While the Polyline() method starts the first line at lpPoints[0], the PolylineTo() member

function does not control the beginning of the first line. Like the LineTo() method, it

simply starts drawing, which would mean it starts at the origin (0, 0). For this reason, if

you want to control the starting point of the PolylineTo() drawing, you can use the

MoveTo() method:

void CExoView::OnDraw(CDC* pDC)

{

CPoint Pt[7];

Pt[0] = CPoint(20, 50);

Pt[1] = CPoint(180, 50);

Pt[2] = CPoint(180, 20);

Pt[3] = CPoint(230, 70);

Pt[4] = CPoint(180, 120);

Pt[5] = CPoint(180, 90);

Pt[6] = CPoint(20, 90);

pDC->MoveTo(20, 30);

pDC->PolylineTo(Pt, 7);

pDC->LineTo(20, 110);

}
