Anyone know any good links to articles that explain the differences in the multiple versions of ADO, specifically 2.1, 2.5, and 2.7?  I just inherited a bunch of systems that all use different versions and I want to get them in sync for development and support reasons.....

Is it possible to develop applications using two different versions of ADO on your PC?  That is what I really need to know...

You will not be able to make a reference to two different ADO versions in the same application the CLASSID and name are the same (unlike XML).  What you may be able to do (totally untested, as I have never needed to do this) is refer to say version 2.6 and then do the following:

Dim rs26 As ADODB.Recordset

Dim rs20 As ADODB.Recordset15

This last object is normally hidden in the object browser, but can be exposed by right-clicking and selecting "Show Hidden Members"
