What is the difference between VB6 and VB.net ?

The biggest difference is VB.Net supports multi-threading which can make a big difference in performance depending what OS and type (single user application compared to a NT-based service) of program you're making.

VB.Net has far better error handling.

More stuff built in for easier creation of Internet based applications.

No more retarded "set" keywords
a la, Dim objcls as class1
becomes, onjcls = new class1

Lots more differences exist, those four are some of the bigger ones and all good reasons to not use VB6, ever.
