Query VI status using VI server

[ASTDan]

Hello,

I am trying to figure out how to querry the status of a VI using VI server.

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

Thanks

Dan

You can pass JUST the VI name to to an "Open VI ref" and it will NOT return an error if the VI is already open and loaded into memory.

The execution State proprty will tell you if it is running.
