VB.Net events: test if sender is another sub or function

Question

Is there any way to test if an event linked to a control is triggered by the program, rather than by user action?

I have a scroll bar which fires events when the user moves it. I want to be able to move the scroll bar programmatically elsewhere in the code without sending these events. i.e. events should only fire when the user interacts with the control, not when I move the control via code.

I also have radio buttons and numeric up/down controls I'd like to b able to do this with.

Thanks

There maybe better ways to do this but a quick way would be to use a boolean variable that you set when you are programmatically scrolling and unset it when you're done. Then in your event check that before executing the logic.

If IsProgramaticScrolling = False Then
    ' Do whatever it's supposed to do when your program isn't
    ' scrolling via code.
End If
