为什么我想在窗口填充位图，却把自己定义的menu遮住了

Question

用了下面的代码就看不到比如“文件”，“编辑”等选项了～
谢谢！！
void CSnakeView::OnDraw(CDC* pDC)
{
    CSnakeDoc* pDoc = GetDocument();
    ASSERT_VALID(pDoc);    m_pDC = pDC;    CRect rect;
    GetClientRect(&rect);//  draw boundary    CBitmap bmpBrick;
    bmpBrick.LoadBitmap(IDB_BRICK);
    CBrush brBrick;
    brBrick.CreatePatternBrush(&bmpBrick);
    CBrush *pBrOld = pDC->SelectObject(&brBrick);
    pDC->PatBlt(rect.left, rect.top,
                rect.Width(), rect.Height(),
                PATCOPY);
    pDC->SelectObject(pBrOld);//  draw interior field    CBitmap bmpCell;
    bmpCell.LoadBitmap(IDB_CELL);
    CBrush brCell;
    brCell.CreatePatternBrush(&bmpCell);
    pBrOld = pDC->SelectObject(&brCell);
    pDC->PatBlt(rect.left+32, rect.top+32+32,
                rect.Width()-64, rect.Height()-64-32,
                PATCOPY);
    pDC->SelectObject(pBrOld);
}
