How do I use schemas on my desktop?

[mgoold2002]

Hello. I'm new to using XML/HTML. I am trying to learn to validate
xml sample docs against schemas. I have an XML and Schema file (.xsd)
saved to my desktop. Below is my sample code, which is borrowed from
the .NET help files. It blows up when I try to refererence a schema
that is on my desktop.

If you can, please correct my misunderstandin g about referencing
schemas, as evidenced in the below example. Am I attempting the
impossible, or just attempting the possible wrongly?

Thanks for any help,
