Texture mapping simply doesn't work!

Hello, I tried to perform texture mapping in an openGL program, been doing what the tutorials said, and even copying from examples. But yet, it simply doesn''t work! I get, instead of a textured polygon, a polygon colored in its former color. Now, I think it has something to do with, maybe, one of these: 1. when I call glGetTextures, it doesn''t provide me back with any new ID! why is that? 2. I might not be doing something I should have been doing before trying to define the texture - change of some variables? some registers? defining a valid viewport before, or something? I simply don''t have a clue. If someone ran into a similiar problem, or knows why this happens, please give me a hand here. Thanks in Advance, Amir

Thank you all very much!

The thing is, al openGL commands must come after a wglMakeCurrent() call with the proper rendering context. It is never explicitly announced in the red book, as much as I can tell..

Thanks in Advance,Amir

When something doesn''t work and you are desperate, check some Nehe sources and try them on your computer to see if the problem comes from the gfx card, the computer or you
