上传个考勤系统,希望别人也能用.该代码只能算初级的东东,软件代码复用性不高,重复代码比较多.唯一感觉有点取鉴的可能就是端口和dll的连接,还有线程的使用,本想改一改,但是手头没有考勤机了,对应考勤机是890C的.-From a performance appraisal system, I hope others can use. The code can only count the primary Dongdong, software, code reusability is not high, repeat the code more. The only feeling a little check Kam is probably dll ports and connections, There are threads to use, simply wanted to, but do not have attendance machine, and the corresponding attendance machine is the 890C.
