1、实验报告GIS应用软件开发专 业： 测绘工程 班 级： 10级测绘三班姓 名： 学 号： 指导教师： 胡 亚 撰写时间：2013年5月20日星期一目录一、程序运行演示2二、问题及解决方案6三、源程序代码7四、心得体会14一、程序运行演示1. 新建项目文件，并实现file中的基本功能，显示地图基本要素。如图1图12. 在工具栏加载按钮，按钮功能是对当前视图缩小3倍；在工具栏加载工具，工具功能在地图上标注当前日期。如图2图2按钮实现缩小3倍功能操作，如图3图33. 点击地图节点，弹出如图4，图5菜单并实现菜单中的内容：图4图54. 点击图层节点，弹出如图6菜单并需要实现菜单中的内容图65. 点击L
2、egend Class，弹出符号选择对话框，该对话框供用户按需要选择符号并进行更改。如图7图76. 打开图层属性表，用户选择某条记录，可弹出如图8,9所示的右键菜单，并实现右键菜单中的内容图8图9二、问题及解决方案问题1.VS2008与2010之间要进行格式转换，按照所导向的步骤进行，否则程序将无法正常运行，出现错误问题2.构建好基本框架后，地图文档中要素显示出现问题。此问题要添加licence控件，否则无法显示地图要素。问题3.使用Toolbar和Toc功能时无法进行操作此问题应在属性设置时建立关联功能。问题4.程序Program文件中要添加相应功能键语句，否则将无法实现功能。问题5.引用接
3、口，方法，例如ADF，要添加相应的引用，否则程序出现错误。问题6. 在实现两个自定义按钮与工具时，遇到的问题：先直接引用现有项未实现，发现缺少一些东西，后自己直接创建的Basetool和Basecommand类；在代码中报错，重新生成解决方案后顺利解决这个问题。问题7. 在实现地图和图层节点的右键功能时，遇到琐碎的问题，在这个过程中直接引用老师所给的几个类，但是报错，是因为命名空间未做修改；缺少引用，需要根据错误提示添加相应的引用三、源程序代码using System;using System.Collections.Generic;using System.ComponentModel;us
