2 Questions about DUN

My first question is. is this possible to add new Dial-up profile using vb.net? And make that as default dialup
with this strings..

Connection Name: Any Profile Name
Dial #: *99***1#

2nd question is:

I tried to code to dial my DUN using .net.
But How can I dial that without prompting me the dial window.

Here is my code.

Code:

---

    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        Dim DResult As Int32

        DResult = InternetDial(Me.Handle, "Profile Name", DialUpOptions.INTERNET_DIAL_UNATTENDED, mlConnection, 0)

        If (DResult = ERROR_SUCCESS) Then
            MessageBox.Show("Dial Up Successful", "Dial-Up Connection")
        Else
            MessageBox.Show("UnSuccessFull Error Code" & DResult, "Dial-Up Connection")
        End If
    End Sub

---

That code display only the dial window and not automatically dial a connection.
