Which one is more frequent? onDraw or onPaint?

[someTimeOnly]

I want to convert a 3d graphic win32 app to be MFC app. What limitations may I suffer?

I changed some parameters in onMouseClk of some functions that are in onDraw or onPaint, but their effects are not updated on the spot rather upon respective events. What should I do here?

for standard windows, not for standard or nonstandard controls you will always use OnPaint
