[Description]
This class provide a appearance the same as the "Window优化大师".That is
when the mouse move over the edit control,the background turns to White!When the
mouse move out of the edit control,the background turns to the origion color!

[Flaws]
(1)The control is dealing with chinese characters which is two space than the ANSI
character by default.
(2)When the text is overflow .This class couldn't provide an effective way to scroll
the text!
