exit from a while loop in sub vi

this occurs twice

Hallo,

Can the use of occurrences solve this problem?

The Main program can create an occurrence which can be passed to the
sub-VIs. Upon pressing the button to cancel the loop, the occurrence can be
set, instantly transmitted to all other VIs sharing which were passed the
same occurrence. Of course a small handling routine has to be written (say
a sequence parallel to the executing while loop waiting for the occurrence
and then setting the exit parameter to "true") but this is trivial.

I have checked this with a small program splitting an occurrence to three
seperate VIs and it works.

If you want, I can send a cop
y of it.

It may well be possible with notifiers or something else, but I have far
less experience with them.

Hope this helps

Shane

The notifier is probably better than occurence at this case - than it is not neccessry to write a parallel sequence.

The use of notifier is very simple, just follow an example in Help/Search example -> Advances -> Execution control -- Synchronization -> SubVI notification.

Good luck
