    First you need some data (like a picture).
    Then transform the data into a line.
    Then devide this line in areas and each
    area should reprecent a number. Add these
    numbers strings together and then parse to
    a long and return the long.

    I haven't done this at all and I have no
    idea what I am taking about but this sound
    rather good to me.

    Hope you understand.

    The most easy way is to buy a device that can read a barcode and that you can connect to your computer. Otherwise, you will have to make your own reader.
    Then you can read out your hardware port with software, or when you are lucky, a driver is provided with the reader.
    Anyway, your reader should come with documentation about what the reader returns, signals and stuff.
    If you make your own reader, you can define it as you want.

    I recommed you to download this free online barcode reader for simple barcode scanning. You just need to pass your target barcode image file and barcode type to "BarcodeReader.readBarcode" method. Then, this [link=http://www.keepautomation.com/guide/dotnet_barcode_reader.html]C#.NET Barcode Reader Control[/link] will immediately scan & output all barcodes found.

    This thread is so old!!!!!!!!Ok, actually, nowadays it is quite easy to read barcode, just use a barcode scanner, like [link=http://www.onbarcode.com/products/java_barcode_reader/]Java barcode scanner[/link], [link=http://www.onbarcode.com/tutorial/csharp-barcode-reader.html]C# barcode scanner[/link], etc.

    What you need is a barcode reader. There are hardware ones(mostly handheld style) and software ones(installed on PC or smartphone). You can complete integration with the guide and then start scanning and decoding barcode images. In most case, the data in barcode images will export as plain text.
