Smart-Type is thread safe and MDI compatible - you can have multiple controls enabled per window, and you can have several threads started at once!
Smart-Type supports scrolling through matching words or phrases using the up and down arrows. You can put a browse on your screen and Smart-Type enabled fields can simulate a locator in the browse so your users can see what other options exist ...
The Smart-Type demo comes with two word lists - an English one based on public domain English word lists, and one with phrases that we use internally to write histories for veterinary patients.
