@ paul you might want to check if the form actually contains a label of that name just in case. Also, using/endusing for streamreaders are a lot easier

vb Code:
  1. Using sRead As New IO.StreamReader("D:\Users\Arben\Desktop\SerieA.txt")
  2.       Dim thisLine as string = ""
  3.       Dim nLabel as Integer = 0
  4.       Do Until sRead.EndOfStream
  5.           thisLine = sRead.ReadLine
  6.           if Me.Controls.ContainsKey("Label" & nLabel) then
  7.                Me.Controls("Label" & nLabel).Text = thisLine
  8.           End if
  9.           nLabel += 1
  10.        Loop
  11. End using
