Hi,
I have 2 references to COM objects (through interop). How do I compare
the tow to know if they are pointing to the same COM object?
The Object.Equals doesn't work in this case...
Thanks!

IntPtr IUnkn1 = Marshal.GetIUnknownForObject(o1);
IntPtr IUnkn2 = Marshal.GetIUnknownForObject(o2);
if (IUnkn1 == IUnkn2)
// same object
else
....
