About wmi

I want to prevent some process from running. The code is in the
following. I encounter some unexpected troubles.
Probelm1: This program cannot terminate "scrcons.ex e" and
"FNPLicensingSe rvice.exe",whic h are system processes.
Problem2:After a while, this program will abort by error
File "C:\Python25\li b\wmi.py", line 397, in __call__

[... snip code ...]

You should probably post this to comp.python.win dows. Tim Golden
(author of WMI interface) monitors that list religously (thanks Tim).

Actually, I follow this one pretty much, too. I've just been a bit busy
these last few days. And still am, so this answer will be short :)


1) I'm not sure if WMI can be forced to close down system processes,
but if it can it's probably by means of specifying one or more
privileges when you connect. Try looking in the WMI newsgroups
for a more general (non-Python) answer to this and I'll happily
explain how to apply it in a Python context.

2) I can't quite see from this traceback where the problem
arises. Have you snipped the traceback at all, or was that
all there was? Can you narrow the thing down to a short
snippet of code which I'm likely to be able to run independently,
please?

Sorry for the haste.

Hi,

1) I'm not sure if WMI can be forced to close down system processes,
but if it can it's probably by means of specifying one or more
privileges when you connect. Try looking in the WMI newsgroups
for a more general (non-Python) answer to this and I'll happily

I use VBS to kill these processes,the VBS cannot kill these either.

import wmi

c = wmi.WMI ()
process_watcher = c.Win32_Process .watch_for("cre ation")
while True:
new_process = process_watcher ()
if new_process.Cap tion == 'notepad.exe':
print "start killing.."
sleep(5)
result = new_process.ter minate()
print "killed"
We must start the notepad.exe manually, then (1) kill the notepad.exe
by this code.
(2)we kill the notepad.exe before this code manually. Both will result
in errors.

Well that looks embarrassingly like a complete lack
of unicode-awareness in the wmi module. Would you
mind trying this version:

http://timgolden.me.uk/wmi-project/wmi.py

which is a copy of the svn trunk to see if that
improves the UnicodeDecode error, please? I'll
try to get an install of a non-English edition of
Windows but, as you might imagine, I normally run
the UK version so don't hit these kind of issue
myself.

I'm not sure exactly what's causing that
particular effect, but I would suggest that
you call the method as .Terminate (note the
initial capital). On my box, calling .terminate
simply raises an AttributeError as expected,
but I do remember encountering the situation
you're describing in some situation which
now escapes me.

At any rate, try using:

result, = new_process.Ter minate ()

and note that the return value is a tuple,
not a single number. The code will work either
way, but in your case "result" will be a tuple
of length one; in mine, result will be a number.

I expect you can test successfully at a non-English edition

Windows is sometime case insensitive,but the python is case sensitive.
I also encountered this kind of problems.

Thanks for Tim's help.

Oh well. It was only a quick fix! I'll try
to get some kind of non-ASCII edition of Windows
to test against. As I understand it, the situation
is that some WMI exception (ie coming from the
underlying WMI/COM subsystem) results in an error
message which contains non-ASCII characters.

Just so I'm not chasing red herrings, could you
paste the output from the following code, please?

<code>
import wmi # use the version linked above

c = wmi.WMI ("non-existent computer")

#
# Should give a traceback here for the DCOM
# error, not a UnicodeDecodeEr ror.
