where is the best reference on the net?

where can I find the best vb reference on the web?
bacause I don't have my book with me these days, and I will need to know many objects or properties, function ......

if I can find a good reference.....

and where can I search for error code, and what's causing it, and how to solve the problem? on the net(except here.I know this site is great, because you guys are here)

thanks.

Cerebrate

MSDN Online of course.

Well i say that, but it is hardly the best ref. Though obviously it has all of the propeties etc, and you can look up error codes.
