pDC->Polyline(Pt, 7);

}

Besides the Polyline() method, the CDC class provides the PolylineTo() member

function. Its syntax is:

BOOL PolylineTo(const POINT* lpPoints, int nCount);

The lpPoints argument is the name of an array of POINT or CPoint objects. The nCount

argument specifies the number of points that would be included in the figure. Here is an

example:

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->PolylineTo(Pt, 7);

}
