Have you tried:
>> headerObj.name = "value"
and
>> headerObj.SetAttribute('name', 'value')
or
>> headerObj.Attribute['name'] = 'value'
Just an idea :)

Subject: how to call 'overloaded' COM methods
Hi,
I am trying to invoke some calls on com objects, and I am getting
weird errors. The calls seem a little strange to me (overloaded
functions or something like that) and I was wondering if anyone can
help.
The interface is defined here
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wmrm/ht
m/headerattribute.asp
If I use the python command line, here is what I get
>>> headerObj = win32com.client.Dispatch("Wmrmobjs.WMRMHeader")
>>> headerObj.Attribute("name") = "value"
Traceback (SyntaxError: can't assign to function call
As I need this to be run as an asp, I seem to be getting different
errors there. I get a 500 as the response and on the win32traceutil I
see a TypeError as shown below.
Thanks.
Anesh.
