一个宏命令，就可以程序崩溃时生成dump文件

在主程序初始化时加入

DeclareDumpFile();

 

创建头文件DumpFile.h, 将下列代码放进文件中  2   3 #pragma once  4 #include <windows.h>  5 #include < Dbghelp.h>  6 #include <iostream>    7 #include <vector>    8 using namespace std;   9  10  11 #pragma comment(lib, "Dbghelp.lib") 12  13  14 namespace NSDumpFile 15 {  16     void CreateDumpFile(LPCWSTR lpstrDumpFilePathName, EXCEPTION_POINTERS *pException)   17     {   18         // 创建Dump文件   19         //   20         HANDLE hDumpFile = CreateFile(lpstrDumpFilePathName, GENERIC_WRITE, 0, NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);   21  22  23         // Dump信息   24         //   25         MINIDUMP_EXCEPTION_INFORMATION dumpInfo;   26         dumpInfo.ExceptionPointers = pException;   27         dumpInfo.ThreadId = GetCurrentThreadId();   28         dumpInfo.ClientPointers = TRUE;   29  30  31         // 写入Dump文件内容   32         //   33         MiniDumpWriteDump(GetCurrentProcess(), GetCurrentProcessId(), hDumpFile, MiniDumpNormal, &dumpInfo, NULL, NULL);   34  35  36         CloseHandle(hDumpFile);   37     }   38  39  40     LPTOP_LEVEL_EXCEPTION_FILTER WINAPI MyDummySetUnhandledExceptionFilter(LPTOP_LEVEL_EXCEPTION_FILTER lpTopLevelExceptionFilter) 41     { 42         return NULL; 43     } 44  45  46     BOOL PreventSetUnhandledExceptionFilter() 47     { 48         HMODULE hKernel32 = LoadLibrary(_T("kernel32.dll")); 49         if (hKernel32 ==   NULL) 50             return FALSE; 51  52  53         void *pOrgEntry = GetProcAddress(hKernel32, "SetUnhandledExceptionFilter"); 54         if(pOrgEntry == NULL) 55             return FALSE; 56  57  58         unsigned char newJump[ 100 ]; 59         DWORD dwOrgEntryAddr = (DWORD) pOrgEntry; 60         dwOrgEntryAddr += 5; // add 5 for 5 op-codes for jmp far 61  62  63         void *pNewFunc = &MyDummySetUnhandledExceptionFilter; 64         DWORD dwNewEntryAddr = (DWORD) pNewFunc; 65         DWORD dwRelativeAddr = dwNewEntryAddr -  dwOrgEntryAddr; 66  67  68         newJump[ 0 ] = 0xE9;  // JMP absolute 69         memcpy(&newJump[ 1 ], &dwRelativeAddr, sizeof(pNewFunc)); 70         SIZE_T bytesWritten; 71         BOOL bRet = WriteProcessMemory(GetCurrentProcess(),    pOrgEntry, newJump, sizeof(pNewFunc) + 1, &bytesWritten); 72         return bRet; 73     } 74  75  76     LONG WINAPI UnhandledExceptionFilterEx(struct _EXCEPTION_POINTERS *pException) 77     { 78         TCHAR szMbsFile[MAX_PATH] = { 0 }; 79         ::GetModuleFileName(NULL, szMbsFile, MAX_PATH); 80         TCHAR* pFind = _tcsrchr(szMbsFile, '\\'); 81         if(pFind) 82         { 83             *(pFind+1) = 0; 84             _tcscat(szMbsFile, _T("CrashDumpFile.dmp")); 85             CreateDumpFile(szMbsFile, pException); 86         } 87  88  89         // TODO: MiniDumpWriteDump 90         FatalAppExit(-1,  _T("Fatal Error")); 91         return EXCEPTION_CONTINUE_SEARCH; 92     } 93  94  95     void RunCrashHandler() 96     { 97         SetUnhandledExceptionFilter(UnhandledExceptionFilterEx); 98         PreventSetUnhandledExceptionFilter(); 99     }100 };101 102 103 #define DeclareDumpFile() NSDumpFile::RunCrashHandler();
