Hi, here is some problem : When i get Nehe''s tutors, there was problem in win98 with Riva TNT2! F.e. there was used 640x480x16 bit mode, in win98 the display won''t to resize to this resolution from higher in case if in Display->Settings->Advanced sets "Ask me before applying new color settings". In other cases it works fine! I just interesting, if my porgramm will run on many systems can it be possible to switch to this mode (640x480) even if in DisplaySettings sets "Ask me before ..." ???? ???

I used 5 lines of DirectDraw code for the mode switch, and that works pretty well. I don''t thrust that system level API for changing the screen resolution.
