Examples

The following example uses the ServiceController class to check whether the Alerter service is stopped. If the service is stopped, the example starts the service and waits until the service status is set to Running.

// Check whether the Alerter service is started.
ServiceController^ sc = gcnew ServiceController;
if ( sc )
{
   sc->ServiceName =  "Alerter";
   Console::WriteLine(  "The Alerter service status is currently set to {0}", sc->Status );
   if ( sc->Status == (ServiceControllerStatus::Stopped) )
   {
      // Start the service if the current status is stopped.
      Console::WriteLine(  "Starting the Alerter service..." );
      try
      {
         // Start the service, and wait until its status is "Running".
         sc->Start();
         sc->WaitForStatus( ServiceControllerStatus::Running );
         
         // Display the current service status.
         Console::WriteLine(  "The Alerter service status is now set to {0}.", sc->Status );
      }
      catch ( InvalidOperationException^ e ) 
      {
         Console::WriteLine(  "Could not start the Alerter service." );
      }
   }
}

// Check whether the Alerter service is started.

ServiceController sc  = new ServiceController();
sc.ServiceName = "Alerter";
Console.WriteLine("The Alerter service status is currently set to {0}",
                   sc.Status);

if (sc.Status == ServiceControllerStatus.Stopped)
{
   // Start the service if the current status is stopped.

   Console.WriteLine("Starting the Alerter service...");
   try
   {
      // Start the service, and wait until its status is "Running".
      sc.Start();
      sc.WaitForStatus(ServiceControllerStatus.Running);

      // Display the current service status.
      Console.WriteLine("The Alerter service status is now set to {0}.",
                         sc.Status);
   }
   catch (InvalidOperationException)
   {
      Console.WriteLine("Could not start the Alerter service.");
   }
}

' Check whether the Alerter service is started.

Dim sc As New ServiceController()
sc.ServiceName = "Alerter"
Console.WriteLine("The Alerter service status is currently set to {0}", sc.Status)

If sc.Status = ServiceControllerStatus.Stopped Then
   ' Start the service if the current status is stopped.
   Console.WriteLine("Starting the Alerter service...")

   Try
      ' Start the service, and wait until its status is "Running".
      sc.Start()
      sc.WaitForStatus(ServiceControllerStatus.Running)
      
      ' Display the current service status.
      Console.WriteLine("The Alerter service status is now set to {0}.", sc.Status)
   Catch 
      Console.WriteLine("Could not start the Alerter service.")
