ExtTextOut使用疑问？

[chenhua_chch]

void CMy465456View::OnDraw(CDC* pDC)
{
CMy465456Doc* pDoc = GetDocument();
ASSERT_VALID(pDoc);

CClientDC dc(this);
CBrush rush(RGB(255,0,0));
CBrush *oldrush=dc.SelectObject(&rush);

CPen pen;
pen.CreatePen(PS_SOLID ,1,RGB(255,0,0));
CPen *oldpen=dc.SelectObject(&pen);

dc.ExtTextOut(50,50,ETO_OPAQUE,CRect(50,50,200,200),_T("fefefef"),NULL);

dc.SelectObject(oldpen);
dc.SelectObject(oldrush);
// TODO: add draw code for native data here
}怎么改变不聊字符的颜色，和背景颜色1

dc.SetBkColor(RGB(255, 0, 0));
dc.SetTextColor(RGB(0, 255, 0));
dc.ExtTextOut(50,50,ETO_OPAQUE,CRect(50,50,200,200),_T("fefefef"),NULL);
