You can save the ADO RecordSet contents as a file using the RecordSet.Save() method.
You can use the rs.Open method to open the file later.

For ADO 2.0 and 2.1, Save() creates a file with a proprietary format.

ADO 2.5 allows the Save() method to create an XML file. That's more flexible, so I would suggest getting 2.5 if you don't already have it. The format is well-formed XML, with a schema included in the file.

For better info than I can give you here, see the ADO help
From w/in VB, add the ADO library you want to use to the project references and then from the Object Browser, select the object you want help with (RecordSet, e.g.). Right-click and select help.
