Necessary Components and Setup

The items you will read about in this article came about as a result of some project work that I’ve been doing for the Indianapolis Colts. I’ve been helping to lead efforts to build and launch, a social networking site for Colts fans. I got in to a discussion at the Microsoft MVP summit around the idea of a mashup, which is about using multiple online services to create a new one; that inspired me to play around with Virtual Earth.

The webpart display in the example relies on the native functionality contained within ASP.NET. For the purposes of this article, I’m not going to go in to all of the background setup that took place to get the web site set up to display webparts. Rather, I’m going to assume that the readership already has a site setup that will display a webpart. Worst case, you could just as easily toss the webpart portion and put the code in a page instead.

Figure 1: Webpart Display with Map


This month’s column covered how to build a webpart to display a map produced from Microsoft Virtual Earth. It used an HttpHandler to produce the RSS feed format to drive Virtual Earth. It can appear daunting at first, but hopefully, as you’ve seen, it is pretty straightforward when you break down the individual parts of the solution.
