loop break hot-key

[mkh113@rsphysse.anu.edu.au]

Dear Forum,

My collegues and I are new users of Labview and we were wondering if
there is a way to break an (accidently programmed) endless while loop.
The problem, in its simplest form, is a while loop with a dialog box
inside and the output of the dialog box tied to the while loop's loop
contidion box. I've played around with it a little, but the only way I
can find to break the loop is Ctrl-Alt-Del, which forces the closure of
Labview altogether.

Kind regards
Michelle Harmos

Does the dialog box have two buttons? The cancel button yeilds a False
output, and if that's the only thing connected to your loop condition, it
should halt. If there are other conditions hooked up to your loop
condition, put a case statement after the dialog box output to control
them.

If this happens in development hit Control-. (Control and the period
key). This will stop the program. You can also use this to stop a program
that has been coded to Exit LabVIEW when a Stop button is pressed and there
are no menus.

Hi,
Try this: press + . (LabView shortcut to
stop a program) and maintain pressed. Answer the
dialog box with the mouse, the vi will perhaps
stop.
In some cases, you may answer many times the
dialog box before the vi stops.
I think that the VI must accept to be stopped by
the user (Vi Configuration menu: show stop button
or something)

Laurent.
