And if you need to effect to go from left to right (rather than up and down), you just need to change some of the values around.

LOCAL lnRow
ThisForm.ScaleMode = 3
ThisForm.DrawWidth = 1
FOR lnRow = 0 TO ThisForm.width 
   ThisForm.ForeColor = RGB(0,0,255-255*lnRow/ThisForm.width)
   ThisForm.Line(lnRow, 0,lnRow,ThisForm.height)
NEXT lnRow

>>>thanks, I had found that link, but didn't want to pay for it as I have never come across an API function that someone wasn't able to help me with. It turns out that using this function with VFP is very difficult due to the way VFP forms hwnds are handled, so I can't use it anyhow. :(
