Hi,

I have come to ask about "System.IO.StreamReader.ReadLine"
I want it to read line 1, then 2, then 3, and it keeps going for 20

Please just give me the code to read line 5 for example, then i will do the rest, here is the code for you to work on

        Dim loadf As New System.IO.StreamReader("c:/text.txt")
        textbox5.Text = loadf.ReadLine()

Thats really all i know, please help

Thanks, Luke

to read from file line by line you need to use ReadLine method as you did , plus checking if you reached the end of file or not by Peek method

VB.NET Syntax (Toggle Plain Text) 
  1. While loadf.Peek <> -1
  2.             Line = loadf.ReadLine()
  3.            ...
  4.            ...
  5.         End While

i am not sure if I understand you, you want to write line 5 in the textbox? then in the while loop above check if you reached line 5 by counter then if yes show the line in textbox

VB.NET Syntax (Toggle Plain Text) 
  1. n = 0
  2.         While loadf.Peek <> -1
  3.             n = n + 1
  4.             Line = loadf.ReadLine()
  5.             If n = 5 Then
  6.                   TextBox1.Text = Line
  7.             End If
  8.  
  9.         End While
