Problem with ServiceController

[northstar7]

I'm using a ServiceController to try to stop and start a service. For development, I've been using the Apache service to experiment with.

I have a simple windows form in vb.net with a start and a stop button, along with a servicecontroller added to the form.

The start button calls ServiceController1.Start and the stop button ServiceController1.Stop. Each works individually.

However, if I start the service with one button and then wait and try to stop it, it doesn't do anything. Or, if I stop the service with the stop button and then try to start, again nothing happens.

If I close the application and then reopen it, it will either stop or start the service. But not stop AND start.

Do you have any idea why this would be?


Here's the code:

    Private Sub btnStartService_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnStartService.Click
        If (ServiceController1.Status.ToString <> "Running") Then
            ServiceController1.Start()
        End If
    End Sub
 
    Private Sub btnStopService_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnStopService.Click
        If ServiceController1.Status.ToString <> "Stopped" Then
            ServiceController1.Stop()
        End If
    End Sub

Maybe the .Status property is not reporting correctly??

Try commenting the "if" conditions just for testing. That way if you hit 'Stop' it tries to stop no matter the Status. If that works, you know the problem is related to the Status condition or the way you are testing it.

Hi, thanks for the reply. You're right. It needed a ServiceController.refresh.

That fixed it.
