Barcode scanners are really easy. They will automatically scan into any textbox. You don't even need to write code.

Most scanners are shipped configured to act as if they were keyboards and will generate keystrokes for the Article Number you scan as if you have types it on a regular KB.

That's where the good news stops: you can't tell is the data came form a KB or the scanner, so unless the input focus is always in an input box you will not get the code to read or know where it starts and ends.
You can get round this by configuring the scanner to provide "lead in" and "tail out" sequences, but you will need to talk to teh manufacturers to find out how to do that as it varies from model to model.

Solution 2

Most barcode scanners are what's called a "keyboard wedge". Whatever they scan gets "typed" exactly as if it were a keyboard. So, whatever textbox has the input focus at the time the scanner is used gets whatever the scanner "types".
