Set Form.ControlBox = false (this also removes the Maximise, Minimise and system menu from the form). You can disable the close box (grey it out, but leave the other info) by overriding the CreateParams method in your form:

    protected override CreateParams CreateParams
        {
        get
            {
            CreateParams parms = base.CreateParams;
            parms.ClassStyle |= 0x200;  // CS\_NOCLOSE
            return parms;
            }
        }
