I found a demo source and exe file demonstrating how to access mode 13h. It doesn''t work (the source) with my compiler: Microsoft Visual C ++ 6 Introductory Edition. Can someone please give me a link or a tutorial showing how this can be done with my compiler? Thanks a lot,
Unfortunately, you''ll have to use DirectX if you want to change the video mode. With a Windows app, you can''t directly access the VGA hardware to switch to mode 13h. If you want to do graphics programming, I would recommend Allegro.
In windows, the GDI prevents access to the graphics card. You could disable the GDI (don''t worry too much about this one), use a dos compiler, such as djgpp, use DirectX like Martee said, or you could use the ChangeDisplaySettings function.
