  • Some animation requests in a Silverlight application

    - by Mohit Deshpande
    I am making a flash card application. It shows the question and then a textbox for user input, all wrapped in a border or rectangle. So what I want is an animation that "flips" the rectangle or border upside-down and then their is text on the "back". Also, I want my application to APPEAR transition from one card to another by "flying off" the screen then "another" card comes in to replace the other one in the opposite direction. But actually I'm want just a little animation of the border or rectangle moving off the screen then coming back in, but in the opposite direction.

  • IHttpAsyncHandler and IObservable web requests

    - by McLovin
    Within Async handler I'm creating an IObservable from webrequest which returns a redirect string. I'm subscribing to that observable and calling AsyncResult.CompleteCall() but I'm forced to use Thread.Sleep(100) in order to get it executed. And it doesn't work every time. I'm pretty sure this is not correct. Could you please shine some light. Thank you! public IAsyncResult BeginProcessRequest(HttpContext context, AsyncCallback cb, object state) { _context = context; _ar = new AsyncResult(cb, state); _tweet = context.Request["tweet"]; string url = context.Request["url"]; if(String.IsNullOrEmpty(_tweet) || String.IsNullOrEmpty(url)) { DisplayError("<h2>Tweet or url cannot be empty</h2>"); return _ar; } _oAuth = new oAuthTwitterRx(); using (_oAuth.AuthorizationLinkGet().Subscribe(p => { _context.Response.Redirect(p); _ar.CompleteCall(); }, exception => DisplayError("<h2>Unable to connect to twitter, please try again</h2>") )) return _ar; } public class AsyncResult : IAsyncResult { private AsyncCallback _cb; private object _state; private ManualResetEvent _event; private bool _completed = false; private object _lock = new object(); public AsyncResult(AsyncCallback cb, object state) { _cb = cb; _state = state; } public Object AsyncState { get { return _state; } } public bool CompletedSynchronously { get { return false; } } public bool IsCompleted { get { return _completed; } } public WaitHandle AsyncWaitHandle { get { lock (_lock) { if (_event == null) _event = new ManualResetEvent(IsCompleted); return _event; } } } public void CompleteCall() { lock (_lock) { _completed = true; if (_event != null) _event.Set(); } if (_cb != null) _cb(this); } }

  • Access control for cross site requests in Internet Explorer

    - by Aleksandar
    I am trying to make an AJAX call from several domains to a single one which will handle the request. Enabling Cross domain in Firefox and Chrome was easy by setting the header on the handling server: header("Access-Control-Allow-Origin: *"); But this doesn't help enabling it in Internet Explorer. When I try: httpreq.send(''); it stops with error Access denied. How can this be enabled in Internet Explorer?

  • MINA: Performing synchronous write requests / read responses

    - by Matt Huggins
    I'm attempting to perform a synchronous write/read in a demux-based client application with MINA 2.0 RC1, but it seems to get stuck. Here is my code: public boolean login(final String username, final String password) { // block inbound messages session.getConfig().setUseReadOperation(true); // send the login request final LoginRequest loginRequest = new LoginRequest(username, password); final WriteFuture writeFuture = session.write(loginRequest); writeFuture.awaitUninterruptibly(); if (writeFuture.getException() != null) { session.getConfig().setUseReadOperation(true); return false; } // retrieve the login response final ReadFuture readFuture = session.read(); readFuture.awaitUninterruptibly(); if (readFuture.getException() != null) { session.getConfig().setUseReadOperation(true); return false; } // stop blocking inbound messages session.getConfig().setUseReadOperation(false); // determine if the login info provided was valid final LoginResponse loginResponse = (LoginResponse)readFuture.getMessage(); return loginResponse.getSuccess(); } I can see on the server side that the LoginRequest object is retrieved, and a LoginResponse message is sent. On the client side, the DemuxingProtocolCodecFactory receives the response, but after throwing in some logging, I can see that the client gets stuck on the call to readFuture.awaitUninterruptibly(). I can't for the life of me figure out why it is stuck here based upon my own code. I properly set the read operation to true on the session config, meaning that messages should be blocked. However, it seems as if the message no longer exists by time I try to read response messages synchronously. Any clues as to why this won't work for me?

  • Setting the content-type of requests performed by jQuery jqGrid

    - by Nigel
    I am using the latest version of jqGrid: 3.6.4 This seems like a simple problem (or at least it did before I spent a few hours on it): When the grid sends a request to the server (to a controller action), its content-type is always: application/x-www-form-urlencoded; charset=UTF-8 and I would like it to be: application/json; charset=utf-8 but I can find no way of setting the content-type (there is no contentType option as you would find on a $.ajax call for example). So just to clarify, I am not asking how to set the content-type on a jQuery server request, but specifically using jqGrid, which does not provide an obvious option for doing this. Thanks, Nigel.

  • Rails 2.3.11 Server Crashing After 4 Requests

    - by Taka
    I have a Rails 2.3.11 application running on my local Windows machine using InstantRails. I cd to my application directory, run ruby script/server to start the server running, and point my browser to localhost:3000. I get the page I expect, and am able to click a few links to other pages (all of them are static). The problem starts when I load the 4th page or so. My server crashes, with this message: Processing HomeController#index (for 127.0.0.1 at 2012-06-23 15:48:40) [GET] Rendering template within layouts/application Rendering home/index Completed in 11ms (View: 9, DB: 1) | 200 OK [http://localhost/index] C:/rails/ruby/lib/ruby/gems/1.8/gems/activesupport-2.3.11/lib/active_support/memoizable.rb:46: [BUG] Segmentation fault ruby 1.8.7 (2012-02-08 patchlevel 358) [i386-mingw32] This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information. I've uninstalled this gem and reinstalled it, which didn't help. It doesn't seem to be the gem though, because the segmentation fault sometimes occurs in C:/rails/ruby/lib/ruby/gems/1.8/gems/mongrel-1.1.2-x86-mswin32/lib/mongrel.rb:114 or C:/rails/ruby/lib/ruby/1.8/benchmark.rb:306 Versions: >ruby -v ruby 1.8.7 (2012-02-08 patchlevel 358) [i386-mingw32] >rails -v Rails 2.3.11 I'd like to get this fixed so while I'm developing I don't have to keep restarting my server. Any suggestions?

  • asp:Login control requests

    - by Dean
    Hi All, ran into an issue, we are using webforms with a site with this dir structure: root: / secure : /securepages/ we only want users who are logged in to access /securepages/. currently we are using the login control, 3.5, forms auth, all is working ok but know we have thrown assl cert into the mix and the issue is that the login control is requesting WebResource.axd?d=XukT0PE1PS-iOKw3RT8Z6g2&t=633834231612265882 from the non secure url e.g. ht tp://www.mysite.com/WebResource.axd?d=XukT0PE1PS-iOKw3RT8Z6g2&t=633834231612265882 . This causes the browser to prompt the user to download unsecure content. I am using some redirecting in the global.asax to handle redirection to https://xx xxxlogin.aspx if login.aspx it requested from http://. thanks

  • How to cache queries in Rails across multiple requests

    - by m.u.sheikh
    I want to cache query results so that the same results are fetched "for more than one request" till i invalidate the cache. For instance, I want to render a sidebar which has all the pages of a book, much like the index of a book. As i want to show it on every page of the book, I have to load it on every request. I can cache the rendered sidebar index using action caching, but i also want to actually cache the the query results which are used to generate the html for the sidebar. Does Rails provide a way to do it? How can i do it?

  • Detecting Requests from Mobile Browsers in ASP.NET

    - by Josh Stodola
    I have an existing web site and I would like to create a mobile version of it that is more suitable. For instance, the main site uses drop-down menus and we all know those are quite the fail on mobile devices. I would like to redirect to my mobile version (it will be a subdomain of the current site) if I detect a request from a mobile browser. So when they Google something and come to my site, they will automatically see the mobile version (just like Wikipedia). Does ASP.NET provide an easy way of doing this? If not, how can I do it?

  • Dealing with ISO-encoding in AJAX requests (prototype)

    - by acme
    I have a HTML-page, that's encoded in ISO-8859-1 and a Prototype-AJAX call that's build like this: new Ajax.Request('api.jsp', { method: 'get', parameters: {...}, onSuccess: function(transport) { var ajaxResponse = transport.responseJSON; alert(ajaxResponse.msg); } }); The api.jsp returns its data in ISO-8859-1. The response contains special characters (German Umlauts) that are not displayed correctly, even if I add a "encoding: ISO-8895-1" to the AJAX-request. Does anyone know how to fix this? If I call api.jsp in a new browser window separately the special characters are also corrupt. And I can't get any information about the used encoding in the response header. The response header looks like this: Server Apache-Coyote/1.1 Content-Type application/json Content-Length 208 Date Thu, 29 Apr 2010 14:40:24 GMT Notice: Please don't advice the usage of UTF-8. I have to deal with ISO-8859-1.

  • In what order does DOJO handles ajax requests?

    - by mm2887
    Hi, Using a form in a dialog box I am using Dojo in jsp to save the form in my database. After that request is completed using dojo.xhrPost() I am sending in another request to update a dropdown box that should include the added form object that was just saved, but for some reason the request to update the dropdown is executed before saving the form in the database even though the form save is called first. Using Firebug I can see that the getLocations() request is completed before the sendForm() request. This is the code: Add Team sendForm("ajaxResult1", "addTeamForm"); dijit.byId("addTeamDialog").hide(); getLocations("locationsTeam"); </script> function sendForm(target, form){ var targetNode = dojo.byId(target); var xhrArgs = { form: form, url: "ajax", handleAs: "text", load: function(data) { targetNode.innerHTML = data; }, error: function(error) { targetNode.innerHTML = "An unexpected error occurred: " + error; } } //Call the asynchronous xhrGet var deferred = dojo.xhrPost(xhrArgs); } function getLocations(id) { var targetNode = dojo.byId(id); var xhrArgs = { url: "ajax", handleAs: "text", content: { location: "yes" }, load: function(data) { targetNode.innerHTML = data; }, error: function(error) { targetNode.innerHTML = "An unexpected error occurred: " + error; } } //Call the asynchronous xhrGet var deferred = dojo.xhrGet(xhrArgs); } Why is this happening? Is there way to make the first request complete first before the second executes? To reduce the possibilities of why this is happening I tried setting the cache property in xhrGet to false but the result is still the same. Please help!

This is connected to the firewall. Because when I turn off the firewall, the port is open. So this is not a problem with my modem. Do I need the firewall? The broadband modem has a hardware firewall. Update: Forgot to add. When my firewall is inactive, it closes ports after a time. So when I use linuxdc, I have to flush iptabels and activating it again. Is this supposed to do this when the firewall is deactivated? Update again: All my ports are closed now, flushing the iptable does not work anymore. I have uninstalled gufw, but still all my ports are closed. And to say it again, this has nothing to do with my broadband modem since it worked when I used windows 7. I need help to open the ports.

  • sIFR and multiple requests

    - by mblaze
    Hi! I've been using sIRF for a while but it was the first time I watch the traffic between the client and the server. There is only one file for sIRF, nyala.swf. I am using replacements for some headings, at most 5 or 6 at a time on one page. I can see from firebug the a separate request is going to server for the same swf file. I think I saw a config option to change this behavior but I couldn't find it again. Any ideas?

  • jQuery.ajax(): discard slow requests

    - by Thomas
    I've build a livesearch with the jQuery.ajax() method. On every keyup events it receives new result data from the server. The problem is, when I'm typing very fast, e.g. "foobar" and the GET request of "fooba" requires more time than the "foobar" request, the results of "fooba" are shown. To handle this with the timeout parameter is impossible, I think. Has anyone an idea how to solve this?
