Have you ever played with asp.net? You can download a portal http://www.asp.net/Default.aspx?tabindex=8&tabid=47 and install it. It's changed a bit over the years, then take a look at the document module. All the code and sql is there for you to look and learn. It's all .NET in C# or VB. With little effort it will port to a windows application. If your using VB6.... well you don't want to go that route. Here's a link to the visual basic 2005 beta http://lab.msdn.microsoft.com/express/vbasic/ in case you don't have any .NET software.
