C makes it easy to shoot yourself in the foot; C++ makes it harder, but when you do, it blows away your whole leg

Did you think about using some sort of a CListView derived class? These are made for exactly this purpose: Giving out texts in a view. OTOH, you might have very good reasons to print directly on the view. Then writing to a Mem-DC and only blitting it to screen in OnPaint would be the way to go.
