    Linker Errors

    I have a dll Iím trying to add functionality to, this file already opens a dialog window. I want to call another dialog. I want to call another dialog in the constructor of this one, which I would think nominally is really easy.

    resource editor>add resource>new dialog
    then I added the buttons and edit boxes I wanted. Then right clicked on the dialog in the resource editor and added a class for it. So far to this point everything built fine.

    Now:

    Linking...

    Any idea what this meansÖ. It seems to be the same thing over and over.

    check that the IDD_ for the two classes is different. Check any similarities between the classes that might confuse the compiler
