anyone knows a good book on design patterns, specificaly for VB6

I am assuming you want a book that concentrates more on implemenation that
patterns themselves. To learn about patterns you really need to go directly
to the source "Design Patterns", Gamma (Gang of Four) and "Object Models",
Fowler.

One useful book is "Microsoft Visual Basic Design Patterns" by William
Stamatakis. It is useful because it emphasises COM. Most of the OOPL
limitations in VB are related to the limitations of COM and not VB. (VB's
object model is COM based).

This book will not be an ultimate source. You must consider that patterns by
design are devoid of implementation. (Pun intended. <g>) You will discover
that there are often many ways to skin the poor proverbial cat. While
suggested implementations of various patterns may appear to translate easily
into full OOPLs such as C++. The suggestions, like those in this book, are
just one of many possible solutions.

Someone, somewhere, always manages to come up with something a little better
for a specific problem domain. You will want to supplement your
pattern-knowledge with articles on the net.
