Description: CSerialPort是一个很好的串口通讯类，但它没有关闭串口的方法，如果对这个类的实现原理不了解，自行编写串口关闭方法可能会带来如下问题：
1、用closehandle方法关闭串口：由于调用类方法StartMonitoring后会生成一个串口通信线程，这个线程中要不停地访问串口，这种方法会带来明显的错误。
2、先用StopMonitoring方法停止串口监听，然后用closehandle关闭串口：由于StopMonitoring只是将进程挂起，这样做将使程序结束时解构函数无法将中止事件发送到线程，可能导致程序不能完全退出，主窗口关闭后仍可在进程管理器中看到进程。
3、先用SetEvent发送中止事件给线程，等待线程结束后再用closehandle关闭串口，程序如下：-CSerialPort class is a good serial interface communication, but it has no closing method of the serial port, if you don t understand the implementation principle of this class, to write a serial port closure method may lead to the following questions:
1, close a serial port with the closehandle method: as the call after class methods StartMonitoring generates a serial port communication thread, the thread to keep access to a serial port, this method can bring obvious errors.
2, use StopMonitoring method first stop serial port to monitor, then use closehandle close the serial port: because StopMonitoring just hang up the process, doing so will make the program at the end of the destructors cannot send to suspend the event to the thread, may cause the program can t quit, main window is turned off, can still be seen in the process in task manager.
3, with SetEvent first send the thread to suspend the event, after the waiting thread to use closehandle to close a serial port,

Description: 这个程序是一个非常干净的代码，由有经验的程序员编写，使用C ++类cSocket，在C ++平台上编写，并且附带一个MFC演示应用程序。
cSocket类很容易使用，即使是初学者也没有问题。(Event driven (non blocking, asynchronous) Winsock programming is a very complex topic. It is definitely NOT for beginners!
I needed such code and searched the internet for a TCP communication class which is ready to use.
But all I found (even here on CodeProject) was either buggy, immature beginner code or much too complex for my needs.
So I ended up - investing many hours - to write my own decent class.
I offer it here on CodeProject for all those who need a reliable and robust TCP socket class.
What you can download here is a very clean code written by an experienced programmer, with proper error handling and plenty of comments.
The universal generic C++ class cSocket, written in plain C++, comes with a MFC demo application.
The cSocket class is so easy to use that even a beginner will have no problems with it.)
