How can I ...?

I''m not sure about doing it using OpenGL commands but take a look into the EnumDisplayDevices and EnumDisplaySettings on MSDN. These are standard Windows functions which should work just fine.

If you switched to DirectX just for that, I''ve nothing to say to you.
(In old arabic countries, avoiding to speak to someone was the most insulting thing one could do.)

Neither OpenGL nor Direct3D have any functions for doing things specific to the windowing system. DirectX does: if you have DirectX 8.0, DirectGraphics includes a branch which will do this; otherwise, DirectDraw does it. OpenGL relies on the window system for that functionality since all it's a 3D API. To change the display mode, you use the Win32 API function ChangeDisplaySettings.
I'm getting sick of people comparing OpenGL to DirectX. OpenGL is a 3D API. DirectX is a set of APIs including DirectDraw, Direct3D, DirectSound, DirectInput, and DirectPlay.
OpenGL == Direct3D
OpenGL + GLU == DirectGraphics || Direct3D + DirectDraw
SDL == DirectX
See the breakdown?
Elixir, if you switched just because you lacked the intellectual capacity to figure this out, then I do have something to say to you: you're an idiot. I mean, there are tons of OpenGL tutorials that cover this!

Wrong. You have to use standard Windows functions to do that, eg. EnumDisplayDevices and EnumDisplaySettings, this works fine.
OpenGL is a 3D API, not a window management system.
>This is one of the main reasons I switched to DirectX (Please don''t flame me!).
This is the most stupid thing I ever heard of an excuse. What are you doing in the forum then ? Go to the DirectX forum and be happy that you can enumerate display modes, this seems to be the only thing D3D can do right.

Very thank you to all.
My question is different-thing...
Ex) 640x480x16 <- If this mode is OpenGL hardware accelatable,
1600x1024x32 <- If this card is not supportable OpenGL hardware accelation...
How can I find these modes?

eg it takes way more memory to store the info for a 1600x1200x32 window than it does 1024x768x16. more than 4x as much memory in this case in fact.
>>As I know, OpenGL is not support all graphic modes.
How can I get OpenGL supportable graphic modes<<
ok i understand this now, opengl does support all resolutions+colour depths any that aint supported eg 32bit colour on a voodoo3 are due to the card not being able to do them and not opengl.
ie if directx can support a certain resolution/colour depth then opengl can support the same
