How to Update GL Version from 1.4 to 2.0?

My system is WinXp, and I use VC++6.0.My OpenGL Version is 1.4(use glew).How could I update my system to OpenGL 2.0.And How can I use GLSL in VC++6.0 environment.

I can’t find gl_FragColor and uniform and so on in my glew.h why?

>> gl_FragColor and uniform
Those are keywords used within glsl shaders, it is not OpenGL C code, but part of the string of a shader you pass to opengl.
