Lots of programmers here, so thought I'd ask - can anyone recommend any decent books on VBA? It'd be most useful/valuable for my work, and would like to start learning it in my spare time.

I'm not a complete idiot at VBA, so can probably forget the "Dummies Guide" books, but nonetheless need something that teaches/explains the principles whilst also being a decent reference guide.

Obviously there are user reviews on Amazon, but every book seems to have at least one review saying it's shit, and another source of feedback never hurts.

Thanks in advance.
