I use these commands to open and read a text file

Imports System
Imports System.IO
Imports System.Text

...

Dim temp As UTF8Encoding = New UTF8Encoding(True)
Dim fs As FileStream
Dim openFileDialog1 As New OpenFileDialog
openFileDialog1.Filter = "Archivos de texto (*.txt)|*.txt|Todos los archivos|*.*"

If openFileDialog1.ShowDialog() = DialogResult.OK Then
   archivo = openFileDialog1.FileName
   If File.Exists(openFileDialog1.FileName) Then
       Me.lblProcesando.Visible = True
       fs = File.Open(archivo, FileMode.Open, FileAccess.Read)
       Do While fs.Read(linea, 0, linea.Length) > 0
           sLinea = temp.GetString(linea)
           txtJob = sLinea.Substring(0, 8)
           txtStockCode = sLinea.Substring(8, 30)
           txtWarehouse = sLinea.Substring(38, 2)
           txtQtyReqd = sLinea.Substring(40, 14)
       Loop
       fs.Close()
       ....
       ....
    end if
end if
