Yes. By any method that you would use to pass any other data that wasn't a reference to another VI,  (connector pane, queues or notifiers, action engine ....)

Yes, it can be passed. You can use the connector pane of your SubVI to link the Ref Ctl, to make it accept the Refnum constant/control from the MainVI.

To create the exact type of the Ref Ctl in the SubVI, there is this small trick.

First create the Refnum constant for a Ctl in your MainVI. Then rt-click >> Create a Ctl for this Refnum.

Now, copy it to your SubVI, you ll get the same type/kind of Ref Ctl you need to pass from the MainVI to the SubVI.

hi,

I have a Test button in one vi, in which i am making it invisible programmatically, thats our requirement.

i have one more vi, in which there is a button called main menu. whenever i click main menu button it should go back to the vi and it should make the Test Button visible.

i am going back to vi, but i am unable to make the test button visible. How can i do this?

InAdvance Thanks

Hi Soundarya,

make it visible the same way "i am making it invisible programmatically", i.e. using the same property node...
