How can I automatically add an Autonumber field to a table in Access 2007?

[Paldrion]

I will need it to be in VBA, since I need to put it in an Access 2007 database and execute it with an Access macro.

What I am doing is using a utility to find the hard drives' conditions on computers and list them in a text file sequentially. The utility does not list numbers or drive letters. So I need to put some kind of identifying information on the entries so I can put them in the appropriate spot in the Access Database record.

I need the number to come out as such:
First record found | 1
Second record found | 2
and so forth.

Thanks for your help.

I figured it out. Instead of appending the imports to an existing table, I can Import them as new tables, let Access add a primary key, and then automate the imports.

Thanks anyway.
