CClientDC dc(this);

CPen pen(PS_SOLID,5,RGB(255,0,0)); //红色实线画笔，决定画图的边线

CPen *pOldPen=dc.SelectObject(&pen);//画笔选入设备描述表

CBrush *pBrush=CBrush::FromHandle((HBRUSH)GetStockObject(NULL_BRUSH));

//创建空画刷，防止遮挡内容

CBrush *pOldBrush=dc.SelectObject(pBrush);//选择画刷

dc.Rectangle(CRect(m_OrigPoint,point)); //画矩形

dc.SelectObject(pOldBrush);

dc.SelectObject(pOldPen);
