CListCtrl的衍生類別CMyListCtrl的DrawItem（）函數裡添加代碼

  CDC *pDC = CDC::FromHandle(lpDrawItemStruct->hDC);    if (lpDrawItemStruct->itemState && LVIS_SELECTED)    {        CPen PenLine(PS_SOLID, 1, RGB(0, 0, 0));        CPen *OldPenLine = pDC->SelectObject(&PenLine);        rcItem.right -= 2;        rcItem.bottom -= 2;        pDC->MoveTo(rcItem.left, rcItem.top);        pDC->LineTo(rcItem.right, rcItem.top);        pDC->MoveTo(rcItem.left, rcItem.top);        pDC->LineTo(rcItem.left, rcItem.bottom);        pDC->MoveTo(rcItem.left, rcItem.bottom);        pDC->LineTo(rcItem.right, rcItem.bottom);        pDC->MoveTo(rcItem.right, rcItem.top);        pDC->LineTo(rcItem.right, rcItem.bottom);        pDC->SelectObject(OldPenLine);        rcItem.DeflateRect(2, 2, 2, 2);        COLORREF m_color = RGB(71, 173, 255);        for (int i = rcItem.Height() / 2; i>0; i--)        {            CPen pen(PS_SOLID, 1, m_color);            CPen *OldPen = pDC->SelectObject(&pen);            pDC->MoveTo(rcItem.left, rcItem.top + i);            pDC->LineTo(rcItem.right, rcItem.top + i);            pDC->MoveTo(rcItem.left, rcItem.bottom - i);            pDC->LineTo(rcItem.right, rcItem.bottom - i);            pDC->SelectObject(OldPen);        }        pDC->SetTextColor(RGB(255, 255, 255));    }    else    {        pDC->SetTextColor(RGB(0, 0, 0));        CBrush brush;        brush.CreateSolidBrush(RGB(255, 255, 255));        pDC->FillRect(rcItem, &brush);    }    CString strText = GetItemText(nRow, 0);    CRect rcSubItem;    GetSubItemRect(nRow, 0, LVIR_LABEL, rcSubItem);    pDC->DrawText(strText, rcSubItem, DT_CENTER);
