• Silverlight Socket Constantly Returns With Empty Buffer

  - by Benny

  I am using Silverlight to interact with a proxy application that I have developed but, without the proxy sending a message to the Silverlight application, it executes the receive completed handler with an empty buffer ('\0's). Is there something I'm doing wrong? It is causing a major memory leak. this._rawBuffer = new Byte[this.BUFFER_SIZE]; SocketAsyncEventArgs receiveArgs = new SocketAsyncEventArgs(); receiveArgs.SetBuffer(_rawBuffer, 0, _rawBuffer.Length); receiveArgs.Completed += new EventHandler<SocketAsyncEventArgs>(ReceiveComplete); this._client.ReceiveAsync(receiveArgs); if (args.SocketError == SocketError.Success && args.LastOperation == SocketAsyncOperation.Receive) { // Read the current bytes from the stream buffer int bytesRecieved = this._client.ReceiveBufferSize; // If there are bytes to process else the connection is lost if (bytesRecieved > 0) { try { //Find out what we just received string messagePart = UTF8Encoding.UTF8.GetString(_rawBuffer, 0, _rawBuffer.GetLength(0)); //Take out any trailing empty characters from the message messagePart = messagePart.Replace('\0'.ToString(), ""); //Concatenate our current message with any leftovers from previous receipts string fullMessage = _theRest + messagePart; int seperator; //While the index of the seperator (LINE_END defined & initiated as private member) while ((seperator = fullMessage.IndexOf((char)Messages.MessageSeperator.Terminator)) > 0) { //Pull out the first message available (up to the seperator index string message = fullMessage.Substring(0, seperator); //Queue up our new message _messageQueue.Enqueue(message); //Take out our line end character fullMessage = fullMessage.Remove(0, seperator + 1); } //Save whatever was NOT a full message to the private variable used to store the rest _theRest = fullMessage; //Empty the queue of messages if there are any while (this._messageQueue.Count > 0) { ... } } catch (Exception e) { throw e; } // Wait for a new message if (this._isClosing != true) Receive(); } } Thanks in advance.

• Simple web general localization/translation backend (using mysql)?

  - by Hendrik

  Hi is there a free avaible translation backend with database avaible which can handle multiple users(no login needed), multiple languages (UTF-8) and provides automatic google translation? I just need this tool to fill a database (preferable mysql) with simple tables like this: language | label | text english | _helloworld | Hello World! german | _helloworld | Hallo Welt! I don't care about export since this will have to be created anyways.. Thanks it would be a real timesaver if something with an usable UI exists already.

• How is the order of execution for HttpModules determined?

  - by jessegavin

  Suppose that both FirstModule and SecondModule handle the Application_BeginRequest event. Will it execute in the order defined in the web.config? <httpModules> <add type="MyApp.FirstModule, MyApp" name="FirstModule"/> <add type="MyApp.SecondModule, MyApp" name="SecondModule"/> <add type="OtherApp.OtherModule, OtherApp" name="OtherModule"/> </httpModules> Are there other ways that the order can be specified?

• Silverlight WinDg Memory Release Issue

  - by Chris Newton

  Hi, I have used WinDbg succesfully on a number of occasions to track down and fix memory leaks (or more accurately the CLRs inability to garbage collect a released object), but am stuck with one particular control. The control is displayed within a child window and when the window is closed a reference to the control remains and cannot be garbage collected. I have resolved what I believe to be the majority of the issues that could have caused the leak, but the !gcroot of the affected object is not clear (to me at least) as to what is still holding on to this object. The ouput is always the same regardless of the content being presented in the child window: DOMAIN(03FB7238):HANDLE(Pinned):79b12f8:Root: 06704260(System.Object[])- 05719f00(System.Collections.Generic.Dictionary2[[System.IntPtr, mscorlib],[System.Object, mscorlib]])-> 067c1310(System.Collections.Generic.Dictionary2+Entry[[System.IntPtr, mscorlib],[System.Object, mscorlib]][])- 064d42b0(System.Windows.Controls.Grid)- 064d4314(System.Collections.Generic.Dictionary2[[MS.Internal.IManagedPeerBase, System.Windows],[System.Object, mscorlib]])-> 064d4360(System.Collections.Generic.Dictionary2+Entry[[MS.Internal.IManagedPeerBase, System.Windows],[System.Object, mscorlib]][])- 064d3860(System.Windows.Controls.Border)- 064d4218(System.Collections.Generic.Dictionary2[[MS.Internal.IManagedPeerBase, System.Windows],[System.Object, mscorlib]])-> 064d4264(System.Collections.Generic.Dictionary2+Entry[[MS.Internal.IManagedPeerBase, System.Windows],[System.Object, mscorlib]][])- 064d3bfc(System.Windows.Controls.ContentPresenter)- 064d3d64(System.Collections.Generic.Dictionary2[[MS.Internal.IManagedPeerBase, System.Windows],[System.Object, mscorlib]])-> 064d3db0(System.Collections.Generic.Dictionary2+Entry[[MS.Internal.IManagedPeerBase, System.Windows],[System.Object, mscorlib]][])- 064d3dec(System.Collections.Generic.Dictionary2[[System.UInt32, mscorlib],[System.Windows.DependencyObject, System.Windows]])-> 064d3e38(System.Collections.Generic.Dictionary2+Entry[[System.UInt32, mscorlib],[System.Windows.DependencyObject, System.Windows]][])- 06490b04(Insurer.Analytics.SharedResources.Controls.HistoricalKPIViewerControl) If anyone has any ideas about what could potentially be the problem, or if you require more information, please let me know.

• C check before writing to closed pipe

  - by Gary

  Is there an easy way to check if a pipe is closed before writing to it in C? I have a child and parent process, and the parent has a pipe to write to the child. However, if the child closes the pipe and the parent tries to read - I get a broken pipe error. So how can I check to make sure I can write to the pipe, so I can handle it as an error if I can't? Thanks!

• How to make a ToolStripComboBox to fill all the space available on a ToolStrip?

  - by Ivan

  A ToolStripComboBox is placed after a ToolStripButton and is folowed by another one, which is right-aligned. How do I best set up the ToolStripComboBox to always adjust its length to fill all the space available between the preceeding and the folowing ToolStripButtons? In past I used to handle a parent resize event, calculate the new length to set based on neighboring elements coordinates and setting the new size. But now, as I am developing a new application, I wonder if there is no better way.

• Why are there multiple ajaxtoolkit libraries, 1 per language?

  - by George

  I don't have much experience in making app multi lingual, but it seems to me that you don't need a separate dll for each language that you want to handle. Could someone speculate why the toolkit was designed this way?

• Myself throwing NullReferenceException... needs help

  - by Amit Ranjan

  I know it might be a weird question and its Title too, but i need your help. I am a .net dev , working on platform for the last 1.5 years. I am bit confused on the term usually we say " A Good Programmer ". I dont know ,what are the qualities of a good programmer ? Is the guy who writes a bug free code? or Can develop applications solely? or blah blah blah...lots of points. I dont know... But as far i am concerned , I know I am not a good programmer, still in learning phase an needs a lot to learn in coming days. So you guys are requested to please help me with this two problems of mine My first problem is regarding the proper Error Handling, which is a most debatable aspect of programming. We all know we use ` try { } catch { } finally { } ` in our code to manage exception. But even if I use try { } catch(exception ex) { throw ex } finally { } , different guys have different views. I still dont know the good way to handle errors. I can write code, use try-catch but still i feel I lacks something. When I saw the codes generated by .net fx tools even they uses throw ex or `throw new Exception("this is my exception")`.. I am just wondering what will be the best way to achieve the above. All means the same thing but why we avoid something. If it has some demerits then it must be made obselete.Anyways I still dont have one [how to handle errors efficiently?]. I generally follow the try-catch(execoption ex){throw ex}, and usually got stucked in debates with leads why you follow this why not that... 2.Converting your entire code blocks in modules using Design patterns of some OOPs concepts. How do you guys decide what architeture or pattern will be the best for my upcoming application based on its working, flow etc. I need to know what you guys can see that I can't. Since I know , I dont have that much experience but I can say, with my experience that experience doesnot comes either from degree/certificates or success you made instead it cames from failures you faced or got stucking situations. Pleas help me out.

• Java configuration framework

  - by Steen

  I'm in the process of weeding out all hardcoded values in a java library and was wondering what framework would be the best (in terms of zero- or close-to-zero configuration) to handle run-time configuration? I would prefer xml-based config-files, but it's not essential. Please do only reply if you have practical experience with a framework. I'm not looking for examples, but experience... Thanks for taking the time.

• Displaying Flex Object References

  - by Pie21

  I have a bit of a memory leak issue in my Flex application, and the short version of my question is: is there any way (in AcitonScript 3) to find all live references to a given object? What I have is a number of views with presentation models behind each of them (using Swiz). The views of interest are children of a TabNavigator, so when I close the tab, the view is removed from the stage. When the view is removed from the stage, Swiz sets the model reference in the view to null, as it should. I also removeAllChildren() from the view. However when profiling the application, when I do this and run a GC, neither the view nor the presentation model are freed (though both set their references to each other to null). One model object used by the view (not a presenter, though) IS freed, so it's not completely broken. I've only just started profiling today (firmly believing in not optimising too early), so I imagine there's some kind of reference floating around somewhere, but I can't see where, and what would be super helpful would be the ability to debug and see a list of objects that reference the target object. Is this at all possible, and if not natively, is there some light-weight way to code this into future apps for debugging purposes? Cheers.

• Xcode preferences across multiple computers?

  - by Martytoof

  I run Xcode on both my laptop and desktop. I'm constantly tweaking my setup with regards to key bindings. Rather than try to get both configurations identical by hand, is there any way to create the configuration on one computer and then share it via dropbox (for example) for the other to use? Perhaps by symlinking the laptop's configuration file to one stored on dropbox? Very curious how others handle this situation.

• How to pick a chunksize for python multiprocessing with large datasets

  - by Sandro

  I am attempting to to use python to gain some performance on a task that can be highly parallelized using http://docs.python.org/library/multiprocessing. When looking at their library they say to use chunk size for very long iterables. Now, my iterable is not long, one of the dicts that it contains is huge: ~100000 entries, with tuples as keys and numpy arrays for values. How would I set the chunksize to handle this and how can I transfer this data quickly? Thank you.

• Find a free X11 display number

  - by James

  I have some unit tests that need an X11 display so I plan to start Xvfb before running them, but to start Xvfb I will need a free display number to connect it to. My best guess is to see what's free in /tmp/.X11-unix but I'm not sure how to handle the race if many tests try to start simultaneously. sshd must do this, does anyone know how?
