用 Winsock 控件,使你的系统时间与格林尼汉标准时间同步,(Use the Winsock control to synchronize your system time with Greenwich mean time,)

VC根据DirectX的截图示例源码下载,你看懂了话都能截图了。要编译此程序需DirectX SDK5.0示例中的ddutil.h与ddutil.cpp文件,请自行参加工程，VC++编程学习源码，很好的参考资料。(VC according to the DirectX screenshot example source code download, you read the words can screenshot. To compile this program requires DirectX SDK5.0 example of ddutil.h and ddutil.cpp files, please participate in the project, learning VC++ programming source code, a good reference.)

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)

DXF轨迹图转G代码，有 直线，圆，圆弧，样条曲线，优化多段线，多段线。与下位机串口通讯！无法编译，是因为要先注册mscomm控件(DXF trajectories turn the G-code, line, circle, arc, spline curves to optimize the polyline, polyline. With lower serial communications! Not compile because the first registered mscomm controls)

说明：  基于CSocket的TCP多人聊天程序 平常自己练习用的！(CSocket of TCP-based chat program over usual practice their own use!)

说明：  包括两个类，能够进行类似属性表 属性页的编程，但功能更多(Includes two classes, a similar property to the table properties page programming, but more features)
