Thank you.
Having searched my system I believe I did connect to an Access database in 2008 (clearly using an earlier version of Access compared to Access 2010 I now am using)
The dsn definition was 
$dsn = "DBI:ODBC:PROVIDER=MSDASQL;DRIVER={Microsoft Access Driver (*.m
+db)};DBQ=" . $db_name;

[download]
or 
$dsn = "DBI:ADO:PROVIDER=MSDASQL;DRIVER={Microsoft Access Driver (*.md
+b)};DBQ=" . $db_name;

[download]

The connect Perl row was
DBI->connect($dsn, "", "") or ($dbh_ok = 'no');

[download]

I did try one of the dsn defintions suggest (it is below) there are some small differences however I got exaclty the same error messages.
$dsn = 'dbi:ODBC:Driver={Microsoft Access Driver (*.mdb, )};DBQ=' . $d
+b_name;

[download]
I am not sure which worked but I think one of them did since the Perl writes the meta data for the database and there is a file of this as well.
When I use the code now I get the following error messages for the ODBC version - I could not use the ADO since ADO was no longer there.

DBI connect('PROVIDER=MSDASQL;DRIVER={Microsoft Access Driver (*.mdb)};DBQ=FULL PATH TO Access Databse\StockH.mdb','',...) failed: MicrosoftODBC Driver Manager Data source name not found and no default driver specified (SQL-IM002)

Therefore it looks like Access 2010 needs something different to what was successful for a previous version of Access.

Can anyone tell me what I should be using for this?
