SetUnhandledExceptionFilter

SetUnhandledExceptionFilter 设置未捕获异常处理

通常windows程序长时间运行，会发生各种问题，例如访问异常，内存溢出，堆栈破坏等。

这时候通常希望程序自己能增加处理，而不是依靠系统弹出错误提示框(灰常不友好).

//For proc exception
LONG WINAPI ExpFilter(struct _EXCEPTION_POINTERS *pExp)
{
    ACE_DEBUG((LM_ERROR, "Exception code : %X, address: %x Exit!\n",
        pExp->ExceptionRecord->ExceptionCode,
        pExp->ExceptionRecord->ExceptionAddress));

    MessageBox(NULL, "Exception", "提示", MB_OK);
    //::exit(-);

    return EXCEPTION_EXECUTE_HANDLER;
} 

//Test exception
// Exception code c0000374
//RaiseException(0xc0000374, 0, 0, NULL);     

// Exception code c0000005
// int* p1 = NULL;
// *p1 = 99;  

//For exception in main
::SetUnhandledExceptionFilter(ExpFilter);

PS: The RaiseException function raises an exception in the calling thread.

MSDN中有关SetErrorMode的详细描述,可以这样调用。

//The system does not display a message box when it fails to find a file. Instead, the error is returned to the calling process.

SetErrorMode(SEM_NOOPENFILEERRORBOX)
