接上一篇《C# 高仿腾讯QQ (Bottom控件美化) 》

这篇来说一下QQ皮肤TextBox控件的美化：

(1)．已修正每次窗口最小化以后再还原会发现窗口底部往下移了几十个像素（但还不十分完善，在设计模式时有BUG，请高手支招）

效果图如下:

说明：

（1）新增一个自定义控件（ALTextBox.cs），在上面放一个TextBox控件,把控件的边框属性设为无 (BorderStyle==BorderStyle.None);

　　（2）准备一张带有5个状态的按钮图片如

　　分别对应5种状态，通过重写OnPaint方法把相应的状态图画进去(其实有几种状态用不到，大家自己去修正吧)

　　 //枚举按钮的状态
   　 public enum State
   　　 {
       　　Normal = 1,//按钮默认时
       　　MouseOver = 2,//鼠标移上按钮时
       　　MouseDown = 3,//鼠标按下按钮时
       　　Disable = 4,//当不启用按钮时（也就是按钮属性Enabled==Ture时）
       　　Default = 5//控件得到Tab焦点时
    　　}
