    <p>Here's my code:</p> <pre><code>private void OnReceive(IAsyncResult result) { NetStateObject state = (NetStateObject)result.AsyncState; Socket client = state.Socket; int size = client.EndReceive(result); byte[] data = state.Buffer; object data = null; using (MemoryStream stream = new MemoryStream(data)) { BinaryFormatter formatter = new BinaryFormatter(); data = formatter.Deserialize(stream); } //todo: something with data client.BeginReceive( state.Buffer, 0, NetStateObject.BUFFER_SIZE, SocketFlags.None, OnReceive, state ); } </code></pre> <p>state.Buffer has a maximum size of NetStateObject.BUFFER_SIZE (1024). Firstly, is this too big or too small? Second, if I send something larger than that, my deserialize messes up because the object it is trying to deserialize doesnt have all the information (because not all the data was sent). How do I make sure that all my data has been received before I try to construct it and do something with it?</p> <p><strong>Completed Working Code</strong></p> <pre><code> private void OnReceive(IAsyncResult result) { NetStateObject state = (NetStateObject)result.AsyncState; Socket client = state.Socket; try { //get the read data and see how many bytes we received int bytesRead = client.EndReceive(result); //store the data from the buffer byte[] dataReceived = state.Buffer; //this will hold the byte data for the number of bytes being received byte[] totalBytesData = new byte[4]; //load the number byte data from the data received for (int i = 0; i &lt; 4; i++) { totalBytesData[i] = dataReceived[i]; } //convert the number byte data to a numan readable integer int totalBytes = BitConverter.ToInt32(totalBytesData, 0); //create a new array with the length of the total bytes being received byte[] data = new byte[totalBytes]; //load what is in the buffer into the data[] for (int i = 0; i &lt; bytesRead - 4; i++) { data[i] = state.Buffer[i + 4]; } //receive packets from the connection until the number of bytes read is no longer less than we need while (bytesRead &lt; totalBytes + 4) { bytesRead += state.Socket.Receive(data, bytesRead - 4, totalBytes + 4 - bytesRead, SocketFlags.None); } CommandData commandData; using (MemoryStream stream = new MemoryStream(data)) { BinaryFormatter formatter = new BinaryFormatter(); commandData = (CommandData)formatter.Deserialize(stream); } ReceivedCommands.Enqueue(commandData); client.BeginReceive( state.Buffer, 0, NetStateObject.BUFFER_SIZE, SocketFlags.None, OnReceive, state ); dataReceived = null; totalBytesData = null; data = null; } catch(Exception e) { Console.WriteLine("***********************"); Console.WriteLine(e.Source); Console.WriteLine("***********************"); Console.WriteLine(e.Message); Console.WriteLine("***********************"); Console.WriteLine(e.InnerException); Console.WriteLine("***********************"); Console.WriteLine(e.StackTrace); } } </code></pre>

    1. COJust a quick thought... did you try to call stream.Flush() just before deserializing data? Just to make sure the data is there before deserializing

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
