Faulting application name: Application.exe, version: 4.2.11.0, ti开发者_StackOverflow社区me stamp: 0x4e8d8e86 Faulting module name:myDll.DLL_unloaded, Exception code: 0xc0000005 Fault offset: 0x0000000180004d3c Faulting module path: myDll.DLL Report Id: 5608bfd7-f014-11e0-9df7-001cc05d00b7

thanks!

It means that MyDll.DLL was unloaded while it still had active code (either running at the time, or waiting to run because it is on the stack or is registered as a callback), so when the program went to execute the code, there was no code there any more. You need to investigate why your DLL is being unloaded and prevent it from being unloaded while it is still has active code.
