Update: The functions that don't work return Record types, and the ones
that do work just return multiple values (a tuple).
Do I need to pass in the appropriate Record type (or an empty record)
during each function call?
If so, how do I get to the Record types that I see in the python object
browser (python -m win32com.client.combrowse)?
Thanks,
Terry
