AE+VS开发颜色符号系统之唯一值符号（二）

在主窗体中创建菜单

windows窗体中创建唯一值符号化菜单

添加唯一值符号化类（ArcGISClass)

新建UniqueValuesSymbol类  类型是Base Command

 

在类中的public override void OnClick()函数添加启动符号化窗口代码

完整代码如下：

using System;
using System.Drawing;
using System.Runtime.InteropServices;
using ESRI.ArcGIS.ADF.BaseClasses;
using ESRI.ArcGIS.ADF.CATIDs;
using ESRI.ArcGIS.Controls;
