Summary:
A list box cannot be changed from single column to multicolumn by
altering the list box's style bits "on the fly."
The effect of switching a single-column list box to multicolumn can be
achieved by creating one single column and one multicolumn list box.
Initially, hide the multicolumn list box. To switch the list boxes,
hide the single-column list box and show the multicolumn list box.
More Information:
In general, programmatically changing the style bits of a window
usually leads to unstable results. The method of switching between two
windows (hiding one and showing the other) can safely switch window
styles.
