• SL4: Root element is missing

  - by Number8

  Hello, I know this has been asked elsewhere, but none of the questions or answers helped. I open an xml file in my SL 4 app: StreamResouceInfo sri = Application.GetResourceStream(new System.Uri("z.xml", UriKind.Relative)); if (null != sri) { XDocument xDoc = XDocument.Load(sri.Stream); } "Root element is missing" exception. The xml: Hmm, can't seem to post the xml... It is well-formed and valid, with a single root node and all tags closed. Thanks for any hints...

• Spring Transaction Manager

  - by cedric

  Hi. I have a j2ee application running on spring framework. I am implementing a transaction manager with AOP. It works fine. When an exception occurs in my method it is detected by my AOP configuration and rolls back the changes in the DB. But the problem is the code where you expect the error should not be surrounded with try-catch. When I suround it with try-catch it won't roll-back. But I need to do some stuffs like logging whenever there are errors and the only place I can think of placing it is in the catch block.

• How do I access a asp.net session variable from APP_CODE??

  - by user313714

  I have seen lots of posts here and elsewhere stating that one can access session variables from app_code. I want to access an already created session. this code errors out because of a null exception. string myFile = HttpContext.Current.Session["UploadedFile"]; this creates a null session variable. System.Web.SessionState.HttpSessionState Session = HttpContext.Current.Session; It looks like I can create a new session variable but not access an already created one. Anyone have any idea what might be giving me problems?

• calling webservice in java servlet

  - by Pravin

  I have created a servlet which displays a form having some fields and a submit button and also created a web service having methods which are needed in my servlet. I have deployed the web service on Tomcat 5.5.9/Axis and servlet web application on Tomcat ( same instance of Tomcat) using eclipse.

• how subsonic SP should return a value

  - by android.sm

  Hi all, I'm very much new to SubSonic and need a little guidance. Here, I want to know how my SP should return a value. Currently, when I execute it I simply pass an Int and it returns me a string value. Here is code: SubSonic SP: public static StoredProcedure GetQuote(int? CategoryId) { StoredProcedure sp = new StoredProcedure("GetQuote", DataService.GetInstance("Quotes Provider"), "dbo"); sp.Command.AddParameter("@CategoryId", CategoryId, DbType.Int32, 0, 10); return sp; } My Code: public bool GetQuote(int category, out string quote) { bool val = false; quote = ""; try { StoredProcedure sp = SPs.GetQuote(category); if (sp != null) { sp.Execute(); val = true; } } catch (Exception err) { throw err; } return val; } Thanks all

• How do you add a row to a databound datagridview using the datagridview in the gui?

  - by IsaacB

  Hi guys, I've bound a datagridview to a collection of objects. It's giving me a null reference exception when I try to add a new row to a collection (empty or otherwise) using the gui. More specifically, when there is a write event it does this. How can I override the behavior of the write event and manually add all of the columns contents to the object collection? I could disable the add new row feature and make an add button, but the built in datagridview row add looks so much more slick.

• Yield only as many are required from a generator

  - by Matt Joiner

  I wish to yield from a generator only as many items are required. In the following code a, b, c = itertools.count() I receive this exception: ValueError: too many values to unpack I've seen several related questions, however I have zero interest in the remaining items from the generator, I only wish to receive as many as I ask for, without providing that quantity in advance. It seems to me that Python determines the number of items you want, but then proceeds to try to read and store more than that number. How can I yield only as many items as I require, without passing in how many items I want?

• Template error with django-photologue: 'Permission Denied'

  - by Ellie P.

  I'm in the process of re-setting up my Django development environment after reinstalling my OS. We use django-photologue with our project, which I installed using easy_install. However, I'm getting a template error on every template that has a photologue photo: TemplateSyntaxError at /newsroom/news/ Caught an exception while rendering: (13, 'Permission denied') One example of the line where the error is located: <img src="{{ photo.get_list_url }}"> I'm totally stumped--I've used photologue for this project on many different platforms and have never had this problem. Google yields nothing. I'm currently using Jolicloud (based on Ubuntu Jaunty). I'm working with a pre-existing database, so all of the photo sizes and everything have already been set up.

• Limit Connections with semaphores

  - by Robert

  I'm trying to limit the number of connections my server will accept using semaphores, but when running, my code doesn't seem to make this restriction - am I using the semaphore correctly? eg. I have hardcoded the number of permit as 2, but I can connect an unlimited number of clients... public class EServer implements Runnable { private ServerSocket serverSocket; private int numberofConnections = 0; private Semaphore sem = new Semaphore(2); private volatile boolean keepProcessing = true; public EServer(int port) throws IOException { serverSocket = new ServerSocket(port); } @Override public void run() { while (keepProcessing) { try { sem.acquire(); Socket socket = serverSocket.accept(); process(socket, getNextConnectionNumber()); } catch (Exception e) { } finally { sem.release(); } } closeIgnoringException(serverSocket); } private synchronized int getNextConnectionNumber() { return ++numberofConnections; } // processing related methods }

Where is the value that appears in the text box of the richfaces calendar component?

• How to use Visual Studio debugger visualizers built against a different framework version?

  - by michielvoo

  I compiled the ExpressionTreeVisualizer project found in the Visual Studio 2010 samples but when I try to use it in a .NET 3.5 project I get the exception below: Could not load file or assembly 'file:///C:\Program Files (x86)\Microsoft\Visual Studio 2010\Common7\Packages\Debugger\Visualizers\ExpressionTreeVisualizer.dll' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded. The sample project had the TargetFrameworkVersion set to v4.0 and after changing it to v3.5 and building it now works in my project. I changed the source code and project file and rebuilt it so that I now have two expression tree visualizers, one for v3.5 projects and one for v4.0 projects. Is there a better way? Thanks!

  - by DavidDev

  Hi! I have a NSManagedObject subclass named Tour. I stored the reference to it using this code: prefs = [NSUserDefaults standardUserDefaults]; NSURL *myURL = [[myTour objectID] URIRepresentation]; NSData *uriData = [NSKeyedArchiver archivedDataWithRootObject:myURL]; [prefs setObject:uriData forKey:@"tour"]; Now I want to retrieve it. I tried using: NSData *myData = [prefs objectForKey:@"tour"]; NSURL *myURL = [NSKeyedUnarchiver unarchiveObjectWithData:myData]; TourAppDelegate *appDelegate = (TourAppDelegate *)[[UIApplication sharedApplication] delegate]; NSManagedObjectID *myID = [appDelegate.persistentStoreCoordinator managedObjectIDForURIRepresentation:myURL]; if (myID) { Tour *tempObject = [appDelegate.managedObjectContext objectWithID:myID]; //WARNING tour = tempObject; } if (tour) //instruction... But it's giving me this warning "Incompatible Objective-c types.

• Send Logcat output of an App to an EmailAdress

  - by Sebi

  Hi Were now testing our application with a few friends. Sometimes there are some errors which dont throw an exception. So I don't really know whats the problem was. So i thought it would be a good idea to implement a menu item which allows to send the logcat file to a email adress, so that we can examine the logcat. Unfortunately I didnt found a hint in the Internet how to extract the Logcat from a phone. How to send a email shouldn't be the problem.

• how to disable web page cache throughout the servlets

  - by Kurt

  To no-cache web page, in the java controller servlet, I did somthing like this in a method: public ModelAndView home(HttpServletRequest request, HttpServletResponse response) throws Exception { ModelAndView mav = new ModelAndView(ViewConstants.MV_MAIN_HOME); mav.addObject("testing", "Test this string"); mav.addObject(request); response.setHeader("Cache-Control", "no-cache, no-store"); response.setHeader("Pragma", "no-cache"); response.setDateHeader("Expires", 0); return mav; } But this only works for a particular response object. I have many similar methods in a servlet. And I have many servlets too. If I want to disable cache throughout the application, what should I do? (I do not want to add above code for every single response object) Thanks in advance.

• iPad crashes that aren't happening on iPhone or iPod Touch

  - by alyoshak

  Has anyone had difficulty getting what has otherwise been a solid iPhone app working on the iPad? I was under the impression that iPhone apps would run without problems on the iPad. We are are experiencing crashes (not intermittent - same place, at same time) that we've never gotten on the iPhone or iPod Touch. I have become suspicious that the crashes are memory-management related, but even if so, why only on the iPad? 2010-05-17 10:19:06.474 ASSIST[82:207] *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<UISectionRowData 0x6041480> valueForUndefinedKey:]: this class is not key value coding-compliant for the key deliveryDate.' 2010-05-17 10:19:06.481 ASSIST[82:207] Stack: ( 852041337, 861292157, 852040861, 850755255, 850750995, 850758945, 81279, 123007, 126693, 149141, 851599725, 827486573, 827486477, 827486431, 827485745, 827487359, 827454123, 851903137, 851590065, 851588321, 819339483, 819339655, 827151561, 827144691, 9461, 9324 ) terminate called after throwing an instance of 'NSException' Program received signal: “SIGABRT”.

• C# getting version of unmanaged dll

  I'm calling an unmanaged dll from my managed c# code and wanted to check I'm calling the right version. The code I'm trying to load the assembly (to then get the resource file and then get the version) is: cur_version = Assembly.LoadFile("X:\Workspace\yreceipts_pos\yRprintProcessor\Debug\yRprintProcessor.dll"); It's failing because of this error: The module was expected to contain an assembly manifest. (Exception from HRESULT: 0x80131018) Does anyone know how to get around this or have a better way to check the version of an unmanaged dll from managed c# code? Thanks in advance, Richard
