    Re: GDI+ and Rubberband/Selection Rectangle

    I for some reason didn't think you could mix GDI and GDI+

    GDI+ and Rubberband/Selection Rectangle

    I cannot find how to draw a simple selection rectangle (rubberband) using
    GDI+.

    This should be a simple thing, but I'm beginning to wonder if it is even possible.
