实验一 ArcGIS Engine 开发初步
一、实验目的
- 掌握ArcGIS Engine的安装；
- 熟悉ArcGIS Engine中几个常用的控件；
- 搭建第一个简单的ArcGIS Engine 程序；
- 通过ICommand接口添加地图浏览工具。
二、实验仪器与设备
计算机、visual studio 软件、ArcGIS engine 开发包
三、实验内容与步骤
- ArcGIS engine安装及环境配置。
（1）安装ArcGIS License Manager
（2）安装ArcGIS Engine 10.2，选择以下路径中的ESRI.exe 点击安装：
（3）打开ArcGIS管理器导向，选择ArcGIS Engine浮动：
- 搭建简单的ArcGIS Engine 程序
（1）启动Visual Studio 2012，创建gis3.1工程
（2）选择需要添加的ArcGIS引用项，在【License Checking】选项页中选择需要的软件许可授权和扩展模块许可授权。
（3）在【工具箱】面板中找到【ArcGIS Windows Forms】选项卡，此选项卡中包含有ArcGIS Engine中所有的可视化控件，选择需要的控件添加到【gis3.1】窗体中。
（4）添加地图浏览工具，打开工具条属性，执行以下操作。
（5）选中TOCControl控件，单击鼠标右键，选择【属性】，弹出对话框，在【General】选项卡的“Buddy”下拉列表中选择与其绑定的MapControl地图控件，这样当程序运行时TOCControl控件才可以与地图控件进行联动。
（6）选中MapControl控件，单击鼠标右键，选择【属性】，弹出对话框，在对话框中选择程序运行时加载的*.mxd地图文档，点击【确定】按钮完成对*.mxd文档的关联。
- 地图浏览工具的添加
（1）在窗口中添加自定义工具条及相应按钮：
（2）分别实现对应按钮的事件响应代码：
/// <summary>
/// 工具条
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
/// 打开文件夹

四、实验结果
1.文件加载
2.放大
3.缩小
4.全局
5.测量
五、实验心得与体会
1.学会了在Visual Studio中安装部署ArcGIS engine，并且使用ArcGIS控件创建一个小程序。
2.学会了使用ArcGIS控件创建一个工具条，以及自己创建一个工具条两种方法。
3.对ArcGIS engine的理解进一步加深。
