vc 中关于这个SetExtendedStyle的错误

程序代码：
m_ListCtrl.SetExtendedStyle(LVS_EX_HEADERDRAGDROP|LVS_EX_FULLROWSELECT|LVS_EX_TRACKSELECT);
int i=0,iCount;
m_ListCtrl.DeleteAllItems();
CString sz[4]={"Name","Sex","Birthday","Fav"};
for(short ii=0;ii<4;ii++)
{
m_ListCtrl.InsertColumn(ii,sz[ii],LVCFMT_CENTER,80);
}
CStdioFile file;
CString GFilePath="studentInfo.txt";
file.Open(GFilePath,CFile::modeReadWrite);
CString str=" ";
int nCol=0;
int iRow=0;
while(file.ReadString(str))
{
if(nCol==0)
{
m_ListCtrl.InsertItem(iRow,str);
}
else
{
m_ListCtrl.SetItemText(iRow,nCol,str);
}
nCol=(++nCol)%5;
if(nCol==0)
iRow++;
}
file.Close();
运行后的错误：

Answer 1

找一个SP6补丁吧兄弟。你安装的是那种with SP6的VC6吧，但它们确实还是需要SP6补丁的。
最简单的办法，找找看你电脑上的那个头文件中的声明部分，不会有这些函数的。
而你查本机版MSDN是肯定有的。
按照MSDN中对C2039的解释，就是你引用一个不存在的成员的错误。
更新下你的VC6就好了。

Answer 2

把头文件里面的
CListBox m_ListCtrl;
换成
CListCtrl m_ListCtrl;
