how to update opengl ?

My system is winXP. My graphic card is WinFast A400 GT TDH GeForce 6800 GT, which support OpenGL 1.5. But i don’t know how to install OpenGL 1.5. Actually, my OpenGL (OpenGL1.0)is the default one supplied by winXP.
How i do?
Thanks a lot

Here you go;f=1;t=004390

yes, i see.
but actually, but actually, i don’t know how to use the latest OpenGl driver.

i have installed the latest display card driver.
My display card is Nvidia GeForce 6800GT, which can support OpenGL 1.5. And its part about opengl driver is nvoglnt.dll.

Yet my system(WinXP) has a document opengl32.dll.

how to use nvoglnt.dll or OpenGL 1.5 in VC++6.0?

if I can’t use OpenGL 1.2 or above, I can’t apply so many function(such 3D) of OpenGL!

How can i do?

Could someone tell me ?

Thanks a lot!

“For modern functionality, I need more than OpenGL 1.1. How do I determine what version and extensions are supported by a graphics card?”

Like Deguy already pointed out:

Under windows you have to use the extension mechanism to access the higher OpenGL functions.

Its a bit awkward but only MS could change that unfortunatly it doesnt look like it will ever gonna happen.
