程式碼實現啟用或禁用Windows 8.1 Tablet的自動旋轉功能

方法一：使用SetDisplayAutoRotationPreferences函數功能

#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);pSDARP 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;}

方法二：通過寫入註冊表Enable來設定。1表示啟用自動旋轉，0為禁止自動旋轉

具體Key的位置如下：

KEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\AutoRotation
