新手：一个很菜的问题--如何继承一个CEdit控件。在线！

[daluqingfeng]

我建了一个新的类，如下:
#include <afxwin.h>
#include "stdafx.h"
#include "resource.h"

class CMyEdit :public CEdit
{
public:
CMyEdit();
virtual ~CMyEdit();

};

错误如下：
Compiling...
MyEdit.cpp
d:\workarea\myworkarea\vs6work\testprject_second\resource.h(17) : warning C4005: 'IDC_STATIC' : macro redefinition
c:\program files\microsoft visual studio\vc98\mfc\include\afxres.h(290) : see previous definition of 'IDC_STATIC'
Linking...

Debug/TestPrject_Second.exe : fatal error LNK1120: 2 unresolved externals

为什么？？？？？
谢谢各位高手！！

你是什么类型的工程?
用了MFC么。

Win32 Application

我知道了是不能用CEdit，可是我要在Win32 Application中继承一个Edit控件用什么呢

自己写一个吧.

你看mfc的实现不都是消息吗
