串口通讯，能显示串口数据发送，接受，内带详细代码(Serial communication, serial data can be displayed to send, accept, with detailed code)

如何获取线程关联用户名和域名,不错,很好()

qt 开发的聊天源代码，使用 qtcpsocket 开发，容易看懂( qt source for tcp client)

上传下载源码，支持 断点续传，使用 libcurl(Upload and download the source code, support for HTTP, use libcurl)

文件拷贝猎手，能进行断点续传功能，方便局域网内部的共享文件拷贝！(File copy hunter, capable of HTTP functionality, easy to share the internal LAN file copy!)

通过客户端与服务器端文件对比，实现自动升级功能。(Through the client and server-side document comparison, automatic update feature.)

超宽带室内定位研究，本文主要研究基于超宽带的室内定位技术的研究，并且对室内定位技术的算法做了介绍。(UWB indoor positioning research, this paper research is based on UWB indoor positioning technology research, and the algorithm for indoor positioning technologies have been described.)

又一个使用ICMP.DLL实现ping的小例子 (Another example of using ICMP.DLL to implement ping)

一般地，把三角形的三个角A，B，C和它们的对边a，b，c叫做三角形的元素。已知三角形的几个元素求其他元素的过程叫做解三角形。解三角形，常用到正弦定理和余弦定理和面积公式等。正弦定理a/sinA=b/sinB=c/sinC=2R（2R在同一个三角形中是恒(The Triangle software, wrote)
