Hi, The example is the CScribbleView class code for: virtual void OnDraw(CDC\* pDC); // overridden to draw this view afx\_msg void OnLButtonDown(UINT nFlags, CPoint point); afx\_msg void OnLButtonUp(UINT nFlags, CPoint point); afx\_msg void OnMouseMove(UINT nFlags, CPoint point); . If you cannot study this code and understand how it is an answer to your question think of another kind of working area ;) cheers, AR When the wise (person) points at the moon the fool looks at the finger (Chinese proverb)

Hello, sorry for delay. instead of HDC you can use CClientDC. that will work. Regards, A. Gopinath.
