I am writting a program and was wondering if there was an easy way to test which resolution the display was currently in. (i.e. 1024 x 768 or 800 x 600). I was aslo wondering if there was a way change the resolution of the display, from within the program running on the dos window ...
GetDeviceCaps( ) is what you're looking for.
int nWidth = GetDeviceCaps( hDC, HORZRES );
int nHeight = GetDeviceCaps( hDC, VERTRES );
As for changing the display, I'm not sure. You can easily do it using DirectX or OpenGL but not sure about straight Win32.
I seem to get an error even after i include headers
error C2065: 'hDC' : undeclared identifier
Any Idea why?
just means that you are using a var 'hDC' that isn't referenced and declared. make sure spelling is correct.
Somehow I knew that would happen. I should've been more clear. hDC is a variable you create that is a handle to the device context. Look up GetDC ... make sure you ReleaseDC also.
GetSystemMetrics
I went with MrWizzard's help and it works great .
Thank you.
