Dim isMainUrl As Boolean
 
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        isMainUrl = True
        WebBrowser1.Navigate("http://www.google.com/")        '' or whatever 
    End Sub
 
    Private Sub WebBrowser1_DocumentCompleted(ByVal sender As System.Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted
        If WebBrowser1.ReadyState = WebBrowserReadyState.Complete Then
            If isMainUrl Then
                isMainUrl = False
                WebBrowser1.Navigate(WebBrowser1.Url.AbsoluteUri & TextBox1.Text)
            End If
        End If
    End Sub
