I would imagine the logical way to do this, would be to make CLine called Line ( the C standard is for MFC classes, and is dumb ), and to have no base class. Your window should keep a collection of Line objects, and iterate over it in your Paint event and draw the lines. As it stands, it sounds like you're creating child windows, which is not wise, if you want the lines to exist inside your SDI window and be attached to it.
