Question Web Browser, issues with timestamps and favourites section

[MikeCorruption]

Hey guys, ive been given a project of a web browser to complete and ive built the whole web browser but there are two parts i just cannot seem to get working, i have tried many youtube guides and nothing, i am getting the same issues.

First here is the whole of my Web Browser code:

  Imports System.IOPublic Class Form1
    'Declaring i to be used as an integer
    Dim int As Integer = 0
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        'Declaring Browse, when Form loads this code will load a Web Browser inside a new tab.
        Dim Browser As New WebBrowser
        TabControl1.TabPages.Add("New Tab")
        TabControl1.SelectTab(1 - 1)
        Browser.Name = "webbrowser"
        Browser.Dock = DockStyle.Fill
        TabControl1.SelectedTab.Controls.Add(Browser)
        AddHandler Browser.DocumentCompleted, AddressOf Done
        int = int + 1
        CType(TabControl1.SelectedTab.Controls.Item(0), WebBrowser).Navigate(My.Settings.HomePage)
        recoverhistory()


        For Each item In My.Settings.Bookmark
            tsbURL.Items.Add(item)


        Next
    End Sub


    Private Sub TogglePanelToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TogglePanelToolStripMenuItem.Click
        'This code toggles the panel on/off
        togglePane()
    End Sub


    Sub togglePane()
        'Optional Code for a Button to show and hide panel
        ' bIndex = (bIndex + 1) Mod 2
        'btnShow.Text = status(bIndex)


        ' This collapses the Panel where the tabs for History, Favourites etc are kept.
        SplitContainer1.Panel1Collapsed = Not SplitContainer1.Panel1Collapsed
    End Sub




    Private Sub tsbAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tsbAdd.Click
        'This code means that a new tab will be added called "New Tab"
        Dim Browser As New WebBrowser
        TabControl1.TabPages.Add("New Tab" & int)
        TabControl1.SelectTab(int)

        'This IF statement will check if the there is more than 1 tab open, if yes then the code removes most recent tab from the tab control.
        If int > 1 Then
            TabControl1.TabPages.Remove(TabControl1.SelectedTab)
            TabControl1.SelectTab(TabControl1.TabPages.Count - 1)

        Next
    End Sub




    Private Sub ToolStripButton1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ToolStripButton1.Click
        'When this button is pressed the current URL in the URL box will be now the Home Page.

    End Sub
    Private Sub savehistory()
        'This code saves the history in a text format on the C Drive.
        Using w As StreamWriter = New StreamWriter("C:\mike")
            Dim i As Integer
            For i = 0 To lbHistory.Items.Count - 1
                w.WriteLine(lbHistory.Items.Item(i))

    End Sub

        Dim myHistory() As String


        Using r As StreamReader = New StreamReader("C:\\mike.txt")
            myHistory = r.ReadToEnd.Split(vbNewLine)
        End Using
        Dim i As Integer

    Private Sub savehistory()        'This code saves the history in a text format on the C Drive.

            Dim i As Integer

            myHistory = r.ReadToEnd.Split(vbNewLine)
        End Using
        Dim i As Integer
        For i = 0 To myHistory.Length - 1
            lbHistory.Items.Add(myHistory(i))
        Next
    End Sub

That part of the code is meant to allow the "History" to load after the browser is closed and reopened and it doesnt, one last problem, i cant seem to get any time stamps next to it.


Sorry if that is a lot, it is just really frustrating that i cant seem to get three elements working, any help even for one element would help me greatly

You might try using the same path for reading and writing the file to start with. I'm nor sure exactly what that second path, which isn't really a valid path, will do. This is a perfect example of why you should assign values like that to a field in one place only and then use that field in multiple places. That guarantees that you'll use the same value in all places.

Beyond that, please don't just say that code doesn't work. Explain what actually happens. If there's an exception then give us the error message. Otherwise, tell us where expectation differs from reality.
