Hi, I''m getting back to openGL, it''s been a few years. And when I got to programming I realized that I wasn''t sure what controled the screen resolution. I have a devmode structure to handle my fullscreen that I have to put window size in ( I think? ). I have a glViewport call setup like this glViewport( 0, 0, width, height ). and I create my window with GetSystemMetrics( SM_CXSCREEN ) and GetSystemMetrics( SM_CYSCREEN ). Now which of these is the actual resolution of my game? All that is necessary for the triumph of evil is that good men do nothing. -Edmund Burke

glViewport( 0, 0, width, height )

Width and Height.

I beleive the resolution of the screen is returned from SM_CXSCREEN = width, SM_CYSCREEN = height (returned with the GetSystemMetrics call).

The glViewport specifies the size of the OpenGL area in the window. It''s not the resolution...

hey Chris, yeah I''m not stupid. I know what resolution means, that wasn''t my question. Thanks anyway though.
