The problem is happening with those methods that return and array, as
the others work fine.
I am using defaultNamedNotOptArg= pythoncom.Missing
Is there something else I should check?
Try using pythoncom.Empty instead of Missing. Missing can be interpreted
as the end of
the argument list, so the app sees no arguments at all.
It would be very interesting if that was the problem. Empty makes most
sense for "out" args, but it is impossible/pointless to have Empty
specified after Missing - and many common objects work much better with
Missing. I wish I knew exactly what VB did (and I suppose some
reverse-engineering could probably tell us), but that will need a
round-tuit too...
