I am sorry I was trying to reply to another post.  This has to do with Exceptions when running the Battle Tank part II.

Here is the error:
System.TypeInitializationException was unhandled
  Message="The type initializer for 'Microsoft.DirectX.Direct3D.Manager' threw an exception."

When I was adding the wrong DirectX reference to the project I had duplicate function names and this I think is the root cause of the problem.  I had the IDE VS2005 resolve the conflict by adding an app.config file to the project with the resolve conflict wizard.  To fix the problem change the reference back to the Microsoft.DirectX version 1.0.2902.0 and remove the app.config file from your project.
