try then next

CPoint **CMyDoc::GetTwoLastPoints()
{
 CPoint **points;
 points= new (CPoint*)[2];
 points[0]=(CPoint*)m_oblPoints.GetTail();
 //Code for second point...
 return points ;
}

first:it should be
points= new (CPoint*)[2];

scond: it should be
points[0]=(CPoint*)m_oblPoints.GetTail
or
points[1]=(CPoint*)m_oblPoints.GetTail

CPoint **CMyDoc::GetTwoLastPoints()
  {
            CPoint **points;
            points= new (CPoint*)[2];

           // points should be first alloced memory before
          //  it's elements are assigned values else program
          //  will give memory fault

            points[0]=(CPoint*)m_oblPoints.GetTail();
            points[1]=(CPoint*)m_oblPoints.GetTail ();

            return points ;
}
