上面的错误是什么，怎么修改？
先谢了！

Answer 1

在cdromcontroldlg.h中
最开头加入 #ifnedf _CDROMCONTROL_H
           #define _CDROMCONTROL_H结尾加入   #endif

Answer 2

重复定义了
#pragma once

我按照你方法，编译结果还有两个错误，如下：

在CDROMControl.h加入的代码为：
class CCDROMControlDlg : public CDialog
{
protected:
HICON  m_hIconArray[4];
int    m_nIconPos;
BOOL   m_bIsFirstMinimized;
BOOL   m_bIsMinimized;

afx_msg void OnTimer(UINT nIDEvent);
afx_msg void OnWM_NOTIFYICON(WPARAM wParam,LPARAM lParam);
DECLARE_MESSAGE_MAP()
};
在CDROMControl.cpp中加入的代码为：
#define WM_NOTIFYICON  WM_USER+1
#define IDC_NOTIFYICON WM_USER+2 BEGIN_MESSAGE_MAP(CCDROMControlDlg,CDialog)
