希望这不是MFC的BUG。

CMainFrame* cFrm = (CMainFrame*)::AfxGetMainWnd();
CString strValue1 = cFrm->mcListCtrl.GetItemText(int(lParam1),cFrm->Column);
CString strValue2 = cFrm->mcListCtrl.GetItemText(int(lParam2),cFrm->Column);
int a = atoi(strValue1);
int b = atoi(strValue2);
if( a==b ) return 0;
return a>b? 1: -1;

我跟踪了排序，它得到了：703》558》400》92

但是，显示的时候却变成了，703在前，400随后，然后是92，最后是558，

怎么回事？

以上为CLISTCTRL的排序。

你自己的BUG

[思危]

看不明白你说的，不过是否ListCtrl有 Sort风格

[chocobo]

mcListCtrl.Create( WS_CHILD | WS_VISIBLE | LVS_REPORT | LVS_SORTASCENDING,
CRect(22,42,624,121), (CWnd*)&DialogBar, IDC_LIST1);
mcListCtrl.ModifyStyleEx(0, WS_EX_CLIENTEDGE, SWP_DRAWFRAME);

而且每次排序最后的结果很可能不同。

函数如下
int CALLBACK ListCompare(LPARAM lParam1, LPARAM lParam2, LPARAM lParamSort)
{
CMainFrame* cFrm = (CMainFrame*)::AfxGetMainWnd();
CString strValue1 = cFrm->mcListCtrl.GetItemText(int(lParam1),cFrm->Column);
CString strValue2 = cFrm->mcListCtrl.GetItemText(int(lParam2),cFrm->Column);
int a = atoi(strValue1);
int b = atoi(strValue2);
if( a==b ) return 0;
return a>b? 1: -1;
}

你全写错啦！！！MSDN里的例子也是错的（误导）！！！

//******************************************
Example of CListCtrl::SortItems(...) in MSDN
By Ivor S. Sargoytchev

The given example in the documentation of CListCtrl::SortItems(...) shows us exactly the WRONG way of using the function.
//******************************************

int CALLBACK CSCListCtrl::CompareFunction( LPARAM lParam1, LPARAM lParam2, LPARAM lParamData )
{
CSCListCtrl* pListCtrl = (CSCListCtrl*) lParamData;

LVFINDINFO pInfo1, pInfo2;
pInfo1.flags = LVFI_PARAM;
pInfo2.flags = LVFI_PARAM;
pInfo1.lParam = lParam1;
pInfo2.lParam = lParam2;
int ind1 = pListCtrl->FindItem(&pInfo1);
int ind2 = pListCtrl->FindItem(&pInfo2);
CString strItem1 = pListCtrl->GetItemText(ind1, pListCtrl->m_iSortColumn);
CString strItem2 = pListCtrl->GetItemText(ind2, pListCtrl->m_iSortColumn);

return pListCtrl->m_bSortAscending ? lstrcmp( strItem1, strItem2 ) : lstrcmp( strItem2, strItem1 );
}
