Calling Web Services from "pre-.NET" Applications

Here's are three articles that talk about developing and using Web Services for "pre-.NET" applications (e.g. a VB6 app or MFC COM control). Thanks to Brian Combs from PSS for forwarding to me:

1. Integrating Web Services and COM Components using the SOAP Toolkit - Article

2. Migrating from the Microsoft SOAP Toolkit to the .NET Framework - Article

3. Calling .NET Assemblies and Web Services from VB6 - Article
