MiniDumpReader & crashrpt http://code.google.com/p/crashrpt/

StackTracer http://www.codeproject.com/KB/exception/StackTracer.aspx

any way to get function and line of code when project crashed in release mode
without require pdb file or map file or source file ?

Answer 1

PDB files are meant to provide you this information; the flaw is that don’t you want a PDB file. I can understand not wanting to release the PDB to end users, but in that case why would you want them to see stack trace information? To me your goal is conflicting with itself.

The best solution for gathering debug info from end users is via a minidump, not by piecing together a stack trace on the client.

So, you have a few options:

1. Work with minidumps (ideal, and quite common)
2. Release the PDBs (which won’t contain much more info than you’re already trying to deduce)
3. Use inline trace information in your app such as __LINE__, __FILE__, and __FUNCTION__.
4. Just capture the crash address if you can’t piece together a meaningful stack trace.

Hope this helps!
