之前写过在windows开发中,让你的客户端崩溃之前生成dump文件,今天略微改动改动用在qt上吧。

上面的代码有些啰嗦,同时记录了1些硬件的信息到dump文件中(http://blog.csdn.net/wangshubo1989/article/details/51855895);
如果感觉没用,请自行疏忽。

开始使用:
在main.cc文件中:

首先定义1下回调:

#ifdef Q_OS_WIN long __stdcall callback(_EXCEPTION_POINTERS* excp) { CCrashStack crashStack(excp); QString sCrashInfo = crashStack.GetExceptionInfo(); TCHAR my_documents[MAX_PATH]; SHGetFolderPath(NULL, CSIDL_PERSONAL, NULL, SHGFP_TYPE_CURRENT, my_documents); QString file_path = QString::fromWCharArray(my_documents); QDir *folder_path = new QDir; bool exist = folder_path->exists(file_path.append("\\MyApp")); if(!exist) { folder_path->mkdir(file_path); } delete folder_path; folder_path = nullptr; QString sFileName = file_path + "\\crash.log"; QFile file(sFileName); if (file.open(QIODevice::WriteOnly|QIODevice::Truncate)) { file.write(sCrashInfo.toUtf8()); file.close(); } return EXCEPTION_EXECUTE_HANDLER; } #endif

最后再main中添加:

#ifdef Q_OS_WIN SetUnhandledExceptionFilter(callback); #endif

关于SetUnhandledExceptionFilter不懂的地方可以参考:
