You can't do it programatically but you can configure Access to cascade the updates and deletes.

From the menu, choose Tools - Relationships. Select a relation, right click on it and select Edit Relation. You can choose what items you want done. When records are deleted or updated in the Access database, the Jet engine will take care of this for you. It is not a trigger but it will do this limited job for you.
