Remarks
Called by the framework to determine the relative position of a new item in the list-box portion of a sorted owner-draw combo box. By default, this member function does nothing. If you create an owner-draw combo box with the LBS_SORT style, you must override this member function to assist the framework in sorting new items added to the list box.
