Don't post this under Quick Answers - if you got the code from an article, then there is a "Add a Comment or Question" button at the bottom of that article, which causes an email to be sent to the author. They are then alerted that you wish to speak to them.
Posting this here relies on them "dropping by" and realising it is for them.

But ... most barcode scanners are configured to emulate a keyboard by default, and you cannot tell the difference between scan data and typed data - Windows does not provide that information to applications at all.

The only way to do what you want is to reconfigure your scanner to provide "lead in" and "trail out" sequences that your app can detect and use to force the input to a specific textbox, then action it when complete. To find out how to add those sequences, you need to consult the scanner documentation, or talk to the manufacturers as the process is different for each manufacturer (even even for each model).
