Access Violation Error Message
example, if something went wrong and the program tried to access something that it wasn't supposed to, how would you get an error message to appear saying "Memory Access Violation!" instead of just terminating the process and not showing the user any information about the crash? I'm programming a game for Windows using MinGW, if that helps any. c++ try-catch access-violation share|improve this question edited May 17 '13 at 17:25 Charles 40.1k1069107 asked May 17 '13 at 15:10 rsethc 588314 try access violation error windows 7 ... catch perhaps? –Roger Rowland May 17 '13 at 15:13 1 Why would someone want to prevent a berserk program which try to modify protected memory from terminating ? –lucasg May 17 '13 at 15:13 Typically you don't "catch" these, you fix them from happening in the first place by running them through a debugger, such as GDB. –hexist May 17 '13 at 15:19 1 I think he just want to show a neat exit window instead of default OS window, then let it terminate anyway. Nothing wrong with that. –Cyrille May 17 '13 at 15:21 Yes, Cyrille that is exactly what I want to do. So that in case of a bug the user doesn't just get a crash to desktop and go "What just happened?". –rsethc May 17 '13 at 15:23 | show 4 more comments 1 Answer 1 active oldest votes up vote 7 down vote Access violation is a hardware exception and cannot be caught by a standard try...catch. Since the handling of hardware-exception are system specific, any solution to catch it inside the code would also be system specific. On Unix/Linux you could use a SignalHandler to do catch the SIGSEGV signal. On Windows you could catch these structured exception using the __try/__except statement. share|improve this answer edited May 17 '13 at 15:27 Akanksh 1,13069 answered May 17 '13 at 15:15 zakinster 7,7442140 Is it possible to have a 'main' process that l

I cannot dig in so I'm only wondering if there is anyway to catch it so not collapse the application. I tried the following 4 methods but none of them works. 1, try { sts = resFilter->initialize(m_JPEG2000File); // it throws that exception } catch (...){ printf("Gotcha0..."); int a = 34; } 2, 3 and 4 LONG WINAPI CrashHandler1(EXCEPTION_POINTERS * a/*ExceptionInfo*/) { std::cout << "Gotcha1!" << std::endl; http://stackoverflow.com/questions/30806174/catch-the-access-violation-reading-location-0x00000000-exception return 0; } void CrashHandler2() { std::cout << "Gotcha2!" << std::endl;} void CrashHandler3() { std::cout << "Gotcha3!" << std::endl;} // in Main() ::SetUnhandledExceptionFilter(CrashHandler1); std::set_terminate (CrashHandler2); std::set_unexpected( CrashHandler3 ); Test(); // It would throw "Access violation reading location 0x00000000" exception If I debug it, exception would be thrown. If I run it in run time, "Gotcha1!" would be displayed in the console but the application would still collapse. Is there any way I can eat this exception? Thanks in advance, Ben Edit: @Adriano Repetti mentioned __try and __except can catch this exception. Thanks for all you guys heads-up for not eating that exception! I have an external C# executable calling this project. I want to catch this exception so I have chance to log the error and do not collapse the C# application. I would still terminate this very c++ process. I'm looping the data in C# which would start a new C++ process from scratch every time, so it would be a new C++ instance. So Adriano's approach works for me. c++ exception try-catch share|improve this question edited Jun 12 '15 at 20:36 asked Jun 12 '15 at 14:57 Ben 1315 3 try with __try and __except (access violation isn't something known by C++) but I'd suggest to do not do it.

This is a 64-bit Windows application compiled using Visual Studio 2013, written in C++. For testing I am using the default C++ Win32 project generated by VS. I am catching all exceptions by registering a handler using SetUnhandledExceptionFilter. This works fine for /most/ cases, but not all. All throw()-n exceptions are caught, and most hardware exceptions like floating point or access violations as well. The code that doesn't trigger access violation error the handler is: std::vector
