Re: Display DDS -- MIDRANGE-L

Another approach I've used is to configure the scanner to add additional characters to the scan. I configured it to add an F2, then the scan, then press ENTER. This allows the program to bring up a window with a large field to receive the scan (and make sure the cursor is positioned in it) and then the program gets control when the scan is completed.

in your situation, the program could show the barcode as a series of output fields and use substrings to break it up across multiple lines. Since the F2 is sent automatically and brings up a different screen, any time they scan, it'll go to a different screen anyway.

That said, replacing 5250 with other technologies where you don't have to resort to the "keyboard wedge" approach of scanning is even better.

Thanks all..

Yes, this is a "wearable" RF device... 6-8 rows and maybe 20 columns.
I have a larger field that goes off the screen.

But in this case, I need the user to see the right-most 10 characters (its an SSCC number from a barcode) to identify the label they just scanned. The first 10 characters will not be different for the individual job.

I ended up just creating a separate field for the screen.

Eventually, I'll reuse this code for a browser app.

Thanks!

My exprience with scanning guns is that even though the user can only see a small part of the screen (typically around 16 columns) the rest of the screen is still there. Sometimes the scanner can scroll right/left to see the rest of it.

So you could just define a 20 character field and have only 6 characters visible (Without scrolling) on the scanner screen. I did this quite often back-in-the-day.

Scanning application on very small screens where I need to display a portion of a 20-digit barcode.

I was wonder if there is a way to "overlay" a hidden field.
I could store the entire value in a hidden field, but only display the last 6 characters.

Is there a way to do that? Or is it simpler to keep track of it in the backend program?
