Hi,

I'm using a picture box/image box combination with vertical and horizontal scroll bars for opening and scrolling through a bitmap. I use the picture box and a mousedown event for digitizing coordinates. Problems are coming up when I want to zoom into a bitmap. The scrollbars have a limitted size and when the bitmap becomes too wide/height, I can't scroll any further. Any suggestions for zooming in/out and keeping the internal coordinate system for a mousedown event ??
