Is it possible, when i call a vi from within my code, to pass to it parameters as input and to return some values too?

Hi There!

I am currently calling a vi from within my code. However, what i would like to do, is to pass it 2 int values when i call it and for it to return 2 int values when it is done!

Any advice on how i can do this please.

Thanks.

If you have two controls and two indicators on the subVI, just wire them to the subVI's connector pane.

Hi there!

Thanks for your reply. I have had it the way you mentioned.

This is the scenario, i have a main vi, lets call it Main.vi and from here i call another vi, lets call it X.vi. The X.vi can take parameters and return values.

The problem is that when i use the Open vi reference and use its property node's methods to open and run the vi, i do not know how to pass parameters to the X.vi and how to get return values back from it when it closes.

Please advise.

Thanks again.

Hi Matrix,

is there a reason you do it this way? By Ref (it is called dynamically loading)

If you place the VI directly on the BD of a VI you can just wire things up.

Now if you need dynamically loading. hoover the open VI-ref function and right click on the type specifier and select create constant. Then right click browse, browse to your VI. Now you have the connector pane.

But if I were you I just use VI directly, because you'll keep connections active between the two VI's

Hi again!

Thanks for your advice. I dont know why i wanted to use the dynamic way... But for the time being, it seems as if the normal static way should work.

Thanks again!
