    Hi Reshma,

     


    I think that the reason of the error is because socket was not closed.

     

    If your test failed and terminated before the socket was closed, you must either reopen test project or restart TestComplete (don't remember exactly, check what will work for you).

    Hi Reshma,


     


    As far as I understand, you've posted the ready example here.


    Were you able to resolve the error? Please share with us what was the reason for it.

    What you siad might be true, Testcomplete got struck while executing the script and crashed. May be the socket didn't get closed. Tried either ways but not able to fix the issue.

    Only one usage of each socket address (protocol/network address/port) is normally permitted


    TcpListener listerner = new TcpListener(44444);



    TcpClient client;



    String message="";



    Object tts;



    Socket m_clientSocket;





    protected void Page_Load(object sender, EventArgs e)



    {



    if (Page.IsPostBack == false)



    {



    listerner.Start();



    Timer1.Enabled = true;



    TextBox4.Enabled = false;



    }



    }



    protected void Button1_Click(object sender, EventArgs e)



    {



    try



    {



    if (TextBox1.Text == "" | TextBox2.Text == "" | TextBox3.Text == "")



    {



    Label1.Text = "Sorry Uncomplete data";



    }



    else



    {



    client = new TcpClient(TextBox2.Text, 44444);



    StreamWriter writer = new StreamWriter(client.GetStream());



    writer.Write(TextBox1.Text + " says:" + TextBox3.Text);



    writer.Flush();



    TextBox3.Text = "";



    }



    }



    catch (Exception ex)



    {



    listerner.Stop();



    }



    }



    protected void Timer1_Tick(object sender, EventArgs e)



    {



    try



    {



    if (listerner.Pending())



    {



    message = "";



    client = listerner.AcceptTcpClient();



    StreamReader reader = new StreamReader(client.GetStream());



    while (reader.Peek() > -1)



    {



    message = message + Convert.ToChar(reader.Read()).ToString();



    }



    this.Focus();



    TextBox4.Text = (TextBox4.Text + message + "\n");



    SpVoice s = new SpVoice();



    s.Speak(message);



    }



    }



    catch



    {



    listerner.Stop();



     



    }



    }
