cancel event

[labmaster]

(See my attachment for my code.)

When B1 button is pressed and then run some routine inside while loop,
I would like to receive some event signal from other button(here cancel or any ohter method) to stop the while loop.

In attachment, please note the event of cancel button's value change is used to do something.

In a normal event structure, can I realize this?
Or Do I have to change the design pattern?

One major problem you have is that for the 'B1' event, you have it set to lock the front panel until the event finishes. Right click on the event and select 'Edit Events Handled by This Case' and change it. It's a checkbox on the bottom. In the 'B1' event, you could also wire the Cancel button straight to the conditional terminal. I don't know why you need a local.

It is against the spirit of an event structure to prevent it from breathing by stalling it with an inner loop. You can easily use the outer loop for everything by using and manipulating the timeout. Now any other event (e.g. pressing stop) can also react if needed.

See attached quick modification. (LabVIEW 8.2). 🙂

Dear,

As you told me, I wanted to update UI event outside loop.

altenbach, would you please give me other example in long execution time on B1 event?

Actually, I want to insert some routine to receive UI event during the while loop in B1 event.

altenbach, sorry..

I understand what are you talking about.., but the timeout was reserved for other periodical routine in 1 sec period.

Any idea for my situation?
