access-violation

问题 This is my code that throws an exception, it just randomly started today here is the photo : Here is the whole page code and the error exception : public frmWFDocumentDetail() { InitializeComponent(); NavigationInTransition navigateInTransition = new NavigationInTransition(); navigateInTransition.Backward = new TurnstileTransition { Mode = TurnstileTransitionMode.BackwardIn }; navigateInTransition.Forward = new TurnstileTransition { Mode = TurnstileTransitionMode.ForwardIn };

问题 So I have a native 3rd party C++ code base I am working with (.lib and .hpp files) that I used to build a wrapper in C++/CLI for eventual use in C#. I've run into a particular problem when switching from Debug to Release mode, in that I get an Access Violation Exception when a callback's code returns. The code from the original hpp files for callback function format: typedef int (*CallbackFunction) (void *inst, const void *data); Code from the C++/CLI Wrapper for callback function format: (I

问题 I have a large Compact Frameworks V2.0 application that in most cases works very well. On certain devices about once a day, a user receives a Native Error 0xC0000005 that is not caught with the standard managed Try/Catch block. My application synchronizes with the server via ASMX calls at fixed intervals. The problem appears to occur during synchronization. There is considerable business logic in addition to the ASMX call that happens at the time of the synchronization, but 98% of that is

问题 If I'm creating a new project in unmanaged C++, Visual Studio 2008 or greater, which exception handling model do I want to go with? I understand that /EHa option results in less efficient code, and also catches SEH exceptions, right? So I have been steering clear of that option and typically going with /EHsc, so that I'm only catching C++ exceptions that are actually thrown and not catching access violations and other structured execptions, in catch(...) handlers. If there is an access

问题 Our application experiences the odd fatal System.AccessViolationException. We see these as we've configured the AppDomain.CurrentDomain.UnhandledException event to log the exception. Exception: System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. at System.Windows.Forms.UnsafeNativeMethods.DispatchMessageW(MSG& msg) at System.Windows.Forms.Application.ComponentManager.System.Windows.Forms.UnsafeNativeMethods

问题 Here is the prototype for a C function that resides in a DLL: extern "C" void__stdcall__declspec(dllexport) ReturnPulse(double*,double*,double*,double*,double*); In another thread, I asked about how to properly create and send the necessary arguments to this function. Here is the thread: How do I wrap this C function, with multiple arguments, with ctypes? So I have used the good information in the thread above, but now I am getting this error: WindowsError: exception: access violation writing

问题 I've started seeing an AccessViolationException being thrown in my application a several different spots. It never occured on my development pc, our test server. It also only manifested itself on 1 of our 2 production servers. Because it only seemed to happen on one of our production servers, I started looking at the installed .net framework versions on the servers. I found that (for some strange reason), the production server that was having problems had 2.0 sp2, 3.0 sp2, and 3.5 sp1, while
