Variable scope, how to set a variable from subvi??

[Hüseyin]

Suppose we have a vi name  "example.vi" and this vi calls anothe vi name "SUBVI.vi". eaxmple.vi has an indicator name Boolean1. I want to set Boolen1 WHILE (this is very important) SUBVI is executing.

I attached the above vi's. Can you suggest a way to solve this problem?

Well you can update the reference to the boolean control in the mainVI from the subVI. Have a look at the following KB aricle:

How Can I Update the Changes Made to a Control/Indicator from a SubVI on the Main VI?

So, when the subVI starts execution, set the boolean to TRUE and when done, set it to FALSE.

Thanks Adnan, that's what i want 🙂

Are you Turk? your name is used in Turkish.

No, I am not Turk. 'Adnan' is an Arabic name and since Turkey is majority Muslim (I do know it's officially a secular state), I would assume most names over there would be similar to Arabic ones.
