Windbg command to get all gdi handle count from a crash dump

Question

I have a crash dump and I suspect GDI leaks to be a cause of the crash

From the full crash dump is there anyway to find out the number of GDI handles used by my process when it crashed?

Answer 1

It is unlikely since the only debugger extension gdikdx.dll tailored at gdi tasks is not actively maintained since the w2k version and i believe they stopped shipping it since not that many folks are into hacking into gdi internals - according to someone's statement i stumbled upon in a newsgroup - therefore it is no longer invested into. You're left with only a few options all of which are unfortunately about runtime troubleshooting.

You could start with a tool like nirsoft's GDIView to monitor the use of GDI resources from your app and then progress to any of the runtime instrumentation options:

• gdi leaks detector tool described on msdn
• bug browser
• leaktrap

P.S. could you be more specific on the actual reason of your particular crash?

Tess talks about a similar situation, perhaps this will give you a lead...
