How to make my code creating dump file before crash?

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.

I want to configure the code / the windows OS to create dump file on the crash.

the limitation that i have are ... I have limited access to the machine that this crash reproduce on - this is not developing machine .. this is testing Lab machine

So, How to do it ? How can i change the properties in the solution that a new dump file will created on any crash?

Answer 1

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

Answer 2

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.

Answer 3

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.
