[AccessD] Trapping a Check Box

[Rocky Smolin]

Dear List(s):

I have a form the record source of which is a non-updateable query.  On the
continuous form are two check boxes which need to be updated. No problem.
In the Mouse Down event, I take care of everything that needs taking care
of when the state of the check box changes.

However, there are some records where those check boxes need to be kept at
false and I know what the condition is to test to know whether a change
from false to true is illegal (if they were text boxes, it would be simple
- use conditional formatting to make those boxes disabled. But that would
be too easy. No conditional formatting on a check box).

I've tried a few things in my MouseDown event to keep that check box false
but have failed to find the solution. :o(

Does anyone know how to do this?
