Let's position this.

If you want to produce moving video on the screen then DirectShow is the
way to go. If you have a source of bitmaps that you want to display in
sequence (like a cartoon) then see the push source samples. This will
allow you to build a graph showing Device Independant Bitmaps (DIBs!) fery
easily (well, for DirectShow!).

If you have a bitmap (DIB) in a file that you simply want to show on the
screen once (like the background of a form, for example), then the easiest
way is to use an ActiveX control to do it! VB and DOTNET have quite a few.

If you have some need to do it via a low level language then you need to
look up things like Device Contexts DIB StretchDIBits and stuff like that
IIRC the SDK Docs section on bitmaps provides the information with no more
than the usual obscurity!
