Has anyone had this problem - I am using nehe''s setup code in my framework and the program works fine windowed but as soon as I run in fullscreen it crashes my machine. I am personally suspicious of borland which I am using to compile. Any ideas on how I can debug this? Cheers, DeVore

It is much more likely to be your video card or its drivers fault. What video card do you have, and do you have the newest drivers?

What OS you using? I had a crash problem using full screen in OpenGL using Nehe setup code under WinNT 4.

This was just down to the OS though.

I have a GeForce 1, with the latest drivers. I am running windows 98 on an AMD Athelon 600 with plenty of memory etc..
I haven''t had any problems with other programs that use OGL.

Yes, running the demos on my home PC which is running Me and a TNT2 Ultra I have never had a problem with full screen.

Only when running under NT4.

Try to add some tracing to your code... find out where it exactly crashes...

Make sure every pointer / handle is valid before using it.
Also don''t forget to release any allocated handle/resource in your code.... Windows can become unstable if you don''t release them. (If it''s not already ! :D )

If it''s the exact nehe code it should work fine... so most likely it will be a driver problem in this case...

NeHe has released some reworked base code so I replaced my old stuff last night and it all worked. So, tonight I shall be going through the two carefully to find out what was the problem. I presume it is in the fullscreen initialisation code since that is the only difference.
Very odd...

Unfortunately, I have no clue why it doesn''t work on your system. I have a TNT2 with the latest drivers running Win2K and I''m also using Nehe''s code and it works great in fullscreen and in windowed mode.

Sorry I can''t help you out.

i have a viper2 and i use win2k. to fix it for me, i just kill the window 1st, THEN change the resolution back

life is unfair, take advantage of it.
