The type lib is clearly broken.  I would expect this control would also have problem with COM marshalling.

The best solution is clearly to fix the type lib.  This may not be possible tho :)

You are pretty much SOL with makepy as it stands - garbage in, garbage out :)

You will have to pass custom type-tuples to InvokeTypes().  This may be as simple as changing the sample makepy generated code you pased, changing the second integer in the OUT param tuples from 1 to 2 (win32com.PARAMFLAG_FOUT)
