}在InitInstance()中调用
BOOL AtCodeMaster::InitInstance()
{// 如果一个运行在 Windows XP 上的应用程序清单指定要// 使用 ComCtl32.dll 版本 6 或更高版本来启用可视化方式， // 则需要 InitCommonControlsEx()。 否则，将无法创建窗口。 INITCOMMONCONTROLSEX InitCtrls;InitCtrls.dwSize = sizeof(InitCtrls);// 将它设置为包括所有要在应用程序中使用的// 公共控件类。InitCtrls.dwICC = ICC_WIN95_CLASSES;InitCommonControlsEx(&InitCtrls);excep.RunCrashHandler();//使用.dmp定位bug（优雅崩溃）

MFC程序崩溃时生成dmp文件失败
我MFC项目的dmp日志总是生成在C:\Users\Administrator\AppData\Local\CrashDumps目录，我想保存在其它的位置。 SetUnhandledExceptionFilter(UnhandledExceptionFilterEx); 始终未被执行
第一种方法：修改注册表
第二种方法：在C++应用程序中动态修改注册表（需要管理员权限）
void HiExceptionHandle::SetWERDumpLocation(const std::wstring dumpFolderPath)
{HKEY hKey = NULL;LONG result = RegCreateKeyEx(HKEY_LOCAL_MACHINE,L"SOFTWARE\\Microsoft\\Windows\\Windows Error Reporting\\LocalDumps",0,NULL,REG_OPTION_NON_VOLATILE,KEY_SET_VALUE,NULL,&hKey,NULL);if (result == ERROR_SUCCESS) {result = RegSetValueEx(hKey,L"DumpFolder",0,REG_SZ,(const BYTE*)dumpFolderPath.c_str(),(dumpFolderPath.size() + 1) * sizeof(wchar_t));if (result != ERROR_SUCCESS) {std::wcerr << L"Failed to set DumpFolder value in registry. Error code: " << result << std::endl;}RegCloseKey(hKey);}else {std::wcerr << L"Failed to create LocalDumps key in registry. Error code: " << result << std::endl;}// Optionally, you can also set the DumpType value here
}
调用：
void HiExceptionHandle::RunCrashHandler()
{ SetWERDumpLocation( L"D:\\Log\\dump");SetUnhandledExceptionFilter(UnhandledExceptionFilterEx);
}
运行效果：
