I haven't received jmm's original posting here yet, but concerning
the above:

I believe that the drawIt flag passed to LNew() and subsequently
controlled by LDoDraw() affects only the drawing of the cells
themselves and not the scroll bar(s), giving you something that
looks like an empty list.

I was about to suggest that you first draw the list somewhere outside
the dialog's visible region (similar to HideDItem()) except that
of course there is no easy way to move a list once installed.
I suppose you could SetDItem the list to another location,
change its rView field and MoveControl its scroll bars, but
it seems awfully messy...
