Close VI reference and memory

[labmaster]

I want to post a message for counting time infinitely by while loop.

If I load this while loop by VI reference on a main program,

do I have to stop the while loop when it close (by using property nodes of close FP and close VI reference)?

You should stop the program execution before closing the panel.  Closing the Front Panel does not automatically stop execution.

You can set the auto dispose (reference) to true, so it will clean up the reference.  But simply closing the Front Panel will not stop the VI from running or remove it from memory.
