说明： VC+Access编写的城市公交车查询系统，需要先配置数据源，这个小系统能够按车次、车站查询公交车，会列出查询路线所经过的停靠点，在VC6下顺利编译。 (The urban bus query system compiled by VC+Access needs to configure the data source first. This small system can query the bus according to the number of trains and stations. It lists the parking points of the query route and compiles smoothly under VC6.)
