So what is it?

Anyone can tell me what Visual Basic .NET is?? is it a programming language like PHP???

Yes it's a programming language but not like PHP.
VB.Net is the next version of Visual Basic.
It's different from VB6 though since it has been rewritten from the ground up and isn't really backward compatible.

Thanks

So if you know how to use vb6 would you be able to use .net? How different are they eg nothing in common, virtually same etc?

it should be pretty easy to pick up VB.net if you know VB.

The syntax is almost identical, it's just figuring out where all the functionality derives from that takes some time.
