C++模拟键盘鼠标消息

#include <Windows.h>
/* 
 * ===  FUNCTION  ======================================================================
 *         Name:  LeftClick
 *  Description:  左键按下消息
 * =====================================================================================
 */
void LeftClick ( )
{  
  INPUT    Input={0};
  // left down 
  Input.type      = INPUT_MOUSE;
  Input.mi.dwFlags  = MOUSEEVENTF_LEFTDOWN;
  ::SendInput(1,&Input,sizeof(INPUT));

  // left up
  ::ZeroMemory(&Input,sizeof(INPUT));
  Input.type      = INPUT_MOUSE;
  Input.mi.dwFlags  = MOUSEEVENTF_LEFTUP;
  ::SendInput(1,&Input,sizeof(INPUT));
}
/* 
 * ===  FUNCTION  ======================================================================
 *         Name:  RightClick
 *  Description:  右键按下消息
 * =====================================================================================
 */
void RightClick ( )
{  
  INPUT    Input={0};
  // right down 
  Input.type      = INPUT_MOUSE;
  Input.mi.dwFlags  = MOUSEEVENTF_RIGHTDOWN;
  ::SendInput(1,&Input,sizeof(INPUT));

  // right up
  ::ZeroMemory(&Input,sizeof(INPUT));
  Input.type      = INPUT_MOUSE;
  Input.mi.dwFlags  = MOUSEEVENTF_RIGHTUP;
  ::SendInput(1,&Input,sizeof(INPUT));
}

/* 
 * ===  FUNCTION  ======================================================================
 *         Name:  鼠标移动消息
 *  Description:

 */
void MouseMove (int x, int y )
{  
        double fScreenWidth    = ::GetSystemMetrics( SM_CXSCREEN )-1; 
        double fScreenHeight  = ::GetSystemMetrics( SM_CYSCREEN )-1; 
        double fx = x*(65535.0f/fScreenWidth);
        double fy = y*(65535.0f/fScreenHeight);
        INPUT  Input={0};
        Input.type      = INPUT_MOUSE;
        Input.mi.dwFlags  = MOUSEEVENTF_MOVE|MOUSEEVENTF_ABSOLUTE;
        Input.mi.dx = fx;
        Input.mi.dy = fy;
        ::SendInput(1,&Input,sizeof(INPUT));
}
int main(){

        while(true)
        {
                MouseMove(0,100);

                Sleep(5000);

                MouseMove(200,0);

                Sleep(5000);
        
        }
    //RightClick ( );
    //LeftClick ( );
        return 0;
}

　　以上是使用sendinput函数

以下是使用keybd_event函数

//#include <Windows.h>
#include <afxwin.h>

int main()
{

        //CWnd *pWnd = CWnd::FromHandle(FindWindow("ConsolWindowClass", NULL));   GetConsoleWindow(void);
        CWnd *pWnd = CWnd::FromHandle(GetConsoleWindow());   //本控制台程序发送按键消息
        if (pWnd->GetSafeHwnd()) 
                { 
                        pWnd->ShowWindow(SW_NORMAL); 
                        pWnd->SetForegroundWindow(); 
                        //keybd_event(VK_CONTROL, 0, 0 ,0);
                        keybd_event('E', 0, 0 ,0);
                        keybd_event('E', 0, KEYEVENTF_KEYUP ,0);

                        //keybd_event(VK_CONTROL, 0, KEYEVENTF_KEYUP,0);
                }
        return 0;
}
