This site may vanish anytime soon, according to the maintainer, but it hasn't been updated in a year or so. Perhaps it will sit around forever.
Disregarding its age, the site contains a lot of academic examples on how to use OpenGL in Visual Basic. Academic because few have foundation in real life problems, but nonetheless they illustrate OpenGL very nicely.
An excellent introduction to programming OpenGL, both in general and using Visual Basic. The site is full of examples, documentation, and custom controls which all guide you through developing OpenGL applications.
