[python-win32] Passing Args through PythonService.exe

[Michael Manfre]

I installed the service with the args I wanted and they appeared where I
expected to see them in the service's property dialog (next to the "Path to
executable"). The problem I experienced was that no matter what args were
provided, either installed with the service or provided with the one-off
"start parameters", the sys.argv as seen by my code was a tuple containing
the service's _svc_name_ as set by my win32serviceutil.ServiceFramework
class. I've since given up on using PythonService.exe and am now using
another mechanism.

Regards,
Michael Manfre
