Question

I have some code in C# and C++ ( in one project ). This code have some crash and i trying t find it. but this crash is not reproduce any time - and i can\'t find it.

Answer 1

You can register an unhandled exception filter and PInvoke MiniDumpWriteDump. A code sample to do that is located here

Answer 2

I find it easier to use ProcDump. Try the -e (create dump on unhandled exceptions), -ma (w/ full process memory), and -t (create dump on app termination) options.

Answer 3

You can enable saving dumps on vista in the registry:

1. Open RegEdit
2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting
3. Under Windows Error Reporting, create a new registry key named LocalDumps.
