I want to buy a book or two on VB, but I want your suggestions first.

I have been developping with VFP for over 9 years and have worked with VB 5 for 6 months 2 years ago, so I'm not a complete beginner.

What I'm looking for is a reference book where I can refer when I want to know how things are done with VB (connecting to database, creating classes, etc.) and that can teach me how to create a 3-tiers application using COM.

My guess is that I will need two differents books, one as a general reference and one for 3-tiers development, but I'm looking for your suggestions.

TIA
