Problem


I like to develope a little browser. I can access a site, I can also go to the last page I visited, but I have problems to access the next page button after I clicked on the "last page" button. (Example: You visit Google.com, then Machiavelliiscool.com and then mymotherissometimessilly.com. You wanna get back to Machaivelliiscool.com with clicking the last Page Button, but if I like to go back to the mymotherissometimessilly.com webpage I have to click on the next side button). And the next side button isn't working.


Codes


a) MainForm

Public Class Form1
    Public i As Integer = 1
    Dim j As Integer = 1
    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Einstellungen.lstChronik.Items.Add(txtAdresse.Text)
        wb.Navigate(txtAdresse.Text)
    End Sub

    Private Sub cmdEinstellungen_Click(sender As Object, e As EventArgs) Handles cmdEinstellungen.Click
        Einstellungen.ShowDialog()
    End Sub

    Private Sub cmdRückwärts_Click(sender As Object, e As EventArgs) Handles cmdRückwärts.Click
        i = i + 1
        Try
            cmdVorwärts.Visible = True
            wb.Navigate(Einstellungen.lstChronik.Items(Einstellungen.lstChronik.Items.Count - i))
        Catch ex As Exception
        End Try
    End Sub

    Private Sub Button3_Click(sender As Object, e As EventArgs) Handles cmdVorwärts.Click
        wb.Navigate(Einstellungen.lstChronik.Items(Einstellungen.lstChronik.Items.Count - i + j))
    End Sub
End Class

Setting.vb (Windows Form):

<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _
Partial Class Einstellungen
    Inherits System.Windows.Forms.Form

    'Das Formular überschreibt den Löschvorgang, um die Komponentenliste zu bereinigen.
    <System.Diagnostics.DebuggerNonUserCode()> _
    Protected Overrides Sub Dispose(ByVal disposing As Boolean)
        Try
            If disposing AndAlso components IsNot Nothing Then
                components.Dispose()
            End If
        Finally
            MyBase.Dispose(disposing)
