Hello,

I am using ADO in VC++ and have a question on the issue of the #import
call. My application will be run on 98/2000/Me/NT and XP PCs and I am
developing on XP running the latest version of the MDAC <MDAC 2.8 sp1
on windows XP sp2>

I have previously simply used MSADO15.DLL in the #import call but ran
into issues with testing my application on Windows 2000. I was getting
an 0x800A0E7A error when trying to Open the connection - so I
installed the latest MDAC on that PC and all was fine.

On trawling through a few sites and on MSDN I came to the conclusion
that I perhaps should #import one of the many MSADOXX.tlb files but
the question is which one?

What is the "standard practice" for this? Do I #import an old tlb file
or is there an elegant way to check the version of MDAC installed and
warn the users that they need to install a later one <that I can put
on the installation cd>

Many thanks for your time and any help you can give me and I apologise
if this is a basic question.

A
