自己写的一个Edit控件的扩展类（源码）修改版
2010年01月17日 星期日 下午 04:35
#if !defined(AFX_COOLEDIT_H__3F4B9BD7_EFF9_45F5_AD79_EEF2B95742B3__INCLUDED_)
#define AFX_COOLEDIT_H__3F4B9BD7_EFF9_45F5_AD79_EEF2B95742B3__INCLUDED_
#if _MSC_VER > 1000
#pragma once
#endif // _MSC_VER > 1000
// CoolEdit.h : header file
//
/*
作者：段晓辉
版本：2.0
功能：对标准的Edit控件进行扩展，可以在标准的控件中加入小位图，
并可以改变背景、文字的颜色和文字的字体。
接口： void SetEditFont(LPLOGFONT lpFont);////功能：设置编辑框的字体
void SetTextColor(COLORREF textColor);//功能：设置编辑框字体的颜色
void SetBkColor(COLORREF bkColor);//功能：设置编辑框的背景颜色
void LoadBitmap(UINT bmpID);//功能：在编辑框内增加位图
void SetClearBk(BOOL bClearBk = TRUE);//功能：设置是否对图标的背景进行去除操作,默认为清除。
void SetClearColor(COLORREF clearColor = RGB(255, 255, 255));//设置要去除的颜色。
修改： 1、修改了小图标不能和编辑框相匹配的问题
2、修改了当改变编辑框背景色时，图标有边框(背景)的问题
