    You will have to subclass your textbox and process WM_HSCROLL and WM_VSCROLL messages.

    Re: Help with ShowScrollBar API

    Here is an example of how to do it for the vertical scrollbar and a picturebox

    You'll have to add code for the horizontal.

    You'll also have to add code to move the picture once the scrollbar position has been changed
