给大家发布一个例子，我收集的，提供给大家，关于CListBox，见附件
void CListBoxEx::DrawBorders()
{
        //Gets the Controls device context used for drawing
        CDC *pDC=GetDC();
       
        //Gets the size of the control's client area
        CRect rect;
        GetClientRect(rect);
       
        /*
        Inflates the size of rect by the size of the default border
        Suppose rect is (0,0,100,200) and the default border is 2 pixels,
        after InflateRect, rect should be (-2,-2, 102,202) and the border
        will be drawn from -2 to 0, -2 -> 0, 102->100, 202->200.
        */
        rect.InflateRect(CSize(GetSystemMetrics(SM_CXEDGE),
                GetSystemMetrics(SM_CYEDGE)));
       
        //Draws the edge of the border depending on whether the mouse is
        //over or not       
        if (m_bOver)pDC->DrawEdge(rect,EDGE_BUMP ,BF_RECT );
        else pDC->DrawEdge(rect,EDGE_SUNKEN,BF_RECT );
       
        ReleaseDC(pDC); //Frees the DC
}
