    Hi folks,
    I am writing a db for shopping and I planed to use those barcode guns instead of entering goods code by operator, if anybody has information about how to do that, I appreciate to let me know.

    It works just like a keyboard in most cases, so you don't have to do anything special for the database design.

    depends on the design of the barcode device.
    some are serial devices, so you have to read the serial port, which can be a bit of a pain in access if you need real time continuous comms.. it shouldn't be in Access for a barcode reader

    soem are keyboard wedges. ie the computer sees the input as if uit cam e from a keyboard. the only real issue here is making sure that you correctly intercept the keyboard input. usually that means no more than making sure the correct control has the focus. often you do that by selecting a button on the screen (captioned say: "activate scanner") which sets the focus to the correct control


    if you have a choice get the keyboard wedge style scanner.

    You can set up the barcode gun to add an end-of-barcode message (a TAB or return) as well. If you'll have several barcodes to read for a given page, this is useful for navigation.

    Also, a company named TALTech makes a software "Wedge" that causes serial port barcode input to be treated as keyboard input by your system, and adds many options (like the end-of-barcode character padding)
