execute a command when labview is stopped

[Monse]

my issue is that I have a CompactDAQ with a NI 9485 solid state relay module... I've developed my program and it works fine (well not fine or I wouldn't be writing this) except that the relays do not go back to a default open state when the program is shut off... the relays stay in whatever state they were in when the program was active.  This is bad for me because the relays are supplying power to some devices.... so I was wondering if there was anyway that when someone closes the labview program (not through the stop button the kills the main while loop but actually stops the program) that the relays can be set to some default state every time?

Thanks,

M

There should be no way for a user to hit the abort button or exit the app except with your front panel Boolean. You can go to VI Properties>Window Appearance>Customize and hide the whole toolbar and disallow the user to close the window. You could also trap and discard the 'exit' with an application close? and panel close? evens if you are using an event structure. There's shipping examples called Event Conditional Stop and Event Tracking that you should look at.

So please follow the suggestions Dennis gave!!

Just for the record, I believe the Ed Dickens was the origin of that quote. Please see here.
