| Author | Forum: PowerTCP Sockets for .NET (Secure and Standard) Topic: Syntax for SERVER to send messages to all connected clients |
| TMS From: Kula, USA Posts: 6 Member Since: 02/01/11 |
posted February 1, 2011 3:43 PM Hi, In a Winforms app containing a SERVER component, I would like to send a message to all the connected clients. I start the server with server1.Listen(socketnum); At this point, clients can connect, and I see them with server1.Connections.Count Intuitively, I would think something like this would be the C# syntax: for (int i=0;i<server1.Connections.Count;i++){ server1.Connection[i].Send("Hello"+\r\n); } The above methods do not exist. Can somebody please suggest the proper way to accomplish this. Thanks |

posted February 1, 2011 4:09 PM Hello, Are you looking for the Write method? In the 4.x redesign, we changed our methods to be more in line with the Streams interface. |

posted February 1, 2011 4:36 PM Yes, I am looking for the proper syntax to invoke the Write or WriteTo method (writing from a server to all attached clients). Although I recently bought a subscription to .Net PowerTCP Sockets 4.3, I am maintaining this application from an older PowerTCP version (purchased March of '10) so the Streams modification you mention may not apply. Can you point me to an example of implementing this? |

posted February 1, 2011 4:56 PM Hello, I meant that there is a Write() method, not a Send() method in our 4.x product, I'm sorry for the confusion. The sample you provide should perform what you are referring to, but I noticed that you are referencing server1.Connection[i], not server1.Connections[i] There is a similar example in the help documentation for the Connections property, copied here: // Echo data back to all clients foreach(Tcp tcp in server1.Connections) { // Preface text with user name (from Tcp.Tag) and send tcp.Stream.Write(e.Tcp.Tag.ToString() + ": " + text + "\r\n"); } |
