Windows Mobile引路蜂map开发示例：第一个map应用

Windows Mobile引路蜂地图开发示例：第一个地图应用

打开Visual studio 创建一个新项目WM6GISEngineTutorial。把Form1改名为MainForm，添加对引路蜂类库的引用，并把guidebee.lic做为Content添加到项目中。

我们将使用MainForm来显示地图，下面的例子显示南京地图，缩放级别为13级，地图类型为Bing中国地图。

行45-49 设置Licence信息。
行51 从服务器更新地图类型配置，可选。
行52 将Windows Mobile平台上Gis.Drawing实现与开发包连接起来。
行53 设置工作线程数。
行54-59 创建地图实例，并启动工作线程。一般在程序结束时需调用_mapTileDownloadManager.Stop()停止工作线程。
行60-62 设置回调函数，其实第一个例子60，61行不是必须的。
行63-64 设置地图中心，地图类型和缩放级别。
行67-72 显示地图，当一个地图图片完成下载时，会通过回调函数 Done() 通知应用，一般在此更新地图。
行143-166 支持地图平移。

后面的例子设置地图类型，地址编码，路径查询等将在这个例子基础上改动，通过菜单来解释各项功能。
