receiver, as I want to ensure, that the device does not go back to sleep during my IntentService's operation. In the hello-world it's not that important (we have no long-running operation in our service, but imagine, if you have to fetch some relatively huge files from server during this operation). Read more about Device Awake here.

   NotificationEventReceiver.java

   public class NotificationEventReceiver extends WakefulBroadcastReceiver {
   
       private static final String ACTION_START_NOTIFICATION_SERVICE = "ACTION_START_NOTIFICATION_SERVICE";
       private static final String ACTION_DELETE_NOTIFICATION = "ACTION_DELETE_NOTIFICATION";
       private static final int NOTIFICATIONS_INTERVAL_IN_HOURS = 2;
   
       public static void setupAlarm(Context context) {
           AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
           PendingIntent alarmIntent = getStartPendingIntent(context);
           alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,
                   getTriggerAt(new Date()),
                   NOTIFICATIONS_INTERVAL_IN_HOURS * AlarmManager.INTERVAL_HOUR,
                   alarmIntent);
       }
   
       @Override
       public void onReceive(Context context, Intent intent) {
           String action = intent.getAction();
           Intent serviceIntent = null;
           if (ACTION_START_NOTIFICATION_SERVICE.equals(action)) {
               Log.i(getClass().getSimpleName(), "onReceive from alarm, starting notification service");
               serviceIntent = NotificationIntentService.createIntentStartNotificationService(context);
           } else if (ACTION_DELETE_NOTIFICATION.equals(action)) {
               Log.i(getClass().getSimpleName(), "onReceive delete notification action, starting notification service to handle delete");
               serviceIntent = NotificationIntentService.createIntentDeleteNotification(context);
           }
   
           if (serviceIntent != null) {
               startWakefulService(context, serviceIntent);
           }
       }
   
       private static long getTriggerAt(Date now) {
           Calendar calendar = Calendar.getInstance();
           calendar.setTime(now);
           //calendar.add(Calendar.HOUR, NOTIFICATIONS_INTERVAL_IN_HOURS);
           return calendar.getTimeInMillis();
       }
   
       private static PendingIntent getStartPendingIntent(Context context) {
           Intent intent = new Intent(context, NotificationEventReceiver.class);
           intent.setAction(ACTION_START_NOTIFICATION_SERVICE);
           return PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
       }
   
       public static PendingIntent getDeleteIntent(Context context) {
           Intent intent = new Intent(context, NotificationEventReceiver.class);
           intent.setAction(ACTION_DELETE_NOTIFICATION);
           return PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
       }
   }
   

3. Now let's create an IntentService to actually create notifications.

   There, we specify onHandleIntent() which is responses on NotificationEventReceiver's intent we passed in startWakefulService method.

   If it's Delete action - we can log it to our analytics, for example. If it's Start notification intent - then by using NotificationCompat.Builder we're composing new notification and showing it by NotificationManager.notify. While composing notification, we are also setting pending intents for click and remove actions. Fairly Easy.

   NotificationIntentService.java

   public class NotificationIntentService extends IntentService {
   
       private static final int NOTIFICATION_ID = 1;
       private static final String ACTION_START = "ACTION_START";
       private static final String ACTION_DELETE = "ACTION_DELETE";
   
       public NotificationIntentService() {
           super(NotificationIntentService.class.getSimpleName());
       }
   
       public static Intent createIntentStartNotificationService(Context context) {
           Intent intent = new Intent(context, NotificationIntentService.class);
           intent.setAction(ACTION_START);
           return intent;
       }
   
       public static Intent createIntentDeleteNotification(Context context) {
           Intent intent = new Intent(context, NotificationIntentService.class);
           intent.setAction(ACTION_DELETE);
           return intent;
       }
   
       @Override
       protected void onHandleIntent(Intent intent) {
           Log.d(getClass().getSimpleName(), "onHandleIntent, started handling a notification event");
           try {
               String action = intent.getAction();
               if (ACTION_START.equals(action)) {
                   processStartNotification();
               }
               if (ACTION_DELETE.equals(action)) {
                   processDeleteNotification(intent);
               }
           } finally {
               WakefulBroadcastReceiver.completeWakefulIntent(intent);
           }
       }
   
       private void processDeleteNotification(Intent intent) {
           // Log something?
       }
   
       private void processStartNotification() {
           // Do something. For example, fetch fresh data from backend to create a rich notification?
   
           final NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
           builder.setContentTitle("Scheduled Notification")
                   .setAutoCancel(true)
                   .setColor(getResources().getColor(R.color.colorAccent))
                   .setContentText("This notification has been triggered by Notification Service")
                   .setSmallIcon(R.drawable.notification_icon);
   
           PendingIntent pendingIntent = PendingIntent.getActivity(this,
                   NOTIFICATION_ID,
                   new Intent(this, NotificationActivity.class),
                   PendingIntent.FLAG_UPDATE_CURRENT);
           builder.setContentIntent(pendingIntent);
           builder.setDeleteIntent(NotificationEventReceiver.getDeleteIntent(this));
   
           final NotificationManager manager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
           manager.notify(NOTIFICATION_ID, builder.build());
       }
   }
   

4. Almost done. Now I also add broadcast receiver for BOOT_COMPLETED, TIMEZONE_CHANGED, and TIME_SET events to re-setup my AlarmManager, once device has been rebooted or timezone has changed (For example, user flown from USA to Europe and you don't want notification to pop up in the middle of the night, but was sticky to the local time :-) ).

   NotificationServiceStarterReceiver.java

   public final class NotificationServiceStarterReceiver extends BroadcastReceiver {
   
       @Override
       public void onReceive(Context context, Intent intent) {
           NotificationEventReceiver.setupAlarm(context);
       }
   }
   

5. We need to also register all our services, broadcast receivers in AndroidManifest:

   <?xml version="1.0" encoding="utf-8"?>
   <manifest xmlns:android="http://schemas.android.com/apk/res/android"
       package="klogi.com.notificationbyschedule">

       <uses-permission android:name="android.permission.WAKE_LOCK" />
   
       <application
           android:allowBackup="true"
           android:icon="@mipmap/ic_launcher"
           android:label="@string/app_name"
           android:supportsRtl="true"
           android:theme="@style/AppTheme">
           <activity android:name=".MainActivity">
               <intent-filter>
                   <action android:name="android.intent.action.MAIN" />
   
                   <category android:name="android.intent.category.LAUNCHER" />
               </intent-filter>
           </activity>
   
           <service
               android:name=".notifications.NotificationIntentService"
               android:enabled="true"
               android:exported="false" />
   
           <receiver android:name=".broadcast_receivers.NotificationEventReceiver" />
           <receiver android:name=".broadcast_receivers.NotificationServiceStarterReceiver">
               <intent-filter>
                   <action android:name="android.intent.action.BOOT_COMPLETED" />
                   <action android:name="android.intent.action.TIMEZONE_CHANGED" />
                   <action android:name="android.intent.action.TIME_SET" />
               </intent-filter>
           </receiver>
   
           <activity
               android:name=".NotificationActivity"
               android:label="@string/title_activity_notification"
               android:theme="@style/AppTheme.NoActionBar"/>
       </application>
   
   </manifest>
   

That's it!

The source code for this project you can find here. I hope, you will find this post helpful.

I got the same error in my microservice project.The property itself missed in my yml file.So I added property name and value that resolves my problem

You can use

Select to_date('08/15/2017 12:00:00 AM','MM/DD/YYYY HH:MI:SS AM') from dual;

If you are using it in an SP then your variable datatype should be Varchar2

and also in your ado.net code the datatype of your input parameter should be

OracleDbType.Varchar2

Basically I had to put a DateFrom and DateTo filter in my SP so I passed dates as String in it.

Note: This is one of the solution which worked for me, there could be more solutions to this problem.

If you don't have 'HIBERNATE_SEQUENCE' sequence created in database (if use oracle or any sequence based database), you shall get same type of error;

Ensure the sequence is present there;

If the value stored in PropertyLoader.RET_SECONDARY_V_ARRAY is not "V_ARRAY", then you are using different types; even if they are declared identically (e.g. both are table of number) this will not work.

You're hitting this data type compatibility restriction:

You can assign a collection to a collection variable only if they have the same data type. Having the same element type is not enough.

You're trying to call the procedure with a parameter that is a different type to the one it's expecting, which is what the error message is telling you.

You should always give an argument to your maven command. Normally this is one of the lifecycles. For example:

mvn package

Package will create jars, wars, ears etc.

For more phases and their meaning, see: http://maven.apache.org/guides/introduction/introduction-to-the-lifecycle.html

Create a dummy tag that is not going to rendered on the page but it will work as holder for ng-repeat:

<dummyTag ng-repeat="featureItem in item.features">{{featureItem.feature}}</br> </dummyTag>

From the update 2 and after narrowing down the problem scope, we can easily find that there is a brace missing at the end of the function addWord. The compiler will never explicitly identify such a syntax error. instead, it will assume that the missing function definition located in some other object file. The linker will complain about it and hence directly will be categorized under one of the broad the error phrases which is identifier is undefined. Reasonably, because with the current syntax the next function definition (in this case is ac_search) will be included under the addWord scope. Hence, it is not a global function anymore. And that is why compiler will not see this function outside addWord and will throw this error message stating that there is no such a function. A very good elaboration about the compiler and the linker can be found in this article

Nothing in the example says that the "classes implementing the same interface". MovieCatalog is a type and CustomerPreferenceDao is another type. Spring can easily tell them apart.

In Spring 2.x, wiring of beans mostly happened via bean IDs or names. This is still supported by Spring 3.x but often, you will have one instance of a bean with a certain type - most services are singletons. Creating names for those is tedious. So Spring started to support "autowire by type".

What the examples show is various ways that you can use to inject beans into fields, methods and constructors.

The XML already contains all the information that Spring needs since you have to specify the fully qualified class name in each bean. You need to be a bit careful with interfaces, though:

This autowiring will fail:

 @Autowired
 public void prepare( Interface1 bean1, Interface1 bean2 ) { ... }

Since Java doesn't keep the parameter names in the byte code, Spring can't distinguish between the two beans anymore. The fix is to use @Qualifier:

 @Autowired
 public void prepare( @Qualifier("bean1") Interface1 bean1,
     @Qualifier("bean2")  Interface1 bean2 ) { ... }

Your JSON string is malformed: the type of center is an array of invalid objects. Replace [ and ] with { and } in the JSON string around longitude and latitude so they will be objects:

[
    {
        "name" : "New York",
        "number" : "732921",
        "center" : {
                "latitude" : 38.895111, 
                "longitude" : -77.036667
            }
    },
    {
        "name" : "San Francisco",
        "number" : "298732",
        "center" : {
                "latitude" : 37.783333, 
                "longitude" : -122.416667
            }
    }
]

It is also possible to receive this error from a select component if the query fails in an unusual manner (eg: a sub-query returns multiple rows in an oracle oledb connection)

use app.set & app.get

Setting data

router.get(
  "/facebook/callback",
  passport.authenticate("facebook"),
  (req, res) => {
    req.app.set('user', res.req.user)
    return res.redirect("/sign");
  }
);

Getting data

router.get("/sign", (req, res) => {
  console.log('sign', req.app.get('user'))
});

As the error says, you need to make sure that your sql server is running and listening on port 1433. If server is running then you need to check whether there is some firewall rule rejecting the connection on port 1433.

Here are the commands that can be useful to troubleshoot:

1. Use netstat -a to check whether sql server is listening on the desired port
2. As gerrytan mentioned in answer, you can try to do the telnet on the host and port

Please add try catch also in your code so that you can be sure that there in no exception.

try {
    $hostname = "servername";
    $dbname = "dbname";
    $username = "username";
    $pw = "password";
    $pdo = new PDO ("mssql:host=$hostname;dbname=$dbname","$username","$pw");
  } catch (PDOException $e) {
    echo "Failed to get DB handle: " . $e->getMessage() . "\n";
    exit;
  }

Not sure, but what I think you're looking for is to create a java.util.Date from a String, then convert that java.util.Date to a java.sql.Date.

try this:

private static java.sql.Date getCurrentDate(String date) {

    java.util.Date today;
    java.sql.Date rv = null;
    try {

        SimpleDateFormat format = new SimpleDateFormat("dd-MM-yyyy");
        today = format.parse(date);
        rv = new java.sql.Date(today.getTime());
        System.out.println(rv.getTime());

    } catch (Exception e) {
        System.out.println("Exception: " + e.getMessage());
    } finally {
        return rv;
    }

}    

Will return a java.sql.Date object for setDate();

The function above will print out a long value:

1375934400000

Thou the above answer is widely accepted and well documented, I found some of the reason to post my answer here :-

    doNothing().when(InternalUtils.class); //This is the preferred way
                                           //to mock static void methods.
    InternalUtils.sendEmail(anyString(), anyString(), anyString(), anyString());

Here, I dont understand why we are calling InternalUtils.sendEmail ourself. I will explain in my code why we don't need to do that.

mockStatic(Internalutils.class);

So, we have mocked the class which is fine. Now, lets have a look how we need to verify the sendEmail(/..../) method.

@PrepareForTest({InternalService.InternalUtils.class})
@RunWith(PowerMockRunner.class)
public class InternalServiceTest {

    @Mock
    private InternalService.Order order;

    private InternalService internalService;

    @Before
    public void setup() {
        MockitoAnnotations.initMocks(this);
        internalService = new InternalService();
    }

    @Test
    public void processOrder() throws Exception {

        Mockito.when(order.isSuccessful()).thenReturn(true);
        PowerMockito.mockStatic(InternalService.InternalUtils.class);

        internalService.processOrder(order);

        PowerMockito.verifyStatic(times(1));
        InternalService.InternalUtils.sendEmail(anyString(), any(String[].class), anyString(), anyString());
    }

}

These two lines is where the magic is, First line tells the PowerMockito framework that it needs to verify the class it statically mocked. But which method it need to verify ?? Second line tells which method it needs to verify.

PowerMockito.verifyStatic(times(1));
InternalService.InternalUtils.sendEmail(anyString(), any(String[].class), anyString(), anyString());

This is code of my class, sendEmail api twice.

public class InternalService {

    public void processOrder(Order order) {
        if (order.isSuccessful()) {
            InternalUtils.sendEmail("", new String[1], "", "");
            InternalUtils.sendEmail("", new String[1], "", "");
        }
    }

    public static class InternalUtils{

        public static void sendEmail(String from, String[]  to, String msg, String body){

        }

    }

    public class Order{

        public boolean isSuccessful(){
            return true;
        }

    }

}

As it is calling twice you just need to change the verify(times(2))... that's all.

If you have a space in the name of the workbook you must use single quotes (') around the file name. I have also removed the full stop.

Application.Run "'Python solution macro.xlsm'!PreparetheTables"

1. Your UPDATE syntax is wrong
2. You probably meant to update a row not all of them so you have to use WHERE clause to target your specific row

Change

UPDATE `access_users`   
      (`contact_first_name`,`contact_surname`,`contact_email`,`telephone`) 
      VALUES (:firstname, :surname, :telephone, :email)

to

UPDATE `access_users`   
   SET `contact_first_name` = :firstname,
       `contact_surname` = :surname,
       `contact_email` = :email,
       `telephone` = :telephone 
 WHERE `user_id` = :user_id -- you probably have some sort of id 

new java.sql.Date(Calendar.getInstance().getTimeInMillis());

Sometimes the execution runs first time, and when we do maven clean install it doesn't generate after that. The issue was using true for skipMain and skip properties under maven-compiler-plugin of the main pom File. Remove them if they were introduced as a part of any issue or suggestion.

Problem in your SQL :

You can construct your sql like this :

$wpdb->prepare(
 "INSERT INTO `wp_submitted_form` 
   (`name`,`email`,`phone`,`country`,`course`,`message`,`datesent`) 
   values ('$name', '$email', '$phone', '$country', 
         '$course', '$message', '$datesent')"
 );

You can also use $wpdb->insert()

$wpdb->insert('table_name', input_array())

I'll add this in here as my problem had something todo with my virtualenv:

I hadn't activated my virtual environment and was trying to install my requirements, this ultimately led to my install failing and throwing this error message.

So make sure you activate your virtualenv!

@JulienD Best way is to break above process into two steps.

Step 1 : Lets say 'rawList' as your list that you want to add as parameters in prepared statement.

Create another list :

ArrayList<String> listWithQuotes = new ArrayList<String>();

for(String element : rawList){
    listWithQuotes.add("'"+element+"'");
}

Step 2 : Make 'listWithQuotes' comma separated.

String finalString = StringUtils.join(listWithQuotes.iterator(),",");

'finalString' will be string parameters with each element as single quoted and comma separated.

You should Build your app instead of debugging process. Just follow this:

Build -> Build Bundles/APK(s) -> Build APK(s)

For me it worked a simple sudo pip -I install <package>.

As man pip states, -I ignores installed packages, forcing reinstall instead.

Here's what I've been doing:

  public void displayError(final String errorText) {
    Runnable doDisplayError = new Runnable() {
        public void run() {
            Toast.makeText(getApplicationContext(), errorText, Toast.LENGTH_LONG).show();
        }
    };
    messageHandler.post(doDisplayError);
}

That should allow the method to be called from either thread.

Where messageHandler is declared in the activity as ..

Handler messageHandler = new Handler();

Your problem comes from the 32/64 bit version of your JDK/JRE... Your shared lib is searched for a 32 bit version.

Your default JDK is a 32 bit version. Try to install a 64 bit one by default and relaunch your `.sh file.

As mentioned in duscusion: WEB-INF is not really a part of class path. If you use a common template such as maven, use src/main/resources or src/test/resources to place the app-context.xml into. Then you can use 'classpath:'.

Place your config file into src/main/resources/app-context.xml and use code

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:app-context.xml")
public class PersonControllerTest {
...
}

or you can make yout test context with different configuration of beans.

Place your config file into src/test/resources/test-app-context.xml and use code

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:test-app-context.xml")
public class PersonControllerTest {
...
}

    int  pos  = 0;
    yourSeekBar.setMax(mPlayer.getDuration());

After You start Your MediaPlayer i.e mplayer.start()

Try this code

while(mPlayer!=null){
         try {
                Thread.sleep(1000);
                pos  = mPlayer.getCurrentPosition();
            }  catch (Exception e) {
                //show exception in LogCat
            }
            yourSeekBar.setProgress(pos);

   }

Before you added this code you have to create xml resource for SeekBar and use it in Your Activity class of ur onCreate() method.

Just go to Web.Config from Main folder, not the one in Views Folder:

configSections

section name="entityFramework" type="System.Data. .....,Version=" <strong>5</strong>.0.0.0"..

<..>

ADJUST THE VERSION OF EntityFramework you have installed, ex. like Version 6.0.0.0"

Right click on project - >BuildPath - >Configure BuildPath - >Libraries tab - >

Double click on JRE SYSTEM LIBRARY - >Then select alternate JRE

PDOStatement::fetch returns a row from the result set. The parameter PDO::FETCH_ASSOC tells PDO to return the result as an associative array.

The array keys will match your column names. If your table contains columns 'email' and 'password', the array will be structured like:

Array
(
    [email] => '[email protected]'
    [password] => 'yourpassword'
)

To read data from the 'email' column, do:

$user['email'];

and for 'password':

$user['password'];

Could be due to the TCP protocol turned off.

This video tutorial worked for me:

First, check that whatever you are returning via unicode is a String.

If it is not a string you can change it to a string like this (where self.id is an integer)

def __unicode__(self):
    return '%s' % self.id

following which, if it still doesn't work, restart your ./manage.py shell for the changes to take effect and try again. It should work.

Best Regards

You may use AddWithValue method like:

string connString = ConfigurationManager.ConnectionStrings["default"].ConnectionString;
MySqlConnection conn = new MySqlConnection(connString);
conn.Open();
MySqlCommand comm = conn.CreateCommand();
comm.CommandText = "INSERT INTO room(person,address) VALUES(@person, @address)";
comm.Parameters.AddWithValue("@person", "Myname");
comm.Parameters.AddWithValue("@address", "Myaddress");
comm.ExecuteNonQuery();
conn.Close();

OR

Try with ? instead of @, like:

string connString = ConfigurationManager.ConnectionStrings["default"].ConnectionString;
MySqlConnection conn = new MySqlConnection(connString);
conn.Open();
MySqlCommand comm = conn.CreateCommand();
comm.CommandText = "INSERT INTO room(person,address) VALUES(?person, ?address)";
comm.Parameters.Add("?person", "Myname");
comm.Parameters.Add("?address", "Myaddress");
comm.ExecuteNonQuery();
conn.Close();

Hope it helps...

Maybe I'm a little bit late :), but here is a nice and brief solution by chrisjhoughton, which allows to perform a callback function when the wait is over.

https://gist.github.com/chrisjhoughton/7890303

var waitForEl = function(selector, callback) {
  if (jQuery(selector).length) {
    callback();
  } else {
    setTimeout(function() {
      waitForEl(selector, callback);
    }, 100);
  }
};

waitForEl(selector, function() {
  // work the magic
});

If you need to pass parameters to a callback function, you can use it this way:

waitForEl("#" + elDomId, () => callbackFunction(param1, param2));

But be careful! This solution by default can fall into a trap of an infinite loop.

Several improvements of the topicstarter's suggestion are also provided in The GitHub thread.

Enjoy!

Creating a tableview using tableViewController .

The easiest way is to handle all of your database interactions in its own module that you export to your routes. If your route has no context of the database then SQL can't touch it anyway.

UICollectionView has changed in iOS 10 introducing some problems to solutions above.

Here is a good guide: https://littlebitesofcocoa.com/241-uicollectionview-cell-pre-fetching

Cells now stay around for a bit after going off-screen. Which means that sometimes we might not be able to get hold of a cell in didDeselectItemAt indexPath in order to adjust it. It can then show up on screen un-updated and un-recycled. prepareForReuse does not help this corner case.

The easiest solution is disabling the new scrolling by setting isPrefetchingEnabled to false. With this, managing the cell's display with cellForItemAt didSelect didDeselect works as it used to.

However, if you'd rather keep the new smooth scrolling behaviour it's better to use willDisplay :

func collectionView(_ collectionView: UICollectionView, willDisplay cell: UICollectionViewCell, forItemAt indexPath: IndexPath) {
    let customCell = cell as! CustomCell
    if customCell.isSelected {
        customCell.select()
    } else {
        customCell.unselect()
    }
}

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "CustomCell", for: indexPath) as! CustomCell
    //Don't even need to set selection-specific things here as recycled cells will also go through willDisplay
    return cell
}

func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
    let cell = collectionView.cellForItem(at: indexPath) as? CustomCell
    cell?.select()
}

func collectionView(_ collectionView: UICollectionView, didDeselectItemAt indexPath: IndexPath) {
    let cell = collectionView.cellForItem(at: indexPath) as? CustomCell
    cell?.unselect() // <----- this can be null here, and the cell can still come back on screen!
}

With the above you control the cell when it's selected, unselected on-screen, recycled, and just re-displayed.

For me, the problem was a ContextRefreshedEvent handler. I was doing some data initilization but at that point in the application the Authentication had not been set. It was a catch 22 since the system needed an authentication to authorize and it needed authorization to get the authentication details :). I ended up loosening the authorization from a class level to a method level.

If you are stuck with a legacy database where someone already placed JPA annotations on but did NOT define the relationships and you are now trying to define them for use in your code, then you might NOT be able to delete the customerId @Column since other code may directly reference it already. In that case, define the relationships as follows:

@ManyToOne(optional=false)
@JoinColumn(name="productId",referencedColumnName="id_product", insertable=false, updatable=false)
private Product product;

@ManyToOne(optional=false)
@JoinColumn(name="customerId",referencedColumnName="id_customer", insertable=false, updatable=false)
private Customer customer;

This allows you to access the relationships. However, to add/update to the relationships you will have to manipulate the foreign keys directly via their defined @Column values. It's not an ideal situation, but if you are handed this sort of situation, at least you can define the relationships so that you can use JPQL successfully.

Flexbox spec editor here.

This is an encouraged use of flexbox, but there are a few things you should tweak for best behavior.

• Don't use prefixes. Unprefixed flexbox is well-supported across most browsers. Always start with unprefixed, and only add prefixes if necessary to support it.

• Since your header and footer aren't meant to flex, they should both have flex: none; set on them. Right now you have a similar behavior due to some overlapping effects, but you shouldn't rely on that unless you want to accidentally confuse yourself later. (Default is flex:0 1 auto, so they start at their auto height and can shrink but not grow, but they're also overflow:visible by default, which triggers their default min-height:auto to prevent them from shrinking at all. If you ever set an overflow on them, the behavior of min-height:auto changes (switching to zero rather than min-content) and they'll suddenly get squished by the extra-tall <article> element.)

• You can simplify the <article> flex too - just set flex: 1; and you'll be good to go. Try to stick with the common values in https://drafts.csswg.org/css-flexbox/#flex-common unless you have a good reason to do something more complicated - they're easier to read and cover most of the behaviors you'll want to invoke.

The quirky syntax using conditions on the target (described by Mads) is the only supported way to perform conditional execution in core ANT.

ANT is not a programming language and when things get complicated I choose to embed a script within my build as follows:

<target name="prepare-copy" description="copy file based on condition">
    <groovy>
        if (properties["some.condition"] == "true") {
            ant.copy(file:"${properties["some.dir"]}/true", todir:".")
        }
    </groovy>
</target>

ANT supports several languages (See script task), my preference is Groovy because of it's terse syntax and because it plays so well with the build.

Apologies, David I am not a fan of ant-contrib.

As @TechSpellBound suggested remove the quotes around the ? signs. Then add a space character at the end of each row in your concatenated string. Otherwise the entire query will be sent as (using only part of it as an example) : .... WHERE bookings.booking_end < date ?OR bookings.booking_start > date ?GROUP BY ....

The ? and the OR needs to be seperated by a space character. Do it wherever needed in the query string.

Have a look at this

for outputing from mongo shell to file. There is no support for outputing csv from mongos shell. You would have to write the javascript yourself or use one of the many converters available. Google "convert json to csv" for example.

Just in case some other poor sod ends up here because they are having the same issue I was: if you have multiple data sources and this is happening with the non-primary data source, then the problem might be with that config. The data source, entity manager factory, and transaction factory all need to be correctly configured, but also -- and this is what tripped me up -- MAKE SURE TO TIE THEM ALL TOGETHER! @EnableJpaRepositories (configuration class annotation) must include entityManagerFactoryRef and transactionManagerRef to pick up all the configuration!

The example in this blog finally helped me see what I was missing, which (for quick reference) were the refs here:

@EnableJpaRepositories(
    entityManagerFactoryRef = "barEntityManagerFactory",
    transactionManagerRef = "barTransactionManager",
    basePackages = "com.foobar.bar")

Hope this helps save someone else from the struggle I've endured!

I had the same problem but was able to fix it by doing the following:

Right-click on the project -> Properties, then add the JAR (odjbc6 or 14) file in the deployment assembly.

img {
  filter: blur(var(--blur));
}

This setting useOldUTF8Behavior=true worked fine for me. It gave no incorrect string errors but it converted special characters like à into multiple characters and saved in the database.

To avoid such situations, I removed this property from the JDBC parameter and instead converted the datatype of my column to BLOB. This worked perfect.

Thanks to Marc B's help, here's what worked for me (note: Marc's rowCount() suggestion could work too, but I wasn't comfortable with the possibility of it not working on a different DB or if something changed in mine... also, his select count(*) suggestion would work too, but, I figured because I'd end up getting the data if it existed anyways, so I went this way)

$today = date('Y-m-d', strtotime('now'));

$sth = $db->prepare("SELECT id_email FROM db WHERE hardcopy = '1' AND hardcopy_date <= :today AND hardcopy_sent = '0' ORDER BY id_email ASC");

$sth->bindParam(':today',$today, PDO::PARAM_STR);

if(!$sth->execute()) {
    $db = null ;
    exit();
}

while ($row = $sth->fetch(PDO::FETCH_ASSOC)) {
    $this->id_email[] = $row['id_email'] ;
    echo $row['id_email'] ;
}
$db = null ;

if (count($this->id_email) > 0) {
    echo 'not empty';
    return true ;
}
echo 'empty';
return false ;

The problem was that you needed to add " ' ;" at the end.

If you are sending this back to asp.net and need the data in request.form[] then you'll need to set the content type to "application/x-www-form-urlencoded; charset=utf-8"

Secondly get rid of the Datatype, if your not expecting a return the POST will wait for about 4 minutes before failing. See here

The function ob_start() will turn output buffering on. While output buffering is active no output is sent from the script (other than headers), instead the output is stored in an internal buffer. So browser will not receive any output and the header will work.Also we should make sure that header() is used on the top of the code.

If you need to get the work done inside Pg:

If your application is a Java EE application running on Oracle WebLogic as the application server, a possible cause for this issue is the Statement Cache Size setting in WebLogic.

If the Statement Cache Size setting for a particular data source is about equal to, or greater than, the Oracle database maximum open cursor count setting, then all of the open cursors can be consumed by cached SQL statements that are held open by WebLogic, resulting in the ORA-01000 error.

To address this, reduce the Statement Cache Size setting for each WebLogic datasource that points to the Oracle database to be significantly less than the maximum cursor count setting on the database.

In the WebLogic 10 Admin Console, the Statement Cache Size setting for each data source can be found at Services (left nav) > Data Sources > (individual data source) > Connection Pool tab.

"No suitable driver" usually means that the JDBC URL you've supplied to connect has incorrect syntax or when the driver isn't loaded at all.

When the method getConnection is called, the DriverManager will attempt to locate a suitable driver from amongst those loaded at initialization and those loaded explicitly using the same classloader as the current applet or application.(using Class.forName())

For Example

import oracle.jdbc.driver.OracleDriver;

Class.forName("oracle.jdbc.driver.­OracleDriver");

Also check that you have ojdbc6.jar in your classpath. I would suggest to place .jar at physical location to JBoss "$JBOSS_HOME/server/default/lib/" directory of your project.

EDIT:

You have mentioned hibernate lately.

Check that your hibernate.cfg.xml file has connection properties something like this:

<property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
<property name="hibernate.connection.url">jdbc:oracle:thin:@localhost:1521:orcl</property> 
<property name="hibernate.connection.username">scott</property>
<property name="hibernate.connection.password">tiger</property>

For those using VPS / virtual hosting.

I was using a VPS, getting errors with MySQL not being able to write to /tmp, and everything looked correct. I had enough free space, enough free inodes, correct permissions. Turned out the problem was outside my VPS, it was the machine hosting the VPS that was full. I only had "virtual space" in my file system, but the machine in the background which hosted the VPS had no "physical space" left. I had to contact the VPS company any they fixed it.

If you think this might be your problem, you could test writing a larger file to /tmp (1GB):

dd if=/dev/zero of=/tmp/file.txt count=1024 bs=1048576 

I got a No space left on device error message, which was a giveaway that it was a disk/volume in the background that was full.

You must use the column names and then set the values to insert (both ? marks):

//insert 1st row            
String inserting = "INSERT INTO employee(emp_name ,emp_address) values(?,?)";
System.out.println("insert " + inserting);//
PreparedStatement ps = con.prepareStatement(inserting); 
ps.setString(1, "hans");
ps.setString(2, "germany");
ps.executeUpdate();

    Timestamp tsp = new Timestamp(System.currentTimeMillis());
   java.util.Date dateformat = new java.util.Date(tsp.getTime());

The following is my solution. Test it if it works for you:

The first plugin puts all dependencies in the target/classes/lib folder, and the second one includes the library folder in the final JAR file, and configures the Manifest.mf file.

But then you will need to add custom classloading code to load the JAR files.

Or, to avoid custom classloading, you can use "${project.build.directory}/lib, but in this case, you don't have dependencies inside the final JAR file, which defeats the purpose.

It's been two years since the question was asked. The problem of nested JAR files persists nevertheless. I hope it helps somebody.

Some how all the above solutions did not worked in hibernate 5.2.10.Final.

But setting the map to null as below worked for me:

playlist.setPlaylistadMaps(null);

The problem could also come because of a lack of SQL driver in your Tomcat installation directory.

I had to had mysql-connector-java-5.1.23-bin.jar in apache-tomcat-9.0.12/lib/ folder.

The value you have passed as the file descriptor is not valid. It is either negative or does not represent a currently open file or socket.

So you have either closed the socket before calling write() or you have corrupted the value of 'sockfd' somewhere in your code.

It would be useful to trace all calls to close(), and the value of 'sockfd' prior to the write() calls.

Your technique of only printing error messages in debug mode seems to me complete madness, and in any case calling another function between a system call and perror() is invalid, as it may disturb the value of errno. Indeed it may have done so in this case, and the real underlying error may be different.

edit: I guess it's now starting to be safe to use the native JSON.stringify() method, supported by most browsers (yes, even IE8+ if you're wondering).

As simple as:

JSON.stringify(yourData)

You should encode you data in JSON before sending it, you can't just send an object like this as POST data.

I recommand using the jQuery json plugin to do so. You can then use something like this in jQuery:

$.post(_saveDeviceUrl, {
    data : $.toJSON(postData)
}, function(response){
    //Process your response here
}
);

This error you are receiving :

SQLSTATE[HY093]: Invalid parameter number: parameter was not defined

is because the number of elements in $values & $matches is not the same or $matches contains more than 1 element.

If $matches contains more than 1 element, than the insert will fail, because there is only 1 column name referenced in the query(hash)

If $values & $matches do not contain the same number of elements then the insert will also fail, due to the query expecting x params but it is receiving y data $matches.

I believe you will also need to ensure the column hash has a unique index on it as well.

Try the code here:

<?php

/*** mysql hostname ***/
$hostname = 'localhost';

/*** mysql username ***/
$username = 'root';

/*** mysql password ***/
$password = '';

try {
    $dbh = new PDO("mysql:host=$hostname;dbname=test", $username, $password);
    /*** echo a message saying we have connected ***/
    echo 'Connected to database';
    }
catch(PDOException $e)
    {
    echo $e->getMessage();
    }


$matches = array('1');
$count = count($matches);
for($i = 0; $i < $count; ++$i) {
    $values[] = '?';
}

// INSERT INTO DATABASE
$sql = "INSERT INTO hashes (hash) VALUES (" . implode(', ', $values) . ") ON DUPLICATE KEY UPDATE hash='hash'";
$stmt = $dbh->prepare($sql);
$data = $stmt->execute($matches);

//Error reporting if something went wrong...
var_dump($dbh->errorInfo());

?>

You will need to adapt it a little.

Table structure I used is here:

CREATE TABLE IF NOT EXISTS `hashes` (
  `hashid` int(11) NOT NULL AUTO_INCREMENT,
  `hash` varchar(250) NOT NULL,
  PRIMARY KEY (`hashid`),
  UNIQUE KEY `hash1` (`hash`)
) ENGINE=InnoDB  DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;

Code was run on my XAMPP Server which is using PHP 5.3.8 with MySQL 5.5.16.

I hope this helps.

$st = $data->prepare("SELECT * FROM exampleWHERE example LIKE :search LIMIT 10"); 

final Handler handler = new Handler();
    handler.postDelayed(new Runnable() {
      @Override
      public void run() {
        //Do something after 100ms
        Toast.makeText(c, "check", Toast.LENGTH_SHORT).show();  
        handler.postDelayed(this, 2000);
      }
    }, 1500);

One of the reason may be if any one of table column have an underscore(_) in its name . That is considered as invalid characters by the JDBC . Rename the column by a ALTER Command and change in your code SQL , that will fix .

The JTable constructor accepts two arguments 2dimension Object Array for the data, and String Array for the column names.

eg:

import java.awt.BorderLayout;
import java.awt.Color;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTable;

public class Test6 extends JFrame {

    public Test6(){     
        this.setSize(300,300);
        this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        Mpanel m = new Mpanel();
        this.add(m,BorderLayout.CENTER);        
    }


    class Mpanel extends JPanel {       

        JTable mTable;
        private Object[][] cells = {{"Vivek",10.00},{"Vishal",20.00}};
        private String[] columnNames = { "Planet", "Radius" };
        JScrollPane mScroll;

        public Mpanel(){
            this.setSize(150,150);
            this.setComponent();
        }

        public void setComponent(){
            mTable = new JTable(cells,columnNames);
            mTable.setAutoCreateRowSorter(true);
            mScroll = new JScrollPane(mTable);

            this.add(mScroll);
        }
    }

    public static void main(String[] args){     
        new Test6().setVisible(true);
    }
}

This error is caused because your charset is wrong.

Set charset after open tag:

header('Content-Type: text/html; charset=utf-8');

And set charset utf8 in your database :

mysql_query("SET NAMES 'utf8'");

If you installed postresql on your server then just host: localhost to database.yml, I usually throw it in around where it says pool: 5. Otherwise if it's not localhost definitely tell that app where to find its database.

development:
  adapter: postgresql
  encoding: unicode
  database: kickrstack_development
  host: localhost
  pool: 5
  username: kickrstack
  password: secret

Make sure your user credentials are set correctly by creating a database and assigning ownership to your app's user to establish the connection. To create a new user in postgresql 9 run:

sudo -u postgres psql

set the postgresql user password if you haven't, it's just backslash password.

postgres=# \password

Create a new user and password and the user's new database:

postgres=# create user "guy_on_stackoverflow" with password 'keepitonthedl';
postgres=# create database "dcaclab_development" owner "guy_on_stackoverflow"; 

Now update your database.yml file after you've confirmed creating the database, user, password and set these privileges. Don't forget host: localhost.

You can do it the same way you do it with Mockito on real instances. For example you can chain stubs, the following line will make the first call do nothing, then second and future call to getResources will throw the exception :

// the stub of the static method
doNothing().doThrow(Exception.class).when(StaticResource.class);
StaticResource.getResource("string");

// the use of the mocked static code
StaticResource.getResource("string"); // do nothing
StaticResource.getResource("string"); // throw Exception

Thanks to a remark of Matt Lachman, note that if the default answer is not changed at mock creation time, the mock will do nothing by default. Hence writing the following code is equivalent to not writing it.

doNothing().doThrow(Exception.class).when(StaticResource.class);
StaticResource.getResource("string");

Though that being said, it can be interesting for colleagues that will read the test that you expect nothing for this particular code. Of course this can be adapted depending on how is perceived understandability of the test.

By the way, in my humble opinion you should avoid mocking static code if your crafting new code. At Mockito we think it's usually a hint to bad design, it might lead to poorly maintainable code. Though existing legacy code is yet another story.

Generally speaking if you need to mock private or static method, then this method does too much and should be externalized in an object that will be injected in the tested object.

Hope that helps.

The answer is simply that it makes no difference how the segue is triggered.

The prepareForSegue:sender: method is called in any case and this is where you pass your parameters across.

stmt.setDate(1, new java.sql.Date(cal.getTime().getTime()));

I am new in android programming and i had same error as this one. so i simply redefined the mp.createmediaPlayer = MediaPlayer.create(getApplicationContext(), Settings.System.DEFAULT_RINGTONE_URI). It may not the true way to do it but it worked fined for me:

try {
  mp = MediaPlayer.create(getApplicationContext(), Settings.System.DEFAULT_RINGTONE_URI);
} catch (Exception e) {
  e.printStackTrace();
}

mp.start();

The following is a test class that mocks private static final Logger named log in class LogUtil.

In addition to mocking the getLogger factory call, it is necessary to explicitly set the field using reflection, in @BeforeClass

public class LogUtilTest {

    private static Logger logger;

    private static MockedStatic<LoggerFactory> loggerFactoryMockedStatic;

    /**
     * Since {@link LogUtil#log} being a static final variable it is only initialized once at the class load time
     * So assertions are also performed against the same mock {@link LogUtilTest#logger}
     */
    @BeforeClass
    public static void beforeClass() {
        logger = mock(Logger.class);
        loggerFactoryMockedStatic = mockStatic(LoggerFactory.class);
        loggerFactoryMockedStatic.when(() -> LoggerFactory.getLogger(anyString())).thenReturn(logger);
        Whitebox.setInternalState(LogUtil.class, "log", logger);
    }

    @AfterClass
    public static void after() {
        loggerFactoryMockedStatic.close();
    }
} 

Take a look at Google Play Location Samples

Location Updates using a Foreground Service: Get updates about a device's location using a bound and started foreground service.

You need to set the error mode attribute PDO::ATTR_ERRMODE to PDO::ERRMODE_EXCEPTION.
And since you expect the exception to be thrown by the prepare() method you should disable the PDO::ATTR_EMULATE_PREPARES* feature. Otherwise the MySQL server doesn't "see" the statement until it's executed.

<?php
try {
    $pdo = new PDO('mysql:host=localhost;dbname=test;charset=utf8', 'localonly', 'localonly');
    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    $pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);


    $pdo->prepare('INSERT INTO DoesNotExist (x) VALUES (?)');
}
catch(Exception $e) {
    echo 'Exception -> ';
    var_dump($e->getMessage());
}

prints (in my case)

Exception -> string(91) "SQLSTATE[42S02]: Base table or view not found: 
1146 Table 'test.doesnotexist' doesn't exist"

see http://wezfurlong.org/blog/2006/apr/using-pdo-mysql/
EMULATE_PREPARES=true seems to be the default setting for the pdo_mysql driver right now. The query cache thing has been fixed/change since then and with the mysqlnd driver I hadn't problems with EMULATE_PREPARES=false (though I'm only a php hobbyist, don't take my word on it...)

*) and then there's PDO::MYSQL_ATTR_DIRECT_QUERY - I must admit that I don't understand the interaction of those two attributes (yet?), so I set them both, like

$pdo = new PDO('mysql:host=localhost;dbname=test;charset=utf8', 'localonly', 'localonly', array(
    PDO::ATTR_EMULATE_PREPARES=>false,
    PDO::MYSQL_ATTR_DIRECT_QUERY=>false,
    PDO::ATTR_ERRMODE=>PDO::ERRMODE_EXCEPTION
));

I realize that it's been a while since there has been any new activity on this question. But, as other posters have commented - get_result() is now only available in PHP by installing the MySQL native driver (mysqlnd), and in some cases, it may not be possible or desirable to install mysqlnd. So, I thought it would be helpful to post this answer with info on how get the functionality that get_result() offers - without using get_result().

get_result() is/was often combined with fetch_array() to loop through a result set and store the values from each row of the result set in a numerically-indexed or associative array. For example, the code below uses get_result() with fetch_array() to loop through a result set, storing the values from each row in the numerically-indexed $data[] array:

$c=1000;
$sql="select account_id, username from accounts where account_id<?";
$stmt = $mysqli->prepare($sql);                 
$stmt->bind_param('i', $c);                                             
$stmt->execute();
$result = $stmt->get_result();       
while($data = $result->fetch_array(MYSQLI_NUM)) {
   print $data[0] . ', ' . $data[1] . "<BR>\n"; 
}

However, if get_result() is not available (because mysqlnd is not installed), then this leads to the problem of how to store the values from each row of a result set in an array, without using get_result(). Or, how to migrate legacy code that uses get_result() to run without it (e.g. using bind_result() instead) - while impacting the rest of the code as little as possible.

It turns out that storing the values from each row in a numerically-indexed array is not so straight-forward using bind_result(). bind_result() expects a list of scalar variables (not an array). So, it takes some doing to make it store the values from each row of the result set in an array.

Of course, the code could easily be modified as follows:

$c=1000;
$sql="select account_id, username from accounts where account_id<?";
$stmt = $mysqli->prepare($sql);                 
$stmt->bind_param('i', $c);                                             
$stmt->execute();
$stmt->bind_result($data[0], $data[1]);
while ($stmt->fetch()) {
   print $data[0] . ', ' . $data[1] . "<BR>\n"; 
}

But, this requires us to explicitly list $data[0], $data[1], etc. individually in the call to bind_result(), which is not ideal. We want a solution that doesn't require us to have to explicitly list $data[0], $data[1], ... $data[N-1] (where N is the number of fields in the select statement) in the call to bind_results(). If we're migrating a legacy application that has a large number of queries, and each query may contain a different number of fields in the select clause, the migration will be very labor intensive and prone to error if we use a solution like the one above.

Ideally, we want a snippet of 'drop-in replacement' code - to replace just the line containing the get_result() function and the while() loop on the next line. The replacement code should have the same function as the code that it's replacing, without affecting any of the lines before, or any of the lines after - including the lines inside the while() loop. Ideally we want the replacement code to be as compact as possible, and we don't want to have to taylor the replacement code based on the number of fields in the select clause of the query.

Searching on the internet, I found a number of solutions that use bind_param() with call_user_func_array() (for example, Dynamically bind mysqli_stmt parameters and then bind result (PHP)), but most solutions that I found eventually lead to the results being stored in an associative array, not a numerically-indexed array, and many of these solutions were not as compact as I would like and/or were not suited as 'drop-in replacements'. However, from the examples that I found, I was able to cobble together this solution, which fits the bill:

$c=1000;
$sql="select account_id, username from accounts where account_id<?";
$stmt = $mysqli->prepare($sql);                 
$stmt->bind_param('i', $c);                                             
$stmt->execute();
$data=array();
for ($i=0;$i<$mysqli->field_count;$i++) { 
    $var = $i;
    $$var = null; 
    $data[$var] = &$$var; 
}
call_user_func_array(array($stmt,'bind_result'), $data);
while ($stmt->fetch()) {
   print $data[0] . ', ' . $data[1] . "<BR>\n"; 
}

Of course, the for() loop can be collapsed into one line to make it more compact.

I hope this helps anyone who is looking for a solution using bind_result() to store the values from each row in a numerically-indexed array and/or looking for a way to migrate legacy code using get_result(). Comments welcome.

The key phrase is need not be correctly escaped. That means that you don't to worry about people trying to throw in dashes, apostrophes, quotes, etc...

It is all handled for you.

String fname = "Sam\u0025";

PreparedStatement ps= conn.prepareStatement("SELECT * FROM Users WHERE User_FirstName LIKE ? ");

ps.setString(1, fname);

The next() moves the cursor froward one row from its current position in the resultset. so its evident that if(rs.next()) means that if the next row is not null (means if it exist), Go Ahead.

Now w.r.t your problem,

ResultSet rs = stmt.executeQuery(sql);  //This is wrong
                                  ^       

note that executeQuery(String) is used in case you use a sql-query as string.

Whereas when you use a PreparedStatement, use executeQuery() which executes the SQL query in this PreparedStatement object and returns the ResultSet object generated by the query.

Solution :

Use : ResultSet rs = stmt.executeQuery();

Yes, it is mainly to anchor your keywords, in particular the location of your page, so whenever URL loads the page with particular anchor name, then it will be pointed to that particular location.

For example, www.something.com/some_page/#computer if it is very lengthy page and you want to show exactly computer then you can anchor.

<p> adfadsf </p>
<p> adfadsf </p>
<p> adfadsf </p>
<a name="computer"></a><p> Computer topics </p>
<p> adfadsf </p>

Now the page will scroll and bring computer-related topics to the top.

Check if your connection string has "Trusted_Connection=true" added.

What about creating an additional wrapper class?

package com.naveen.research.sql;

import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;

public abstract class PreparedStatementWrapper implements AutoCloseable {

    protected PreparedStatement stat;

    public PreparedStatementWrapper(Connection con, String query, Object ... params) throws SQLException {
        this.stat = con.prepareStatement(query);
        this.prepareStatement(params);
    }

    protected abstract void prepareStatement(Object ... params) throws SQLException;

    public ResultSet executeQuery() throws SQLException {
        return this.stat.executeQuery();
    }

    public int executeUpdate() throws SQLException {
        return this.stat.executeUpdate();
    }

    @Override
    public void close() {
        try {
            this.stat.close();
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}

Then in the calling class you can implement prepareStatement method as:

try (Connection con = DriverManager.getConnection(JDBC_URL, prop);
    PreparedStatementWrapper stat = new PreparedStatementWrapper(con, query,
                new Object[] { 123L, "TEST" }) {
            @Override
            protected void prepareStatement(Object... params) throws SQLException {
                stat.setLong(1, Long.class.cast(params[0]));
                stat.setString(2, String.valueOf(params[1]));
            }
        };
        ResultSet rs = stat.executeQuery();) {
    while (rs.next())
        System.out.println(String.format("%s, %s", rs.getString(2), rs.getString(1)));
} catch (SQLException e) {
    e.printStackTrace();
}

Try:

String words[]=temp.split("\\.");

The method is:

String[] split(String regex) 

"." is a reserved char in regex

My solution is similar.

// In destination class: 
var AddressString:String = String()

// In segue:
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
   if (segue.identifier == "seguetobiddetailpagefromleadbidder")
    {
        let secondViewController = segue.destinationViewController as! BidDetailPage
        secondViewController.AddressString = pr.address as String
    }
}

Downgrading the JRE from 7 to 6 fixed this issue for me.

You might find this wiki article interesting : http://ajaxpatterns.org/On-Demand_Javascript

It explains how and when to use such technique.

This is due to using obsolete mysql-connection-java version, your MySQl is updated but not your MySQL jdbc Driver, you can update your connection jar from the official site Official MySQL Connector site. Good Luck.

I'd a similar problem in a legacy application, but de "--" was string parameter.

Ex.:

Dim cmd As New OracleCommand("INSERT INTO USER (name, address, photo) VALUES ('User1', '--', :photo)", oracleConnection)
Dim fs As IO.FileStream = New IO.FileStream("c:\img.jpg", IO.FileMode.Open)
Dim br As New IO.BinaryReader(fs)
cmd.Parameters.Add(New OracleParameter("photo", OracleDbType.Blob)).Value = br.ReadBytes(fs.Length)
cmd.ExecuteNonQuery() 'here throws ORA-01008

Changing address parameter value '--' to '00' or other thing, works.

Please find answer:

public class Customer {

    public static void main(String[] args) {
        Customer customer=new Customer();
        customer.business();
    }

    public void business(){
        System.out.println("Hi Harry");
    }
}

according to this snippet i use this code and it's working fine:

using System;
using System.IO;
using System.IO.Compression;
using System.Text;

namespace CompressString
{
    internal static class StringCompressor
    {

        /// <param name="text">The text.</param>
        /// <returns></returns>
        public static string CompressString(string text)
        {

In my case I was getting this error running my app in wildfly with the .ear deployed from eclipse. Because it was deployed from eclipse, the deployment folder did not contain an .ear file, but a folder representing it, and inside of it all the jars that would have been contained in the .ear file; like if the ear was unzipped.

So I had in on jar:

class MySuperClass {
  protected void mySuperMethod {}
}

And in another jar:

class MyExtendingClass extends MySuperClass {

  class MyChildrenClass {
    public void doSomething{
      mySuperMethod();
    }
  }
}

The solution for this was adding a new method to MyExtendingClass:

class MyExtendingClass extends MySuperClass {

  class MyChildrenClass {
    public void doSomething{
      mySuperMethod();
    }
  }

  @Override
  protected void mySuperMethod() {
    super.mySuperMethod();
  }
}

for those that just want to make a timezone aware datetime

import datetime
import pytz

datetime.datetime(2019, 12, 7, tzinfo=pytz.UTC)

you need to add jar file in your build path..

commons-dbcp-1.1-RC2.jar

or any version of that..!!!!

ADDED : also make sure you have commons-pool-1.1.jar too in your build path.

ADDED: sorry saw complete list of jar late... may be version clashes might be there.. better check out..!!! just an assumption.

It's worth noting that the SMTP module supports the context manager so there is no need to manually call quit(), this will guarantee it is always called even if there is an exception.

    with smtplib.SMTP_SSL('smtp.gmail.com', 465) as server:
        server.ehlo()
        server.login(user, password)
        server.sendmail(from, to, body)

Looks like we're coding the same application ;-)
Here is my current implementation. I'm still in the beta testing phase of my GPS uploader app, so there might be many possible improvements. but it seems to work pretty well so far.

/**
 * try to get the 'best' location selected from all providers
 */
private Location getBestLocation() {
    Location gpslocation = getLocationByProvider(LocationManager.GPS_PROVIDER);
    Location networkLocation =
            getLocationByProvider(LocationManager.NETWORK_PROVIDER);
    // if we have only one location available, the choice is easy
    if (gpslocation == null) {
        Log.d(TAG, "No GPS Location available.");
        return networkLocation;
    }
    if (networkLocation == null) {
        Log.d(TAG, "No Network Location available");
        return gpslocation;
    }
    // a locationupdate is considered 'old' if its older than the configured
    // update interval. this means, we didn't get a
    // update from this provider since the last check
    long old = System.currentTimeMillis() - getGPSCheckMilliSecsFromPrefs();
    boolean gpsIsOld = (gpslocation.getTime() < old);
    boolean networkIsOld = (networkLocation.getTime() < old);
    // gps is current and available, gps is better than network
    if (!gpsIsOld) {
        Log.d(TAG, "Returning current GPS Location");
        return gpslocation;
    }
    // gps is old, we can't trust it. use network location
    if (!networkIsOld) {
        Log.d(TAG, "GPS is old, Network is current, returning network");
        return networkLocation;
    }
    // both are old return the newer of those two
    if (gpslocation.getTime() > networkLocation.getTime()) {
        Log.d(TAG, "Both are old, returning gps(newer)");
        return gpslocation;
    } else {
        Log.d(TAG, "Both are old, returning network(newer)");
        return networkLocation;
    }
}

/**
 * get the last known location from a specific provider (network/gps)
 */
private Location getLocationByProvider(String provider) {
    Location location = null;
    if (!isProviderSupported(provider)) {
        return null;
    }
    LocationManager locationManager = (LocationManager) getApplicationContext()
            .getSystemService(Context.LOCATION_SERVICE);
    try {
        if (locationManager.isProviderEnabled(provider)) {
            location = locationManager.getLastKnownLocation(provider);
        }
    } catch (IllegalArgumentException e) {
        Log.d(TAG, "Cannot acces Provider " + provider);
    }
    return location;
}

Edit: here is the part that requests the periodic updates from the location providers:

public void startRecording() {
    gpsTimer.cancel();
    gpsTimer = new Timer();
    long checkInterval = getGPSCheckMilliSecsFromPrefs();
    long minDistance = getMinDistanceFromPrefs();
    // receive updates
    LocationManager locationManager = (LocationManager) getApplicationContext()
            .getSystemService(Context.LOCATION_SERVICE);
    for (String s : locationManager.getAllProviders()) {
        locationManager.requestLocationUpdates(s, checkInterval,
                minDistance, new LocationListener() {

                    @Override
                    public void onStatusChanged(String provider,
                            int status, Bundle extras) {}

                    @Override
                    public void onProviderEnabled(String provider) {}

                    @Override
                    public void onProviderDisabled(String provider) {}

                    @Override
                    public void onLocationChanged(Location location) {
                        // if this is a gps location, we can use it
                        if (location.getProvider().equals(
                                LocationManager.GPS_PROVIDER)) {
                            doLocationUpdate(location, true);
                        }
                    }
                });
        // //Toast.makeText(this, "GPS Service STARTED",
        // Toast.LENGTH_LONG).show();
        gps_recorder_running = true;
    }
    // start the gps receiver thread
    gpsTimer.scheduleAtFixedRate(new TimerTask() {

        @Override
        public void run() {
            Location location = getBestLocation();
            doLocationUpdate(location, false);
        }
    }, 0, checkInterval);
}

public void doLocationUpdate(Location l, boolean force) {
    long minDistance = getMinDistanceFromPrefs();
    Log.d(TAG, "update received:" + l);
    if (l == null) {
        Log.d(TAG, "Empty location");
        if (force)
            Toast.makeText(this, "Current location not available",
                    Toast.LENGTH_SHORT).show();
        return;
    }
    if (lastLocation != null) {
        float distance = l.distanceTo(lastLocation);
        Log.d(TAG, "Distance to last: " + distance);
        if (l.distanceTo(lastLocation) < minDistance && !force) {
            Log.d(TAG, "Position didn't change");
            return;
        }
        if (l.getAccuracy() >= lastLocation.getAccuracy()
                && l.distanceTo(lastLocation) < l.getAccuracy() && !force) {
            Log.d(TAG,
                    "Accuracy got worse and we are still "
                      + "within the accuracy range.. Not updating");
            return;
        }
        if (l.getTime() <= lastprovidertimestamp && !force) {
            Log.d(TAG, "Timestamp not never than last");
            return;
        }
    }
    // upload/store your location here
}

Things to consider:

• do not request GPS updates too often, it drains battery power. I currently use 30 min as default for my application.

• add a 'minimum distance to last known location' check. without this, your points will "jump around" when GPS is not available and the location is being triangulated from the cell towers. or you can check if the new location is outside of the accuracy value from the last known location.

Frequently we deal with other fellow java programmers work which create these Stored Procedure. and we do not want to mess around with it. but there is possibility you get the result set where these exec sample return 0 (almost Stored procedure call returning zero).

check this sample :

public void generateINOUT(String USER, int DPTID){

    try {


        conUrl = JdbcUrls + dbServers +";databaseName="+ dbSrcNames+";instance=MSSQLSERVER";

        con = DriverManager.getConnection(conUrl,dbUserNames,dbPasswords);
        //stat = con.createStatement();
        con.setAutoCommit(false); 
        Statement st = con.createStatement(); 

        st.executeUpdate("DECLARE @RC int\n" +
                "DECLARE @pUserID nvarchar(50)\n" +
                "DECLARE @pDepartmentID int\n" +
                "DECLARE @pStartDateTime datetime\n" +
                "DECLARE @pEndDateTime datetime\n" +
                "EXECUTE [AccessManager].[dbo].[SP_GenerateInOutDetailReportSimple] \n" +
                ""+USER +
                "," +DPTID+
                ",'"+STARTDATE +
                "','"+ENDDATE+"'");

        ResultSet rs = st.getGeneratedKeys();

        while (rs.next()){
              String userID = rs.getString("UserID");
              Timestamp timeIN = rs.getTimestamp("timeIN");
              Timestamp timeOUT = rs.getTimestamp ("timeOUT");
              int totTime = rs.getInt ("totalTime");
              int pivot = rs.getInt ("pivotvalue");

              timeINS = sdz.format(timeIN);
              userIN.add(timeINS);

              timeOUTS = sdz.format(timeOUT);
              userOUT.add(timeOUTS);

              System.out.println("User : "+userID+" |IN : "+timeIN+" |OUT : "+timeOUT+"| Total Time : "+totTime+" | PivotValue : "+pivot);
        }

        con.commit();

    }catch (Exception e) {
        e.printStackTrace();
        System.out.println(e);
        if (e.getCause() != null) {
        e.getCause().printStackTrace();}
    }  
}

check the query String I've done, that is your homework ;) so sorry answering this long, this is my first answer since I register few weeks ago to get answer.

If you are looking for PERFORMANCE, give where condition inside the db link query. Otherwise it fetch all data from the foreign table and apply the where condition.

INSERT INTO tblA (id,time) 
SELECT id, time FROM  dblink('dbname=dbname port=5432 host=10.10.90.190 user=postgresuser password=pass123', 
'select id, time from tblB  where time>'''||1000||'''')
AS t1(id integer, time integer)  

This should help you..:

import java.io.*;
import static java.lang.System.*;
/**
* Write a description of class InRead here.
* 
* @author (your name) 
* @version (a version number or a date)
*/
public class InRead
{
public InRead(String Recipe)
{
    find(Recipe);
}
public void find(String Name){
    String newRecipe= Name+".txt";
    try{
        FileReader fr= new FileReader(newRecipe);
        BufferedReader br= new BufferedReader(fr);

        String str;


    while ((str=br.readLine()) != null){
            out.println(str + "\n");
        }
        br.close();

    }catch (IOException e){
        out.println("File Not Found!");
    }
}

}

Option #1: Try invalidateOptionsMenu(). I don't know if this will force an immediate redraw of the action bar or not.

Option #2: See if getActionView() returns anything for the affected MenuItem. It is possible that showAsAction simply automatically creates action views for you. If so, you can presumably enable/disable that View.

I can't seem to find a way to get the currently set Menu to manipulate it except for in onPrepareOptionMenu.

You can hang onto the Menu object you were handed in onCreateOptionsMenu(). Quoting the docs:

You can safely hold on to menu (and any items created from it), making modifications to it as desired, until the next time onCreateOptionsMenu() is called.

if exists(select * from db1.table1 where sno=1 )
begin
select * from db1.table1 where sno=1 
end
else if (select * from db2.table1 where sno=1 )
begin
select * from db2.table1 where sno=1 
end
else
begin
print 'the record does not exits'
end

If you want just a single field, you could use fetchColumn instead of fetch - http://www.php.net/manual/en/pdostatement.fetchcolumn.php

PHP errors can be displayed by any of below methods:

ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

For more details:

Displaying PHP errors

I was getting the same error in my IBM Websphere with c3p0 jar files. I have Oracle 10g database. I simply added the oraclejdbc.jar files in the Application server JVM in IBM Classpath using Websphere Console and the error was resolved.

The oraclejdbc.jar should be set with your C3P0 jar files in your Server Class path whatever it be tomcat, glassfish of IBM.

So use the client-side loop to build a two-dimensional array of your arrays, and send the entire thing to PHP in one request.

Server-side, you'll need to have another loop which does its regular insert/update for each sub-array.

You create handler in background thread this way

private void createHandler() {
        Thread thread = new Thread() {
          public void run() {
               Looper.prepare();

               final Handler handler = new Handler();
               handler.postDelayed(new Runnable() {
                    @Override
                    public void run() {
                       // Do Work
                        handler.removeCallbacks(this);
                        Looper.myLooper().quit();
                   }
                }, 2000);

                Looper.loop();
            }
        };
        thread.start();
    }

query runs a standard SQL statement and requires you to properly escape all data to avoid SQL Injections and other issues.

execute runs a prepared statement which allows you to bind parameters to avoid the need to escape or quote the parameters. execute will also perform better if you are repeating a query multiple times. Example of prepared statements:

$sth = $dbh->prepare('SELECT name, colour, calories FROM fruit
    WHERE calories < :calories AND colour = :colour');
$sth->bindParam(':calories', $calories);
$sth->bindParam(':colour', $colour);
$sth->execute();
// $calories or $color do not need to be escaped or quoted since the
//    data is separated from the query

Best practice is to stick with prepared statements and execute for increased security.

See also: Are PDO prepared statements sufficient to prevent SQL injection?

The git diffs have an extra path segment prepended to the file paths. You can strip the this entry in the path by specifying -p1 with patch, like so:

patch -p1 < save.patch

from is a keyword in SQL. You may not used it as a column name without quoting it. In MySQL, things like column names are quoted using backticks, i.e. `from`.

Personally, I wouldn't bother; I'd just rename the column.

PS. as pointed out in the comments, to is another SQL keyword so it needs to be quoted, too. Conveniently, the folks at drupal.org maintain a list of reserved words in SQL.

From the javadocs:

When a Statement object is closed, its current ResultSet object, if one exists, is also closed.

However, the javadocs are not very clear on whether the Statement and ResultSet are closed when you close the underlying Connection. They simply state that closing a Connection:

Releases this Connection object's database and JDBC resources immediately instead of waiting for them to be automatically released.

In my opinion, always explicitly close ResultSets, Statements and Connections when you are finished with them as the implementation of close could vary between database drivers.

You can save yourself a lot of boiler-plate code by using methods such as closeQuietly in DBUtils from Apache.

It's been a while since your question, but ... Have you tried setting the Audio stream type?

mp.setAudioStreamType(AudioManager.STREAM_NOTIFICATION);

It must be done before prepare.

You can create a batch by PreparedStatement#addBatch() and execute it by PreparedStatement#executeBatch().

Here's a kickoff example:

public void save(List<Entity> entities) throws SQLException {
    try (
        Connection connection = database.getConnection();
        PreparedStatement statement = connection.prepareStatement(SQL_INSERT);
    ) {
        int i = 0;

        for (Entity entity : entities) {
            statement.setString(1, entity.getSomeProperty());
            // ...

            statement.addBatch();
            i++;

            if (i % 1000 == 0 || i == entities.size()) {
                statement.executeBatch(); // Execute every 1000 items.
            }
        }
    }
}

It's executed every 1000 items because some JDBC drivers and/or DBs may have a limitation on batch length.

See also:

• JDBC tutorial - Using PreparedStatement
• JDBC tutorial - Using Statement Objects for Batch Updates

Alternatively you can do:

Statement stmt = db.prepareStatement(query, Statement.RETURN_GENERATED_KEYS);
numero = stmt.executeUpdate();

ResultSet rs = stmt.getGeneratedKeys();
if (rs.next()){
    risultato=rs.getString(1);
}

But use Sean Bright's answer instead for your scenario.

You can either use the prepareStatement method taking an additional int parameter

PreparedStatement ps = con.prepareStatement(sql, Statement.RETURN_GENERATED_KEYS)

For some JDBC drivers (for example, Oracle) you have to explicitly list the column names or indices of the generated keys:

PreparedStatement ps = con.prepareStatement(sql, new String[]{"USER_ID"})

I tried every thing, but still I was unable to do that, I am using mysql, jpa with hibernate, I resolved my issue by assigning value of id 0 in constructor Following is my id declaration code

@Id
@Column(name="id",updatable=false,nullable=false)
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;

You should use datetime.datetime.strptime:

import datetime

dt = datetime.datetime.strptime(string_date, fmt)

fmt will need to be the appropriate format for your string. You'll find the reference on how to build your format here.

In express 4.0 they got it right :)

res.sendStatus(statusCode)
// Sets the response HTTP status code to statusCode and send its string representation as the response body.

res.sendStatus(200); // equivalent to res.status(200).send('OK')
res.sendStatus(403); // equivalent to res.status(403).send('Forbidden')
res.sendStatus(404); // equivalent to res.status(404).send('Not Found')
res.sendStatus(500); // equivalent to res.status(500).send('Internal Server Error')

//If an unsupported status code is specified, the HTTP status is still set to statusCode and the string version of the code is sent as the response body.

res.sendStatus(2000); // equivalent to res.status(2000).send('2000')

I feel that I need to extend my comment a bit...

About paradigm\style

That's probably the most notable aspect. FP became popular due to what you can get avoiding side-effects. I won't delve deep into what pros\cons you can get from this, since this is not related to the question.

However, I will say that the iteration using Iterable.forEach is inspired by FP and rather result of bringing more FP to Java (ironically, I'd say that there is no much use for forEach in pure FP, since it does nothing except introducing side-effects).

In the end I would say that it is rather a matter of taste\style\paradigm you are currently writing in.

About parallelism.

From performance point of view there is no promised notable benefits from using Iterable.forEach over foreach(...).

According to official docs on Iterable.forEach :

Performs the given action on the contents of the Iterable, in the order elements occur when iterating, until all elements have been processed or the action throws an exception.

... i.e. docs pretty much clear that there will be no implicit parallelism. Adding one would be LSP violation.

Now, there are "parallell collections" that are promised in Java 8, but to work with those you need to me more explicit and put some extra care to use them (see mschenk74's answer for example).

BTW: in this case Stream.forEach will be used, and it doesn't guarantee that actual work will be done in parallell (depends on underlying collection).

UPDATE: might be not that obvious and a little stretched at a glance but there is another facet of style and readability perspective.

First of all - plain old forloops are plain and old. Everybody already knows them.

Second, and more important - you probably want to use Iterable.forEach only with one-liner lambdas. If "body" gets heavier - they tend to be not-that readable. You have 2 options from here - use inner classes (yuck) or use plain old forloop. People often gets annoyed when they see the same things (iteratins over collections) being done various vays/styles in the same codebase, and this seems to be the case.

Again, this might or might not be an issue. Depends on people working on code.

<form action="Delegate_update.php" method="post">
  Name
  <input type="text" name= "Name" value= "<?php echo $row['Name']; ?> "size=10>
  Username
  <input type="text" name= "Username" value= "<?php echo $row['Username']; ?> "size=10>
  Password
  <input type="text" name= "Password" value= "<?php echo $row['Password']; ?>" size=17>
  <input type="submit" name= "submit" value="Update">
</form>

look into this

If you use Mozilla Firefox, It will work as expected without any issues;

P.S. Surprisingly, IntenetExplorer_Edge works absolutely fine!!!

For my specific situation I resolved the problem by using window.postMessage() and eliminating any user interaction. Note that this will only work if you can somehow execute js in the parent window. Either by having it include a js from your domain, or if you have direct access to the source.

In the iframe (domain-b) i check for the presence of a cookie and if it is not set will send a postMessage to the parent (domain-a). Eg;

if (navigator.userAgent.indexOf('Safari') != -1 && navigator.userAgent.indexOf('Chrome') == -1
    && document.cookie.indexOf("safari_cookie_fix") < 0) {
    window.parent.postMessage(JSON.stringify({ event: "safariCookieFix", data: {} }));
}

Then in the parent window (domain-a) listen for the event.

if (typeof window.addEventListener !== "undefined") {
    window.addEventListener("message", messageReceived, false);
}

function messageReceived (e) {
    var data;

    if (e.origin !== "http://www.domain-b.com") {
        return;
    }

    try {
        data = JSON.parse(e.data);
    }
    catch (err) {
        return;
    }

    if (typeof data !== "object" || typeof data.event !== "string" || typeof data.data === "undefined") {
        return;
    }

    if (data.event === "safariCookieFix") {
        window.location.href = e.origin + "/safari/cookiefix"; // Or whatever your url is
        return;
    }
}

Finally on your server (http://www.domain-b.com/safari/cookiefix) you set the cookie and redirect back to where the user came from. Below example is using ASP.NET MVC

public class SafariController : Controller
{
    [HttpGet]
    public ActionResult CookieFix()
    {
        Response.Cookies.Add(new HttpCookie("safari_cookie_fix", "1"));

        return Redirect(Request.UrlReferrer != null ? Request.UrlReferrer.OriginalString : "http://www.domain-a.com/");
    }

}

xs:boolean is predefined with regard to what kind of input it accepts. If you need something different, you have to define your own enumeration:

 <xs:simpleType name="my:boolean">
    <xs:restriction base="xs:string">
      <xs:enumeration value="True"/>
      <xs:enumeration value="False"/>
    </xs:restriction>
  </xs:simpleType>

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();

In this case it is just coding style.

Use of var is only necessary when dealing with anonymous types.
In other situations it's a matter of taste.

(I realise the question relates to C# however, if anyone reading needs to do the same thing with Java then the following may be useful)

It turns out that this can easily be done using the the "CellReference" class in Jakarta POI. Also, the conversion can be done both ways.

// Convert row and column numbers (0-based) to an Excel cell reference
CellReference numbers = new CellReference(3, 28);
System.out.println(numbers.formatAsString());

// Convert an Excel cell reference back into digits
CellReference reference = new CellReference("AC4");
System.out.println(reference.getRow() + ", " + reference.getCol());

As alternative you always can try a simpler workaround, using another icon, for example:

<button type="button" style="background:none;border:none">
    <span class="fa fa-reorder"></span>
</button>

ref: https://www.w3schools.com/icons/fontawesome_icons_webapp.asp

<button type="button" style="background:none;border:none">
    <span class="glyphicon glyphicon-align-justify"></span>
</button>

ref: https://www.w3schools.com/icons/bootstrap_icons_glyphicons.asp

So you gain total control over their color and size:

button span {
    /*overwriting*/
    color: white;
    font-size: 25px;
}

(the button's style applied is just for a quick test):

It is allowed (just do not use the object after that), but I wouldn't write such code on practice. I think that delete this should appear only in functions that called release or Release and looks like: void release() { ref--; if (ref<1) delete this; }.

The selected answer apparently does not work anymore in 2019 (at least for me).

I was trying to export a certificate using openssl (version 1.1.0) and the parameter -password doesn't work.

According to that link in the original answer (the same info is in man openssl), openssl has two parameter for passwords and they are -passin for the input parts and -passout for output files.

For the -export command, I used -passin for the password of my key file and -passout to create a new password for my P12 file.

So the complete command without any prompt was like below:

openssl pkcs12 -export -in /tmp/MyCert.crt -inkey /tmp/MyKey.key -out /tmp/MyP12.p12 -name alias -passin pass:keypassphrase -passout pass:certificatepassword

If you does not want a password, you can use pass: like below:

openssl pkcs12 -export -in /tmp/MyCert.crt -inkey /tmp/MyKey.key -out /tmp/MyP12.p12 -name alias -passin pass: -passout pass:

It will works fine with a key without password and the output certificate will be created without password too.

A shortcut you can add to your .bashrc etc, based on other answers here:

function perf {
  curl -o /dev/null -s -w "%{time_connect} + %{time_starttransfer} = %{time_total}\n" "$1"
}

Usage:

> perf stackoverflow.com
0.521 + 0.686 = 1.290

Use this function to regain the utf-8 characters

function decode_utf8(s) { 
  return decodeURIComponent(escape(s)); 
}

Example: var new_Str=decode_utf8(str);

This is the PHP ternary operator (also known as a conditional operator) - if first operand evaluates true, evaluate as second operand, else evaluate as third operand.

Think of it as an "if" statement you can use in expressions. Can be very useful in making concise assignments that depend on some condition, e.g.

$param = isset($_GET['param']) ? $_GET['param'] : 'default';

There's also a shorthand version of this (in PHP 5.3 onwards). You can leave out the middle operand. The operator will evaluate as the first operand if it true, and the third operand otherwise. For example:

$result = $x ?: 'default';

It is worth mentioning that the above code when using i.e. $_GET or $_POST variable will throw undefined index notice and to prevent that we need to use a longer version, with isset or a null coalescing operator which is introduced in PHP7:

$param = $_GET['param'] ?? 'default';

Upcoming pandas 0.13 version will allow to add rows through loc on non existing index data. However, be aware that under the hood, this creates a copy of the entire DataFrame so it is not an efficient operation.

Description is here and this new feature is called Setting With Enlargement.

simply add as many properties as you need to the data object.

                    type: "POST",
                    url: "popup.aspx/GetJewellerAssets",
                    contentType: "application/json; charset=utf-8",
                    data: {jewellerId: filter , foo: "bar", other: "otherValue"},
                    dataType: "json",
                    success: AjaxSucceeded,
                    error: AjaxFailed

You need to go through SimpleDateFormat.format in order to format the date as a string.

Here's an example that goes from String -> Date -> String.

SimpleDateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy");
Date date = dateFormat.parse("31/05/2011");

System.out.println(dateFormat.format(date));   // prints 31/05/2011
//                            ^^^^^^

The following code works fine with me:

brew install zbar
pip install pyqrcode
pip install pyzbar

For QR code image creation:

import pyqrcode
qr = pyqrcode.create("test1")
qr.png("test1.png", scale=6)

For QR code decoding:

from PIL import Image
from pyzbar.pyzbar import decode
data = decode(Image.open('test1.png'))
print(data)

that prints the result:

[Decoded(data=b'test1', type='QRCODE', rect=Rect(left=24, top=24, width=126, height=126), polygon=[Point(x=24, y=24), Point(x=24, y=150), Point(x=150, y=150), Point(x=150, y=24)])]

Although its an old question let me give my input on it as well.

1. abstract class: Inside abstract class we can declare instance variables, which are required to the child class

   Interface: Inside interface every variables is always public static and final we cannot declare instance variables

2. abstract class: Abstract class can talk about state of object

   Interface: Interface can never talk about state of object

3. abstract class: Inside Abstract class we can declare constructors

   Interface: Inside interface we cannot declare constructors as purpose of
   constructors is to initialize instance variables. So what is the need of constructor there if we cannot have instance variables in interfaces.

4. abstract class: Inside abstract class we can declare instance and static blocks

   Interface: Interfaces cannot have instance and static blocks.

5. abstract class: Abstract class cannot refer lambda expression

   Interfaces: Interfaces with single abstract method can refer lambda expression

6. abstract class: Inside abstract class we can override OBJECT CLASS methods

   Interfaces: We cannot override OBJECT CLASS methods inside interfaces.

I will end on the note that:

Default method concepts/static method concepts in interface came just to save implementation classes but not to provide meaningful useful implementation. Default methods/static methods are kind of dummy implementation, "if you want you can use them or you can override them (in case of default methods) in implementation class" Thus saving us from implementing new methods in implementation classes whenever new methods in interfaces are added. Therefore interfaces can never be equal to abstract classes.

Gradle Build Tools 2.2.0+ - Everything just works

This is the correct way to do it

In trying to avoid experimental and frankly fed up with the NDK and all its hackery I am happy that 2.2.x of the Gradle Build Tools came out and now it just works. The key is the externalNativeBuild and pointing ndkBuild path argument at an Android.mk or change ndkBuild to cmake and point the path argument at a CMakeLists.txt build script.

android {
    compileSdkVersion 19
    buildToolsVersion "25.0.2"

    defaultConfig {
        minSdkVersion 19
        targetSdkVersion 19

        ndk {
            abiFilters 'armeabi', 'armeabi-v7a', 'x86'
        }

        externalNativeBuild {
            cmake {
                cppFlags '-std=c++11'
                arguments '-DANDROID_TOOLCHAIN=clang',
                        '-DANDROID_PLATFORM=android-19',
                        '-DANDROID_STL=gnustl_static',
                        '-DANDROID_ARM_NEON=TRUE',
                        '-DANDROID_CPP_FEATURES=exceptions rtti'
            }
        }
    }

    externalNativeBuild {
        cmake {
             path 'src/main/jni/CMakeLists.txt'
        }
        //ndkBuild {
        //   path 'src/main/jni/Android.mk'
        //}
    }
}

For much more detail check Google's page on adding native code.

After this is setup correctly you can ./gradlew installDebug and off you go. You will also need to be aware that the NDK is moving to clang since gcc is now deprecated in the Android NDK.

I've never used it but Trilead, a free ISAPI filter which enables .htaccess based control, looks like what you want.

Static properties are usually placed on the (global) constructor for the object, whereas the "interface" keyword applies to instances of the object.

The previous answer given is of course correct if you are writing the class in TypeScript. It may help others to know that if you are describing an object that is already implemented elsewhere, then the global constructor including static properties can be declared like this:

declare var myInterface : {
  new(): Interface;
  Name:string;
}

I had the same problem. I had to embed a navigation controller and present the controller through it. Below is the sample code.

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.

    UIImagePickerController *cameraView = [[UIImagePickerController alloc]init];
    [cameraView setSourceType:UIImagePickerControllerSourceTypeCamera];
    [cameraView setShowsCameraControls:NO];

    UIView *cameraOverlay = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 768, 1024)];
    UIImageView *imageView = [[UIImageView alloc]initWithImage:[UIImage imageNamed:@"someImage"]];
    [imageView setFrame:CGRectMake(0, 0, 768, 1024)];
    [cameraOverlay addSubview:imageView];

    [cameraView setCameraOverlayView:imageView];

    [self.navigationController presentViewController:cameraView animated:NO completion:nil];
//    [self presentViewController:cameraView animated:NO completion:nil]; //this will cause view is not in the window hierarchy error

}

The easisest way to get a posted json string, for example, is to read the contents of 'php://input' and then decode it. For example i had a simple Zend route:

'save-json' => array(
'type' => 'Zend\Mvc\Router\Http\Segment',
            'options' => array(
                'route'    => '/save-json/',
                'defaults' => array(
                    'controller' => 'CDB\Controller\Index',
                    'action'     => 'save-json',
                ),
            ),
        ),

and i wanted to post data to it using Angular's $http.post. The post was fine but the retrive method in Zend

$this->params()->fromPost('paramname'); 

didn't get anything in this case. So my solution was, after trying all kinds of methods like $_POST and the other methods stated above, to read from 'php://':

$content = file_get_contents('php://input');
print_r(json_decode($content));

I got my json array in the end. Hope this helps.

Projections and Selections are two unary operations in Relational Algebra and has practical applications in RDBMS (relational database management systems).

In practical sense, yes Projection means selecting specific columns (attributes) from a table and Selection means filtering rows (tuples). Also, for a conventional table, Projection and Selection can be termed as vertical and horizontal slicing or filtering.

Wikipedia provides more formal definitions of these with examples and they can be good for further reading on relational algebra:

• Projection: https://en.wikipedia.org/wiki/Projection_(relational_algebra)
• Selection: https://en.wikipedia.org/wiki/Selection_(relational_algebra)

1. You can use Microsoft.Extensions.Configuration API with any .NET Core app, not only with ASP.NET Core app. Look into sample provided in the link, that shows how to read configs in the console app.

2. In most cases, the JSON source (read as .json file) is the most suitable config source.

   Note: don't be confused when someone says that config file should be appsettings.json. You can use any file name, that is suitable for you and file location may be different - there are no specific rules.

   But, as the real world is complicated, there are a lot of different configuration providers:

   • File formats (INI, JSON, and XML)
   • Command-line arguments
   • Environment variables

   and so on. You even could use/write a custom provider.

3. Actually, app.config configuration file was an XML file. So you can read settings from it using XML configuration provider (source on github, nuget link). But keep in mind, it will be used only as a configuration source - any logic how your app behaves should be implemented by you. Configuration Provider will not change 'settings' and set policies for your apps, but only read data from the file.

Fowloing code remove newline from both side of string:

select ltrim(rtrim('asbda'||CHR(10)||CHR(13) ,''||CHR(10)||CHR(13)),''||CHR(10)||CHR(13))  from dual

but in most cases this one is just enought :

select rtrim('asbda'||CHR(10)||CHR(13) ,''||CHR(10)||CHR(13)))  from dual

Use this to make the cell look like it is disabled and non-selectable:

cell.selectionStyle = UITableViewCellSelectionStyleNone;

Important: note that this is only a styling property, and does not actually disable the cell. In order to do that, you have to check for selectionStylein your didSelectRowAtIndexPath: delegate implementation:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    if(cell.selectionStyle == UITableViewCellSelectionStyleNone) {
        return;
    }

    // do your cell selection handling here
}

Quick and dirty, utilizing a simple flag:

var bindingsApplied = false;

var ViewModel = function() {
    // ...

    this.permissionChanged = function() {
        // ignore, if flag not set
        if (!flag) return;

        // ...
    };
};

ko.applyBindings(new ViewModel());
bindingsApplied = true; // done with the initial population, set flag to true

If this doesn't work, try wrapping the last line in a setTimeout() - events are async, so maybe the last one is still pending when applyBindings() already returned.

As your project is a console project you can pass the path to the text files that you want to read via the string[] args

static void Main(string[] args)
{
}

Within Main you can check if arguments are passed

if (args.Length == 0){ System.Console.WriteLine("Please enter a parameter");}

Extract an argument

string fileToRead = args[0];

Nearly all languages support the concept of argument passing and follow similar patterns to C#.

In my Case for android studio project. I have to enable Places API as well to get suggestions

This works for me.

The syntax is wrong in this clause (and similar ones)

    CASE lkey WHEN lkey > 5 THEN
        lkey + 2
    ELSE
        lkey
    END

It's either

    CASE WHEN [condition] THEN [expression] ELSE [expression] END

or

    CASE [expression] WHEN [value] THEN [expression] ELSE [expression] END

So in your case it would read:

    CASE WHEN lkey > 5 THEN
        lkey + 2
    ELSE
        lkey
    END

Check out the documentation (The CASE expression):

http://www.sqlite.org/lang_expr.html

it sometimes occurs when we use a custom adapter in any activity of fragment . and we return null object i.e null view so the activity gets confused which view to load , so that is why this exception occurs

shows the position where to change the view

Yes. You know that you can put any Object into the Object parameter of most JOptionPane.showXXX methods, and often that Object happens to be a JPanel.

In your situation, perhaps you could use a JPanel that has several JTextFields in it:

import javax.swing.*;

public class JOptionPaneMultiInput {
   public static void main(String[] args) {
      JTextField xField = new JTextField(5);
      JTextField yField = new JTextField(5);

      JPanel myPanel = new JPanel();
      myPanel.add(new JLabel("x:"));
      myPanel.add(xField);
      myPanel.add(Box.createHorizontalStrut(15)); // a spacer
      myPanel.add(new JLabel("y:"));
      myPanel.add(yField);

      int result = JOptionPane.showConfirmDialog(null, myPanel, 
               "Please Enter X and Y Values", JOptionPane.OK_CANCEL_OPTION);
      if (result == JOptionPane.OK_OPTION) {
         System.out.println("x value: " + xField.getText());
         System.out.println("y value: " + yField.getText());
      }
   }
}

One option to try is to put the image in the drawable-nodpi folder and set background of a layout to the drawable resource id.

This definitely works with scaling down, I haven't tested with scaling up though.

You can use React.cloneElement, it's better to know how it works before you start using it in your application. It's introduced in React v0.13, read on for more information, so something along with this work for you:

<div>{React.cloneElement(this.props.children, {...this.props})}</div>

So bring the lines from React documentation for you to understand how it's all working and how you can make use of them:

In React v0.13 RC2 we will introduce a new API, similar to React.addons.cloneWithProps, with this signature:

React.cloneElement(element, props, ...children);

Unlike cloneWithProps, this new function does not have any magic built-in behavior for merging style and className for the same reason we don't have that feature from transferPropsTo. Nobody is sure what exactly the complete list of magic things are, which makes it difficult to reason about the code and difficult to reuse when style has a different signature (e.g. in the upcoming React Native).

React.cloneElement is almost equivalent to:

<element.type {...element.props} {...props}>{children}</element.type>

However, unlike JSX and cloneWithProps, it also preserves refs. This means that if you get a child with a ref on it, you won't accidentally steal it from your ancestor. You will get the same ref attached to your new element.

One common pattern is to map over your children and add a new prop. There were many issues reported about cloneWithProps losing the ref, making it harder to reason about your code. Now following the same pattern with cloneElement will work as expected. For example:

var newChildren = React.Children.map(this.props.children, function(child) {
  return React.cloneElement(child, { foo: true })
});

Note: React.cloneElement(child, { ref: 'newRef' }) DOES override the ref so it is still not possible for two parents to have a ref to the same child, unless you use callback-refs.

This was a critical feature to get into React 0.13 since props are now immutable. The upgrade path is often to clone the element, but by doing so you might lose the ref. Therefore, we needed a nicer upgrade path here. As we were upgrading callsites at Facebook we realized that we needed this method. We got the same feedback from the community. Therefore we decided to make another RC before the final release to make sure we get this in.

We plan to eventually deprecate React.addons.cloneWithProps. We're not doing it yet, but this is a good opportunity to start thinking about your own uses and consider using React.cloneElement instead. We'll be sure to ship a release with deprecation notices before we actually remove it so no immediate action is necessary.

This is a modern Promise version of the previous one, using a Promise.all approach to resolve all promises when all files have been read:

/**
 * Promise all
 * @author Loreto Parisi (loretoparisi at gmail dot com)
 */
function promiseAllP(items, block) {
    var promises = [];
    items.forEach(function(item,index) {
        promises.push( function(item,i) {
            return new Promise(function(resolve, reject) {
                return block.apply(this,[item,index,resolve,reject]);
            });
        }(item,index))
    });
    return Promise.all(promises);
} //promiseAll

/**
 * read files
 * @param dirname string
 * @return Promise
 * @author Loreto Parisi (loretoparisi at gmail dot com)
 * @see http://stackoverflow.com/questions/10049557/reading-all-files-in-a-directory-store-them-in-objects-and-send-the-object
 */
function readFiles(dirname) {
    return new Promise((resolve, reject) => {
        fs.readdir(dirname, function(err, filenames) {
            if (err) return reject(err);
            promiseAllP(filenames,
            (filename,index,resolve,reject) =>  {
                fs.readFile(path.resolve(dirname, filename), 'utf-8', function(err, content) {
                    if (err) return reject(err);
                    return resolve({filename: filename, contents: content});
                });
            })
            .then(results => {
                return resolve(results);
            })
            .catch(error => {
                return reject(error);
            });
        });
  });
}

How to Use It:

Just as simple as doing:

readFiles( EMAIL_ROOT + '/' + folder)
.then(files => {
    console.log( "loaded ", files.length );
    files.forEach( (item, index) => {
        console.log( "item",index, "size ", item.contents.length);
    });
})
.catch( error => {
    console.log( error );
});

Supposed that you have another list of folders you can as well iterate over this list, since the internal promise.all will resolve each of then asynchronously:

var folders=['spam','ham'];
folders.forEach( folder => {
    readFiles( EMAIL_ROOT + '/' + folder)
    .then(files => {
        console.log( "loaded ", files.length );
        files.forEach( (item, index) => {
            console.log( "item",index, "size ", item.contents.length);
        });
    })
    .catch( error => {
        console.log( error );
    });
});

How it Works

The promiseAll does the magic. It takes a function block of signature function(item,index,resolve,reject), where item is the current item in the array, index its position in the array, and resolve and reject the Promise callback functions. Each promise will be pushed in a array at the current index and with the current item as arguments through a anonymous function call:

promises.push( function(item,i) {
        return new Promise(function(resolve, reject) {
            return block.apply(this,[item,index,resolve,reject]);
        });
    }(item,index))

Then all promises will be resolved:

return Promise.all(promises);

$('.submit').filter(':checked').each(function() {
    //This is same as 'continue'
    if(something){
        return true;
    }
    //This is same as 'break'
    if(something){
        return false;
    }
});

I will give a practical example in scraping web data using python, a lot of the times you will get keys with no values, in those cases you will get errors if you use dictionary['key'], whereas dictionary.get('key', 'return_otherwise') has no problems.

Similarly, I would use ''.join(list) as opposed to list[0] if you try to capture a single value from a list.

hope it helps.

[Edit] Here is a practical example:

Say, you are calling an API, which returns a JOSN file you need to parse. The first JSON looks like following:

{"bids":{"id":16210506,"submitdate":"2011-10-16 15:53:25","submitdate_f":"10\/16\/2011 at 21:53 CEST","submitdate_f2":"p\u0159ed 2 lety","submitdate_ts":1318794805,"users_id":"2674360","project_id":"1250499"}}

The second JOSN is like this:

{"bids":{"id":16210506,"submitdate":"2011-10-16 15:53:25","submitdate_f":"10\/16\/2011 at 21:53 CEST","submitdate_f2":"p\u0159ed 2 lety","users_id":"2674360","project_id":"1250499"}}

Note that the second JSON is missing the "submitdate_ts" key, which is pretty normal in any data structure.

So when you try to access the value of that key in a loop, can you call it with the following:

for item in API_call:
    submitdate_ts = item["bids"]["submitdate_ts"]

You could, but it will give you a traceback error for the second JSON line, because the key simply doesn't exist.

The appropriate way of coding this, could be the following:

for item in API_call:
    submitdate_ts = item.get("bids", {'x': None}).get("submitdate_ts")

{'x': None} is there to avoid the second level getting an error. Of course you can build in more fault tolerance into the code if you are doing scraping. Like first specifying a if condition

Just for educational purposes you could also do it with any of the following ways:

1.

If you want to get the file names only without the rest of the commit message you can use:

git log --name-only --pretty=format: <branch name>

This can then be extended to use the various options that contain the file name:

git log --name-status --pretty=format: <branch name>

git log --stat --pretty=format: <branch name>

One thing to note when using this method is that there are some blank lines in the output that will have to be ignored. Using this can be useful if you'd like to see the files that have been changed on a local branch, but is not yet pushed to a remote branch and there is no guarantee the latest from the remote has already been pulled in. For example:

git log --name-only --pretty=format: my_local_branch --not origin/master

Would show all the files that have been changed on the local branch, but not yet merged to the master branch on the remote.

Important: Please consider upgrading to MySQL 8+ and use the defined and documented ROW_NUMBER() function, and ditch old hacks tied to a feature limited ancient version of MySQL

Now here's one of those hacks:

The answers here that use in-query variables mostly/all seem to ignore the fact that the documentation says (paraphrase):

Don't rely on items in the SELECT list being evaluated in order from top to bottom. Don't assign variables in one SELECT item and use them in another one

As such, there's a risk they will churn out the wrong answer, because they typically do a

select
  (row number variable that uses partition variable),
  (assign partition variable)

If these are ever evaluated bottom up, the row number will stop working (no partitions)

So we need to use something with a guaranteed order of execution. Enter CASE WHEN:

SELECT
  t.*, 
  @r := CASE 
    WHEN col = @prevcol THEN @r + 1 
    WHEN (@prevcol := col) = null THEN null
    ELSE 1 END AS rn
FROM
  t, 
  (SELECT @r := 0, @prevcol := null) x
ORDER BY col

As outline ld, order of assignment of prevcol is important - prevcol has to be compared to the current row's value before we assign it a value from the current row (otherwise it would be the current rows col value, not the previous row's col value).

Here's how this fits together:

• The first WHEN is evaluated. If this row's col is the same as the previous row's col then @r is incremented and returned from the CASE. This return led values is stored in @r. It's a feature of MySQL that assignment returns the new value of what is assigned into @r into the result rows.

• For the first row on the result set, @prevcol is null (it is initialised to null in the subquery) so this predicate is false. This first predicate also returns false every time col changes (current row is different to previous row). This causes the second WHEN to be evaluated.

• The second WHEN predicate is always false, and it exists purely to assign a new value to @prevcol. Because this row's col is different to the previous row's col (we know this because if it were the same, the first WHEN would have been used), we have to assign the new value to keep it for testing next time. Because the assignment is made and then the result of the assignment is compared with null, and anything equated with null is false, this predicate is always false. But at least evaluating it did its job of keeping the value of col from this row, so it can be evaluated against the next row's col value

• Because the second WHEN is false, it means in situations where the column we are partitioning by (col) has changed, it is the ELSE that gives a new value for @r, restarting the numbering from 1

We this get to a situation where this:

SELECT
  t.*, 
  ROW_NUMBER() OVER(PARTITION BY pcol1, pcol2, ... pcolX ORDER BY ocol1, ocol2, ... ocolX) rn
FROM
  t

Has the general form:

SELECT
  t.*, 
  @r := CASE 
    WHEN col1 = @pcol1 AND col2 = @pcol2 AND ... AND colX = @pcolX THEN @r + 1 
    WHEN (@pcol1 := pcol1) = null OR (@pcol2 := col2) = null OR ... OR (@pcolX := colX) = null THEN null
    ELSE 1 
  END AS rn
FROM
  t, 
  (SELECT @r := 0, @pcol1 := null, @pcol2 := null, ..., @pcolX := null) x
ORDER BY pcol1, pcol2, ..., pcolX, ocol1, ocol2, ..., ocolX

Footnotes:

• The p in pcol means "partition", the o in ocol means "order" - in the general form I dropped the "prev" from the variable name to reduce visual clutter

• The brackets around (@pcolX := colX) = null are important. Without them you'll assign null to @pcolX and things stop working

• It's a compromise that the result set has to be ordered by the partition columns too, for the previous column compare to work out. You can't thus have your rownumber ordered according to one column but your result set ordered to another You might be able to resolve this with subqueries but I believe the docs also state that subquery ordering may be ignored unless LIMIT is used and this could impact performance

• I haven't delved into it beyond testing that the method works, but if there is a risk that the predicates in the second WHEN will be optimised away (anything compared to null is null/false so why bother running the assignment) and not executed, it also stops. This doesn't seem to happen in my experience but I'll gladly accept comments and propose solution if it could reasonably occur

• It may be wise to cast the nulls that create @pcolX to the actual types of your columns, in the subquery that creates the @pcolX variables, viz: select @pcol1 := CAST(null as INT), @pcol2 := CAST(null as DATE)

You're getting the toString() value returned by the Scanner object itself which is not what you want and not how you use a Scanner object. What you want instead is the data obtained by the Scanner object. For example,

Scanner input = new Scanner(System.in);
String data = input.nextLine();
System.out.println(data);

Please read the tutorial on how to use it as it will explain all.

Edit
Please look here: Scanner tutorial

Also have a look at the Scanner API which will explain some of the finer points of Scanner's methods and properties.

You can use Lookback. It records your screen, face, voice and all gestures, and uploads them to your account on the web.

Similar to Howard's answer but a bit more efficient:

def my_func(low, up, leng):
    step = ((up-low) * 1.0 / leng)
    return [low+i*step for i in xrange(leng)]

TLDR: Use map (returning undefined when needed) and then filter.

First, I believe that a map + filter function is useful since you don't want to repeat a computation in both. Swift originally called this function flatMap but then renamed it to compactMap.

For example, if we don't have a compactMap function, we might end up with computation defined twice:

  let array = [1, 2, 3, 4, 5, 6, 7, 8];
  let mapped = array
  .filter(x => {
    let computation = x / 2 + 1;
    let isIncluded = computation % 2 === 0;
    return isIncluded;
  })
  .map(x => {
    let computation = x / 2 + 1;
    return `${x} is included because ${computation} is even`
  })

  // Output: [2 is included because 2 is even, 6 is included because 4 is even]

Thus compactMap would be useful to reduce duplicate code.

A really simple way to do something similar to compactMap is to:

1. Map on real values or undefined.
2. Filter out all the undefined values.

This of course relies on you never needing to return undefined values as part of your original map function.

Example:

  let array = [1, 2, 3, 4, 5, 6, 7, 8];
  let mapped = array
  .map(x => {
    let computation = x / 2 + 1;
    let isIncluded = computation % 2 === 0;
    if (isIncluded) {
      return `${x} is included because ${computation} is even`
    } else {
      return undefined
    }
  })
  .filter(x => typeof x !== "undefined")

int numberOfRecords = DTb.Rows.Count;
int numberOfColumns = DTb.Columns.Count;

"When programming with C# you don’t usually need to worry about the underlying target platform. There are however a few cases when the Application and OS architecture can affect program logic, change functionality and cause unexpected exceptions."

"It is common misconception that selecting a specific target will result in the compiler generating platform specific code. This is not the case and instead it simply sets a flag in the assembly’s CLR header. This information can be easily extracted, and modified, using Microsoft’s CoreFlags tool"

I suspect you're only reporting the last error in a stack like this:

ORA-04068: existing state of packages has been discarded
ORA-04061: existing state of package body "schema.package" has been invalidated
ORA-04065: not executed, altered or dropped package body "schema.package"
ORA-06508: PL/SQL: could not find program unit being called: "schema.package"

If so, that's because your package is stateful:

The values of the variables, constants, and cursors that a package declares (in either its specification or body) comprise its package state. If a PL/SQL package declares at least one variable, constant, or cursor, then the package is stateful; otherwise, it is stateless.

When you recompile the state is lost:

If the body of an instantiated, stateful package is recompiled (either explicitly, with the "ALTER PACKAGE Statement", or implicitly), the next invocation of a subprogram in the package causes Oracle Database to discard the existing package state and raise the exception ORA-04068.

After PL/SQL raises the exception, a reference to the package causes Oracle Database to re-instantiate the package, which re-initializes it...

You can't avoid this if your package has state. I think it's fairly rare to really need a package to be stateful though, so you should revisit anything you have declared in the package, but outside a function or procedure, to see if it's really needed at that level. Since you're on 10g though, that includes constants, not just variables and cursors.

But the last paragraph from the quoted documentation means that the next time you reference the package in the same session, you won't get the error and it will work as normal (until you recompile again).

Dictionary<string, List<CustomObject>> myDictionary = ListOfCustomObjects
    .GroupBy(o => o.PropertyName)
    .ToDictionary(g => g.Key, g => g.ToList());

Yes there is a difference in the performance of both: jQuery('#id').show() is slower than jQuery('#id').css("display","block") as in former case extra work is to be done for retrieving the initial state from the jquery cache as display is not a binary attribute it can be inline,block,none,table, etc. similar is the case with hide() method.

See: http://jsperf.com/show-vs-addclass

You could use a variable to make the calculation and use toFixed when you set the #diskamountUnit element value:

var amount = $("#disk").slider("value") * 1.60;
$("#diskamountUnit").val('$' + amount.toFixed(2));

You can also do that in one step, in the val method call but IMO the first way is more readable:

$("#diskamountUnit").val('$' + ($("#disk").slider("value") * 1.60).toFixed(2));

This worked for me:

var dtFromMillisec = new Date(secs*1000);
var result = dtFromMillisec.getHours() + ":" + dtFromMillisec.getMinutes() + ":" + dtFromMillisec.getSeconds();

after you add the user for testing. the user should get an email. open that email by your iOS device, then click "Start testing" it will bring you to testFlight to download the app directly. If you open that email via computer, and then click "Start testing" it will show you another page which have the instruction of how to install the app. and that invitation code is on the last line. those All upper case letters is the code.

To install an APK on your mobile, you can either:

1. Use ADB from the Android SDK, and do the following command: adb install filename.apk. Note, you'll need to enable USB debugging for this to work.
2. Transfer the file to your device, then open it with a file manager, such as Linda File Manager.

Note, that you'll have to enable installing packages from Unknown Sources in your Applications settings.

As for getting USB to work, I suggest consulting the Android StackExchange for advice.

Usually 'lost' is a euphemism for "We stopped paying the developer and now he wont give us the source code."

I got this from YouTube Setting up Python Visual Studio Code... Venv

OK, the video really didn't help me all that much, but... the first comment under (by the person who posted the video) makes a lot of sense and is pure gold.

Basically, open up Visual Studio Code' built-in Terminal. Then source <your path>/activate.sh, the usual way you choose a venv from the command line. I have a predefined Bash function to find & launch the right script file and that worked just fine.

Quoting that YouTube comment directly (all credit to aneuris ap):

(you really only need steps 5-7)

1. Open your command line/terminal and type `pip virtualenv`.
2. Create a folder in which the virtualenv will be placed in.
3. 'cd' to the script folder in the virtualenv and run activate.bat (CMD).
4. Deactivate to turn of the virtualenv (CMD).
5. Open the project in Visual Studio Code and use its built-in terminal to 'cd' to the script folder in you virtualenv.
6. Type source activates (in Visual Studio Code I use the Git terminal).
7. Deactivate to turn off the virtualenv.

As you may notice, he's talking about activate.bat. So, if it works for me on a Mac, and it works on Windows too, chances are it's pretty robust and portable.

Just download and install "Samsung Kies" from this link. and everything would work as required.

Before installing, uninstall the drivers you have installed for your device.

Update:

Two possible solutions:

1. Try with the Google USB driver which comes with the SDK.
2. Download and install the Samsung USB driver from this link as suggested by Mauricio Gracia Gutierrez

A bit simplified you can think of it as arrays being a special case and not ordinary classes (a bit like primitives, but not). String and all the collections are classes, hence the methods to get size, length or similar things.

I guess the reason at the time of the design was performance. If they created it today they had probably come up with something like array-backed collection classes instead.

If anyone is interested, here is a small snippet of code to illustrate the difference between the two in generated code, first the source:

public class LengthTest {
  public static void main(String[] args) {
    int[] array = {12,1,4};
    String string = "Hoo";
    System.out.println(array.length);
    System.out.println(string.length());
  }
}

Cutting a way the not so important part of the byte code, running javap -c on the class results in the following for the two last lines:

20: getstatic   #3; //Field java/lang/System.out:Ljava/io/PrintStream;
23: aload_1
24: arraylength
25: invokevirtual   #4; //Method java/io/PrintStream.println:(I)V
28: getstatic   #3; //Field java/lang/System.out:Ljava/io/PrintStream;
31: aload_2
32: invokevirtual   #5; //Method java/lang/String.length:()I
35: invokevirtual   #4; //Method java/io/PrintStream.println:(I)V

In the first case (20-25) the code just asks the JVM for the size of the array (in JNI this would have been a call to GetArrayLength()) whereas in the String case (28-35) it needs to do a method call to get the length.

In the mid 1990s, without good JITs and stuff, it would have killed performance totally to only have the java.util.Vector (or something similar) and not a language construct which didn't really behave like a class but was fast. They could of course have masked the property as a method call and handled it in the compiler but I think it would have been even more confusing to have a method on something that isn't a real class.

For iOS 7 I use this,

-(void)tableView:(UITableView *)tableView willDisplayHeaderView:(UIView *)view forSection:(NSInteger)section
{
    UITableViewHeaderFooterView *header = (UITableViewHeaderFooterView *)view;

    header.textLabel.font = [UIFont boldSystemFontOfSize:10.0f];
    header.textLabel.textColor = [UIColor orangeColor];
}

Here is Swift 3.0 version with header resizing

override func tableView(_ tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int) {
    if let header = view as? UITableViewHeaderFooterView {
        header.textLabel!.font = UIFont.systemFont(ofSize: 24.0)
        header.textLabel!.textColor = UIColor.orange          
    }
}

I came up with this [untested]

import sys

class Tee(object):
    def __init__(self, *files):
        self.files = files
    def write(self, obj):
        for f in self.files:
            f.write(obj)
            f.flush() # If you want the output to be visible immediately
    def flush(self) :
        for f in self.files:
            f.flush()

f = open('out.txt', 'w')
original = sys.stdout
sys.stdout = Tee(sys.stdout, f)
print "test"  # This will go to stdout and the file out.txt

#use the original
sys.stdout = original
print "This won't appear on file"  # Only on stdout
f.close()

print>>xyz in python will expect a write() function in xyz. You could use your own custom object which has this. Or else, you could also have sys.stdout refer to your object, in which case it will be tee-ed even without >>xyz.

A simple DIY way would be to make the grid yourself:

import matplotlib.pyplot as plt

fig = plt.figure()
ax = fig.add_subplot(111)

ax.plot([1,2,3], [2,3,4], 'ro')

for xmaj in ax.xaxis.get_majorticklocs():
  ax.axvline(x=xmaj, ls='-')
for xmin in ax.xaxis.get_minorticklocs():
  ax.axvline(x=xmin, ls='--')

for ymaj in ax.yaxis.get_majorticklocs():
  ax.axhline(y=ymaj, ls='-')
for ymin in ax.yaxis.get_minorticklocs():
  ax.axhline(y=ymin, ls='--')
plt.show()

startInfo.Arguments = "/c \"netsh http add sslcert ipport=127.0.0.1:8085 certhash=0000000000003ed9cd0c315bbb6dc1c08da5e6 appid={00112233-4455-6677-8899-AABBCCDDEEFF} clientcertnegotiation=enable\"";

and...

startInfo.Arguments = "/c \"makecert -sk server -sky exchange -pe -n CN=localhost -ir LocalMachine -is Root -ic MyCA.cer -sr LocalMachine -ss My MyAdHocTestCert.cer\"";

The /c tells cmd to quit once the command has completed. Everything after /c is the command you want to run (within cmd), including all of the arguments.

Here are the steps (in-short), since I don't know what exactly you have done:
1. Download and install Git on your system: http://git-scm.com/downloads
2. Using the Git Bash (a command prompt for Git) or your system's native command prompt, set up a local git repository.
3. Use the same console to checkout, commit, push, etc. the files on the Git.

If you're trying to use the array as a generic HashMap key, that's not going to work. Consider creating a custom wrapper object that holds the array, and whose equals(...) and hashcode(...) method returns the results from the java.util.Arrays methods. For example...

import java.util.Arrays;

public class MyByteArray {
   private byte[] data;

   // ... constructors, getters methods, setter methods, etc...


   @Override
   public int hashCode() {
      return Arrays.hashCode(data);
   }

   @Override
   public boolean equals(Object obj) {
      if (this == obj)
         return true;
      if (obj == null)
         return false;
      if (getClass() != obj.getClass())
         return false;
      MyByteArray other = (MyByteArray) obj;
      if (!Arrays.equals(data, other.data))
         return false;
      return true;
   }


}

Objects of this wrapper class will work fine as a key for your HashMap<MyByteArray, OtherType> and will allow for clean use of equals(...) and hashCode(...) methods.

            string BinaryResult = "";

            while (Decimal > 0)
            {
                BinaryHolder = Decimal % 2;
                BinaryResult += BinaryHolder;
                Decimal = Decimal / 2;
            }

            // The algoritm gives us the binary number in reverse order (mirrored)
            // We store it in an array so that we can reverse it back to normal
            BinaryArray = BinaryResult.ToCharArray();
            Array.Reverse(BinaryArray);
            BinaryResult = new string(BinaryArray);

            return BinaryResult;
        }

Here is another approach, up to the OP to choose which one he prefers.

When including the code below in the __init__.py file before any other code, messages printed with print and any errors will no longer be logged to Ableton's Log.txt but to separate files on your disk:

import sys

path = "/Users/#username#"

errorLog = open(path + "/stderr.txt", "w", 1)
errorLog.write("---Starting Error Log---\n")
sys.stderr = errorLog
stdoutLog = open(path + "/stdout.txt", "w", 1)
stdoutLog.write("---Starting Standard Out Log---\n")
sys.stdout = stdoutLog

(for Mac, change #username# to the name of your user folder. On Windows the path to your user folder will have a different format)

When you open the files in a text editor that refreshes its content when the file on disk is changed (example for Mac: TextEdit does not but TextWrangler does), you will see the logs being updated in real-time.

Oh, dear. A few little problems...

As pointed out by others, you need to quote to protect against empty/space-containing entries, and use the !delayed_expansion! facility.

Two other matters of which you should be aware:

First, set/p will assign a user-input value to a variable. That's not news - but the gotcha is that pressing enter in response will leave the variable UNCHANGED - it will not ASSIGN a zero-length string to the variable (hence deleting the variable from the environment.) The safe method is:

 set "var="
 set /p var=

That is, of course, if you don't WANT enter to repeat the existing value.
Another useful form is

 set "var=default"
 set /p var=

or

 set "var=default"
 set /p "var=[%var%]"

(which prompts with the default value; !var! if in a block statement with delayedexpansion)

Second issue is that on some Windows versions (although W7 appears to "fix" this issue) ANY label - including a :: comment (which is a broken-label) will terminate any 'block' - that is, parenthesised compound statement)

Two way to truncate text into angular.

let str = 'How to truncate text in angular';

1. Solution

  {{str | slice:0:6}}

Output:

   how to

If you want to append any text after slice string like

   {{ (str.length>6)? (str | slice:0:6)+'..':(str) }}

Output:

 how to...

2. Solution(Create custom pipe)

if you want to create custom truncate pipe

import { Pipe, PipeTransform } from '@angular/core';

@Pipe({
 name: 'truncate'
})

export class TruncatePipe implements PipeTransform {

transform(value: string, args: any[]): string {
    const limit = args.length > 0 ? parseInt(args[0], 10) : 20;
    const trail = args.length > 1 ? args[1] : '...';
    return value.length > limit ? value.substring(0, limit) + trail : value;
   }
}

In Markup

{{ str | truncate:[20] }} // or 
{{ str | truncate:[20, '...'] }} // or

Don't forget to add a module entry.

@NgModule({
  declarations: [
    TruncatePipe
  ]
})
export class AppModule {}

   function readFromRegistry (strRegistryKey, strDefault )
    Dim WSHShell, value

    On Error Resume Next
    Set WSHShell = CreateObject("WScript.Shell")
    value = WSHShell.RegRead( strRegistryKey )

    if err.number <> 0 then
        readFromRegistry= strDefault
    else
        readFromRegistry=value
    end if

    set WSHShell = nothing
end function

Usage :

str = readfromRegistry("HKEY_LOCAL_MACHINE\SOFTWARE\Adobe\ESD\Install_Dir", "ha")
wscript.echo "returned " & str

int intNumber = (int)uintNumber;

Depending on what kind of values you are expecting, you may want to check how big uintNumber is before doing the conversion. An int has a max value of about .5 of a uint.

What helped me is, I tried to fetch and upload the last selected file using a loop, instead of clearing out the queue, and it worked. Here is the code.

for (int i = 0; i <= Request.Files.Count-1; i++)
{
 HttpPostedFileBase uploadfile = files[i];
 Stream fs = uploadfile.InputStream;
 BinaryReader br = new BinaryReader(fs);
 Byte[] imageBytes = br.ReadBytes((Int32)fs.Length);
}

Hope this might help some.

Converting to double can be done by casting an int to a double:

You can convert an int to a double by using this mechnism like so:

int i = 3; // i is 3
double d = (double) i; // d = 3.0

Alternative (using Java's automatic type recognition):

double d = 1.0 * i; // d = 3.0

Implementing this in your code would be something like:

double firstSolution = ((double)(b1 * a22 - b2 * a12) / (double)(a11 * a22 - a12 * a21));
double secondSolution = ((double)(b2 * a11 - b1 * a21) / (double)(a11 * a22 - a12 * a21));

Alternatively you can use a hard-parameter of type double (1.0) to have java to the work for you, like so:

double firstSolution = ((1.0 * (b1 * a22 - b2 * a12)) / (1.0 * (a11 * a22 - a12 * a21)));
double secondSolution = ((1.0 * (b2 * a11 - b1 * a21)) / (1.0 * (a11 * a22 - a12 * a21)));

Good luck.

Try this one..

var listCheck = [];
console.log($("input[name='YourCheckBokName[]']"));
$("input[name='YourCheckBokName[]']:checked").each(function() {
     console.log($(this).val());
     listCheck .push($(this).val());
});
console.log(listCheck);

This is another method I use because changing DropDownSyle to DropDownList makes it look 3D and sometimes its just plain ugly.

You can prevent user input by handling the KeyPress event of the ComboBox like this.

private void ComboBox1_KeyPress(object sender, KeyPressEventArgs e)
{
      e.Handled = true;
}

Like the others said, ISO C++ doesn't support that. But you can workaround it. Just use std::vector instead.

int* a = new int[N];
// fill a

class C {
  const std::vector<int> v;
public:
  C():v(a, a+N) {}
};

using ".intValue()" on BigDecimal object is not right when you want to check if its grater than zero. The only option left is ".compareTo()" method.

Try this:

foreach (Item item in myItemsList)
{
  if (SkipCondition) continue;
  // More stuff here
}

I'm surprised no-one has mentioned using LinkedList as a base for writing a specialised class.

Often we don't need the full API's of the various collection classes, and if you write mostly functional side effect free code, using immutable classes as far as possible, then you'll actually NOT want to mutate the collection favouring various snapshot implementations.

LinkedList solves some difficult problems of creating snapshot copies/clones of large collections. I also use it to create "threadsafe" enumerators to enumerate over the collection. I can cheat, because I know that I'm not changing the collection in any way other than appending, I can keep track of the list size, and only lock on changes to list size. Then my enumerator code simply enumerates from 0 to n for any thread that wants a "snapshot" of the append only collection, that will be guaranteed to represent a "snapshot" of the collection at any moment in time, regardless of what other threads are appending to the head of the collection.

I'm pretty certain that most requirements are often extremely simple, and you need 2 or 3 methods only. Writing a truly generic library is awfully difficult, but solving your own codes needs can sometimes be easy with a trick or two.

Long live LinkedList and good functional programming.

Remember to import base64 and that b64encode takes bytes as an argument.

import base64
base64.b64encode(bytes('your string', 'utf-8'))

Many ways this can be achieved.

Simple approach should be taking Substring of an input string.

var result = input.Substring(input.Length - 3);

Another approach using Regular Expression to extract last 3 characters.

var result = Regex.Match(input,@"(.{3})\s*$");

Do you use some AJAX framework? Using jQuery it would be:

$.getScript('script.js');

If you're not using any framework then see the answer by Harmen.

(Maybe it is not worth to use jQuery just to do this one simple thing (or maybe it is) but if you already have it loaded then you might as well use it. I have seen websites that have jQuery loaded e.g. with Bootstrap but still use the DOM API directly in a way that is not always portable, instead of using the already loaded jQuery for that, and many people are not aware of the fact that even getElementById() doesn't work consistently on all browsers - see this answer for details.)

UPDATE:

It's been years since I wrote this answer and I think it's worth pointing out here that today you can use:

• SystemJS
• ModuleLoader
• jspm.io

to dynamically load scripts. Those may be relevant to people reading this question.

Using HttpClient (Http's replacement) in Angular 4.3+, the entire mapping/casting process is made simpler/eliminated.

Using your CountryData class, you would define a service method like this:

getCountries()  {
  return this.httpClient.get<CountryData[]>('http://theUrl.com/all');
}

Then when you need it, define an array like this:

countries:CountryData[] = [];

and subscribe to it like this:

this.countryService.getCountries().subscribe(countries => this.countries = countries);

A complete setup answer is posted here also.

Another approach depending on how you are changing the div. If you are using JQuery to change a div's contents with its html() method, you can extend that method and call a registration function each time you put html into a div.

(function( $, oldHtmlMethod ){
    // Override the core html method in the jQuery object.
    $.fn.html = function(){
        // Execute the original HTML method using the
        // augmented arguments collection.

        var results = oldHtmlMethod.apply( this, arguments );
        com.invisibility.elements.findAndRegisterElements(this);
        return results;

    };
})( jQuery, jQuery.fn.html );

We just intercept the calls to html(), call a registration function with this, which in the context refers to the target element getting new content, then we pass on the call to the original jquery.html() function. Remember to return the results of the original html() method, because JQuery expects it for method chaining.

For more info on method overriding and extension, check out http://www.bennadel.com/blog/2009-Using-Self-Executing-Function-Arguments-To-Override-Core-jQuery-Methods.htm, which is where I cribbed the closure function. Also check out the plugins tutorial at JQuery's site.

This is a shortcut for $(document).ready(), which is executed when the browser has finished loading the page (meaning here, "when the DOM is available"). See http://www.learningjquery.com/2006/09/introducing-document-ready. If you are trying to call example() before the browser has finished loading the page, it may not work.

I think the question asker is (was) thinking that git bash is a command like git init or git checkout. Git bash is not a command, it is an interface. I will also assume the asker is not a linux user because bash is very popular the unix/linux world. The name "bash" is an acronym for "Bourne Again SHell". Bash is a text-only command interface that has features which allow automated scripts to be run. A good analogy would be to compare bash to the new PowerShell interface in Windows7/8. A poor analogy (but one likely to be more readily understood by more people) is the combination of the command prompt and .BAT (batch) command files from the days of DOS and early versions of Windows.

An updated version of Rails/ActiveRecord may support this syntax natively. It would look similar to:

Foo.where(foo: 'bar').or.where(bar: 'bar')

As noted in this pull request https://github.com/rails/rails/pull/9052

For now, simply sticking with the following works great:

Foo.where('foo= ? OR bar= ?', 'bar', 'bar')

Update: According to https://github.com/rails/rails/pull/16052 the or feature will be available in Rails 5

Update: Feature has been merged to Rails 5 branch

For me, I saw none of the MVC templates (except the bottom two), after installing Update 3 which installed all the Core stuff.

Solution

I downloaded most recent core preview...

It prompted me for "repair" and after it was done, bringing up VS indicated it was "Installing Templates" and they appeared!

Warning

Update 3 is a game changer in that the "preferred" way of doing things is to use dotnetcore. For example a console application now uses the new file stucture, other projects such as a Test Project still use the same folder structure as before. But MVC has changed. I'm not even sure what other "Web Developer Tools" work with dotnetcore right now.

Use this annotation

@RequestMapping(value = "/url", method = RequestMethod.GET, produces = {MediaType.APPLICATION_JSON})

Use Date convert to compare with date: Try This:

select * from table 
where TO_DATE(to_char(timespanColumn,'YYYY-MM-DD'),'YYYY-MM-DD') = to_timestamp('2018-03-26', 'YYYY-MM-DD')

Its an XML namespace. It is required when you use XHTML 1.0 or 1.1 doctypes or application/xhtml+xml mimetypes.

You should be using HTML5 doctype, then you don't need it for text/html. Better start from template like this :

<!DOCTYPE html>
<html>
    <head>
        <meta charset=utf-8 />
        <title>domcument title</title>
        <link rel="stylesheet" href="/stylesheet.css" type="text/css" />
    </head>
    <body>
            <!-- your html content -->
            <script src="/script.js"></script>
    </body>
</html>

When you have put your Doctype straight - do and validate you html and your css .
That usually will sove you layout issues.

In Rails 4.x (See http://edgeguides.rubyonrails.org/active_record_querying.html#not-conditions)

GroupUser.where.not(user_id: me)

In Rails 3.x

GroupUser.where(GroupUser.arel_table[:user_id].not_eq(me))

To shorten the length, you could store GroupUser.arel_table in a variable or if using inside the model GroupUser itself e.g., in a scope, you can use arel_table[:user_id] instead of GroupUser.arel_table[:user_id]

Ok now I've done my research, here is the deal:

In TDS protocol, SET NOCOUNT ON only saves 9-bytes per query while the text "SET NOCOUNT ON" itself is a whopping 14 bytes. I used to think that 123 row(s) affected was returned from server in plain text in a separate network packet but that's not the case. It's in fact a small structure called DONE_IN_PROC embedded in the response. It's not a separate network packet so no roundtrips are wasted.

I think you can stick to default counting behavior almost always without worrying about the performance. There are some cases though, where calculating the number of rows beforehand would impact the performance, such as a forward-only cursor. In that case NOCOUNT might be a necessity. Other than that, there is absolutely no need to follow "use NOCOUNT wherever possible" motto.

Here is a very detailed analysis about insignificance of SET NOCOUNT setting: http://daleburnett.com/2014/01/everything-ever-wanted-know-set-nocount/

Safari 7.0.5 still does not support notification for validation of input fields.

To overcome it is possible to write fallback script like this: http://codepen.io/ashblue/pen/KyvmA

To see what HTML5 / CSS3 features are supported by browsers check: http://caniuse.com/form-validation

function hasHtml5Validation () {
  //Check if validation supported && not safari
  return (typeof document.createElement('input').checkValidity === 'function') && 
    !(navigator.userAgent.search("Safari") >= 0 && navigator.userAgent.search("Chrome") < 0);
}

$('form').submit(function(){
    if(!hasHtml5Validation())
    {
        var isValid = true;
        var $inputs = $(this).find('[required]');
        $inputs.each(function(){
            var $input = $(this);
            $input.removeClass('invalid');
            if(!$.trim($input.val()).length)
            {
                isValid = false;
                $input.addClass('invalid');                 
            }
        });
        if(!isValid)
        {
            return false;
        }
    }
});

SASS / LESS:

input, select, textarea {
    @include appearance(none);
    border-radius: 0px;

    &.invalid {
        border-color: red !important;
    }
}

Try this to validate HTTP URLs (uriName is the URI you want to test):

Uri uriResult;
bool result = Uri.TryCreate(uriName, UriKind.Absolute, out uriResult) 
    && uriResult.Scheme == Uri.UriSchemeHttp;

Or, if you want to accept both HTTP and HTTPS URLs as valid (per J0e3gan's comment):

Uri uriResult;
bool result = Uri.TryCreate(uriName, UriKind.Absolute, out uriResult) 
    && (uriResult.Scheme == Uri.UriSchemeHttp || uriResult.Scheme == Uri.UriSchemeHttps);

If time_created is a unix timestamp (int), you should be able to use something like this:

DELETE FROM locks WHERE time_created < (UNIX_TIMESTAMP() - 600);

(600 seconds = 10 minutes - obviously)

Otherwise (if time_created is mysql timestamp), you could try this:

DELETE FROM locks WHERE time_created < (NOW() - INTERVAL 10 MINUTE)

An answer you didn't ask for that may be helpful, if you're doing the replacement in preparation for sending the string into alert() -- or anything else where a single quote character might trip you up.

str.replace("'",'\x27')

That will replace all single quotes with the hex code for single quote.

Here https://toddmotto.com/mastering-the-module-pattern you can find the pattern thoroughly explained. I would add that the second thing about modular JavaScript is how to structure your code in multiple files. Many folks may advice you here to go with AMD, yet I can say from experience that you will end up on some point with slow page response because of numerous HTTP requests. The way out is pre-compilation of your JavaScript modules (one per file) into a single file following CommonJS standard. Take a look at samples here http://dsheiko.github.io/cjsc/

During the install of python make sure you have "Install for all users" selected. Uninstall python and do a custom install and check "Install for all users".

Try this:

if(Math.floor(id) == id && $.isNumeric(id)) 
  alert('yes its an int!');

$.isNumeric(id) checks whether it's numeric or not
Math.floor(id) == id will then determine if it's really in integer value and not a float. If it's a float parsing it to int will give a different result than the original value. If it's int both will be the same.

Alt+Insert to edit text in Column Mode.

file type can be checked in other ways also. I believe this is the easiest way to check the uploaded file type.. if u are dealing with an image file then go for the following code. if you are dealing with a video file then replace the image check with a video check in the if block.. have fun

     $img_up = $_FILES['video_file']['type'];
$img_up_type = explode("/", $img_up);
$img_up_type_firstpart = $img_up_type[0];

if($img_up_type_firstpart == "image") { // image is the image file type, you can deal with video if you need to check video file type
/* do your logical code */
}

Heredoc syntax can be very useful:

// start the string with 3 <'s and then a word
// it doesn't have to be any particular string or length
// but it's common to make it in all caps.
echo <<< EOT
    in here is your string
    it has the same variable substitution rules
    as a double quoted string.
    when you end it, put the indicator word at the
    start of the line (no spaces before it)
    and put a semicolon after it
EOT;

You're probably aware of this, but just in case: it's much easier to just type shutdown -r (or whatever command you like) into the "Run" box and hit enter.

Saves leaving batch files lying around everywhere.

DECLARE @i AS FLOAT = 2 SELECT @i / 3 SELECT cast(@i / cast(3 AS DECIMAL(18,2))as decimal (18,2))

Both factor and result requires casting to be considered as decimals.

For strings list from 1(or whatever > 0) until end.

itens = ['car', 'house', 'moon', 'sun']

v = 0
for item in itens:
    b = itens[1 + v]
    print(b)
    print('any other command')
    if b == itens[-1]:
        print('End')
        break
    v += 1

In this case a relatively simple GROUP BY can work, but in general, when there are additional columns where you can't order by but you want them from the particular row which they are associated with, you can either join back to the detail using all the parts of the key or use OVER():

Run:

git remote prune origin

Deletes all stale tracking branches which have already been removed at origin but are still locally available in remotes/origin.

git gc --auto

'G arbage C ollection' - runs housekeeping tasks (compresses revisions, removes loose/inaccessible objects). The --auto flag first determines whether any work is required, and exits without doing anything if not.

Right now with using Spring-Boot 2.0.4 - { } won't work.

@RequestMapping

still has String[] as a value parameter, so declaration looks like this:

 @RequestMapping(value=["/","/index","/login","/home"], method = RequestMethod.GET)

** Update - Works With Spring-Boot 2.2**

 @RequestMapping(value={"/","/index","/login","/home"}, method = RequestMethod.GET)

rsvndump worked great for me migrating a repository from svnrepository.com to an Ubuntu server that I control.

How to install and use rsvndump on Ubuntu:

1. Install missing dependencies ("APR" and Subversion libraries)

   sudo apt-get install apache2-threaded-dev
   sudo apt-get install libsvn-dev
   

2. Install rsvndump

   wget http://prdownloads.sourceforge.net/rsvndump/rsvndump-0.5.5.tar.gz
   tar xvfz rsvndump-0.5.5.tar.gz
   cd rsvndump-0.5.5
   ./configure
   make
   sudo make install
   

3. Dump the remote SVN repository to a local file

   rsvndump http://my.svnrepository.com/svn/old_repo > old_repo_dump
   

4. Create a new repository and load in the local dump file

   sudo svnadmin create /opt/subversion/my_new_rep
   sudo svnadmin load --force-uuid /opt/subversion/my_new_repo < old_repo_dump
   

You can look into the regex module (the fuzzy section). I don't know if you can get the actual differences, but at least you can specify allowed number of different types of changes like insert, delete, and substitutions:

import regex
sequence = 'afrykanerskojezyczny'
queries = [ 'afrykanerskojezycznym', 'afrykanerskojezyczni', 
            'nieafrykanerskojezyczni' ]
for q in queries:
    m = regex.search(r'(%s){e<=2}'%q, sequence)
    print 'match' if m else 'nomatch'

The only specific reasons to set autocrlf to true are:

• avoid git status showing all your files as modified because of the automatic EOL conversion done when cloning a Unix-based EOL Git repo to a Windows one (see issue 83 for instance)
• and your coding tools somehow depends on a native EOL style being present in your file:
  • for instance, a code generator hard-coded to detect native EOL
  • other external batches (external to your repo) with regexp or code set to detect native EOL
  • I believe some Eclipse plugins can produce files with CRLF regardless on platform, which can be a problem.
  • You code with Notepad.exe (unless you are using a Windows 10 2018.09+, where Notepad respects the EOL character detected).

Unless you can see specific treatment which must deal with native EOL, you are better off leaving autocrlf to false (git config --global core.autocrlf false).

Note that this config would be a local one (because config isn't pushed from repo to repo)

If you want the same config for all users cloning that repo, check out "What's the best CRLF handling strategy with git?", using the text attribute in the .gitattributes file.

Example:

*.vcproj    text eol=crlf
*.sh        text eol=lf

Note: starting git 2.8 (March 2016), merge markers will no longer introduce mixed line ending (LF) in a CRLF file.
See "Make Git use CRLF on its “<<<<<<< HEAD” merge lines"

You can use android:progressDrawable="@drawable/seekbar" instead of android:background="@drawable/seekbar" .

progressDrawable used for the progress mode.

You should try with

android:minHeight

Defines the minimum height of the view. It is not guaranteed the view will be able to achieve this minimum height (for example, if its parent layout constrains it with less available height).

android:minWidth

Defines the minimum width of the view. It is not guaranteed the view will be able to achieve this minimum width (for example, if its parent layout constrains it with less available width)

    android:minHeight="25p"

I got this error when I only updated the jquery library without updating the jqueryui library in parallel. I was using jquery 1.8.3 with jqueryui 1.9.0. However, when I updated jquery 1.8.3 to 1.9.1 I got the above error. When I commented out the offending .close method lines, it then threw an error about not finding .browser in the jquery library which was deprecated in jquery 1.8.3 and removed from jquery 1.9.1. So bascially, the jquery 1.9.1 library was not compatible with the jquery ui 1.9.0 library despite the jquery ui download page saying it works with jquery 1.6+. Essentially, there are unreported bugs when trying to use differing versions of the two. If you use the jquery version that comes bundled with the jqueryui download, I'm sure you'll be fine, but it's when you start using different versions that you off the beaten path and get errors like this. So, in summary, this error is from mis-matched versions (in my case anyway).

$scope.legal_name = $sanitize($scope.legal_name);
    console.log("Name before function...",$scope.legal_name);

    var str = "";
    for(var i=0; i < $scope.legal_name.length; i++) {
        var charName = $scope.legal_name.charAt(i);
        if((charName == '&') && ($scope.legal_name.charAt(i + 1) == '#')){
            var count = 0;
            var subString = "";
            while(true) {
                if(($scope.legal_name.charCodeAt(i + 2 + count) > 47) && ($scope.legal_name.charCodeAt(i + 1 + count) < 58 )) {
                    subString = subString + $scope.legal_name.charAt(i + 2 + count);
                    count++;
                } else {
                    if(subString.length > 0) {
                        var value = parseInt(subString);
                        str = str + String.fromCharCode(value);
                        i = i + 1 + count;

Steps:
1. Add accept attribute to input tag
2. Validate with javascript
3. Add server side validation to verify if the content is really an expected file type

For HTML and javascript:

<html>
<body>
<input name="image" type="file" id="fileName" accept=".jpg,.jpeg,.png" onchange="validateFileType()"/>
<script type="text/javascript">
    function validateFileType(){
        var fileName = document.getElementById("fileName").value;
        var idxDot = fileName.lastIndexOf(".") + 1;
        var extFile = fileName.substr(idxDot, fileName.length).toLowerCase();
        if (extFile=="jpg" || extFile=="jpeg" || extFile=="png"){
            //TO DO
        }else{
            alert("Only jpg/jpeg and png files are allowed!");
        }   
    }
</script>
</body>
</html>

Explanation:

1. The accept attribute filters the files that will be displayed in the file chooser popup. However, it is not a validation. It is only a hint to the browser. The user can still change the options in the popup.
2. The javascript only validates for file extension, but cannot really verify if the select file is an actual jpg or png.
3. So you have to write for file content validation on server side.

Usually, if you have big python objects it's quite hard to format them. I personally prefer using some tools for that.

Here is python-beautifier - www.cleancss.com/python-beautify that instantly turns your data into customizable style.

Take a look in the code below.

First, we create custom layouts. In this case, four types.

even.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:background="#ff500000"
    android:layout_height="match_parent">

    <TextView
        android:id="@+id/text"
        android:textColor="@android:color/white"
        android:layout_width="match_parent"
        android:layout_gravity="center"
        android:textSize="24sp"
        android:layout_height="wrap_content" />

 </LinearLayout>

odd.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:background="#ff001f50"
    android:gravity="right"
    android:layout_height="match_parent">

    <TextView
        android:id="@+id/text"
        android:textColor="@android:color/white"
        android:layout_width="wrap_content"
        android:layout_gravity="center"
        android:textSize="28sp"
        android:layout_height="wrap_content"  />

 </LinearLayout>

white.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:background="#ffffffff"
    android:gravity="right"
    android:layout_height="match_parent">

    <TextView
        android:id="@+id/text"
        android:textColor="@android:color/black"
        android:layout_width="wrap_content"
        android:layout_gravity="center"
        android:textSize="28sp"
        android:layout_height="wrap_content"   />

 </LinearLayout>

black.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:background="#ff000000"
    android:layout_height="match_parent">

    <TextView
        android:id="@+id/text"
        android:textColor="@android:color/white"
        android:layout_width="wrap_content"
        android:layout_gravity="center"
        android:textSize="33sp"
        android:layout_height="wrap_content"   />

 </LinearLayout>

Then, we create the listview item. In our case, with a string and a type.

public class ListViewItem {
        private String text;
        private int type;

        public ListViewItem(String text, int type) {
            this.text = text;
            this.type = type;
        }

        public String getText() {
            return text;
        }

        public void setText(String text) {
            this.text = text;
        }

        public int getType() {
            return type;
        }

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

    }

After that, we create a view holder. It's strongly recommended because Android OS keeps the layout reference to reuse your item when it disappears and appears back on the screen. If you don't use this approach, every single time that your item appears on the screen Android OS will create a new one and causing your app to leak memory.

public class ViewHolder {
        TextView text;

        public ViewHolder(TextView text) {
            this.text = text;
        }

        public TextView getText() {
            return text;
        }

        public void setText(TextView text) {
            this.text = text;
        }

    }

Finally, we create our custom adapter overriding getViewTypeCount() and getItemViewType(int position).

public class CustomAdapter extends ArrayAdapter {

        public static final int TYPE_ODD = 0;
        public static final int TYPE_EVEN = 1;
        public static final int TYPE_WHITE = 2;
        public static final int TYPE_BLACK = 3;

        private ListViewItem[] objects;

        @Override
        public int getViewTypeCount() {
            return 4;
        }

        @Override
        public int getItemViewType(int position) {
            return objects[position].getType();
        }

        public CustomAdapter(Context context, int resource, ListViewItem[] objects) {
            super(context, resource, objects);
            this.objects = objects;
        }

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {

            ViewHolder viewHolder = null;
            ListViewItem listViewItem = objects[position];
            int listViewItemType = getItemViewType(position);


            if (convertView == null) {

                if (listViewItemType == TYPE_EVEN) {
                    convertView = LayoutInflater.from(getContext()).inflate(R.layout.type_even, null);
                } else if (listViewItemType == TYPE_ODD) {
                    convertView = LayoutInflater.from(getContext()).inflate(R.layout.type_odd, null);
                } else if (listViewItemType == TYPE_WHITE) {
                    convertView = LayoutInflater.from(getContext()).inflate(R.layout.type_white, null);
                } else {
                    convertView = LayoutInflater.from(getContext()).inflate(R.layout.type_black, null);
                }

                TextView textView = (TextView) convertView.findViewById(R.id.text);
                viewHolder = new ViewHolder(textView);

                convertView.setTag(viewHolder);

            } else {
                viewHolder = (ViewHolder) convertView.getTag();
            }

            viewHolder.getText().setText(listViewItem.getText());

            return convertView;
        }

    }

And our activity is something like this:

private ListView listView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main); // here, you can create a single layout with a listview

        listView = (ListView) findViewById(R.id.listview);

        final ListViewItem[] items = new ListViewItem[40];

        for (int i = 0; i < items.length; i++) {
            if (i == 4) {
                items[i] = new ListViewItem("White " + i, CustomAdapter.TYPE_WHITE);
            } else if (i == 9) {
                items[i] = new ListViewItem("Black " + i, CustomAdapter.TYPE_BLACK);
            } else if (i % 2 == 0) {
                items[i] = new ListViewItem("EVEN " + i, CustomAdapter.TYPE_EVEN);
            } else {
                items[i] = new ListViewItem("ODD " + i, CustomAdapter.TYPE_ODD);
            }
        }

        CustomAdapter customAdapter = new CustomAdapter(this, R.id.text, items);
        listView.setAdapter(customAdapter);
        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView adapterView, View view, int i, long l) {
                Toast.makeText(getBaseContext(), items[i].getText(), Toast.LENGTH_SHORT).show();
            }
        });

    }
}

now create a listview inside mainactivity.xml like this

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:context="com.example.shivnandan.gygy.MainActivity">

    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/AppTheme.AppBarOverlay">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            app:popupTheme="@style/AppTheme.PopupOverlay" />

    </android.support.design.widget.AppBarLayout>

    <include layout="@layout/content_main" />

    <ListView
        android:layout_width="match_parent"

        android:layout_height="match_parent"

        android:id="@+id/listView"
        android:layout_alignParentRight="true"
        android:layout_alignParentEnd="true"


        android:layout_marginTop="100dp" />

</android.support.design.widget.CoordinatorLayout>

Tried all the above, use the Firebase Assistant! It is the simplest way to solve this. First remove all the dependencies you added to the build.gradle (using the manual method) and then in Android Studio:

Click Tools > Firebase to open the Assistant window.

It really is as easy as that.

An example using Collections.

import java.util.Collections;
 ...
String commaSeparated = "item1 , item2 , item3";
ArrayList<String> items = new ArrayList<>();
Collections.addAll(items, commaSeparated.split("\\s*,\\s*"));
 ...

You should create an Intent object with a geo-URI:

String uri = String.format(Locale.ENGLISH, "geo:%f,%f", latitude, longitude);
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));
context.startActivity(intent);

If you want to specify an address, you should use another form of geo-URI: geo:0,0?q=address.

reference : https://developer.android.com/guide/components/intents-common.html#Maps

If you just want the largest value in the array use the max function. This will return the largest value, although not the corresponding key. It does not change the original array.

If you care about the the key you could then do

$key = array_search(max($array), $array)

(Edited to include @binaryLV's suggestion)

In cross-platform, lowest-common-denominator sh you use:

#!/bin/sh
value=`cat config.txt`
echo "$value"

In bash or zsh, to read a whole file into a variable without invoking cat:

#!/bin/bash
value=$(<config.txt)
echo "$value"

Invoking cat in bash or zsh to slurp a file would be considered a Useless Use of Cat.

Note that it is not necessary to quote the command substitution to preserve newlines.

See: Bash Hacker's Wiki - Command substitution - Specialities.

The best that I've been able to do is

$(this).closest('.modal').modal('toggle');

This gets the modal holding the DOM object you triggered the event on (guessing you're clicking a button). Gets the closest parent '.modal' and toggles it. Obviously only works because it's inside the modal you clicked.

You can however do this:

$(".modal:visible").modal('toggle');

This gets the modal that is displaying (since you can only have one open at a time), and triggers the 'toggle' This would not work without ":visible"

The definitive solution is to allow the InfoTech protocol to work in the intranet zone.

Add the following value to the registry and the problem should be solved:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\ItssRestrictions]
"MaxAllowedZone"=dword:00000001

As mentioned in JavaDoc (https://docs.oracle.com/javase/7/docs/api/java/util/concurrent/CountDownLatch.html), CountDownLatch is a synchronization aid, introduced in Java 5. Here the synchronization does not mean restricting access to a critical section. But rather sequencing actions of different threads. The type of synchronization achieved through CountDownLatch is similar to that of Join. Assume that there is a thread "M" which needs to wait for other worker threads "T1", "T2", "T3" to complete its tasks Prior to Java 1.5, the way this can be done is, M running the following code

    T1.join();
    T2.join();
    T3.join();

The above code makes sure that thread M resumes its work after T1, T2, T3 completes its work. T1, T2, T3 can complete their work in any order. The same can be achieved through CountDownLatch, where T1,T2, T3 and thread M share same CountDownLatch object.
"M" requests : countDownLatch.await();
where as "T1","T2","T3" does countDownLatch.countdown();

One disadvantage with the join method is that M has to know about T1, T2, T3. If there is a new worker thread T4 added later, then M has to be aware of it too. This can be avoided with CountDownLatch. After implementation the sequence of action would be [T1,T2,T3](the order of T1,T2,T3 could be anyway) -> [M]

glob2rx() converts a pattern including a wildcard into the equivalent regular expression. You then need to pass this regular expression onto one of R's pattern matching tools.

If you want to match "blue*" where * has the usual wildcard, not regular expression, meaning we use glob2rx() to convert the wildcard pattern into a useful regular expression:

> glob2rx("blue*")
[1] "^blue"

The returned object is a regular expression.

Given your data:

x <- c('red','blue1','blue2', 'red2')

we can pattern match using grep() or similar tools:

> grx <- glob2rx("blue*")
> grep(grx, x)
[1] 2 3
> grep(grx, x, value = TRUE)
[1] "blue1" "blue2"
> grepl(grx, x)
[1] FALSE  TRUE  TRUE FALSE

As for the selecting rows problem you posted

> a <- data.frame(x =  c('red','blue1','blue2', 'red2'))
> with(a, a[grepl(grx, x), ])
[1] blue1 blue2
Levels: blue1 blue2 red red2
> with(a, a[grep(grx, x), ])
[1] blue1 blue2
Levels: blue1 blue2 red red2

or via subset():

> with(a, subset(a, subset = grepl(grx, x)))
      x
2 blue1
3 blue2

Hope that explains what grob2rx() does and how to use it?

c# code

int i = 0;
char c = '?';
i = (int)c;
Console.WriteLine(i); // prints 8593

int j = 0;
char d = '?';
j = (int)d;
Console.WriteLine(j); // prints 8595

In addressing your comment that you need your current time, and not the system time, you will have to make an adjustment yourself, there are 3600 seconds in an hour (the unit timestamps use), so use that. for example, if your system time was one hour behind:

$time = date('H:i',time() + 3600);

Here's a non-standard but cross-browser method that may be useful if you don't want to pass any arguments:-

Html:

<div onclick=myHandler() id="my element's id">&rarr; Click Here! &larr;</div>

Script:

function myHandler(){
    alert(myHandler.caller.arguments[0].target.id)
}

Demo: http://codepen.io/mrmoje/pen/ouJtk

unreserved = ALPHA / DIGIT / "-" / "." / "_" / "~"

Here's a trick that worked for me:

handleClick = e => {
    if (e.target === e.currentTarget) {
        // do something
    } else {
        // do something else
    }
}

Explanation: I attached handleClick to a backdrop of a modal window, but it also fired on every click inside of a modal window (because it was IN the backdrop div). So I added the condition (e.target === e.currentTarget), which is only fulfilled when a backdrop is clicked.

A postback is the process of re-loading a page, so if you want the page to close after the postback then you need to set your window.close() javascript to run with the browser's onload event during that postback, normally done using the ClientScript.RegisterStartupScript() function.

But are you sure this is what you want to do? Closing pages tends to piss off users.

Many description internet-wide don't mention that specifying Access-Control-Allow-Origin is not enough. Here is a complete example that works for me:

<?php
    if ($_SERVER['REQUEST_METHOD'] === 'OPTIONS') {
        header('Access-Control-Allow-Origin: *');
        header('Access-Control-Allow-Methods: POST, GET, DELETE, PUT, PATCH, OPTIONS');
        header('Access-Control-Allow-Headers: token, Content-Type');
        header('Access-Control-Max-Age: 1728000');
        header('Content-Length: 0');
        header('Content-Type: text/plain');
        die();
    }

    header('Access-Control-Allow-Origin: *');
    header('Content-Type: application/json');

    $ret = [
        'result' => 'OK',
    ];
    print json_encode($ret);

I found one solution for assign variables to COLUMN or TABLE:

conn = sqlite3.connect('database.db')
cursor=conn.cursor()
z="Cash_payers"   # bring results from Table 1 , Column: Customers and COLUMN 
# which are pays cash
sorgu_y= Customers #Column name
query1="SELECT  * FROM  Table_1 WHERE " +sorgu_y+ " LIKE ? "
print (query1)
query=(query1)
cursor.execute(query,(z,))

Don't forget input one space between the WHERE and double quotes and between the double quotes and LIKE

You must check if the same JAR is being imported again. In my case there was a class inside a jar which was getting imported in another jar. So just check if the any lib / class file is being included twice in the whole project!

If you are using PHPMyAdmin You can be solved this issue by doing this:

CAUTION: Don't use this solution if you want to maintain existing records in your table.

Step 1: Select database export method to custom:

Step 2: Please make sure to check truncate table before insert in data creation options:

Now you are able to import this database successfully.

This would be work very fine

<a href="<%:Url.Action("Edit","Account",new {  id=item.UserId }) %>"><img src="../../Content/ThemeNew/images/edit_notes_delete11.png" alt="Edit" width="25px" height="25px" /></a>

Three years past since this question was answered but I will provide my answer anyway :)

Actually, accepted answer is not fully correct. Jakub's test uses hardcoded string which allows JS engine to optimize code execution (Google's V8 is really good in this stuff!). But as soon as you use completely random strings (here is JSPerf) then string concatenation will be on a second place.

Perhaps the easiest way would be to add an image, scale it, and set it to the JFrame/JPanel (in my case JPanel) but remember to "add" it to the container only after you've added the other children components.

    ImageIcon background=new ImageIcon("D:\\FeedbackSystem\\src\\images\\background.jpg");
    Image img=background.getImage();
    Image temp=img.getScaledInstance(500,600,Image.SCALE_SMOOTH);
    background=new ImageIcon(temp);
    JLabel back=new JLabel(background);
    back.setLayout(null);
    back.setBounds(0,0,500,600);

I would avoid using a relative path. Remember that docker is a daemon/client relationship.

When you are executing the compose, it's essentially just breaking down into various docker client commands, which are then passed to the daemon. That ./database is then relative to the daemon, not the client.

Now, the docker dev team has some back and forth on this issue, but the bottom line is it can have some unexpected results.

In short, don't use a relative path, use an absolute path.

That's the problem. I've outputted a bunch of information (including the HTML to build the login page itself). So how do I redirect the user from one page to the next?

This means your application design is pretty broken. You shouldn't be doing output while your business logic is running. Go an use a template engine (like Smarty) or quickfix it by using output buffering).

Another option (not a good one though!) would be outputting JavaScript to redirect:

<script type="text/javascript">location.href = 'newurl';</script>

Insertion sort can be resumed as "Look for the element which should be at first position(the minimum), make some space by shifting next elements, and put it at first position. Good. Now look at the element which should be at 2nd...." and so on...

Bubble sort operate differently which can be resumed as "As long as I find two adjacent elements which are in the wrong order, I swap them".

You can use URL Encoding Functions PHP has the

rawurlencode() 

function

ASP has the

Server.URLEncode() 

function

In JavaScript you can use the

encodeURIComponent() 

function.

I do it like this:

(Shortened the code a bit)

public struct Age
{
    public readonly int Years;
    public readonly int Months;
    public readonly int Days;

}

public Age( int y, int m, int d ) : this()
{
    Years = y;
    Months = m;
    Days = d;
}

public static Age CalculateAge ( DateTime birthDate, DateTime anotherDate )
{
    if( startDate.Date > endDate.Date )
        {

Since the event object "evt" is not passed from the parameter, is it still possible to obtain this object?

No, not reliably. IE and some other browsers make it available as window.event (not $(window.event)), but that's non-standard and not supported by all browsers (famously, Firefox does not).

You're better off passing the event object into the function:

<a href="#" onclick="myFunc(event, 1,2,3)">click</a>

That works even on non-IE browsers because they execute the code in a context that has an event variable (and works on IE because event resolves to window.event). I've tried it in IE6+, Firefox, Chrome, Safari, and Opera. Example: http://jsbin.com/iwifu4

But your best bet is to use modern event handling:

HTML:

<a href="#">click</a>

JavaScript using jQuery (since you're using jQuery):

$("selector_for_the_anchor").click(function(event) {
    // Call `myFunc`
    myFunc(1, 2, 3);

    // Use `event` here at the event handler level, for instance
    event.stopPropagation();
});

...or if you really want to pass event into myFunc:

$("selector_for_the_anchor").click(function(event) {
    myFunc(event, 1, 2, 3);
});

The selector can be anything that identifies the anchor. You have a very rich set to choose from (nearly all of CSS3, plus some). You could add an id or class to the anchor, but again, you have other choices. If you can use where it is in the document rather than adding something artificial, great.

The best

• mod_cband (Best featured for 'normal' bandwidth control)

and the rest

• mod_limitipconn
• mod_bw

Try setting the core.autocrlf configuration option to true. Also have a look at the core.safecrlf option.

Actually it sounds like core.safecrlf might already be set in your repository, because (emphasis mine):

If this is not the case for the current setting of core.autocrlf, git will reject the file.

If this is the case, then you might want to check that your text editor is configured to use line endings consistently. You will likely run into problems if a text file contains a mixture of LF and CRLF line endings.

Finally, I feel that the recommendation to simply "use what you're given" and use LF terminated lines on Windows will cause more problems than it solves. Git has the above options to try to handle line endings in a sensible way, so it makes sense to use them.

Based on your comment it looks like your'e only adding the new column if: mysql_query("SELECT * FROM assessment"); returns false. That's probably not what you wanted. Try removing the '!' on front of $sql in the first 'if' statement. So your code will look like:

$sql=mysql_query("SELECT * FROM assessment");
if ($sql) {
 mysql_query("ALTER TABLE assessment ADD q6 INT(1) NOT NULL AFTER q5");
 echo 'Q6 created'; 
}else...

This isn't a "slice", but it is a general solution that doesn't use explicit indexing, and works for the scenario where the sequence in question is anonymous (so you can create and "slice" on the same line, without creating twice and indexing twice): operator.itemgetter

import operator

# Done once and reused
first_and_last = operator.itemgetter(0, -1)

...

first, last = first_and_last(some_list)

You could just inline it as (after from operator import itemgetter for brevity at time of use):

first, last = itemgetter(0, -1)(some_list)

but if you'll be reusing the getter a lot, you can save the work of recreating it (and give it a useful, self-documenting name) by creating it once ahead of time.

Thus, for your specific use case, you can replace:

x, y = a.split("-")[0], a.split("-")[-1]

with:

x, y = itemgetter(0, -1)(a.split("-"))

and split only once without storing the complete list in a persistent name for len checking or double-indexing or the like.

Note that itemgetter for multiple items returns a tuple, not a list, so if you're not just unpacking it to specific names, and need a true list, you'd have to wrap the call in the list constructor.

[Quick Answer]

You have many alternatives, for example:

• Alternative 1:

  git rebase -i <YourCommitId>~1
  

  Change YourCommitId for the number of the commit which you want to revert back to.

• Alternative 2:

  git reset --hard YourCommitId
  git push <origin> <branch> --force
  

  Change YourCommitId for the number of the commit which you want to revert back to.

  I don't recommend this option because you can lost your work in progress.

• Alternative 3:

  git reset --soft HEAD~1
  

  You can keep your work and only undo the commit.

Here is a well tested function which i used for my projects with detailed self explanatory comments

There are many times when the ports other than 80 are blocked by server firewall so the code appears to be working fine on localhost but not on the server

function get_page($url){

global $proxy;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
//curl_setopt($ch, CURLOPT_PROXY, $proxy);
curl_setopt($ch, CURLOPT_HEADER, 0); // return headers 0 no 1 yes
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // return page 1:yes
curl_setopt($ch, CURLOPT_TIMEOUT, 200); // http request timeout 20 seconds
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); // Follow redirects, need this if the url changes
curl_setopt($ch, CURLOPT_MAXREDIRS, 2); //if http server gives redirection responce
curl_setopt($ch, CURLOPT_USERAGENT,
    "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.7) Gecko/20070914 Firefox/2.0.0.7");
curl_setopt($ch, CURLOPT_COOKIEJAR, "cookies.txt"); // cookies storage / here the changes have been made
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookies.txt");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // false for https
curl_setopt($ch, CURLOPT_ENCODING, "gzip"); // the page encoding

$data = curl_exec($ch); // execute the http request
curl_close($ch); // close the connection
return $data;
}

strstr didn't exist back then?

if(strstr($_SERVER['REQUEST_URI'], "car")) {
   echo "car found";
}

This must be one of the easiest methods right?

If you have a List<List<int>> k you can do

List<int> flatList= k.SelectMany( v => v).ToList();

Note: Git 2.6 (Q3/Q4 2015) will finally provide a more meaningful error message.

See commit ce11360 (29 Aug 2015) by Jeff King (peff).

log: diagnose empty HEAD more clearly

If you init or clone an empty repository, the initial message from running "git log" is not very friendly:

$ git init
Initialized empty Git repository in /home/peff/foo/.git/
$ git log
fatal: bad default revision 'HEAD'

Let's detect this situation and write a more friendly message:

$ git log
fatal: your current branch 'master' does not have any commits yet

We also detect the case that 'HEAD' points to a broken ref; this should be even less common, but is easy to see.
Note that we do not diagnose all possible cases. We rely on resolve_ref, which means we do not get information about complex cases. E.g., "--default master" would use dwim_ref to find "refs/heads/master", but we notice only that "master" does not exist.
Similarly, a complex sha1 expression like "--default HEAD^2" will not resolve as a ref.

But that's OK. We fall back to a generic error message in those cases, and they are unlikely to be used anyway.
Catching an empty or broken "HEAD" improves the common case, and the other cases are not regressed.

I use directive to prevent default behaviour:

module.directive('preventDefault', function() {
    return function(scope, element, attrs) {
        angular.element(element).bind('click', function(event) {
            event.preventDefault();
            event.stopPropagation();
        });
    }
});

And then, in html:

<button class="secondaryButton" prevent-default>Secondary action</button>

This directive can also be used with <a> and all other tags

It's fairly easy using the New-SelfSignedCertificate command in Powershell. Open powershell and run these 3 commands.

1) Create certificate:
$cert = New-SelfSignedCertificate -DnsName www.yourwebsite.com -Type CodeSigning -CertStoreLocation Cert:\CurrentUser\My

2) set the password for it:
$CertPassword = ConvertTo-SecureString -String "my_passowrd" -Force –AsPlainText

3) Export it:
Export-PfxCertificate -Cert "cert:\CurrentUser\My\$($cert.Thumbprint)" -FilePath "d:\selfsigncert.pfx" -Password $CertPassword

Your certificate selfsigncert.pfx will be located @ D:/

Optional step: You would also require to add certificate password to system environment variables. do so by entering below in cmd: setx CSC_KEY_PASSWORD "my_password"

You need to typecast the input. try using the following

int input = Convert.ToInt32(Console.ReadLine()); 

It will throw exception if the value is non-numeric.

Edit

I understand that the above is a quick one. I would like to improve my answer:

String input = Console.ReadLine();
int selectedOption;
if(int.TryParse(input, out selectedOption))
{
      switch(selectedOption) 
      {
           case 1:
                 //your code here.
                 break;
           case 2:
                //another one.
                break;
           //. and so on, default..
      }

} 
else
{
     //print error indicating non-numeric input is unsupported or something more meaningful.
}

In your example, it’s fine as it is: it’s simple and works. The only things I’d suggest are:

1. validating the data POSTed

2. make sure your API is sending the Content-Type header to tell the client to expect a JSON response:

   header('Content-Type: application/json');
   echo json_encode($response);
   

Other than that, an API is something that takes an input and provides an output. It’s possible to “over-engineer” things, in that you make things more complicated that need be.

If you wanted to go down the route of controllers and models, then read up on the MVC pattern and work out how your domain objects fit into it. Looking at the above example, I can see maybe a MathController with an add() action/method.

There are a few starting point projects for RESTful APIs on GitHub that are worth a look.

To update other branches like (backup) with your master branch copy. You can do follow either way (rebase or merge)...

1. Do rebase (there won't be any extra commit made to the backup branch).

2. Merge branches (there will be an extra commit automatically to the backup branch).

   Note : Rebase is nothing but establishing a new base (a new copy)

git checkout backup
git merge master
git push

(Repeat for other branches if any like backup2 & etc..,)

git checkout backup
git rebase master
git push

(Repeat for other branches if any like backup2 & etc..,)

to simply remove it, paste your xml file into notepad, you'll see the extra character before the first tag. Remove it & paste back into your file - bof

Convert GPS to UTM

http://www.ibm.com/developerworks/java/library/j-coordconvert/ http://stackoverflow.com/questions/176137/java-convert-lat-lon-to-utm

UTM coordinates get you a simples X Y 2D

Calculate the angle between both UTM locations

http://forums.groundspeak.com/GC/index.php?showtopic=146917

This gives the direction as if you were looking north

So whatever you rotate related do North just subtract this angle

If both point have a UTM 45º degree angle and you are 5º east of north, your arrow will point to 40º of north

I have a simple solution. Create a new Image asset by right clicking your package name and selecting New->Image asset. Enter name (any name) and path (location of image in your system). Then click Next and Finish. If you enter name of image as 'img', a round image with the name 'img_round' is created automatically in mipmap folder.

Then, do this :

<ImageView
        android:layout_width="100dp"
        android:layout_height="100dp"
        android:src="@mipmap/img_round"/>

Your preview may still show a rectangular image. But if you run the app on your device, it will be round.

In C++11, use std::to_string if you can accept the default format (%f).

storedCorrect[count]= "(" + std::to_string(c1) + ", " + std::to_string(c2) + ")";

You can actualy fake the transparency of option DOMElements with the following CSS:

option { 
    /* Whatever color  you want */
    background-color: #82caff;
}

The option tag does not support rgba colors yet.

I get a better result setting this class:

  z-index: 10040;
  overflow: auto;
  overflow-y: auto;
