Hi.
I wrote a simple WMI provider.
I call the function in the provider through wmic.exe and wbemtest.exe
In XP it works good, but in windows 7 I get an error: Code - 0x800706be. "The remote procedure call failed".
In the event log I see "Application Error" - wmiprvse.exe . Faulting module name: mydll.dll, Exception code - 0xc0000005
What Can I do?
Please help me!
Thanks.

Post the smallest possible compilable example that demonstrates the problem.

The most common cause of this being trying to dereference an invalid pointer, of which the typical case is a NULL pointer.
The first thing to do would be to go through your code and check that any API function you call which returns a pointer/handle of some sort is actually returning a VALID pointer/handle.
Don't assume success based on some limited test (it works on XP). For example, some things you could do on XP will result in "permission denied" on later OS's.
If you silently ignore such a status return and then go on to use the invalid pointer/handle, then you're going to be SoL.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
