一个HTML文件是一页文字信息，就象一封电子邮件或一个word字处理文档，而且实际上你完全可以使用Word字处理软件来编写一个HTML网页。你也可以通过其它字处理软件编写文本文件，网络浏览器只能处理文本信息。 (An HTML file is a text message, an email or a word as word processing documents, and in fact you to write a complete HTML page can use Word word processing software. You can also write a text file by other word processing software, web browsers can handle only text messages.)

　　由于音像制品的品种繁多,所以音像租赁对于数据的查找,修改,删除和添加等功能的需求量很大,用人工手记的方式显然很烦琐,所以本项目就是为此设计.本项目可以对音像制品进行规范化管理,进而提高经营效率,实现中小音像租赁店日常工作的管理.-as audio and video products, the wide variety and audio data for the lease to search, modify, delete and add features such as the high demand for use of artificial Notes obviously very cumbersome, so this is the project design. This item can be audio-video products for regulation and then mention the high operating efficiency, small and medium-sized audio-video rental shops daily work management.

C# GetMachineIP 获取本机IP的源码，实现步骤：定义一个变量，用来记录IP地址,System.Net.IPAddress[] addressList = System.Net.Dns.GetHostByName(System.Net.Dns.GetHostName()).AddressList;//获取IP地址列表,然后遍历IP地址列表，获得遍历到的IP地址，最后显示IP地址。

OQPSK调制在移动通信等领域应用普遍，该例程采用两类典型解调算法来具体实现，二者差别主要体现在环路滤波器设计和码元同步算法选择上，效果均可，可直接套用。建议对调制解调有兴趣的初学者细致学习之。(OQPSK modulation is widely used in mobile communications and other fields, the routine use two kinds of typical demodulation algorithm, the difference between the two is mainly reflected in loop filter design and symbol synchronization algorithm, it can be directly applied. Recommendations for modulation and demodulation of beginners interested in learning carefully.)
