8051点亮LED程序

聊天室，可以用来聊天的聊天室,差不多像QQ一样的东西(chatroomthat you can use it tochat with your friends，just like qq)

自己写的一个将飞信xml聊天记录专程txt文档的小程序，其实就是对xml文档的解析，有同志感兴趣扩展一下看能不能和QQ互动。(Himself wrote a letter to fly a special trip xml chat applet txt document, in fact, is the xml document analysis, there are comrades interested in you and see if I can expand and QQ interaction.)

一款webQQ登陆的小程序，可以登陆并发表文字说说，图文混合说说，设置说说可见权限。涉及WinHttp知识，spidermonkey脚本引擎知识(WebQQ landed a small program, you can log in and post text talk, text and graphics to talk about, talk about the visible set permissions. Involving WinHttp knowledge, spidermonkey scripting engine knowledge.)

能够简单进行一些计算，比如，1，，，，，+100可以很快计算出来，十分方便。实用性很强。占用内存比较小，运行速率快，效率高，深受广大程序员喜爱，移植性好。

国际电气工程先进技术译丛 电力变流器电路 本书揭示了整流、逆变、周波变流和变流电路的所有关键组分——描述其通断，电压和电流的关系，还有变流器的性质、运行、控制和性能及其实际应用。书中的许多方法基于经典数学，同时包含了大量有解的数字例题。本书主要介绍了单相和三相AC-DC整流器电路，功率因数和谐波性能，不同的DC-AC逆变器电路，PWM调制器和相位可控矩阵AC-AC周波变流器电路，降压、升压和降升压DC-DC变流器电路，以及用于DC-DC电路的开关模式变流器电源(International Electrical Engineering advanced technology on power converter circuit This book reveals all the key components of the rectifier, inverter, Zhou Bo converter and converter circuit, which describes the relationship between the current and voltage, current and voltage, as well as the nature, operation, control and performance of the converter and its application. Many methods in the book based on classical mathematics, also contains a large number of digital solutions for example. This book mainly introduces the single-phase and three-phase AC-DC rectifier circuit, power factor and harmonic performance, different DC-AC inverter circuit, PWM modulator and phase controllable matrix AC-AC frequency converter circuit, buck, boost and drop boost DC-DC converter circuit, and for the DC-DC circuit switch mode converter power supply)

一个C#的导航条，非常漂亮，希望大家喜欢，个人感觉还可以-using c#
