I set up the barcode device to add a suffix to the data being read - something that will never be part of the data. In my case I chose the dash sign ( - )

Then in the etextbox_change d event I just check whether the input box endswith "-" and if so I chop off the "-" and copy the contents of the texbox to wherever.

My problem is that the device is suddenly adding an extra "S" at the end,...
