    your post is not very specific, connect to the barcode reader through Rs232 or usb, im not sure how to deal with a usb connection in c but rs232(serial) is simple. Open the port as a file, you can set baud settings etc. The bar code reader specification will tell you how the reader communicates. then its just a case of recieveing the packets it sends into your program. Get the technical specification for your reader and it will be more clear

    Iain is right,such apps. require knowledge of hardware.
    That aside,u can find barcode reading programs at .
    A shareware program which reads barcodes and interprets them can be found at .
    U can also post ur needs at .Maybe some programmer there might have the solution(but it'll cost u big bucks.)
