I had powertcp version 1.1, I decided to upgrade, so I purchased version 4.4,
now I got a lot of errors, syntax errors, everywhere of the project, please help to know how the objects changed from 1.1 to 4.4,

here are some errors which I got in my project:

    private void udp1_EndReceive(object sender, Dart.PowerTCP.Sockets.DatagramEventArgs e)
      string msg = e.Datagram.ToString();
      LEAMRALogger.Logger.WriteByDate("Logs", "INFO", "udp1_EndReceive", "udp1_EndReceive Function: " + msg);

      tcp1.Connect("", TCPPort);

private Dart.PowerTCP.Sockets.Tcp tcp1;
    private Dart.PowerTCP.Sockets.Udp udp1;
    private Dart.PowerTCP.Sockets.Server server1;
    private System.Diagnostics.EventLog eventLog1;

private void InitializeComponent()
      this.components = new System.ComponentModel.Container();
      this.tcp1 = new Dart.PowerTCP.Sockets.Tcp(this.components);
      this.udp1 = new Dart.PowerTCP.Sockets.Udp(this.components);
      this.server1 = new Dart.PowerTCP.Sockets.Server(this.components);
      this.eventLog1 = new System.Diagnostics.EventLog();
      // tcp1
      this.tcp1.Charset = "windows-1256";
      // udp1
      this.udp1.Charset = "windows-1256";
      this.udp1.Editor = this.udp1;
      this.udp1.EndReceive += new Dart.PowerTCP.Sockets.Da

The control was redesigned, so I am unable to just provide a 1:1 conversion guide here, but to get you started:

tcp1.Connect("", TCPPort); = tcp1.Connect(new TcpSession(new IPEndPoint("", TCPPort);

tcp1.Send(msg); = tcp1.Write(msg);

BeginReceive (and EndReceive) has been removed. Call Udp.Receive on a worker thread:

udp1.Start(UdpReceive, null);

private void UdpReceive(object state)
   byte[] buffer = new byte[1024];

And use udp1.Marshal (with the Udp UserState event wired up) to transfer data back to the UI thread. Alternatively, use Udp.ReceiveAsync().

Server now creates a new IO completion thread for each new client:

Server.Listen(Convert.ToInt32(TCPPort)); = server1.Start(server1_NewConnection, TCPPort, null);

private void server1_NewConnection(Tcp tcp, object state)
(replaces server1_Connection)

If you have any further specific questions, please let me know. I would recommend examining our included Server sample for a demonstration of using the server component (and TCP and UDP client samples for demonstrations of their use).

  I have a VB project that is using powertcp version 1.1 and need to convert to version 4.4.
I have used BeginReceive and EndReceive to receive data from host. Below is the section of the code:

Imports Dart.PowerTcp.Telnet

Public Class TelnetComm
 Implements IComm

  Private WithEvents mobjTelnet As New Telnet()

Public Sub Connect() Implements IComm.Connect


   'Start receiving data from host

End Sub

Public Event ReceiveEnd(strMessage As String) Implements IComm.DataReceived
Private Sub Telnet_EndReceive(ByVal sender As Object, _
    ByVal e As Dart.PowerTCP.Telnet.SegmentEventArgs) _
    Handles mobjTelnet.EndReceive

    If mobjTelnet.Connected = True Then
          SyncLock (mstrReceivedMessage)
            mstrReceivedMessage = mstrReceivedMessage.Append(e.Segment.ToString)
          End SyncLock
    End If

End Class

I would need some assistance to convert it to version 4.4. Any assistance would be appreciated.

Thank you for your post.

With the release of version 4.x, we've moved to a multithreading-centric design. A multithreaded implementation demonstrating a read loop can be found in our help documentation here:
