You might consider using the
standard "Hatch brush" HS_DIAGCROSS.
See CreateHatchBrush()

Otherwise, first create a bitmap for it.
You might be able to use MSPAINT to create an 8x8 bitmap.

Then decide what you really want to do with it.
See Help on
	Patern Brush
	Pattern
	Using Pens
See also

	CreatePatternBrush()
	CreateDIBPatternBrushPt()

Here is a complete example of alternate rows in a listview.

   PatBmp = new Graphics::TBitmap();
   PatBmp->Height = 2;
   PatBmp->Width = 2;
   PatBmp->Canvas->Pixels[0][0] = clBtnHighlight;
   PatBmp->Canvas->Pixels[0][1] = clBtnFace;
   PatBmp->Canvas->Pixels[1][0] = clBtnFace;
   PatBmp->Canvas->Pixels[1][1] = clBtnHighlight;

   Canvas->Brush->Bitmap = PatBmp;
   Canvas->FillRect(PaintRect);

Thanks Bob
This works quite nicely.:-)

Do You know if it would be faster if i use a 
bitmap size 8 x 8, not that this is notisable 
slow (on my machine)

Thanks again
Kind regards

I don't know.
I mentioned 8x8 because that was what the help talked about.
But they were showing a larger pattern, too.
