终于搞得像个样子了.
? 实现功能:
? ?功能1:加载、保存地图文档
? ?功能2:鹰眼
? ?功能3:添加、删除、移动图层
? ?功能4:专题图
? ?功能5:属性表查看
? ?功能6:地图输出
? ?功能7:设置图层符号
? ?功能8:状态栏信息的添加和实现
?开发环境:
?Vs2012+arcgisEngine10.2
?
?演示效果:
? ? ?
?
?

?其中在地图导出的代码,这部分搞了很久:

?在以上代码中，比较关键的两句:
?m_hookHelper = new HookHelperClass();
?m_hookHelper.Hook = this.axMapControl1.Object;
?
?之前在测试的时候，出现"未将对象引用设置到对象的实例"的问题，最后用设置断点的方法，发现了这个错误，解决了.

?总结:
?本次的课程设计终于可以结束了，也学到很多.
