Next, attach an event handler to handle the ReceiveCompleted event. The Socket object itself does not have any event handlers associated with it. Use the Completed event handler with the SocketAsyncEventArgs object. For example, the following code adds an OnReceiveCompleted() event handler to a SocketAsyncEventArgs object args:

args.Completed += new EventHandler<SocketAsyncEventArgs>(OnReceiveCompleted);

If the connection completed or send completed event handler is still attached to the SocketAsyncEventArgs object, you can remove it before adding the receive event handler. To receive the data to the remote host, use the ReceiveAsync() method of the Socket object and pass the SocketAsyncEventArgs object as shown in the following line of code. When data is received from the remote host, the OnReceiveCompleted() event handler is called:

Closing a socket

To close a socket, first call the Shutdown() method of the Socket object. The Shutdown() method finalizes any pending operations on the socket and then signals the remote host at the endpoint that the connection should be closed. This way, any data that isn t sent or received can be flushed before the socket is closed. Check the Connected attribute of the Socket object to verify if the socket is actually connected prior to calling the Close() method to close the connection. For example:

The code in Listings 14.9 and 14.10 shows an example Silverlight application that opens a socket connection to a basic Windows service that accepts a format string then periodically writes a formatted string representing the server timeout on the socket. The code in Listing 14.9 defines a simple interface with three Button controls dateBtn, timeBtn, and fullBtn. Each of these buttons initiates a request to open a socket and send a specific format string to the service. A TextBlock, serverText, is defined to display the text string returned on the socket.

The code in Listing 14.10 first implements the System.Net library for the DnsEndPoint class, the System.Net.Sockets library for the Socket and SocketAsyncEventArgs classes, and the System.Text library for the Encoding class. Inside the Page() constructor, the code attaches Click event handler functions to the timeBtn, dateBtn, and fullBtn controls. Each of these handlers simply sets the timeDateFormat variable and then calls the doGetData() function.

Control ean13+5 size on .net

Inside the doGetData() function, the code creates a DnsEndPoint object ePoint. The host of ePoint is set to Application.Current.Host.Source.DnsSafeHost, which is the unescaped host name of the Silverlight application. We can use this address because the socket service project is part of the solution in Visual Studio. Next, the code creates a Socket object, using the following code:
Control datamatrix data for visual c#
to assign barcode data matrix and gs1 datamatrix barcode data, size, image with c#.net barcode sdk
DnsEndPoint ePoint = new DnsEndPoint(Application.Current.Host.Source.DnsSafeHost, 4510); Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
Control upc-a supplement 2 data with excel

The code then creates a SocketAsyncEventArgs object, sArgs, and sets the UserToken property to the Socket object socket and the RemoteEndPoint property to the DnsEndPoint object ePoint. Next, the code attaches the OnConnectCompleted() event to the Connected event property of the sArgs object. Finally, the ConnectAsync() function of the Socket object is called using the sArgs object to open the socket. When the Socket connect returns, the OnConnectCompleted() event handler is called. Typically, you should verify the connection opened successfully by checking the SocketError property of the SocketAsyncEventArgs argument passed to the handler. We don t implement error handling in this example to keep it simple. Inside the OnConnectCompleted() function, a byte array is created and encoded with the value of the timeDateFormat string. Next, the byte array is attached to the SocketAsyncEventArgs argument using the following code:
Control data for microsoft word
to print ean 128 barcode and ean / ucc - 14 data, size, image with word documents barcode sdk
Byte[] bytes = Encoding.UTF8.GetBytes(timeDateFormat); e.SetBuffer(bytes, 0, bytes.Length);
The code then removes the OnConnectedCompleted() event handler from the Completed property of the SocketAsyncEventArgs argument and attaches the OnSocketSendCompleted() event handler using the following lines of code. This sets up the socket to be able to send data and the Silverlight application to be able to respond to the send completion event:
e.Completed -= new EventHandler<SocketAsyncEventArgs>(OnConnectCompleted); e.Completed += new EventHandler<SocketAsyncEventArgs>(OnSocketSendCompleted);
Next, the code gets the Socket object from the UserToken property of the SocketAsyncEventArgs argument and sends the data using the following lines of code. The UserToken and RemoteEndPoint properties are still set to the values used to open the socket:
