Oops, sorry.  I just couldn't imagine that anyone was really having
problems with lists in modeless dialogs.  They're incredibly easy.

You ought to do it after IsDialogEvent and before DialogSelect.  On the
other hand, you don't really *have* to do it at all.  If you don't,
your scroll bar(s) will still show and that's the extent of the
problem.  Most users won't even notice.
