Opengl Active X Control

I saw a link on the main page about how to imbed an opengl scene into an active x control, but the web sight was not very helpfull to me. I dont use the language he wrote in, and he did not go into details about how he did what he did. Can some one tell where to find out more info on Imbedding opengl scenes into active X controls. Up till know I have been using wildtangent to do this sort of thing, but its based on direct x (YUCK), and it requires a fee to publish, so If I could write 3D web content with opengl, i would be extatic, any suggestions??

oh yeah, i use C++ to write in if that helps at all.
