Problem listing services with wmi

Hi again Tim,

Any reason I should know about that you haven't updated to 2.4? I just 
got into Python, so I got the latest version, but if there's something 
wrong with 2.4 I'd like to know...

Which is what really puzzles me... From the list of 21 services that 
were gotten by win32service and not wmi, I can't see any service that's 
"special" in any way... So without further investigation, I really 
couldn't say.

But if we can get WMI to just "skip over" the offending service, at 
least then we'll be able to know which one causes this...

>n_services = services.Count

It now fails at the line above, with the following error :

Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "G:\Python-2.4\Lib\site-packages\win32com\client\__init__.py", 
line 455, in __getattr__
    return self._ApplyTypes_(*args)
  File "G:\Python-2.4\Lib\site-packages\win32com\client\__init__.py", 
line 446, in _ApplyTypes_
    return self._get_good_object_(
pywintypes.com_error: (-2147352567, 'Exception occurred.', (0, 
'SWbemObjectSet',  'Critical error ', None, 0, -2147217398), None)

I had tried something similar yesterday, with the same results. It would 
seem (from what I can understand) that c.ExecQuery() just makes a list 
of proxy objects, and that when you call Count on the set, it has to 
create them all for real and that's where it fails when reaching the 
"bad" service.

Thanks again, looking forward to trying other ideas.
