Hi,
I am using Zeos with Firebird. On application exit, I want to ask user
to commit change if there are any changes on Firebird database. How to
detect if user have made any changes to database, so dialog box only
appear only if needed?

Thanks.

Check out the State and UpdateStatus properties of the Dataset:

EDIT: Just noticed that ZQuery also has a UpdatesPending property.
That seems to be what you need.
