键盘上的power键

Question

现在已经知道VK数值是0xFF，在程序中如何触发他 
keybd_event(0xFF,0,0,0); 
keybd_event(0xFF,0,KEYEVENTF_KEYUP,0);  
这样不行,现在就是要实现按下Power按下的效果，不要那个ExitWindowEx

Answer 1

// Simulate a key press
         keybd_event( 0xFF,
                      0x45,
                      KEYEVENTF_EXTENDEDKEY | 0,
                      0 );      // Simulate a key release
         keybd_event( 0xFF,
                      0x45,
                      KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP,
                      0);
