You'll be unlikely to find any VB6 specific stuff these days - it's been superseded for a very long time!
I'd suggest that you look at learning C#: modern VB uses the same .NET framework, and looks so similar to VB6 that you'll fall into bad habits that aren't compatible with "modern" paradigms. C# is easy enough and there are plenty of learning resources available for it. Like VB, it's a part of Visual Studio, which is available free from Microsoft in the Community Edition.
Good luck - and welcome back!
