Anybody have any idea on how to do a zoom to fit. I would like to scale down my view to a printable size. Also where do I add in the code, in the on prepareprinting, onbeginpriniting or the onprint. How do I determine how much to scale down my view size by ?

Just a clarification. I'm using MC VC++ 1.52 . That is 16 bit Win 3.1 Application.

I think the OnPrepareDC is the best.
You can test the Isprinting function of CDC, change your window or/nd viewport origin change the map mode to MM_ISOTROPIC or MM_ANISOTROPIC to be able to use ScaleWindowExt or /and SetViewportExt to change the scale factor.
How to determine the right values is an other problem

I am drawing a schematic using lines and curves in my view. Changing the mapping mode causes the schematic to dissappear.
