如下代码在VC 6.0上执行可以实现排序，但在VS2005上编译不能通过，即使修改后编译通过亦不能实现排序功能！！请问为什么？请高手给于指点！！急用！！谢谢！！
void CTestDateViewDlg::OnColumnclickList1(NMHDR* pNMHDR, LRESULT* pResult)
{
NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
// TODO: Add your control notification handler code here
_subItem = pNMListView->iSubItem;
CListCtrl* pmyListCtrl = NULL;

m_list.SortItems(sortItem, (LPARAM)this) ;
*pResult = 0;
}

int CALLBACK CTestDateViewDlg::sortItem(LPARAM lParam1, LPARAM lParam2, LPARAM lParamSort)
{

CTestDateViewDlg* pDlg = (CTestDateViewDlg*) lParamSort;

CString strItem1 = pDlg->m_list.GetItemText(lParam1, pDlg->_subItem);
CString strItem2 = pDlg->m_list.GetItemText(lParam2, pDlg->_subItem);

return strcmp(strItem2, strItem1);
}

编译的时候报的什么错？
