// This file was created on March 21st 2001 by Robert Brault. 
// I created this Class to be able change the Color of your Edit Box 
// as well as your Edit Box Text. This is Derived from CEdit so you 
// do not have all the overhead of a CRichEditCtrl. 
// 
// There are three functions available Currently: 
// SetBkColor(COLORREF crColor) 
// SetTextColor(COLORREF crColor) 
// SetReadOnly(BOOL flag = TRUE) 
// 
// How To Use: 
// Add three files to your project 
// ColorEdit.cpp, ColorEdit.h and Color.h 
// Color.h has (#define)'s for different colors (add any color you desire). 
// 
// Add #include "ColorEdit.h" to your Dialogs Header file. 
// Declare an instance of CColorEdit for each edit box being modified. 
// Ex. CColorEdit m_ebName; 
// 
// In your OnInitDialog() add a SubclassDlgItem for each CColorEdit member variable. 
// Ex. m_ebName.SubclassDlgItem(IDC_EB_NAME, this); 
// In this same function initialize your color for each box unless you want the default. 
 
 
// ColorEdit.cpp : implementation file 
// 
 
#include "stdafx.h" 
#include "ColorEdit.h" 
#include "Color.h" // File Holding (#define)'s for COLORREF Values
