Use ProcessStartupInformation in JScript or javascript   

I am trying to start psexec in a hidden window but can't seem to get it 
right. When I run the script (actually a HTML Application) I get Error: 
Object doesn't support this property or method. The line number matches the 
line where I'm trying to set the property. If I set it to "null" no error and 
the script works but the window is not hidden.

   var strComputer = ".";
   var strCommand = "psexec \\\\rmtserver cmd.exe /k";

   var objWMIService = GetObject("winmgmts:\\\\" + strComputer + 
"\\root\\CIMV2");
   var objProcess = objWMIService.Get("Win32_Process");
   var objInParam = 
objProcess.Methods_("Create").inParameters.SpawnInstance_();
   var objStartup = 
objWMIService.Get("Win32_ProcessStartup").SpawnInstance_();
   objStartup.ShowWindow = 0;

   objInParam.Properties_.Item("CommandLine") = strCommand;
   objInParam.Properties_.Item("ProcessStartupInformation") = objStartup;

   try
   {
      var objOutParams = objWMIService.ExecMethod( "Win32_Process", 
"Create", objInParam );

      if ( objOutParams.ReturnValue  == 0 )
      {
         g_intProcessID = objOutParams.ProcessId;
         alert( "intProcessID: " + g_intProcessID );
      }
   }
   catch ( e )
   {
      var msgText = "RemoteAccess.hta:\n";

      if ( typeof( e.num) != "undefined" )
      {
         msgText = e.num + "\n";
      }
      
      msgText += e.description;

      alert( msgText );
   }

Try:


objInParam.Properties_.Item("CommandLine").Value = strCommand; 
objInParam.Properties_.Item("ProcessStartupInformation").Value = objStartup;

Thanks urkec. That worked. I guess since the CommandLine parm is a string 
specifying Value isn't needed but since ProcessStartupInformation is an 
object of type Win32_ProcessStartup it has to have Value specified. It would 
sure be nice if the examples and documentation on MSDN more clearly depicted 
this.

Thanks again...
