The c++ server already have a native c++ client, now we need to add a Silverlight client without any modification to the server. The applications are biased to use minimal data transfer. so we cannot use xml ( which will also create changes in server ) Recreating the data byte-by-byte is possible at client, but we would like to know of other possible methods.

I want to develop tcp socket application,forwhich want to use c++ tcp server and silverlight tcp client(web client).At server filling data in a structure and sending to the client,Is there any way to retain the values of the structure at client side?Or can i serialize the sending data as a class object in silverlight?

My scenario is like this. SocketReceiveCallback(object sender, SocketAsyncEventArgs e ) { // read data from e.Buffer. if ( dataReceived == TotalDataSize ) // checks of the complete reception of one image { // update the GUI using the received data. System.Diagnostics.Debug.WriteLine( “ received image “ ); Dispatcher.BeginInvoke(new DisplayImageDelgate(DislayImageData), imageData); // imageData is a class containing the received data } Else { // call socket.receiveAsync() to get next set of data. } } private void DisplayImageData (MyImageData data) { if (data.ImageStream != null) { BitmapImage bmp = new BitmapImage(); bmp.SetSource(new MemoryStream(data.ImageStream)); myReceivedImageCtrl.Source = bmp; //GUI update should happen at this point. System.Diagnostics.Debug.WriteLine( “ Draw image “ ); } } Please note that my application, there is continues async requests to server ( corresponding to user action ) and server responds with a stream of image data( eg:- 100 images. The application needs to update the GUI immediately after each image is received ( even while the server streams the data). In the above case although the SocketReceiveCallback is getting the data continuously from server, the GUI update happens only after all the data receive is completed( which can take a long time ). It seems that although the DisplayImage function is invoked using BeginInvoke, the system actually executes the display function at a later stage, causing ‘jumping’ image displays The debug trace obtained was:- received image received image received image received image Draw image Draw image Draw image Instead of the needed received image Draw image received image Draw image received image Draw image What could be done? Thanks and Regards JS

I have a silverlight application,that communicating and getting data through socket communication.At each Receive callback i want to get data and update in the GUI at the moment itself.In this case sending and receiving data asynchronously,but the delegate for GUI updation in action only after all receive callbacks.How can i execute GUI updations sequentially with each callback?

Thanks for the answer,But I already used [ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Multiple],but the problem still exists,Also implemented the service as asynchronously,Could you suggest any other solutions?

I have a silverlight application which uses wcf service hosted in a wpf application, but when I try to connect more then one client the second client always waits until the first client completes the call.How can I make WCF to accept calls from multiple clients at the same time?
