tricky(?) win32com question - Mark Hammond or other experts please.

[cfriedalek at gmail.com]

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.
