I want to use one timer to momentarily (and separately) change the background image of some buttons as they are pressed. What I need to know is how to determine which "button" called the timer, so that only that button image changes. I thought I could do some IF Then's, but I cannot figure out how to check for the control that started the timer. Here is what I tried (to no avail):

    Private Sub Timer2_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer2.Tick
        If sender Is StopButton Then
            StopButton.BackgroundImage = WindowsApplication1.My.Resources.Resources.StopButton2
            Timer2.Stop()
        End If
    End Sub

I take it sender is not the right choice.....

Thanks for any help on this!

I think I'd probably use Timer.Tag to tell me what set the timer.

    Private Sub btnStop_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
        ' do stuff
        Timer1.Tag = "btnStop"
        Timer1.Enabled = True
    End Sub

    Private Sub Timer1_Tick(sender As System.Object, e As System.EventArgs) Handles Timer1.Tick
        Select Case Timer1.Tag.ToString
            Case "btnStop"
                'do stuff
            Case "btnGo"
                'do stuff
        End Select
    End Sub

Lar3ry,

Thank you for the suggestion of using .tag, I was unaware it existed! Thanks a lot!

Many controls have a .Tag property. I have developed the habit of looking for it when I need a variable that fits well with the purpose of the control. Glad it helped.

The sender object is the class raising the event.

Private Sub btnOne_click(sender As Object, e As EventArgs)
  'sender here is a Button wrapped up in an Object 
  'fully legal since it is derived from Object
End Sub

The sender object in your example was a Timer. Make sense?
