What is the best method to learn the VGA programming language?

This is like asking what's the best method to learn how to write prose. All
the VBA-specific books are at best like grammar texts with a few examples.
The really good programming books don't deal with VBA.

If you know any programming languages, you could get about as much useful
information from John Green's or John Walkenbach's Excel VBA books. If you
don't know any programming languages, you should start with a good general
programming text, probably one for Visual Basic. Search Amazon and read the
reader comments.
