• Is it posibble to send websocket data over 126 chars?

  - by Udi Talias

  Its seems that everybody says that it is possible to send over 126 chars of data over websocket. I looked at many websocket server examples on the web and non of them can transfer over 126 chars from client to server and from server to client. I understand that it is something with dataframes and opcodes but i never figured it out. I'm using C#. Can somebody please put some light on this subject? any code example for receiving and sending data over 126 chars will be very very thankful

• How can I get my div id to reload via ajax and jquery

  - by Matt Nathanson

  I'm creating a CMS using jQuery and AJAX. When I click, my "Add Campaign" buttom, it creates a unique client ID in the DB and on a hard reload, the new client shows up in its container. I am trying to use ajax to reload the container on the fly and I'm not having the exact luck i am hoping for. I can get it to reload, but it's like it's pulling in descriptions of each of the clients as well! function AddNewClient() { dataToLoad = 'clientID=' + clientID + '&addClient=yes'; $.ajax({ type: 'post', url: '/clients/controller.php', datatype: 'html', data: dataToLoad, target: ('#clientssidebar'), async: false, success: function(html){ $('#clientssidebar').html(html); }, error: function() { alert('An error occured!'); } }); };

• How to Transfer Large File from MS Word Add-In (VBA) to Web Server?

  - by Ian Robinson

  Overview I have a Microsoft Word Add-In, written in VBA (Visual Basic for Applications), that compresses a document and all of it's related contents (embedded media) into a zip archive. After creating the zip archive it then turns the file into a byte array and posts it to an ASMX web service. This mostly works. Issues The main issue I have is transferring large files to the web site. I can successfully upload a file that is around 40MB, but not one that is 140MB (timeout/general failure). A secondary issue is that building the byte array in the VBScript Word Add-In can fail by running out of memory on the client machine if the zip archive is too large. Potential Solutions I am considering the following options and am looking for feedback on either option or any other suggestions. Option One Opening a file stream on the client (MS Word VBA) and reading one "chunk" at a time and transmitting to ASMX web service which assembles the "chunks" into a file on the server. This has the benefit of not adding any additional dependencies or components to the application, I would only be modifying existing functionality. (Fewer dependencies is better as this solution should work in a variety of server environments and be relatively easy to set up.) Question: Are there examples of doing this or any recommended techniques (either on the client in VBA or in the web service in C#/VB.NET)? Option Two I understand WCF may provide a solution to the issue of transferring large files by "chunking" or streaming data. However, I am not very familiar with WCF, and am not sure what exactly it is capable of or if I can communicate with a WCF service from VBA. This has the downside of adding another dependency (.NET 3.0). But if using WCF is definitely a better solution I may not mind taking that dependency. Questions: Does WCF reliably support large file transfers of this nature? If so, what does this involve? Any resources or examples? Are you able to call a WCF service from VBA? Any examples?

• Playback audio data with GWT

  - by Henrik

  I am creating a GWT client application which interacts with a server and I am getting all my response data from the server in JSON format. Amongst others there are wave data on the server's database which I would like to retrieve and then playback on the client. I am able to get the wave data as an array of bytes in the JSON format. My problem is, how do I playback the wave array data in a browser? Is it even possible or do I have to find another solution? I've searched the web and found some GWT packages which are able to playback sound, but they are all playing back directly from an url.

• to write log files in two different files

• WCF App using Peer Chat app as example does not work.

  - by splate

  I converted a VB .Net 3.5 app to use peer to peer WCF using the available Microsoft example of the Chat app. I made sure that I copied the app.config file for the sample(modified the names for my app), added the appropriate references. I followed all the tutorials and added the appropriate tags and structure in my app code. Everything runs without any errors, but the clients only get messages from themselves and not from the other clients. The sample chat application does run just fine with multiple clients. The only difference I could find is that the server on the sample is targeting the framework 2.0, but I assume that is wrong and it is building it in at least 3.0 or the System.ServiceModel reference would break. Is there something that has to be registered that the sample is doing behind the scenes or is the sample a special project type? I am confused. My next step is to copy all my classes and logic from my app to the sample app, but that is likely a lot of work. Here is my Client App.config: <client><endpoint name="thldmEndPoint" address="net.p2p://thldmMesh/thldmServer" binding="netPeerTcpBinding" bindingConfiguration="PeerTcpConfig" contract="THLDM_Client.IGameService"></endpoint></client> <bindings><netPeerTcpBinding> <binding name="PeerTcpConfig" port="0"> <security mode="None"></security> <resolver mode="Custom"> <custom address="net.tcp://localhost/thldmServer" binding="netTcpBinding" bindingConfiguration="TcpConfig"></custom> </resolver> </binding></netPeerTcpBinding> <netTcpBinding> <binding name="TcpConfig"> <security mode="None"></security> </binding> </netTcpBinding> </bindings> Here is my server App.config: <services> <service name="System.ServiceModel.PeerResolvers.CustomPeerResolverService"> <host> <baseAddresses> <add baseAddress="net.tcp://localhost/thldmServer"/> </baseAddresses> </host> <endpoint address="net.tcp://localhost/thldmServer" binding="netTcpBinding" bindingConfiguration="TcpConfig" contract="System.ServiceModel.PeerResolvers.IPeerResolverContract"> </endpoint> </service> </services> <bindings> <netTcpBinding> <binding name="TcpConfig"> <security mode="None"></security> </binding> </netTcpBinding> </bindings> Thanks ahead of time.

• Tool to measure Render time

  - by Noob

  Hi Folks, Is there a tool out there to measure the actual Render time of an element(s) on a page? I don't mean download time of the resources, but the actual time the browser took to render something. I know that this time would vary based on factors on the client machine, but would still be very handy in knowing what the rendering engine takes a while to load. I would imagine this should be a useful utility since web apps are becoming pretty client heavy now. Any thoughts?

• How to get server message correctly

  - by Leo

  Problem I send the message "12345" from the socket server to the client: myPrintWriter.println("12345"); After that I read this message on client: int c; while ((c = inputStream.read( )) != -1) { byte[] buffer2 = new byte[1]; buffer2[0] = (byte) c; String symbol = new String(buffer2 , "UTF-8"); String symbolCode = Integer.toString((int)buffer2[0]); Log.v(symbol, symbolCode); } Log.v("c == -1", "Disconnected"); What I see in log: With out.println("abcrefg"); Why? I think it's line termination symbol. I need to get string "12345" or any other and next strings correctly. Help me please.

• Store form values for later submission

  - by kim griggs

  I have a Rails app that lets users create tutorials and quizzes. There are many users taking the quizzes and many quizzes in a tutorial. My client wants the quiz results to persist when a student navigates away from the quiz. So the use case would be: User starts to take quiz User answers some of the questions User navigates away from quiz to check a fact in the tutorial User goes back to quiz and their answers are still there User finishes quiz and submits Now this would be pretty easy to do if I enforced a "Save" submit so that the answers could be stored in a session or whatever, but the client (and I agree) thinks people will not remember to save before navigating away. Looking for advice on how to approach this. I'm thinking an observer and cookies.

• BlackBerry OS 7.1 secured TLS connection is closed after very short time

  - by MrVincenzo

  To make a long story short: Same client-server configuration, same network topology, same device (Bold 9900) - works perfectly well on OS 7.0 but doesn't work as expected on OS 7.1 and the secured tls connection is being closed by the server after a very short time. My application opens a secured tls connection to a server. The connection is kept alive by a application layer keep-alive mechanism and remains open until the client closes it. Attached is a simplified version of the actual code that opens connection and reads from the socket. The code works perfectly on OS 5.0-7.0 but doesn't work as expected on OS 7.1. When running on OS 7.1, the blocking read() returns with -1 (end of the stream has been reached) after very short time (10-45 seconds). For OS 5.0-7.0 the call to read() remains blocking until next data arrives and the connection is never closed by the server. Connection connection = Connector.open(connectionString); connInputStream = connection.openInputStream(); while (true) { try { retVal = connInputStream.read(); if (-1 == retVal) { break; // end of stream has been reached } } catch (Exception e ) { // do error handling } // data read from stream is handled here } UPDATE 1: Apparently, the problem appears only when I use secured tls connection (either using mobile network or WiFi) on OS 7.1. Everything works as expected when opening a non secured connection on OS 7.1. For tls on mobile networks I use the following connection string: connectionString = "tls://someipaddress:443;deviceside=false;ConnectionType=mds-public;EndToEndDesired"; For tls on Wifi I use the following connection string: connectionString = "tls://someipaddress:443;deviceside=true;interface=wifi;EndToEndRequired" UPDATE 2: The connection is never idle. I am constantly receiving and sending data on it. The issue appears both when using mobile connection and WiFi. The issue appears both on real OS 7.1 devices and simulators. I am starting to suspect that it is somehow related either to the connection string I am using or to the tls handshake. UPDATE 3: According to Wireshark's captures that I made with the OS 7.1 simulator, the secured tls connection is being closed by the server (client receives FIN). For the moment I don't have the server's private key therefore I unable to debug the tls handshake.

• Class interaction

  - by user1264391

  Ok so I'm doing a simulation about a "Mall" I have many classes in the same "level" which corresponds to each person's personality. For example I have the class: clown, thief, assassin, materialist, etc. in the same level And a father class called Clients. In the Client class I have some methods for eating,walking, etc. and each specific class has a specific method, the thief steals, assassin kills, etc. I was wondering how could I put every "client" in a list and still cast every specific method?

• Why is new showat attribute required when using code generation?

  - by Patrick Karcher

  When I generate code using T4 templates in Visual Studio 2010, I get the following error for each of my asp controls when I try to compile: Control "ddState" is missing required attribute "showat". I have never gotten this error in previous versions of .NET. Further, I don't get this error when I manually construct my pages either by dragging/dropping, nor do I get it when I type out the control text myself. When I generate code, I have to manually add showat="client" to my tag for the compiler to be happy. It was my understanding that I never had to explicitly specify this tag. The following: <asp:dropdownlist id="ddState" runat="server" showat="client" /> solves the problem. Why do I have to add this to generated code but not other times? (It's a VS-2010 webforms project, using VB, in case that makes a difference.)

• Syncing SQL Server 2008 Databases over HTTP using WCF & Sync Framework

  - by Raj

  I've tried to get a solution for the above said question from MSDN Social and other resources from Microsoft. I was specifically looking for offline scenarios where client come online only to fetch updates from the Server. There are plenty of articles on Sync covering Sql CE but MSFT team seems to be ignoring questions from the community on Syncing with Sql Express clients. There is no standard provider for Sql Express client yet, and Sql 2008 change tracking is not supported in the latest release too. Since Sql Replication is an expensive alternative, I have to go with Sync Framework. Have anyone here in SO worked with Sync Framework, syncing through WCF endpoints? Please share code samples or sample projects.

• Is sending a PDF as encoded byte array in XML sensible

  - by simonjwoods

  Hi I am looking to return a PDF from a webservice call. (ATM, a custom proxy is required at the client-side) AFAICS, there are 2 ways of doing it a) Return the link to a web-accessible location b) Encode the PDF and include it in the XML In my circumstance, a) will require 2 trips from the client, the first to get the path and the second to get the file. However, wrt b), this link (http://www.coderanch.com/t/279020/Streams/java/wrting-bytearray-xml-file#1283263) suggests that it isn't a good idea to encode a PDF, though without explanation. I'd be grateful if someone would offer recommendations of the above (and potentially, other alternatives). Many thx Simon

• How can I consume a WSDL (SOAP) web service in Python?

  - by DavidM

  I want to use a WSDL SOAP based web service in Python. I have looked at the Dive Into Python code but the SOAPpy module does not work under Python 2.5. I have tried using suds which works partly, but breaks with certain types (suds.TypeNotFound: Type not found: 'item'). I have also looked at Client but this does not appear to support WSDL. And I have looked at ZSI but it looks very complex. Does anyone have any sample code for it? The WSDL is https://ws.pingdom.com/soap/PingdomAPI.wsdl and works fine with the PHP 5 SOAP client.

• Webhook data for Orders Paid

  - by David Lazar

  A client recently requested some fancy processing based off of the Gateway attribute registered with a Paid order. When I receive, validate and inspect the JSON of the order, I am logging the gateway attribute and finding it is nil at times. When I check the order using the API after the Webhook, the gateway attribute is present and matches the one rendered in the Shop admin. Is there an explanation for why the gateway can at times be nil? This prevents me from taking care of the client's requested processing.

• XML-RPC in CodeIgniter is for creating a API?

  - by ajsie

  I have read some tutorials about creating an API and i wonder if XML-RPC and XML-RPC server in CodeIgniter are for creating this? If yes, what are the benefits of using these classes rather than im just using regular class/methods/params to create my API interface. This is what it said in the documentation: Quite simply it is a way for two computers to communicate over the internet using XML. One computer, which we will call the client, sends an XML-RPC request to another computer, which we will call the server. Once the server receives and processes the request it will send back a response to the client.

• How to set up dynamically Part in MultipartRequestEntity

  - by ee_vin

  Hello, I'm using commons-httpclient-3.1 inside my android application. And I would like to know if it possible to manipulate Part (org.apache.commons.httpclient.methods.multipart.Part) dynamically? Essentially adding new FilePart and new StringPart at runtime before sending the request. Every example I've found until now suppose that you know how many fields you are dealing with. Ex: File f = new File("/path/fileToUpload.txt"); PostMethod filePost = new PostMethod("http://host/some_path"); Part[] parts = { new StringPart("param_name", "value"), new FilePart(f.getName(), f) }; filePost.setRequestEntity( new MultipartRequestEntity(parts, filePost.getParams()) ); HttpClient client = new HttpClient(); int status = client.executeMethod(filePost); code from http://hc.apache.org/httpclient-3.x/apidocs/org/apache/commons/httpclient/methods/multipart/MultipartRequestEntity.html Android specific thread: http://groups.google.com/group/android-developers/browse_thread/thread/0f9e17bbaf50c5fc Thank you

• TcpListener problem - re-binding to same port with different local addresses

  - by Zvika

  I'm trying to do the following: listen on some port for loopback connections only, and then start listening on any IP address. Here is the code: TcpListener l1 = new TcpListener(new IPEndPoint(IPAddress.Loopback, 12345)); l1.Start(); Socket s = l1.AcceptSocket(); Console.ReadKey(); //s.Close(); l1.Stop(); TcpListener l2 = new TcpListener(new IPEndPoint(IPAddress.Any, 12345)); l2.Start(); l2.AcceptSocket(); Console.ReadKey(); The problem is that if a client connects while listening on the Loopback address (l1), then no other client can connect to the Loopback address when the second listener (l2) starts listening. why is that? Another thing I noticed is that if I close all clients that connected to l1 (the remarked line), then l2 does accept loopback connections. Any ideas?

• How to extend WCF returned class properly?

  - by vikasde

  I am using a WCF service in my project. This service returns a class called "Store". I created a new local class which inherits from "Store". My class is called "ExtendedStore". My ExtendedStore looks like this: class ExtendedStore : StoreManagerService.Store { public int Id; .... } Now I am using the WCF service to cast to my class using the following code: StoreManagerService.StoreClient client = new StoreManagerService.StoreClient(); ExtendedStore store = (ExtendedStore) client.GetStore(); // bombs here I am not able to cast the returned Store class from the service to my ExtendedStore class. I get the below error message: Unable to cast object of type 'ConsoleApplication1.StoreManagerService.Store' to type 'ConsoleApplication1.ExtendedStore'. Shouldn't I be able to cast it? If not, is there a workaround?

• Using microsoft report viewer with objects

  Ive got some nested objects that I am trying to generate reports for. A BackupClient contains BackupVersions and BackupVersions contain BackupFiles. I passed in the list of BackupClients - and the report displays the client name, etc.... but to display the versions - It says I have to have a Binding Source for BackupVersions. If I pull all of the versions out of the clients and put them in a different BindingSource, then my data is no longer together - how is the report viewer going to list the versions for client X - if I just have a binding source with ALL clients versions in it?
