//必不可少的头文件和lib库文件
#include "dbghelp.h"
#pragma comment(lib,"dbghelp.lib")


//异常捕获函数
LONG WINAPI UnhandledExceptionFunction(struct _EXCEPTION_POINTERS* pExceptionInfo)
{
	CTime timeCur = CTime::GetCurrentTime();

        //dump文件路径
	CString strCrashFilesPath = _T();
	
	HANDLE hDumpFile = CreateFile(strCrashFilesPath, GENERIC_WRITE, 0, NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);
	MINIDUMP_EXCEPTION_INFORMATION dumpInfo;
	dumpInfo.ExceptionPointers = pExceptionInfo;
	dumpInfo.ThreadId = GetCurrentThreadId();
	dumpInfo.ClientPointers = TRUE;

	MiniDumpWriteDump(GetCurrentProcess(), GetCurrentProcessId(), hDumpFile, MiniDumpNormal, &dumpInfo, NULL, NULL);
	CloseHandle(hDumpFile);

	ExitProcess(0);
	return 1;
}


在程序的入口处添加注册函数，比如mfc对话框的APP::InitInstance()中添加注册（如果是纯c++代码，可以在main()中添加注册）：
SetUnhandledExceptionFilter(UnhandledExceptionFunction);
