Please check it is not a bug.

Hello, Honoured Engineers!

I have a problem with this code in LabView 8.6.1 and 2009. I don't understand why an application hangs when I press a button.

All versions of LabView are registered and activated. And I know that in base versions there are problems with Event Structure so I've activated with Professional licenses.

(on the picture False case and Timeout case are empty)

If you wire 0 to a for loop it will run zero times. So the output is an empty array. Hence it will not contain the number 0, and the search 1D array will give -1 as output. You can track such errors by using probes. Debugging is an important art in programming. And should not be overlooked;)

Your button's mech action is 'switch until release'... change this and it won't hang.

Sorry I did not catch your problem. Shall never answer a posting before having a (large) cup of coffee first. And you are correct the control is locked up. I did a test with other types of mechanical action, and can see the same problem. So yes it is a bug

Yes, Coq Rouge, it seems a bug but where is it?

As You sad this code doesn't work too.

Hello, Jevon!

It doesn't hang when I change for-cycle with a constant array or when delete Event handler for a button.

[Coq_Rouge]

It has something to do with the event structure. Good luck finding out why.

Good Luck, Coq!

You should avoid using the event structure the way you have it here in the case statement. The event structure is associated with the control and locks the front panel (when the button is pressed) until the event structure has handled the event. I recommended changing the architecture.

I've rewrote the code, Jevon, as You advise.

It doesn't work.
