前面学了一点Winsock的知识，会编写简单的Server和Client，现在就想通过VS2008编写框体的Server和Client，而不是在控制台上的操作了，毕竟学编程就是要多加练习，在实践中发现不懂的地方，然后解决，然后再发现……
当然，作为一个刚接触Winsock的新手，大部分知识都来自于网上的资料，包括接下来的代码也是借鉴。。。
- 第一步利用VS2008创建一个Windows窗体应用程序chatServer（过程略）；
- 设计你的窗体，简单的设计了一个窗体
注意，每一个组件都需要有唯一的Name，在设置好组件的属性后，可以双击这个组件，则会自动生成对应的动作函数；
- 在Form1.h中写入如下代码，注意里面很多的函数时根据组件Name来命名的，所以copy时需要注意这一点；

- 在chatServer中加入这一行代码：using namespace System::Threading;到此Server就基本完成了。。
- 仿照这样的方法完成Client端
- chatClient过程中Form1.h的代码
