这个错误是编写一个在状态栏中加载进度条时出现的错误,解决方法如下:

 

StaAfx.h 中加入#include <afxpriv.h> 头文件

 

 

#define VC_EXTRALEAN // Exclude rarely-used stuff from Windows headers

 

#include <afxwin.h>         // MFC core and standard components

#include <afxext.h>         // MFC extensions

#include <afxdisp.h>        // MFC Automation classes

#include <afxdtctl.h> // MFC support for Internet Explorer 4 Common Controls

#ifndef _AFX_NO_AFXCMN_SUPPORT

#include <afxcmn.h> // MFC support for Windows Common Controls

#include <afxpriv.h>

#endif // _AFX_NO_AFXCMN_SUPPORT
