How can I pass a Vi reference back to TestStand

[sylviane]

From TestStand, I call a first VI which launchs a second one and get back its VI reference as an output parameter.

Then, later I try to use this VI reference with an invoke node.

I have the error " Invoke Node in SetNumVar.vi LabVIEW:  VI Reference is invalid."

Have somebody an idea how I can memorize the VI reference to path them from one VI to another ?

Thanks,

Sylviane.

I don't believe you can pass a VI reference in that fashion any more, now that VI reference numbers are local to that execution instance.  Why not just pass the name of the VI as a string and open a new reference to that VI in SetNumVar.vi?

OK. You're right. It's working like that.

Thanks for your help.
