OK playing around I knocked up some test code ...
#!/usr/bin/env python
# -*- coding: iso8859_1 -*-
import subprocess
a = subprocess.Popen('tasklist.exe', bufsize=0, shell=False,
stdout=subprocess.PIPE, stderr=None, stdin=None, universal_newlines=True)
op = a.stdout.readlines()
for i in op:
#print i
#print
pass
#raw_input()
This gives me what I need except when it runs windows flashes up a large black
terminal window for a split second (yuk)
This test would be performed while my app is running so thats not so good :)
Any ideas on how to stop it displaying ?
Dave
