WD-24 Break a While not/End loop.
July 18, 2020 12:45PM
Hello to you all,

I have a While not/end loop and I want to have the possibility to interrupt that loop.
Tried with "IF KeyPressed(kpEscape) THEN Info("Loop stopped.");BREAK"

Does not seem to work. Anybody with a better idea ?

Thanks for any assistance.

Best regards,

Aad

Hello Aad

It's been awhile since I have done it but from memory, the Multitask() function allow for the activty that is running to suspend for a micro second and nominated intervals and while the activity is suspended it will accept a keystroke. You might have to play with it to get it going or someone might have an example.

Regards
Al

Hi Jan,

I have no real code. It's just a standaard loop.
I want to make a ReIndex-module for several hundreds of files.
Was wondering if there's a way to interrupt that loop, because
it takes quite some time to finish.

Hreadfirst(File,Index)
While not h.Out(File)
IF KeyPressed(kpEscape) THEN Info("Loop stopped.");BREAK
Hreadnext(File)
End

Works pretty well here the way Al described with Multitask(-1) and a progress window with a cancel button

OpenChild (WindowProgress)
LOOP
MultiTask(-1)
IF WindowProgress.bCancelPressed
BREAK
END

-- your reindex here

END

Close(WindowProgress)
