    Reading data from barcode scanner

    Hi,

    Can anyone please help me out with this project I have to do, I am a VB 6 beginner and I have a project which requires me to read data from a barcode using a handheld Symbol scanner and then link that data to an Oracle database, I've been trying to attempt this for weeks now but with no luck.... I would be eternally gratefull to anyone who could help me out with this.

    Thank you,

    Derek

    P.S. the manufacturer sample code is not useful

    If the scanner attaches to the serial port, you can use the MSComm control to read its input. If it's a "keyboard wedge" scanner, its input will appear as if it were typed at the keyboard; you may simply set focus to a textbox and the scanner's input will appear in the .Text property.

    THanks for your reply Phil, but the scanner uses a PS/2 interface, I did try the MSComm control earlier but no luck there.

    So I assume you plug the scanner into the keyboard connector on the PC? Try setting focus to a textbox, then doing a scan; the scanner's output should appear in the textbox.

    yes, the scanner is plugged into the keyboard connector on the pc. I tried to do a scan but it does not show any output in the textbox.

    I would double check that the scanner is installed and configured correctly, checking with the vendor's support dept as necessary.
