MORE INFORMATION
================
HLISTBOX implements a new class called CHorzListBox that is derived from
CListBox. This new class automatically updates the horizontal extent of a list
box to that of the longest string included in the list box. It works well with
list boxes that have or don't have the LBS_USETABSTOPS style. An ordinary
Windows list box does not attempt to implement horizontal scrolling of this
nature.
Basically, the CHorzListBox intercepts all messages that would affect the
horizontal extent based on the string lengths. It tracks the extent of all
strings in the list box through an array. Examine the source code for details.

NOTE: The "Lock/Unlock" button on the main dialog locks and unlocks the automatic
updating of horizontal extent for the list box.
