OldValue

P: n/a
In A2k3 is it possible to determine if the OldValue property for a check box
exists using code?

Thanks.

Keith, the simplest approach would be to just refer to the OldValue
property, and use error-handling to recover if the property doesn't apply.

There are too other factors to consider, such as whether the check box is
part of an option group (examine its Parent property), or bound to a
non-updatable field, or whether the check box is unbound (in which case the
OldValue does not generate an error, but is not useful), and so on.

Thanks Allen, I'll look into that.

Duly noted, thanks.
