Opening and closing default browser

[jramos]

Hi all,

I have a little problem with one application that i'm making.
I've a text file with lots of links to be opened in default browser. I read the file and open the links with a delay of 5 seconds between links.
My problem is that it will open a new link in a new tab of default browser, and i would like to use the same tab to open all links and when it finishes reading the links on text file close that tab.

My code is the following:

Private Sub OpenLinkBtn_Click(sender As Object, e As EventArgs) Handles OpenLinkBtn.Click
        Dim FicheiroIn As FileStream 
        Dim StreamLeitura As StreamReader 
        Dim LinhaIn As String                     
        Dim Nlinhas As Integer

        Nlinhas = 0
        FicheiroIn = New FileStream(SelectFileTxt.Text, FileMode.Open, FileAccess.Read, FileShare.Read)
        StreamLeitura = New StreamReader(FicheiroIn, System.Text.Encoding.Default)
        StreamLeitura.BaseStream.Seek(0, SeekOrigin.Begin)

        Do While StreamLeitura.Peek > -1
            LinhaIn = StreamLeitura.ReadLine
            Process.Start(LinhaIn)
            System.Threading.Thread.Sleep(5000)
            Nlinhas = Nlinhas + 1
        Loop
        MessageBox.Show(Convert.ToString(Nlinhas) + " Links Opened")

        StreamLeitura.Close()
        FicheiroIn.Close()
    End Sub

Thanks.
