Primary key warning messages

[Terrence Carroll]

I was wondering if it is possible to implement an error handling feature
where the user is alerted he is attempting to import duplcate values to a
primary key field while still haveing the warnings property set to NO. Any
advice on how to do this would be great.

Thanks,

Terry Carroll

Hi

You could use the indexing in the table to disallow the additions.
Or
You could could use a simple popup message

But - - -
The idea of a primary field is that it can't/shouldn't allow duplicates - so
best to use the indexing feature in the table for this (eg. Allow duplicates
= No)

What is it that you are expecting the user to do if there is a duplicate key
situation? Access won't overwrite an existing key, so it seems like the
only reason to handle it is to let the user know there's something wrong.

Do you need to do that? Not a rhetorical question ... if you want to add
records to your table, but not add records that have a duplicate key, you
can do that without ever bothering the user.

More info, please...
