Hyperlink and Database design

[D. Austin]

I have a database that list various invoice numbers from various vendor #. I
want to link the invoice number to a scanned copy of the invoice located on
the server. The invoices are stored in indivual folders based on the vendor
#. Is there a way to automaticly hyperlink to the proper folder and invoice?
If the Invoice doesn't exisist it notifys the user.

So how does the database know the folder name to use for each client?

You could store the path (with trailing backslash) in a text field for each
client. Then store the document name (pathless) in a text field with the
document. Use the Click (or DblClick) event of the text box to concatenate
the 2 values and FollowHyperlink to open the document.

The code you need to get the path for the client record is here:
http://www.mvps.org/access/api/api0002.htm

And you can then set the initial folder correctly, and get the file name
with this code:
http://www.mvps.org/access/api/api0001.htm

Using Text fields like that generally works better than using a Hyperlink
field.

I was hoping that one field would be the Client and another field would be
the invoice, the client # would specify a piticular folder on my server and
the invoice # would specify the invoice.pdf. I will check out your links and
see if they will do what I am needing to do.

Over time, one client may have more than one invoice.
You therefore need a table of clients, and a related table of invoices.

Because one invoice can contain multiple items, you probably need a related
table for the InvoiceDetails as well. For an example, open the Northwind
sample database, and see the Customer, Order and OrderDetail tables.
