MFC程序生成dmp文件

#include <dbghelp.h>


int GenerateMiniDump(PEXCEPTION_POINTERS pExceptionPointers)
{
	// 定義函數指針
	typedef BOOL(WINAPI * MiniDumpWriteDumpT)(
		HANDLE,
		DWORD,
		HANDLE,
		MINIDUMP_TYPE,
		PMINIDUMP_EXCEPTION_INFORMATION,
		PMINIDUMP_USER_STREAM_INFORMATION,
		PMINIDUMP_CALLBACK_INFORMATION
		);
	// 從 "DbgHelp.dll" 庫中獲取 "MiniDumpWriteDump" 函數
	MiniDumpWriteDumpT pfnMiniDumpWriteDump = NULL;
	HMODULE hDbgHelp = LoadLibrary("DbgHelp.dll");
	if (NULL == hDbgHelp)
	{
		return EXCEPTION_CONTINUE_EXECUTION;
	}
	pfnMiniDumpWriteDump = (MiniDumpWriteDumpT)GetProcAddress(hDbgHelp, "MiniDumpWriteDump");

	if (NULL == pfnMiniDumpWriteDump)
	{
		FreeLibrary(hDbgHelp);
		return EXCEPTION_CONTINUE_EXECUTION;
	}
	// 創建 dmp 文件件
	TCHAR szFileName[MAX_PATH] = {0};
	strcpy_s(szFileName, "Dump.dmp");
	HANDLE hDumpFile = CreateFile(szFileName, GENERIC_READ | GENERIC_WRITE, 
		FILE_SHARE_WRITE | FILE_SHARE_READ, 0, CREATE_ALWAYS, 0, 0);
	if (INVALID_HANDLE_VALUE == hDumpFile)
	{
		FreeLibrary(hDbgHelp);
		return EXCEPTION_CONTINUE_EXECUTION;
	}
	// 寫入 dmp 文件
	MINIDUMP_EXCEPTION_INFORMATION expParam;
	expParam.ThreadId = GetCurrentThreadId();
	expParam.ExceptionPointers = pExceptionPointers;
	expParam.ClientPointers = FALSE;
	pfnMiniDumpWriteDump(GetCurrentProcess(), GetCurrentProcessId(), 
		hDumpFile, MiniDumpWithDataSegs, (pExceptionPointers ? &expParam : NULL), NULL, NULL);
	// 釋放文件
	CloseHandle(hDumpFile);
	FreeLibrary(hDbgHelp);
	return EXCEPTION_EXECUTE_HANDLER;
}

//調用


LONG WINAPI ExceptionFilter(LPEXCEPTION_POINTERS lpExceptionInfo)
{
	// 這裏做一些異常的過濾或提示
	if (IsDebuggerPresent())
	{
		return EXCEPTION_CONTINUE_SEARCH;
	}
	return GenerateMiniDump(lpExceptionInfo);
}

在   OnInitDialog中調用  SetUnhandledExceptionFilter(ExceptionFilter);   設置異常處理函數即可。

 

提供一份生成dmp文件的測試代碼

	char *p1 = NULL;
	char p2[20] = {0};
	strcpy_s(p2,10,p1);
