I have a text file that contains this info:

VB

ASKK90001BRANCH
COMPANY-HONDAHCMI
01
HCAISD-02

i tried using this code:

VB

Dim objReader As New System.IO.StreamReader(Application.StartupPath & "\SQ.txt")
LBLcounter.Text = objReader.ReadToEnd
objReader.Close()

but it reads everything and when i change 'ReadToEnd' to 'ReadLine', it only reads the first.

how do I read the 3rd line of the text? the '01'?

Solution 2

I found out a very easy way.

VB

Dim Counter As String = System.IO.File.ReadAllLines(Application.StartupPath& "\SQ.txt")(2)
LBLcounter.text = Counter

the (2) is the number of the line of the text.
