[windows]_[Primary]_[release Program crash report minidump solution]

Scene:

1. When the release program crashes, the crash report allows the developer to pinpoint where the code has gone wrong and is useful.

2. Only the compiler with VS is supported, so the MINGW is not available.

3. The unhandled exception filtering handler is used.

4. The generated. dmp file is compressed with the Zlib library, using the following Ziphelper class, which requires zlib libraries and dbghelp.lib at compile time

5. The use of Dbgreport as a member variable of the app class, or a file-scoped global variable is initialized, before the program runs before the start of the call

Registercrashfilter

6. Helpful help to top down or leave a message.
