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;
}
