I recently found myself searching (to no avail) for information on how the SharePoint list attachment process actually works; it seemed as if there was no documentation or previous experiences available anywhere. In my particular scenario, I needed to be able to produce an auditable list which showed the date/time, filename, and username for every upload, a report which WSS doesn’t offer out of the box.

I have decided to include step by step instructions on building a solution that queries an XML web service for data and displays that information in SharePoint 2007.
