OnOK
Slightly different than CListCtrlStylesDlgEx's handling of the updated
style bits. Whereas that class dynamically tracks the style bits, this
one just waits until the user is done. Then we run through the
entire list control items and create the new styles that should be applied
to the list control back in the main dialog.

Returns
void

OnInfoTip
This is a hand-entered handler for the LVN_GETINFOTIP WM_NOTIFY message
which we enabled by including LVS_EX_INFOTIP in the extended style
bits of the list control. When this style bit is enabled, it sends
the parent window a LVN_GETINFOTIP message with a pointer to a
LVGETINFOTIP struct. We populate the pszParam of this struct with
documentation for the item selected. A more robust implementation might
associate the data member of each list control item with a string
allocated on the heap or some user defined struct.
