Visual Basic .NET 2003 Language Changes

Although I'll be the
first to suggest it should have been up earlier, I wrote a short article about
the new VB.NET 2003 language features... and it is up on MSDN now.

  Duncan, thanks for the article on language changes. I'm curious about the scope of loop control variables. Given this pseudocode:
  <PRE class=code>Dim counter As Integer
  For i as Integer = 0 To 10
  For j as Integer = 0 to 10
  Console.WriteLine(i*j)
  Next
  Next
  </PRE>
  will it produce an error? I assume not since the inner loop should be able to access the variable since it's still in the scope of the outer loop. And I would assume that after the inner loop is complete, referencing j would give an error. Would I be correct?

  Glen...
  
  Yep, you are correct... the inner loop is still within the scope of the outer, so the i variable is valid within the inner loop, but j is not available outside of the inner loop....
  
  hope that is clearer than it seems when I read it...
