What's confusing is your statement that you want to do this "without display the test stand program". You can minimize the TestStand UI to the task bar but if you don't want TestStand to be running, how can TestStand evaluate the result. Explain a little more please.
In the message body of your post, you just say you want to create a LabVIEW exe and pass the results to TestStand. What I would recomend is that instead of an exe, you create a dll and use TestStand's DLL adapter to call it and return the results. TestStand will evaluate it and do the logging.
