  Dim TeamAScoreCollection As New Collection

  Dim TeamBScoreCollection As New Collection

  Dim objtextbox As New Textbox

  'set scores in all Team A textboxes to 0

  For each objtextbox in TeamAScoreCollection

  objtextbox.Text="0"

  Next objtextbox

  'set scores in all Team B textboxes to 0

  For each objtextbox in TeamBScoreCollection

  objtextbox.Text="0"

  Next objtextbox

  By this code I have 2 collection variables that control a bunch of textboxes. Now rather than write 2 separate For Each loops, to write 0 in all the textboxes,  how can I do it in ONE loop?

  I have tried using the operators like And but apparently you cant do that. Any suggestions?

  Why do you need a single loop?  The only way to do it using a for each loop would be to create a 3rd collection which combines the 2 you already have.  Then iterate through that collection.  If your collections are the same size you could use a regular for loop.

          For i As Integer = 0 To TeamAScoreCollection.Count - 1
              DirectCast(TeamAScoreCollection.Item(i), TextBox).Text = "0"
              DirectCast(TeamBScoreCollection.Item(i), TextBox).Text = "0"
          Next i

  Also, if your using VS2005 you should use a list instead of a general collection. You can create a list of textboxes like this.

  Dim TeamAScoreCollection As List(Of TextBox)

  I am currently using VS2003. My Collections each have 14 textboxes.

  The only reason why I had a For Each loop was because that was the first thing that popped into my head to make it work....

  How can I make it work with the For Loop?
