如何使用MFC库函数画圆，矩形等图形的边框

当然可以了：
void CFirstMFCView::OnDrawCircularity()
{
// TODO: Add your command handler code here
CClientDC myDC(this);
OnPrepareDC (& myDC);
CBrush *pOldBrush, *pBrush;
pOldBrush = (CBrush *)myDC.SelectStockObject(NULL_BRUSH);
myDC.Ellipse(60,60,200,200);
myDC.SelectStockObject(pOldBrush);
}

//画矩形函数
void CFirstMFCView::OnDrawRectangle()
{
// TODO: Add your command handler code here
CClientDC myDC(this);
OnPrepareDC (& myDC);
CBrush *pOldBrush, *pBrush;
pOldBrush = (CBrush *)myDC.SelectStockObject(NULL_BRUSH);
myDC.Rectangle(150,150,350,200);
myDC.SelectStockObject(pOldBrush);
}
