| I installed Tim Golden's wmi module
| (http://tgolden.sc.sabren.com/python/wmi.html), in the hopes it would
| help me list and work with services on my Win32 machine. Now,
| everything seems fine except for one thing : Listing services!
|
| import wmi
|
| c = wmi.WMI ()
| for s in c.Win32_Service ():
| if s.State == 'Stopped':
| print s.Caption, s.State
|
| and I get :
|
| Traceback (most recent call last):
| File "<stdin>", line 1, in ?
| File "G:\Python-2.4\Lib\site-packages\wmi.py", line 404, in __call__
| return self.wmi.query (wql)
| File "G:\Python-2.4\Lib\site-packages\wmi.py", line 583, in query
| raise WMI_EXCEPTIONS.get (hresult, x_wmi (hresult))
| wmi.x_wmi: -2147217398
Nothing obvious, I'm afraid. I cut-and-pasted the code directly
from your email and it worked fine on my Win2K machine. For your
information, what the code is doing behind the scenes is the following:
<code>
import win32com.client
c = win32com.client.GetObject (
"winmgmts:{impersonationLevel=Impersonate,authenticationLevel=Default}/root/cimv2"
)
for service in c.ExecQuery ("SELECT * FROM Win32_Service"):
if service.Properties_ ("State").Value == "Stopped":
print service.Properties_ ("Caption").Value
print service.Properties_ ("State").Value
</code>
You might try cutting-and-pasting that code into an interpreter window
to see what happens. Likewise, the following code snippet does something
similar for vbs. Save it as something.vbs, and then run it from the
command prompt with "cscript something.vbs" (or however you want to
do it). I'd be interested to know if it gives the same error as the
Python version.
<code>
set wmi = GetObject ("winmgmts:{impersonationLevel=impersonate}")
set ServiceSet = wmi.InstancesOf ("Win32_Service")
for each Service in ServiceSet
WScript.Echo Service.Description
Next
</code>

PS I realise that by now you've probably moved on from
this approach, but if you did manage to pin down a problem
we could address, I'd be very glad to address it.
