Hi Thomas, that wasn`t it. Your example returns me a list of 500 Nones. It`s right, the method expects a list or a tuple. But it does not matter what is in the list. It returns me everything.
Hint: The number 500 was to initialize the BSTR array with a size of 500. Do I need it in Python ?! The problem is the same with win32com, here: https://sourceforge.net/tracker/?func=detail&atid=551954&aid=1920299&group_id=78018 Any other ideas ? best regards Mustafa Görmezer Thomas Heller schrieb: > Mustafa Görmezer schrieb: >> Hello, >> >> I am automating a CAD System which expects a so called >> CATSafeArrayVariant.
