If you want a dynamic solution, ASP.NET and SQL Server; only way to go.
Else, download the file and import it into Access. Perhaps Access 2010 will
permit you to dynamically query web sites; I don't know for sure because I
haven't used it yet.
I don't know for sure if this version of Access will do what you want, but I
know it is much more web-friendly than 2007, and anything prior to that, for
sure. I'm going to download this new version of Office when i get home
tonight. Then I'll have a better feel for the app.
For a credit cards? not that I am aware of. For web services in general?
the already proposed link gave at least one (unless it is now closed, which
is part of the problem, with web services).
