    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.

    MSComm控件资料,Visual Basic 6.0(以下简称VB) 是一种功能强大、简单易学的程序设计语言。它不但保留了原先Basic语言的全部功能,而且还增加了面向对象程序设计功能。它不仅可以方便快捷地编制适用于数据处理、多媒体等方面的程序,而且利用ActiveX控件MSComm还能十分方便地开发出使用计算机串口的计算机通信程序。本文结合计算机通信的两个例子,详细介绍如何在VB中使用MSComm控件。 处理方式 -MSComm information, Visual Basic 6.0 (VB hereinafter) is a powerful, relatively simple programming language. It not only retains the original Basic language functionality, but also an increase of object-oriented programming design functions. It will not only facilitate the efficient preparation of the application to data processing, multimedia and other aspects of the procedure, and the use of MSComm ActiveX control can be very convenient to use the computer to develop the computer serial port Communication Program. Based on computer communication, the two examples in detail how to use VB MSComm. Approach

    自己使用VB编写的串口通信程序,1号和2号。将两个COM口用串口线连接,就可以运行这两个程序了。实现的功能:1号程序随机发送两个数字,2号程序接收并进行计算,然后发回1号机,1号机接收并显示出来。-its own use VB prepared by the serial communication program, 1 and 2. The two COM ports with serial line connectivity, it can run on the two proceedings. The functions : 1 random procedure to send two figures, the No. 2 receiver and procedures for calculating and then sent back No. 1, No. 1 receiver and displayed.

  • 串口通信程序,通过汇编语言使用BIOS的。
    本串行通信程序利用汇编语言通过BIOS中断调用和DOS功能调用实现PC机双机串行通信。其中,上位机和下位机串行口均为辅串口COM2(口地址为2FXH),对外用9针连接器与令一台PC机连接;BIOS通过“INT 14H”4个中断服务子程序,分别完成串口初始化编程、发送一帧数据、接受一帧数据以及测试通信线状态。本程序分为PC机串口自动测试程序(目的是测试串口好坏)和PC机全双工双机通信程序两个部分。-the serial communications procedures through the use of assembly language BIOS interrupt calls and function calls DOS PC Dual Serial Communication. Among them, PC and the next crew will be supplemented by serial port Serial COM2 (I address 2FXH) external with 9-pin connectors and enable a PC connection; through the BIOS "INT 14H," four interrupt service routines, complete serial port initialization programming, Send a data receiving a data communications test and the state line. The procedures are divided into PC serial automatic test procedure (for the purpose of testing Serial good or bad) and full-duplex PC-machine communication program two parts.
