yes and no.  yes, you can call all the opengl api
functions in the dll files.  ****BUT****, the functions
for creating a window and assigning that window as the
display of the opengl graphics, which is part of either
the glaux stuff, or the toolkit stuff, are not
available as dll from microsoft.  they are only
available as static linked files (lib), and many people
have even reported problems using these files with
compilers different from vc++, because of format differences
between vendor's lib files.
  however, i bet there are some tools out there, ie ocxs,
that allow the use of vb with opengl.  but then, mixing
vb and opengl is like putting a 250 hp engine on a
bicycle, vb4 is so slow that it eliminates the speed gain
provided by opengl.
  any comments, you opengl gurus out there?
