No, there is no strike through font ability in Access.

You could simulate it to some extent, by using a line control the same size
as the text control.  Setting the visible property of the line control to
true or false as required.

If you check out Stephen Lebans' site you might find something there to do
what you want, or at least you might find a way to resize the line control
to match the length of the text.
