  • How to handle client disconnect with PollingDuplexHttpBinding

    - by sako73
    I am implementing a WCF service, with a Silverlight 3 client, which uses a PollingDuplexHttpBinding for communications. What are the alternatives for handling when a client closes their browser without disconnecting from the server first? I know that it will eventually throw a TimeoutException, which I can catch, but is there a better way of detecting this? Thanks.

  • Fact or fiction: Webkit’s rendering performance is much lower when used in Qt

    - by Jen
    Using Qt’s Webkit implementation renders much slower than directly implementing the Webkit engine -- is this true or just a myth? From my own experience, I found the load time of a complex page about twice as long in Qt’s “Fancy Browser” example as it does in Google Chrome (which also incorporates a port of Webkit), but I hardly think that is a fair comparison. Any insights on this?

  • Is it really necessary to have a competely validated Mark Up and css for SEO purposes

    - by Hitesh Manchanda

    - by Joey V.
    Trying to mirror a local intranet site and have found previous questions using 'wget'.

    hi people, i just want an Action to print a barcode image, but i can´t get this working in MVC, i just do the following: public function barcodeAction() { $this->_helper->layout->disableLayout(); $this->_helper->viewRenderer->setNoRender(); Zend_Barcode::render($_GET['barcodeType'], 'image', $_GET, $_GET); } but when I call /barcode?barcodeType=code39&text=ZEND-FRAMEWORK I just obtain: "The image couldn't be displayed because it has errors" (or something like that, browser-dependant).

  • TinyMCE is glitchy in IE8

    - by Force Flow
    I'm using the jQuery version of TinyMCE 3.3.9.3 In firefox, it works fine (10 sec video depicting it in use): http://www.youtube.com/watch?v=TrAE0igfT3I In IE8 (in IE8 standards mode), I can't type or click any buttons. However, if I use ctrl+v to paste, then I can start typing, but the buttons still don't work (a 45 sec video depicting it in use): http://www.youtube.com/watch?v=iBSRlE8D8F4 The jQuery TinyMCE demo on TinyMCE's site works for me in IE8. Here's the init code: $().ready(function(){ function tinymce_focus(){ $('.defaultSkin table.mceLayout').css({'border-color' : '#6478D7'}); $('.defaultSkin table.mceLayout tr.mceFirst td').css({'border-top-color' : '#6478D7'}); $('.defaultSkin table.mceLayout tr.mceLast td').css({'border-bottom-color' : '#6478D7'}); } function tinymce_blur(){ $('.defaultSkin table.mceLayout').css({'border-color' : '#93a6e1'}); $('.defaultSkin table.mceLayout tr.mceFirst td').css({'border-top-color' : '#93a6e1'}); $('.defaultSkin table.mceLayout tr.mceLast td').css({'border-bottom-color' : '#93a6e1'}); } $('textarea.tinymce').tinymce({ script_url : 'JS/tinymce/tiny_mce.js', theme : "advanced", mode : "exact", theme : "advanced", invalid_elements : "b,i,iframe,font,input,textarea,select,button,form,fieldset,legend,script,noscript,object,embed,table,img,a,h1,h2,h3,h4,h5,h6", //theme options theme_advanced_buttons1 : "cut,copy,paste,pastetext,pasteword,selectall,|,undo,redo,|,cleanup,removeformat,|", theme_advanced_buttons2 : "bold,italic,underline,|,bullist,numlist,|,forecolor,backcolor,|", theme_advanced_buttons3 : "", theme_advanced_buttons4 : "", theme_advanced_toolbar_location : "top", theme_advanced_toolbar_align : "left", theme_advanced_statusbar_location : "none", theme_advanced_resizing : false, //plugins plugins : "inlinepopups,paste", dialog_type : "modal", paste_auto_cleanup_on_paste : true, setup: function(ed){ ed.onInit.add(function(ed){ //check for addEventListener -- primarily supported by firefox only var edDoc = ed.getDoc(); if ("addEventListener" in edDoc){ edDoc.addEventListener("focus", function(){ tinymce_focus(); }, false); edDoc.addEventListener("blur", function(){ tinymce_blur(); }, false); } }); } }); }); Any ideas as to why it's not working in IE8?

  • Streaming Video with Blackberry Simulator

    - by Jenny
    So, I wrote a quick little app for the iphone that takes in an http URL, and plays the .mp4 video located at that URL (it does more than that, of course, but that's the meat of it). Naturally, I wanted to have it on more than just a single mobile platform, so I decided to target Blackberry next. However, I'm running into a lot of problems with the Blackberry Environment. First of all, I learn that I can only download 256k files! I learn how to set that variable in my MDS simulator (and learn that this is NOT a production solution, because any end users will have to have their BES or MDS admin change the setting there). Then, I find a video less than 2 MB I can practice with. Going to the browser prompts me to save the video (rather than it playing in the browser like I expected). After saving the video, it refuses to play, saying it's the wrong format. So. I can't find a reference to IF Blackberry can stream with HTTP (i"ve heard it CAN use RTSP, though, and heard some rumors that it can't use HTTP, which would really suck). I also can't find a reference to what format blackberry uses (although I can find a million programs that will convert one file to the 'blackberry' format). Surely SOMEONE must have tried to stream video with the blackberry before. How did they go about doing so? Is it just a hopeless pipedream? Will I have to go with RTSP? Sorry for the lack of a concrete question...I'm just really lost, and I hate how so many tutorials or forum posts seem to assume I know the capabilities of the Blackberry... Edit: I finally found out that the .3gp (which I'd never heard of ) format is what Blackberry uses. Still have no idea how to stream videos off the web, though. I found a tutorial: http://www.blackberry.com/knowledgecenterpublic/livelink.exe/fetch/2000/348583/800332/1089414/How%5FTo%5F-%5FPlay%5Fvideo%5Fwithin%5Fa%5FBlackBerry%5Fsmartphone%5Fapplication.html?nodeid=1383173&vernum=0 That seemed to be useful, but the code doesn't work if you give it a URL (even though it claims it does).

  • HTML APIs for touch devices?

    - by askvictor
    What HTML APIs are available for touch screen devices (e.g. tablet PCs)? I notice that GMail's iPad interface (and other mobile interfaces) doesn't scroll down in a normal web browser (pretending to be an iPad via a user-agent hack). How can one access this API on a PC? I have a school full of tablet PCs that aren't wonderful in tablet mode due to lack of application support, but there looks to be an increasing number of web-based apps that will fill this gap.

  • Silverlight OOB Application Path Portability

    - by jws
    Silverlight Out-of-browser applications get installed to a seemingly random location: AppData\LocalLow\Microsoft\Silverlight\OutOfBrowser\2333572144.www.microsoft.com for example. Currently, I am simply storing this path, which works perfectly well on a single machine and a single install, but how can I refer to this application between different installations?

  • Monotouch serialize UIImage

    - by cvista
    Hi I need to cache images locally and was thinking about saving them as SerializableDictionary SerializableDictionary is from: http://weblogs.asp.net/pwelter34/archive/2006/05/03/444961.aspx I was wondering if this was a: a good way of handling caching of images (for offline mode - the data is constantly updated so pulls from the web first). b: how can i do this? I seem to be only left with the following xml: <?xml version="1.0" encoding="us-ascii"?> <dictionary> <item> <key> <string>http://img.theguidestar.com/thumb/491520.png</string> </key> <value> <UIImage xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <Handle /> <Size> <Width>0</Width> <Height>0</Height> </Size> </UIImage> </value> </item> </dictionary> Is there anything specific i should be doing to make it serialize the image itself? w://

  • jQuery .load() XHTML issue

    - by Urfe
    I am having some strange problems loading content from another XHTML page via jQuery. When the second page I try to load from is served as XHTML I get the below error. I don't know if it helps but both documents validate when I get the error. Uncaught Error: NO_MODIFICATION_ALLOWED_ERR: DOM Exception 7 Currently the header on the second page I load from is: <?xml version="1.0" encoding="iso-8859-1" ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <meta name="language" content="en" /> <title>some title</title> <!-- CSS & Javascript included here --> </head> The content type is set as: application/xhtml+xml;charset=iso-8859-1 Interestingly, when I remove all the XHTML stuff from the header and stop setting the content type the error does not occur and everything works great. The load process currently looks like the below. It works fine when everything is plain HTML. $('#overpage').find(".wrap").load(this.getTrigger().attr("href")+" #op").show(); I'm curious why the process only does not work when the second page I load from is XHTML. I don't want to serve the page as just plain HTML and am looking for advice on what I am doing wrong. Both pages validate and I'm really scratching my head here. Many thanks!

  • Hide overflow in Silverlight TextBox

    - by chrisbz
    I have a Silverlight TextBox control that is inside of a Grid column with the width set to 'Auto', so the TexBox's width expands/contracts with the browser window is resized. Unfortunately, when the number of characters entered into the textbox exceeds the textbox's width, the textbox grows to accommodate it. Are there any properties that can be applied to the textbox that will force it to not expand with the number of characters inside of it? Thanks.

  • Some questions about writing on ASP.NET response stream

    - by vtortola
    Hi, I'm making tests with ASP.NET HttpHandler for download a file writting directly on the response stream, and I'm not pretty sure about the way I'm doing it. This is a example method, in the future the file could be stored in a BLOB in the database: public void GetFile(HttpResponse response) { String fileName = "example.iso"; response.ClearHeaders(); response.ClearContent(); response.ContentType = "application/octet-stream"; response.AppendHeader("Content-Disposition", "attachment; filename=" + fileName); using (FileStream fs = new FileStream(Path.Combine(HttpContext.Current.Server.MapPath("~/App_Data"), fileName), FileMode.Open)) { Byte[] buffer = new Byte[4096]; Int32 readed = 0; while ((readed = fs.Read(buffer, 0, buffer.Length)) > 0) { response.OutputStream.Write(buffer, 0, readed); response.Flush(); } } } But, I'm not sure if this is correct or there is a better way to do it. My questions are: When I open the url with the browser, appears the "Save File" dialog... but it seems like the server has started already to push data into the stream before I click "Save", is that normal? If I remove the line"response.Flush()", when I open the url with the browser, ... I see how the web server is pushing data but the "Save File" dialog doesn't come up, (or at least not in a reasonable time fashion) why? When I open the url with a WebRequest object, I see that the HttpResponse.ContentLength is "-1", although I can read the stream and get the file. What is the meaning of -1? When is HttpResponse.ContentLength going to show the length of the response? For example, I have a method that retrieves a big xml compresed with deflate as a binary stream, but in that case... when I access it with a WebRequest, in the HttpResponse I can actually see the ContentLength with the length of the stream, why? What is the optimal length for the Byte[] array that I use as buffer for optimal performance in a web server? I've read that is between 4K and 8K... but which factors should I consider to make the correct decision. Does this method bloat the IIS or client memory usage? or is it actually buffering the transference correctly? Sorry for so many questions, I'm pretty new in web development :P Cheers.
