    Detecting a keyboard wedge input


    I am wondering if this is possible:
    I want my users to have to scan their badge to enter my application. I am
    using a keyboard wedge. I need to detect that the input is coming from the
    wedge and not the actual keyboard. Does anyone know if this is possible?

    I don't believe it is. I thought the whole point of a wedge was to enter
    keystrokes that the software can't tell is not coming from the keyboard.

    Normally, they can be configured to send a character string before and after the code.

    Re: Detecting a keyboard wedge input

    Hi,

    Perhaps, though there is no fool-proof way (IMO). This capability depends
    on the barcode scanner hardware, and even then...

    For heavy-duty applications, I prefer a barcode scanner that connects to the
    PC serial port. These cost a little more than ones that use a wedge.
    However, there is no confusion with actual keystrokes, and they will work
    regardless of where the user has placed focus. I have an example for this
    in my book (see below).

    Thank you! Yes, I was able to configure the scanner to attach a character
    to the output.
