[RESOLVED] Help! Vb.net Reading a text file line by line

[.paul.]

here's how. on load it reads your text file into a string array, then displays the lines 1 by 1 as you click the button:

Public Class Form1
 
    Dim lines() As String
    Dim index As Integer = 0
 
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        lines = IO.File.ReadAllLines("filename.txt")
    End Sub
 
    Private Sub button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles button1.Click
        TextBox1.Text &= lines(index) & Environment.NewLine
        index += 1
        If index > lines.GetUpperBound(0) Then button1.Enabled = False
    End Sub
 
End Class
