Hi

We have a number of C++ software components that use ADO (via a #import and
smart pointers).

This code was originally built on machines with ADO 2.5 installed, and
deployed on servers also with ADO 2.5 installed.

We have recently discovered that if you build the code on a machine with a
later version of ADO (in this case 2.6) and then deploy it on the server
running 2.5, the software crashes.

Is there any way in the code to ensure that it remains compatible with
earlier versions of ADO regardless of the version its built with??
(Shouldn't COM prevent this happening!)

Thanks
Simon
