Building a Visualization
You can build a custom visualization by using Visual Studio along with the Windows Media Player plug-in wizard. For information on setting up the wizard and building a plug-in, see Building a Plug-in.
When you run the wizard, you will be given a choice of several different types of plug-ins. Choose Visualization.
After you complete the wizard and build your plug-in, start a song in Windows Media Player and click through the visualizations. The presets that are automatically built for you are called projectname Bars and projectname Wave, where projectname is the name of your project.
