Xor function behavior

I am using the Xor function behavior in a device context with the following method: CDC::SetROP2(XORPEN). It works quite well as far as drawing lines is concerned, but doesn't work with  text.
My problem is that I want this behavior for a line and a text simultaneously. How is it possible?
Thanks, Nicolas,

You cannot alter text output using SetRop2.
You may want to call PatBlt function with
PATINVERTand approapriate brush selected
into that device context after drawing text and line.

I have tried to use the PatBlt function, but it doesn't work.What I have tried to do is :            
MyObject::Draw(CDC* pDC)
{
....
CBrush myBrush = pDC->SelectBrush(backgroundBrush);
CSize      TextSize = pDC->GetTextExtent(myText);
pDC->TextOut(x,y, myText);
pDC->PatBlt(x,y,TextSize.cx,TextSIze.cy,PATINVERT)
}
The function Draw is called twice : one for drawing, one for erasing, and it doesn't work properly
