Another sneaky issue related to this is naming your columns with - instead of _.

Something like this will trigger an error at the moment your tables are getting created.

@Column(name="verification-token")

You don't need hibernate-entitymanager-xxx.jar, because of you use a Hibernate session approach (not JPA). You need to close the SessionFactory too and rollback a transaction on errors. But, the problem, of course, is not with those.

This is returned by a database

#
org.postgresql.util.PSQLException: FATAL: password authentication failed for user "sa"
#

Looks like you've provided an incorrect username or (and) password.

I have had the same issue, but in a class that was not a part of the service layer. In my case, the transaction manager was simply obtained from the context by the getBean() method, and the class belonged to the view layer - my project utilizes OpenSessionInView technique.

The sessionFactory.getCurrentSession() method, has been causing the same exception as the author's. The solution for me was rather simple.

Session session;

try {
    session = sessionFactory.getCurrentSession();
} catch (HibernateException e) {
    session = sessionFactory.openSession();
}

If the getCurrentSession() method fails, the openSession() should do the trick.

@JsonIgnoreProperties({"hibernateLazyInitializer","handler"})

it works for me

What is wrong here is that your session management configuration is set to close session when you commit transaction. Check if you have something like:

<property name="current_session_context_class">thread</property>

in your configuration.

In order to overcome this problem you could change the configuration of session factory or open another session and only than ask for those lazy loaded objects. But what I would suggest here is to initialize this lazy collection in getModelByModelGroup itself and call:

Hibernate.initialize(subProcessModel.getElement());

when you are still in active session.

And one last thing. A friendly advice. You have something like this in your method:

for (Model m : modelList) {
    if (m.getModelType().getId() == 3) {
        model = m;
        break;
    }
}

Please insted of this code just filter those models with type id equal to 3 in the query statement just couple of lines above.

The below steps should be the simple fix to your problem

1. Project->Properties->ProjectFacet-->Uncheck jsf apply and OK.
2. Project->Maven->UpdateProject-->This will solve the issue.

Here while on Updating Project Maven will automatically chooses the Dynamic web module

I have the same problem a few months ago. This solve my problem using Maven instead of a downloaded version of Spring and some changes in the web.xml.

Something weird happen when I try to solve this. Any downloaded version of Spring from maven.springframework.org/release/org/springframework/spring gives me a lot of problems (Tomcat couldn't find servlet, Spring stops Tomcat, Eclipse couldn't start the server {weird}) so with many problems find many partial solutions. I hope this works for you.

As an extra help, in Eclipse, download from the Eclipse Marketplace the Spring STS Tool for Eclipse, this will help you to create configuration files (servlet.xml) and write code for the servlet in the web.xml file.

Check your Hibernate mapping file *.hbm.xml and check the class with which you are creating the getter and setter methods. Every property in the mapping file should exist as getters and setters in the populating class. Once you fix that the error is solved.

Also by reading the console, you can probably see the error mentioning a missing getter/setter.

Hope this helps you.

According to the stack trace, your issue is that your app cannot find org.apache.commons.dbcp.BasicDataSource, as per this line:

java.lang.ClassNotFoundException: org.apache.commons.dbcp.BasicDataSource

I see that you have commons-dbcp in your list of jars, but for whatever reason, your app is not finding the BasicDataSource class in it.

Finally, it turned out to be a missing artifact of solr that seemed to block all the rest of my build cycle.

I have no idea why mvn behaves like that, but upgrading to the latest version fixed it.

I tried @JsonDetect and

@JsonIgnoreProperties(value = { "handler", "hibernateLazyInitializer" })

Neither of them worked for me. Using a third-party module seemed like a lot of work to me. So I just tried making a get call on any property of the lazy object before passing to jackson for serlization. The working code snippet looked something like this :

@RequestMapping(value = "/authenticate", produces = "application/json; charset=utf-8")
    @ResponseBody
    @Transactional
    public Account authenticate(Principal principal) {
        UsernamePasswordAuthenticationToken usernamePasswordAuthenticationToken = (UsernamePasswordAuthenticationToken) principal;
        LoggedInUserDetails loggedInUserDetails = (LoggedInUserDetails) usernamePasswordAuthenticationToken.getPrincipal();
        User user = userRepository.findOne(loggedInUserDetails.getUserId());
        Account account = user.getAccount();
        account.getFullName();      //Since, account is lazy giving it directly to jackson for serlization didn't worked & hence, this quick-fix.
        return account;
    }

Try adding JRE System Library in the build path of your project.

Use XStream toXML/fromXML in memory. Extremely fast and has been around for a long time and is going strong. Objects don't need to be Serializable and you don't have use reflection (although XStream does). XStream can discern variables that point to the same object and not accidentally make two full copies of the instance. A lot of details like that have been hammered out over the years. I've used it for a number of years and it is a go to. It's about as easy to use as you can imagine.

new XStream().toXML(myObj)

or

new XStream().fromXML(myXML)

To clone,

new XStream().fromXML(new XStream().toXML(myObj))

More succinctly:

XStream x = new XStream();
Object myClone = x.fromXML(x.toXML(myObj));

This generally means that the owning Hibernate session has already closed. You can do one of the following to fix it:

1. whichever object creating this problem, use HibernateTemplate.initialize(object name)
2. Use lazy=false in your hbm files.

The best explanation to me is given here

What is JNDI

It is an API to providing access to a directory service, that is, a service mapping name (strings) with objects, reference to remote objects or simple data. This is called binding. The set of bindings is called the context. Applications use the JNDI interface to access resources.

To put it very simply, it is like a hashmap with a String key and Object values representing resources on the web.

What Issues Does JNDI Solve

Without JNDI, the location or access information of remote resources would have to be hard-coded in applications or made available in a configuration. Maintaining this information is quite tedious and error prone.

If a resources has been relocated on another server, with another IP address, for example, all applications using this resource would have to be updated with this new information. With JNDI, this is not necessary. Only the corresponding resource binding has to be updated. Applications can still access it with its name and the relocation is transparent.

Back in 2016 when this question was originally asked, the answer was:

$('.pull-right').addClass('pull-xs-right').removeClass('pull-right')

But now the accepted answer should be Robert Went's.

for ST3

$language = "language u wish"

if exists,

go to ~/.config/sublime-text-3/Packages/User/$language.sublime-settings

else

create ~/.config/sublime-text-3/Packages/User/$language.sublime-settings

and set

{ "extensions": [ "yourextension" ] }

This way allows you to enable syntax for composite extensions (e.g. sql.mustache, js.php, etc ... )

public class TestModels
{
    public Dictionary<int, dynamic> sp = new Dictionary<int, dynamic>();

    public TestModels()
    {
        sp.Add(0, new {name="Test One", age=5});
        sp.Add(1, new {name="Test Two", age=7});
    }
}

const dates = getDatesFromDateRange("2014-05-02", "2018-05-12", "YYYY/MM/DD", 1);           
console.log(dates);
// you get the whole from-to date ranges as per parameters
var onlyStartDates = dates.map(dateObj => dateObj["to"]);
console.log(onlyStartDates);
// moreover, if you want only from dates then you can grab by "map" function

function getDatesFromDateRange( startDate, endDate, format, counter ) {
    startDate = moment(startDate, format);
    endDate = moment(endDate, format);

    let dates = [];
    let fromDate = startDate.clone();
    let toDate = fromDate.clone().add(counter, "month").startOf("month").add(-1, "day");
    do {
        dates.push({
            "from": fromDate.format(format),
            "to": ( toDate < endDate ) ? toDate.format(format) : endDate.format(format)
        });
        fromDate = moment(toDate, format).add(1, "day").clone();
        toDate = fromDate.clone().add(counter, "month").startOf("month").add(-1, "day");
    } while ( fromDate < endDate );
    return dates;
}

Please note, .clone() is essential in momentjs else it'll override the value. It seems in your case.

It's more generic, to get bunch of dates that fall between dates.

Pluses:

First: mild, defeatable obfuscation.

Second: if compilation results in a significantly smaller file, you will get faster load times. Nice for the web.

Third: Python can skip the compilation step. Faster at intial load. Nice for the CPU and the web.

Fourth: the more you comment, the smaller the .pyc or .pyo file will be in comparison to the source .py file.

Fifth: an end user with only a .pyc or .pyo file in hand is much less likely to present you with a bug they caused by an un-reverted change they forgot to tell you about.

Sixth: if you're aiming at an embedded system, obtaining a smaller size file to embed may represent a significant plus, and the architecture is stable so drawback one, detailed below, does not come into play.

Top level compilation

It is useful to know that you can compile a top level python source file into a .pyc file this way:

python -m py_compile myscript.py

This removes comments. It leaves docstrings intact. If you'd like to get rid of the docstrings as well (you might want to seriously think about why you're doing that) then compile this way instead...

python -OO -m py_compile myscript.py

...and you'll get a .pyo file instead of a .pyc file; equally distributable in terms of the code's essential functionality, but smaller by the size of the stripped-out docstrings (and less easily understood for subsequent employment if it had decent docstrings in the first place). But see drawback three, below.

Note that python uses the .py file's date, if it is present, to decide whether it should execute the .py file as opposed to the .pyc or .pyo file --- so edit your .py file, and the .pyc or .pyo is obsolete and whatever benefits you gained are lost. You need to recompile it in order to get the .pyc or .pyo benefits back again again, such as they may be.

Drawbacks:

First: There's a "magic cookie" in .pyc and .pyo files that indicates the system architecture that the python file was compiled in. If you distribute one of these files into an environment of a different type, it will break. If you distribute the .pyc or .pyo without the associated .py to recompile or touch so it supersedes the .pyc or .pyo, the end user can't fix it, either.

Second: If docstrings are skipped with the use of the -OO command line option as described above, no one will be able to get at that information, which can make use of the code more difficult (or impossible.)

Third: Python's -OO option also implements some optimizations as per the -O command line option; this may result in changes in operation. Known optimizations are:

• sys.flags.optimize = 1
• assert statements are skipped
• __debug__ = False

Fourth: if you had intentionally made your python script executable with something on the order of #!/usr/bin/python on the first line, this is stripped out in .pyc and .pyo files and that functionality is lost.

Fifth: somewhat obvious, but if you compile your code, not only can its use be impacted, but the potential for others to learn from your work is reduced, often severely.

There is no way to get the old password back. Log into the SQL server management console as a machine or domain admin using integrated authentication, you can then change any password (including sa).

Start the SQL service again and use the new created login (recovery in my example) Go via the security panel to the properties and change the password of the SA account.

Now write down the new SA password.

One option is to use Outlook. We have a mail manager application that access an exchange server and uses outlook as the interface. Its dirty but it works.

Example code:

public Outlook.MAPIFolder getInbox()
        {
            mailSession = new Outlook.Application();
            mailNamespace = mailSession.GetNamespace("MAPI");
            mailNamespace.Logon(mail_username, mail_password, false, true);
            return MailNamespace.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderInbox);
        }

A quick, clean approach using very little JS and CSS padding: http://jsfiddle.net/benjamincharity/ZcTsT/14/

var headerHeight = $('#header').height(),
    footerHeight = $('#footer').height();

$('#content').css({
  'padding-top': headerHeight,
  'padding-bottom': footerHeight
});

1. .vs folder should not be committed.
2. create a file with name ".gitignore" inside the projects git root directory.
3. Add the following line ".vs/" in ".gitignore" file.
4. Now commit your project.

You can use a very nice tool called Stetho by adding this to build.gradle file:

compile 'com.facebook.stetho:stetho:1.4.1'

And initialized it inside your Application or Activity onCreate() method:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Stetho.initializeWithDefaults(this);
    setContentView(R.layout.activity_main);
}

Then you can view the db records in chrome in the address:

chrome://inspect/#devices

For more details you can read my post: How to view easily your db records

You can do something like this:

<html>
<head><title>My Glossary</title></head>
<body style="margin:0px;">
        <div id="top" style="position:fixed;background:white;width:100%;">
            <a href="#A">A</a> |
             <a href="#B">B</a> |
            <a href="#Z">Z</a>
        </div>

        <div id="term-defs" style="padding-top:1em;">
           <dl>
               <span id="A"></span>
               <dt>foo</dt>
               <dd>This is the sound made by a fool</dd>
               <!-- and so on ... ->
           </dl>
        </div>
</body>
</html>

It's the position:fixed that's most important, because it takes the top div from the normal page flow and fixes it at it's pre-determined position. It's also important to use the padding-top:1em because otherwise the term-defs div would start right under the top div. The background and width are there to cover the contents of the term-defs div as they scroll under the top div.

Hope this helps.

Simplest of all solutions:

filtered_df = df[df['name'].notnull()]

Thus, it filters out only rows that doesn't have NaN values in 'name' column.

For multiple columns:

filtered_df = df[df[['name', 'country', 'region']].notnull().all(1)]

def is_prime(x):
    n = 2
    if x < n:
        return False
    else:    
        while n < x:
           print n
            if x % n == 0:
                return False
                break
            n = n + 1
        else:
            return True

I ran into the same problem every time it finds a special character marks it as ??. to solve this, I tried using the encoding: ISO-8859-1

BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream("txtPath"),"ISO-8859-1"));

while ((line = br.readLine()) != null) {

}

I hope this can help anyone who sees this post.

Not Found Exceptions

Sometimes you may wish to throw an exception if a model is not found. This is particularly useful in routes or controllers. The findOrFail and firstOrFail methods will retrieve the first result of the query. However, if no result is found, a Illuminate\Database\Eloquent\ModelNotFoundException will be thrown:

$model = App\Flight::findOrFail(1);

$model = App\Flight::where('legs', '>', 100)->firstOrFail();

If the exception is not caught, a 404 HTTP response is automatically sent back to the user. It is not necessary to write explicit checks to return 404 responses when using these methods:

Route::get('/api/flights/{id}', function ($id) {
    return App\Flight::findOrFail($id);
});

1.)You have to make the primary key unique, then you should be able to edit.

right click on you table in the "blue" schemas ->ALTER TABLE, look for your primert key (PK), then just check the check-box, UN, the AI should already be checked. After that just apply and you should be able to edit the table data.

2.)You also need to include the primery key I your select statement

Nr 1 is not really necessary, but a good practice.

One way is to add your shortcut keys to the commands themselves them as InputGestures. Commands are implemented as RoutedCommands.

This enables the shortcut keys to work even if they're not hooked up to any controls. And since menu items understand keyboard gestures, they'll automatically display your shortcut key in the menu items text, if you hook that command up to your menu item.

1. Create static attribute to hold a command (preferably as a property in a static class you create for commands - but for a simple example, just using a static attribute in window.cs):

    public static RoutedCommand MyCommand = new RoutedCommand();
   

2. Add the shortcut key(s) that should invoke method:

    MyCommand.InputGestures.Add(new KeyGesture(Key.S, ModifierKeys.Control));
   

3. Create a command binding that points to your method to call on execute. Put these in the command bindings for the UI element under which it should work for (e.g., the window) and the method:

    <Window.CommandBindings>
        <CommandBinding Command="{x:Static local:MyWindow.MyCommand}" Executed="MyCommandExecuted"/>
    </Window.CommandBindings>
   
    private void MyCommandExecuted(object sender, ExecutedRoutedEventArgs e) { ... }
   

You should have enough space for array1 array and use something like strcat to contact array1 to array2:

char array1[BIG_ENOUGH];
char array2[X];
/* ......             */
/* check array bounds */
/* ......             */

strcat(array1, array2);

Private Sub Workbook_SheetChange(ByVal Sh As Object, ByVal Target As Range)

If Not Intersect(Target, Range("C6:ZZ6")) Is Nothing Then

    If InStr(UCase(Target.Value), "TOTAL") > 0 Then
        Target.Offset(1, 0) = "-"
    End If

End If

End Sub

This will allow you to add columns dynamically and automatically insert a dash underneath any columns in the C row after 6 containing case insensitive "Total". Note: If you go past ZZ6, you will need to change the code, but this should get you where you need to go.

When adding support for mimetype (as suggested by @ProVega) then it is also best practice to remove the type before adding it - this is to prevent unexpected errors when deploying to servers where support for the type already exists, for example:

<staticContent>
    <remove fileExtension=".json" />
    <mimeMap fileExtension=".json" mimeType="application/json" />
</staticContent>

another simplify version

lastBusDay = datetime.datetime.today()
wk_day = datetime.date.weekday(lastBusDay)
if wk_day > 4:      #if it's Saturday or Sunday
    lastBusDay = lastBusDay - datetime.timedelta(days = wk_day-4) #then make it Friday

From official documentation :

To enable Google to crawl your app content and allow users to enter your app from search results, you must add intent filters for the relevant activities in your app manifest. These intent filters allow deep linking to the content in any of your activities. For example, the user might click on a deep link to view a page within a shopping app that describes a product offering that the user is searching for.

Using this link Enabling Deep Links for App Content you'll see how to use it.

And using this Test Your App Indexing Implementation how to test it.

The following XML snippet shows how you might specify an intent filter in your manifest for deep linking.

<activity
    android:name="com.example.android.GizmosActivity"
    android:label="@string/title_gizmos" >
    <intent-filter android:label="@string/filter_title_viewgizmos">
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />
        <!-- Accepts URIs that begin with "http://www.example.com/gizmos” -->
        <data android:scheme="http"
              android:host="www.example.com"
              android:pathPrefix="/gizmos" />
        <!-- note that the leading "/" is required for pathPrefix-->
        <!-- Accepts URIs that begin with "example://gizmos” -->
        <data android:scheme="example"
              android:host="gizmos" />

    </intent-filter>
</activity>

To test via Android Debug Bridge

$ adb shell am start
        -W -a android.intent.action.VIEW
        -d <URI> <PACKAGE>

$ adb shell am start
        -W -a android.intent.action.VIEW
        -d "example://gizmos" com.example.android

This may not be the best way but it definitely makes sure that exception is not thrown from the code block that is being tested.

import org.junit.Test;

I use the following SQL Server Management Objects code to get a list of databases that aren't system databases and aren't snapshots.

using Microsoft.SqlServer.Management.Smo;

public static string[] GetDatabaseNames( string serverName )
{
   var server = new Server( serverName );
   return ( from Database database in server.Databases 
            where !database.IsSystemObject && !database.IsDatabaseSnapshot
            select database.Name 
          ).ToArray();
}

In case anyone's wondering why Eclipse still puts a J2SE-1.5 library on the Java Build Path in a Maven project even if a Java version >= 9 is specified by the maven.compiler.release property (as of October 2020, that is Eclipse version 2020-09 including Maven version 3.6.3): Maven by default uses version 3.1 of the Maven compiler plugin, while the release property has been introduced only in version 3.6.

So don't forget to include a current version of the Maven compiler plugin in your pom.xml when using the release property:

<properties>
    <maven.compiler.release>15</maven.compiler.release>
</properties>

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.8.1</version>
        </plugin>
    </plugins>
</build>

Or alternatively but possibly less prominent, specify the Java version directly in the plugin configuration:

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.8.1</version>
            <configuration>
                <release>15</release>
            </configuration>
        </plugin>
    </plugins>
</build>

This picks up Line's comment on the accepted answer which, had I seen it earlier, would have saved me another hour of searching.

Example of AbstractMap.SimpleEntry:

import java.util.Map; 
import java.util.AbstractMap;
import java.util.AbstractMap.SimpleEntry;

Instantiate:

ArrayList<Map.Entry<Integer, Integer>> arr = 
    new ArrayList<Map.Entry<Integer, Integer>>();

Add rows:

arr.add(new AbstractMap.SimpleEntry(2, 3));
arr.add(new AbstractMap.SimpleEntry(20, 30));
arr.add(new AbstractMap.SimpleEntry(2, 4));

Fetch rows:

System.out.println(arr.get(0).getKey());
System.out.println(arr.get(0).getValue());
System.out.println(arr.get(1).getKey());
System.out.println(arr.get(1).getValue());
System.out.println(arr.get(2).getKey());
System.out.println(arr.get(2).getValue());

Should print:

2
3
20
30
2
4

It's good for defining edges of graph structures. Like the ones between neurons in your head.

The JSON format can contain only those types of value:

• string
• number
• object
• array
• true
• false
• null

An image is of the type "binary" which is none of those. So you can't directly insert an image into JSON. What you can do is convert the image to a textual representation which can then be used as a normal string.

The most common way to achieve that is with what's called base64. Basically, instead of encoding it as 1 and 0s, it uses a range of 64 characters which makes the textual representation of it more compact. So for example the number '64' in binary is represented as 1000000, while in base64 it's simply one character: =.

There are many ways to encode your image in base64 depending on if you want to do it in the browser or not.

Note that if you're developing a web application, it will be way more efficient to store images separately in binary form, and store paths to those images in your JSON or elsewhere. That also allows your client's browser to cache the images.

$.when doesn't work for me, callback(x) instead of return x worked as described here: https://stackoverflow.com/a/13455253/10357604

In eclipse format xml:

For tab:

<setting id="org.eclipse.jdt.core.formatter.tabulation.char" value="tab"/>

For space:

<setting id="org.eclipse.jdt.core.formatter.tabulation.char" value="space"/>

Why its printing 0,1,2...?

Because those are indexes of the items in array, and index always starts from 0 to array.length-1.

To print the item count instead of index, use index+1. Like this:

<li v-for="(catalog, index) in catalogs">this index : {{index + 1}}</li>

And to show the total count use array.length, Like this:

<p>Total Count: {{ catalogs.length }}</p>

As per DOC:

v-for also supports an optional second argument (not first) for the index of the current item.

This error message happens either because your ProfileDto class is not registered in the JAXB Content, or the class using it does not use @XmlSeeAlso(ProfileDto.class) to make processable by JAXB.

About your comment:

I was under the impression the annotations was only needed when the referenced class was a sub-class.

No, they are also needed when not declared in the JAXB context or, for example, when the only class having a static reference to it has this reference annotated with @XmlTransient. I maintain a tutorial here.

Try mylist[0][0]. This should return the first character.

You can use 'USING' instead of 'ON' as in the query

SELECT * FROM table1 LEFT JOIN table2 USING (id);

U can also use PoDoFo library. The main goal is that it published under LGPL. Since it is written in C++ you should cross-compile it using NDK and write C-side and Java wrapper. Some of third-party libraries can be used from OpenCV project. Also in OpenCV project U can find android.toolchain.cmake file, which will help you with generating Makefile.

I think the Apache Commons Lang library's StringEscapeUtils.unescapeHtml3() and unescapeHtml4() methods are what you are looking for. See https://commons.apache.org/proper/commons-text/javadocs/api-release/org/apache/commons/text/StringEscapeUtils.html.

In my Notepad++ 7.2.2, the Preferences section it's a bit different.

2. Choose Adaptive.sublime-theme

Previously posted solutions did not work for me. cell.getRawValue() returned the same formula as stated in the cell. The following function worked for me:

    Sheet sheet = wb.getSheetAt(0);
    FormulaEvaluator evaluator = wb.getCreationHelper().createFormulaEvaluator();

    CellReference cellReference = new CellReference("C2"); // pass the cell which contains the formula
    Row row = sheet.getRow(cellReference.getRow());
    Cell cell = row.getCell(cellReference.getCol());

    CellValue cellValue = evaluator.evaluate(cell);

I don't think the existing answers adequately addressed this part of the question:

When should I use them?

If you're writing an API that will be published or reused within your organization, you should write comprehensive Javadoc comments for every public class, method, and field, as well as protected methods and fields of non-final classes. Javadoc should cover everything that cannot be conveyed by the method signature, such as preconditions, postconditions, valid arguments, runtime exceptions, internal calls, etc.

If you're writing an internal API (one that's used by different parts of the same program), Javadoc is arguably less important. But for the benefit of maintenance programmers, you should still write Javadoc for any method or field where the correct usage or meaning is not immediately obvious.

The "killer feature" of Javadoc is that it's closely integrated with Eclipse and other IDEs. A developer only needs to hover their mouse pointer over an identifier to learn everything they need to know about it. Constantly referring to the documentation becomes second nature for experienced Java developers, which improves the quality of their own code. If your API isn't documented with Javadoc, experienced developers will not want to use it.

I think the XML format can be so diverse that it's impossible to write a code that could do this without a very strict defined XML format. Here is what I mean:

<persons>
    <person>
        <name>Koen Bok</name>
        <age>26</age>
    </person>
    <person>
        <name>Plutor Heidepeen</name>
        <age>33</age>
    </person>
</persons>

Would become

{'persons': [
    {'name': 'Koen Bok', 'age': 26},
    {'name': 'Plutor Heidepeen', 'age': 33}]
}

But what would this be:

<persons>
    <person name="Koen Bok">
        <locations name="defaults">
            <location long=123 lat=384 />
        </locations>
    </person>
</persons>

See what I mean?

public void schedule(TimerTask task,long delay)

Schedules the specified task for execution after the specified delay.

you want:

public void schedule(TimerTask task, long delay, long period)

Schedules the specified task for repeated fixed-delay execution, beginning after the specified delay. Subsequent executions take place at approximately regular intervals separated by the specified period.

Coming at this almost a year later, there's a different manner in which I solved my particular problem. Since I wanted the link to be handled by my own app, there is a solution that is a bit simpler.

Besides the default intent filter, I simply let my target activity listen to ACTION_VIEW intents, and specifically, those with the scheme com.package.name

<intent-filter>
    <category android:name="android.intent.category.DEFAULT" />
    <action android:name="android.intent.action.VIEW" />
    <data android:scheme="com.package.name" />  
</intent-filter>

This means that links starting with com.package.name:// will be handled by my activity.

So all I have to do is construct a URL that contains the information I want to convey:

com.package.name://action-to-perform/id-that-might-be-needed/

In my target activity, I can retrieve this address:

Uri data = getIntent().getData();

In my example, I could simply check data for null values, because when ever it isn't null, I'll know it was invoked by means of such a link. From there, I extract the instructions I need from the url to be able to display the appropriate data.

Serializable

Serializable is a markable interface or we can call as an empty interface. It doesn’t have any pre-implemented methods. Serializable is going to convert an object to byte stream. So the user can pass the data between one activity to another activity. The main advantage of serializable is the creation and passing data is very easy but it is a slow process compare to parcelable.

Parcelable

Parcel able is faster than serializable. Parcel able is going to convert object to byte stream and pass the data between two activities. Writing parcel able code is little bit complex compare to serialization. It doesn’t create more temp objects while passing the data between two activities.

You can read multiple inputs in Python 3.x by using below code which splits input string and converts into the integer and values are printed

user_input = input("Enter Numbers\n").split(',')
#strip is used to remove the white space. Not mandatory
all_numbers = [int(x.strip()) for x in user_input]
for i in all_numbers:
    print(i)

Your sprite is created mid way through the playerSprite function... it also goes out of scope and ceases to exist at the end of that same function. The sprite must be created where you can pass it to playerSprite to initialize it and also where you can pass it to your draw function.

Perhaps declare it above your first while?

I won't address the READ UNCOMMITTED argument, just your original question.

Yes, you need WITH(NOLOCK) on each table of the join. No, your queries are not the same.

Try this exercise. Begin a transaction and insert a row into table1 and table2. Don't commit or rollback the transaction yet. At this point your first query will return successfully and include the uncommitted rows; your second query won't return because table2 doesn't have the WITH(NOLOCK) hint on it.

The problem is the import of ProjectsListComponent in your ProjectsModule. You should not import that, but add it to the export array, if you want to use it outside of your ProjectsModule.

Other issues are your project routes. You should add these to an exportable variable, otherwise it's not AOT compatible. And you should -never- import the BrowserModule anywhere else but in your AppModule. Use the CommonModule to get access to the *ngIf, *ngFor...etc directives:

@NgModule({
  declarations: [
     ProjectsListComponent
  ],
  imports: [
    CommonModule,
    RouterModule.forChild(ProjectRoutes)
  ],
  exports: [
     ProjectsListComponent
  ]
})

export class ProjectsModule {}

project.routes.ts

export const ProjectRoutes: Routes = [
      { path: 'projects', component: ProjectsListComponent }
]

JPEG can't support transparency because it uses RGB color space. If you want transparency use a format that supports alpha values. Example PNG is an image format that uses RGBA color space where (r = red, g = green, b = blue, a = alpha value). Alpha value is used as an opacity measure, 0% is fully transparent and 100% is completely opaque. pixel.

Another option using git binaries:

1. Install git: http://git-scm.com/download/win
2. Start Menu > cmd (shift+enter to go as Administrator)
3. set PATH=%PATH%;C:\Program Files\Git\usr\bin
4. vagrant ssh

Hope this helps :)

Just a bonus after months using that on Windows: use Console instead of the Win terminal, so you can always open a new terminal tab with PATH set (configure it on options)

I just successfully installed a package for excel. After installing the python 3.6, you have to download the desired package, then install. For eg,

1. python.exe -m pip download openpyxl==2.1.4

2. python.exe -m pip install openpyxl==2.1.4

You need to install VMware Tools on your vm:

To install VMware Tools in most VMware products:

Power on the virtual machine.

Log in to the virtual machine using an account with Administrator or root privileges.

Wait for the desktop to load and be ready.

Click Install/Upgrade VMware Tools. There are two places to find this option:

• Right-click on the running virtual machine object and choose Install/Upgrade VMware Tools.

• Right-click on the running virtual machine object and click Open Console. In the Console menu click VM and click Install/Upgrade VMware Tools.

  Note: In ESX/ESXi 4.x, navigate to VM > Guest > Install/Upgrade VMware Tools. In Workstation, navigate to VM > Install/Upgrade VMware Tools.

You can use the cache dir using context.getCacheDir().

File temp=File.createTempFile("prefix","suffix",context.getCacheDir());

spark.default.parallelism is the default number of partition set by spark which is by default 200. and if you want to increase the number of partition than you can apply the property spark.sql.shuffle.partitions to set number of partition in the spark configuration or while running spark SQL.

Normally this spark.sql.shuffle.partitions it is being used when we have a memory congestion and we see below error: spark error:java.lang.IllegalArgumentException: Size exceeds Integer.MAX_VALUE

so set your can allocate a partition as 256 MB per partition and that you can use to set for your processes.

also If number of partitions is near to 2000 then increase it to more than 2000. As spark applies different logic for partition < 2000 and > 2000 which will increase your code performance by decreasing the memory footprint as data default is highly compressed if >2000.

If it's been moved you can also (in IE 11, and I'm pretty sure this translates back to at least 10):

• Tools - Internet Options
• Under Browsing history click Settings
• Under Current location it shows the directory name

Note: The View files button will open a Windows Explorer window there.

For example, mine shows C:\BrowserCache\IE\Temporary Internet Files

wrote these some time back, found it very useful for a wide range of applications.

Had a similar problem with the GitHub because I was using HTTPS protocol. To check what protocol you're using just run

git config -l

and look at the line starting with remote.origin.url. To switch your protocol

git config remote.origin.url [email protected]:your_username/your_project.git

IF(compliment IN('set','Y',1), 'Y', 'N') AS customer_compliment

Will do the job as Buttle Butkus suggested.

You can change your second condition to check only the span element:

...and contains(div/span, 'someText')]

If the span isn't always inside another div you can also use

...and contains(.//span, 'someText')]

This searches for the span anywhere inside the div.

The $innerListItem.position().top is actually relative to the .scrollTop() of its first positioned ancestor. So the way to calculate the correct $parentDiv.scrollTop() value is to begin by making sure that $parentDiv is positioned. If it doesn't already have an explicit position, use position: relative. The elements $innerListItem and all its ancestors up to $parentDiv need to have no explicit position. Now you can scroll to the $innerListItem with:

// Scroll to the top
$parentDiv.scrollTop($parentDiv.scrollTop() + $innerListItem.position().top);

// Scroll to the center
$parentDiv.scrollTop($parentDiv.scrollTop() + $innerListItem.position().top
    - $parentDiv.height()/2 + $innerListItem.height()/2);

The problem for me was not got the port from process.env.PORT it is very important because Heroku and other services properly do a random port numbers to use.

So that is the code that work for me eventuly :

var app = require('express')();
var http = require('http').createServer(app);
const serverPort = process.env.PORT ; //<----- important 

const io = require('socket.io')(http,{
  cors: {
    origin: '*',
    methods: 'GET,PUT,POST,DELETE,OPTIONS'.split(','),
    credentials: true
  }
});

http.listen(serverPort,()=>{
  console.log(`server listening on port ${serverPort}`)
})

You need to target the device by its User Agent, using some script. The user agent for the iPad is:

Mozilla/5.0 (iPad; U; CPU OS 3_2 like Mac OS X; en-us) AppleWebKit/531.21.10 (KHTML, like Gecko) Version/4.0.4 Mobile/7B334b Safari/531.21.10

Just in case you forgot or avoided to copy through PHPMYADMIN export feature..

Procedure: You can manually copy: Procedure For MAC OS, for latest versions of XAMPP

Location : Find the database folders here /Users/XXXXUSER/XAMPP/xamppfiles/var/mysql..

Solution: Copy the entire folder with database names into your new xampp in similar folder.

Hope it helps, happy coding.

Let's go to the source -- 2.6.32, for example. The message is printed by show_signal_msg() function in arch/x86/mm/fault.c if the show_unhandled_signals sysctl is set.

"error" is not an errno nor a signal number, it's a "page fault error code" -- see definition of enum x86_pf_error_code.

"[7fa44d2f8000+f6f000]" is starting address and size of virtual memory area where offending object was mapped at the time of crash. Value of "ip" should fit in this region. With this info in hand, it should be easy to find offending code in gdb.

Actually, it is quite easy to write sufficiently clean and compact code with DI (I wonder, will it be/stay pythonic then, but anyway :) ), for example I actually perefer this way of coding:

def polite(name_str):
    return "dear " + name_str

def rude(name_str):
    return name_str + ", you, moron"

def greet(name_str, call=polite):
    print "Hello, " + call(name_str) + "!"

_

>>greet("Peter")
Hello, dear Peter!
>>greet("Jack", rude)
Hello, Jack, you, moron!

Yes, this can be viewed as just a simple form of parameterizing functions/classes, but it does its work. So, maybe Python's default-included batteries are enough here too.

P.S. I have also posted a larger example of this naive approach at Dynamically evaluating simple boolean logic in Python.

If you have merged cells,

Sub OneCell()
    Sheets("Sheet2").range("B1:B3").value = Sheets("Sheet1").range("A1:A3").value
End Sub

that doesn't copy cells as they are, where previous code does copy exactly as they look like (merged).

Try simply to reset last commit using --soft flag

git reset --soft HEAD~1

Note :

For Windows, wrap the HEAD parts in quotes like git reset --soft "HEAD~1"

I am using Laravel 5.4 and unfortunately although the accepted answer seems fine, for preflighted requests (like PUT and DELETE) which will be preceded by an OPTIONS request, specifying the middleware in the $routeMiddleware array (and using that in the routes definition file) will not work unless you define a route handler for OPTIONS as well. This is because without an OPTIONS route Laravel will internally respond to that method without the CORS headers.

So in short either define the middleware in the $middleware array which runs globally for all requests or if you're doing it in $middlewareGroups or $routeMiddleware then also define a route handler for OPTIONS. This can be done like this:

Route::match(['options', 'put'], '/route', function () {
    // This will work with the middleware shown in the accepted answer
})->middleware('cors');

I also wrote a middleware for the same purpose which looks similar but is larger in size as it tries to be more configurable and handles a bunch of conditions as well:

<?php

namespace App\Http\Middleware;

use Closure;

      {
        return $next($request);
      }

      static::$allowedOrigin = $this->resolveAllowedOrigin($request);

      static::$allowedHeaders = $this->resolveAllowedHeaders($request);

      $headers = [

        'Access-Control-Allow-Credentials'  => static::$allowCredentials,
      ];

      // For preflighted requests
      if ($request->getMethod() === 'OPTIONS')
      {
        return response('', 200)->withHeaders($headers);
      }

      $response = $next($request)->withHeaders($headers);

      return $response;
    }

    /**
     * Incoming request is a CORS request if the Origin
     * header is set and Origin !== Host

     */
    private function isCorsRequest($request)
    {
      $requestHasOrigin = $request->headers->has('Origin');

      if ($requestHasOrigin)
      {
        $origin = $request->headers->get('Origin');

        $host = $request->getSchemeAndHttpHost();

        {

      }

      return false;
    }

    /**

     * only if it is present in the whitelist.
     *
     * @param  \Illuminate\Http\Request  $request
     */
    private function resolveAllowedOrigin($request)
    {
      $allowedOrigin = static::$allowedOrigin;

      // If origin is in our $allowedOriginsWhitelist
      // then we send that in Access-Control-Allow-Origin

      $origin = $request->headers->get('Origin');

      if (in_array($origin, static::$allowedOriginsWhitelist))
      {
        $allowedOrigin = $origin;
      }

      return $allowedOrigin;

}

Decode them and compare them as mgilson comment.

Order does not matter for dictionary as long as the keys, and values matches. (Dictionary has no order in Python)

>>> {'a': 1, 'b': 2} == {'b': 2, 'a': 1}
True

But order is important in list; sorting will solve the problem for the lists.

>>> [1, 2] == [2, 1]
False
>>> [1, 2] == sorted([2, 1])
True

>>> a = '{"errors": [{"error": "invalid", "field": "email"}, {"error": "required", "field": "name"}], "success": false}'
>>> b = '{"errors": [{"error": "required", "field": "name"}, {"error": "invalid", "field": "email"}], "success": false}'
>>> a, b = json.loads(a), json.loads(b)
>>> a['errors'].sort()
>>> b['errors'].sort()
>>> a == b
True

Above example will work for the JSON in the question. For general solution, see Zero Piraeus's answer.

You can easily import your model and run this:

from models import User

# User is the name of table that has a column name
users = User.query.all()

for user in users:
    print user.name

This works for me. in place of customTheme you can put you theme in styles. in this code you can also change the font and text size.

    <style name="MyTheme.NavMenu" parent="CustomTheme">
            <item name="android:textSize">16sp</item>
            <item name="android:fontFamily">@font/ssp_semi_bold</item>
            <item name="android:textColorPrimary">@color/yourcolor</item>
        </style>

here is my navigation view

<android.support.design.widget.NavigationView
        android:id="@+id/navigation_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        app:theme="@style/MyTheme.NavMenu"
        app:headerLayout="@layout/nav_header_main"
        app:menu="@menu/activity_main_drawer">

        <include layout="@layout/layout_update_available"/>

    </android.support.design.widget.NavigationView>

In modern browsers that support HTML5, the following is possible:

<a href="link/to/your/download/file" download>Download link</a>

You also can use this:

<a href="link/to/your/download/file" download="filename">Download link</a>

This will allow you to change the name of the file actually being downloaded.

Adding in example for solution given earlier. By using socket.io-client https://github.com/socketio/socket.io-client

Client Side:

//client.js
var io = require('socket.io-client');
var socket = io.connect('http://localhost:3000', {reconnect: true});

// Add a connect listener
socket.on('connect', function (socket) {
    console.log('Connected!');
});
socket.emit('CH01', 'me', 'test msg');

Server Side :

//server.js
var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io')(http);

io.on('connection', function (socket){
   console.log('connection');

  socket.on('CH01', function (from, msg) {
    console.log('MSG', from, ' saying ', msg);
  });

});

http.listen(3000, function () {
  console.log('listening on *:3000');
});

Run :

Open 2 console and run node server.js and node client.js

try as this code.

$.ajax({
        type: "POST",
        url: "http://rt.ja.com/includes/register.php?submit=1",
        data: "username="+username+"&email="+email+"&password="+password+"&passconf="+passconf,

        success: function(html)
        {   
            //alert(html);
            $('#userError').html(html);
            $("#userError").html(userChar);
            $("#userError").html(userTaken);
        }
    });

i think this will work definitely..

you can also use .serialize() function for sending data via jquery Ajax..

i.e: data : $("#registerSubmit").serialize()

Thanks.

Please write following code in menu.xml file:

<menu xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:my_menu_tutorial_app="http://schemas.android.com/apk/res-auto"
      xmlns:tools="http://schemas.android.com/tools"
      tools:context="com.example.mymenus.menu_app.MainActivity">
<item android:id="@+id/item_one"
      android:icon="@drawable/menu_icon"
      android:orderInCategory="l01"
      android:title="Item One"
      my_menu_tutorial_app:showAsAction="always">
      <!--sub-menu-->
      <menu>
          <item android:id="@+id/sub_one"
                android:title="Sub-menu item one" />
          <item android:id="@+id/sub_two"
                android:title="Sub-menu item two" />
      </menu>

Also write this java code in activity class file:

public boolean onOptionsItemSelected(MenuItem item)
{
    super.onOptionsItemSelected(item);
    Toast.makeText(this, "Menus item selected: " +
        item.getTitle(), Toast.LENGTH_SHORT).show();
    switch (item.getItemId())
    {
        case R.id.sub_one:
            isItemOneSelected = true;
            supportInvalidateOptionsMenu();
            return true;
        case MENU_ITEM + 1:
            isRemoveItem = true;
            supportInvalidateOptionsMenu();
            return true;
        default:
            return false;
    }
}

This is the easiest way to display menus in action bar.

Generally git pull is enough, but I'm not sure what layout you have chosen (or has github chosen for you).

To reset the IDs of my User table, I use the following SQL query. It's been said above that this will ruin any relationships you may have with any other tables.

ALTER TABLE `users` DROP `id`;
ALTER TABLE `users` AUTO_INCREMENT = 1;
ALTER TABLE `users` ADD `id` int UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY FIRST;

public ResponseEntity<?> ApiCall(@PathVariable(name = "id") long id) {
    JSONObject resp = new JSONObject();
    resp.put("status", 0);
    resp.put("id", id);

    return new ResponseEntity<String>(resp.toString(), HttpStatus.CREATED);
}

I use .NetCore for my back-end tasks,I was able to resolve this issue by using the Newtonsoft.Json library package to return a JSON string from my controller.

Apparently, not all JSON Serializers are built to the right specifications..NET 5's "return Ok("");" was definitely not sufficient.

In Swift 3 here's how you do it to the UIImage itself:

let size = CGSize(width: image.size.width, height: image.size.height)
UIGraphicsBeginImageContext(size)
let rect = CGRect(x: 0, y: 0, width: size.width, height: size.height)
image?.draw(in: rect, blendMode: .normal, alpha: 1.0)
let context = UIGraphicsGetCurrentContext()
context?.setStrokeColor(red: 0, green: 0, blue: 0, alpha: 1)
context?.stroke(rect)
let newImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()

self.imageView.image = newImage

Someone pointed me to this thread because I had this same issue but it didn't work for me. After hours of searching I found a solution using this - https://github.com/rewish/jquery-bgswitcher#readme

It has a few other options other than fade too.

I use a Dictionary and because of the repetetiveness and possible missing keys, I quickly patched together a small method:

 private static string GetKey(IReadOnlyDictionary<string, string> dictValues, string keyValue)
 {
     return dictValues.ContainsKey(keyValue) ? dictValues[keyValue] : "";
 }

Calling it:

var entry = GetKey(dictList,"KeyValue1");

Gets the job done.

MySQL doesn't care what IP its on. Closest you could get would be hostname:

select * from GLOBAL_variables where variable_name like 'hostname';

The class Doctrine\ORM\EntityRepository implements Doctrine\Common\Collections\Selectable API.

The Selectable interface is very flexible and quite new, but it will allow you to handle comparisons and more complex criteria easily on both repositories and single collections of items, regardless if in ORM or ODM or completely separate problems.

This would be a comparison criteria as you just requested as in Doctrine ORM 2.3.2:

$criteria = new \Doctrine\Common\Collections\Criteria();
$criteria->where($criteria->expr()->gt('prize', 200));

$result = $entityRepository->matching($criteria);

The major advantage in this API is that you are implementing some sort of strategy pattern here, and it works with repositories, collections, lazy collections and everywhere the Selectable API is implemented.

This allows you to get rid of dozens of special methods you wrote for your repositories (like findOneBySomethingWithParticularRule), and instead focus on writing your own criteria classes, each representing one of these particular filters.

Use the stringi package:

require(stringi)

group<-data.frame(c("12357e", "12575e", "197e18", "e18947"))
stri_replace_all(group[,1], "", fixed="e")
[1] "12357" "12575" "19718" "18947"

The solution that work for me in windows 64bits is the following

git config --system http.sslverify false

svn copy http://URL/svn/trukSource http://URL/svn/tagDestination -m "Test tag code" 
  $error[0].Exception | Select-object Data

All you have to do change URL path. This command will create new dir "tagDestination". The second line will be let know you the full error details if any occur. Create svn env variable if not created. Can check (Cmd:- set, Powershell:- Get-ChildItem Env:) Default path is "C:\Program Files\TortoiseSVN\bin\TortoiseProc.exe"

ALTER TABLE table_name DROP PRIMARY KEY,ADD PRIMARY KEY (col_name1, col_name2);

Use binary search algorithm to improve the performace when the node has large quantity siblings.

function getChildrenIndex(ele){
    //IE use Element.sourceIndex
    if(ele.sourceIndex){
        var eles = ele.parentNode.children;
        var low = 0, high = eles.length-1, mid = 0;
        var esi = ele.sourceIndex, nsi;
        //use binary search algorithm
        while (low <= high) {
            mid = (low + high) >> 1;
            nsi = eles[mid].sourceIndex;
            if (nsi > esi) {
                high = mid - 1;
            } else if (nsi < esi) {
                low = mid + 1;
            } else {
                return mid;
            }
        }
    }
    //other browsers
    var i=0;
    while(ele = ele.previousElementSibling){
        i++;
    }
    return i;
}

If you use an operating system that uses copy-on-write fork() semantics (like any common unix), then as long as you never alter your data structure it will be available to all child processes without taking up additional memory. You will not have to do anything special (except make absolutely sure you don't alter the object).

The most efficient thing you can do for your problem would be to pack your array into an efficient array structure (using numpy or array), place that in shared memory, wrap it with multiprocessing.Array, and pass that to your functions. This answer shows how to do that.

If you want a writeable shared object, then you will need to wrap it with some kind of synchronization or locking. multiprocessing provides two methods of doing this: one using shared memory (suitable for simple values, arrays, or ctypes) or a Manager proxy, where one process holds the memory and a manager arbitrates access to it from other processes (even over a network).

The Manager approach can be used with arbitrary Python objects, but will be slower than the equivalent using shared memory because the objects need to be serialized/deserialized and sent between processes.

There are a wealth of parallel processing libraries and approaches available in Python. multiprocessing is an excellent and well rounded library, but if you have special needs perhaps one of the other approaches may be better.

Using canvas to display Videos

Displaying a video is much the same as displaying an image. The minor differences are to do with onload events and the fact that you need to render the video every frame or you will only see one frame not the animated frames.

The demo below has some minor differences to the example. A mute function (under the video click mute/sound on to toggle sound) and some error checking to catch IE9+ and Edge if they don't have the correct drivers.

The previous answers by user372551 is out of date (December 2010) and has a flaw in the rendering technique used. It uses the setTimeout and a rate of 33.333..ms which setTimeout will round down to 33ms this will cause the frames to be dropped every two seconds and may drop many more if the video frame rate is any higher than 30. Using setTimeout will also introduce video shearing created because setTimeout can not be synced to the display hardware.

There is currently no reliable method that can determine a videos frame rate unless you know the video frame rate in advance you should display it at the maximum display refresh rate possible on browsers. 60fps

The given top answer was for the time (6 years ago) the best solution as requestAnimationFrame was not widely supported (if at all) but requestAnimationFrame is now standard across the Major browsers and should be used instead of setTimeout to reduce or remove dropped frames, and to prevent shearing.

The example demo.

Loads a video and set it to loop. The video will not play until the you click on it. Clicking again will pause. There is a mute/sound on button under the video. The video is muted by default.

Note users of IE9+ and Edge. You may not be able to play the video format WebM as it needs additional drivers to play the videos. They can be found at tools.google.com Download IE9+ WebM support

Canvas extras

Using the canvas to render video gives you additional options in regard to displaying and mixing in fx. The following image shows some of the FX you can get using the canvas. Using the 2D API gives a huge range of creative possibilities.

I know, this is an old question, but couldn't find the solution here. After some tries, I found out, that some added "<asp:UpdatePanel" had been the reason.

After (re)moving them, all works fine like before.

I think this is the syntax you are looking for:

if [ -z != $errorstatus ] 
then
commands
else
commands
fi

If you do not want to configure the message converters yourself, you can use either @EnableWebMvc or <mvc:annotation-driven />, add Jackson to the classpath and Spring will give you both JSON, XML (and a few other converters) by default. Additionally, you will get some other commonly used features for conversion, formatting and validation.

Try something like this

String filePath = new File("").getAbsolutePath();
filePath.concat("path to the property file");

So your new file points to the path where it is created, usually your project home folder.

[EDIT]

As @cmc said,

    String basePath = new File("").getAbsolutePath();
    System.out.println(basePath);

    String path = new File("src/main/resources/conf.properties")
                                                           .getAbsolutePath();
    System.out.println(path);

Both give the same value.

void Test(){
    var obj = new{a="aaa", b="bbb"};

    var val_a = obj.GetValObjDy("a"); //="aaa"
    var val_b = obj.GetValObjDy("b"); //="bbb"
}
//create in a static class

{            
     return obj.GetType().GetProperty(propertyName).GetValue(obj, null);

        for (int i = 0; i < position; i++) {
            d = DateHelper.getTomorrow(d);

I don't there there is any DataSource for the gridview
Though you have DataBind in your code as

gvdetails.DataBind(); 

I found this post while looking at this other SO post. Below is a copy of the answer I gave there.

I know this is an old thread, but React has become popular and, perhaps, someone using React will come here looking for an answer to the same problem.

So, if you are using React, you can do something like the below, which was an answer original provided by Ben Alpert of the React team here

getInitialState: function(event) {
    return {image: "http://example.com/primary_image.jpg"};
},
handleError: function(event) {
    this.setState({image: "http://example.com/failover_image.jpg"});
},
render: function() {
    return (
        <img onError={this.handleError} src={src} />;
    );
}

string result = "i am '[email protected]'"; // string

int in1 = result.IndexOf('\''); // get the index of first quote

int in2 = result.IndexOf('\'', in1 + 1); // get the index of second

string quoted_text = result.Substring(in1 + 1, in2 - in1); // get the string between quotes

How can I roll back my previous 4 commits locally in a branch?

Which means, you are not creating new branch and going into detached state. New way of doing that is:

git switch --detach revison

Mutations expect two arguments: state and payload, where the current state of the store is passed by Vuex itself as the first argument and the second argument holds any parameters you need to pass.

The easiest way to pass a number of parameters is to destruct them:

mutations: {
    authenticate(state, { token, expiration }) {
        localStorage.setItem('token', token);
        localStorage.setItem('expiration', expiration);
    }
}

Then later on in your actions you can simply

store.commit('authenticate', {
    token,
    expiration,
});

Almost certainly more efficient than using Strings:

int firstDigit(int x) {
    while (x > 9) {
        x /= 10;
    }
    return x;
}

(Works only for nonnegative integers.)

Chr(10) is the Line Feed character and Chr(13) is the Carriage Return character.

You probably won't notice a difference if you use only one or the other, but you might find yourself in a situation where the output doesn't show properly with only one or the other. So it's safer to include both.

Historically, Line Feed would move down a line but not return to column 1:

This  
    is  
        a  
            test.

Similarly Carriage Return would return to column 1 but not move down a line:

This  
is  
a  
test.

Paste this into a text editor and then choose to "show all characters", and you'll see both characters present at the end of each line. Better safe than sorry.

Maybe the string keyword confused you, as it looks exactly like any other value type declaration, but it is actually an alias to System.String as explained in this question.
Also the dark blue color in Visual Studio and the lowercase first letter may mislead into thinking it is a struct.

For Unicode support:

public class HexadecimalEncoding
{
    public static string ToHexString(string str)
    {
        var sb = new StringBuilder();

        var bytes = Encoding.Unicode.GetBytes(str);
        foreach (var t in bytes)
        {
            sb.Append(t.ToString("X2"));
        }

        return sb.ToString(); // returns: "48656C6C6F20776F726C64" for "Hello world"
    }

    public static string FromHexString(string hexString)
    {
        var bytes = new byte[hexString.Length / 2];
        for (var i = 0; i < bytes.Length; i++)
        {
            bytes[i] = Convert.ToByte(hexString.Substring(i * 2, 2), 16);
        }

        return Encoding.Unicode.GetString(bytes); // returns: "Hello world" for "48656C6C6F20776F726C64"
    }
}

Edit: Passing the operator as a reference doesnt work. For simplicity, understand it as a function pointer. You just send the pointer, not a reference. I think you are trying to write something like this.

struct Square
{
    double operator()(double number) { return number * number; }
};

template <class Function>
double integrate(Function f, double a, double b, unsigned int intervals)
{
    double delta = (b - a) / intervals, sum = 0.0;

    while(a < b)
    {
        sum += f(a) * delta;
        a += delta;
    }

    return sum;
}

. .

std::cout << "interval : " << i << tab << tab << "intgeration = "
 << integrate(Square(), 0.0, 1.0, 10) << std::endl;

Try this,

EditText x = (EditText) findViewById(R.id.editText1);
int n = Integer.parseInt(x.getText().toString());

$('#div_id').empty();

or

$('.div_class').empty();

Works Fine to remove contents inside a div

an important thing is to keep the multiselect open all the time. The simplest way is to fire open event on 'conditions' in your code:

<select data-placeholder="Choose a Country..." multiple class="select2-select" id="myList">
    <option value="United States">United States</option>
    <option value="United Kingdom">United Kingdom</option>
    <option value="Afghanistan">Afghanistan</option>
    <option value="Aland Islands">Aland Islands</option>
    <option value="Albania">Albania</option>
    <option value="Algeria">Algeria</option>
</select>

javascript:

$(".select2-select").select2({closeOnSelect:false});
$("#myList").select2("open");

fiddle: http://jsfiddle.net/xpvt214o/153442/

Something like:

>>> bytes.fromhex('4a4b4c').decode('utf-8')
'JKL'

Just put the actual encoding you are using.

The following worked for me:

ForceCursor = true;
Cursor = Cursors.Wait;

The important difference between signed and unsigned ints is the interpretation of the last bit. The last bit in signed types represent the sign of the number, meaning: e.g:

0001 is 1 signed and unsigned 1001 is -1 signed and 9 unsigned

(I avoided the whole complement issue for clarity of explanation! This is not exactly how ints are represented in memory!)

You can imagine that it makes a difference to know if you compare with -1 or with +9. In many cases, programmers are just too lazy to declare counting ints as unsigned (bloating the for loop head f.i.) It is usually not an issue because with ints you have to count to 2^31 until your sign bit bites you. That's why it is only a warning. Because we are too lazy to write 'unsigned' instead of 'int'.

<div> looks nice, but a bit complicated in setting all these display: block, float: left... Maybe because the general idea behind <div> is a block of a paragraph size or more.

I have found the following nice way for spacing:

<button>Button 1></button>
<button style="margin-left: 4em">Button 2</button>

A friend who is a JIRA wiz showed me that you can actually pass the filter (escaped) as a jqlQuery parameter to JIRA via URL:

http://hostname/secure/IssueNavigator!executeAdvanced.jspa?clear=true&runQuery=true&jqlQuery=created%3E='2010-05-31%2000:00'%20AND%20created%3C='2010-06-06%2023:59'%20ORDER%20BY%20created%20ASC

I created an ASP.Net page which generates the URLs based on an offset week or month.

Everybody's happy!

The first part (setting the output size explictly) isn't too hard:

import matplotlib.pyplot as plt
list1 = [3,4,5,6,9,12]
list2 = [8,12,14,15,17,20]
fig = plt.figure(figsize=(4,3))
ax = fig.add_subplot(111)
ax.plot(list1, list2)
fig.savefig('fig1.png', dpi = 300)
fig.close()

But after a quick google search on matplotlib + tiff, I'm not convinced that matplotlib can make tiff plots. There is some mention of the GDK backend being able to do it.

One option would be to convert the output with a tool like imagemagick's convert.

(Another option is to wait around here until a real matplotlib expert shows up and proves me wrong ;-)

struct timeval contains two components, the second and the microsecond. A timestamp with microsecond precision is represented as seconds since the epoch stored in the tv_sec field and the fractional microseconds in tv_usec. Thus you cannot just ignore tv_sec and expect sensible results.

If you use Linux or *BSD, you can use timersub() to subtract two struct timeval values, which might be what you want.

For commenting blocks of code, I like the NERD Commenter plugin.

Select some text:

Shift-V
...select the lines of text you want to comment....

Comment:

,cc

Uncomment:

,cu

Or just toggle the comment state of a line or block:

,c<space>

You can call the stat() function and use the S_ISREG() macro on the st_mode field of the stat structure in order to determine if your path points to a regular file:

#include <sys/types.h>
#include <sys/stat.h>
#include <unistd.h>

int is_regular_file(const char *path)
{
    struct stat path_stat;
    stat(path, &path_stat);
    return S_ISREG(path_stat.st_mode);
}

Note that there are other file types besides regular and directory, like devices, pipes, symbolic links, sockets, etc. You might want to take those into account.

Uncommenting extension=php_pgsql.dll in the php.ini configuration files does work but, you may have to also restart your XAMPP server to finally get it working. I had to do this.

Oracle has two different ways of making views updatable:-

1. The view is "key preserved" with respect to what you are trying to update. This means the primary key of the underlying table is in the view and the row appears only once in the view. This means Oracle can figure out exactly which underlying table row to update OR
2. You write an instead of trigger.

I would stay away from instead-of triggers and get your code to update the underlying tables directly rather than through the view.

Try

document.getElementsByTagName("Option").length=0

Or maybe look into the removeChild() function.

Or if you use jQuery framework.

$("DropList Option").each(function(){$(this).remove();});

Agree with previous answers.

A little correction: There's a better way to print the decimal digits from left to right, without allocating extra buffer. In addition you may want to display a zero characeter if the score is 0 (the loop suggested in the previous answers won't print anythng).

This demands an additional pass:

int div;
for (div = 1; div <= score; div *= 10)
    ;

do
{
    div /= 10;
    printf("%d\n", score / div);
    score %= div;
} while (score);

SlickGrid has this functionality, see the tree demo.

If you want to build your own, here is an example (jsFiddle demo): Build your table with a data-depth attribute to indicate the depth of the item in the tree (the levelX CSS classes are just for styling indentation): 

<table id="mytable">
    <tr data-depth="0" class="collapse level0">
        <td><span class="toggle collapse"></span>Item 1</td>
        <td>123</td>
    </tr>
    <tr data-depth="1" class="collapse level1">
        <td><span class="toggle"></span>Item 2</td>
        <td>123</td>
    </tr>
</table>

Then when a toggle link is clicked, use Javascript to hide all <tr> elements until a <tr> of equal or less depth is found (excluding those already collapsed):

$(function() {
    $('#mytable').on('click', '.toggle', function () {
        //Gets all <tr>'s  of greater depth below element in the table
        var findChildren = function (tr) {
            var depth = tr.data('depth');
            return tr.nextUntil($('tr').filter(function () {
                return $(this).data('depth') <= depth;
            }));
        };

        var el = $(this);
        var tr = el.closest('tr'); //Get <tr> parent of toggle button
        var children = findChildren(tr);

        //Remove already collapsed nodes from children so that we don't
        //make them visible. 
        //(Confused? Remove this code and close Item 2, close Item 1 
        //then open Item 1 again, then you will understand)
        var subnodes = children.filter('.expand');
        subnodes.each(function () {
            var subnode = $(this);
            var subnodeChildren = findChildren(subnode);
            children = children.not(subnodeChildren);
        });

        //Change icon and hide/show children
        if (tr.hasClass('collapse')) {
            tr.removeClass('collapse').addClass('expand');
            children.hide();
        } else {
            tr.removeClass('expand').addClass('collapse');
            children.show();
        }
        return children;
    });
});

I like to write a small plugin to make things cleaner:

$.fn.setClass = function(classes) {
    this.attr('class', classes);
    return this;
};

That way you can simply do

$('button').setClass('btn btn-primary');

PHP runs on the server and Javascript runs on the client, so you can't set a PHP variable to equal a Javascript variable without sending the value to the server. You can, however, set a Javascript variable to equal a PHP variable:

<script type="text/javascript">
  var foo = '<?php echo $foo ?>';
</script>

To send a Javascript value to PHP you'd need to use AJAX. With jQuery, it would look something like this (most basic example possible):

var variableToSend = 'foo';
$.post('file.php', {variable: variableToSend});

On your server, you would need to receive the variable sent in the post:

$variable = $_POST['variable'];

The best, non-VBA, way to do this is using the TEXT formula. It takes a string as an argument and converts it to a value.

For example, =TEXT ("0.4*A1",'##') will return the value of 0.4 * the value that's in cell A1 of that worksheet.

When using a negative step, notice that the answer is shifted to the right by 1.

i'll make an example, first decide what browser you want to emulate, in this case i chose Firefox 60.6.1esr (64-bit), and check what GET request it issues, this can be obtained with a simple netcat server (MacOS bundles netcat, most linux distributions bunles netcat, and Windows users can get netcat from.. Cygwin.org , among other places),

setting up the netcat server to listen on port 9999: nc -l 9999

now hitting http://127.0.0.1:9999 in firefox, i get:

$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate
Connection: keep-alive
Upgrade-Insecure-Requests: 1

now let us compare that with this simple script:

<?php
$ch=curl_init("http://127.0.0.1:9999");
curl_exec($ch);

i get:

$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
Accept: */*

there are several missing headers here, they can all be added with the CURLOPT_HTTPHEADER option of curl_setopt, but the User-Agent specifically should be set with CURLOPT_USERAGENT instead (it will be persistent across multiple calls to curl_exec() and if you use CURLOPT_FOLLOWLOCATION then it will persist across http redirections as well), and the Accept-Encoding header should be set with CURLOPT_ENCODING instead (if they're set with CURLOPT_ENCODING then curl will automatically decompress the response if the server choose to compress it, but if you set it via CURLOPT_HTTPHEADER then you must manually detect and decompress the content yourself, which is a pain in the ass and completely unnecessary, generally speaking) so adding those we get:

<?php
$ch=curl_init("http://127.0.0.1:9999");
curl_setopt_array($ch,array(
        CURLOPT_USERAGENT=>'Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0',
        CURLOPT_ENCODING=>'gzip, deflate',
        CURLOPT_HTTPHEADER=>array(
                'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
                'Accept-Language: en-US,en;q=0.5',
                'Connection: keep-alive',
                'Upgrade-Insecure-Requests: 1',
        ),
));
curl_exec($ch);

now running that code, our netcat server gets:

$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0
Accept-Encoding: gzip, deflate
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Connection: keep-alive
Upgrade-Insecure-Requests: 1

and voila! our php-emulated browser GET request should now be indistinguishable from the real firefox GET request :)

this next part is just nitpicking, but if you look very closely, you'll see that the headers are stacked in the wrong order, firefox put the Accept-Encoding header in line 6, and our emulated GET request puts it in line 3.. to fix this, we can manually put the Accept-Encoding header in the right line,

<?php
$ch=curl_init("http://127.0.0.1:9999");
curl_setopt_array($ch,array(
        CURLOPT_USERAGENT=>'Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0',
        CURLOPT_ENCODING=>'gzip, deflate',
        CURLOPT_HTTPHEADER=>array(
                'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
                'Accept-Language: en-US,en;q=0.5',
                'Accept-Encoding: gzip, deflate',
                'Connection: keep-alive',
                'Upgrade-Insecure-Requests: 1',
        ),
));
curl_exec($ch);

running that, our netcat server gets:

$ nc -l 9999
GET / HTTP/1.1
Host: 127.0.0.1:9999
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate
Connection: keep-alive
Upgrade-Insecure-Requests: 1

problem solved, now the headers is even in the correct order, and the request seems to be COMPLETELY INDISTINGUISHABLE from the real firefox request :) (i don't actually recommend this last step, it's a maintenance burden to keep CURLOPT_ENCODING in sync with the custom Accept-Encoding header, and i've never experienced a situation where the order of the headers are significant)

I just wrote a directive to handle this, so you can simply add the attribute bs-active-link to the parent <ul> element, and any time the route changed, it will find the matching link, and add the active class to the corresponding <li>.

You can see it in action here: http://jsfiddle.net/8mcedv3b/

Example HTML:

<ul class="nav navbar-nav" bs-active-link>
  <li><a href="/home">Home</a></li>
  <li><a href="/contact">Contact</a></li>
</ul>

Javascript:

angular.module('appName')
.directive('bsActiveLink', ['$location', function ($location) {
return {
    restrict: 'A', //use as attribute 
    replace: false,
    link: function (scope, elem) {
        //after the route has changed
        scope.$on("$routeChangeSuccess", function () {
            var hrefs = ['/#' + $location.path(),
                         '#' + $location.path(), //html5: false
                         $location.path()]; //html5: true
            angular.forEach(elem.find('a'), function (a) {
                a = angular.element(a);
                if (-1 !== hrefs.indexOf(a.attr('href'))) {
                    a.parent().addClass('active');
                } else {
                    a.parent().removeClass('active');   
                };
            });     
        });
    }
}
}]);

If all you want to do is store some static values in a lookup table, you can use an Object Literal (the same format used by JSON) to do it compactly:

var table = { one: [1,10,5], two: [2], three: [3, 30, 300] }

And then access them using JavaScript's associative array syntax:

alert(table['one']);    // Will alert with [1,10,5]
alert(table['one'][1]); // Will alert with 10

I think you are missing using System.Linq; from this system class.

and also add using System.Data.Entity; to the code

LinearLayout : A layout that organizes its children into a single horizontal or vertical row. It creates a scrollbar if the length of the window exceeds the length of the screen.It means you can align views one by one (vertically/ horizontally).

RelativeLayout : This enables you to specify the location of child objects relative to each other (child A to the left of child B) or to the parent (aligned to the top of the parent). It is based on relation of views from its parents and other views.

WebView : to load html, static or dynamic pages.

This blog post explains it perfectly: Ruby's Exception vs StandardError: What's the difference?

Why you shouldn't rescue Exception

The problem with rescuing Exception is that it actually rescues every exception that inherits from Exception. Which is....all of them!

That's a problem because there are some exceptions that are used internally by Ruby. They don't have anything to do with your app, and swallowing them will cause bad things to happen.

Here are a few of the big ones:

• SignalException::Interrupt - If you rescue this, you can't exit your app by hitting control-c.

• ScriptError::SyntaxError - Swallowing syntax errors means that things like puts("Forgot something) will fail silently.

• NoMemoryError - Wanna know what happens when your program keeps running after it uses up all the RAM? Me neither.

begin
  do_something()
rescue Exception => e
  # Don't do this. This will swallow every single exception. Nothing gets past it. 
end

I'm guessing that you don't really want to swallow any of these system-level exceptions. You only want to catch all of your application level errors. The exceptions caused YOUR code.

Luckily, there's an easy way to to this.

Rescue StandardError Instead

All of the exceptions that you should care about inherit from StandardError. These are our old friends:

NoMethodError - raised when you try to invoke a method that doesn't exist

TypeError - caused by things like 1 + ""

RuntimeError - who could forget good old RuntimeError?

To rescue errors like these, you'll want to rescue StandardError. You COULD do it by writing something like this:

begin
  do_something()
rescue StandardError => e
  # Only your app's exceptions are swallowed. Things like SyntaxErrror are left alone. 
end

But Ruby has made it much easier for use.

When you don't specify an exception class at all, ruby assumes you mean StandardError. So the code below is identical to the above code:

begin
  do_something()
rescue => e
  # This is the same as rescuing StandardError
end

This issue often happens when we try to merge another branch changes from a wrong directory.

Ex:

Branch2\Branch1_SubDir$ svn merge -rStart:End Branch1
         ^^^^^^^^^^^^
   Merging at wrong location

A conflict that gets thrown on its execution is :

Tree conflict on 'Branch1_SubDir'
   > local missing or deleted or moved away, incoming dir edit upon merge

And when you select q to quit resolution, you get status as:

 M      .
!     C Branch1_SubDir
      >   local missing or deleted or moved away, incoming dir edit upon merge
!     C Branch1_AnotherSubDir
      >   local missing or deleted or moved away, incoming dir edit upon merge

which clearly means that the merge contains changes related to Branch1_SubDir and Branch1_AnotherSubDir, and these folders couldn't be found inside Branch1_SubDir(obviously a directory can't be inside itself).

How to avoid this issue at first place:

Branch2$ svn merge -rStart:End Branch1
 ^^^^
Merging at root location

The simplest fix for this issue that worked for me :

svn revert -R .

Adding to Bartek Maciejiczek's answer, this is how it looks with Craco:

    const ModuleScopePlugin = require("react-dev-utils/ModuleScopePlugin");
    const path = require("path");

    module.exports = {
      webpack: {
        configure: webpackConfig => {
          webpackConfig.resolve.plugins.forEach(plugin => {
            if (plugin instanceof ModuleScopePlugin) {
              plugin.allowedFiles.add(path.resolve("./config.json"));
            }
          });
          return webpackConfig;
        }
      }
    };

    public static void setListViewHeightBasedOnChildren(ListView listView) {
    // ??ListView???Adapter
    ListAdapter listAdapter = listView.getAdapter();
    if (listAdapter == null) {
        return;
    }

    int totalHeight = 0;
    for (int i = 0, len = listAdapter.getCount(); i < len; i++) { // listAdapter.getCount()????????
        View listItem = listAdapter.getView(i, null, listView);
        listItem.measure(0, 0); // ????View ???
        totalHeight += listItem.getMeasuredHeight(); // ??????????
    }

    ViewGroup.LayoutParams params = listView.getLayoutParams();
    params.height = totalHeight
            + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
    // listView.getDividerHeight()?????????????
    // params.height??????ListView?????????
    listView.setLayoutParams(params);
}

you can use this code for listview in scrollview

var today = new Date(); 
    var dd = today.getDate(); 
    var mm = today.getMonth()+1;//January is 0! 
    var yyyy = today.getFullYear(); 
    var h = today.getHours();
       var m = today.getMinutes();
       var s = today.getSeconds();
    if(dd<10){dd='0'+dd} 
    if(mm<10){mm='0'+mm} 
    if(h<10){h='0'+h}
    if(m<10){m='0'+m} 
    if(s<10){s='0'+s}  
    onload = function(){ 
        $scope.currentTime=+dd+'/'+mm+'/'+yyyy+' '+h+':'+m+':'+s;
    }  

Sorry I am a beginner so my coding habit sucks!

public class TitleCase {

    String title(String sent)
    {   
        sent =sent.trim();
        sent = sent.toLowerCase();
        String[] str1=new String[sent.length()];
        for(int k=0;k<=str1.length-1;k++){
            str1[k]=sent.charAt(k)+"";
    }

        for(int i=0;i<=sent.length()-1;i++){
            if(i==0){
                String s= sent.charAt(i)+"";
                str1[i]=s.toUpperCase();
                }
            if(str1[i].equals(" ")){
                String s= sent.charAt(i+1)+"";
                str1[i+1]=s.toUpperCase();
                }

            System.out.print(str1[i]);
            }

        return "";
        }

    public static void main(String[] args) {
        TitleCase a = new TitleCase();
        System.out.println(a.title("   enter your Statement!"));
    }
}

For Windows Environments:

If you don't want to go to the command prompt (or work in an environment where command prompt is restricted), I think the following solution is better than inserting code into python that asks you to press any key - because if the program crashes before it reaches that point, the window closes and you lose the crash info. The solution I use is to create a bat file.

Use notepad to create a text file. In the file the contents will look something like:

my_python_program.py
pause

Then save the file as "my_python_program.bat"

When you run the bat file it will run the python program and pause at the end to allow you to read the output. Then if you press any key it will close the window.

This is an update to the code given by @HAdes to parameterize width, height, and ellipse size.

This implementation automatically calculates required angles, widths, and heights on the fly.

The user control is bound to itself (code-behind) which takes care of all calculations.

You can avoid the loop and cut etc by using:

awk -F ':' '{system("ping " $1);}' config.txt

However it would be better if you post a snippet of your config.txt

I found two links of performance compare among several ways of converting string to int.

parseInt(str,10)    
parseFloat(str)
str << 0
+str
str*1 
str-0
Number(str)

If you are using a zsh terminal you're able to use wildcard magic:

sed -i "" "s/search/high-replace/g" *.txt

If you are just running the server on your desktop, you can expose an endpoint to kill the server (read more at Shutdown The Simple Server):

from flask import request
def shutdown_server():
    func = request.environ.get('werkzeug.server.shutdown')
    if func is None:
        raise RuntimeError('Not running with the Werkzeug Server')
    func()
    
@app.route('/shutdown', methods=['GET'])
def shutdown():
    shutdown_server()
    return 'Server shutting down...'
    

Here is another approach that is more contained:

from multiprocessing import Process

server = Process(target=app.run)
server.start()
# ...
server.terminate()
server.join()

Let me know if this helps.

In the past months, I used a "preview" version of Android Studio. I tried to switch back to the "stable" releases for the software updates but it wasn't enough and I got this famous error you talk of.

Uninstalling my Android Studio 2.2.preview and installing latest stable Android Studio (2.1) fixed it for me :)

Something like this? Haven't tested it but should work fine.

function magic($obj, $var, $value = NULL)
{
    if($value == NULL)
    {
        return $obj->$var;
    }
    else
    {
        $obj->$var = $value;
    }
}

sudo apt-get install zlib1g:i386 fixed the Gradle issue on Android 2.1.1 on Xubuntu 16.04.

Adding to the mentions of jwplayer and possible TOS violations, I would like to to link to the following repository on github: YouTube Audio Player Generation Library, that allows to generate the following output:

Library has the support for the playlists and PHP autorendering given the video URL and the configuration options.

As simple as this !

var json_data = {"2013-01-21":1,"2013-01-22":7};
var result = [json_data];
console.log(result);

The input shape you have defined is the shape of a single sample. The model itself expects some array of samples as input (even if its an array of length 1).

Your output really should be 4-d, with the 1st dimension to enumerate the samples. i.e. for a single image you should return a shape of (1, 32, 32, 3).

You can find more information here under "Convolution2D"/"Input shape"

Edit: Based on Danny's comment below, if you want a batch size of 1, you can add the missing dimension using this:

image = np.expand_dims(image, axis=0)

If you are running in Android 29 then you have to use scoped storage or for now, you can bypass this issue by using:

android:requestLegacyExternalStorage="true"

in manifest in the application tag.

You can use the following code to both work with the command line and a web browser. Put this code above your PHP code. It creates a $_GET variable for each command line parameter.

In your code you only need to check for $_GET variables then, not worrying about if the script is called from the web browser or command line.

if(isset($argv))
    foreach ($argv as $arg) {
        $e=explode("=",$arg);
        if(count($e)==2)
            $_GET[$e[0]]=$e[1];
        else
            $_GET[$e[0]]=0;
    }

The response itself seems to have the size of the records. You can use that to check if records exist. Something like:

if($response->size > 0){
    $role_arr = getRole($response->records);
}

#include <string> would be the correct c++ include, also you need to specify the namespace with std::string or more generally with using namespace std;

According to MSDN

http://msdn.microsoft.com/ru-ru/library/system.data.sqlclient.sqlcommand.executenonquery(v=vs.110).aspx

result is the number of lines affected, and since your query is select no lines are affected (i.e. inserted, deleted or updated) anyhow.

If you want to return a single row of the query, use ExecuteScalar() instead of ExecuteNonQuery():

  int result = (int) (command.ExecuteScalar());

However, if you expect many rows to be returned, ExecuteReader() is the only option:

  using (SqlDataReader reader = command.ExecuteReader()) {
    while (reader.Read()) {
      int result = reader.GetInt32(0);

      ...
    }
  }

A simple Expect script:

File Remotelogin.exp

    #!/usr/bin/expect
    set user [lindex $argv 1]
    set ip [lindex $argv 0]
    set password [lindex $argv 2]
    spawn ssh $user@$ip
    expect "password"
    send "$password\r"
    interact

Example:

./Remotelogin.exp <ip> <user name> <password>

I also got this type error, problem is wrong usage of parameters to statement like, Let's say you have a query like this

SELECT * FROM EMPLOYE E WHERE E.ID = ?

and for the preparedStatement object (JDBC) if you set the parameters like

preparedStatement.setXXX(1,value);
preparedStatement.setXXX(2,value)

then it results in SQLException: Invalid column index

So, I removed that second parameter setting to prepared statement then problem solved

If you need to do something on the front end you can respond to the onsubmit event of your form. If you are just posting to admin/start you can access post variables in your view through the request object. request.POST which is a dictionary of post variables

Write to a file test.txt:

String filepath ="/mnt/sdcard/test.txt";
FileOutputStream fos = null;
try {
        fos = new FileOutputStream(filepath);
        byte[] buffer = "This will be writtent in test.txt".getBytes();
        fos.write(buffer, 0, buffer.length);
        fos.close();
    } catch (FileNotFoundException e) {
         e.printStackTrace();
    } catch (IOException e) {
         e.printStackTrace();
    }finally{
        if(fos != null)
            fos.close();
    }

Read from file test.txt:

String filepath ="/mnt/sdcard/test.txt";        
FileInputStream fis = null;
try {
       fis = new FileInputStream(filepath);
       int length = (int) new File(filepath).length();
       byte[] buffer = new byte[length];
       fis.read(buffer, 0, length);
       fis.close();
    } catch (FileNotFoundException e) {
         e.printStackTrace();
    } catch (IOException e) {
         e.printStackTrace();
    }finally{
        if(fis != null)
            fis.close();
   }

Note: don't forget to add these two permission in AndroidManifest.xml

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

zxing does not (only) provide a web API; really, that is Google providing the API, from source code that was later open-sourced in the project.

As Rob says here you can use the Java source code for the QR code encoder to create a raw barcode and then render it as a Bitmap.

I can offer an easier way still. You can call Barcode Scanner by Intent to encode a barcode. You need just a few lines of code, and two classes from the project, under android-integration. The main one is IntentIntegrator. Just call shareText().

This ought to work:

^\d+\s?(\([^\)]+\)\s?)?Z$

Haven't tested it though, but let me give you the breakdown, so if there are any bugs left they should be pretty straightforward to find:

First the beginning:

^ = beginning of string
\d+ = one or more decimal characters
\s? = one optional whitespace

Then this part:

(\([^\)]+\)\s?)?

Is actually:

(.............)?

Which makes the following contents optional, only if it exists fully

\([^\)]+\)\s?

\( = an opening bracket
[^\)]+ = a series of at least one character that is not a closing bracket
\) = followed by a closing bracket
\s? = followed by one optional whitespace

And the end is made up of

Z$

Where

Z = your constant string
$ = the end of the string

From GIT documentation: Git Docs

Below gives the full information. In short, simple will only push the current working branch and even then only if it also has the same name on the remote. This is a very good setting for beginners and will become the default in GIT 2.0

Whereas matching will push all branches locally that have the same name on the remote. (Without regard to your current working branch ). This means potentially many different branches will be pushed, including those that you might not even want to share.

In my personal usage, I generally use a different option: current which pushes the current working branch, (because I always branch for any changes). But for a beginner I'd suggest simple

push.default
Defines the action git push should take if no refspec is explicitly given. Different values are well-suited for specific workflows; for instance, in a purely central workflow (i.e. the fetch source is equal to the push destination), upstream is probably what you want. Possible values are:

nothing - do not push anything (error out) unless a refspec is explicitly given. This is primarily meant for people who want to avoid mistakes by always being explicit.

current - push the current branch to update a branch with the same name on the receiving end. Works in both central and non-central workflows.

upstream - push the current branch back to the branch whose changes are usually integrated into the current branch (which is called @{upstream}). This mode only makes sense if you are pushing to the same repository you would normally pull from (i.e. central workflow).

simple - in centralized workflow, work like upstream with an added safety to refuse to push if the upstream branch's name is different from the local one.

When pushing to a remote that is different from the remote you normally pull from, work as current. This is the safest option and is suited for beginners.

This mode will become the default in Git 2.0.

matching - push all branches having the same name on both ends. This makes the repository you are pushing to remember the set of branches that will be pushed out (e.g. if you always push maint and master there and no other branches, the repository you push to will have these two branches, and your local maint and master will be pushed there).

To use this mode effectively, you have to make sure all the branches you would push out are ready to be pushed out before running git push, as the whole point of this mode is to allow you to push all of the branches in one go. If you usually finish work on only one branch and push out the result, while other branches are unfinished, this mode is not for you. Also this mode is not suitable for pushing into a shared central repository, as other people may add new branches there, or update the tip of existing branches outside your control.

This is currently the default, but Git 2.0 will change the default to simple.

By XPath: inspect the element on target page, copy Xpath and use the below script:worked for me.

WebElement nameInputField = driver.findElement(By.xpath("html/body/div[6]/div[1]/div[3]/div/div/div[1]/div[3]/ul/li[4]/a"));
JavascriptExecutor executor = (JavascriptExecutor)driver;
executor.executeScript("arguments[0].click();", nameInputField);

I'd go for jpeg. Read this post regarding image size reduction and after deciding on the technique, use ImageMagick

Hope this helps

I added -adaptive-resize 60% to the suggested command, but with -quality 60%.

convert -strip -interlace Plane -gaussian-blur 0.05 -quality 60% -adaptive-resize 60% img_original.jpg img_resize.jpg

These were my results

• img_original.jpg = 13,913KB
• img_resized.jpg = 845KB

I'm not sure if that conversion destroys my image too much, but I honestly didn't think my conversion looked like crap. It was a wide angle panorama and I didn't care for meticulous obstruction.

<div class="row">
  <div class="col-xs-6 col-sm-4">Total cost</div>
  <div class="col-xs-6 col-sm-4"></div>
  <div class="clearfix visible-xs-block"></div>
  <div class="col-xs-6 col-sm-4">$42</div>
</div>

That should do the job just ok

Consider the figure enclosed in this other question. ebp-4 is your first local variable and, seen as a dword pointer, it is the address of a 32 bit integer that has to be cleared. Maybe your source starts with

Object x = null;

The len() function can be used with several different types in Python - both built-in types and library types. For example:

>>> len([1, 2, 3])
3

You can also achieve this through aggregate pipeline.

db.collection.aggregate([{$sort:{age:-1}}, {$limit:1}])

Use the modulus operator:

var fourPlaces = 0.5485M;
var twoPlaces = fourPlaces - (fourPlaces % 0.01M);

result: 0.54

Doing it this way has always worked for me, I hope this helps.

var ddl = $("#dropListBuilding");   
for (k = 0; k < buildings.length; k++)
   ddl.append("<option value='" + buildings[k]+ "'>" + buildings[k] + "</option>");

Sometimes it is necessary to load scripts in a specific order. For example jQuery must be loaded before jQuery UI. Most examples on this page load scripts in parallel (asynchronously) which means order of execution is not guaranteed. Without ordering, script y that depends on x could break if both are successfully loaded but in wrong order.

I propose a hybrid approach which allows sequential loading of dependent scripts + optional parallel loading + deferred objects:

/*_x000D_
 * loads scripts one-by-one using recursion_x000D_
 * returns jQuery.Deferred_x000D_
 */_x000D_
function loadScripts(scripts) {_x000D_

        }_x000D_
      });_x000D_
    } else {_x000D_

    }_x000D_

The scripts in both queues will download in parallel, however, the scripts in each queue will download in sequence, ensuring ordered execution. Waterfall chart:

Try this:

Get-WmiObject -Class "Win32_computersystem" | Format-List *
Get-WmiObject -Class "Win32_computersystem" | Format-List -Property *

For certain objects, PowerShell provides a set of formatting instructions that can affect either the table or list formats. These are usually meant to limit the display of reams of properties down to just the essential properties. However there are times when you really want to see everything. In those cases Format-List * will show all the properties. Note that in the case where you're trying to view a PowerShell error record, you need to use "Format-List * -Force" to truly see all the error information, for example,

$error[0] | Format-List * -force

Note that the wildcard can be used like a traditional wilcard this:

Get-WmiObject -Class "Win32_computersystem" | Format-List M*

Another way to do it:

<?php

$data = 'My data';

$menugen = function() use ($data) {

    echo "[".$data."]";
};

$menugen();

UPDATE 2020-01-13: requested by Peter Mortensen

As of PHP 5.3.0 we have anonymous functions support that can create closures. A closure can access the variable which is created outside of its scope.

In the example, the closure is able to access $data because it was declared in the use clause.

I found a little utility function a while back and I've been using it for resetting my form elements ever since (source: http://www.learningjquery.com/2007/08/clearing-form-data):

function clearForm(form) {
  // iterate over all of the inputs for the given form element
  $(':input', form).each(function() {
    var type = this.type;
    var tag = this.tagName.toLowerCase(); // normalize case
    // it's ok to reset the value attr of text inputs, 
    // password inputs, and textareas
    if (type == 'text' || type == 'password' || tag == 'textarea')
      this.value = "";
    // checkboxes and radios need to have their checked state cleared 
    // but should *not* have their 'value' changed
    else if (type == 'checkbox' || type == 'radio')
      this.checked = false;
    // select elements need to have their 'selectedIndex' property set to -1
    // (this works for both single and multiple select elements)
    else if (tag == 'select')
      this.selectedIndex = -1;
  });
};

... or as a jQuery plugin...

$.fn.clearForm = function() {
  return this.each(function() {
    var type = this.type, tag = this.tagName.toLowerCase();
    if (tag == 'form')
      return $(':input',this).clearForm();
    if (type == 'text' || type == 'password' || tag == 'textarea')
      this.value = '';
    else if (type == 'checkbox' || type == 'radio')
      this.checked = false;
    else if (tag == 'select')
      this.selectedIndex = -1;
  });
};

If there is not ISNULL() method, you can use this expression instead:

CASE WHEN fieldname IS NULL THEN 0 ELSE fieldname END

This works the same as ISNULL(fieldname, 0).

It might be easier to read when written out in longhand using the 'simple case' e.g.

CASE DeviceID 
   WHEN '7  ' THEN '01'
   WHEN '10 ' THEN '01'
   WHEN '62 ' THEN '01'
   WHEN '58 ' THEN '01'
   WHEN '60 ' THEN '01'
   WHEN '46 ' THEN '01'
   WHEN '48 ' THEN '01'
   WHEN '50 ' THEN '01'
   WHEN '137' THEN '01'
   WHEN '139' THEN '01'
   WHEN '142' THEN '01'
   WHEN '143' THEN '01'
   WHEN '164' THEN '01'
   WHEN '8  ' THEN '02'
   WHEN '9  ' THEN '02'
   WHEN '63 ' THEN '02'
   WHEN '59 ' THEN '02'
   WHEN '61 ' THEN '02'
   WHEN '47 ' THEN '02'
   WHEN '49 ' THEN '02'
   WHEN '51 ' THEN '02'
   WHEN '138' THEN '02'
   WHEN '140' THEN '02'
   WHEN '141' THEN '02'
   WHEN '144' THEN '02'
   WHEN '165' THEN '02'
   ELSE 'NA' 
END AS clocking

...which kind makes me thing that perhaps you could benefit from a lookup table to which you can JOIN to eliminate the CASE expression entirely.

You can enter -- INSERT (past) -- mode via:

• Keyboard combo: y p

or

• :set paste and entering insert mode (:set nopaste to disable)

once in -- INSERT (past) -- mode simply use your systems paste function (e.g. CtrlShiftv on Linux, Cmdv on Mac OS).

This strategy is very usefully when using vim over ssh.

a is an array local to the function.Once the function returns it does not exist anymore and hence you should not return the address of a local variable.
In other words the lifetime of a is within the scope({,}) of the function and if you return a pointer to it what you have is a pointer pointing to some memory which is not valid. Such variables are also called automatic variabels because their lifetime is automatically managed you do not need to manage it explicitly.

Since you need to extend the variable to persist beyond the scope of the function you You need to allocate a array on heap and return a pointer to it.

char *a = malloc(1000); 

This way the array a resides in memory untill you call a free() on the same address.
Do not forget to do so or you end up with a memory leak.

Fix: Unlock your device before running it.

Hi Guys: Think I may have a fix for this:

Sounds ridiculous but try unlocking your Virtual Device; i.e. use your mouse to swipe and open. Your app should then work!!

Try using this code for v3:

gMap = new google.maps.Map(document.getElementById('map')); 
gMap.setZoom(13);      // This will trigger a zoom_changed on the map
gMap.setCenter(new google.maps.LatLng(37.4419, -122.1419));
gMap.setMapTypeId(google.maps.MapTypeId.ROADMAP);

DateTime Picker can be used to pick both date and time that is why it is called 'Date and Time Picker'. You can set the "Format" property to "Custom" and set combination of different format specifiers to represent/pick date/time in different formats in the "Custom Format" property. However if you want to change Date, then the pop-up calendar can be used whereas in case of Time selection (in the same control you are bound to use up/down keys to change values.

For example a custom format " ddddd, MMMM dd, yyyy hh:mm:ss tt " will give you a result like this : "Thursday, August 20, 2009 02:55:23 PM".

You can play around with different combinations for format specifiers to suit your need e.g MMMM will give "August" whereas MM will give "Aug"

From Spring Boot 2, you will have to use

--spring.config.additional-location=production.properties

I have faced the same problem when I was working with an Ant script to build my application.

I use Eclipse for my application development, and I changed the compiler version in build properties of the project. But that didn't work for me. Then I found out that I can provide the compiler version in the Ant script.

I modified the Ant script at the section where it compile Java files.

<target name="build-java" depends="prepare-build">
    <echo message="Compiling java files"/>
    <javac ....
           target="1.5"...
    </javac>
</target>

This worked for me to resolve the unsupported major minor issue.

You can do this:

cat("File not supplied.\nUsage: ./program F=filename\n")

Notice that cat has a return value of NULL.

for XML line width, update preferences > XML > XML Files > Editor > Line width

JavaScript has associative arrays.

Here is a working snippet.

<script type="text/javascript">
  var myArray = [];
  myArray['thank'] = 'you';
  myArray['no'] = 'problem';
  console.log(myArray);
</script>

They are simply called objects.

You can use owin middleware to define cors policy in which you can define multiple cors origins

return new CorsOptions
        {
            PolicyProvider = new CorsPolicyProvider
            {
                PolicyResolver = context =>
                {
                    var policy = new CorsPolicy()
                    {
                        AllowAnyOrigin = false,
                        AllowAnyMethod = true,
                        AllowAnyHeader = true,
                        SupportsCredentials = true
                    };
                    policy.Origins.Add("http://foo.com");
                    policy.Origins.Add("http://bar.com");
                    return Task.FromResult(policy);
                }
            }
        };
