哪位大神給看一下，listview排序的問題，
//處理單擊訊息
case WM_NOTIFY:
NMHDR * pNMHDR= (NMHDR *) lParam;
listview=GetDlgItem(hWnd,IDC_LIST1);
if(pNMHDR->code==LVN_COLUMNCLICK)
{
//LPNMLISTVIEW pNMLV = reinterpret_cast<LPNMLISTVIEW>(pNMHDR);
NMLISTVIEW *pNMListView = (NMLISTVIEW*)pNMHDR;
ListView_SortItems(listview,CompareFunc,(LPARAM)pNMListView->iSubItem);
if(sort_type==false)
sort_type=true;
else
sort_type=false;
break;
}
//回呼函式撰寫
int CALLBACK CompareFunc(LPARAM lParam1, LPARAM lParam2, LPARAM lParamSort)
{
static TCHAR szBuf1[50], szBuf2[50];
int ret;
ListView_GetItemText(listview, lParam1, lParamSort, szBuf1, 50);
ListView_GetItemText(listview, lParam2, lParamSort, szBuf2, 50);
if(sort_type)
{
ret = lstrcmp(szBuf1, szBuf2);
}
else
{
ret = -lstrcmp(szBuf1, szBuf2);
}
return ret;
}
//往listview里邊添內容
LVITEMA item1
Info info[4];//定義一個結構體,期中只有一個TCHAR s1[max_path];
ZeroMemory(&info,sizeof(info)/sizeof(Info));
HWND list1=GetDlgItem(hwnd,IDC_LIST1); //得到listview句柄
ZeroMemory(&item1,sizeof(item1)/sizeof(LVITEMA));
int ItemCount = ListView_GetItemCount(list1); //得到listview行數
item1.mask=LVIF_TEXT|LVIF_PARAM;
item1.iSubItem=0;
item1.iItem=ItemCount;
item1.pszText=info[0].s1;
int j=ListView_InsertItem(list1,&item1);
item1.lParam=j;
for (int i=1; i<4; i++)
{
item1.iSubItem=i;
ListView_SetItemText(list1,j,i,info[i].s1);
}

關于listview的單擊排序問題回頭給你發我以前的一段代碼
用STL標準庫
