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.

本文讲述的利用通讯控件发送与接收通讯数据都是基于二进制来实现的,基于文本的情况基本与此类似。要想利用好通讯控件还有其他一些应该注意的地方,比如波特率的设置、接收与发送缓冲区的设置以及通讯过程中的延时问题的处理等等。-This paper describes the use of communications controls send and receive communications are based on the binary data to achieve, based on the basic text of this and similar. To make good use of communication controls should also pay attention to some other place, such as baud rate settings, receiving and sending the buffer settings and communication latency in the process of dealing with such problems.
