测试传感器温度的控件...实在没什么可多介绍的了.VC-test temperature sensor controls ... nothing can introduce more of it. VC

DOS下，异步串口通信C代码，根据具体需要可裁减-DOS, asynchronous serial communication C code, according to the specific needs can be trimmed

基于消息的Windows串口通讯例子- Based on news Windows string mouth communication example

一个串口通信的例子-a serial communication example

一个基于串口通信的汽车行驶记录仪数据采集处理系统，这里是主程序和数据库，整个项目使用Delphi的Com+组件技术开发，后面将陆续上传各个组件的源码-a serial communication based on the vehicles running Recorder Data Acquisition and Processing System, which is the main program and database, the entire project using Delphi Com component technology development, will continue to upload behind all of the source components

本程序是针对特定GPS接收机--JAVAD公司的legacy的一个应用，用来收取标准的NMEA-1083GGA信息或JPS格式（JAVAD公司的特有GPS信息格式）的{RT，PO}信息，并统计数据大小与经历时间。本程序用VC6.0+串口控件MSComm实现，其中关于如何在数据长度不定的情况下实现数据帧的同步的方法可以借鉴到其它串口数据采集的应用之中，具备一定的实用价值-this program is targeted at specific GPS receiver-- JAVAD the legacy of an application, used to collect standard NMEA- 1083GGA information or JPS format (JAVAD company"s unique GPS information format) (RT, PO) information and statistical data on the size and duration. The procedures used VC6.0 Serial MSComm control, on how volatile the data length of the data frame synchronization method can draw on to other serial data acquisition applications, to have some practical value

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.
