Thre is any tutorial that explain how to create two opengl windows ? Possibly using Nehe's code ? Thanks

Two Win32 windows or two OpenGL rendering contexts or maybe two OpenGL RC's in the same Win32 window?

Hi, two Opengl rendering contexts !

multi-window code for lesson 42

(a google search for 'multiple windows nehe lesson' would have given you this as the first result)

Thanks very much, next time i'll google before asking ...

ohh I'm not complaining :)
having questions like this does obviously help everyones knowlege, it's just I guess I wanted to stress that google is a rediculously powerful tool. Just you need to know exactly the words that would get the best answer.
For example, "multiple window opengl source code" would get you absolutly nowhere in google. It's just I happened to remember that someone updated the viewport lesson to do multiple windows... So that was the first thing I googled.
