使用DC画笔的典型步骤

 

 

       CDC* pCurDC=m_PicView.GetDC();

 

       CPen* pOldPen=NULL;

 

       //生成并载入画笔

       CPen penBound;

       if (RED==color)     penBound.CreatePen(PS_SOLID,m_nEdgeWidth,RGB(255,0,0));             else         penBound.CreatePen(PS_SOLID,m_nEdgeWidth,RGB(0,255,0));

 

pOldPen=pCurDC->SelectObject(&penBound);

       pCurDC->Rectangle(&rcTest);

 

       //恢复默认画笔并注销创建的画笔

       pCurDC->SelectObject(pOldPen);

       pCurDC->SelectObject(pOldBrush);

       penBound.DeleteObject();

 

//释放DC资源

       m_PicView.ReleaseDC(pCurDC);
