I see two approaches, you can either

Generate the report data directly querying on multiple databases (see "Queries from multiple databases on the same server"[^].

or

Retrieve all the needed data from each database (with independent queries) and then generate the report with VB6 code.

Are all of your databases running on the same SQL Instance?

If so, you should be able to write a script that will combine all of them.

What kind of data are you looking to generate? Are there any relationships between them (Primary keys, etc)?
Depending on what you are looking for you may be able to write something Like (this is if both databases are on the same instance)

SELECT Database1.dbo.items.Price, Database2.dbo.Items.Cost
FROM Database1.dbo.items INNER JOIN Database2.dbo.Items ON
Database1.dbo.items.ID = Database2.dbo.Items.ID
