AGPS定位基本原理浅析，AGPS（Assisted GPS，A-GPS，网络辅助GPS）定位技术结合了GPS定位和蜂窝基站定位的优势，借助蜂窝网络的数据传输功能，可以达到很高的定位精度和很快的定位速度，在移动设备尤其是手机中被越来越广泛的使用。(AGPS positioning the basic principles of analysis, AGPS (Assisted GPS, A-GPS, network-assisted GPS) positioning technology combines GPS positioning and cellular base station location advantage, with data transmission function of the cellular network, can achieve high positioning accuracy and very fast positioning speed, especially in the mobile phone devices are more widely used.)

这个是关于网络工作室的源代码,主要是用于网络编程的初级参考,希望能给刚入网络编程的朋友提供帮助(This is a studio on the network)

用vc实现邮件传输功能，主要采用winsock实现传输过程。有利于熟悉网络编程。(achieved using vc mail functionality, mainly winsock achieve transfer process. Help familiar with network programming.)

参考网上的资料写的gif编解码。 编码用gdi解析常用图片格式，然后组装成gif 解码吧gif的每一帧转换成dib gif文件格式网上有很多介绍 gif用的变长lzw压缩算法： 没弄懂原理，只知道过程。压缩取一个字符作为后缀，看看字符串是否存在。存在，用对应的编码作为前缀继续取；不存在把字符串添加到字典，前缀添加到输出流，后缀作为前缀继续取。解压取一个编码看看字典中是否存在。存在用对应的字符串的第一个字符作为后缀，看看当前字符串是否存在，不存在添加到字典中，后缀作为前缀，前缀对应的字符串添加到输出流，继续取；编码不存在，前缀对应的字符串的第一个字符作为后缀（这时当前字符串肯定不存在，字典中下一个可用编码肯定等于刚取出的编码），字符串添加到字典中，编码作为前缀，前缀对应的字符串添加到输出流，继续取。 编码流转换成字节流是按位从低到高的，window是小端模式（低字节在低地址），字节内低位在右边。 24位dib转换成8位dib时使用的八叉树算法 图片拉伸时参考的网上的双线性插值算法。 字典满了位数加一，位数是12时不加(Online reference materials written gif codec. Encoded using gdi resolve common image formats, and then assembled into a gif Each frame decode it into a gif dib There are many online gif file format introduced gif lzw with variable length compression algorithm: Did not understand the principle, only know the process. Compression takes a character as a suffix, and see if there is a string. Exist as a prefix to continue to take with the corresponding encoding there is no string to add to the dictionary, a prefix added to the output stream, the suffix as a prefix to continue to take. Take a look at extracting coding dictionary exists. Exist with the corresponding first character string as a suffix to see the current string exists, there is no add to the dictionary, the suffix as a prefix, the corresponding string to the output stream, continue to take coding does not exist, prefix corresponding first character string as a suffix (when the current string certainly does not exis)

说明：  ICO菜单，在VC下编译通过，比较漂亮和实用(ICO menu, compiled by the VC, more beautiful)
