I need to implement a 3 state checkbox. I would prefer the 3 states to show
<blank>,<check>,<crossed>. (At the moment I have a standard checkbox bound
to a boolean field).

How would you implement this? What would you recommend?

Hi David.

Firstly you probably know you will need to use a Number field, since the JET
boolean does not support triple state.

The Access check box does not differentiate Checked and Crossed either, so
you will need to use a text box, with the WingDings font to get the display
you want. With an appropriate size and border, it could look like a check
box.

I suppose you could store the ASCII value for the WingDings character as the
actual data in the field, but it may be easier to use an unbound text box,
and use the events to reassign the data programmatically.

Haven't actually done that, but I was thinking about it just yesterday.
