A while back I talked about Bringing new life to your VB6 apps with the Interop Forms Toolkit and now they have shipped Version 2.0... If you have a VB6 app and you are looking to take incremental advantage of .NET, you should check this out.
Here is a cool example project where they leverage the WinForms MenuStrip and ToolStrip in a VB6 application! Very cool.. I can't wait to see what you do with it!
