Multiline ListBox

I have seen several similar messages posted but none had an answer. I just hope that someone answers to this one because I am running out of time.
My primary concern is to create a list box in a dialog box that displays several lines of text as a single item. How can I do this? Do I have to use the OwnerDrawFixed... flag? I know that the items have different lengths, i.e. each item might occupy a different number of lines than the others, maybe OwnerDrawVariable... is better in this case?
Is it posible to avoid the owner draw list box to achieve the above?
I guess my problem is related to subclassing, am I right?
Thank you for your time and your contribution.
Yours
