  • Exceptions by DataContext

    - by Bas
    I've been doing some searching on the internet, but I can't seem to find the awnser. What exceptions can a DataContext throw? Or to be more specific, what exceptions does the DataContext.SubmitChanges() method throw?

  • What's the standard behaviour for an out parameter when a TryXxxx method returns false?

    - by Matt Lacey
    Assuming a method with the following signature bool TryXxxx(object something, out int toReturn) What is it acceptable for toReturn to be if TryXxxx returns false? In that it's infered that toReturn should never be used if TryXxxx fails does it matter? If toReturn was a nulable type, then it would make sense to return null. But int isn't nullable and I don't want to have to force it to be. If toReturn is always a certain value if TryXxxx fails we risk having the position where 2 values could be considered to indicate the same thing. I can see this leading to potential possible confusion if the 'default' value was returned as a valid response (when TryXxxx returns true). From an implementation point if view it looks like having toReturn be a[ny] value is easiest, but is there anything more important to consider?

  • GORM "getNextException" equivalent

    - by Josh K
    GORM sits on top of [Hibernate](http://en.wikipedia.org/wiki/Hibernate_(Java). The issue is that sometimes Hibernate will throw exceptions from the JDBC driver that I can't figure out how to investigate. Specifically: Could not execute JDBC batch update; /* snip */ Caused by: java.sql.BatchUpdateException: /* snip */ [insert] was aborted. Call getNextException to see the cause. If it makes any difference I'm using PostgreSQL.

  • How to pass content in response from Exception filter in Asp.net WebAPI?

    - by jaffa
    Consider following code: My problem is: 1) I can't seem to cast the errors to HttpContent 2) I can't use the CreateContent extension method as this doesn't exist on the context.Response.Content.CreateContent public class ServiceLayerExceptionFilter : ExceptionFilterAttribute { public override void OnException(HttpActionExecutedContext context) { if (context.Response == null) { var exception = context.Exception as ModelValidationException; if ( exception != null ) { var modelState = new ModelStateDictionary(); modelState.AddModelError(exception.Key, exception.Description); var errors = modelState.SelectMany(x => x.Value.Errors).Select(x => x.ErrorMessage); // Cannot cast errors to HttpContent?? // var resp = new HttpResponseMessage(HttpStatusCode.BadRequest) {Content = errors}; // throw new HttpResponseException(resp); // Cannot create response from extension method?? //context.Response.Content.CreateContent } else { context.Response = new HttpResponseMessage(context.Exception.ConvertToHttpStatus()); } } base.OnException(context); } }

    what is a best practice in cases such as this one: try { // do something } catch (SpecificException ex) { Response.Redirect("~/InformUserAboutAn/InternalException/"); } the warning i get is that ex is never used. however all i need here is to inform the user, so i don't have a need for it. do i just do: try { // do something } catch { Response.Redirect("~/InformUserAboutAn/InternalException/"); } somehow i don't like that, seems strange!!? any tips? best practices? what would be the way to handle this. thnx

  • Castle windsor security exception

    - by Sunil
    I developed a small WCF service that uses Castle Windsor IoC container and it works fine on my PC. When I deploy it onto a Win 2008 R2 server and host the WCF service in IIS 7 it fails with the following error. I checked the server level web.config and the trust level is set to "Full". What do I need to do to get this to work. As a test I deployed the same service as it is onto a Windows 2003 server with the trust level set to "Full" and it works fine. I am unable to figure out what setting/configuration I am missing on the 2008 server that is making the service fail. Stack Trace: [SecurityException: That assembly does not allow partially trusted callers.] Castle.Windsor.WindsorContainer..ctor() +0 WMS.ServiceContractImplementation.IoC.IoCInstanceProvider..ctor(Type serviceType) in D:\WCF\WCFProofOfConcept\WMSServices \WMS.ServiceContractImplementation\IoC\IoCInstanceProvider.cs:19 WMS.ServiceContractImplementation.IoC.IoCServiceBehavior.ApplyDispatchBehav­ior(ServiceDescription serviceDescription, ServiceHostBase serviceHostBase) in D:\WCF \WCFProofOfConcept\WMSServices\WMS.ServiceContractImplementation\IoC \IoCServiceBehavior.cs:24 System.ServiceModel.Description.DispatcherBuilder.InitializeServiceHost(Ser­viceDescription description, ServiceHostBase serviceHost) +377 System.ServiceModel.ServiceHostBase.InitializeRuntime() +37 System.ServiceModel.ServiceHostBase.OnBeginOpen() +27 System.ServiceModel.ServiceHostBase.OnOpen(TimeSpan timeout) +49 System.ServiceModel.Channels.CommunicationObject.Open(TimeSpan timeout) +261 System.ServiceModel.HostingManager.ActivateService(String normalizedVirtualPath) +121 System.ServiceModel.HostingManager.EnsureServiceAvailable(String normalizedVirtualPath) +479

    My C# application throws a System.IO.IOExcepton (The directory name is invalid) for the following code for implementing a filewatcher: public void OnChanged(object source, FileSystemEventArgs e) { DirectoryInfo dList = new DirectoryInfo(e.FullPath); FileInfo[] TxtFiles = dList.GetFiles("*.TXT"); } e.FullPath is "C:/Documents and Settings/Bi/Application Data/TestApp/Reports\\0MA01P62240_000005798_TRI_4947712701738551.TXT". If you notice it seems to append a "\\" to the path when it tracks the file. Any idea what the problem may be? Thanks

  • ScheduledExecutorService throwable lost

    - by Andrey
    Hello, Consider I scheduled a Runnable for periodic execution with ScheduledExecutorService and there occurs some system Error like OutOfMemory. It will be silently swallowed. scheduler.scheduleWithFixedDelay(new Runnable() { @Override public void run() { throw new OutOfMemoryError(); // Swallowed } }, 0, delay, TimeUnit.SECONDS); Is it normal? Why doesn't it propagate to the container? What is the correct way to handle such errors? Thanks!

  • Exception if there is IBOutlet in view controller created by initWithNibName

    - by Kail
    When I create a Navigation-based application, the second view controller is created with initWithNibName, if I add a label onto the second view and connect it with IBOutlet in the second view controller. After I navigate to the second view by clicking table cell, and then back to the root view, the application aborts - send message retainCount to a freed object. I know this is caused by the IBOutlet label, which is retained, set nil in viewDidUnload and dealloc in dealloc. But I don't know why, and if I wanna still use IBOutlet, what can I do? Not dealloc it in viewcontroller's dealloc? Anybody could help? Thank you.

  • validate constructor arguments or method parameters with annotations, and let them throw an exceptio

    - by marius
    I am validating constructor and method arguments, as I want to the software, especially the model part of it, to fail fast. As a result, constructor code often looks like this public MyModelClass(String arg1, String arg2, OtherModelClass otherModelInstance) { if(arg1 == null) { throw new IllegalArgumentsException("arg1 must not be null"); } // further validation of constraints... // actual constructor code... } Is there a way to do that with an annotation driven approach? Something like: public MyModelClass(@NotNull(raise=IllegalArgumentException.class, message="arg1 must not be null") String arg1, @NotNull(raise=IllegalArgumentException.class) String arg2, OtherModelClass otherModelInstance) { // actual constructor code... } In my eyes this would make the actual code a lot more readable. In understand that there are annotations in order to support IDE validation (like the existing @NotNull annotation). Thank you very much for your help.

  • How to detect exception when executing Javascript in NPAPI plugin?

    - by Jordfräs
    In a plug-in I am using NPN_Evaluate() to execute some Javascript. How can I detect wether the Javascript raises an exception? Basically I want to execute any piece of Javascript and get the result from it or detect if it raised an exception. I tried wrapping my Javascript code like this: try { // Injected Javascript code here } catch (exc) { exc; } That way the result from NPN_Evaluate() will be an NPObject* containing a property "message" with the exception message if something goes wrong. But how can I know that it is an exception? It might as well be a result from the injected Javascript code. Am I approaching this the wrong way? Can I detect an exception without catching it in Javascript and returning the exception as the result?

  • mysql and .net: when using tableadapters I’m getting MySqlException “insert command denied for user”

    - by Deveti Putnik
    Hi! I am using mysql as db for my asp.net application. Here are the facts: I am using connection string from web.config which has both username and password. I can do SELECT with tableadapter. When I am trying to do INSERT with tableadapter, I am getting "mysqlexception insert command denied for user" error When I try to do INSERT programatically, i.e. using connection, command object, etc. everything is fine. In this case, I'm reading connection string from web.config, too. This can be only applied to GoDaddy hosting, but on local machine I don't have this kind of problems. Can anyone suggest what can I do to make it work on GoDaddy hosting? Regards, D

  • How do you fix "Too many open files" problem in Hudson?

    - by Randyaa
    We use Hudson as a continuous integration system to execute automated builds (nightly and based on CVS polling) of a lot of our projects. Some projects poll CVS every 15 minutes, some others poll every 5 minutes and some poll every hour. Every few weeks we'll get a build that fails with the following output: FATAL: java.io.IOException: Too many open files java.io.IOException: java.io.IOException: Too many open files at java.lang.UNIXProcess.<init>(UNIXProcess.java:148) The next build always worked (with 0 changes) so we always chalked it up to 2 build jobs being run at the same time and happening to have too many files open during the process. This weekend we had a build fail Friday night (automatic nightly build) with the message and every other nightly build also failed. Somehow this triggered Hudson to continuously build every project which failed until the issue was resolved. This resulted in a build every 30 minutes or so of every project until sometime Saturday night when the issue magically disappeared.

  • UnsupportedOperationException on Collection

    - by Duke Vador
    While studying the Collection API, we find that some methods (add, remove,...) may throw a java.lang.UnsupportedOperationException if the current implementation of the Collection does not support those functionalities. Is there,actually, in the JDK, a concrete Collection that does not support those methods ? Thanks a lot for your answers.
