The only easy way that I can think of would be to store a selection-state flag
in the item handle for each listbox item.  When you receive an LN_SELECT or
LN_ENTER message, repeatedly send LM_QUERYSELECTION messages to the listbox to
query all of the selected items and compare each with the selection state.  The
one item that is returned from LM_QUERYSELECTION but whose flag is FALSE is the
one that was selected.

If you need more help regarding this, let me know offline.
