C + + get screen size

Api:

To get the screen size, you can use the following functions:

# include <windows.h>
int  CX   =  getsystemmetrics (sm_cxfullscreen); int  Cy   =  getsystemmetrics (sm_cyfullscreen);

The top two functions get the size of the display screen, but do not include areas such as the taskbar.

int  CX   =   getsystemmetrics (   sm_cxscreen   );    int  Cy   =   getsystemmetrics (   sm_cyscreen   );

These two functions get the actual size of the screen.
Mfc:

HDC hdc =  :: GetDC (HWND (NULL));               // Get the screen  DC int x  =  :: GetDeviceCaps (hdc,horzres);       // wide   int y  =  :: GetDeviceCaps (hdc,vertres);        // High    :: ReleaseDC (HWND (NULL), HDC);                  // Release DC
