ListBox Header Alignment

Can someone tell me how to align a header cell on a listbox to be right aligned? I have a currency value listbox and the currencies are aligning correctly to the right (having used the ListBox.AlignRight value for the cell alignment), but the header looks stupid still sitting to the left.

How do I change this?

Thanks

Phil

me.ColumnAlignment(1) = Listbox.AlignRight

makes Column 1 and Header 1 align right

Thanks Axel - works a treat
