专题图、设置图层符号等功能汇总

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.
