problem with a python service

[chriss]

Hello everybody!

I'm very bad in English but I'm going to try to explain my problem.

I have a python program and this program is a service.

chronologically:
1. I install my program like service -> it's ok
2. I start the service -> it's ok
3. I stop the service -> it's ok
4. I remove the service -> it's ok
5. I install a new version of my program like service -> it's ok
6. i try to start my new service but it don't start.

If I remove the new service and I install the old service I don't arrive 
  to start my old service.

If I launch my program like a process, the program start.

Is it possible that the service is badly remove?  How to make to check it?

I install my service with the command: "myService.py --startup auto 
--interactive install"

I remove my service with the command: "myService.py remove"

I start my service with the command: "net start pampa" (pampa is the 
service name)

I stop my service with the command: "net stop pampa"

Here the code of my service:

import win32serviceutil, win32service
import pywintypes, win32con, winerror

from win32event import *
from win32file import *
from win32pipe import *
from win32api import *
from ntsecuritycon import *

import log
import PampaClient
import time

class PampaService (win32serviceutil.ServiceFramework):

     _svc_name_ = 'Pampa'
     _svc_display_name_ = 'Pampa Client pour WinNT'

     def __init__ (self,args):
         win32serviceutil.ServiceFramework.__init__(self,args)
         self.hWaitStop = CreateEvent(None, 0, 0, None)

     def SvcStop(self):
         self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)
         SetEvent(self.hWaitStop)

     def SvcDoRun(self):
         import servicemanager
         servicemanager.LogMsg(
                 servicemanager.EVENTLOG_INFORMATION_TYPE,
                 servicemanager.PYS_SERVICE_STARTED,
                 (self._svc_name_, ' Youpi ?')
                 )
         programmePrincipal = PampaClient.PampaClient()
         try :
             programmePrincipal.main()
         except :
         shutDownThread = programmePrincipal.getShutDownThread()
         shutDownThread.setService(self)
         while 1:
             rc = WaitForMultipleObjects((self.hWaitStop,), 0, 1000)
             if rc==WAIT_OBJECT_0:
                 break

         self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING, 
5000)
         servicemanager.LogMsg(
                 servicemanager.EVENTLOG_INFORMATION_TYPE,
                 servicemanager.PYS_SERVICE_STARTED,
                 (self._svc_name_, ' Arret en cours')
                 )

         shutDownThread.shutDown()
finir
         while shutDownThread.isAlive():
             time.sleep(2)
         self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING, 5000)
         servicemanager.LogMsg(
                 servicemanager.EVENTLOG_INFORMATION_TYPE,
                 servicemanager.PYS_SERVICE_STOPPED,
                 (self._svc_name_, ' Youpiiiii c\'est fini')
                 )


if __name__=='__main__':
     win32serviceutil.HandleCommandLine(PampaService)


thank you in advance for your reponses,
