How to create minidump for my process when it crashes?
提问by Satbir
I am not able to create minidump form my process by changing system setting. So my Question is :
我无法通过更改系统设置从我的进程中创建小型转储。所以我的问题是：
Will the system create a minidump for a user process when it crashes
If yes, which setting do I need to configure
Or do I have to create minidump programmatically.
How effective are minidumps while investigating a crash
系统崩溃时是否会为用户进程创建一个小型转储
如果是，我需要配置哪些设置
或者我必须以编程方式创建小型转储。
小型转储在调查崩溃时的效果如何
I'm using Windows XP, C++, VC6

You need to programatically create a minidump (with one exception, see next link). CodeProject has a nice article on MiniDumps. Basically, you want to use dbghelp.dll, and use the function MiniDumpWriteDump()(see MSDN on MiniDumpWriteDump).
您需要以编程方式创建一个小型转储（有一个例外，请参阅下一个链接）。CodeProject 有一篇关于 MiniDumps的好文章。基本上，您想使用dbghelp.dll, 并使用该功能MiniDumpWriteDump()（请参阅MiniDumpWriteDump 上的 MSDN）。
How effective such dumps are depends very much on the application. Sometimes, for optimized binaries, they are practically useless. Also, without experience, heap/stack corruption bugs will lead you astray.
此类转储的有效性在很大程度上取决于应用程序。有时，对于优化的二进制文件，它们实际上是无用的。此外，如果没有经验，堆/堆栈损坏错误会导致您误入歧途。
However, if the optimizer was not too hard on you, there is a large class of errors where the dumps dohelp, namely all the bugs where having a stack-trace + values of the locally used variables is useful, i.e. many pure-virtual-function call things (i.e. wrong destruction order), access violations (uninitialized accessed or missing NULL checks), etc.
但是，如果优化器对您不太苛刻，那么转储确实有帮助的一大类错误，即具有堆栈跟踪 + 本地使用变量的值的所有错误，即许多纯虚拟- 函数调用事物（即错误的销毁顺序）、访问冲突（未初始化的访问或缺少 NULL 检查）等。
BTW, if your maintenance policy somehow allows it, port your application from VC6 to something acceptable, like VC8 or 9. You'll do yourself a big favor.
顺便说一句，如果您的维护政策以某种方式允许，请将您的应用程序从 VC6 移植到可接受的版本，例如 VC8 或 9。您会帮自己一个大忙。

I found an excellent article on debugInfo.comThis is worth to read :

We use Google Breakpadin Firefox, although that requires at least Visual C++ 2003. The nice side benefit is that it also supports OS X and Linux.
我们在 Firefox 中使用Google Breakpad，尽管这至少需要 Visual C++ 2003。好的附带好处是它还支持 OS X 和 Linux。

I ended up using CrashRpt on Windows (required me to move the whole codebase and toolchain from MinGW to native Microsoft C/C++ compiler), and google-breakpad on Linux.
我最终在 Windows 上使用了 CrashRpt（要求我将整个代码库和工具链从 MinGW 移动到本机 Microsoft C/C++ 编译器），并在 Linux 上使用 google-breakpad。
