Thanks for replying.
Yes, read from the scanner. I would like to be able to read a bar code. What happens after that, connecting to a back end, looking up data, flagging a record, etc. I know how to do on other languages and I think I can figure it out. But I am stuck right now on trying to read from the scanner. By that I mean get the bar code value. I found examples that use the camera, but I want to use the bar code scanner.
