请教高手指教Mo鹰眼问题

请大家多多指教了！！谢谢！！！<img src="images/post/smile/dvbbs/em09.gif" /><img src="images/post/smile/dvbbs/em09.gif" />

<P>我在对话框中实现的鹰眼 以下是指示图控制地图</P><P>void CDlgyy::OnMouseDownMap2(short Button, short Shift, long X, long Y)
{
 // TOD Add your control notification handler code here
 //画方框改变Map1窗口
    CMoRectangle r(m_map2.TrackRectangle());
 if(LPDISPATCH(r))
    pYYView->m_map1.SetExtent(r);
 //点击改变Map1位置
 CMoPoint pt(m_map2.ToMapPoint((float) X,(float) Y));
 if(LPDISPATCH(pt))
 pYYView->m_map1.CenterAt((pt.GetX() + r.GetWidth()/2),(pt.GetY() - r.GetHeight()/2));</P><P>}</P>

<P>当学会了绘制矩形框 rectangle </P><P>知道需要在地图控件的 beforelayerdraw   和 aferlayerdraw  和 beforetracklayerdraw  以及 afertracklayerdraw 事件中写代码就能OK</P>
