Peter, you could also put a hidden button on your form. The scanner could be
programmed to trigger the button which would then grab the data being scanned
and allow your code to process it.

Hi Dougie
This is in fact what we do at the moment. (In fact it’s so simple I just use
the 4D “Request” function to capture the barcode).
The only thing that would make a marked improvement while not complicating
things too much would be for the capture to auto-enter itself after the scan
Peter,
As Pat said a barcode scanner is nothing more than an input device so it
operates like a keyboard. So an enterable text area is the easiest way to
manage the input.
We do an awful lot of barcode processing in our EPOS app as well as in our
main ordering system. It is about managing
Thanks Jeff. Very useful information.
I also checked out your even more detailed responses on last year’s thread
about this which were very informative.
Regards
Peter

If you want to use a USB barcode scanner and still have complete control, you
can use ON EVENT CALL to manage this. You'll need to program a prefix character
and a suffix character into the barcode scanner, and have your ON EVENT CALL
method watch for these characters to determine what to do.
