Set the Windows 8.1 screen to rotate your code yourself, auto-rotate function code

Program code implementation enable or disable the Windows 8.1 tablet's own active rotation feature

Method One: Use the Setdisplayautorotationpreferences function function

#include <windows.h>/*typedef enum orientation_preference {   Orientation_preference_none              = 0x0,   Orientation_preference_landscape         = 0x1,   orientation_preference_portrait          = 0x2,   orientation_ preference_landscape_flipped = 0x4,   orientation_preference_portrait_flipped  = 0x8}orientation_preference; */typedef BOOL (WINAPI *psdarp) (orientation_preference ORIENTATION);p sdarp parp;int Main (int argc, char* argv[]) {PARP = ( Psdarp) GetProcAddress (GetModuleHandle (TEXT ("user32.dll")),  "Setdisplayautorotationpreferences"), if (PARP) { if (Atoi (argv[1]) = = 0) {PARP (orientation_preference) (Orientation_preference_landscape | orientation_preference_landscape_flipped));} if (Atoi (argv[1]) = = 1) {PARP ((orientation_preference) (Orientation_preference_none));}} else{printf ("System not supported.\t"); return 1;} return 0;}

Method Two: Set by the Write register to enable.
