View Full Version : ChangeDisplaySettings

02-24-2001, 12:18 PM
What difference does it make if I pass 0 for the flags to ChangeDisplaySettings or if I pass CDS_FULLSCREEN? They seem kinda the same to me, and the help file doesn't help on that at all. Which is best for games?

Oh yeah, where can I get the official OpenGL programming guide/reference manual? All I have is a badly organized help file that came with VC++.

Thanks for the help!

You should look in the .chm for GDI from the Platform SDK:
0 - The graphics mode for the current screen will be changed dynamically.

CDS_FULLSCREEN - The mode is temporary in nature.
Windows NT/2000: If you change to and from another desktop, this mode will not be reset

What that means... http://www.opengl.org/discussion_boards/ubb/smile.gif
If your program crashes and you have changed the resolution with CDS_FULLSCREEN does it seems like it will be restored.
