Abort Sub VI

[Kenneth.Miller]

    All,

      What I'm trying to do here is abort a sub vi that is running an event loop. The problem is the front panel locks up while the SubVI is running and I can't generate the abort event. Code is attached. Thanks for the help.

In your Main vi, edit the event case for the Run value change, and uncheck the checkbox next to "lock front panel until the event case for this event completes".

In addition to tbob's suggestion it is generally not a goood practice to put any code inside an event structure which might take longer to execute than the minimum time between events. If you run the subVI in parallel to the main VI, the main can continue to respond to its own events.

If all you are trying to do is to stop the subVI from the main VI front panel, there are much easier ways than nested loops and event structures: Notifiers, queues, occurrences, action engines, global variables, ...
