Hi, Do you guys know how I can go about using opengl to render to a bitmap instead of a window. Ideally I don't want to open a window at all. Thanks

there's this, but you could always copy the color buffer to a buffer of COLORREFs using glReadPixels and the GL_BGR_EXT argument. After that look up saving bitmaps in MSDN and your home.
