I recently acquired a Metrologic Barcode scanner (USB port), as everyone already knows it works as a keyboard emulator out of the box.

How do I configure the scanner and my application so that my app can process the barcode data directly? That is, I don't want the user to focus on a "Text field" and then process the data when the KeyPress event fires.
