Description: 积分分离PID算法的思想是：当被控量与设计的偏差量偏差较大时，取消积分量，以免积分量使系统稳定性降低，超调量增大；当被控值接近定值时，引入积分控制，以消除静差，提高系统精度。-integral separation PID algorithm thinking is this : When the volume charged with the design of larger deviations deviation, the abolition of Integral volume, the volume so integral to reduce the system stability, over-regulation increased; When charged with setting value approach, the introduction of integral control to eliminate static error and improve system accuracy.

Description: 在Windows操作系统中，任务栏的右边(托盘)会常驻几个图标，如输入法切换图标、音量控制图标等，此外我们还经常遇到具有托盘图标的软件，如金山词霸、实时监测功能的杀毒软件等。这些软件在后台运行，通常不占用太多的屏幕资源，只在通知栏上放一个小小的标志，必要时我们可以通过用鼠标点击图标对其进行选单操作或激活其主窗口。该源代码给出了具体实现托盘程序-the Windows operating system, the right side of the task bar (tray) Permanent several icon, if the input method icon switch, volume control icon, in addition, we have also encountered with the software tray icon, if free email, real-time monitoring functions of antivirus software.

Description: 看了袁渊先生在VC知识库《在线杂志》第14期发表的文章《基于TCP/IP的局域网多用户通信》，感觉受益颇多，但也觉得里面有一些不太完善的地方，具体来说主要有：
1、两个服务器单独运行，且主线程均阻塞，用户界面死锁，不便于控制；
2、聊天服务器线程和互斥量的使用可能导致死锁；
3、不能实现文件传送（文件传送可不能由服务器转发，否则非把它累趴下不可^-^）；
4、不能由用户进行网络设置，所以在不同的网络使用必须修改源程序等等；
我在此基础上重新设计编写了一个系统
