Hello,

I have 6 devices, price checkers. I have a project which the client in a supermarket will scan a product on this device and it will return the price of the product. I have managed to connect with one device, get the bar code and send data. But I can not seem to do to connect with multiple socket connection.
This is the code when I receive and send data:

Connecting with the device:

private void connect1(string adip, int porta)
        {
            try
            {
                IPEndPoint ip = new IPEndPoint(IPAddress.Parse(adip), porta);
                connect1 = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
                connect1.Connect(ip);
            }
            catch (System.Net.Sockets.SocketException se)
            {
                MessageBox.Show(se.Message);
            }
        }

Getting the barcode:

private void getbarCode()
        {
            byte[] data = new byte[1024];
            int receivedDataLength = lidhje.Receive(data);
            numberCodeBar = Encoding.ASCII.GetString(data, 0, receivedDataLength);
        }

Sending data to device:

private void sendData(string price1)
        {
            try
            {
                Object objData = price1;
                byte[] price = System.Text.Encoding.ASCII.GetBytes(objData.ToString());

                connect1.Send(price);
            }
            catch (System.Net.Sockets.SocketException se)
            {
                MessageBox.Show(se.Message);
            }
        }

I want to make this with muliple decives in the same time. I have searched Google but no luck.
