Gui Development Question

[Benet]

I have developed a GUI that uses a menu cluster in a while loop that looks for button presses. Also located in this main loop there are VIs that send and receive info from our target hardware each time around around the loop. I have the standard case structure in the main loop that does the action for each button press. Within the case structures are VIs which pop up and show sub-menus for particular sets of command choices. These sub VIs have their while loops and case structures and exit buttons. My question is this:

How can I get the command selected in a sub-vi back to the main VI without exiting from the sub-VIs menu. Is this a case for parallel while loops? I'm a little rusty with my LabView so any help is appreciated.

Thanks,

Mary Ellen

Hello, Mary

You can use vi-server method "Get Control Value" from your main.vi when sub.vi is running. Only your sub.vi must be running dinamically and parallel to main.vi.

Look attached vi.
