• 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.

• command design pattern usage

  - by sagie

  Hi. I've read 3 descriptions of the command design pattern: wikipedia, dofactory and source making. In all of them, the UML shows a relation between the client to the receiver & the concrete command, but no relation to the invoker. But in all 3 examples the client is the one that initiates the invoker and call its Execute method. I think that should be a relation to the invoker as well. Am I missing somthing in here? Maybe even a basic UML knowladge?

• Transfer of directory structure over network

  - by singh

  I am designing a remote CD/DVD burner to address hardware constraints on my machine. My design works like this: (analogous to a network printer) Unix-based machine (acts as server) hosts a burner. Windows-based machine acts as client. Client prepares data to burn and transfers it to the server. Server burns the data on CD/DVD. My question is: what is the best protocol to transfer data over the network (Keeping the same directory hierarchy) between different operating systems?

• 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?

• PHP socket UDP communication

  - by Ghedeon

  Server works fine, but the problem is the client doesn't receive anything. server.php <?php $buf_size = 1024; $socket = stream_socket_server("udp://127.0.0.1:3127", $errno, $errstr, STREAM_SERVER_BIND); do { $str = stream_socket_recvfrom($socket, $buf_size, 0, $peer); $str = "abc"; stream_socket_sendto($socket, $str, strlen($str), 0, $peer); } while (true); ?> client.php <?php $fp = stream_socket_client("udp://127.0.0.1:3127", $errno, $errstr); if (!$fp) { echo "$errno - $errstr<br />\n"; } else { fwrite($fp, "1 2 3"); echo fread($fp, 15); fclose($fp); } ?>

• choosing an image locally from http url and serving that image without a server round trip

  - by serverman

  Hi folks I am a complete novice to Flash (never created anything in flash). I am quite familiar with web applications (J2EE based) and have a reasonable expertise in Javascript. Here is my requirement. I want the user to select (via an html form) an image. Normally in the post, this image would be sent to server and may be stored there to be served later. I do not want that. I want to store this image locally and then serve it via HTTP to the user. So, the flow is: 1. Go to the "select image url":mywebsite.com/selectImage Browse the image and select the image This would transfer control locally to some code running on the client (Javascript or flash), which would then store the image locally at some place on the client machine. Go to the "show image url": mywebsite.com/showImage This would eventually result in some client code running on the browser that retrieves the image and renders it (without any server round trips.) I considered the following options: Use HTML5 local storage. Since I am a complete novice to flash, I looked into this. I found that it is fairly straightforward to store and retrieve images in javascript (only strings are allowed but I am hoping storing base64 encoded strings would work at least for small images). However, how do I serve the image via http url that points to my server without a server round trip? I saw the interesting article at http://hacks.mozilla.org/category/fileapi/ but that would work only in firefox and I need to work on all latest browsers (at least the ones supporting HTML5 local storage) Use flash SharedObjects. OK, this would have been good - the only thing is I am not sure where to start. Snippets of actionscripts to do this are scattered everywhere but I do not know how to use those scripts in an actual html page:) I do not need to create any movies or anything - just need to store an image and serve it locally. If I go this route, I would also use it to store other "strings" locally. If you suggest this, please give me the exact steps (could be pointers to other web sites) on how to do this. I would like to avoid paying for any flash development environment software ideally:) Thank you!

• Using microsoft report viewer with objects

  - by Jack

  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?

• 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.

• Using Angularjs with server side templates

  - by codecollision

  For SEO purposes the server renders out the full html template for a given URL on initial load. The site uses angularjs which detects the URL route and renders a client template from the JSON API. For example, you navigate to: /blog/post-title Server responds with post-title content. Angular loads, detects route: /blog/:post_slug and begins to load JSON and render client side template from response. Obviously what Angular does is fine when links are followed after the initial load, but on first load it duplicates effort. My question is if there is a clean way to prevent this situation.

  I'm using System.Net.Mail to send out a few emails. The emails are being sent by our internal mail server to local addresses. However all of the messages are going straight to junk in Outlook. The messages are being sent from valid email addresses. What would be causing our our servers to label it as junk? MailMessage msg = new MailMessage(); msg.IsBodyHtml = true; msg.Subject = subject; msg.Body = body; msg.From = new MailAddress(from); msg.To.Add(to); SmtpClient client = new SmtpClient(server, 25); client.Send(msg);

• 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?

• Help me with this logic (newbie) [migrated]

  - by Surendra

  I need to generate a half pyramid number series with the entered starting number and the number of lines in a html page using Javascript and show the result in html page . I have done the Java scripting and stuff . What I don't get is the logic to it. Take a look at this you may get an idea what I'm talking about: Here is my function in Javascript that will be triggered on a button click function doFunction(){ var enteredNumber=document.getElementById("start"); var lines=document.getElementById("lines"); var result; for(i=0;i<=lines.value;i++) { for(j=enteredNumber.value;j<=i;j++) { document.write(j + "&nbsp;" + "&nbsp;"); } document.write("<br />"); } } Help me with the logic to print following order: 1 1 2 1 2 3 1 2 3 4 1 2 3 4 5 There is a condition. I will specify $start and $lines. If $start = 5 and $lines = 3 then output should be like: 5 5 6 5 6 7 I have had used the for loop , but that doesn't work if I give my own start number that is higher than the number of lines. I actually need it done with Javascript, I have had done the necessary but I'm confused with the logic to generate such series (with the user given values) I had actually used two for loops to generate the regular number series like below 1 1 2 1 2 3 and so on.

• 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

• 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 to create a cross-plataform application, doing the interface modules (Mac/Qt/GTK+) in a totally

  - by Somebody still uses you MS-DOS

  I'm amazed at Transmission, a BT client. It has a Mac, a GTK+, a QT, a Web Client and a CLI interface to it. I tried reading some of it's source to understand how he creates all these interfaces, but no luck. Does the developer creates them using a single ide? Or does he create the interface logic in each specific environment (specially mac), "exports" this window code and integrates with the main logic? Is it possible to create that mac interface in another OS using an IDE? How did the developers create this software with so many interfaces, in a independent way?

• Stopping the manipulation of variables used for data collection?

  - by Ruinous

  I am working on a project in java and I was hoping to be able to collect statistics from the client and a possible problem that I fear will occur is the manipulation of the variables used for collection which will lead to illegitimate statistics. Is it in any way possible to prevent the manipulation of variables or is it always possible? For example: I want to log the actions made per hour from the client. The variable acting as a counter for the amount of actions performed is manipulated and a much larger amount is added to the counter. This data is then uploaded to the server (Of course using a multi-tier architecture to prevent even more possible problems) and considered 'legit.' Is there any way to prevent this?

• 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.)

• SSL_accept hangs... sometimes ( C, linux, openssl )

  - by zbigh

  I'm currently working on an embedded linux system. There are two crucial client applications on the system that connect to an external server ( on another embedded system, all written in C ). The two apps use different certificates. The ssl connection works... At least usually, but from time to time an error occures: the server hangs on SSL_accept() when accepting connection from one of the applications - the one using older certificates. Restarting the server application does not help, nor does restarting the client - the only way is to reboot the server system, unless I create a symbilic link to the new certificates used by the other app - only then will restarting the server app work. Never does the error occur when both applications use the same, new certificate. Could this happen due to some strange openssl cache or something like that?

• 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.

• How to? WCF customBinding over Https

  - by user663414

  Hi all, I'm trying to setup a WCF service for internal use, on our external facing web-farm (we dont have a web farm internally, and I need this service to have failover and load-balancing). Requirements: PerSession state, as we need the service to retain variable data for each session. HTTPS. After lots of googling i've read I needed to create a customBinding, which I've done, but not sure if it is correct. Larger message size, as one of the parameters is a byte[] array, which can be a max of 5mb. no requirement to manually edit the client-side app.config. ie, I need the Developer to just add the service reference, and then starts using the object without fiddly changing of app.config. Note: I've previously had this service working under HTTP correctly (using wsHttpBinding). I've also had it working under HTTPS, but it didn't support PerSession state, and lost internal variable values each function call. I'm currently getting this error from the test harness: Could not find default endpoint element that references contract 'AppMonitor.IAppMonitorWcfService' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element. NOTE: The error is arising on an Test Harness EXE, that has the WCF service referenced directly under Service References. This is not the problem of an exe referencing another object, that then references the WCF service, that i've read about. The WSDL is showing correctly when browsing to the URL. Web.Config: <system.serviceModel> <services> <service name="AppMonitor.AppMonitorWcfService" behaviorConfiguration="ServiceBehavior"> <endpoint address="" binding="customBinding" bindingConfiguration="EnablePerSessionUnderHttps" contract="AppMonitor.IAppMonitorWcfService"/> <endpoint address="mex" binding="mexHttpsBinding" contract="IMetadataExchange" /> </service> </services> <bindings> <customBinding> <binding name="EnablePerSessionUnderHttps" maxReceivedMessageSize="5242880"> <reliableSession ordered="true"/> <textMessageEncoding> <readerQuotas maxDepth="64" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> </textMessageEncoding> <httpsTransport authenticationScheme="Anonymous" requireClientCertificate="false"/> </binding> </customBinding> </bindings> <behaviors> <serviceBehaviors> <behavior name="ServiceBehavior"> <serviceMetadata httpsGetEnabled="true" httpGetEnabled="false"/> <serviceDebug includeExceptionDetailInFaults="true"/> </behavior> </serviceBehaviors> </behaviors> </system.serviceModel> EXE's App.config (auto-generated when adding the Service Reference): <configuration> <system.serviceModel> <bindings> <wsHttpBinding> <binding name="CustomBinding_IAppMonitorWcfService" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true" allowCookies="false"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> <reliableSession ordered="true" inactivityTimeout="00:10:00" enabled="true" /> <security mode="Transport"> <transport clientCredentialType="None" proxyCredentialType="None" realm="" /> <message clientCredentialType="Windows" negotiateServiceCredential="true" establishSecurityContext="true" /> </security> </binding> </wsHttpBinding> </bindings> <client /> </system.serviceModel> </configuration> I'm not sure why the app.config is showing wsHttpBinding? Shouldn't this be customBinding? I really dont want to have to edit the app.config, as this service will be used by dozens of developers, and I want them to just be able to add the Service Reference, and away they go... Using VS2008, .NET 3.51. I think server is IIS7, Win Server 2008, can confirm if needed.

• What do I need to distribute (keys, certs) for Python w/ SSL-socket connection?

  - by fandingo

  I'm trying to write a generic server-client application that will be able to exchange data amongst servers. I've read over quite a few OpenSSL documents, and I have successfully setup my own CA and created a cert (and private key) for testing purposes. I'm stuck with Python 2.3, so I can't use the standard "ssl" library. Instead, I'm stuck with PyOpenSSL, which doesn't seem bad, but there aren't many documents out there about it. My question isn't really about getting it working. I'm more confused about the certificates and where they need to go. Here are my two programs that do work: Server: #!/bin/env python from OpenSSL import SSL import socket import pickle def verify_cb(conn, cert, errnum, depth, ok): print('Got cert: %s' % cert.get_subject()) return ok ctx = SSL.Context(SSL.TLSv1_METHOD) ctx.set_verify(SSL.VERIFY_PEER|SSL.VERIFY_FAIL_IF_NO_PEER_CERT, verify_cb) # ?????? ctx.use_privatekey_file('./Dmgr-key.pem') ctx.use_certificate_file('Dmgr-cert.pem') # ?????? ctx.load_verify_locations('./CAcert.pem') server = SSL.Connection(ctx, socket.socket(socket.AF_INET, socket.SOCK_STREAM)) server.bind(('', 50000)) server.listen(3) a, b = server.accept() c = a.recv(1024) print(c) Client: from OpenSSL import SSL import socket import pickle def verify_cb(conn, cert, errnum, depth, ok): print('Got cert: %s' % cert.get_subject()) return ok ctx = SSL.Context(SSL.TLSv1_METHOD) ctx.set_verify(SSL.VERIFY_PEER, verify_cb) # ?????????? ctx.use_privatekey_file('/home/justin/code/work/CA/private/Dmgr-key.pem') ctx.use_certificate_file('/home/justin/code/work/CA/Dmgr-cert.pem') # ????????? ctx.load_verify_locations('/home/justin/code/work/CA/CAcert.pem') sock = SSL.Connection(ctx, socket.socket(socket.AF_INET, socket.SOCK_STREAM)) sock.connect(('10.0.0.3', 50000)) a = Tester(2, 2) b = pickle.dumps(a) sock.send("Hello, world") sock.flush() sock.send(b) sock.shutdown() sock.close() I found this information from ftp://ftp.pbone.net/mirror/ftp.pld-linux.org/dists/2.0/PLD/i586/PLD/RPMS/python-pyOpenSSL-examples-0.6-2.i586.rpm which contains some example scripts. As you might gather, I don't fully understand the sections between the " # ????????." I don't get why the certificate and private key are needed on both the client and server. I'm not sure where each should go, but shouldn't I only need to distribute one part of the key (probably the public part)? It undermines the purpose of having asymmetric keys if you still need both on each server, right? I tried alternating removing either the pkey or cert on either box, and I get the following error no matter which I remove: OpenSSL.SSL.Error: [('SSL routines', 'SSL3_READ_BYTES', 'sslv3 alert handshake failure'), ('SSL routines', 'SSL3_WRITE_BYTES', 'ssl handshake failure')] Could someone explain if this is the expected behavior for SSL. Do I really need to distribute the private key and public cert to all my clients? I'm trying to avoid any huge security problems, and leaking private keys would tend to be a big one... Thanks for the help!
