Passive event listeners are an emerging web standard, new feature shipped in Chrome 51 that provide a major potential boost to scroll performance. Chrome Release Notes.

It enables developers to opt-in to better scroll performance by eliminating the need for scrolling to block on touch and wheel event listeners.

Problem: All modern browsers have a threaded scrolling feature to permit scrolling to run smoothly even when expensive JavaScript is running, but this optimization is partially defeated by the need to wait for the results of any touchstart and touchmove handlers, which may prevent the scroll entirely by calling preventDefault() on the event.

Solution: {passive: true}

By marking a touch or wheel listener as passive, the developer is promising the handler won't call preventDefault to disable scrolling. This frees the browser up to respond to scrolling immediately without waiting for JavaScript, thus ensuring a reliably smooth scrolling experience for the user.

document.addEventListener("touchstart", function(e) {
    console.log(e.defaultPrevented);  // will be false
    e.preventDefault();   // does nothing since the listener is passive
    console.log(e.defaultPrevented);  // still false
}, Modernizr.passiveeventlisteners ? {passive: true} : false);

I had a semicolon at the end, and gave me this error.

Good article here https://github.com/vasanthk/react-bits/blob/master/patterns/27.passing-function-to-setState.md

// assuming this.state.count === 0
this.setState({count: this.state.count + 1});
this.setState({count: this.state.count + 1});
this.setState({count: this.state.count + 1});
// this.state.count === 1, not 3

Solution
this.setState((prevState, props) => ({
  count: prevState.count + props.increment
}));

or pass callback this.setState ({.....},callback)

I had named my file dockerfile instead of Dockerfile (capitalized), and once I changed that, it started processing my "Dockerfile".

I aso find this extremely confusing. as @EricMartinez points out Renderer2 listen() returns the function to remove the listener:

ƒ () { return element.removeEventListener(eventName, /** @type {?} */ (handler), false); }

If i´m adding a listener

this.listenToClick = this.renderer.listen('document', 'click', (evt) => {
    alert('Clicking the document');
})

I´d expect my function to execute what i intended, not the total opposite which is remove the listener.

// I´d expect an alert('Clicking the document'); 
this.listenToClick();
// what you actually get is removing the listener, so nothing...

In the given scenario, It´d actually make to more sense to name it like:

// Add listeners
let unlistenGlobal = this.renderer.listen('document', 'click', (evt) => {
    console.log('Clicking the document', evt);
})

let removeSimple = this.renderer.listen(this.myButton.nativeElement, 'click', (evt) => {
    console.log('Clicking the button', evt);
});

There must be a good reason for this but in my opinion it´s very misleading and not intuitive.

For those who mentioned Stringify() and toString() as solution, I will say that worked for me but we have to understand the problem and why did it occur. In my code it was simple issue. I had 2 buttons which call same function but one button was not passing the argument to that function properly.

A quicker way if you are using React 16.3 and above is by creating a ref in the constructor, then attaching it to the component you wish to use with as shown below.

...
constructor(props){
   ...
   //create a ref
   this.someRefName = React.createRef();

}

onScroll(){
let offsetTop = this.someRefName.current.offsetTop;

}

render(){
...
<Component ref={this.someRefName} />

}

1. To closed ideas,
2. To remove all folder and file C:/Users/UserName/.m2/org/*,
3. Open ideas and update Maven project,(right click on project -> maven->update maven project)
4. After that update the project.

I just came across this question in a search about destructors and I thought there was an unanswered part of your question in your comments, so I thought I would address that.

thank you guys. But what would be a good convention if ECMAScript doesn't have destructors? Should I create a method called destructor and call it manually when I'm done with the object? Any other idea?

If you want to tell your object that you are now done with it and it should specifically release any event listeners it has, then you can just create an ordinary method for doing that. You can call the method something like release() or deregister() or unhook() or anything of that ilk. The idea is that you're telling the object to disconnect itself from anything else it is hooked up to (deregister event listeners, clear external object references, etc...). You will have to call it manually at the appropriate time.

If, at the same time you also make sure there are no other references to that object, then your object will become eligible for garbage collection at that point.

ES6 does have weakMap and weakSet which are ways of keeping track of a set of objects that are still alive without affecting when they can be garbage collected, but it does not provide any sort of notification when they are garbage collected. They just disappear from the weakMap or weakSet at some point (when they are GCed).

FYI, the issue with this type of destructor you ask for (and probably why there isn't much of a call for it) is that because of garbage collection, an item is not eligible for garbage collection when it has an open event handler against a live object so even if there was such a destructor, it would never get called in your circumstance until you actually removed the event listeners. And, once you've removed the event listeners, there's no need for the destructor for this purpose.

I suppose there's a possible weakListener() that would not prevent garbage collection, but such a thing does not exist either.

FYI, here's another relevant question Why is the object destructor paradigm in garbage collected languages pervasively absent?. This discussion covers finalizer, destructor and disposer design patterns. I found it useful to see the distinction between the three.

Edit in 2020 - proposal for object finalizer

There is a Stage 3 EMCAScript proposal to add a user-defined finalizer function after an object is garbage collected.

A canonical example of something that would benefit from a feature like this is an object that contains a handle to an open file. If the object is garbage collected (because no other code still has a reference to it), then this finalizer scheme allows one to at least put a message to the console that an external resource has just been leaked and code elsewhere should be fixed to prevent this leak.

If you read the proposal thoroughly, you will see that it's nothing like a full-blown destructor in a language like C++. This finalizer is called after the object has already been destroyed and you have to predetermine what part of the instance data needs to be passed to the finalizer for it to do its work. Further, this feature is not meant to be relied upon for normal operation, but rather as a debugging aid and as a backstop against certain types of bugs. You can read the full explanation for these limitations in the proposal.

Thanks to David as his solution helped me come up with my solution for uploading multi-part files from my Heroku hosted site to S3 bucket. I did it using formidable to handle incoming form and fs to get the file content. Hopefully, it may help you.

api.service.ts

public upload(files): Observable<any> {  
    const formData: FormData = new FormData(); 
    files.forEach(file => {
      // create a new multipart-form for every file 
      formData.append('file', file, file.name);           
    });   
    return this.http.post(uploadUrl, formData).pipe(
      map(this.extractData),
      catchError(this.handleError)); 
  }
}

server.js

app.post('/api/upload', upload);
app.use('/api/upload', router);

upload.js

const IncomingForm = require('formidable').IncomingForm;
const fs = require('fs');
const AWS = require('aws-sdk');

module.exports = function upload(req, res) {
    var form = new IncomingForm();

    const bucket = new AWS.S3(
      {
        signatureVersion: 'v4',
        accessKeyId: process.env.AWS_ACCESS_KEY_ID,
        secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY,
        region: 'us-east-1'       
      }
    ); 

    form.on('file', (field, file) => {

        const fileContent = fs.readFileSync(file.path);

        const s3Params = {
            Bucket: process.env.AWS_S3_BUCKET,
            Key: 'folder/' + file.name,
            Expires: 60,             
            Body: fileContent,
            ACL: 'public-read'
        };

        bucket.upload(s3Params, function(err, data) {
            if (err) {
                throw err;
            }            
            console.log('File uploaded to: ' + data.Location);
            fs.unlink(file.path, function (err) {
              if (err) {
                  console.error(err);
              }
              console.log('Temp File Delete');
          });
        });
    });              

    // The second callback is called when the form is completely parsed. 
    // In this case, we want to send back a success status code.
    form.on('end', () => {        
      res.status(200).json('upload ok');
    });

    form.parse(req);
}

Event listeners

First off it's important to understand that there are two kinds of "event listeners":

1. Scope event listeners registered via $on:

   $scope.$on('anEvent', function (event, data) {
     ...
   });
   

2. Event handlers attached to elements via for example on or bind:

   element.on('click', function (event) {
     ...
   });
   

$scope.$destroy()

When $scope.$destroy() is executed it will remove all listeners registered via $on on that $scope.

It will not remove DOM elements or any attached event handlers of the second kind.

This means that calling $scope.$destroy() manually from example within a directive's link function will not remove a handler attached via for example element.on, nor the DOM element itself.

element.remove()

Note that remove is a jqLite method (or a jQuery method if jQuery is loaded before AngularjS) and is not available on a standard DOM Element Object.

When element.remove() is executed that element and all of its children will be removed from the DOM together will all event handlers attached via for example element.on.

It will not destroy the $scope associated with the element.

To make it more confusing there is also a jQuery event called $destroy. Sometimes when working with third-party jQuery libraries that remove elements, or if you remove them manually, you might need to perform clean up when that happens:

element.on('$destroy', function () {
  scope.$destroy();
});

What to do when a directive is "destroyed"

This depends on how the directive is "destroyed".

A normal case is that a directive is destroyed because ng-view changes the current view. When this happens the ng-view directive will destroy the associated $scope, sever all the references to its parent scope and call remove() on the element.

This means that if that view contains a directive with this in its link function when it's destroyed by ng-view:

scope.$on('anEvent', function () {
 ...
});

element.on('click', function () {
 ...
});

Both event listeners will be removed automatically.

However, it's important to note that the code inside these listeners can still cause memory leaks, for example if you have achieved the common JS memory leak pattern circular references.

Even in this normal case of a directive getting destroyed due to a view changing there are things you might need to manually clean up.

For example if you have registered a listener on $rootScope:

var unregisterFn = $rootScope.$on('anEvent', function () {});

scope.$on('$destroy', unregisterFn);

This is needed since $rootScope is never destroyed during the lifetime of the application.

The same goes if you are using another pub/sub implementation that doesn't automatically perform the necessary cleanup when the $scope is destroyed, or if your directive passes callbacks to services.

Another situation would be to cancel $interval/$timeout:

var promise = $interval(function () {}, 1000);

scope.$on('$destroy', function () {
  $interval.cancel(promise);
});

If your directive attaches event handlers to elements for example outside the current view, you need to manually clean those up as well:

var windowClick = function () {
   ...
};

angular.element(window).on('click', windowClick);

scope.$on('$destroy', function () {
  angular.element(window).off('click', windowClick);
});

These were some examples of what to do when directives are "destroyed" by Angular, for example by ng-view or ng-if.

If you have custom directives that manage the lifecycle of DOM elements etc. it will of course get more complex.

$scope.$emit: This method dispatches the event in the upwards direction (from child to parent)

$scope.$broadcast: Method dispatches the event in the downwards direction (from parent to child) to all the child controllers.

$scope.$on: Method registers to listen to some event. All the controllers which are listening to that event get notification of the broadcast or emit based on the where those fit in the child-parent hierarchy.

The $emit event can be cancelled by any one of the $scope who is listening to the event.

The $on provides the "stopPropagation" method. By calling this method the event can be stopped from propagating further.

Plunker :https://embed.plnkr.co/0Pdrrtj3GEnMp2UpILp4/

In case of sibling scopes (the scopes which are not in the direct parent-child hierarchy) then $emit and $broadcast will not communicate to the sibling scopes.

Look at the exception:

No qualifying bean of type [edu.java.spring.ws.dao.UserDao] found for dependency

This means that there's no bean available to fulfill that dependency. Yes, you have an implementation of the interface, but you haven't created a bean for that implementation. You have two options:

• Annotate UserDaoImpl with @Component or @Repository, and let the component scan do the work for you, exactly as you have done with UserService.
• Add the bean manually to your xml file, the same you have done with UserBoImpl.

Remember that if you create the bean explicitly you need to put the definition before the component scan. In this case the order is important.

You don't need to run any docker commands as sudo when you're using boot2docker as every command passed into the boot2docker VM runs as root by default.

You're seeing the error when you're running as sudo because sudo doesn't have the DOCKER_HOST env set, only your user does.

You can confirm this by doing a:

$ env

Then a

$ sudo env

And looking for DOCKER_HOST in each output.

As for having a docker file that runs your script, something like this might work for you:

Dockerfile

FROM busybox

# Copy your script into the docker image
ADD /path/to/your/script.sh /usr/local/bin/script.sh

# Run your script
CMD /usr/local/bin/script.sh

Then you can run:

docker build -t your-image-name:your-tag .

This will build your docker image, which you can see by doing a:

docker images

Then, to run your container, you can do a:

docker run your-image-name:your-tag

This run command will start a container from the image you created with your Dockerfile and your build command and then it will finish once your script.sh has finished executing.

Alexander Pavlov's answer gets the closest to what you want.

Due to the extensiveness of jQuery's abstraction and functionality, a lot of hoops have to be jumped in order to get to the meat of the event. I have set up this jsFiddle to demonstrate the work.

1. Setting up the Event Listener Breakpoint

You were close on this one.

1. Open the Chrome Dev Tools (F12), and go to the Sources tab.
2. Drill down to Mouse -> Click
   
   (click to zoom)

2. Click the button!

Chrome Dev Tools will pause script execution, and present you with this beautiful entanglement of minified code:

(click to zoom)

3. Find the glorious code!

Now, the trick here is to not get carried away pressing the key, and keep an eye out on the screen.

1. Press the F11 key (Step In) until desired source code appears
2. Source code finally reached
   • In the jsFiddle sample provided above, I had to press F11 108 times before reaching the desired event handler/function
   • Your mileage may vary, depending on the version of jQuery (or framework library) used to bind the events
   • With enough dedication and time, you can find any event handler/function

4. Explanation

I don't have the exact answer, or explanation as to why jQuery goes through the many layers of abstractions it does - all I can suggest is that it is because of the job it does to abstract away its usage from the browser executing the code.

Here is a jsFiddle with a debug version of jQuery (i.e., not minified). When you look at the code on the first (non-minified) breakpoint, you can see that the code is handling many things:

    // ...snip...

    if ( !(eventHandle = elemData.handle) ) {
        eventHandle = elemData.handle = function( e ) {
            // Discard the second event of a jQuery.event.trigger() and
            // when an event is called after a page has unloaded
            return typeof jQuery !== strundefined && jQuery.event.triggered !== e.type ?
                jQuery.event.dispatch.apply( elem, arguments ) : undefined;
        };
    }

    // ...snip...

The reason I think you missed it on your attempt when the "execution pauses and I jump line by line", is because you may have used the "Step Over" function, instead of Step In. Here is a StackOverflow answer explaining the differences.

Finally, the reason why your function is not directly bound to the click event handler is because jQuery returns a function that gets bound. jQuery's function in turn goes through some abstraction layers and checks, and somewhere in there, it executes your function.

It happen if there are two more ContextLoaderListener exist in your project.

For ex: in my case 2 ContextLoaderListener was exist using

1. java configuration
2. web.xml

So, remove any one ContextLoaderListener from your project and run your application.

HttpClientFactory

It's important to evaluate the different ways you can create an HttpClient, and part of that is understanding HttpClientFactory.

https://docs.microsoft.com/en-us/dotnet/architecture/microservices/implement-resilient-applications/use-httpclientfactory-to-implement-resilient-http-requests

This is not a direct answer I know - but you're better off starting here than ending up with new HttpClient(...) everywhere.

This Issue occurs if the application is unable to access the some_file_name.properties file.Make sure that the properties file is placed under resources folder in spring.

Trouble shooting Steps

1: Add the properties file under the resource folder.

2: If you don't have a resource folder. Create one by navigating new by Right click on the project new > Source Folder, name it as resource and place your properties file under it.

For annotation based Implementation

Add @PropertySource(ignoreResourceNotFound = true, value = "classpath:some_file_name.properties")//Add it before using the place holder

Example:

Assignment1Controller.Java

@PropertySource(ignoreResourceNotFound = true, value = "classpath:assignment1.properties")
@RestController  
public class Assignment1Controller {

//  @Autowired
//  Assignment1Services assignment1Services;
    @Value("${app.title}")
    private String appTitle;
     @RequestMapping(value = "/hello")  
        public String getValues() {

          return appTitle;

        }  

}

assignment1.properties

app.title=Learning Spring

I came across this issue twice once in upgrading to 3.2.18 from 3.2.1 and 4.3.5 from 3.2.8. In both cases, this error is because of different version of spring modules

I tried the binding according to the answer by @Szymon but It did not work for me. I tried basicHttpsBinding which is new in .net 4.5 and It solved the issue. Here is the complete configuration that works for me.

<system.serviceModel>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="false" />
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <serviceMetadata httpGetEnabled="false" httpsGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <bindings>
      <basicHttpsBinding>
        <binding name="basicHttpsBindingForYourService">
          <security mode="Transport">
            <transport clientCredentialType="None" proxyCredentialType="None"/>
          </security>
        </binding>
      </basicHttpsBinding>
    </bindings>
    <services>
      <service name="YourServiceName">
        <endpoint address="" binding="basicHttpsBinding" bindingName="basicHttpsBindingForYourService" contract="YourContract" />
      </service>
    </services>   
</system.serviceModel>

FYI: My application's target framework is 4.5.1. IIS web site that I created to deploy this wcf service only has https binding enabled.

If your only goal by removing the listeners is to stop them from running, you can add an event listener to the window capturing and canceling all events of the given type:

window.addEventListener(type, function (event) {
    event.stopPropagation();
}, true);

Passing in true for the third parameter causes the event to be captured on the way down. Stopping propagation means that the event never reaches the listeners that are listening for it.

Keep in mind though that this has very limited use as you can't add new listeners for the given type (they will all be blocked). There are ways to get around this somewhat, e.g., by firing a new kind of event that only your listeners would know to listen for. Here is how you can do that:

window.addEventListener('click', function (event) {
    // (note: not cross-browser)
    var event2 = new CustomEvent('click2', {detail: {original: event}});
    event.target.dispatchEvent(event2);
    event.stopPropagation();
}, true);

element.addEventListener('click2', function(event) {
    event = event.detail && event.detail.original ?
        event.detail.original :
        event;
    // ... do something with event ...
});

However, note that this may not work as well for fast events like mousemove, given that the re-dispatching of the event introduces a delay.

Better would be to just keep track of the listeners added in the first place, as outlined in Martin Wantke's answer, if you need to do this.

this happened to me too after adding the version tag, that was missing, to the maven-war-plugin (not sure what version was using by default, i changed to the latest, 2.6 in my case). I had to wipe .m2/repository to have the build succeed again.

I tried first to clean the maven-filtering folder (in the repo) but then instead of a MavenFilterException i was getting an ArchiverException. So i concluded the local repository was corrupted (for a version upgrade?) and i deleted everything.

That fixed it for me. Just clean your local repo.

export PYTHONPATH="/home/user/my_project":$PYTHONPATH

And don't forget to preserve previous content suffixing by :$PYTHONPATH (which is the value of the variable)

Execute the following command to check everything is configured correctly:

echo $PYTHONPATH

Never use .onclick(), or similar attributes from a userscript! (It's also poor practice in a regular web page).

The reason is that userscripts operate in a sandbox ("isolated world"), and onclick operates in the target-page scope and cannot see any functions your script creates.

Always use addEventListener()^Doc (or an equivalent library function, like jQuery .on()).

So instead of code like:

something.outerHTML += '<input onclick="resetEmotes()" id="btnsave" ...>'

You would use:

something.outerHTML += '<input id="btnsave" ...>'

document.getElementById ("btnsave").addEventListener ("click", resetEmotes, false);

For the loop, you can't pass data to an event listener like that See the doc. Plus every time you change innerHTML like that, you destroy the previous event listeners!

Without refactoring your code much, you can pass data with data attributes. So use code like this:

for (i = 0; i < EmoteURLLines.length; i++) {
    if (checkIMG (EmoteURLLines[i])) {
        localStorage.setItem ("nameEmotes", JSON.stringify (EmoteNameLines));
        localStorage.setItem ("urlEmotes", JSON.stringify (EmoteURLLines));
        localStorage.setItem ("usageEmotes", JSON.stringify (EmoteUsageLines));
        if (i == 0) {
            console.log (resetSlot ());
        }
        emoteTab[2].innerHTML  += '<span style="cursor:pointer;" id="' 
                                + EmoteNameLines[i] 
                                + '" data-usage="' + EmoteUsageLines[i] + '">'
                                + '<img src="' + EmoteURLLines[i] + '" /></span>'
                                ;
    } else {
        alert ("The maximum emote (" + EmoteNameLines[i] + ") size is (36x36)");
    }
}
//-- Only add events when innerHTML overwrites are done.
var targetSpans = emoteTab[2].querySelectorAll ("span[data-usage]");
for (var J in targetSpans) {
    targetSpans[J].addEventListener ("click", appendEmote, false);
}

Where appendEmote is like:

function appendEmote (zEvent) {
    //-- this and the parameter are special in event handlers.  see the linked doc.
    var emoteUsage  = this.getAttribute ("data-usage");
    shoutdata.value += emoteUsage;
}

WARNINGS:

• Your code reuses the same id for several elements. Don't do this, it's invalid. A given ID should occur only once per page.
• Every time you use .outerHTML or .innerHTML, you trash any event handlers on the affected nodes. If you use this method beware of that fact.

Reading your comments took me to a dirty fix. This is not a right way, I know, but can be a work around.

$(function() {
    $( "#inputFieldId" ).autocomplete({
        source: function( event, ui ) {
            alert("do your functions here");
            return false;
        }
    });
});

Deleting full .m2 local repository solved my problem, too.

If you don't know where it is, the locations are:

Unix/Mac OS X – ~/.m2/repository
Windows – C:\Documents and Settings\{your-username}\.m2\repository 
        ( %USERPROFILE%\.m2\repository too, as suggested by **MC Empero** )

You need upper case property names in your structs in order to be used by the json packages.

Upper case property names are exported properties. Lower case property names are not exported.

You also need to pass the your data object by reference (&data).

same thing as Nic007 said before.

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

From above only , just edited so it works right away

<script>
    var control = false;
    $(document).on('keyup keydown', function (e) {
        control = e.ctrlKey;
    });

    $(function () {
        $('#1x').on('click', function () {
            if (control) {
                // control-click
                alert("Control+Click");
            } else {
                // single-click
                alert("Single Click");
            }
        });
    }); 

</script>
<p id="1x">Click me</p>

You should always consider what the browser will see by the end. In this case, it will see this:

<img src='something' onmouseover='change(' ex1')' />

In other words, the "onmouseover" attribute is just change(, and there's another "attribute" called ex1')' with no value.

The truth is, HTML does not use \ for an escape character. But it does recognise " and ' as escaped quote and apostrophe, respectively.

Armed with this knowledge, use this:

document.getElementById("something").innerHTML = "<img src='something' onmouseover='change(&quot;ex1&quot;)' />";

... That being said, you could just use JavaScript quotes:

document.getElementById("something").innerHTML = "<img src='something' onmouseover='change(\"ex1\")' />";

Note, the localhost is a special string that FB allows here. If you didn't configure your debugging environment under localhost, you'll have to push it underneath that name as far as I can tell.

In my first answer the logic is shown for those who want to go with the logic only.

I think I was not able to make clear to @chalukya3545, that's why I am adding the whole code to let him know the exact flow of the code.

Add this permissions to your AndroidManifest.xml file:

 <uses-permission android:name="android.permission.BLUETOOTH" />  
 <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

The output for this code will look like this.

It is really simple.

googleMap.setInfoWindowAdapter(new InfoWindowAdapter() {

            // Use default InfoWindow frame
            @Override
            public View getInfoWindow(Marker marker) {              
                return null;
            }           

            // Defines the contents of the InfoWindow
            @Override
            public View getInfoContents(Marker marker) {

                // Getting view from the layout file info_window_layout
                View v = getLayoutInflater().inflate(R.layout.info_window_layout, null);

                // Getting reference to the TextView to set title
                TextView note = (TextView) v.findViewById(R.id.note);

                note.setText(marker.getTitle() );

                // Returning the view containing InfoWindow contents
                return v;

            }

        });

Just add above code in your class where you are using GoogleMap. R.layout.info_window_layout is our custom layout that is showing the view that will come in place of infowindow. I just added the textview here. You can add additonal view here to make it like the sample snap. My info_window_layout was

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

        <TextView 
        android:id="@+id/note"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

</LinearLayout>

I hope it will help. We can find a working example of custom infowindow at http://wptrafficanalyzer.in/blog/customizing-infowindow-contents-in-google-map-android-api-v2-using-infowindowadapter/#comment-39731

EDITED : This code is shows how we can add custom view on infoWindow. This code did not handle the clicks on Custom View items. So it is close to answer but not exactly the answer that's why It is not accepted as answer.

public class LoginTest extends BaseTest {
    @Test
    public void exampleTest( ){ 
        // Test
    }
}

Inherits from a base test class (this example is testng rather than jUnit, but the ActiveProfiles is the same):

@ContextConfiguration(locations = { "classpath:spring-test-config.xml" })
@ActiveProfiles(resolver = MyActiveProfileResolver.class)
public class BaseTest extends AbstractTestNGSpringContextTests { }

MyActiveProfileResolver can contain any logic required to determine which profile to use:

public class MyActiveProfileResolver implements ActiveProfilesResolver {
    @Override
    public String[] resolve(Class<?> aClass) {
        // This can contain any custom logic to determine which profiles to use
        return new String[] { "exampleProfile" };
    }
}

This sets the profile which is then used to resolve dependencies required by the test.

You can get with node.getScene, if you don't call from Platform.runLater, the result is a null value.

example null value:

node.getScene();

example no null value:

Platform.runLater(() -> {
    node.getScene().addEventFilter(KeyEvent.KEY_PRESSED, event -> {
               //your event
     });
});

Modern browsers

Plain JavaScript

If a DOM element which is removed is reference-free (no references pointing to it) then yes - the element itself is picked up by the garbage collector as well as any event handlers/listeners associated with it.

var a = document.createElement('div');
var b = document.createElement('p');
// Add event listeners to b etc...
a.appendChild(b);
a.removeChild(b);
b = null; 
// A reference to 'b' no longer exists 
// Therefore the element and any event listeners attached to it are removed.

However; if there are references that still point to said element, the element and its event listeners are retained in memory.

var a = document.createElement('div');
var b = document.createElement('p'); 
// Add event listeners to b etc...
a.appendChild(b);
a.removeChild(b); 
// A reference to 'b' still exists 
// Therefore the element and any associated event listeners are still retained.

jQuery

It would be fair to assume that the relevant methods in jQuery (such as remove()) would function in the exact same way (considering remove() was written using removeChild() for example).

However, this isn't true; the jQuery library actually has an internal method (which is undocumented and in theory could be changed at any time) called cleanData() (here is what this method looks like) which automatically cleans up all the data/events associated with an element upon removal from the DOM (be this via. remove(), empty(), html("") etc).

Older browsers

Older browsers - specifically older versions of IE - are known to have memory leak issues due to event listeners keeping hold of references to the elements they were attached to.

If you want a more in-depth explanation of the causes, patterns and solutions used to fix legacy IE version memory leaks, I fully recommend you read this MSDN article on Understanding and Solving Internet Explorer Leak Patterns.

A few more articles relevant to this:

• JScript memory leaks
• Memory leaks in IE8
• JavaScript Memory Leaks

Manually removing the listeners yourself would probably be a good habit to get into in this case (only if the memory is that vital to your application and you are actually targeting such browsers).

Using .on() you can define your function once, and it will execute for any dynamically added elements.

for example

$('#staticDiv').on('click', 'yourSelector', function() {
  //do something
});

It's unfortunately not so easy to do that. If you're trying to make some sort of text user interface, you may want to look into curses. If you want to display things like you normally would in a terminal, but want input like that, then you'll have to work with termios, which unfortunately appears to be poorly documented in Python. Neither of these options are that simple, though, unfortunately. Additionally, they do not work under Windows; if you need them to work under Windows, you'll have to use PDCurses as a replacement for curses or pywin32 rather than termios.

I was able to get this working decently. It prints out the hexadecimal representation of keys you type. As I said in the comments of your question, arrows are tricky; I think you'll agree.

#!/usr/bin/env python
import sys
import termios
import contextlib


@contextlib.contextmanager
def raw_mode(file):
    old_attrs = termios.tcgetattr(file.fileno())
    new_attrs = old_attrs[:]
    new_attrs[3] = new_attrs[3] & ~(termios.ECHO | termios.ICANON)
    try:
        termios.tcsetattr(file.fileno(), termios.TCSADRAIN, new_attrs)
        yield
    finally:
        termios.tcsetattr(file.fileno(), termios.TCSADRAIN, old_attrs)


def main():
    print 'exit with ^C or ^D'
    with raw_mode(sys.stdin):
        try:
            while True:
                ch = sys.stdin.read(1)
                if not ch or ch == chr(4):
                    break
                print '%02x' % ord(ch),
        except (KeyboardInterrupt, EOFError):
            pass


if __name__ == '__main__':
    main()

I know this is an old question, but I thought some might find this approach useful; it could be applied to any similarly repetitive code:

ES6

['click','ontouchstart'].forEach( evt => 
    element.addEventListener(evt, dosomething, false)
);

ES5

['click','ontouchstart'].forEach( function(evt) {
    element.addEventListener(evt, dosomething, false);
});

This way worked well for me, keeps code clean by keeping where you handle the message in its own inner class.

The handler you wish to use

Handler mIncomingHandler = new Handler(new IncomingHandlerCallback());

The inner class

class IncomingHandlerCallback implements Handler.Callback{

        @Override
        public boolean handleMessage(Message message) {

            // Handle message code

            return true;
        }
}

By reading your exception , It's sure that you forgot to autowire customerService

You should autowire your customerservice .

make following changes in your controller class

@Controller
public class CustomerController{

    @Autowired
    private Customerservice customerservice;
......other code......

}

Again your service implementation class

write

@Service
public class CustomerServiceImpl implements CustomerService {
    @Autowired
    private CustomerDAO customerDAO;
......other code......

.....add transactional methods
}

If you are using hibernate make necessary changes in your applicationcontext xml file(configuration of session factory is needed).

you should autowire sessionFactory set method in your DAO mplementation

note that i am using jdbc.properties file for jdbc url and driver specification

i encountered this error in quite a stupid way

@Autowired
// private Bean bean;

public void myMethod() {
  return;
}

what happened is that I commented a line for some reason and left the annotation which made spring think that the method needs to be autowired

The accepted answer provides the semantics on how to increase the limit, but as @voltrevo pointed out that warning is there for a reason and your code probably has a bug.

Consider the following buggy code:

//Assume Logger is a module that emits errors
var Logger = require('./Logger.js');

for (var i = 0; i < 11; i++) {
    //BUG: This will cause the warning
    //As the event listener is added in a loop
    Logger.on('error', function (err) {
        console.log('error writing log: ' + err)
    });

    Logger.writeLog('Hello');
}

Now observe the correct way of adding the listener:

//Good: event listener is not in a loop
Logger.on('error', function (err) {
    console.log('error writing log: ' + err)
});

for (var i = 0; i < 11; i++) {
    Logger.writeLog('Hello');
}

Search for similar issues in your code before changing the maxListeners (which is explained in other answers)

I think that the fastest way to do this is to just clone the node, which will remove all event listeners:

var old_element = document.getElementById("btn");
var new_element = old_element.cloneNode(true);
old_element.parentNode.replaceChild(new_element, old_element);

Just be careful, as this will also clear event listeners on all child elements of the node in question, so if you want to preserve that you'll have to resort to explicitly removing listeners one at a time.

I had a similar problem. The catalina.out logged this log Message

Apr 17, 2013 5:14:46 PM org.apache.catalina.core.StandardContext start SEVERE: Error listenerStart

Check the localhost.log in the tomcat log directory (in the same directory as catalina.out), to see the exception which caused this error.

I can't find a way to do this with code, but in stock Firefox 64, events are listed next to each HTML entity in the Developer Tools Inspector as noted on MDN's Examine Event Listeners page and as demonstrated in this image:

None of the solution helped me for my case.

I found the working solution though. I read that this happens when ADT plugin is not updated properly in Eclipse.

Solution
From Eclipse. . .
1. Go to Help Tap
2. Click Check for Updates

Update everything and whoa! No longer freezing at starting Eclipse!

Some compact syntax that achieves the desired result, POJS:

   "mousemove touchmove".split(" ").forEach(function(e){
      window.addEventListener(e,mouseMoveHandler,false);
    });

Note: Calling a lifecycle method from another one is not a good practice. In below example I tried to achieve that your onNewIntent will be always called irrespective of your Activity type.

OnNewIntent() always get called for singleTop/Task activities except for the first time when activity is created. At that time onCreate is called providing to solution for few queries asked on this thread.

You can invoke onNewIntent always by putting it into onCreate method like

@Override
public void onCreate(Bundle savedState){
    super.onCreate(savedState);
    onNewIntent(getIntent());
}

@Override
protected void onNewIntent(Intent intent) {
  super.onNewIntent(intent);
  //code
}

I strongly advice NOT to use the code:

process.setMaxListeners(0);

The warning is not there without reason. Most of the time, it is because there is an error hidden in your code. Removing the limit removes the warning, but not its cause, and prevents you from being warned of a source of resource leakage.

If you hit the limit for a legitimate reason, put a reasonable value in the function (the default is 10).

Also, to change the default, it is not necessary to mess with the EventEmitter prototype. you can set the value of defaultMaxListeners attribute like so:

require('events').EventEmitter.defaultMaxListeners = 15;

I had the same error by in SQL Server Management Studio.

I found that to look at the more specific error, look at the log file created by the SQL Server. When I opened the log file, I found this error

Could not connect because the maximum number of ’2' user connections has already been reached. The system administrator can use sp_configure to increase the maximum value. The connection has been closed

I spend quite some time figuring this out. Finally running the following code fixed my problem.

sp_configure 'show advanced options', 1;
go

reconfigure
go

sp_configure 'user connections', 0
go

reconfigure
go

Edit

To view logs search for "logs" on windows startup button, click "view events logs". From there go to Applications under "Windows Logs". You can also choose "System" logs to see system wise errors. You can use filter on current logs by clicking "Filter Current Logs" on right side and then select "Error checkbox".

Let's start by describing DOM elements' event handling.

DOM node event handling

First of all you wouldn't want to work with DOM node directly. Instead you probably would want to utilize Ext.Element interface. For the purpose of assigning event handlers, Element.addListener and Element.on (these are equivalent) were created. So, for example, if we have html:

<div id="test_node"></div>

and we want add click event handler.
Let's retrieve Element:

var el = Ext.get('test_node');

Now let's check docs for click event. It's handler may have three parameters:

click( Ext.EventObject e, HTMLElement t, Object eOpts )

Knowing all this stuff we can assign handler:

//       event name      event handler
el.on(    'click'        , function(e, t, eOpts){
  // handling event here
});

Widgets event handling

Widgets event handling is pretty much similar to DOM nodes event handling.

First of all, widgets event handling is realized by utilizing Ext.util.Observable mixin. In order to handle events properly your widget must containg Ext.util.Observable as a mixin. All built-in widgets (like Panel, Form, Tree, Grid, ...) has Ext.util.Observable as a mixin by default.

For widgets there are two ways of assigning handlers. The first one - is to use on method (or addListener). Let's for example create Button widget and assign click event to it. First of all you should check event's docs for handler's arguments:

click( Ext.button.Button this, Event e, Object eOpts )

Now let's use on:

var myButton = Ext.create('Ext.button.Button', {
  text: 'Test button'
});
myButton.on('click', function(btn, e, eOpts) {
  // event handling here
  console.log(btn, e, eOpts);
});

The second way is to use widget's listeners config:

var myButton = Ext.create('Ext.button.Button', {
  text: 'Test button',
  listeners : {
    click: function(btn, e, eOpts) {
      // event handling here
      console.log(btn, e, eOpts);
    }
  }
});

Notice that Button widget is a special kind of widgets. Click event can be assigned to this widget by using handler config:

var myButton = Ext.create('Ext.button.Button', {
  text: 'Test button',
  handler : function(btn, e, eOpts) {
    // event handling here
    console.log(btn, e, eOpts);
  }
});

Custom events firing

First of all you need to register an event using addEvents method:

myButton.addEvents('myspecialevent1', 'myspecialevent2', 'myspecialevent3', /* ... */);

Using the addEvents method is optional. As comments to this method say there is no need to use this method but it provides place for events documentation.

To fire your event use fireEvent method:

myButton.fireEvent('myspecialevent1', arg1, arg2, arg3, /* ... */);

arg1, arg2, arg3, /* ... */ will be passed into handler. Now we can handle your event:

myButton.on('myspecialevent1', function(arg1, arg2, arg3, /* ... */) {
  // event handling here
  console.log(arg1, arg2, arg3, /* ... */);
});

It's worth mentioning that the best place for inserting addEvents method call is widget's initComponent method when you are defining new widget:

Ext.define('MyCustomButton', {
  extend: 'Ext.button.Button',
  // ... other configs,
  initComponent: function(){
    this.addEvents('myspecialevent1', 'myspecialevent2', 'myspecialevent3', /* ... */);
    // ...
    this.callParent(arguments);
  }
});
var myButton = Ext.create('MyCustomButton', { /* configs */ });

Preventing event bubbling

To prevent bubbling you can return false or use Ext.EventObject.preventDefault(). In order to prevent browser's default action use Ext.EventObject.stopPropagation().

For example let's assign click event handler to our button. And if not left button was clicked prevent default browser action:

myButton.on('click', function(btn, e){
  if (e.button !== 0)
    e.preventDefault();
});

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.

If everything mentioned above does not work try the following. It worked for me.

Remove your project from the server > Restart server > Add your project to server > Restart server.

Detailed Instruction:

1. Right click on server > Add and Remove
2. Select your project > Remove > Finish
3. Restart your server
4. Right click on server > Add and Remove
5. Select your project > Add > Finish
6. Restart your server again.

Here is a modified form of the source based on my comment. Note that GUIs should be constructed & updated on the EDT, though I did not go that far.

make sure your properties file exist in classpath directory but not in sub folder of your classpath directory. if it is exist in sub folder then write as below classpath:subfolder/idm.properties

final ListView lv = (ListView) findViewById(R.id.ListView01);

lv.setOnItemClickListener(new OnItemClickListener() {
      public void onItemClick(AdapterView<?> myAdapter, View myView, int myItemInt, long mylng) {
        String selectedFromList =(String) (lv.getItemAtPosition(myItemInt));

      }                 
});

I hope this fixes your problem.

The following configuration taken from MSDN can be applied to enable tracing on your WCF service.

<configuration>
  <system.diagnostics>
    <sources>
      <source name="System.ServiceModel"
              switchValue="Information, ActivityTracing"
              propagateActivity="true" >
        <listeners>
             <add name="xml"/>
        </listeners>
      </source>
      <source name="System.ServiceModel.MessageLogging">
        <listeners>
            <add name="xml"/>
        </listeners>
      </source>
      <source name="myUserTraceSource"
              switchValue="Information, ActivityTracing">
        <listeners>
            <add name="xml"/>
        </listeners>
      </source>
    </sources>
    <sharedListeners>
        <add name="xml"
             type="System.Diagnostics.XmlWriterTraceListener"
             initializeData="Error.svclog" />
    </sharedListeners>
  </system.diagnostics>
</configuration>

To view the log file, you can use "C:\Program Files\Microsoft SDKs\Windows\v7.0A\bin\SvcTraceViewer.exe".

If "SvcTraceViewer.exe" is not on your system, you can download it from the "Microsoft Windows SDK for Windows 7 and .NET Framework 4" package here:

Windows SDK Download

You don't have to install the entire thing, just the ".NET Development / Tools" part.

When/if it bombs out during installation with a non-sensical error, Petopas' answer to Windows 7 SDK Installation Failure solved my issue.

You can create a PrintStream wrapping around your OutputStream and then just call it's print(String):

final OutputStream os = new FileOutputStream("/tmp/out");
final PrintStream printStream = new PrintStream(os);
printStream.print("String");
printStream.close();

Copy all order entries of home folder .iml file into your /src/main/main.iml file. This will solve the problem.

It is most likely that your configuration files are in src/main/resources, while they must be under src/test/resources to work properly under maven.

I'm replying this after two years 'cause I couldn't find this answer here and I think it is the right one.

in textView

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="New Text"
    android:onClick="onClick"
    android:clickable="true"

You must also implement View.OnClickListener and in On Click method can use intent

    Intent intent = new Intent(android.content.Intent.ACTION_VIEW);
           intent.setData(Uri.parse("https://youraddress.com"));    
            startActivity(intent);

I tested this solution works fine.

Updated approach - TextInputLayout:

Google has recently launched design support library and there is one component called TextInputLayout and it supports showing an error via setErrorEnabled(boolean) and setError(CharSequence).

How to use it?

Step 1: Wrap your EditText with TextInputLayout:

  <android.support.design.widget.TextInputLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/layoutUserName">

    <EditText
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:hint="hint"
      android:id="@+id/editText1" />

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

Step 2: Validate input

// validating input on a button click
public void btnValidateInputClick(View view) {

    final TextInputLayout layoutUserName = (TextInputLayout) findViewById(R.id.layoutUserName);
    String strUsername = layoutLastName.getEditText().getText().toString();

    if(!TextUtils.isEmpty(strLastName)) {
        Snackbar.make(view, strUsername, Snackbar.LENGTH_SHORT).show();
        layoutUserName.setErrorEnabled(false);
    } else {
        layoutUserName.setError("Input required");
        layoutUserName.setErrorEnabled(true);
    }
}

I have created an example over my Github repository, checkout the example if you wish to!

I encountered this error when the JDK that I compiled the app under was different from the tomcat JVM. I verified that the Tomcat manager was running jvm 1.6.0 but the app was compiled under java 1.7.0.

After upgrading Java and changing JAVA_HOME in our startup script (/etc/init.d/tomcat) the error went away.

You have an incompatibility between the version of ASM required by Hibernate (asm-1.5.3.jar) and the one required by Spring. But, actually, I wonder why you have asm-2.2.3.jar on your classpath (ASM is bundled in spring.jar and spring-core.jar to avoid such problems AFAIK). See HHH-2222.

Adding another answer to the bunch (no pun intended)...

You do need to call the doAnswer method if you can't\don't want to use spy's. However, you don't necessarily need to roll your own Answer. There are several default implementations. Notably, CallsRealMethods.

In practice, it looks something like this:

doAnswer(new CallsRealMethods()).when(mock)
        .voidMethod(any(SomeParamClass.class));

Or:

doAnswer(Answers.CALLS_REAL_METHODS.get()).when(mock)
        .voidMethod(any(SomeParamClass.class));

i dont know whether it is relevant to your issue, i got similar issue which i got solved by

1) In eclipse right click server and clean

if it still didnt work

2) export the project and delete the project create the project with same name and import the project and add the project to server and run.

As a lightweight alternative to GestureDetector you can use this class

public abstract class DoubleClickListener implements OnClickListener {

    private static final long DOUBLE_CLICK_TIME_DELTA = 300;//milliseconds

    long lastClickTime = 0;

    @Override
    public void onClick(View v) {
        long clickTime = System.currentTimeMillis();
        if (clickTime - lastClickTime < DOUBLE_CLICK_TIME_DELTA){
            onDoubleClick(v);
        } else {
            onSingleClick(v);
        }
        lastClickTime = clickTime;
    }

    public abstract void onSingleClick(View v);
    public abstract void onDoubleClick(View v);
}

Example:

    view.setOnClickListener(new DoubleClickListener() {

        @Override
        public void onSingleClick(View v) {

        }

        @Override
        public void onDoubleClick(View v) {

        }
    });

I found a better solution.

XML: (design.xml)

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent">
  <FrameLayout android:layout_width="90px" android:layout_height="90px">
    <RelativeLayout android:id="@+id/container" android:layout_width="fill_parent" android:layout_height="fill_parent">        
    </RelativeLayout>
</FrameLayout>
</FrameLayout>

Java Code:

public class Example extends Activity {
  private RelativeLayout container;
  private int currentX;
  private int currentY;

  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.design);

    container = (RelativeLayout)findViewById(R.id.container);

    int top = 0;
    int left = 0;

    ImageView image1 = ...
    RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
    layoutParams.setMargins(left, top, 0, 0);               
    container.addView(image1, layoutParams);

    ImageView image2 = ...
    left+= 100;
    RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
    layoutParams.setMargins(left, top, 0, 0);               
    container.addView(image2, layoutParams);

    ImageView image3 = ...
    left= 0;
    top+= 100;
    RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
    layoutParams.setMargins(left, top, 0, 0);               
    container.addView(image3, layoutParams);

    ImageView image4 = ...
    left+= 100;     
    RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
    layoutParams.setMargins(left, top, 0, 0);               
    container.addView(image4, layoutParams);
  }     

  @Override 
  public boolean onTouchEvent(MotionEvent event) {
    switch (event.getAction()) {
        case MotionEvent.ACTION_DOWN: {
            currentX = (int) event.getRawX();
            currentY = (int) event.getRawY();
            break;
        }

        case MotionEvent.ACTION_MOVE: {
            int x2 = (int) event.getRawX();
            int y2 = (int) event.getRawY();
            container.scrollBy(currentX - x2 , currentY - y2);
            currentX = x2;
            currentY = y2;
            break;
        }   
        case MotionEvent.ACTION_UP: {
            break;
        }
    }
      return true; 
  }
}

That's works!!!

If you want to load other layout or control, the structure is the same.

Surely it's a little extreme to say

...never use a for in loop to enumerate over an array. Never. Use good old for(var i = 0; i<arr.length; i++)

?

It is worth highlighting the section in the Douglas Crockford extract

...The second form should be used with objects...

If you require an associative array ( aka hashtable / dictionary ) where keys are named instead of numerically indexed, you will have to implement this as an object, e.g. var myAssocArray = {key1: "value1", key2: "value2"...};.

In this case myAssocArray.length will come up null (because this object doesn't have a 'length' property), and your i < myAssocArray.length won't get you very far. In addition to providing greater convenience, I would expect associative arrays to offer performance advantages in many situations, as the array keys can be useful properties (i.e. an array member's ID property or name), meaning you don't have to iterate through a lengthy array repeatedly evaluating if statements to find the array entry you're after.

Anyway, thanks also for the explanation of the JSLint error messages, I will use the 'isOwnProperty' check now when interating through my myriad associative arrays!

You could use a declarative module for lists of data such as query-js(*). In these situations I personally find a declarative approach less surprising

var funcs = Query.range(0,3).each(function(i){
     return  function() {
        console.log("My value: " + i);
    };
});

You could then use your second loop and get the expected result or you could do

funcs.iterate(function(f){ f(); });

(*) I'm the author of query-js and therefor biased towards using it, so don't take my words as a recommendation for said library only for the declarative approach :)

Using .insertAdjacentHTML() preserves event listeners, and is supported by all major browsers. It's a simple one-line replacement for .innerHTML.

var html_to_insert = "<p>New paragraph</p>";

// with .innerHTML, destroys event listeners
document.getElementById('mydiv').innerHTML += html_to_insert;

// with .insertAdjacentHTML, preserves event listeners
document.getElementById('mydiv').insertAdjacentHTML('beforeend', html_to_insert);

The 'beforeend' argument specifies where in the element to insert the HTML content. Options are 'beforebegin', 'afterbegin', 'beforeend', and 'afterend'. Their corresponding locations are:

<!-- beforebegin -->
<div id="mydiv">
  <!-- afterbegin -->
  <p>Existing content in #mydiv</p>
  <!-- beforeend -->
</div>
<!-- afterend -->

There are lots of great recommendations in the answers.

A general best practice is to consider who will be reading the log. In my case it will be an administrator at the client site. So I log messages that gives them something they can act on. For Example, "Unable to initialize application. This is usually caused by ......"

WebKit Inspector in Chrome or Safari browsers now does this. It will display the event listeners for a DOM element when you select it in the Elements pane.

Your best bet is to review the Java Swing tutorials, specifically the tutorial on Buttons.

The short code snippet is:

jBtnDrawCircle.addActionListener( /*class that implements ActionListener*/ );

WORKING SOLUTION

Let me add to this old post, a working solution I used to use that works in probably 80% or more of all browsers both new and old.

The solution is complex yet simple. The first step is to make use of CSS and guise the input file type with "under-elements" that show through as it has an opacity of 0. The next step is to use JavaScript to update its label as needed.

HTML _{The ID's are simply inserted if you wanted a quick way to access a specific element, the classes however, are a must as they relate to the CSS that sets this whole process up}

<div class="file-input wrapper">
    <input id="inpFile0" type="file" class="file-input control" />
    <div class="file-input content">
        <label id="inpFileOutput0" for="inpFileButton" class="file-input output">Click Here</label>
        <input id="inpFileButton0" type="button" class="file-input button" value="Select File" />
    </div>
</div>

CSS _{Keep in mind, coloring and font-styles and such are totally your preference, if you use this basic CSS, you can always use after-end mark up to style as you please, this is shown in the jsFiddle listed at the end.}

.file-test-area {
    border: 1px solid;
    margin: .5em;
    padding: 1em;
}
.file-input {
    cursor: pointer !important;
}
.file-input * {
    cursor: pointer !important;
    display: inline-block;
}
.file-input.wrapper {
    display: inline-block;
    font-size: 14px;
    height: auto;
    overflow: hidden;
    position: relative;
    width: auto;
}
.file-input.control {
    -moz-opacity:0 ;
    filter:alpha(opacity: 0);
    opacity: 0;

    height: 100%;
    position: absolute;
    text-align: right;
    width: 100%;
    z-index: 2;
}
.file-input.content {
    position: relative;
    top: 0px;
    left: 0px;
    z-index: 1;
}
.file-input.output {
    background-color: #FFC;
    font-size: .8em;
    padding: .2em .2em .2em .4em;
    text-align: center;
    width: 10em;
}
.file-input.button {
    border: none;
    font-weight: bold;
    margin-left: .25em;
    padding: 0 .25em;
}

JavaScript _{Pure and true, however, some OLDER (retired) browsers may still have trouble with it (like Netscrape 2!)}

var inp = document.getElementsByTagName('input');
for (var i=0;i<inp.length;i++) {
    if (inp[i].type != 'file') continue;
    inp[i].relatedElement = inp[i].parentNode.getElementsByTagName('label')[0];
    inp[i].onchange /*= inp[i].onmouseout*/ = function () {
        this.relatedElement.innerHTML = this.value;
    };
};

Working jsFiddle Example

DotNetCoders has a starter article on it: http://www.dotnetcoders.com/web/Articles/ShowArticle.aspx?article=50. They talk about how to set up the switches in the configuration file and how to write the code, but it is pretty old (2002).

There's another article on CodeProject: A Treatise on Using Debug and Trace classes, including Exception Handling, but it's the same age.

CodeGuru has another article on custom TraceListeners: Implementing a Custom TraceListener

int(limit) returns the value converted into an integer, and doesn't change it in place as you call the function (which is what you are expecting it to).

Do this instead:

limit = int(limit)

Or when definiting limit:

if 'limit' in user_data :
    limit = int(user_data['limit'])

I got this working on a join plus union.

(SELECT 
   table1.column1,
   table1.column2,
   foo1.column4
 FROM table1, table2, foo1, table5
 WHERE table5.somerecord = table1.column1
 ORDER BY table1.column1 ASC, table1.column2 DESC
)

UNION

(SELECT
    ... Another complex query as above
)

ORDER BY column1 DESC, column2 ASC

json_obj=json.dumps(a_dict, ensure_ascii=False)

Try -

   $(this).siblings(".bidbutton").addClass("disabled").attr("disabled", "");

After hours of struggling, I solved it by including the following within app/build.gradle:

android {
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

Here's an option if you have multiple records for each Customer and are looking for the latest balance for each (say they are dated records):

SELECT ID, BALANCE FROM (
    SELECT ROW_NUMBER() OVER (PARTITION BY ID ORDER BY DateModified DESC) as RowNum, ID, BALANCE
    FROM CUSTOMERS
) C
WHERE RowNum = 1

Another solution is:

protected void Application_Start()
{
    ...
    RequestValidator.Current = new MyRequestValidator();
}

public class MyRequestValidator: RequestValidator
{
    protected override bool IsValidRequestString(HttpContext context, string value, RequestValidationSource requestValidationSource, string collectionKey, out int validationFailureIndex)
    {
        bool result = base.IsValidRequestString(context, value, requestValidationSource, collectionKey, out validationFailureIndex);

        if (!result)
        {
            // Write your validation here
            if (requestValidationSource == RequestValidationSource.Form ||
                requestValidationSource == RequestValidationSource.QueryString)

                return true; // Suppress error message
        }
        return result;
    }
}

The 2018 ES6+ ANSWER IS:

    const arr = [1, 2, 3];

    arr.forEach((val, key, arr) => {
      if (Object.is(arr.length - 1, key)) {
        // execute last item logic
        console.log(`Last callback call at index ${key} with value ${val}` ); 
      }
    });

for(std::map<std::string, std::map<std::string, std::string> >::iterator outer_iter=map.begin(); outer_iter!=map.end(); ++outer_iter) {
    for(std::map<std::string, std::string>::iterator inner_iter=outer_iter->second.begin(); inner_iter!=outer_iter->second.end(); ++inner_iter) {
        std::cout << inner_iter->second << std::endl;
    }
}

or nicer in C++0x:

for(auto outer_iter=map.begin(); outer_iter!=map.end(); ++outer_iter) {
    for(auto inner_iter=outer_iter->second.begin(); inner_iter!=outer_iter->second.end(); ++inner_iter) {
        std::cout << inner_iter->second << std::endl;
    }
}

Here is another ES6 way of doing it with O(n) complexity

const result = Object.entries(
    ['pear', 'apple', 'orange', 'apple'].reduce((previous, current) => {
        if (previous[current] === undefined) previous[current] = 1;
        else previous[current]++;
        return previous;
    }, {})).reduce((previous, current) => (current[1] >= previous[1] ? current : previous))[0];
console.log("Max value : " + result);

Just utilize toString or toLocaleString I'd say. So:

var page_number:number = 3;
window.location.hash = page_number.toLocaleString();

These throw an error if page_number is null or undefined. If you don't want that you can choose the fix appropriate for your situation:

// Fix 1:
window.location.hash = (page_number || 1).toLocaleString();

// Fix 2a:
window.location.hash = !page_number ? "1" page_number.toLocaleString();

// Fix 2b (allows page_number to be zero):
window.location.hash = (page_number !== 0 && !page_number) ? "1" page_number.toLocaleString();

• There is no limit on objects per bucket.
• There is a limit of 100 buckets per account (you need to request amazon if you need more).
• There is no performance drop even if you store millions of objects in a single bucket.

From docs,

There is no limit to the number of objects that can be stored in a bucket and no difference in performance whether you use many buckets or just a few. You can store all of your objects in a single bucket, or you can organize them across several buckets.

When the normType is NORM_MINMAX, cv::normalize normalizes _src in such a way that the min value of dst is alpha and max value of dst is beta. cv::normalize does its magic using only scales and shifts (i.e. adding constants and multiplying by constants).

CV_8UC1 says how many channels dst has.

The documentation here is pretty clear: http://docs.opencv.org/modules/core/doc/operations_on_arrays.html#normalize

and your server should work fine.

I had the same issue. But in my case it was due to my branch's name. The branch's name automatically set in my GitHub repo as main instead of master.

git pull origin master (did not work).

I confirmed in GitHub if the name of the branch was actually master and found the the actual name was main. so the commands below worked for me. git pull origin main

simply add a border: 2px solid #e60000; to your 2nd div tag CSS.

Definitely it works

#Div2Id {
    border: 2px solid #e60000; --> color is your preference
}

npm install nodemon --save-dev

Next package.json on and

"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"start": "nodemon app.js"
}

Type on terminal (command prompt)

npm start

To get those that end with "jander"

$("[id$=jander]")

Actually, that does not delete the variable/property. All it will do is set its value to None, therefore the variable will still take up space in memory. If you want to completely wipe all existence of the variable from memory, you can just type:

If a hidden directory is not needed to be listed, I offer:

ls -l | grep "^d" | awk -F" " '{print $9}'

And if hidden directories are needed to be listed, use:

ls -Al | grep "^d" | awk -F" " '{print $9}'

Or

find -maxdepth 1 -type d | awk -F"./" '{print $2}'

Many of the previous answers used backtracking. This is the asymptotically optimal way O(n*n!) of generating permutations after initial sorting

I'm searched many answers that suggest me to type in cmd:

set path = "%path%;c:program files\java\jdk1.7.0\bin"

but this is WRONG!

the right solution is that you leave "set" and just type

path = %path%;c:program files\java\jdk1.7.0\bin

P/s: of course you have to replace "jdk1.7.0" folder by your current java version folder. This works well on win 7 32bit, but I think it also works on win 8 - try it!

Try

pip install pillow

If it doesn't work, try clearing the

Perhaps a nice idiom for declaring constants for a class in Swift is to just use a struct named MyClassConstants like the following.

struct MyClassConstants{
    static let testStr = "test"
    static let testStrLength = countElements(testStr)

    static let arrayOfTests: [String] = ["foo", "bar", testStr]
}

In this way your constants will be scoped within a declared construct instead of floating around globally.

Update

I've added a static array constant, in response to a comment asking about static array initialization. See Array Literals in "The Swift Programming Language".

Notice that both string literals and the string constant can be used to initialize the array. However, since the array type is known the integer constant testStrLength cannot be used in the array initializer.

Try mydatagrid.Items.Refresh()

chmod +x gradlew

Just run the above comment. that's all enjoy your coding...

I was trying to figure how to do this recently and while I like the most popular solution at the top, it simply would not work for me as I needed the names to be the alias's that I entered in the script so I used some batch files (with some help from a colleague) to accomplish custom table names.

The batch file that initiates the bcp has a line at the bottom of the script that executes another script that merges a template file with the header names and the file that was just exported with bcp using the code below. Hope this helps someone else that was in my situation.

echo Add headers from template file to exported sql files....
Echo School 0031
copy e:\genin\templates\TEMPLATE_Courses.csv + e:\genin\0031\courses0031.csv e:\genin\finished\courses0031.csv /b

Is this what you are trying?

Option Explicit

Public Sub SaveWorksheetsAsCsv()
    Dim WS As Worksheet
    Dim SaveToDirectory As String, newName As String

    SaveToDirectory = "H:\test\"

    For Each WS In ThisWorkbook.Worksheets
        newName = GetBookName(ThisWorkbook.Name) & "_" & WS.Name
        WS.Copy
        ActiveWorkbook.SaveAs SaveToDirectory & newName, xlCSV
        ActiveWorkbook.Close Savechanges:=False
    Next
End Sub

Function GetBookName(strwb As String) As String
    GetBookName = Left(strwb, (InStrRev(strwb, ".", -1, vbTextCompare) - 1))

If I understood your question, here is the solution :

    $.ajaxSetup({ cache: true});

and for specific calls

 $.ajax({
        url: ...,
        type: "GET",
        cache: false,           
        ...
    });

If you want opposite (cache for specific calls) you can set false at the beginning and true for specific calls.

You can use Apache Commons Configuration library. The best part of this is, it won't even mess up the properties file and keeps it intact (even comments).

Javadoc

PropertiesConfiguration conf = new PropertiesConfiguration("propFile.properties");
conf.setProperty("key", "value");
conf.save();    

If message.value[] is string:

if message.value[0] in ('/', '\'):
    do_stuff()

If it not str

You can set the placeholder text using an attributed string. Pass the color you want with the attributes:

var myTextField = UITextField(frame: CGRect(x: 0, y: 0, width: 200, height: 30))
myTextField.backgroundColor = .blue
myTextField.attributedPlaceholder = NSAttributedString(string: "placeholder text",
                             attributes: [NSForegroundColorAttributeName: UIColor.yellow])

For Swift 3+ use following:

myTextField.attributedPlaceholder = NSAttributedString(string: "placeholder text",
                             attributes: [NSAttributedStringKey.foregroundColor: UIColor.white])

For Swift 4.2 use following:

myTextField.attributedPlaceholder = NSAttributedString(string: "placeholder text",
                             attributes: [NSAttributedString.Key.foregroundColor: UIColor.white])

Add a new user environment variable (Windows 7):

1. Start Menu > Control Panel > System > Advanced System Settings (on the left) > Environment Variables


2. Add a new user variable (at the top) that points your home user directory:

   Variable name: ANDROID_SDK_HOME
   Variable value: a path to a directory of your choice

AVD Manager will use this directory to save its .android directory into it.

For those who may be interested, I blogged about my first foray into Android development...
Android "Hello World": a Tale of Woe

Alternatively, you can use the Rapid Environment Editor to set the environment variables.

Indeed, just as commented by Tim Williams, the way to make it work is pre-formatting as text. Thus, to do it all via VBA, just do that:

Cells(1, 1).NumberFormat = "@"
Cells(1, 1).Value = "1234,56"

I found a good tutorial on oreilly.com.

Example code:

<canvas id="canvas" width ='600px'></canvas><br />
Enter your Text here .The Text will get drawn on the canvas<br />
<input type="text" id="text" onKeydown="func();"></input><br />
</body><br />
<script>
function func(){
var e=document.getElementById("text"),t=document.getElementById("canvas"),n=t.getContext("2d");
n.fillStyle="#990000";n.font="30px futura";n.textBaseline="top";n.fillText(e.value,150,0);n.fillText("thank you, ",200,100);
n.fillText("Created by ashish",250,120)
}

Yes, this is a 'new style' object. It was a feature introduced in python2.2.

New style objects have a different object model to classic objects, and some things won't work properly with old style objects, for instance, super(), @property and descriptors. See this article for a good description of what a new style class is.

SO link for a description of the differences: What is the difference between old style and new style classes in Python?

editText.setFocusable(false);
editText.setClickable(false);

After looking at this and trying it out I found it actually didn't allow more than one instance of jquery to run at a time. After searching around I found that this did just the trick and was a whole lot less code.

    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript"></script>
    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js" type="text/javascript"></script>
    <script>var $j = jQuery.noConflict(true);</script>
    <script>
      $(document).ready(function(){
       console.log($().jquery); // This prints v1.4.2
       console.log($j().jquery); // This prints v1.9.1
      });
   </script>

So then adding the "j" after the "$" was all I needed to do.

$j(function () {
        $j('.button-pro').on('click', function () {
            var el = $('#cnt' + this.id.replace('btn', ''));
            $j('#contentnew > div').not(el).animate({
                height: "toggle",
                opacity: "toggle"
            }, 100).hide();
            el.toggle();
        });
    });

I will give you a simple solution for this one. In my case I don't have access to a server. In that case you can change the security policy in your Google Chrome browser to allow Access-Control-Allow-Origin. This is very simple:

1. Create a Chrome browser shortcut
2. Right click short cut icon -> Properties -> Shortcut -> Target

Simple paste in "C:\Program Files\Google\Chrome\Application\chrome.exe" --allow-file-access-from-files --disable-web-security.

The location may differ. Now open Chrome by clicking on that shortcut.

Hi for example if you have split and replace in String 07:05:45PM

var hour = time.replace("PM", "").split(":");

Result

[ '07', '05', '45' ]

It's like you are trying to access an object which is null. Consider below example:

TypeA objA;

At this time you have just declared this object but not initialized or instantiated. And whenever you try to access any property or method in it, it will throw NullPointerException which makes sense.

See this below example as well:

String a = null;
System.out.println(a.toString()); // NullPointerException will be thrown

You have to put a g at the end, it stands for "global":

echo dog dog dos | sed -r 's:dog:log:g'
                                     ^

Set up a trap (you can trap several signals with one handler):

signal (SIGQUIT, my_handler);
signal (SIGINT, my_handler);

Handle the signal however you want, but be aware of limitations and gotchas:

void my_handler (int sig)
{
  /* Your code here. */
}

Sometimes I also faced the problem of scrolling with Selenium. So I used javaScriptExecuter to achieve this.

For scrolling down:

WebDriver driver = new ChromeDriver();
JavascriptExecutor js = (JavascriptExecutor)driver;
js.executeScript("window.scrollBy(0, 250)", "");

Or, also

js.executeScript("scroll(0, 250);");

For scrolling up:

js.executeScript("window.scrollBy(0,-250)", "");

Or,

js.executeScript("scroll(0, -250);");

    public:
        MyTimer();
        QTimer *timer;

    public slots:
        void MyTimerSlot();
    };

    #endif // MYTIME

mytimer.cpp:

#include "mytimer.h"
#include <QDebug>

MyTimer::MyTimer()
{
    // create a timer
    timer = new QTimer(this);

    // setup signal and slot
    connect(timer, SIGNAL(timeout()),
          this, SLOT(MyTimerSlot()));

    // msec
    timer->start(1000);
}

void MyTimer::MyTimerSlot()
{
    qDebug() << "Timer...";
}

main.cpp:

#include <QCoreApplication>
#include "mytimer.h"

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    // Create MyTimer instance
    // QTimer object will be created in the MyTimer constructor
    MyTimer timer;

    return a.exec();
}

I know this is a very old question but it still doesn't have an accepted answer. I see that you want the following removed: html tags that are "empty" and white spaces based on an html string.

I have come up with a solution based on your comment for the output you are looking for:

Trimming using JavaScript<br /><br /><br /><br />all leading and trailing white spaces 

var str = "<p>&nbsp;&nbsp;</p><div>&nbsp;</div>Trimming using JavaScript<br /><br /><br /><br />all leading and trailing white spaces<p>&nbsp;&nbsp;</p><div>&nbsp;</div>";_x000D_
console.log(str.trim().replace(/&nbsp;/g, '').replace(/<[^\/>][^>]*><\/[^>]+>/g, ""));

.trim() removes leading and trailing whitespace

.replace(/ /g, '') removes  

.replace(/<[^\/>][^>]*><\/[^>]+>/g, "")); removes empty tags

Normally I would recommend floating but from your 3 requirements I would suggest this:

position: absolute;
right: 10px;
top: 5px;

Don't forget position: relative; on the parent div

why not just put the ng-controller one level higher,

<body ng-controller="ProjectController">
    <div ng-view><div>

And don't set controller in the route,

.when('/', { templateUrl: "abc.html" })

it works for me.

Here is a video on how to import.

Well, when writing it out to file, you do know what class T is, so you can store that in dump. Then, when reading it back in, you can dynamically call it using reflection.

public JSONObject dump() throws JSONException {
    JSONObject result = new JSONObject();
    JSONArray a = new JSONArray();
    for(T i : items){
        a.put(i.dump());
        // inside this i.dump(), store "class-name"
    }
    result.put("items", a);
    return result;
}

public void load(JSONObject obj) throws JSONException {
    JSONArray arrayItems = obj.getJSONArray("items");
    for (int i = 0; i < arrayItems.length(); i++) {
        JSONObject item = arrayItems.getJSONObject(i);
        String className = item.getString("class-name");
        try {
            Class<?> clazzy = Class.forName(className);
            T newItem = (T) clazzy.newInstance();
            newItem.load(obj);
            items.add(newItem);
        } catch (InstantiationException e) {
            // whatever
        } catch (IllegalAccessException e) {
            // whatever
        } catch (ClassNotFoundException e) {
            // whatever

Use pd.MultiIndex.from_product as an index in an otherwise empty dataframe, then reset its index, and you're done.

a = [1, 2, 3]
b = ["a", "b", "c"]

index = pd.MultiIndex.from_product([a, b], names = ["a", "b"])

pd.DataFrame(index = index).reset_index()

out:

   a  b
0  1  a
1  1  b
2  1  c
3  2  a
4  2  b
5  2  c
6  3  a
7  3  b
8  3  c

        };
    };
})(jQuery);

you only need call in this way:

    <script type="text/javascript">     
        $(document).ready(function () {
            $(".mybuttonselector").postconfirm({ locale: {
                        title: 'title',
                        text: 'message',
                        button: ['bt_0', 'bt_1'],
                        closeText: 'X'
                    }
                });
        });
    </script>

For multiple files; note the newer "multiple" attribute for input:

Form:

@using (Html.BeginForm("FileImport","Import",FormMethod.Post, new {enctype = "multipart/form-data"}))
{
    <label for="files">Filename:</label>
    <input type="file" name="files" multiple="true" id="files" />
    <input type="submit"  />
}

Controller:

[HttpPost]
public ActionResult FileImport(IEnumerable<HttpPostedFileBase> files)
{
    return View();
}

Why don't you use Array.filter?

var array = ['x','y','z'];
array.filter(function(item,index,array){return(item==YOURVAL)}).

Just copy that into your code, and here you go:

Array.prototype.inArray = function (searchedVal) {
return this.filter(function(item,index,array){return(item==searchedVal)}).length==true
}

This is the easiest way to do it: http://jsfiddle.net/thirtydot/jwJBd/

(or with table-layout: fixed for even width distribution: http://jsfiddle.net/thirtydot/jwJBd/59/)

This won't work in IE7.

#horizontal-style {
    display: table;
    width: 100%;
    /*table-layout: fixed;*/
}
#horizontal-style li {
    display: table-cell;
}
#horizontal-style a {
    display: block;
    border: 1px solid red;
    text-align: center;
    margin: 0 5px;
    background: #999;
}

You can use the standard JSON object, available in Javascript:

var a: any = {};
a.x = 10;
a.y='hello';
var jsonString = JSON.stringify(a);

I realize this is a very old thread, but it was very helpful when I had to put together some system documentation for several different servers that were hosting different versions of Sql Server. I ended up creating 4 stored procedures which I am posting here for the benefit of the community. We use Dynamics NAV so the two stored procedures with NAV in the name split the Nav company out of the table name. Enjoy...

1 of 4 - ListServerDatabases

Some browsers use their own way to read .css files. So the right way to beat this: If you type the command line directly in the .html source code, this beats the .css file, in that way, you told the browser directly what to do and the browser is at position not to read the commands from the .css file. Remember that the commands writen in the .html file is stronger than the command in the .css.

just an additional comment to the approved answer. You may get a crash when moving the cursor on edittext field due to parsing. I did a try catch statement, but implement your own code.

@Override public void onTextChanged(CharSequence s, int start, int before, int count) {
        if(!s.toString().equals(current)){
        amountEditText.removeTextChangedListener(this);

            String cleanString = s.toString().replaceAll("[$,.]", "");

            try{
                double parsed = Double.parseDouble(cleanString);
                String formatted = NumberFormat.getCurrencyInstance().format((parsed/100));
                current = formatted;
                amountEditText.setText(formatted);
                amountEditText.setSelection(formatted.length());
            } catch (Exception e) {

            }

            amountEditText.addTextChangedListener(this);
        }
    }

The equivalence would be

for i in (0...array.size)
end

or

(0...array.size).each do |i|
end

or

i = 0
while i < array.size do
   array[i]
   i = i + 1 # where you may freely set i to any value
end

I wanted to see how it works, I am creating the first extension, so I downloaded a simpler one.

Downloaded 'Typed URL History' sample from

this worked great, hope it helps

Somehow, where you are using Sentry, you're not using its Facade, but the class itself. When you call a class through a Facade you're not really using statics, it's just looks like you are.

Do you have this:

use Cartalyst\Sentry\Sentry; 

In your code?

Ok, but if this line is working for you:

$user = $this->sentry->register(array(     'username' => e($data['username']),     'email' => e($data['email']),      'password' => e($data['password'])     )); 

So you already have it instantiated and you can surely do:

$adminGroup = $this->sentry->findGroupById(5); 

This worked for me.

first of all, remove current remote :

git remote rm origin

second, add remote through HTTPS but git@xxx :

git remote add origin https://github.com/Sesamzaad/NET.git

then push has worked for me :

git push origin master

You need to remove the /var/lib/mysql folder. Also, purge when you remove the packages (I'm told this helps).

sudo apt-get remove --purge mysql-server mysql-client mysql-common

sudo rm -rf /var/lib/mysql

I was encountering similar issues. The second line got rid of my issues and allowed me to set up MySql from scratch. Hopefully it helps you too!

This working for me Try it

mongoexport --host cluster0-shard-dummy-link.mongodb.net:27017 --db yourdbname --forceTableScan   --collection users --type json --out /var/www/html/user.json --authenticationDatabase admin --ssl --username Yourusername --password Yourpassword

Above cmd return whole data of the users collection if you want filter field then add --fields=email,name

I think you can use REGEXP instead of LIKE

As the message says, you have a task which threw an unhandled exception.

Turn on Break on All Exceptions (Debug, Exceptions) and rerun the program.
This will show you the original exception when it was thrown in the first place.

(comment appended): In VS2015 (or above). Select Debug > Options > Debugging > General and unselect the "Enable Just My Code" option.

The SET command is TSQL specific - here's the PLSQL equivalent to what you posted:

v_date1 DATE := TO_DATE('03-AUG-2010', 'DD-MON-YYYY');

SELECT u.visualid
  FROM USAGE u 
 WHERE u.usetime > v_date1;

There's also no need for prefixing variables with "@"; I tend to prefix variables with "v_" to distinguish between variables & columns/etc.

See this thread about the Oracle equivalent of NOLOCK...

The error log is straightforward. As it suggested,You need to add 198.211.99.20 to your ALLOWED_HOSTS setting.

In your project settings.py file,set ALLOWED_HOSTS like this :

ALLOWED_HOSTS = ['198.211.99.20', 'localhost', '127.0.0.1']

For further reading read from here.

Your question contains the string literal "\b[A-Z]{2,}\b", but that \b will mean backspace, because there is no r-modifier.

Try: r"\b[A-Z]{2,}\b".

The problem is that since you are using ASP.NET controls with a runat attribute, the ID of the control is not actually "test1". It's "test1" with a long string attached to it.

I think you just need 'git show -c $ref'. Trying this on the git repository on a8e4a59 shows a combined diff (plus/minus chars in one of 2 columns). As the git-show manual mentions, it pretty much delegates to 'git diff-tree' so those options look useful.

You could try this below.

string url = "http://localhost:1302/TESTERS/Default6.aspx";

string fileName = System.IO.Path.GetFileName(url);

Hope this helps.

The problem is that $title is being referenced on line 5 before it's being assigned on line 58. Rearranging your code isn't easy, because the data is both retrieved and output at the same time. Just to test, how does something like this work?

Because you're only retrieving one row, you don't need to use a while loop, but I left it with hopes that it'll make it easier for you to relate to your current code. All I've done is removed the actual output from your data retrieval, and added variables for category and category name which are then referred to as usual later on. Also, I haven't tested this. :)

This easy query return a data type bit. You can use this thecnic for other data types:

select CAST(0 AS BIT) AS OK

A parameter is the variable which is part of the method’s signature (method declaration). An argument is an expression used when calling the method.

Consider the following code:

void Foo(int i, float f)
{
    // Do things
}

void Bar()
{
    int anInt = 1;
    Foo(anInt, 2.0);
}

Here i and f are the parameters, and anInt and 2.0 are the arguments.

Keytool comes with your Java library. So you have to execute the Keytool command from your /Library/Java/JavaVirtualMachines/jdk1.8.0_171.jdk/Contents/Home/jre/bin directory. Or you can add JAVA_HOME to your environmental variables (Windows) or ~/.bash_profile (Linux)

On a Linux Debian-based (so Ubuntu included) you have also to go to /etc/default/tomcat7, uncomment the #AUTHBIND=no line and set its value to 'yes', in order to let the server bind on a privileged port.

You may use line = line.rstrip('\n'). This will strip all newlines from the end of the string, not just one.

In your case, when you just select a single property, the easiest way is probably to bypass any formatting altogether:

get-qadgroupmember 'Domain Admins' | foreach { $_.Name }

This will get you a simple string[] without column headings or empty lines. The Format-* cmdlets are mainly for human consumption and thus their output is not designed to be easily machine-readable or -parseable.

For multiple properties I'd probably go with the -f format operator. Something along the lines of

alias | %{ "{0,-10}{1,-10}{2,-60}" -f $_.COmmandType,$_.Name,$_.Definition }

which isn't pretty but gives you easy and complete control over the output formatting. And no empty lines :-)

you can use this.

 DateTime dt0 = new DateTime(2009, 3, 10);
 DateTime dt1 = new DateTime(2009, 3, 26);

 for (; dt0.Date <= dt1.Date; dt0=dt0.AddDays(3))
 {
    //Console.WriteLine(dt0.Date.ToString("yyyy-MM-dd"));
    //take action
 }

This will give you the working directory of the current file.

File.dirname(__FILE__)

Example:

current_file: "/Users/nemrow/SITM/folder1/folder2/amazon.rb"

result: "/Users/nemrow/SITM/folder1/folder2"

Since pip v1.5, (released Jan 1 2014: CHANGELOG, PR) you may also specify a subdirectory of a git repo to contain your module. The syntax looks like this:

pip install -e git+https://git.repo/some_repo.git#egg=my_subdir_pkg&subdirectory=my_subdir_pkg # install a python package from a repo subdirectory

Note: As a pip module author, ideally you'd probably want to publish your module in it's own top-level repo if you can. Yet this feature is helpful for some pre-existing repos that contain python modules in subdirectories. You might be forced to install them this way if they are not published to pypi too.

The gap between the (bootstrap) input field and jquery-ui autocompleter seem to occur only in jQuery versions >= 3.2

When using jQuery version 3.1.1 it seem to not happen.

Possible reason is the notable update in v3.2.0 related to a bug fix on .width() and .height(). Check out the jQuery release notes for further details: v3.2.0 / v3.1.1

Bootstrap version 3.4.1 and jquery-ui version 1.12.0 used

This will work:

var cycles = cycleSource.AllCycles();

var settings = new JsonSerializerSettings
{
    ContractResolver = new CamelCasePropertyNamesContractResolver()
};

var vm = new JArray();

foreach (var cycle in cycles)
{
    var cycleJson = JObject.FromObject(cycle);
    // extend cycleJson ......
    vm.Add(cycleJson);
}

return vm;

Then after I tried to upload app via "Application Loader" and got success!

Yep. Had this same problem too. Here's the command I ran and it worked perfectly: convert transparent-img1.png transparent-img2.png transparent-img3.png -channel Alpha favicon.ico

Use stash; like this:

git add .
git reset Files/I/Want/To/Keep
git stash --keep-index
git commit -a -m "Done!"
git stash pop

If you accidentally commit a file, and want to rewrite your git history, use:

git reset HEAD~1 path/to/file
git commit -a -m "rollback"
git rebase -i HEAD~2

and squash to the two leading commits. You can write a helper script to do either of these if you have a known set of files you prefer not to automatically commit.

Just call mkdir C:\VTS no matter what. It will simply report that the subdirectory already exists.

Edit: As others have noted, this does set the %ERRORLEVEL% if the folder already exists. If your batch (or any processes calling it) doesn't care about the error level, this method works nicely. Since the question made no mention of avoiding the error level, this answer is perfectly valid. It fulfills the needs of creating the folder if it doesn't exist, and it doesn't overwrite the contents of an existing folder. Otherwise follow Martin Schapendonk's answer.

best and easiest way to do this

  public int getDays(String begin) throws ParseException {
     long MILLIS_PER_DAY = 24 * 60 * 60 * 1000;
     SimpleDateFormat dateFormat = new SimpleDateFormat("dd-MM-yyyy", Locale.ENGLISH);

    long begin = dateFormat.parse(begin).getTime();
    long end = new Date().getTime(); // 2nd date want to compare
    long diff = (end - begin) / (MILLIS_PER_DAY);
    return (int) diff;
}

Relation objects can be converted to arrays. This negates being able to use any ActiveRecord methods on them afterwards, but I didn't need to. I did this:

name_relation = first_name_relation + last_name_relation

Here is a good place to start. You can also try using this Office Open XML.

http://www.ecma-international.org/publications/standards/Ecma-376.htm

Kind of hacky, but the following should work :)

import os
filePath = "/foo/bar/baz.py"
serverPath = "/blah/boo/boom.py"
os.system("scp "+filePath+" [email protected]:"+serverPath)

To make this topic 'more complete'.

I required the column names and data types on a SELECT statement (not a table).

If you want to do this on a SELECT statement instead of an actual existing table, you can do the following:

DROP TABLE IF EXISTS abc;
CREATE TEMPORARY TABLE abc AS
-- your select statement here!
SELECT 
    *
FROM foo
-- end your select statement
;

select column_name, data_type 
from information_schema.columns 
where table_name = 'abc';
DROP IF EXISTS abc;

Short explanation, it makes a (temp) table of your select statement, which you can 'call' upon via the query provided by (among others) @a_horse_with_no_name and @selva.

Hope this helps.

In addition to several other points mentioned already:

Less surprise

that is, it is much easier to see what a piece of code will do do exactly . In C++ you need to approach guru level to be able to know exactly what code the compiler generates (try a combination of templates, multiple inheritance, auto generated constructors, virtual functions and mix in a bit of namespace magic and argument dependent lookup).

In many cases this magic is nice, but for example in real-time systems it can really screw up your day.

Check your line endings! If you see an error about the file not being found, followed by this "premature of end headers" error in your Apache log - it may be that you have Windows line endings in your script in instead of Unix style. I ran into that problem / solution.

Just in case somebody land here... since 8.1 you can simply use:

SELECT user_id 
FROM user_logs 
WHERE login_date BETWEEN SYMMETRIC '2014-02-01' AND '2014-02-28'

From the docs:

BETWEEN SYMMETRIC is the same as BETWEEN except there is no requirement that the argument to the left of AND be less than or equal to the argument on the right. If it is not, those two arguments are automatically swapped, so that a nonempty range is always implied.

An additional note. If you check uncompressed javascript file, you will find the condition:

if(window.Tether === undefined) {
     throw new Error('Bootstrap tooltips require Tether (http://github.hubspot.com/tether)')
}

So the error message contains the required information.

You can download the archive from that link.

Uncompressed version:

https://rawgit.com/HubSpot/tether/master/src/js/tether.js https://rawgit.com/HubSpot/tether/master/dist/css/tether.css

Note that it is now possible to use some of C++11 std::thread in the win32 threading mode. These header-only adapters worked out of the box for me: https://github.com/meganz/mingw-std-threads

From the revision history it looks like there is some recent attempt to make this a part of the mingw64 runtime.

That would be:

b.rstrip('\n')

If you want to strip space from each and every line, you might consider instead:

a.read().splitlines()

This will give you a list of lines, without the line end characters.

There isn't any need to use echo, sir. Just use the tag <plaintext>:

<plaintext>
    <div>
        <h3><a href="#">First</a></h3>
        <div>Lorem ipsum dolor sit amet.</div>
    </div>

In case you want to train CNN's with the theano backend like the Keras mnist_cnn.py example:

You better use theano bleeding edge version. Otherwise there may occur assertion errors.

• Run Theano bleeding edge
  pip install --upgrade --no-deps git+git://github.com/Theano/Theano.git
• Run Keras (like 1.0.8 works fine)
  pip install git+git://github.com/fchollet/keras.git

Here is the code..,how to position the jQuery UI dialog to center......

var $about = $("#about");

   $("#about_button").click(function() {
      $about.dialog({
         modal: true,
         title: "About the calendar",
         width: 600,         
         close: function() {
            $about.dialog("destroy");
            $about.hide();
         },
         buttons: {
            close : function() {
               $about.dialog("close");
            }
         }
      }).show();

      $about.dialog("option", "position", 'center');

   });

//get dimensions 
var height = $(window).height();
var width = $(window).width();

//refresh on resize
$(window).resize(function() {
  location.reload(true)
});

not sure if you wanted to tinker with the dimensions of elements or actually refresh the page. so here a bunch of different things pick what you want. you can even put the height and width in the resize event if you really wanted.

I had the same issue with the Android 10 emulator and I was able to solve the problem by following the steps below:

1. Go to Settings ? Network & internet ? Advanced ? Private DNS
2. Select Private DNS provider hostname
3. Enter: dns.google
4. Click Save

With this setup, you URL should work as expected.

If you are getting your gems from a public GitHub repository, you can use the shorthand

gem 'nokogiri', github: 'tenderlove/nokogiri'

Just try this first. It is my personal experience.

I had the same problem. What i had done is just permanently disable the antivirus (Mine was Avast Security 2015). Just after disabling the antivirus , thing gone well. the gradle finished successfully. From now within seconds the gradle is finishing ( Only taking 5-10 secs).

you can add infinite borders using box-shadow using css3 suppose you want to apply multiple borders on one div then code is like:

div {
    border-radius: 4px;
    /* #1 */
    border: 5px solid hsl(0, 0%, 40%);
    
    /* #2 */
    padding: 5px;
    background: hsl(0, 0%, 20%);
    
    /* #3 */
    outline: 5px solid hsl(0, 0%, 60%);
    
    /* #4 AND INFINITY!!! (CSS3 only) */
    box-shadow:
        0 0 0 10px red,
        0 0 0 15px orange,
        0 0 0 20px yellow,
        0 0 0 25px green,
        0 0 0 30px blue;
}

According to Yashu's instructions, I wrote the following function (it's PL/SQL code, but it should be easily adaptable to any other language).

FUNCTION field(str IN VARCHAR2) RETURN VARCHAR2 IS
    C_NEWLINE CONSTANT CHAR(1) := '
'; -- newline is intentional

    v_aux VARCHAR2(32000);
    v_has_double_quotes BOOLEAN;
    v_has_comma BOOLEAN;
    v_has_newline BOOLEAN;
BEGIN
    v_has_double_quotes := instr(str, '"') > 0;
    v_has_comma := instr(str,',') > 0;
    v_has_newline := instr(str, C_NEWLINE) > 0;

    IF v_has_double_quotes OR v_has_comma OR v_has_newline THEN
        IF v_has_double_quotes THEN
            v_aux := replace(str,'"','""');
        ELSE
            v_aux := str;
        END IF;
        return '"'||v_aux||'"';
    ELSE
        return str;
    END IF;
END;

You don't.

If you want to extend Person with Student, just do:

public class Student extends Person
{
}

And make sure, when you compile both classes, one can find the other one.

What IDE are you using?

According to cppreference, nullptr is a keyword that:

denotes the pointer literal. It is a prvalue of type std::nullptr_t. There exist implicit conversions from nullptr to null pointer value of any pointer type and any pointer to member type. Similar conversions exist for any null pointer constant, which includes values of type std::nullptr_t as well as the macro NULL.

So nullptr is a value of a distinct type std::nullptr_t, not int. It implicitly converts to the null pointer value of any pointer type. This magic happens under the hood for you and you don't have to worry about its implementation. NULL, however, is a macro and it is an implementation-defined null pointer constant. It's often defined like this:

#define NULL 0

i.e. an integer.

This is a subtle but important difference, which can avoid ambiguity.

For example:

int i = NULL;     //OK
int i = nullptr;  //error
int* p = NULL;    //OK
int* p = nullptr; //OK

and when you have two function overloads like this:

void func(int x);   //1)
void func(int* x);  //2)

func(NULL) calls 1) because NULL is an integer. func(nullptr) calls 2) because nullptr converts implicitly to a pointer of type int*.

Also if you see a statement like this:

auto result = findRecord( /* arguments */ );

if (result == nullptr)
{
 ...
}

and you can't easily find out what findRecord returns, you can be sure that result must be a pointer type; nullptr makes this more readable.

In a deduced context, things work a little differently. If you have a template function like this:

template<typename T>
void func(T *ptr)
{
    ...
}

and you try to call it with nullptr:

func(nullptr);

you will get a compiler error because nullptr is of type nullptr_t. You would have to either explicitly cast nullptr to a specific pointer type or provide an overload/specialization for func with nullptr_t.

• avoid ambiguity between function overloads
• enables you to do template specialization
• more secure, intuitive and expressive code, e.g. if (ptr == nullptr) instead of if (ptr == 0)

You can use a session variable to store the latest Sort Expression and when you sort the grid next time compare the sort expression of the grid with the Session variable which stores last sort expression. If the columns are equal then check the direction of the previous sort and sort in the opposite direction.

Example:

DataTable sourceTable = GridAttendence.DataSource as DataTable;
DataView view = new DataView(sourceTable);
string[] sortData = ViewState["sortExpression"].ToString().Trim().Split(' ');
if (e.SortExpression == sortData[0])
{
    if (sortData[1] == "ASC")
    {
        view.Sort = e.SortExpression + " " + "DESC";
        this.ViewState["sortExpression"] = e.SortExpression + " " + "DESC";
    }
    else
    {
        view.Sort = e.SortExpression + " " + "ASC";
        this.ViewState["sortExpression"] = e.SortExpression + " " + "ASC";
    }
}
else
{
    view.Sort = e.SortExpression + " " + "ASC";
    this.ViewState["sortExpression"] = e.SortExpression + " " + "ASC";
}

A) The main GUI thread will run endlessly on the call to Application.Run, so your while loop will never be reached

B) You would never want to have an endless loop like that (the while(true) loop) - it would simply freeze the thread. Not really sure what you're trying to achieve there.

I would create and show the "main" (initial) form in the Main method (as Visual Studio does for you by default). Then in your button handler, create the other form and show it as well as hiding the main form (not closing it). Then, ensure that the main form is shown again when that form is closed via an event. Example:

public partial class Form1 : Form
{
  public Form1()
  {
    InitializeComponent();
  }    

  private void button1_Click(object sender, EventArgs e)
  {      
    Form2 otherForm = new Form2();
    otherForm.FormClosed += new FormClosedEventHandler(otherForm_FormClosed);
    this.Hide();
    otherForm.Show();      
  }

  void otherForm_FormClosed(object sender, FormClosedEventArgs e)
  {
    this.Show();      
  }
}

I was pretty sure that you need to specify the NOLOCK for each JOIN in the query. But my experience was limited to SQL Server 2005.

When I looked up MSDN just to confirm, I couldn't find anything definite. The below statements do seem to make me think, that for 2008, your two statements above are equivalent though for 2005 it is not the case:

[SQL Server 2008 R2]

All lock hints are propagated to all the tables and views that are accessed by the query plan, including tables and views referenced in a view. Also, SQL Server performs the corresponding lock consistency checks.

[SQL Server 2005]

In SQL Server 2005, all lock hints are propagated to all the tables and views that are referenced in a view. Also, SQL Server performs the corresponding lock consistency checks.

Additionally, point to note - and this applies to both 2005 and 2008:

The table hints are ignored if the table is not accessed by the query plan. This may be caused by the optimizer choosing not to access the table at all, or because an indexed view is accessed instead. In the latter case, accessing an indexed view can be prevented by using the OPTION (EXPAND VIEWS) query hint.

Using JavaScript native Date functions you can get hours, minutes and seconds as you want. If you wish to format date and time in particular way you may want to implement a method extending JavaScript Date prototype.

Here is one already implemented: https://github.com/jacwright/date.format

e.g.

 ColorTranslator.ToHtml(Color.FromArgb(Color.Tomato.ToArgb()))

This can avoid the KnownColor trick.

You missed the closing tag for the input fields, and you can choose any one of the events, ex: onload, onclick etc.

(a) Onload event:

<script type="text/javascript">
$(document).ready(function(){
     $('#frm1').submit();
});
</script>

(b) Onclick Event:

<form name="frm1" id="frm1" action="../somePage" method="post">
    Please Waite... 
    <input type="hidden" name="uname" id="uname" value=<?php echo $uname;?> />
    <input type="hidden" name="price" id="price" value=<?php echo $price;?> />
    <input type="text" name="submit" id="submit" value="submit">
</form>
<script type="text/javascript">
$('#submit').click(function(){
     $('#frm1').submit();
});
</script>

There is another way of using Uri and we can achieve the same goal

http://api.example.org/data/2.5/forecast/daily?q=94043&mode=json&units=metric&cnt=7

To build the Uri you can use this:

final String FORECAST_BASE_URL = 
    "http://api.example.org/data/2.5/forecast/daily?";
final String QUERY_PARAM = "q";
final String FORMAT_PARAM = "mode";
final String UNITS_PARAM = "units";
final String DAYS_PARAM = "cnt";

You can declare all this the above way or even inside the Uri.parse() and appendQueryParameter()

Uri builtUri = Uri.parse(FORECAST_BASE_URL)
    .buildUpon()
    .appendQueryParameter(QUERY_PARAM, params[0])
    .appendQueryParameter(FORMAT_PARAM, "json")
    .appendQueryParameter(UNITS_PARAM, "metric")
    .appendQueryParameter(DAYS_PARAM, Integer.toString(7))
    .build();

At last

URL url = new URL(builtUri.toString());

Here is a full example comparing 2 fields in an object, one String and one int, also using Collator to sort.

public class Test {

    public static void main(String[] args) {

        Collator myCollator;
        myCollator = Collator.getInstance(Locale.US);

        List<Item> items = new ArrayList<Item>();

        items.add(new Item("costrels", 1039737, ""));
        items.add(new Item("Costs", 1570019, ""));
        items.add(new Item("costs", 310831, ""));
        items.add(new Item("costs", 310832, ""));

        Collections.sort(items, new Comparator<Item>() {
            @Override
            public int compare(final Item record1, final Item record2) {
                int c;
                //c = record1.item1.compareTo(record2.item1); //optional comparison without Collator                
                c = myCollator.compare(record1.item1, record2.item1);
                if (c == 0) 
                {
                    return record1.item2 < record2.item2 ? -1
                            :  record1.item2 > record2.item2 ? 1
                            : 0;
                }
                return c;
            }
        });     

        for (Item item : items)
        {
            System.out.println(item.item1);
            System.out.println(item.item2);
        }       

    }

    public static class Item
    {
        public String item1;
        public int item2;
        public String item3;

        public Item(String item1, int item2, String item3)
        {
            this.item1 = item1;
            this.item2 = item2;
            this.item3 = item3;
        }       
    }

}

Output:

costrels 1039737

costs 310831

costs 310832

Costs 1570019

This works in Python 2.x.

For Python 3 look in the docs:

import urllib.request

with urllib.request.urlopen("http://www.python.org") as url:
    s = url.read()
    # I'm guessing this would output the html source code ?
    print(s)

fldrDialog.SelectedPath = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory)

"If the SelectedPath property is set before showing the dialog box, the folder with this path will be the selected folder, as long as SelectedPath is set to an absolute path that is a subfolder of RootFolder (or more accurately, points to a subfolder of the shell namespace represented by RootFolder)."

MSDN - SelectedPath

"The GetFolderPath method returns the locations associated with this enumeration. The locations of these folders can have different values on different operating systems, the user can change some of the locations, and the locations are localized."

Re: Desktop vs DesktopDirectory

Desktop

"The logical Desktop rather than the physical file system location."

DesktopDirectory:

"The directory used to physically store file objects on the desktop. Do not confuse this directory with the desktop folder itself, which is a virtual folder."

MSDN - Special Folder Enum

MSDN - GetFolderPath

If there is no existing method then I guess you can iterate from 0 to input.size()/2, taking each consecutive element and appending it to a new ArrayList.

EDIT: Actually, I think you can take that List and use it to instantiate a new ArrayList using one of the ArrayList constructors.

You can just modified the .bash_profile by adding the MySQL $PATH as the following:
export PATH=$PATH:/usr/local/mysql/bin.

I did the following:

1- Open Terminal then $ nano .bash_profile or $ vim .bash_profile

2- Add the following PATH code to the .bash_profile

# Set architecture flags
export ARCHFLAGS="-arch x86_64"
# Ensure user-installed binaries take precedence
export PATH=/usr/local/mysql/bin:$PATH
# Load .bashrc if it exists
test -f ~/.bashrc && source ~/.bashrc 

3- Save the file.

4- Refresh Terminal using $ source ~/.bash_profile

5- To verify, type in Terminal $ mysql --version

6- It should print the output something like this:

$ mysql Ver 14.14 Distrib 5.7.17, for macos10.12 (x86_64)

The Terminal is now configured to read the MySQL commands from $PATH which is placed in the .bash_profile .

For more information about .scrollHeight property refer to the docs:

The Element.scrollHeight read-only attribute is a measurement of the height of an element's content, including content not visible on the screen due to overflow. The scrollHeight value is equal to the minimum clientHeight the element would require in order to fit all the content in the viewpoint without using a vertical scrollbar. It includes the element padding but not its margin.

Not possible, at least not in a reasonable amount of time.

The way this is often handled is a password "reset". That is, you give them a new (random) password and send them that in an email.

Also, using the awesome font, you can use the following tag. Simple and beautiful

With the possibility of changing the size and color and other features in CSS

It's a shortening for this:

notification.defaults = notification.defaults | Notification.DEFAULT_SOUND;

And | is a bit-wise OR.

Managed Code

Managed code is what Visual Basic .NET and C# compilers create. It runs on the CLR (Common Language Runtime), which, among other things, offers services like garbage collection, run-time type checking, and reference checking. So, think of it as, "My code is managed by the CLR."

Visual Basic and C# can only produce managed code, so, if you're writing an application in one of those languages you are writing an application managed by the CLR. If you are writing an application in Visual C++ .NET you can produce managed code if you like, but it's optional.

Unmanaged Code

Unmanaged code compiles straight to machine code. So, by that definition all code compiled by traditional C/C++ compilers is 'unmanaged code'. Also, since it compiles to machine code and not an intermediate language it is non-portable.

No free memory management or anything else the CLR provides.

Since you cannot create unmanaged code with Visual Basic or C#, in Visual Studio all unmanaged code is written in C/C++.

Mixing the two

Since Visual C++ can be compiled to either managed or unmanaged code it is possible to mix the two in the same application. This blurs the line between the two and complicates the definition, but it's worth mentioning just so you know that you can still have memory leaks if, for example, you're using a third party library with some badly written unmanaged code.

Here's an example I found by googling:

#using <mscorlib.dll>
using namespace System;

#include "stdio.h"

void ManagedFunction()
{
    printf("Hello, I'm managed in this section\n");
}

#pragma unmanaged
UnmanagedFunction()
{
    printf("Hello, I am unmanaged through the wonder of IJW!\n");
    ManagedFunction();
}

#pragma managed
int main()
{
    UnmanagedFunction();
    return 0;
}

A carriage return \r moves the cursor to the beginning of the current line. A newline \n causes a drop to the next line and possibly the beginning of the next line; That's the platform dependent part that Alexei notes above (on a *nix system \n gives you both a carriage return and a newline, in windows it doesn't)

What you use depends on what you're trying to do. If I wanted to make a little spinning thing on a console I would do str = "|\r/\r-\r\\\r"; for example.

In xml add

<ListView android:longClickable="true">

In java file

lv.setLongClickable(true) 

try this setOnItemLongClickListener()

lv.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
            @Override
            public boolean onItemLongClick(AdapterView<?> adapterView, View view, int pos, long l) {
                //final String category = "Position at : "+pos;
                final String category = ((TextView) view.findViewById(R.id.textView)).getText().toString();
                Toast.makeText(getActivity(),""+category,Toast.LENGTH_LONG).show();
                args = new Bundle();
                args.putString("category", category);
                return false;
            }
        });

This question has been answered already, but since there is a more convenient way to get the UNC path and some more I recommend using Path Copy, which is free and you can practically get any path you want with one click:

https://pathcopycopy.github.io/

Here is a screenshot demonstrating how it works. The latest version has more options and definitely UNC Path too:

Quoting MSDN:

When SET XACT_ABORT is ON, if a Transact-SQL statement raises a run-time error, the entire transaction is terminated and rolled back. When SET XACT_ABORT is OFF, in some cases only the Transact-SQL statement that raised the error is rolled back and the transaction continues processing.

In practice this means that some of the statements might fail, leaving the transaction 'partially completed', and there might be no sign of this failure for a caller.

A simple example:

INSERT INTO t1 VALUES (1/0)    
INSERT INTO t2 VALUES (1/1)    
SELECT 'Everything is fine'

This code would execute 'successfully' with XACT_ABORT OFF, and will terminate with an error with XACT_ABORT ON ('INSERT INTO t2' will not be executed, and a client application will raise an exception).

As a more flexible approach, you could check @@ERROR after each statement (old school), or use TRY...CATCH blocks (MSSQL2005+). Personally I prefer to set XACT_ABORT ON whenever there is no reason for some advanced error handling.

SHA stands for Secure Hash Algorithm while AES stands for Advanced Encryption Standard. So SHA is a suite of hashing algorithms. AES on the other hand is a cipher which is used to encrypt. SHA algorithms (SHA-1, SHA-256 etc...) will take an input and produce a digest (hash), this is typically used in a digital signing process (produce a hash of some bytes and sign with a private key).

Simple way

1. Create a new java class

   public class ActivityName extends FragmentActivity {
   @Override
    public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
       if (savedInstanceState == null){
       getSupportFragmentManager().beginTransaction()
               .add(android.R.id.content, new Fragment_name_which_you_wantto_open()).commit();}
    }
   }
   

2. in your activity where u want to call fragment

    Intent i = new Intent(Currentactivityname.this,ActivityName.class);
    startActivity(i);
   

Another Method

1. Place frame layout in your activity where u want to open fragment

     <FrameLayout
           android:id="@+id/frameLayout"
           android:layout_width="match_parent"
           android:layout_height="wrap_content">
       </FrameLayout>
   

2. Paste this code where u want to open fragment

       Fragment mFragment = null;
           mFragment = new Name_of_fragment_which_you_want_to_open();
           FragmentManager fragmentManager = getSupportFragmentManager();
           fragmentManager.beginTransaction()
                   .replace(R.id.frameLayout, mFragment).commit();
   

Here is working code for all android versions as of API LEVEL 26+ with backward compatibility.

 NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(getContext(), "M_CH_ID");

        notificationBuilder.setAutoCancel(true)
                .setDefaults(Notification.DEFAULT_ALL)
                .setWhen(System.currentTimeMillis())
                .setSmallIcon(R.drawable.ic_launcher)
                .setTicker("Hearty365")
                .setPriority(Notification.PRIORITY_MAX) // this is deprecated in API 26 but you can still use for below 26. check below update for 26 API
                .setContentTitle("Default notification")
                .setContentText("Lorem ipsum dolor sit amet, consectetur adipiscing elit.")
                .setContentInfo("Info");

NotificationManager notificationManager = (NotificationManager) getContext().getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(1, notificationBuilder.build());

UPDATE for API 26 to set Max priority

    NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    String NOTIFICATION_CHANNEL_ID = "my_channel_id_01";

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        NotificationChannel notificationChannel = new NotificationChannel(NOTIFICATION_CHANNEL_ID, "My Notifications", NotificationManager.IMPORTANCE_MAX);

        // Configure the notification channel.
        notificationChannel.setDescription("Channel description");
        notificationChannel.enableLights(true);
        notificationChannel.setLightColor(Color.RED);
        notificationChannel.setVibrationPattern(new long[]{0, 1000, 500, 1000});
        notificationChannel.enableVibration(true);
        notificationManager.createNotificationChannel(notificationChannel);
    }


    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID);

    notificationBuilder.setAutoCancel(true)
            .setDefaults(Notification.DEFAULT_ALL)
            .setWhen(System.currentTimeMillis())
            .setSmallIcon(R.drawable.ic_launcher)
            .setTicker("Hearty365")
       //     .setPriority(Notification.PRIORITY_MAX)
            .setContentTitle("Default notification")
            .setContentText("Lorem ipsum dolor sit amet, consectetur adipiscing elit.")
            .setContentInfo("Info");

    notificationManager.notify(/*notification id*/1, notificationBuilder.build());

Let's say you have the DLLs build for both platforms, and they are in the following location:

C:\whatever\x86\whatever.dll
C:\whatever\x64\whatever.dll

You simply need to edit your .csproj file from this:

<HintPath>C:\whatever\x86\whatever.dll</HintPath>

To this:

<HintPath>C:\whatever\$(Platform)\whatever.dll</HintPath>

You should then be able to build your project targeting both platforms, and MSBuild will look in the correct directory for the chosen platform.

Same issue on Fedora 23. I had to reinstall python3-pip to generate the proper pip3 folders in /usr/bin/.

sudo dnf reinstall python3-pip

I use this :

1-Declare a temp table variable in the script your building:

DECLARE @ShiftPeriodList TABLE(id INT NOT NULL);

2-Allocate to temp table:

IF (SOME CONDITION) 
BEGIN 
        INSERT INTO @ShiftPeriodList SELECT ShiftId FROM [hr].[tbl_WorkShift]
END
IF (SOME CONDITION2)
BEGIN
    INSERT INTO @ShiftPeriodList
        SELECT  ws.ShiftId
        FROM [hr].[tbl_WorkShift] ws
        WHERE ws.WorkShift = 'Weekend(VSD)' OR ws.WorkShift = 'Weekend(SDL)'

END

3-Reference the table when you need it in a WHERE statement :

INSERT INTO SomeTable WHERE ShiftPeriod IN (SELECT * FROM @ShiftPeriodList)

Try this code..

function (data) {


var json = jQuery.parseJSON(data);
alert( json.name );


}

I am just answering here with the formatted version of the final sql I needed based on Bob Jarvis answer as posted in my comment above:

select n1.name, n1.author_id, cast(count_1 as numeric)/total_count
  from (select id, name, author_id, count(1) as count_1
          from names
          group by id, name, author_id) n1
inner join (select author_id, count(1) as total_count
              from names
              group by author_id) n2
  on (n2.author_id = n1.author_id)

I want to clear here that preg_split(); is far away from it but explode(); can be used in similar way as split();

following is the comparison between split(); and explode(); usage

How was split() used

<?php

$date = "04/30/1973";
list($month, $day, $year) = split('[/.-]', $date);
echo $month; // foo
echo $day; // *
echo $year;

?>

URL: http://php.net/manual/en/function.split.php

How explode() can be used

<?php

$data = "04/30/1973";
list($month, $day, $year) = explode("/", $data);
echo $month; // foo
echo $day; // *
echo $year;

?>

URL: http://php.net/manual/en/function.explode.php

Here is how we can use it :)

using select-object for example:

Get-ADUser -Filter * -SearchBase 'OU=Users & Computers, DC=aaaaaaa, DC=com' -Properties DisplayName | select -expand displayname | Export-CSV "ADUsers.csv" 

Hope this will work for you!

You can use library(qpcR) for combining two matrix with unequal size.

resultant_matrix <- qpcR:::cbind.na(matrix1, matrix2)

NOTE:- The resultant matrix will be of size of matrix2.

Unless you call some function this is not at all trivial. (And, seriously, there's no real difference in complexity between calling printf and calling a win32 api function.)

Even DOS int 21h is really just a function call, even if its a different API.

If you want to do it without help you need to talk to your video hardware directly, likely writing bitmaps of the letters of "Hello world" into a framebuffer. Even then the video card is doing the work of translating those memory values into DisplayPort/HDMI/DVI/VGA signals.

Note that, really, none of this stuff all the way down to the hardware is any more interesting in ASM than in C. A "hello world" program boils down to a function call. One nice thing about ASM is that you can use any ABI you want fairly easily; you just need to know what that ABI is.

Just one line will be OK.

cat "`dirname $0`"/../some.txt

You should initialize yours recordings. You are passing to adapter null

ArrayList<String> recordings = null; //You are passing this null

In Your gradle.build file, Use this

"compile fileTree(dir: 'libs', include: ['*.jar'])"

And it works fine.

See my code

.float-left {_x000D_
    float:left;_x000D_
    width:300px; // or 33% for equal width independent of parent width_x000D_
}

<div>_x000D_
    <h2 align="center">San Andreas: Multiplayer</h2>_x000D_
    <div align="center" class="float-left">CONTENT OF COLUMN ONE GOES HERE</div>_x000D_
    <div align="center" class="float-left">CONTENT OF COLUMN TWO GOES HERE</div>_x000D_
    <div align="center" class="float-left">CONTENT OF COLUMN THREE GOES HERE</div>_x000D_
</div>

DATA = { u'spam': u'eggs', u'foo': frozenset([u'Gah!']), u'bar': { u'baz': 97 },
         u'list': [u'list', (True, u'Maybe'), set([u'and', u'a', u'set', 1])]}

def convert(data):
    if isinstance(data, basestring):
        return str(data)
    elif isinstance(data, collections.Mapping):
        return dict(map(convert, data.iteritems()))
    elif isinstance(data, collections.Iterable):
        return type(data)(map(convert, data))
    else:
        return data

print DATA
print convert(DATA)
# Prints:
# {u'list': [u'list', (True, u'Maybe'), set([u'and', u'a', u'set', 1])], u'foo': frozenset([u'Gah!']), u'bar': {u'baz': 97}, u'spam': u'eggs'}
# {'bar': {'baz': 97}, 'foo': frozenset(['Gah!']), 'list': ['list', (True, 'Maybe'), set(['and', 'a', 'set', 1])], 'spam': 'eggs'}

Assumptions:

• You've imported the collections module and can make use of the abstract base classes it provides
• You're happy to convert using the default encoding (use data.encode('utf-8') rather than str(data) if you need an explicit encoding).

If you need to support other container types, hopefully it's obvious how to follow the pattern and add cases for them.

For .NET DLLs you can use ildasm

According to http://blog.flameeyes.eu/2008/04/14/what-about-those-la-files, they're needed to handle dependencies. But using pkg-config may be a better option:

In a perfect world, every static library needing dependencies would have its own .pc file for pkg-config, and every package trying to statically link to that library would be using pkg-config --static to get the libraries to link to.

As claustrofob said, oninput is supported for IE9+.

However, "The oninput event is buggy in Internet Explorer 9. It is not fired when characters are deleted from a text field through the user interface only when characters are inserted. Although the onpropertychange event is supported in Internet Explorer 9, but similarly to the oninput event, it is also buggy, it is not fired on deletion.

Since characters can be deleted in several ways (Backspace and Delete keys, CTRL + X, Cut and Delete command in context menu), there is no good solution to detect all changes. If characters are deleted by the Delete command of the context menu, the modification cannot be detected in JavaScript in Internet Explorer 9."

I have good results binding to both input and keyup (and keydown, if you want it to fire in IE while holding down the Backspace key).

        combo1.DisplayMember = "Text";
        combo1.ValueMember = "Value";   
        combo1.Items.Add(new { Text = "someText"), Value = "someValue") });
        dynamic item = combo1.Items[combo1.SelectedIndex];
        var itemValue = item.Value;
        var itemText = item.Text;

Unfortunatly "combo1.SelectedValue" does not work, i did not want to bind my combobox with any source, so i came up with this solution. Maybe it will help someone.

You should also take a look at the at command in Windows. It will launch a program at a certain time in the background which works in this case.

Another option is to use the nssm service manager software. This will wrap whatever command you are running as a windows service.

UPDATE:

nssm isn't very good. You should instead look at WinSW project. https://github.com/kohsuke/winsw

This answer was written in 2011 from the point of view of what the Sun JDK of the time running on operating systems of the time actually did. That was a long time ago! leventov's answer offers a more up-to-date perspective.

That post is wrong, and nanoTime is safe. There's a comment on the post which links to a blog post by David Holmes, a realtime and concurrency guy at Sun. It says:

System.nanoTime() is implemented using the QueryPerformanceCounter/QueryPerformanceFrequency API [...] The default mechanism used by QPC is determined by the Hardware Abstraction layer(HAL) [...] This default changes not only across hardware but also across OS versions. For example Windows XP Service Pack 2 changed things to use the power management timer (PMTimer) rather than the processor timestamp-counter (TSC) due to problems with the TSC not being synchronized on different processors in SMP systems, and due the fact its frequency can vary (and hence its relationship to elapsed time) based on power-management settings.

So, on Windows, this was a problem up until WinXP SP2, but it isn't now.

I can't find a part II (or more) that talks about other platforms, but that article does include a remark that Linux has encountered and solved the same problem in the same way, with a link to the FAQ for clock_gettime(CLOCK_REALTIME), which says:

1. Is clock_gettime(CLOCK_REALTIME) consistent across all processors/cores? (Does arch matter? e.g. ppc, arm, x86, amd64, sparc).

It should or it's considered buggy.

However, on x86/x86_64, it is possible to see unsynced or variable freq TSCs cause time inconsistencies. 2.4 kernels really had no protection against this, and early 2.6 kernels didn't do too well here either. As of 2.6.18 and up the logic for detecting this is better and we'll usually fall back to a safe clocksource.

ppc always has a synced timebase, so that shouldn't be an issue.

So, if Holmes's link can be read as implying that nanoTime calls clock_gettime(CLOCK_REALTIME), then it's safe-ish as of kernel 2.6.18 on x86, and always on PowerPC (because IBM and Motorola, unlike Intel, actually know how to design microprocessors).

There's no mention of SPARC or Solaris, sadly. And of course, we have no idea what IBM JVMs do. But Sun JVMs on modern Windows and Linux get this right.

EDIT: This answer is based on the sources it cites. But i still worry that it might actually be completely wrong. Some more up-to-date information would be really valuable. I just came across to a link to a four year newer article about Linux's clocks which could be useful.

getDimensions(id) {
    var obj = questions.filter(function(node) {

    });

    return obj;   
}

URL-encoded payload must be provided on the body parameter of the http.NewRequest(method, urlStr string, body io.Reader) method, as a type that implements io.Reader interface.

Based on the sample code:

package main

import (
    "fmt"
    "net/http"
    "net/url"
    "strconv"
    "strings"
)

func main() {
    apiUrl := "https://api.com"
    resource := "/user/"
    data := url.Values{}
    data.Set("name", "foo")
    data.Set("surname", "bar")

    u, _ := url.ParseRequestURI(apiUrl)
    u.Path = resource
    urlStr := u.String() // "https://api.com/user/"

    client := &http.Client{}
    r, _ := http.NewRequest(http.MethodPost, urlStr, strings.NewReader(data.Encode())) // URL-encoded payload
    r.Header.Add("Authorization", "auth_token=\"XXXXXXX\"")
    r.Header.Add("Content-Type", "application/x-www-form-urlencoded")
    r.Header.Add("Content-Length", strconv.Itoa(len(data.Encode())))

    resp, _ := client.Do(r)
    fmt.Println(resp.Status)
}

resp.Status is 200 OK this way.

set global sql_mode="NO_BACKSLASH_ESCAPES,STRICT_TRANS_TABLE,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

This problem due to that you try to compile project that has the files of OLder SVN than you currently use.

You have two solutions to resolve this problem

1. to install the version 1.6 SVN to be compatible with project SVN files
2. try to upgrade the project ..( not always working ).

I had the same problem. It was because my JSON response contains some special characters and the server file was not encoded with UTF-8, so the Ajax call considered that this was not a valid JSON response.

Spring Security Documentation mentions the reason for blocking // in the request.

For example, it could contain path-traversal sequences (like /../) or multiple forward slashes (//) which could also cause pattern-matches to fail. Some containers normalize these out before performing the servlet mapping, but others don’t. To protect against issues like these, FilterChainProxy uses an HttpFirewall strategy to check and wrap the request. Un-normalized requests are automatically rejected by default, and path parameters and duplicate slashes are removed for matching purposes.

So there are two possible solutions -

1. remove double slash (preferred approach)
2. Allow // in Spring Security by customizing the StrictHttpFirewall using the below code.

Step 1 Create custom firewall that allows slash in URL.

@Bean
public HttpFirewall allowUrlEncodedSlashHttpFirewall() {
    StrictHttpFirewall firewall = new StrictHttpFirewall();
    firewall.setAllowUrlEncodedSlash(true);    
    return firewall;
}

Step 2 And then configure this bean in websecurity

@Override
public void configure(WebSecurity web) throws Exception {
    //@formatter:off
    super.configure(web);
    web.httpFirewall(allowUrlEncodedSlashHttpFirewall());
....
}

Step 2 is an optional step, Spring Boot just needs a bean to be declared of type HttpFirewall and it will auto-configure it in filter chain.

Spring Security 5.4 Update

In Spring security 5.4 and above (Spring Boot >= 2.4.0), we can get rid of too many logs complaining about the request rejected by creating the below bean.

import org.springframework.security.web.firewall.RequestRejectedHandler;
import org.springframework.security.web.firewall.HttpStatusRequestRejectedHandler;

@Bean
RequestRejectedHandler requestRejectedHandler() {
   return new HttpStatusRequestRejectedHandler();
}

If you want to use Win32 ports of some Unix utilities (rather than installing Cygwin), I recommend GNU utilities for Win32.

Lighter weight than Cygwin and more portable.

How you are running your script? If you did with

$ sh myscript

you should try:

$ bash myscript

or, if the script is executable:

$ ./myscript

sh and bash are two different shells. While in the first case you are passing your script as an argument to the sh interpreter, in the second case you decide on the very first line which interpreter will be used.

This works for me.

private OnClickListener mDisconnectListener;
mDisconnectListener = new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub

        }
    };

...

... onCreateView(...){

mButtonDisconnect = (Button) rootView.findViewById(R.id.button_disconnect);
mButtonDisconnect.setOnClickListener(mDisconnectListener);
...
}

What do I do wrong?

The source code of ToastDisplay is OK (mine is similar and works), but it will only receive something, if it is currently in foreground (you register receiver in onResume). But it can not receive anything if a different activity (in this case SendBroadcast activity) is shown.

Instead you probably want to startActivity ToastDisplay from the first activity?

BroadcastReceiver and Activity make sense in a different use case. In my application I need to receive notifications from a background GPS tracking service and show them in the activity (if the activity is in the foreground).

There is no need to register the receiver in the manifest. It would be even harmful in my use case - my receiver manipulates the UI of the activity and the UI would not be available during onReceive if the activity is not currently shown. Instead I register and unregister the receiver for activity in onResume and onPause as described in BroadcastReceiver documentation:

You can either dynamically register an instance of this class with Context.registerReceiver() or statically publish an implementation through the tag in your AndroidManifest.xml.

The following example creates a file chooser and displays it as first an open-file dialog and then as a save-file dialog:

String filename = File.separator+"tmp";
JFileChooser fc = new JFileChooser(new File(filename));

// Show open dialog; this method does not return until the dialog is closed
fc.showOpenDialog(frame);
File selFile = fc.getSelectedFile();

// Show save dialog; this method does not return until the dialog is closed
fc.showSaveDialog(frame);
selFile = fc.getSelectedFile();

Here is a more elaborate example that creates two buttons that create and show file chooser dialogs.

// This action creates and shows a modal open-file dialog.
public class OpenFileAction extends AbstractAction {
    JFrame frame;
    JFileChooser chooser;

    OpenFileAction(JFrame frame, JFileChooser chooser) {
        super("Open...");
        this.chooser = chooser;
        this.frame = frame;
    }

    public void actionPerformed(ActionEvent evt) {
        // Show dialog; this method does not return until dialog is closed
        chooser.showOpenDialog(frame);

        // Get the selected file
        File file = chooser.getSelectedFile();
    }
};

// This action creates and shows a modal save-file dialog.
public class SaveFileAction extends AbstractAction {
    JFileChooser chooser;
    JFrame frame;

    SaveFileAction(JFrame frame, JFileChooser chooser) {
        super("Save As...");
        this.chooser = chooser;
        this.frame = frame;
    }

    public void actionPerformed(ActionEvent evt) {
        // Show dialog; this method does not return until dialog is closed
        chooser.showSaveDialog(frame);

        // Get the selected file
        File file = chooser.getSelectedFile();
    }
};

To close your current window using JS, do this. First open the current window to trick your current tab into thinking it has been opened by a script. Then close it using window.close(). The below script should go into the parent window, not the child window. You could run this after running the script to open the child.

<script type="text/javascript">
    window.open('','_parent',''); 
    window.close();
</script>

function json2array(json){
    var result = [];
    var keys = Object.keys(json);
    keys.forEach(function(key){
        result.push(json[key]);
    });
    return result;
}

There is a new API called URLSearchParams in browsers which allow you to extract and change the values of the query string.

Currently, it seems to be supported in Firefox 44+, Chrome 49+ and Opera 36+.

Initialize/Input

To get started, create a new URLSearchParams object. For current implementations, you need to remove the "?" at the beginning of the query string, using slice(1) on the querystring, as Jake Archibald suggests:

var params = new URLSearchParams(window.location.search.slice(1)); // myParam=12

In later implementations, you should be able to use it without slice:

var params = new URLSearchParams(window.location.search); // myParam=12

Get

You can get params from it via the .get method:

params.get('myParam'); // 12

Set

Params can be changed using .set:

params.set('myParam', 'newValue');

Output

And if the current querystring is needed again, the .toString method provides it:

params.toString(); // myParam=newValue

There are a host of other methods in this API.

Polyfill

As browser support is still pretty thin, there is a small polyfill by Andrea Giammarchi (<3kB).

The parentheses are poorly placed.

You need to use:

doThrow(new Exception()).when(mockedObject).methodReturningVoid(...);
                                          ^

and NOT use:

doThrow(new Exception()).when(mockedObject.methodReturningVoid(...));
                                                                   ^

This is explained in the documentation

In my experience, default parameters seem cool at the time and make my laziness factor happy, but then down the road I'm using the class and I am surprised when the default kicks in. So I don't really think it's a good idea; better to have a className::className() and then a className::init(arglist). Just for that maintainability edge.

For apache look up SymLink or you can solve via the OS with Symbolic Links or on linux set up a library link/etc

My answer is one method specifically to windows 10.

So my method involves mapping a network drive to U:/ (e.g. I use G:/ for Google Drive)

open cmd and type hostname (example result: LAPTOP-G666P000, you could use your ip instead, but using a static hostname for identifying yourself makes more sense if your network stops)

Press Windows_key + E > right click 'This PC' > press N (It's Map Network drive, NOT add a network location)

If you are right clicking the shortcut on the desktop you need to press N then enter

Fill out U: or G: or Z: or whatever you want Example Address: \\LAPTOP-G666P000\c$\Users\username\

Then you can use <a href="file:///u:/2ndFile.html"><button type="submit">Local file</button> like in your question

related: You can also use this method for FTPs, and setup multiple drives for different relative paths on that same network.

related2: I have used http://localhost/c$ etc before on some WAMP/apache servers too before, you can use .htaccess for control/security but I recommend to not do so on a live/production machine -- or any other symlink documentroot example you can google

you can edit the javascrpit files dynamically in the Chrome debugger, under the Sources tab, however your changes will be lost if you refresh the page, to pause page loading before doing your changes, you will need to set a break point then reload the page and edit your changes and finally unpause the debugger to see your changes take effect.

Here's how I did it, in case it helps anyone:

In the config, I set a publicAccess attribute on the few routes that I want open to the public (like login or register):

$routeProvider
    .when('/', {
        templateUrl: 'views/home.html',
        controller: 'HomeCtrl'
    })
    .when('/login', {
        templateUrl: 'views/login.html',
        controller: 'LoginCtrl',
        publicAccess: true
    })

then in a run block, I set a listener on the $routeChangeStart event that redirects to '/login' unless the user has access or the route is publicly accessible:

angular.module('myModule').run(function($rootScope, $location, user, $route) {

    var routesOpenToPublic = [];
    angular.forEach($route.routes, function(route, path) {
        // push route onto routesOpenToPublic if it has a truthy publicAccess value
        route.publicAccess && (routesOpenToPublic.push(path));
    });

    $rootScope.$on('$routeChangeStart', function(event, nextLoc, currentLoc) {
        var closedToPublic = (-1 === routesOpenToPublic.indexOf($location.path()));
        if(closedToPublic && !user.isLoggedIn()) {
            $location.path('/login');
        }
    });
})

You could obviously change the condition from isLoggedIn to anything else... just showing another way to do it.

It simple with apply function in R

f <- apply(f,2,toupper)

No need to check if the column is character or any other type.

You simply need to add that line legend: { display: false }

The following code will wait for completion of all calculations and return exit status 1 if any of doCalculations fails.

#!/bin/bash
for i in $(seq 0 9); do
   (doCalculations $i >&2 & wait %1; echo $?) &
done | grep -qv 0 && exit 1

One thing one needs to keep in mind about the storage is the as-if rule. The compiler is not required to put a variable in a specific place - instead it can place it wherever it pleases for as long as the compiled program behaves as if it were run in the abstract C machine according to the rules of the abstract C machine. This applies to all storage durations. For example:

• a variable that is not accessed all can be eliminated completely - it has no storage... anywhere. Example - see how there is 42 in the generated assembly code but no sign of 404.
• a variable with automatic storage duration that does not have its address taken need not be stored in memory at all. An example would be a loop variable.
• a variable that is const or effectively const need not be in memory. Example - the compiler can prove that foo is effectively const and inlines its use into the code. bar has external linkage and the compiler cannot prove that it would not be changed outside the current module, hence it is not inlined.
• an object allocated with malloc need not reside in memory allocated from heap! Example - notice how the code does not have a call to malloc and neither is the value 42 ever stored in memory, it is kept in a register!
• thus an object that has been allocated by malloc and the reference is lost without deallocating the object with free need not leak memory...
• the object allocated by malloc need not be within the heap below the program break (sbrk(0)) on Unixen...

Here's an extension for an in-place occurrences replace method on String, that doesn't no an unnecessary copy and do everything in place:

extension String {
    mutating func replaceOccurrences<Target: StringProtocol, Replacement: StringProtocol>(of target: Target, with replacement: Replacement, options: String.CompareOptions = [], locale: Locale? = nil) {
        var range: Range<Index>?
        repeat {
            range = self.range(of: target, options: options, range: range.map { self.index($0.lowerBound, offsetBy: replacement.count)..<self.endIndex }, locale: locale)
            if let range = range {
                self.replaceSubrange(range, with: replacement)
            }
        } while range != nil
    }
}

(The method signature also mimics the signature of the built-in String.replacingOccurrences() method)

May be used in the following way:

var string = "this is a string"
string.replaceOccurrences(of: " ", with: "_")
print(string) // "this_is_a_string"

You should set responseType: ResponseContentType.Blob in your GET-Request settings, because so you can get your image as blob and convert it later da base64-encoded source. You code above is not good. If you would like to do this correctly, then create separate service to get images from API. Beacuse it ism't good to call HTTP-Request in components.

Here is an working example:

Create image.service.ts and put following code:

Angular 4:

getImage(imageUrl: string): Observable<File> {
    return this.http
        .get(imageUrl, { responseType: ResponseContentType.Blob })
        .map((res: Response) => res.blob());
}

Angular 5+:

getImage(imageUrl: string): Observable<Blob> {
  return this.httpClient.get(imageUrl, { responseType: 'blob' });
}

Important: Since Angular 5+ you should use the new HttpClient.

The new HttpClient returns JSON by default. If you need other response type, so you can specify that by setting responseType: 'blob'. Read more about that here.

Now you need to create some function in your image.component.ts to get image and show it in html.

For creating an image from Blob you need to use JavaScript's FileReader. Here is function which creates new FileReader and listen to FileReader's load-Event. As result this function returns base64-encoded image, which you can use in img src-attribute:

imageToShow: any;

createImageFromBlob(image: Blob) {
   let reader = new FileReader();
   reader.addEventListener("load", () => {
      this.imageToShow = reader.result;
   }, false);

   if (image) {
      reader.readAsDataURL(image);
   }
}

Now you should use your created ImageService to get image from api. You should to subscribe to data and give this data to createImageFromBlob-function. Here is an example function:

getImageFromService() {
      this.isImageLoading = true;
      this.imageService.getImage(yourImageUrl).subscribe(data => {
        this.createImageFromBlob(data);
        this.isImageLoading = false;
      }, error => {
        this.isImageLoading = false;
        console.log(error);
      });
}

Now you can use your imageToShow-variable in HTML template like this:

<img [src]="imageToShow"
     alt="Place image title"
     *ngIf="!isImageLoading; else noImageFound">
<ng-template #noImageFound>
     <img src="fallbackImage.png" alt="Fallbackimage">
</ng-template>

I hope this description is clear to understand and you can use it in your project.

See the working example for Angular 5+ here.

The problem is this block:

using (var sr = new StreamReader(ms))
{
    Console.WriteLine(sr.ReadToEnd());                        
}

When the StreamReader is closed (after leaving the using), it closes it's underlying stream as well, so now the MemoryStream is closed. When the StreamWriter gets closed, it tries to flush everything to the MemoryStream, but it is closed.

You should consider not putting the StreamReader in a using block.
