在客户机器上如何得到应该程序的详细出错信息， 这里使用drwtsn32，在应用程序崩溃的时候自动将调用栈的信息以文件形式保存在磁盘。
生成dump有drwtsn32, NTSD,CDB等多种工具，drwtsn32 于系统自带。
在项目中使用以下几个步骤：
1. 创建minidmp.h
#pragma once #include #include #include #pragma comment(lib, "dbghelp.lib") inline BOOL IsDataSectionNeeded(const WCHAR* pModuleName) { if(pModuleName == 0) { return FALSE; } WCHAR szFileName[_MAX_FNAME] = L""; _wsplitpath(pModuleName, NULL, NULL, szFileName, NULL); if(wcsicmp(szFileName, L"ntdll") == 0) return TRUE; return FALSE; } inline BOOL CALLBACK MiniDumpCallback(PVOID pParam, const PMINIDUMP_CALLBACK_INPUT pInput, PMINIDUMP_CALLBACK_OUTPUT pOutput) { if(pInput == 0 || pOutput == 0) return FALSE; switch(pInput->CallbackType) { case ModuleCallback: if(pOutput->ModuleWriteFlags & ModuleWriteDataSeg) if(!IsDataSectionNeeded(pInput->Module.FullPath)) pOutput->ModuleWriteFlags &= (~ModuleWriteDataSeg); case IncludeModuleCallback: case IncludeThreadCallback: case ThreadCallback: case ThreadExCallback: return TRUE; default:; } return FALSE; } inline void CreateMiniDump(EXCEPTION_POINTERS* pep, LPCTSTR strFileName) { HANDLE hFile = CreateFile(strFileName, GENERIC_READ | GENERIC_WRITE, 0, NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL); if((hFile != NULL) && (hFile != INVALID_HANDLE_VALUE)) { MINIDUMP_EXCEPTION_INFORMATION mdei; mdei.ThreadId = GetCurrentThreadId(); mdei.ExceptionPointers = pep; mdei.ClientPointers = FALSE; MINIDUMP_CALLBACK_INFORMATION mci; mci.CallbackRoutine = (MINIDUMP_CALLBACK_ROUTINE)MiniDumpCallback; mci.CallbackParam = 0; MINIDUMP_TYPE mdt = (MINIDUMP_TYPE)(MiniDumpWithPrivateReadWriteMemory | MiniDumpWithDataSegs | MiniDumpWithHandleData | 0x00000800 /*MiniDumpWithFullMemoryInfo*/ | 0x00001000 /*MiniDumpWithThreadInfo*/ | MiniDumpWithUnloadedModules); MiniDumpWriteDump(GetCurrentProcess(), GetCurrentProcessId(), hFile, mdt, (pep != 0) ? &mdei : 0, 0, &mci); CloseHandle(hFile); } }
2、 实现UnhandledExceptionFilter
#include "minidmp.h" LONG WINAPI GPTUnhandledExceptionFilter(PEXCEPTION_POINTERS pExceptionInfo) { //得到当前时间 SYSTEMTIME st; ::GetLocalTime(&st); //得到程序所在文件夹 TCHAR exeFullPath[256]; // MAX_PATH GetModuleFileName(NULL,exeFullPath,256);//得到程序模块名称，全路径 CString strPath; DWORD nLoc; strPath.Format("%s",exeFullPath); nLoc = strPath.ReverseFind('//'); strPath.Delete(nLoc+1,strPath.GetLength()-nLoc); LPSTR szFileName; wsprintf(szFileName, TEXT("%sERLOG_%04d%02d%02d%02d%02d%02d%02d%02d.dmp"),strPath, st.wYear, st.wMonth, st.wDay, st.wHour, st.wMinute, st.wSecond, st.wMilliseconds, rand()%100); CreateMiniDump(pExceptionInfo, szFileName); std::cerr << "未知错误：" << (*pExceptionInfo->ExceptionRecord) << std::endl; exit(pExceptionInfo->ExceptionRecord->ExceptionCode); return EXCEPTION_EXECUTE_HANDLER; // 程序停止运行 }
3. 在异常发生之前调用SetUnhandledExceptionFilter(GPTUnhandledExceptionFilter); 通常在Main()函数开始时调用即可。
注：必需有dbghlp.dll
