怎么对CListCtrl控件按列进行排序？

有一个CListCtrl控件m_List，它有三列，分别是“学号”、“名字”、“成绩”，现在我想根据某列（比如名字或者成绩）进行升序（降序）排列，要怎么做？请各位大侠不吝指教！在明天中午前解决追加30分！

void CN7SeeView::OnColumnclick(NMHDR* pNMHDR, LRESULT* pResult)

{

int i,nItemCounter;

NM_LISTVIEW * pNMListView = (NM_LISTVIEW*)pNMHDR;

CListCtrl * pListCtrl=&(this->GetListCtrl());

if(!m_bSortable) return;

nColToSort=pNMListView->iSubItem;

if(nLastColToSort!=nColToSort)

{

bDesc=0;

nLastColToSort=nColToSort;

}

else

bDesc=bDesc?0:1;

nItemCounter=pListCtrl->GetItemCount();

for(i=0;i<nItemCounter;i++)

pListCtrl->SetItemData(i,i);

pListCtrl->SortItems(SortLVProc,(LPARAM)pListCtrl);

*pResult = 0;

}

static int CALLBACK SortLVProc(LPARAM lParam1,LPARAM lParam2,LPARAM lParamSort)

{

// lParamSort contains a pointer to the list view control.

CListCtrl* pListCtrl = (CListCtrl*) lParamSort;

CString strItem1 = pListCtrl->GetItemText(lParam1,nColToSort);

CString strItem2 = pListCtrl->GetItemText(lParam2,nColToSort);

if(bDesc)

return strcmp(strItem1,strItem2);

else

return strcmp(strItem2,strItem1);

}
