IronPython COM Interop: How do I chain through my interop assembly to access types from other COM components?

Question

Hi.

I'm doing .NET interop via a wrapper assembly generated by tlbimp. Anyway, this thirs party COM object has a method that returns a referance to another 3rd party typelib - actually, DAO350. Calling the method that returns this causes IronPython to fail, presumably because it can't find a type to match it to.

Any ideas as to how I can get this object? DO i need to generate another interop assembly for it, and then cast the COM return value?

This is a partial traceback I get:

Traceback (most recent call last):
  File "<console>", line 1, in <module>
EnvironmentError: System.Runtime.InteropServices.COMException (0x800A0CB3): Oper
ation is not supported for this type of object.
