Public Class Form1
    Dim int As Integer = 0
 
    Private Sub Loading(ByVal sender As Object, ByVal e As Windows.Forms.WebBrowserProgressChangedEventArgs)
        ToolStripProgressBar1.Maximum = e.MaximumProgress
        ToolStripProgressBar1.Value = e.CurrentProgress
    End Sub
 
    Private Sub Done(ByVal sender As Object, ByVal e As Windows.Forms.WebBrowserDocumentCompletedEventArgs)
        TabControl1.SelectedTab.Text = CType(TabControl1.SelectedTab.Controls.Item(0), WebBrowser).DocumentTitle
        ComboBox1.Text = CType(TabControl1.SelectedTab.Controls.Item(0), WebBrowser).Url.ToString
    End Sub
 
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim browser As New WebBrowser
        TabControl1.TabPages.Add("New Page")
        browser.Name = "Web Browser"
        browser.Dock = DockStyle.Fill
        TabControl1.SelectedTab.Controls.Add(browser)
        AddHandler browser.ProgressChanged, AddressOf Loading
        AddHandler browser.DocumentCompleted, AddressOf Done
        int = int + 1
        CType(TabControl1.SelectedTab.Controls.Item(0), WebBrowser).GoHome()
    End Sub
 
    Private Sub AddTabToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles AddTabToolStripMenuItem.Click
        Dim browser As New WebBrowser
        TabControl1.TabPages.Add("New Page")
        TabControl1.SelectTab(int)
        browser.Name = "Web Browser"
        browser.Dock = DockStyle.Fill
        TabControl1.SelectedTab.Controls.Add(browser)
        AddHandler browser.ProgressChanged, AddressOf Loading
        AddHandler browser.DocumentCompleted, AddressOf Done
        int = int + 1
        CType(TabControl1.SelectedTab.Controls.Item(0), WebBrowser).GoHome()
    End Sub
 
    Private Sub RemoveTabToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RemoveTabToolStripMenuItem.Click
        If Not TabControl1.TabPages.Count = 1 Then
            TabControl1.TabPages.RemoveAt(TabControl1.SelectedIndex)
            TabControl1.SelectTab(TabControl1.TabPages.Count - 1)
            int = int - 1
        End If
    End Sub
 
    Private Sub WebsitePropertiesToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles WebsitePropertiesToolStripMenuItem.Click
        CType(TabControl1.SelectedTab.Controls.Item(0), WebBrowser).ShowPropertiesDialog()
    End Sub
 
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        CType(TabControl1.SelectedTab.Controls.Item(0), WebBrowser).GoBack()
    End Sub
 
    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        CType(TabControl1.SelectedTab.Controls.Item(0), WebBrowser).GoForward()
    End Sub
 
    Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
        CType(TabControl1.SelectedTab.Controls.Item(0), WebBrowser).Refresh()
    End Sub
 
    Private Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click
        CType(TabControl1.SelectedTab.Controls.Item(0), WebBrowser).Stop()
    End Sub
 
    Private Sub Button5_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button5.Click
        CType(TabControl1.SelectedTab.Controls.Item(0), WebBrowser).GoHome()
    End Sub
 
    Private Sub Button6_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button6.Click
        CType(TabControl1.SelectedTab.Controls.Item(0), WebBrowser).Navigate(ComboBox1.Text)
    End Sub
 
    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
        ToolStripStatusLabel1.Text = CType(TabControl1.SelectedTab.Controls.Item(0), WebBrowser).StatusText
    End Sub
End Class

Just store the user's specified home page in a text file or use the My.Settings feature to save it, then when a new tab is opened or when your program is first launched then you read that file or use My.Settings to get the home page address. Then just call the Navigate method of your WebBrowser control and pass it the address.

so i would do something like this

vb.net Code:

CType(TabControl1.SelectedTab.Controls.Item(0), WebBrowser).Navigate(ComboBox1.Text)

get from homepage.txt?
