排序最快：
CListCtrl::SortItems
Example

// Sort the item in reverse alphabetical order.
static int CALLBACK
MyCompareProc(LPARAM lParam1, LPARAM lParam2, LPARAM lParamSort)
{
  // lParamSort contains a pointer to the list view control.
  // The lParam of an item is just its index.
  CListCtrl* pListCtrl = (CListCtrl*) lParamSort;
  CString    strItem1 = pListCtrl->GetItemText(lParam1, 0);
  CString    strItem2 = pListCtrl->GetItemText(lParam2, 0);

  return strcmp(strItem2, strItem1);
}

void snip_CListCtrl_SortItems()
{
  // The pointer to my list view control.
  extern CListCtrl* pmyListCtrl;

  // Sort the list view items using my callback procedure.
  pmyListCtrl->SortItems(MyCompareProc, (LPARAM) pmyListCtrl);
}

If you don’t want to allow the users to sort the list by clicking on the header, you can use the style LVS_NOSORTHEADER. However, if you do want to allow sorting, you do not specify the LVS_NOSORTHEADER. The control, though, does not sort the items. You have to handle the HDN_ITEMCLICK notification from the header control and process it appropriately. In the code below, we have used the sorting function SortTextItems() developed in a previous section. You may choose to sort the items in a different manner.
Step 1: Add two member variables
Add two member variables to the CListCtrl. The first variable to track which column has been sorted on, if any. The second variable to track if the sort is ascending
