Sorry, I don't think there is a way to do this, unless you switch everything to the NotesUI... classes. If you do this, Notes internal mechanism may take over to resolve the address. I don't know about this.

You could also build your own picklist functionality. Once the user types in a few keys, they could push the "Resolve" button and you could query a view in the NotesAddressBook for any matching values. If you wanted to get fancy, you could build this search capability into an "on-the-fly" mechanism and perform a search after each keystroke.

However, it seems like a lot of work for something with limited functionality. If the user is sending to a combination of Internet and Notes addresses, you may get some benefit when they type in a NotesAddress. If they only send to Internet addresses, Notes won;t be able to resolve them (and it won't even try). For this reason, I always send using Internet format. The Send process doesn't stop because of an address resolution conflict.

Regards.
