前面写了一个简单的管理电脑创建的WIFI热点的工具，整体比较简单，只是由一个图片，和2个button，还有一个MessageBox组成，这两天又完善了下，主要更新了以下几个方面：
1.使用类来编写代码（由于自己基本还是面向过程思想，有必要学习下类的基本写法）
2.将版本1中的MessageBox改为由ListBox和Scrollbar组成的frame，这样信息可以一直显示在listbox里面。
3.增加了菜单栏，并添加了一些子菜单。
4.程序窗口固定，退出需用户确认。
下面是源代码：

下面是运行后的结果：
点击open/close按钮会打开或关闭WIFI，并在下面的消息框内输出提示信息，右侧的滚动条可以进行上下移动，如下图所示：
菜单栏里的help会显示一些信息：
Option里的Hide Message会隐藏下面的消息框，而点击Show Message则又会重新显示出来：
而点击Exit子菜单和右上角的关闭图标，都会弹出对话框，让用户进行确认：
