Trying to Stop a service and restart another service in VB

Hey guys I'm trying to stop one service and then restart a different service.

Right now I have this code to restart a service

Public Sub RestartService(ByVal myServiceName As String)

    Dim DataSource As String = TextBox1.Text
    Dim sStatus As String
    Dim myController As ServiceController

    myController = New ServiceController
    myController.MachineName = DataSource
    myController.ServiceName = myServiceName

    TextBox2.Text += "Stopping service """ & myServiceName & """...." & vbNewLine

    If myController.Status = ServiceProcess.ServiceControllerStatus.Stopped Then
        TextBox2.Text += "Service """ & myServiceName & """ is already stopped" & vbNewLine
    Else

        Try
            myController.Refresh()
            sStatus = myController.Status.ToString
            myController.Stop()
            myController.WaitForStatus(ServiceControllerStatus.Stopped)
            TextBox2.Text += "Service """ & myServiceName & """ stopped..." & vbNewLine

            TextBox2.Text += "Starting service """ & myServiceName & """...." & vbNewLine
            myController.Refresh()
            sStatus = myController.Status.ToString
            myController.Start()
            myController.WaitForStatus(ServiceControllerStatus.Running)
            TextBox2.Text += "Service """ & myServiceName & """ started..." & vbNewLine
        Catch exp As Exception
            TextBox2.Text += exp.Message
        End Try
    End If



End Sub

And this one to Stop a service:

Public Sub StopService(ByVal myServiceName As String)

    Dim DataSource As String = TextBox1.Text
    Dim sStatus As String
    Dim myController As ServiceController

    myController = New ServiceController
    myController.MachineName = DataSource
    myController.ServiceName = myServiceName

    TextBox2.Text += "Stopping service """ & myServiceName & """...." & vbNewLine

    If myController.Status = ServiceProcess.ServiceControllerStatus.Stopped Then
        TextBox2.Text += "Service """ & myServiceName & """ is already stopped" & vbNewLine
    Else

        Try
            myController.Refresh()
            sStatus = myController.Status.ToString
            myController.Stop()
            myController.WaitForStatus(ServiceControllerStatus.Stopped)
            TextBox2.Text += "Service """ & myServiceName & """ stopped..." & vbNewLine

        Catch exp As Exception
            TextBox2.Text += "Could not stop service """ & myServiceName & """" & vbNewLine
        End Try
    End If



End Sub

But when I try to click this button, it only stops the first service and it doesn't restart the second service.

Private Sub Button19_Click(sender As Object, e As EventArgs) Handles Button19.Click

    If MsgBox("Are you sure you want to restart Spooler Service?", vbYesNo) = vbNo Then Exit Sub

    StopService("LPDSVC")


    RestartService("Spooler")

End Sub

What am I missing inbetween stop and restartservice?
