Well, you could use CreateCompatableDC to get a device context that is
in memory, not on screen, and then bitblt that onto the screen for the
animation effect. Not as fast as page switching but it should do the
trick (unless you have very large images to animate).

Yes. Write the Windows and the DOS versions, then use the DOS version
as the stub of the Windows program. The "stub" of a windows program is
usually a very short .EXE that says "This Program Requires Microsoft
Windows" but it could be any program , including a full-blown text
version of your program.

Not anymore. Windows 3.0 does not have a run-time version.
