Check a windows service

[awel]

Hi,

I'm new in python and I would like to know if it's possible to check if
a specific windows service is present and if it's possible how can I
do?

Thanks

This is one way:

You'd have to change that example slightly, but I
hope the principal is clear enough. If not, ask again.

Here's some code cut & pasted from the demos included in the win32 module:

import win32service
import win32con


def EnumServices():
resume = 0
accessSCM = win32con.GENERI C_READ
accessSrv = win32service.SC _MANAGER_ALL_AC CESS

#Open Service Control Manager
hscm = win32service.Op enSCManager(Non e, None, accessSCM)

#Enumerate Service Control Manager DB

typeFilter = win32service.SE RVICE_WIN32
stateFilter = win32service.SE RVICE_STATE_ALL

statuses = win32service.En umServicesStatu s(hscm, typeFilter, stateFilter)
for (short_name, desc, status) in statuses:
print short_name, desc, status

Yes, using the wmi module, but you'll have to search the Microsoft
documentation on how to enumerate services and their properties:
http://msdn2.microsoft.com/en-us/library/aa384642.aspx
The code might look like this, but the names may be wrong:

import wmi
import pythoncom
pythoncom.CoIni tialize()
w = wmi.WMI()
for s in w.Win32_Service s():
print s

Re: Check a windows service

Sorry, but could you give me an example with a real service 'cause I've
tried this script but nothings happened, no error, nothings ; even if I
launch it in cmd prompt.

Thanks

You have to call the EnumServices function if you want some useful output.
Copy&paste the code in a new file, add these 2 lines at the end, and
save the file with a .py extension:

if __name__=='__ma in__':
EnumServices()

Then execute it with: python your_file_name. py
See

http://diveintopython.org/getting_to_know_python/testing_modules.html

to understand what's that; and read the whole book, it's a good
tutorial if you already know another language.

Well, as that example said, it was designed to show
automatic services which are not running. If you don't
have any then nothing will show. I assumed you could
use this as a starting point.

To list all services try this:

<code>
import wmi

c = wmi.WMI ()
for service in c.Win32_Service ():
print service.Caption

</code>

To show a specific service:

<code>
import wmi

c = wmi.WMI ()
for service in c.Win32_Service (Caption="Task Scheduler"):
print service

</code>

Re: Check a windows service

Thanks for all 'cause you've really helped me

Just one thing in the last line for the specific service, you' ve
writted :

print service

but I think it is :

print service.Caption
