Convert VB project into a DLL

I have a regular VB project that presents a form to the user to allow drilling down into a DB and selection of a single item, a user ID.

The project current has several forms, a class and a module.

Can I make this whole thing into a DLL so I can reuse it easily from other VB programs?

I need to interact with the user while digging into the DB,
but, when done, can close it and just return a single string.

Thanks, DaveBo

WIth multiple forms it might be easier to use ActiveX control instead of activex dll.
