in my VI a SubVI is called. It works in the background, but I want it to appear. After pressing OK or Cancel (= two of the buttons in the menu) it should disappear again.
1 - The sub vi has to stop when you press one of the 2 buttons
2 - Configure the subvi as follows : when you are in your VI (not sub VI) rightclick on your sub vi icon, click on "SubVI Node Setup" and then enable "Show Front panel when called" and "close afterwards if orriginally closed".
