Kill it ;-) this code is part of an winlogon notification package that setup users' environment like hide drives which require explorer to be restarted. If you're interested in how to make that, here's the subversion's url - for the .dll that runs the python script http://eole.orion.education.fr/depot/listing.php?repname=Eole&path=%2FEole2%2Fscribe%2Fcontrole-vnc%2Ftrunk%2Fsources%2Fcliscribe_dll%2F&rev=0&sc=0 - for the python script itself (look for logon.py) http://eole.orion.education.fr/depot/listing.php?repname=Eole&path=%2FEole2%2Fscribe%2Fcontrole-vnc%2Ftrunk%2Fsources%2Fservscribe%2F&rev=0&sc=0 I've re-written my "isrunning" and the killProcName functions with ctypes which runs very faster than the python version (look for process.py in subversion). _______________________________________________ Python-win32 mailing list Python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32
