Each time a new connection is received, a new PolicyConnection object is created to deal with it. The task of serving the policy file is handled by the PolicyConnection class, which you ll consider in the next section. The final ingredient in the PolicyServer class is a Stop() method that stops waiting for requests. The application can call this if it s shutting down: ... Private isStopped As Boolean Public Sub [Stop]() isStopped = True Try listener.Stop() Catch err As Exception Console.WriteLine(err.Message) End Try End Sub End Class To start the policy server, the Main() method of the server application uses this code: Shared Sub Main(ByVal args As String()) Dim policyServer As New PolicyServer("clientaccesspolicy.xml") policyServer.Start() Console.WriteLine("Policy server started.") Console.WriteLine("Press Enter to exit.") ' Wait for an enter key. You could also wait for a specific input ' string (like "quit") or a single key using Console.ReadKey(). Console.ReadLine() policyServer.Stop() Console.WriteLine("Policy server shut down.")

The PolicyConnection class has a simple task. When created, it stores a reference to the policy file data. Then, when the HandleRequest() method is called, it accesses the network stream for the new connection and attempts to read from it. If all is well, the client will have sent a string that contains the text <policy-file-request/> . After reading that string, the client writes the policy data to that stream, and closes the connection. Here s the complete code: Public Class PolicyConnection Private client As TcpClient Private policy As Byte() Before exploring what some of these variables do, let s go through Connection.m. We will look at it in five parts: Initialization, closing and cleanup, reading data, writing data, and handling stream events. In order to get the whole listing, concatenate all five parts into one file (or get the final version from the project archive). how to read pdf file in asp.net c#Reading Contents From PDF, Word, Text Files In C# - C# Corner

Public Sub New(ByVal client As TcpClient, ByVal policy As Byte()) Me.client = client Me.policy = policy End Sub ' The request that the client sends. Private Shared policyRequestString As String = "<policy-file-request/>" Public Sub HandleRequest() Dim s As Stream = client.GetStream() ' Read the policy request string. Dim buffer As Byte() = New Byte(policyRequestString.Length - 1){} ' Only wait 5 seconds. That way, if you attempt to read the request string ' and it isn't there or it's incomplete, the client only waits for 5 ' seconds before timing out. client.ReceiveTimeout = 5000 s.Read(buffer, 0, buffer.Length) ' Send the policy. (Optionally, you could verify that the policy request ' contains the content you expect.) s.Write(policy, 0, policy.Length) ' Close the connection. client.Close() Console.WriteLine("Served policy file.") End Sub End Class You now have a complete, fully functioning policy server. Unfortunately, you can t test it yet. That s because Silverlight doesn t allow you to explicitly request policy files. Instead, it automatically requests them when you attempt to use a socket-based application. And before you build a client for that socket-based application, you need to build the server. Here s the first part of Connection.m, which handles initialization: Tip Notice that this also provides its own documentation. Because plugins are also classes all their own, they can be subclassed by even more specialized plugins down the road. This makes it important to include thorough documentation even at this level, to help ensure proper usage later. #import "Connection.h" #import <CFNetwork/CFSocketStream.h> @implementation Connection @synthesize delegate, userInfo; @synthesize inputStream, outputStream; - (id)initWithNativeSocketHandle:(CFSocketNativeHandle)nativeSocketHandle { CFReadStreamRef readStream; CFWriteStreamRef writeStream; CFStreamCreatePairWithSocket(kCFAllocatorDefault, nativeSocketHandle, &readStream, &writeStream); self.inputStream = (NSInputStream*)readStream; self.outputStream = (NSOutputStream*)writeStream; return self; } - (id)initWithInputStream:(NSInputStream*)istr outputStream:(NSOutputStream*)ostr { self.inputStream = istr; self.outputStream = ostr; return self; } - (BOOL)connect { if ( !inputStream || !outputStream ) { return NO; } incomingDataBuffer = [[NSMutableData alloc] init]; outgoingDataBuffer = [[NSMutableData alloc] init]; CFReadStreamSetProperty((CFReadStreamRef)inputStream, Although you can create the messaging server as a separate application, it s tidier to place it in the same application as the policy server. Because the policy server does its listening and request-handling work on separate threads, the messaging server can do its work at the same time. Like the policy server, the messaging server is broken into two classes: MessengerServer, which listens for requests and tracks clients, and MessengerConnection, which handles the interaction of a single client. To see the full code, refer to the downloadable examples for this chapter. In this section, you ll just explore the differences between the policy server and messaging server. kCFStreamPropertyShouldCloseNativeSocket, kCFBooleanTrue); CFWriteStreamSetProperty((CFWriteStreamRef)outputStream, kCFStreamPropertyShouldCloseNativeSocket, kCFBooleanTrue); inputStream.delegate = self; [inputStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode]; outputStream.delegate = self; [outputStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode]; outputStreamWasOpened = NO; nextMessageSize = -1; [inputStream open]; [outputStream open]; return YES; } how to read pdf file in asp.net c#Reading PDF documents in .Net - Stack Overflow
