I want to enhance an app based on the CScrollView class. What I want is to add zoom in, zoom out capabilities. With my basic understanding of the CScrollView class, it supports a changing Doc size, but a fixed View size (relative to the actual window size). Is there any way to make the view size "virtual" also? i.e., the window may be 50×50 pixels, but it displays a 100×100 region of the document. Obviously scaling of the drawing would be nescesary, possible during the DPtoLP and LPtoDP routines. Any ideas/suggestions?? I've done this before in an all Windows SDK app, but am wondering of an automatic and cool MFC method! I would like to think that this was thought of when the CScrollView class was born. Thanks in advance, BP
