Hi
There are many books in the marker for
VB 6.0. I would personally suggest, Visual Basic 6.0 Reference from Microsoft Press ... this is a good one
Let me also tell you that VB6.0 is a 'old-fashioned' programming language - it is easy to learn, but nowadays projects are done using
VB.NET
If you are new to programming you can directly start with
VB.NET - Wrox has good number of books on it
Cheers
