I want to create an interface using
Quick question : how do I validate uniqueness in a TDataset ? I have some
data aware controls and a TDBNavigator; I can check other validation stuff
in the BeforePost event, but is there a sensible way of testing whether the
field name (which has a unique constraint in the database) already
The most basic way of doing this would be to do a bit of sql in your
BeforePost event and see if that field is already used. If you don't
know anything about the data underneath the TDataSet then this could be
a bit tricky.

Aye, we get bitten that way a lot also, for the same reasons.
Don't handle sending emails yourself. Send them to a good local mail
system such as postfix on Unix and that will deliver your mail much
more reliably.
