best reference/guide for learning VBA

I learned a bit of VBA modifying recorded macroes but I now want to become a real VBA expert (with Excel 2010).

What are the best compact / regular / complete guides for learning VBA on the net?

I mean something like these:
http://www.excel-spreadsheet.com/vba/vba.htm
http://www.itu.dk/people/slauesen/UID/VBAcard2.pdf

Is there an official complete reference source done by Microsoft?
