PowerTCP Sockets for .NET: Did You Know?

Did You Know?

That all the data sent and received between the client and the server is visible in a Trace event?
That every connection to the Server component is on a separate thread?
That the Tcp component can easily read data from a server until a delimiter is found?
That the Ping component can not only use the standard ICMP protocol for pinging other computers, but also TCP and UDP?

That all the data sent and received between the client and the server is visible in a Trace event?

The Trace event is a handy tool for debugging applications. It will fire whenever the component sends or receives data, and is perfect for adding logging capabilities to your application.

Code Sample:

private void myComponent_Trace(object sender, SegmentEventArgs e) 
{ 
    // Append data to a file
    System.IO.FileStream file = new System.IO.FileStream("c:\\Test\\log.txt", System.IO.FileMode.Append); 
    file.Write(e.Segment.Buffer, 0, e.Segment.Count); 
    file.Close(); 
}

That every connection to the Server component is on a separate thread?

Each connection is handled by a Tcp object executing on its own thread, allowing the construction of truly multi-threaded server applications.

Code Sample:

private void button1_Click(object sender, System.EventArgs e)
{
    //When the button is pressed
    //Start starts listening on port 7 (default for an echo server)
    server1.Listen(7);
}

private void server1_Connection(object sender, ConnectionEventArgs e)
{
    //Execution of a very simple echo server
    //This loop is performed on its own worker thread, 
    //so the server can handle many connections
    Segment receivedData = e.Tcp.Receive();
    while (e.Tcp.Connected)
    {
        e.Tcp.Send(receivedData.ToString());
        receivedData = e.Tcp.Receive();
    }
}

That the Tcp component can easily read data from a server until a delimiter is found?

An enhanced Tcp.Stream object is exposed on the component, providing higher level streaming capabilities such as searching for a delimiter.

Code Sample:

//Connect to a POP server, and examine its greeting message
tcp1.Connect("mail", 110); //POP servers use port 110
tcp1.ReceiveTimeout = 10000;

//Read the first 1024 bytes returned, stopping when a CRLF is found
//The Tcp.Stream property provides this capability
bool found = false;
string greeting = tcp1.Stream.Read("\r\n", 1024, ref found);
tcp1.Close();
			
if (found == true)
    MessageBox.Show(greeting);
else
    MessageBox.Show("No greeting was found");

That the Ping component can not only use the standard ICMP protocol for pinging other computers, but also TCP and UDP?

By simply setting the PingType property, a ping can be tried using ICMP, TCP, or UDP.

Code Sample:

//Try pinging a site using Tcp protocol
ping1.PingType = PingType.TCP;
EchoResult result = ping1.Send("www.dart.com");
MessageBox.Show(result.ToString());
