    This depends on the type of bar code scanner, and the type of bar code.

    Is it a serial port scanner or does it use a keyboard wedge?

    If it uses a serial port, use the mscomm control to read data from the serial port.

    If it is a keyboard wedge, treat the bar code input as keyboard input.

    Are there any embedded characters in the bar code data used to identify the data field? If yes, you will need to parse the bar codes to determine to which data field the bar code belongs.

    If the bar code is a 2-d barcode symbology, there could be hundreds, or even thousands of bytes of data in the bar code data stream that you will need to parse.

    I suggest you take a look at Russ Adam's Bar Code 1 site.
