Capturing a front panel menu selection in a SubVI

[Kenneth.Miller]

All,

      Title is pretty descriptive, so i've got a subvi that's running pretty much in a while loop and I want a menu selection from the parent VI to be able to cancel it. What i've tried so far is passing the reference to the front panel menu and then trying to detect a valuechange/mouse click/ selection etc in an event loop in the SubVI. The problem is it doesn't look like the front panel menu registers the change until after the SubVI finishes executing. How can I fix this?

Regards,
Ken

Hi Ken,

I hope you are doing well today! Before I attempt the answer your question, I need just need to clear a few things as to what you are trying to do. Are you trying to stop the while loop in the subVI from the parent VI? And, what’s the purpose of using a menu selection? If you can post a simple example, that would be great.

Got it working if anyone cares to see.
