How can I automate Outlook and Word by using Visual C# .NET to create a e-mail message?

As the title may indicate, I'm trying to get one of my applications to be able to send an email.  I found an article from Microsoft that seemed to solve the problem:

http://support.microsoft.com/default.aspx?id=819398

The problem is that this article is targeted at Word 2002/2003, and I have word 2007.  I assumed that this wouldn't be a big deal, and that the same code should work for Word 2007.  It appears I was wrong.  When I attempted to use the code described I got a COMException was unhandled error ("Command Failed") on the line:

Document doc = wApp.Documents.Add(
                        ref template,
                        ref newTemplate,
                        ref documentType,
                        ref visible);

How can I fix this error, or more generally, how can I send an email from a Visual Studio project (using Outlook)?
