arrêter/démarrer les services par VB script

J'ai pris le script visual basic suivant à partir du site suivant: http://www.itninja.com/question/how-do-i-stop-start-service-in-vbscript

J'en fais peu de changement dans cette VB ( annuler la fonction )

la cible de cette VB est au service de contrôle – arrêter ou démarrer les services

donc j'essaie par exemple d'arrêter l'Avertisseur services

Et je ne peux pas comprendre pourquoi le service ne s'arrête ou peut-être il y a d'autres questions? dans le script VB?

 '//   Name:    ControlServiceWMI
'// Purpose:    Controls services using WMI
'//   Input:    strComputer        - String    - the computer on which we want to       control the service. Null means local machine
'//           strService        - String    - the name of the service. If     blank,       the    function will use strDisplayName
'//           strDisplayName        - String    - the display name of the service.    If   blank, the function will use strService
'//           strOperation        - String    - the operation for the service: START, STOP, PAUSE or CONTINUE
'//           intWaitTime        - Integer    - nbr of times to loop (effectively, the nbr of seconds to wait
'//                             for 'strOperation' to complete
'// Output:    strError        - String    - contains error text, if operation fails
'// Returns:    True/False
