Question

Is there some way, similar to “bm Module!Symbol” to set a breakpoint on a specific method of a COM class in windbg? It looks like a COM DLL only exports four symbols (DllCanUnloadNow, DllGetClassObject, DllRegisterServer, and DllUnregisterServer), so the usual “bm” approach doesn’t work. I’m assuming there’s some other way to do it, but I haven’t been able to find it in the past hour or so.

You should be able to use bu (unresolved breakpoint). I believe the syntax is as follows, but my memory may be rusty:

bu MyDll!MyClass::MyMethod
