Interrupting Program Close

[DJDDA]

I'm designing VI's that operate high voltage devices. I don't want the user to be able to close the VI's without turning off the devices, because I don't want large, sudden voltage changes (or, y'know, devices that run at 3K volts for a week with nobody using them).

Thus, I want a VI that performs a shutdown operation before closing. A search indicates that I can make windows unclosable except by a VI's Off button; is there any other way to accomplish this?

(I'm using LabVIEW 8.5.)

Take a look in the example finder at the Events example called Dynamically Monitor VI's.vi it demonstrates how to capture the event of a user closing your program. So if they close it using the X in the top corner, it will capture this as an event, and you deal with it as you please. There was another thread about this very recently, I looked briefly for it but couldn't find it, maybe someone could link it for you if they find it.

Alright, thanks guys.

(I've also discovered that there's an option for this as an Event Structure trigger. Not sure why I missed that, but I think I may use it here.)
