VBScript to interrogate an Access database
I want to extract all the fields associated to my tables in my access database, to get an inventory of all the data objects. This has to populate a form I've created. I've copied an extract of code to determine whether an object in the database is a query or a table and I would like to alter this, if possible.
Any help will be appreciated

Check out the source code in this answer. You should be able to modify it to do what you need. Unless, as Remou pointed out in his comment, you are working with a pre-2000 version of Access.
