VB6diqu

说明：  今天给大家带来使用文本文件作为数据源的 ComboBox中国城市三级联动的代码。 1.地区库更新非常方便，不会影响到其他功能（区划代码是唯一的）。 2.文本文件读取来速度很快。(n the past, I used VB6 to write an example of three-level linkage of ComboBox in Chinese cities, using MDB database. A few years ago, the code, the regional database is not the latest. Today we bring you the code of ComboBox, which uses text files as data sources, for three-level linkage of Chinese cities. 1. The regionalization library updates are very convenient and will not affect other functions (regionalization code is the only one). 2. Text files are read very fast.)
