基于winsocket的框体Server和Client

   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。。。

  1. 第一步利用VS2008创建一个Windows窗体应用程序chatServer(过程略);
  2. 设计你的窗体,简单的设计了一个窗体
    基于winsocket的框体Server和Client
    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;
  3. 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;
