Barcode scanners nearly all ship set to act as a keyboard, so when you scan a code the characters are fed as keystrokes into Windows keyboard queue. Unfortunately, Windows does not record the source, so once the scan is started you cannot tell if it was typed on one of the (many possible) keyboard devices attached to the system, or scanned.

To get round this, most scanners can be set to provide "lead in" and "tail out" sequences that you can identify in your software to say "barcode coming", and "barcode ended" and divert the data anywhere you need to.

But ... each manufacturer (and sometimes even model) needs a different process to configure these. You will have to speak to the manufacturer of your specific scanner to find out how to set the sequences.
