Hi all, I just ported my program from win32 to MFC. I am using keyboard input for zooming in/out the scene, and capture keyboard input via OnKeyDown handler. But the zooming action is intermittent - not smooth, unlike the mouse. I also encountered this in win32 version, but was able to overcome by handling keyboard input in WinMain rather than in WndProc. How can I solve this in MFC? I guess we are not able to edit the WinMain procedure? Thank you for your attention, --Kemal

I guess I can accomplish it by holding a keyZoomDown boolean and continuously increment/decrement the zoom parameter in the main messaging loop. But where is the main messaging loop in an MFC application?

MFC is event driven, there is no main loop. You''ll need to set up a timer. You may want to just use pure Win32 and ditch MFC altogether.

There is a way, and i'll post it as soon as i get back (tomorrow) as i don't know how i did it right now. What i made was a free look view in which you can move when you press the left mouse button using w/s/a/d .

EDIT: And the main messaging loop for an MFC window is WndProc
