Hello All -

One of my clients has a 'symbol scanner' plugged into his USB port

He places the cursor in a field (say Stock number) in a PB window object, and when he scans a barcode from a paper or another application on-screen, he wants the value read by the scanner to populate in the field which has the cursor

I believe the scanner has a port number and the data could be read from this port? How do I read data from this port? Or is there a way to do it without listening at the port in PowerBuilder code? Like a Windows DLL that I need to add a local/global external function for, in PB?

Any help is sincerely appreciated, thank you!
