Write A Small Program For ITunes Using Windows COM?

I are trying to write a small program for iTunes using Windows COM. We are able to talk to iTunes and create popup boxes that show the current track, and a few other small things. However, when we try to set this info to a Label for example, we get:

InvalidOperationException was unhandled by user code Cross-thread operation not valid: Control 'Label1' accessed from a thread other than the thread it was created on.

The program then hangs and locks iTunes from closing. I believe the issue is the event handler I have created, which I know very little about. We are using VB 2010, so that may change some things. We followed a rough example from a forum post HERE. If you scroll down the orange text, you will see a reply right after by Will Hughes with a "Handles iTunes.OnPlayEvent". If I add this to the end of my event handler, I get:

Handles clause requires a WithEvents variable defined in the containing type or one of its base types. Not sure if its important to the issue or not, but I found it curious. Our code is shown below.

Imports iTunesLib
Public Class Form1
Private iTunes As New iTunesApp
