MFC: how to create a NULL BRUSH

[ylxin1993]

here's part of my class code, the problem is that I can create a null brush,
the BS_NULL can't be a parameter in CreateSolidBrush nor in CreateHatchBrush, what should I do that I can create a null brush?

        CBrush aBrush;
	if(m_brushStyle == BS_SOLID)
	{
		if(!aBrush.CreateSolidBrush(m_brushColor))
		{
                      //....
		}
	} 
	else
	{
		if( aBrush.CreateHatchBrush(m_brushStyle, m_brushColor) )
		{
                     //...
		}
	}

        CBrush* oldBrush = pDC->SelectObject(&aBrush);

I think this would work, but I think it's not good enough.

	CBrush* oldBrush;
	if(m_brushStyle == BS_NULL)
	{
		oldBrush = (CBrush*)pDC->SelectStockObject(NULL_BRUSH);
	} else
	{
		oldBrush = pDC->SelectObject(&aBrush);
	}
