I can't seem to find any function which will allow me to obtain the Windows screen resolution and/or set it in C++.
I would like to be able to change it, then change it back.
Thanx

Thanx. Now I just have to figure out how to use it. I will, eventually.

To get the screen resolution, you can use the function GetWindowRect(). I've written an article in my blog.

I'm also trying to do the same thing and i'm running on windows xp. i kind of understand the links you gave RFBourquin except i'm pretty new to C++, only using it in a class for the past 6 weeks. I'm having trouble understanding how to use the commands from http://msdn.microsoft.com/en-us/library/dd183413.aspx. i was hoping someone could give an example of using the commands from that page and change the resolution to 800 x 600 as an example please. thank you.

(First, declare the device mode class)
DEVMODE NewDevice;
(The members of this class you will need)
NewDevice.dmSize = sizeof(DEVMODE);
NewDevice.dmPelsWidth = 1024;
NewDevice.dmPelsHeight = 768;
(In the main program)
ChangeDisplaySettings(&NewDevice, 0);

You may want to have a look at WMI (windows management instrumentation). It provides an extensive API for accessing your systems information.
