Sorry for the last msg, there was an error in my sentence..here's the update:
My main application is a big tab control (containing 5 tabs)
On the 1st tab, I wish to display (call) a VI (this VI is a standalone motor control that I built in the past).
The idea here is to have only one Labview window on the screen. I want the user to click on the tab in order to control the motor.
How can it be done?
