如何实现画多边形，画弧和画扇形

Answer 1

void CMFCDrawingView::OnDraw(CDC* pDC)
{
CMFCDrawingDoc* pDoc = GetDocument();
ASSERT_VALID(pDoc);
if (!pDoc)
return;

DrawGraphics(pDC);
// TODO: 在此处为本机数据添加绘制代码
}
void CMFCDrawingView::DrawGraphics(CDC * pDC)
{
//定义画笔
CPen oPen(PS_SOLID, 1, RGB(255,0,0));
CPen * pOldPen = pDC->SelectObject(&oPen);

POINT aPoint[6] = {{10,10},{20,20},{40,50},{50,40},{30,20},{10,10}};
pDC->Polygon(aPoint, 6);

pDC->Ellipse(100,100,210,210);

pDC->Pie(200,200, 250, 250, 200,200, 225,225);

pDC->SelectObject(pOldPen);

}
