Some of my queries with Unidaq (Locates, field lookups and updates) take a few seconds to implement.

What is the best way to implement an activity indicator when these are initiated? 

Can I use events to kick off showing, displaying, updating, and eventually hiding an activity indicator?

Would that event need to be in a thread or should I be running the database process in a thread, and running the activityindicator in the main thread?

Implementing at the database table level would be a great way to not bloat out the code elsewhere every time there is a database interaction.
