Populating listview from combo box

I have a program where I am trying to select a combobox entry and populate into the listview. However I can only get one of the combo box entries to show(which is the last). I am having a problem storing each individual record from a text file. Can someone show me someideas on how to do this?

Imports System.IO
Public Class Form1
    Private BooksStreamReader As StreamReader
    Dim str(51) As String
    Structure Book
        Dim ISBN As String
        Dim Title1 As String
        Dim Author As String
        Dim Publisher As String
        Dim Subject_Code As String
        Dim Shelf_Location As String
        Dim Fiction As Boolean
        Dim Price As Decimal
        Dim QDH As Integer

    End Structure
    Dim ISBN As String
    Dim Title1 As String
    Dim Author As String
    Dim Publisher As String
    Dim Subject_Code As String
    Dim Shelf_Location As String
    Dim Fiction As Boolean
    Dim Price As Decimal
    Dim QDH As Integer
    Dim BooksArray(50) As Book
    Dim BookUBound As Integer
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim I As Integer = 0
        Try
            BooksStreamReader = New StreamReader("C:\Users\Public\Pictures\Books2.Txt")

        Catch ex As Exception
            MessageBox.Show("File Not Found")

        End Try


        'Display combobox ISBNS
        Do While BooksStreamReader.Peek <> -1

            ISBN = BooksStreamReader.ReadLine()
            Title1 = BooksStreamReader.ReadLine()
            Author = BooksStreamReader.ReadLine()
            Publisher = BooksStreamReader.ReadLine()
            Subject_Code = BooksStreamReader.ReadLine()
            Shelf_Location = BooksStreamReader.ReadLine()
            Fiction = BooksStreamReader.ReadLine()
            Price = BooksStreamReader.ReadLine()
            QDH = BooksStreamReader.ReadLine()
            ComboBox1.Items.Add(ISBN)

        Loop
        BookUBound = BooksArray.Length - 1


    End Sub
    Private Sub DisplayRecord()


    End Sub

    Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged
        Form1_Load(sender, e)
        Dim str(200) As String
        Dim selectedindex As Integer = 0

            str(0) = ISBN
            str(1) = Title1
            str(2)开发者_StackOverflow中文版 = Author
            str(3) = Fiction
            str(4) = Price
            str(5) = QDH
            str(6) = QDH * Price



        If CheckBox1.Checked Then

            Dim itm As New ListViewItem(str)
            ListView1.Items.Add(itm)
        End If


    End Sub
End Class

This is rather a train wreck, you are really not close. Suggested fixes:

Structure Book
    Dim ISBN As String
    '' etc
    Public Overrides Function ToString() As String
        Return ISBN
    End Function
End Structure

...
Do While BooksStreamReader.Peek <> -1
    Dim book As New Book
    book.ISBN = BooksStreamReader.ReadLine()
    '' etc
    ComboBox1.Items.Add(book)
Loop
...

Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged
    If CheckBox1.Checked Then
        Dim book As Book = CType(ComboBox1.SelectedItem, Book)
        Dim item As New ListViewItem(book.ISBN)
        item.SubItems.Add(book.Title)
        '' etc...
        ListView1.Items.Add(item)
    End If
End Sub
