Форма управления Cmd VB.NET

---

запустите сеанс cmd в форме windows с помощью команды " ipconfig"
но покажите ошибку на FnctionStartConsoleEvent
кто-нибудь мне поможет?

Что я уже пробовал:

Dim cdd() As String
    Event Avvia()
    Function FnctionStartConsoleEvent(e As KeyEventArgs) As EventHandler(Of ComboBox.ObjectCollection)
        If e.KeyData = Keys.Enter Then
            Dim process As Process = New Process
            With process
                '  .StartInfo.ErrorDialog = False
                .StartInfo.RedirectStandardInput = True
                .StartInfo.RedirectStandardOutput = True
                .StartInfo.UseShellExecute = False
                .StartInfo.FileName = "cmd.exe"
                .StartInfo.CreateNoWindow = True
                .StartInfo.WindowStyle = ProcessWindowStyle.Hidden
            End With
            process.Start()
            Try
                process.StandardInput.WriteLine("cd/d " & cdd(3))
            Catch
            End Try
            process.StandardInput.WriteLine(ComboBox1.Text)
            process.StandardInput.WriteLine("echo [~cd~]%cd%[~cd~]")
            process.StandardInput.WriteLine("exit")
            Dim outpp As New TextBox
            outpp.Text = process.StandardOutput.ReadToEnd
            cdd = Split(outpp.Text, "[~cd~]")

            For i = 4 To outpp.Lines.Length - 6
                RichTextBox1.Text = RichTextBox1.Text & outpp.Lines(i).Substring(0) & vbCrLf
            Next
            ComboBox1.Items.Add(ComboBox1.Text)
            ComboBox1.Text = ""
            RichTextBox1.SelectionStart = RichTextBox1.Text.Length
            RichTextBox1.ScrollToCaret()
        End If
    End Function

    Private Sub ComboBox1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles ComboBox1.SelectedIndexChanged
        AddHandler Avvia, AddressOf FnctionStartConsoleEvent
        If ComboBox1.SelectedText = "ipconfig" Then
            RaiseEvent Avvia()
        End If
    End Sub
