I so much more prefer python. Try either pythoncom.Missing, pythoncom.Empty, or pythoncom.ArgNotFound.

You could email him directly, or ask your question on the pywin32 mailing list, or raise a bug/feature request on sourceforge -- he not only reads those, he actions them :-) > > --- > > I'm using pywin32com to drive a 3rd party app. The app has a VBS based > API.

tricky(?) win32com question - Mark Hammond or other experts please.
OK, I've asked this earlier this week with no response. Since then I've also received a suggestion from the app developers but that failed with the same type error problem. Hopefully Mark Hammond or other experts can offer a suggestion as to how to get around this problem. I'm foolish enough to think that a solution can be found. Or can someone suggest how to pm Mark. --- I'm using pywin32com to drive a 3rd party app. The app has a VBS based API. In VBS a specific query for data goes like this: Plot.QueryBegin datacode, Nothing where datacode is a number and Nothing is a VBS type/keyword The nominal python equivalent doesn't work. Plot.QueryBegin(datacode, None) gives a type mismatch error as follows: com_error: (-2147352571, 'Type mismatch.', None, 2) >From what I've been able to discover Nothing is not a null, 0, False, "" Table 12.2 of http://www.oreilly.com/catalog/pythonwin32/chapter/ch12.html does not mention Nothing in its list of Variant types. Please, any clues about how to handle this (apart from running the query in VBS). I so much more prefer python. -- http://mail.python.org/mailman/listinfo/python-list
