Here's one way, dunno if it's the *best* way... I've got 4 bitmaps defined with ids:
1200...1500. Each one is a progression of an
animation sequence.
// since comm is successful, animate the satellite icon
if (++SatelliteIcon>3) SatelliteIcon=0;
SatelliteIconID = 1200 + (100*SatelliteIcon);
DrawBitmap ( NULL ,SatelliteIconID,134,63);
where DrawBitmap is shamelessly plagarized (sp?) from I forget where, probably Neil
Rhodes book....

Subject: Form Bitmap
Maybe I'm blind but I can't find functions for what I intend to do in the
documentation.
I have a form bitmap and several bitmap resources. How can I dynamically
change the bitmap resource ID of the from bitmap, so that the bitmap
displayed changes? Before drawing the form, obtaining a BitmapPtr b and
setting b->flags.reserved works, but this surely isn't what I am supposed
to do, is it?
