Status of request VI using VI Server

Hello

I'm trying to understand how querry the status of a VI using VI server.

I want to know if the VI I call is already running or open.

Thank you

Dan

You can pass JUST the names of VI to a "ref open VI" and he will NOT return an error if the VI is already opened and loaded into memory.

Execution state property will tell you if it is running.
