Does the condition evaluate to true? How do you know timer event is not firing? Do you have a breakpoint in there?

Yes it does. I did figure it out thought. I used an Invoke and a timer .start() to trigger the timer.

me.Invoke(New MethodInvoker(Addressof me. timer.start))

How can I close this now?

I found the solution myself by using the invoke method.
