• What's the best way to cancel an asynchronous WCF request?

  - by Pwninstein

  (Assuming a WCF method called "MyFunction") Currently, to support canceling a WCF request, I'm using the BeginMyFunction/EndMyFunction methods generated by svcutil (and handling an isCanceled flag when dispatching the results to the main thread). I'd like to use the MyFunctionAsync method (and hooking into MyFunctionAsyncCompleted event instead) for async calls instead of Begin/End. What is the best/supported way to handle canceling WCF requests if using MyFunctionAsyncCompleted, and still ensuring that the event doesn't get fired on a page that's no longer loaded (i.e. page navigation within a frame). Thanks!

But in that onclick method, my A activity haves to do some work before start B, and B also haves to do some work because it haves to load a lot of data for the UI. I need a PD that is viewed by the user in all the process of the loading data of changin from activity A to B. ¿how can do it? i tryed storing a static ProgressDialog on MyApplication.java, and with these methods: public static void showProgressDialog(Context c) { pd = ProgressDialog.show(c, c.getResources().getString(R.string.app_name), c.getResources().getString(R.string.loading), true, false); } public static void dismissProgressDialog(){ pd.dismiss(); } but it doesn't works, it doesn't shows nothing, i dont know why how to achieve this by a easy way? i know that i can do it with async task, but that is too hard for me, i can't understand the code examples i am finding on this web and google code examples are welcome thanks

  - by black sensei

  Hello Experts! i'm trying to create an application which connects to internet and consume web services for every of it's operation.As far as i'm concerned i'll like to useasync method which i'm using already to get a collection of Contacts.I've realized that when i'm doing the same for groups (meaning getting groups async) i'm having errors in the calls , but when using normal call there ins't.So i did some research online and find that a lot of people has the same problem. Some of them are asked to use WCF (for which i don't know jack).I'll like to know if there is another way to overcome this. if not can somebody point me to reliable resource online and help me get through it? thanks for reading and helping

• Why a thread is aborted in ASP.NET MVC (again)?

  - by Dario Solera

  Here is what I do in a controller action: create and start a new Thread that does a relatively long processing task (~30 seconds on average, but might be several minutes) immediately return the page response so the user knows processing has started (trivially, a Json with a task ID for polling purposes). At some random point, ThreadAbortException is thrown, so the async task does not complete. The exception is not thrown every time, it just happens randomly roughly 25% of the times. Points to note: I'm not calling Response.End or Response.Redirect - there isn't even a request running when the exception is thrown I tried using ThreadPool and I got the same behavior I know running threads in ASP.NET has several caveats but I don't care right now Any suggestion?

• How to set variable before callback is called?

  - by user1995327

  I'm trying to design a webpage... I have a function that I call get all info needed for an idividuals home page. A snippet of the codes is: exports.getHomePageData = function(userId, cb) { var pageData = {}; pageData.userFullName = dbUtil.findNameByUserId(userId, function(err){ if (err) cb(err); }); pageData.classes = dbUtil.findUserClassesByUserId(userId, function(err){ if (err) cb(err); }); cb(pageData); } The problem I'm having is the cb(pageData) is being called before I even finish setting the elements. I've seen that people use the async library to solve this but I was wondering if there was any other way for me to do it without needing more modules... Thanks!

• Page not rendering until BackgroundWorker.RunWorkerAsync completes

  - by brainimus

  I have an aspx page that on a button click creates a BackgroundWorker and then calls the RunWorkerAsync method. In my aspx file I have set Async='true' but when I run the application and click the button it appears as though the page waits to refresh until the processing of the BackgroundWorker is done. How do I get control to return to the page (and have the page refresh) after the BackgroundWorker is created and started? BackgroundWorker worker = new BackgroundWorker(); worker.DoWork += RunJob; worker.RunWorkerCompleted += JobCompleted; worker.RunWorkerAsync();

• AIO network sockets and zero-copy under Linux

  - by remyhorton

  I have been experimenting with async Linux network sockets (aio_read et al in aio.h/librt), and one thing i have been trying to find out is whether these are zero-copy or not. Pretty much all i have read so far discusses file I/O, whereas its network I/O i am interested in. AIO is a bit of a pain to use and i suspect is non-portable, so wondering whether its worth persevering with it. Zero-copy is just about the only advantage (albiet a major one for my purposes) it would have over (non-blocking) select/epoll..

• How to get the id of Updatepanel which initiated a postback

  - by Voice

  Hi I need to intercept server callback after udate panel async post back and determine which panel initiated the request. The code is pretty simple: Sys.WebForms.PageRequestManager.getInstance().add_pageLoaded(InterceptUpdateCallback); function InterceptUpdateCallback(sender, args) { var updatedPanels = args.get_panelsUpdated(); for (idx = 0; idx < updatedPanels.length; idx++) { if (updatedPanels[idx].id == "myUpdatePanel") { StartSmth(); break; } } } And it works when UpdatePanel is not inside another UpdatePanel. But when it is inside another UpdatePanel updatedPanels[idx].id has parent Updatepanel id. So how can I get the id of UpdatePanel which initiated the request (the inner UpdatePanel)? Thanx

• Multi-threaded downloader in C# question

  - by blez

  Currently I have multi-threaded downloader class that uses HttpWebRequest/Response. All works fine, it's super fast, BUT.. the problem is that the data needs to be streamed while it's downloading to another app. That means that it must be streamed in the right order, the first chunk first, and then the next in the queue. Currently my downloader class is sync and Download() returns byte[]. In my async multi-threaded class I make for example, list with 4 empty elements (for slots) and I pass each index of the slot to each thread using the Download() function. That simulates synchronization, but that's not what I need. How should I do the queue thing, to make sure the data is streamed as soon as the first chunk start downloading.

• Returning the html from .ajax call

  - by coffeeaddict

  I'm getting undefined for some reason when I try to return the html via the callback function: function getDataFromUrl(urlWithContent) { // jQuery async request $.ajax( { url: urlWithContent, dataType: "html", success: function(data) { return $('.result').html(data); }, error: function(e) { alert('Error: ' + e); } }); } I know I'm getting data back, I see it in firebug in the response and also when I alert out the data, I see the entire page content come up in the alert box. When I call my function, I am doing the following: var divContent = getDataFromUrl(dialogDiv.attr("href")); if(divContent) dialogDiv.innerHTML = divContent; when I alert out the divContent (before the if statement) I'm getting undefined. Maybe I'm just going about this wrong on how I'm returning back the data? I also tried just return data; same thing, I get undefined after the call to this method when set to my variable.

• Memory leak till crash due to HttpRequest

  - by Alex R.

  I played with HttpRequest and realized that the memory is not cleaned up after any request. After some time the running tab within Chrome will crash. Here is some testing code. Put a large sized file into the 'www' directory and set the URL in the code accordingly. import 'dart:async'; import 'dart:html'; void main() { const PATH = "http://127.0.0.1:3030/PATH_TO_FILE"; new Timer.periodic(new Duration(seconds:10), (Timer it)=>getString(PATH)); } void getString( String url){ HttpRequest.getString(url).then((String data){ }); } Is this really a bug or did I something wrong?

• $.ajax working with Firefox, not IE

  - by Isamtron

  Hello, I have a jQuery code to allow users to login using a lightbox (http://colorpowered.com/colorbox/) and immediately start downloading files, without being redirected or having the page reloaded.

• How can I get my div id to reload via ajax and jquery

  - by Matt Nathanson

  I'm creating a CMS using jQuery and AJAX. When I click, my "Add Campaign" buttom, it creates a unique client ID in the DB and on a hard reload, the new client shows up in its container. I am trying to use ajax to reload the container on the fly and I'm not having the exact luck i am hoping for. I can get it to reload, but it's like it's pulling in descriptions of each of the clients as well! function AddNewClient() { dataToLoad = 'clientID=' + clientID + '&addClient=yes'; $.ajax({ type: 'post', url: '/clients/controller.php', datatype: 'html', data: dataToLoad, target: ('#clientssidebar'), async: false, success: function(html){ $('#clientssidebar').html(html); }, error: function() { alert('An error occured!'); } }); };

• alternatives to eval for running remote code.

  - by Raynos

  Are there any alternatives to using eval to immediatly run remote & trusted javascript code. function load(filePath) { var o = $.ajax({ url: filePath, dataType: 'html', async: false }); eval(o.responseText); } load("somePath"); // run a function that relies on the code from o.responseText being loaded doSomethingWithCode(); I'm aware that synchronous loading of javascript is adviced againts. But if there is no choice are there any cross browser alternatives for the use of eval above. [Edit] To clarify in more detail the code being loaded is a self executing function. Which needs to execute before doSomethingWidthCode. It's also being loaded from the server on the same domain hence its trusted.

• jQuery wait for ajax call to be over before continuing

  - by Flo

  Hi all, I have a problem with a jQuery ajax call. I need to wait for the call to be finished in order to return a value. However, the script seems to jump ahead and not wait for the call to be over. my function then returns "undefined". I have tried to use the .ajax() method and set the value of async to false, but this would not work either. I could I get my function to return the value that I could through the ajax call? Thank you! Here is the code: function get_rsrce_name(){ jQuery.post( '<?php echo admin_url( 'admin-ajax.php' ); ?>', { action :'my_action', option_rsrce : 'option_rsrce' }, function( data ) { output = data.option_name; }, "json" ); return output; }

• Can't echo jquery (with ajax) variable in php

  - by Lars Kerff

  I'm trying to post a variable through ajax. But it won't echo the variable in php. This are the variables (these are working, seen in the log): $("#slider").bind("valuesChanged", function(e, data){console.log("min: " + data.values.min + " max: " + data.values.max);}); The Ajax part: $("#slider").bind("valuesChanged", function (e, data) { $.ajax({ type: "POST", dataType: "text", url: "../test.php", data: { minValue: data.values.min, maxValue: data.values.max }, async: false, success: function(data){ alert('yeah') }, error: function(xhr) { alert('fail') // if your PHP script return an erroneous header, you'll land here } }); }); </script> And php echo: <?php if ( $_POST ) { echo $_POST[ 'minValue' ]; } ?> Now why does it not echo the post? Thanks!

• What happens to a transaction when App Pool recycles or the worker process is terminated forcefully?

  - by ARS

  The architecture of the application is straight forward. There is a web application which maintain account holder data. This data is processed and the status of account holders is updated based on number of business rules. This process is initiated using a button on the page and is a long running process (say 15 mins). A component is developed to do this data processing which internally calls stored procedures. Most of the business rules are kept in stored procedure. To handle timeouts the processing is done asynchornously(using Thread Pool or custom thread or Async Callback Delegates). The entire process run under a transaction. I would like to know your view on what happens to the transaction if the app pool is recycled or the worker process is terminated forcefully?

• How to tell iPhone NSURLConnection to abort

  - by Jahmic

  I have an app that makes moderate use of NSURLConnection. These async calls eventually finish and release properly (it looks like), but sometimes it takes some time for them to finish. So, there are times when I exit the app, (note, not just sending it the background), that some of these connections are still active. If I immediately restart the app, the app freezes on startup. (didFinishLaunchingWithOptions never seems to get called). While I'm not certain these connections are the issue, it would probably be good to terminate or cancel any remaining. Any suggestions on how to do this? Bonus points on how to debug the restart also. (I'm already saving NSLog statements to a downloadable file)

• Wait for function to finish before executing the rest

  - by Wurlitzer

  When the user refreshes the page, defaultView() is called, which loads some UI elements. $.address.change() should execute when defaultView() has finished, but this doesn't happen all the time. $.address.change() cannot be in the success: callback, as it's used by the application to track URL changes. defaultView(); function defaultView() { $('#tout').fadeOut('normal', function() { $.ajax({ url: "functions.php", type: "GET", data: "defaultview=true", async: false, success: function (response) { $('#tout').html(response).fadeIn('normal'); } }); }); } $.address.change(function(hash) { hash = hash.value; getPage(hash); }); I'm at a loss as to how to make $.address.change() wait for defaultView() to finish. Any help would be appreciated.

• ASP.NET web site running in IIS and hosting WCF service fails to get connections on the TCP server

  - by Salil

  I am using the combination of Silverlight client application along with ASP.NET web site running in IIS and hosting WCF service. This WCF service uses the library that starts a TCP server and and initiates requests to the connected TCP clients when the silverlight client application makes the WCF async requests. When I use this library in a local WPF application, the TCP server is able to receive client connection requests and I can get info from these clients. But when I use the same library from the implementation of the WCF service inside the ASP .NET web site project (+ Silverlight client), the server strangely does not receive any connection requests i.e. when I create TcpListener object and issue a start, nothing happens (nor an exception is generated). My setup is I am using the Ethernet for the Internet and Wi-Fi for the TCP clients. Is the WCF service getting confused because of this? Is there any special WCF settings I should put in for TcpListener.Start to work?
