I just need someone to review my VB code

This is the assignment:

Write a VB program that uses an Array of Strings to store state names as read in from the text file StatesBySize.txt.  I will make this file available for your use on our course Sakai web page (Under Resources / Assignments folder).   My suggestion:  On your C-Drive create a folder called VB2012 (its full name would be C:VB2012”.  We will put all data files used for this course into that folder.  If you do this then the call to ReadAllLines will refer to “C:VB2012StatesBySize.txt”

 

This is my code:

Public Class Form1

    Private Property From As Object

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        Dim States() As String = IO.File.ReadAllLines(“C:VB2012StatesBySize.txt”)

        For i As Integer = 0 To States.Count – 1

            lstbx1.Items.Add(States(i))

 

        Next

    End Sub

    Private Sub btn1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn1.Click
        Dim txtbx1 As Integer
        Dim txtbx2 As Integer
        Dim states() As String = IO.File.ReadAllLines(“C:VB2012StatesBySize.txt”)
        If Not Integer.TryParse(From.text, txtbx1) Or txtbx1 < 0 Or txtbx1 > 50 Then

            MessageBox.Show(“Please Input Valid Number For From:”, “Error (Shelina Lewis”)

            Return

 

        End If
        lstbx1.Items.Clear()
        For i As Integer = txtbx1 – 1 To txtbx2 – 1

            lstbx1.Items.Add(states(i))
        Next

 

    End Sub
End Class
