For links to webpages dealing with VB / C / C++ interoperability (including getting at the Win32 API and how to pass function pointers) see
Things I know I'm going to need one day
- Control Arrays in VB.Net - from visualbasic.about.com
- A VB.NET class for basic linear algebra - good stuff with links and comments
- VB.NET and C# Comparison table
Generally useful sites - these come up over and over in any search for VB stuff
- Visual Basic Resource Channel (Experts Exchange)
- Matt Reynold's .NET 247
