说明：  基于多线程实现点对点聊天工具。能传送文件，能处理字体，能实现动画功能。实现点对点的数据通信，实时的信息显示；能够传输文件；基于GDI实现曲线的动画效果，还有字体变化效果
(Based on multi-threaded peer-to-peer chat tool. Transmit files, can handle the fonts to achieve animation capabilities. To achieve the number of point-to-point According to the communications, real-time information be able to transfer files GDI-based animation curves, as well as the font change effect.)
