Hello everybody, The following code worked well untill we upgrade to TC 12. It is not only this specific piece of code, it's all calls to GetObject which fails. Whatever kind of call of Get...

    Ok, got it !

     

    So, the correct way is to always give the username and password parameters on ConnectServer but keep them to empty string if you connect to localhost.

     

    Here the full code of the working method:

     

      /**
   * <a id="services.getService"></a>
   * Récupérer un objet de type Service
   * @function
   * @param {string} ServiceName - Nom du service à rechercher
   * @param {string} [Host=Sys.HostName] - Nom de la machine hôte sur laquelle chercher le service, par défaut c'est sur la machine courante
   * @param {string} [UserName=''] - Nom d'utilisateur à utiliser pour la connexion a l'objet WMI, ne doit être valorisé que pour une machine distante
   * @param {string} [Password=''] - Mot de passe à utiliser pour la connexion a l'objet WMI, ne doit être valorisé que pour une machine distante
   * @returns {object} Renvoie l'objet Service s'il a été trouvé ou <b>null</b> si aucune service correspondant trouvé. En cas d'erreur un log d'erreur est inscrit
   */
  qa.services.getService = function (ServiceName, Host, UserName, Password) {
    ServiceName = qa.system.checkUndefined(ServiceName, '');
    var result  = null;
    if (ServiceName != '') { 
      Host     = CheckHost(Host);
      if (Host == '\\\\.') {
        UserName = '';
        Password = '';
            Host = '.';
      }
      else {
        UserName = qa.system.checkUndefined(UserName, '');
        Password = qa.system.checkUndefined(Password, '');
      }
      try {
        var locator = Sys.OleObject("WbemScripting.SWbemLocator");
        var objSWbemServices = locator.ConnectServer(Host, "\\root\\cimv2", UserName, Password);
        result = objSWbemServices ? objSWbemServices.Get("Win32_Service.Name='" + ServiceName + "'") : null;
      }
      catch(e) {
        qa.system.logExceptionByLevel(e, "getService(" + ServiceName + ", " + Host + ")");
      }
    }
    return result;
  };

     

     

    Txs for helping me.

Tried it but an error still occurs:

 

  Error: SWbemLocator
  Invalid parameter
   at Error (native)

 

It occurs on 

 

var locator = Sys.OleObject("WbemScripting.SWbemLocator");

In addition the initial code works well with TC 12 and Windows 7

 

The problem seems to be only with Windows 10 pro  (we tried on 2 VMs in Windows 10).

    OK, your error has now changed, apparently. Is it possible that the object in question is not present on your W10 box? I'm not familiar enough with the object to be able to know for certain but that seems to be my first inkling.

      Yes the object called exists (standard service object) because if we use the script with TC 11 on same computer under w10, it works.

       

      And this is not restricted to the service object, we use also the desktop monitor object or others and the errors are the same.

       

      If you try to use an inexistent object you'll have a relevant error message (this class doesn't exists)

        OK, perhaps I'm getting confused... by the statement I've quoted above, do you mean the script that uses "GetObject" or the script that uses "Sys.OleObject"? Because, if you are still using GetObject and you've converted your test to JavaScript instead of JScript, then you will get the error in TC12 simply because of the improper use of "GetObject" while the test will work fine in TC 11 because TC 11 isn't using JavaScript. 

        Sorry, just getting a bit lost in the conversation here.  In any case, if you are calling Sys.OleObject and getting the error you indicated and the object ClassID is present in the system, then the next thing is to look at the parameters... specifically, it seems that there is a parameter being passed to your locator object that is incorrect. Double check your value for "host" and make sure it is still legit.
