keybd_event，mouse_event 模拟产生键盘事件、鼠标事件的使用

模拟鼠标产生鼠标事件、键盘事件有时候非常有用，比如在自动化测试中。源程序在：http://download.csdn.net/detail/dijkstar/4035890

关键程序：

比如一个应用：自动关闭弹出的Messagox对话框（http://blog.csdn.net/dijkstar/article/details/8761481）（2013-04-05编辑）

void CSimulateMouseView::OnLdbclick() 
{
	//将鼠标的位置放在窗口的标题条上
	POINT lpPoint;
	CRect rc;
	CWnd* pParent = AfxGetApp()->GetMainWnd();
	pParent->GetWindowRect(&rc);
	lpPoint.x = rc.left+50;
	lpPoint.y = rc.top+10;
	SetCursorPos(lpPoint.x, lpPoint.y);

	//双击该标题条
	mouse_event(MOUSEEVENTF_LEFTDOWN,0,0,0,0);
	mouse_event(MOUSEEVENTF_LEFTUP,0,0,0,0);
	mouse_event(MOUSEEVENTF_LEFTDOWN,0,0,0,0);
	mouse_event(MOUSEEVENTF_LEFTUP,0,0,0,0);
}

void CSimulateMouseView::OnLclick() 
{
	//将鼠标的位置放在窗口的关闭按钮上
	POINT lpPoint;
	CRect rc;
	CWnd* pParent = AfxGetApp()->GetMainWnd();
	pParent->GetWindowRect(&rc);
	lpPoint.x = rc.right-5;
	lpPoint.y = rc.top +5;
	SetCursorPos(lpPoint.x, lpPoint.y);

	//单击
	mouse_event(MOUSEEVENTF_LEFTDOWN |MOUSEEVENTF_ABSOLUTE,0,0,0,0);
	mouse_event(MOUSEEVENTF_LEFTUP|MOUSEEVENTF_ABSOLUTE,0,0,0,0);
}


BOOL CSimulateMouseView::PreTranslateMessage(MSG* pMsg) 
{
	// TODO: Add your specialized code here and/or call the base class
	if (pMsg->message==WM_KEYDOWN && pMsg->wParam==0x41)
	{
		::MessageBox(NULL, "A 键按下", "提示", MB_ICONQUESTION);
		return FALSE;    //不翻译消息，直接将消息传递下去。具体可查MSDN。
	}
	if (pMsg->message==WM_KEYUP && pMsg->wParam==0x41)
	{
		::MessageBox(NULL, "A 键提起", "提示", MB_ICONQUESTION);
		return FALSE;    //不翻译消息，直接将消息传递下去。具体可查MSDN。
	}


	return CFormView::PreTranslateMessage(pMsg);
}

//模拟键盘事件
void CSimulateMouseView::OnLclick2() 
{
	//【A】键按下
	keybd_event(0x41, 0, 0, 0); 

	//【A】键抬起
	keybd_event(0x41, 0, KEYEVENTF_KEYUP, 0);
}
