昨天写了一版，通过搜索引擎来找公司的名称，好多前辈提出来这个的方式有些偏，于是就使用工商码来实现了一个，两个东西放在一起。先上界面
右边的输入框是填从哪个工商码开始找的，因为好多年前的公司我们肯定是不需要的了，再加上，编码的前八位是地区码，所以，我写了两个，一个是在市区的公司，一个是江宁的，找出一公司分别是两家公司之后在同一地区注册的。结束条件是，一连两条数据没有找到结果，当然，这其中还有校验码的问题，就是大家看见的代码中要除以10再从1加到9的效果。
效果很好，打算一直让它跑着，等数据跑出来了，文件另存为.xls文件 ，可以直接 用excel打开，这两个地区找完了，再去找其它地区的。
好了，上代码 ，其实代码很简单：
