variant com issues/problems in python

Hi, all.

Just a quick question, when setting a COM process to read a value from
a pre-defined register index, I think, I have to change the variable
that the value will be returned to (as I have to do for the same
function in perl), into a VARIANT, However when i run the variant
code....

'serialIndex = win32com.client .pythoncom.VT_V ARIANT'

no matter what extension I use (i.e. VT_I4 or VT_BOOL etc etc) it
still returns a type mismatch error. I may be doing something wrong or
getting confused with variant processes in python. I do know the code
I use in perl to do this works but I dont know how to translate this,
fully, into python.

perl code for variant =
Win32::OLE::Var iant::Variant(W in32::OLE::Vari ant::VT_VARIANT |Win32::OLE::VA RIANT::VT_BYREF ,
0)

Cheers in advance,
Matt
