Hi there, use readLine method of a StreamReader.

        Dim StreamRd As FileStream
        'Check if the file is there.
        If File.Exists("C:\Data.txt") Then
            StreamRd = New FileStream("C:\Data.txt", FileMode.Open, FileAccess.Read)
        Else
            MsgBox("OOPS!! CEIP_Upload.txt not found")
            Exit Sub
        End If
        'Create reader and read from the file
        Dim FileReader As New StreamReader(StreamRd)
        TextBox1.Text = FileReader.ReadLine 'Show the first Line in a text box.
        'Read twice and you are in the 3rd line
        FileReader.Close()

oRead = oFile.OpenText(“C:\sample.txt”)
dim count = 1

 While oRead.Peek <> -1      
   if count = 3 then
      LineIn = oRead.ReadLine()
   end if
   count = count + 1
 End While

 oRead.Close()
