2、gend Class，彈出符號(hào)選擇對(duì)話框，該對(duì)話框供用戶(hù)按需要選擇符號(hào)并進(jìn)行更改。如圖7圖76. 打開(kāi)圖層屬性表，用戶(hù)選擇某條記錄，可彈出如圖8,9所示的右鍵菜單，并實(shí)現(xiàn)右鍵菜單中的內(nèi)容圖8圖9二、問(wèn)題及解決方案問(wèn)題1.VS2008與2010之間要進(jìn)行格式轉(zhuǎn)換，按照所導(dǎo)向的步驟進(jìn)行，否則程序?qū)o(wú)法正常運(yùn)行，出現(xiàn)錯(cuò)誤問(wèn)題2.構(gòu)建好基本框架后，地圖文檔中要素顯示出現(xiàn)問(wèn)題。此問(wèn)題要添加licence控件，否則無(wú)法顯示地圖要素。問(wèn)題3.使用Toolbar和Toc功能時(shí)無(wú)法進(jìn)行操作此問(wèn)題應(yīng)在屬性設(shè)置時(shí)建立關(guān)聯(lián)功能。問(wèn)題4.程序Program文件中要添加相應(yīng)功能鍵語(yǔ)句，否則將無(wú)法實(shí)現(xiàn)功能。問(wèn)題5.引用接口

3、，方法，例如ADF，要添加相應(yīng)的引用，否則程序出現(xiàn)錯(cuò)誤。問(wèn)題6. 在實(shí)現(xiàn)兩個(gè)自定義按鈕與工具時(shí)，遇到的問(wèn)題：先直接引用現(xiàn)有項(xiàng)未實(shí)現(xiàn)，發(fā)現(xiàn)缺少一些東西，后自己直接創(chuàng)建的Basetool和Basecommand類(lèi)；在代碼中報(bào)錯(cuò)，重新生成解決方案后順利解決這個(gè)問(wèn)題。問(wèn)題7. 在實(shí)現(xiàn)地圖和圖層節(jié)點(diǎn)的右鍵功能時(shí)，遇到瑣碎的問(wèn)題，在這個(gè)過(guò)程中直接引用老師所給的幾個(gè)類(lèi)，但是報(bào)錯(cuò)，是因?yàn)槊臻g未做修改；缺少引用，需要根據(jù)錯(cuò)誤提示添加相應(yīng)的引用三、源程序代碼using System;using System.Collections.Generic;using System.ComponentModel;usi
