如何用程序单击程序外的座标, 怎么总是单击不成功(100分)

如何用程序单击程序外的座标, 怎么总是单击不成功<br><br>目前我已用FindWindow及ShowWindow激活了指定窗口，但SendMessage及PostMessage对他都无效，不能点击窗口的指定区域（比如文件菜单）<br><br><br>程序如下<br><br>var<br>&nbsp; t_WinHandle: THandle;<br>begin<br>&nbsp; t_WinHandle := FindWindow(nil, 'EditPlus');<br>&nbsp; ShowWindow(t_WinHandle, SW_SHOWMINIMIZED);<br>&nbsp; ShowWindow(t_WinHandle, SW_SHOWMAXIMIZED);<br>&nbsp; ShowWindow(t_WinHandle, SW_SHOWNORMAL);<br><br>&nbsp; SetCursorPos(200, 150);<br>// &nbsp;SendMessage(t_WinHandle, WM_LBUTTONDOWN, 0, 0);<br>&nbsp;PostMessage(t_WinHandle, WM_LBUTTONDOWN, 0, 0);<br><br>程序正好移到了文件菜单，就是不单击

setcursorpos( pt.x, pt.y ); &nbsp;<br>mouse_event( mouseeventf_leftdown, 0, 0, 0, 0 ); &nbsp;<br>mouse_event( mouseeventf_leftup, 0, 0, 0, 0 ); &nbsp;<br>mouse_event( mouseeventf_leftdown, 0, 0, 0, 0 ); &nbsp;<br>mouse_event( mouseeventf_leftup, 0, 0, 0, 0 ); &nbsp; <br>&nbsp;

谢谢
