此代码我想实现鹰眼导航（即在此代码中，
mapcontrol控件（ax
MapControl1）中显示的是主地图，而左下角的
mapcontrol控件（ax
MapControl2）进行鹰眼导航，ax
MapControl1中的视野范围在ax
MapControl2中用深蓝色边框进行框起来。无论是主视图
大小缩放还是通过鼠标移动视角，在ax
MapControl2都要跟着框起来，他固定
不动但是蓝色边框跟着移动）注意我的vs版本为2010，给出完整的修改代码，要细致的修改操作教程
本文解决了使用overview关联mapview中的地图时遇到的问题，包括mapview无法随窗口调整大小及刷新问题。通过让overview和mapview关联不同的地图来解决。
