<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>I am experiencing a weird problem when
using third-party software through COM. There is an API function X belongs to
Object A from that third-party software. I use python generated COM interface
and use dispatch to get that Object A. Then I call that function X in python.
The function X requires an unsigned integer N as a parameter along with 2 other
parameters. But for some reason, the parameter N got changed after it’s
going through COM, it’s changed to 0xFFFFFFFF. I printed the parameter
before calling that function X in python and the function in third-party print
out the initial parameter it receives. These two print-outs are different. I
also experienced with other Object in that third-party software. The problem
doesn’t exist in other object or other functions in object A.<o:p></o:p></span></font></p>

wrong here? I don’t know if the problem lies in my part of python program
or in the python win32com or in the third-party COM support.<o:p></o:p></span></font></p>
