C#+ARCGISENGINE开发查找地图元素并高亮显示代码1(2008-12-13 13:02:12) 转载标签： 杂谈分类： 程序源代码 这是我帮同学做的一个简单的上机作业，本来是想做查找最短路径和查找地图元素(高亮显示)两个功能的，只是查找最短路径的代码没有填进去，如果哪位朋友需要的话，可以发邮件给我啊(wang_)下面是查找地图元素(高亮显示)的主要代码：/frmMain.cs/ Copyright 2006 ESRI/ All rights reserved under the copyright laws of the United States/ and applicable international laws, treaties, and conventions./ You may freely redistribute and use this sample code, with or/ without modification, provided you include the original copyright/ notice and use restrictions./ See use restrictions at /arcgis/developerkit/userestrictions.using System;using System.Drawing;using System.Collections;using System.ComponentModel;using System.Windows.Forms;using System.Data;using ESRI.ArcGIS.Carto;using ESRI.ArcGIS.Controls;using ESRI.ArcGIS.esriSystem;using ESRI.ArcGIS.SystemUI;using ESRI.ArcGIS.NetworkAnalyst;/ This is the main form of the space NAEngine/ / Summary description for Form1./ public class frmMain : System.Windows.Forms.Form/ / Required designer variable./ public IMapControl2 pMapControl;private System.ComponentModel.Container components = null;private System.Windows.Forms.Splitter splitter1; private System.Windows.Forms.ComboBox cmbLayers;/ Context menu objects for NAWindows context menuprivate System.Windows.Forms.ContextMenu contextMenu1;private System.Windows.Forms.MenuItem miLoadLocations;private System.Windows.Forms.MenuItem miClearLocations;/ ArcGIS Controls on the formprivate ESRI.ArcGIS.Controls.AxMapControl axMapControl1;private ESRI.ArcGIS.Controls.AxLicenseControl axLicenseControl1;private ESRI.ArcGIS.Controls.AxToolbarControl axToolbarControl1;private ESRI.ArcGIS.Controls.AxTOCControl axTOCControl1;/ Listen for context menu on NAWindowprivate IEngineNAWindowEventsEx_OnContextMenuEventHandler m_onContextMenu;/ Reference to Network Analyst Environmentprivate IEngineNetworkAnalystEnvironment m_naEnv;/ Reference to NAWindow.
