CListCtrl::SortItems
This method sorts list view items using an application-defined comparison function. The index of each item changes to reflect the new sequence.

BOOL SortItems(
PFNLVCOMPARE pfnCompare,
DWORD dwData );
Parameters
pfnCompare
Specifies the address of the application-defined comparison function. The comparison function is called during the sort operation each time the relative order of two list items needs to be compared. The comparison function must be either a static member of a class or a standalone function that is not a member of any class.
dwData
Specifies the application-defined value that is passed to the comparison function.
Return Value
Nonzero if it is successful; otherwise, it is zero.

Remarks
The comparison function has the following form:

int CALLBACK CompareFunc(LPARAM lParam1, LPARAM lParam2,
LPARAM lParamSort);

The comparison function must return a negative value if the first item should precede the second, a positive value if the first item should follow the second, or zero if the two items are equivalent.

The lParam1 and lParam2 parameters specify the item data for the two items being compared. The lParamSort parameter is the same as the dwData value.

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.
CListCtrl* pmyListCtrl;

// Sort the list view items using my callback procedure.
pmyListCtrl- >SortItems(MyCompareProc, (LPARAM) pmyListCtrl);
}
comparefunc的lparam1,lpram2 就是lvitem 的lParam项，在insertitem的时候设置，或者用SetItemData设置（第二个参数)
