Just wanted to point out that if you put:

OPTION STRICT ON

at the top of your VB code, the background compiler will hilight anywhere you didn't declare variables (and lots of other optimizations) so that you can find these things while editing...

>SB.Append("Hi"+i.ToString());
>SB.Append(" blah blahblah blahblah blahblah blahblah blahblah blah ");

>As I´m not a VBer, and I´m just starting study C#, I don´t know if that´s the correct way of doing things... anyway, for what people are saying, such code must have similar performance... but, that wasn´t what I saw.
