帮忙，AO问题 ！

我在AO开发时，想让MapControl和PageLayoutControl1同步显示，比如在MapControl中放大地图后，切换到PageLayoutControl1中也同样显示放大后的地图，其实和ArcMap地图视图与版面视图切换功能一样，谁知道改怎么做？谢谢 ！<img src="images/post/smile/dvbbs/em02.gif" />

<P>这个早在论坛就讨论过多次了</P>
<P>vb代码如下</P><PRE>Public Sub CopyAndOverwriteMap()
    
  'Get IObjectCopy interface
  Dim pObjectCopy As IObjectCopy
  Set pObjectCopy = New ObjectCopy

  'Get IUnknown interface (map to copy)

  Set pToCopyMap = PageLayoutControl1.ActiveView.FocusMap

  'Get IUnknown interface (copied map)
  Dim pCopiedMap As IUnknown
  Set pCopiedMap = pObjectCopy.Copy(pToCopyMap)

  'Get IUnknown interface (map to overwrite)
  Dim pToOverwriteMap As IUnknown
  Set pToOverwriteMap = MapControl1.Map
  
  'Overwrite the MapControl's map
  pObjectCopy.Overwrite pCopiedMap, pToOverwriteMap
