For Each, Sql Result Set

Hi All,

I need to For Each loop tied back to a SQL result set.  This is what I have so far, I know its not much but I'm stuck. 

Thanks soooo much!

Dim conn As SqlConnection
Dim comm As SqlCommand
Dim reader As SqlDataReader
Dim connectionstring As String = ConfigurationManager.ConnectionStrings("Magic").ConnectionString
conn = New SqlConnection(connectionstring)
comm = New SqlCommand("Select Distinct([_Group_]) from _Smdba_._Groupdet_ Where [_InActive_:] = 0", conn)

Try
conn.Open()
reader = comm.ExecuteReader()

   For Each (FOR EACH SQL RECORD)
      'I'm going to put some code in here....
   reader.Close()
Catch
   dberrorlabel.Text = "Error Loading Admin Panel"
Finally
   conn.Close()
End Try
