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.
