Thanks alot for your help. I had tried using threading with a
different setup in the function side but did not get success. I think
that I have winner now. Thanks again. What follows is the what I have
working so far. And another question why do you prefer to us threading
and thread?
import wmi
import pythoncom
import threading
def create():
pythoncom.CoInitialize()
c = wmi.WMI()
while 1 :
print "watching creation"
watcher = c.watch_for(notification_type="Creation",
wmi_class="Win32_Process", delay_secs=1)
print watcher()
def delete():
pythoncom.CoInitialize()
d = wmi.WMI()
while 1 :
print "watching deletion"
watcher = d.watch_for(notification_type="Deletion",
wmi_class="Win32_Process", delay_secs=1)
print watcher()
import threading
threading.Thread(target=create).start()
threading.Thread(target=delete).start()
Cheers
