I'm trying to kill processes,

Why are the subprocess.Popen methods kill() and terminate () not working,

perfect ?
...
My_Process = subprocess.popen ( ...)
handle = win32api.OpenProcess(win32con.PROCESS_TERMINATE, 0,
My_Process.PID)
try:
win32api.TerminateProcess(handle,0)
win32api.CloseHandle(handle)

There shouldn't be any difference. If you look at the code in
subprocess. it calls the same API. The handle returned from
CreateProcess has all access rights, including PROCESS_TERMINATE.
Can you show us your original code?
Good Question Tim.
Showing the code is always difficult for me, because I encapsulate these
complex things.
The code I gave above doesn't work either :-)
I use a kill method that also kills the children and seems to be the
essential thing is this situation,
(btw why are there children ?)
thanks for the tip,
cheers,
