  • Business Objects Enterprise reporting using SDK client gives exception

    - by Dev_Karl
    Hi! We have a client that is using the SDK for invoking reports on the Business Objects Embedded Report Server. We can login, but when calling the openDocument method, something goes wrong. code: //logon IEnterpriseSession session = sessionMgr.logon(username, password, clusterNode, authType); .... clientDoc = reportAppFactory.openDocument(report, 0, locale); /*row 58 in exception*/ exception: com.crystaldecisions.sdk.occa.report.lib.ReportSDKServerException: Unable to connect to the server: . - Server not found or server may be down---- Error code:-2147217387 Error code name:connectServer at com.crystaldecisions.sdk.occa.managedreports.ras.internal.RASReportAppFactory.a(Unknown Source) at com.crystaldecisions.sdk.occa.managedreports.ras.internal.RASReportAppFactory.a(Unknown Source) at com.crystaldecisions.sdk.occa.managedreports.ras.internal.RASReportAppFactory.a(Unknown Source) at com.crystaldecisions.sdk.occa.managedreports.ras.internal.RASReportAppFactory.openDocument(Unknown Source) at com.reportclient.MyReportClient.getReportFromInfoStore(MyReportClient.java:58) ... 28 more Caused by: com.crystaldecisions.sdk.occa.report.lib.ReportSDKServerException: Unable to connect to the server: . - Server not found or server may be down---- Error code:-2147217387 Error code name:connectServer at com.crystaldecisions.sdk.occa.report.lib.ReportSDKServerException.throwReportSDKServerException(Unknown Source) at com.crystaldecisions.sdk.occa.managedreports.ras.internal.CECORBACommunicationAdapter.connect(Unknown Source) ... 32 more Caused by: com.crystaldecisions.enterprise.ocaframework.OCAFrameworkException$NotFoundInDirectory: Server not found or server may be down at com.crystaldecisions.enterprise.ocaframework.j.find(Unknown Source) at com.crystaldecisions.enterprise.ocaframework.AbstractServerHandler.buildServerInfo(Unknown Source) at com.crystaldecisions.enterprise.ocaframework.AbstractServerHandler.buildClusterInfo(Unknown Source) at com.crystaldecisions.enterprise.ocaframework.aa.for(Unknown Source) at com.crystaldecisions.enterprise.ocaframework.ServiceMgr.for(Unknown Source) at com.crystaldecisions.enterprise.ocaframework.o.a(Unknown Source) at com.crystaldecisions.enterprise.ocaframework.o.a(Unknown Source) at com.crystaldecisions.enterprise.ocaframework.o.a(Unknown Source) at com.crystaldecisions.enterprise.ocaframework.p.a(Unknown Source) at com.crystaldecisions.enterprise.ocaframework.ServiceMgr.getManagedService(Unknown Source) ... 33 more The communication obviously works when logging in.

  • SignalR - No connection could be made because the target machine actively refused it?

    - by user2151460
    Trying to create a Console application that is going to send data to a website. The website is built with Codeiginter framework, if that matters. When i'm running my Console application, i get the error that a connection could not be made, and that the machine refused it. Been watching some tutorials, but most of them are using Hubs etc, which imo i do not need for this simple task?. All i want to do is to send data to the website, one way. Here is my Console application using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using Microsoft.AspNet.SignalR; using Microsoft.AspNet.SignalR.Client; namespace signalrDemo { class Program { static void Main(string[] args) { var connection = new Connection("http://localhost:3000/servers/2"); connection.Received += data => Console.WriteLine(data); connection.Start().ContinueWith(task => { if (task.IsFaulted) { Console.WriteLine("Failed to start: {0}", task.Exception.GetBaseException()); } else { Console.WriteLine("Success! Connected with client connection id {0}", connection.ConnectionId); } }); Console.ReadLine(); } } } And at my website, i have this code $(function () { var connection = $.connection('http://localhost/servers/2'); connection.received(function (data) { $("message").append(data + '<br />'); }); connection.start().done(); }); Thank you.

  • C#: Streaming an Audio file from a Server to a Client

    - by Andreas Grech
    I am currently writing an application that will allow a user to install some form of an application (maybe a Windows Service) that will open a port on it's PC and given a particular destination on the hard disk, will then be able to stream mp3 files. I will then have another application that will connect to the server (being the user's pc) and be able to browse the hosted data by connecting to that PC (remotely ofcourse) given the port, and stream mp3 files from the server to the application I have found some tutorials online but most of them are about File Servers in C# and they download allow you to download a whole file. What I want is to stream an mp3 file so that it starts playing when a certain number of bytes are download (ie, whilst it is being buffered) How do I go about in accomplishing such a task? What I need to know specifically is how to write this application (that I will turn into a Windows Service later on) that will listen on a specified port a stream files, so that I can then access the files by something of the sort: http://<serverip>:65000/acdc/wholelottarosie.mp3 and hopefully be able to stream that file in a WPF MediaPlayer. [Update] I was following this tutorial about building a file server and sending the file from the server to the client. Is what I have to do something of the sort? [Update] Currently reading this post: Play Audio from a Stream using C# and I think it looks very promising as to how I can play streamed files; but I still don't know how I can actually stream the files from the server.

  • MVC2 Client validation with Annotations in View with RenderAction

    - by Olle
    I'm having problem with client side validation on a View that renders a dropdownlist with help of a Html.RenderAction. I have two controllers. SpecieController and CatchController and I've created ViewModels for my views. I want to keep it as DRY as possible and I will most probably need a DropDownList for all Specie elsewhere in the near future. When I create a Catch i need to set a relationship to one specie, I do this with an id that I get from the DropDownList of Species. ViewModels.Catch.Create [Required] public int Length { get; set; } [Required] public int Weight { get; set; } [Required] [Range(1, int.MaxValue)] public int SpecieId { get; set; } ViewModels.Specie.List public DropDownList(IEnumerable<SelectListItem> species) { this.Species = species; } public IEnumerable<SelectListItem> Species { get; private set; } My View for the Catch.Create action uses the ViewModels.Catch.Create as a model. But it feels that I'm missing something in the implemetation. What I want in my head is to connect the selected value in the DropDownList that comes from the RenderAction to my SpecieId. View.Catch.Create <div class="editor-label"> <%: Html.LabelFor(model => model.SpecieId) %> </div> <div class="editor-field"> <%-- Before DRY refactoring, works like I want but not DRY <%: Html.DropDownListFor(model => model.SpecieId, Model.Species) %> --%> <% Html.RenderAction("DropDownList", "Specie"); %> <%: Html.ValidationMessageFor(model => model.SpecieId) %> </div> CatchController.Create [HttpPost] public ActionResult Create(ViewModels.CatchModels.Create myCatch) { if (ModelState.IsValid) { // Can we make this StronglyTyped? int specieId = int.Parse(Request["Species"]); // Save to db Catch newCatch = new Catch(); newCatch.Length = myCatch.Length; newCatch.Weight = myCatch.Weight; newCatch.Specie = SpecieService.GetById(specieId); newCatch.User = UserService.GetUserByUsername(User.Identity.Name); CatchService.Save(newCatch); } This scenario works but not as smooth as i want. ClientSide validation does not work for SpecieId (after i refactored), I see why but don't know how I can ix it. Can I "glue" the DropDownList SelectedValue into myCatch so I don't need to get the value from Request["Species"] Thanks in advance for taking your time on this.

  • JAX-WS client with Axis service

    - by Jon
    I'm relatively new to web services, but I need to integrate a call to an existing service in my application. Ideally, I'd like to use JAX-WS because I'm looking for the simplest, quickest-to-develop solution on my end, and MyEclipse is able to generate a JAX-WS client from a WSDL. Unfortunately, the WSDL I've inherited was built from what appears to be Axis using RPC. Will this still work? When trying to generate the code, I get these errors, and the web searches I've found seem to say that it's the service end that needs to upgrade: <restriction base="soapenc:Array"> <attribute ref="soapenc:arrayType" wsdl:arrayType="impl:MyTypeList[]" /> </restriction> WS-I: (BP2108) An Array declaration uses - restricts or extends - the soapEnc:Array type, or the wsdl:arrayType attribute is used in the type declaration WS-I: (BP2122) A wsdl:types element contained a data type definition that is not an XML schema definition <wsdlsoap:body encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="http://ws.host.com" use="encoded" / WS-I: (BP2406) The use attribute of a soapbind:body, soapbind:fault, soapbind:header and soapbind:headerfault does not have value of "literal".

  • passing timezone from client (GWT) to server (Joda Time)

    - by Caffeine Coma
    I'm using GWT on the client (browser) and Joda Time on the server. I'd like to perform some DB lookups bounded by the day (i.e. 00:00:00 until 23:59:59) that a request comes in, with the time boundaries based on the user's (i.e. browser) timezone. So I have the GWT code do a new java.util.Date() to get the time of the request, and send that to the server. Then I use Joda Time like so: new DateTime(clientDate).toDateMidnight().toDateTime() The trouble of course is that toDateMidnight(), in the absence of a specified TimeZone, will use the system's (i.e. the server's) TimeZone. I've been trying to find a simple way to pass the TimeZone from the browser to the server without much luck. In GWT I can get the GMT offset with: DateTimeFormat.getFormat("Z").fmt(new Date()) which results in something like "-0400". But Joda Time's DateTimeZone.forID() wants strings formatted like "America/New_York", or an integer argument of hours and minutes. Of course I can parse "-0400" into -4 hours and 0 minutes, but I'm wondering if there is not a more straightforward way of doing this.

  • Error in WCF service - Silverlight client communication.

    - by David
    I created a WCF service and I planned to consume this in a Silverlight application. So I created the WCF service in the Website host project. The service is a simple WCF service that only returns a number - something like a Hello World WCF-SL. So after adding a service reference in the silverlight client project to the Service URI, after calling async the service method (by using the generated proxy), I get the following exception in the callback method: An error occurred while trying to make a request to URI 'http://localhost:4566/SLService.svc'. This could be due to attempting to access a service in a cross-domain way without a proper cross-domain policy in place, or a policy that is unsuitable for SOAP services. You may need to contact the owner of the service to publish a cross-domain policy file and to ensure it allows SOAP-related HTTP headers to be sent. This error may also be caused by using internal types in the web service proxy without using the InternalsVisibleToAttribute attribute. Please see the inner exception for more details. I only created a HelloWorld WCF service with nothing else but a simple method that returns a dumb number and it's hosted on my locally. Must I have clientaccesspolicy.xml or crossdomain.xml? I acces my service locally. Every time I create a new simple/dumb WCF-SL solution, I get this error. I use VS2010 and Silverlight 4. I cannot get a simple/dumb WCF-SL solution working locally. Is there something wrong with the configuration? On another machine in the same network, it does work properly, so I assume something is misconfigured. Any thoughts?

  • Best method of achieving bi-directional communication between Apple iPad "clients" and a Windows Ser

    - by user361910
    We are currently starting to build a client-server system which will see 10 or more Apple iPad client devices communicating to a central Windows server over a wireless LAN. We wanted to some existing plumbing (.NET remoting/WCF/web services/etc) that would allow us to implement a reliable, secure solution without having to start at a low level (e.g. sockets) and recreate the wheel. One of the major requirements that complicates this scenario is that unlike a traditional web service, the windows server needs to be able to arbitrarily notify the clients whenever certain events occur -- so it is not a simple request/response scenario like the web. Initially, we were going to use Windows clients, so our plan was to use the full-duplex mode of .NET WCF over HTTP|TCP. But now using the iPad, we don't have any of the WCF infrastructure. So my question is: what is the best way to allow an iPad and a Windows server to (securely) communicate over a LAN, with each device able to initiate communication to the other? Am I stuck writing low-level socket code? Thanks!

  • PHP SoapClient() function returning a single XML string

    - by gjb
    I am having difficulty with the PHP SoapClient() function. The SOAP request is successful, but the response is returned as an object containing a single XML string with the key "any". For example: <?php $params = array('strUsername' => 'Test', 'strPassword' => 'Test'); $client=new SoapClient('http://www.example.com/webservice.asmx?wsdl', array('features' => SOAP_SINGLE_ELEMENT_ARRAYS)); $result = $client->strExampleCall($params); print_r($result); ?> This outputs the following: stdClass Object ( [strExampleCallResult] => stdClass Object ( [any] => <Response xmlns="" release="1.0.0" environment="Production" lang="en-GB"><ApplicationArea><Sender><SenderId>0</SenderId><ReferenceId>0</ReferenceId></Sender><Destination><DestinationId>1</DestinationId></Destination></ApplicationArea><DataArea><Result>1</Result></DataArea></Response> ) ) Subsequently, I cannot access properties of the object as I'd expect to: echo $result->strExampleCallResult->Response->DataArea->Result; Why isn't PHP parsing the SOAP response into properties of the returned object? I am using PHP 5.3.0 and believe the SOAP server is running .NET. Any suggestions will be much appreciated.

  • Sharepoint.OpenDocuments Control Compatible with Forms Authentication?

    - by Richard Collette
    We are using the Sharepoint.OpenDocuments.EditDocument2 ActiveX control and method. The method is being called from JavaScript in an IE6 client on a Windows XP SP3 client (fully patched). The server is running IIS6 on Windows Server 2003 SP1 Fronting the IIS server is Tivoli Access Manager (TAM) which proxies access to the web applications sitting behind it. Similar to forms authentication, it creates a session cookie for authentication purposes, that must be present for the HTTP request to reach the IIS server. In front of TAM is an F5/BigIP load balancer and SSL encryption offloader, which enforces that incoming requests use the HTTPS protocol. What is happening is that HTTP requests issued by this control do not contain any session cookies that were present in the browser. It drops the ASP.NET session cookie, the ASP.NET forms authentication cookie and the TAM cookie Because the TAM cookie is missing the request is redirected to the TAM login page, which then shows up via HTML conversion in Word or Excel. The API documentation at http://msdn.microsoft.com/en-us/library/ms440037.aspx mentions nothing about security or appropriate usage scenarios for this control. Should these controls work in an ASP.Net Forms Authentication scenario or are they only supported with Windows Authentication. If Forms Authentication is supposed to function, how do we get the control to include the necessary session cookies in its requests?

  • Can't send client certificate via SslStream

    - by Jonathan
    I am doing an SSL3 handshake using an SslStream, but, in spite of my best efforts, the SslStream never sends a client certificate on my behalf. Here is the code: SSLConnection = new System.Net.Security.SslStream(SSLInOutStream, false, new System.Net.Security.RemoteCertificateValidationCallback(AlwaysValidRemoteCertificate), new System.Net.Security.LocalCertificateSelectionCallback(ChooseLocalCertificate)); X509CertificateCollection CC = new X509CertificateCollection(); CC.Add(Org.BouncyCastle.Security.DotNetUtilities.ToX509Certificate(MyLocalCertificate)); SSLConnection.AuthenticateAsClient("test", CC, System.Security.Authentication.SslProtocols.Ssl3, false); and then I have AlwaysValidRemoteCertificate just returning true, and ChooseLocalCertificate returning the zeroth element of the array. The code probably looks a little weird because the project is a little weird, but I think that is beside the point here. The SSL handshake completes. The issue is that instead of sending a certificate message on my behalf (in the handshake process), with the ASN.1 encoded certificate (MyLocalCertificate), the SslStream sends an SSL alert number 41 (no certificate) and then carries on. I know this from packet sniffing. After the handshake is completed, the SslStream marks IsAuthenticated as true, IsMutuallyAuthenticated as false, and its LocalCertificate member is null. I feel like I'm probably missing something pretty obvious here, so any ideas would be appreciated. I am a novice with SSL, and this project is off the beaten path, so I am kind of at a loss. P.S. 1: My ChooseLocalCertificate routine is called twice during the handshake, and returns a valid (as far as I can tell), non-null certificate both times. P.S. 2: SSLInOutStream is my own class, not a NetworkStream. Like I said, though, the handshake proceeds mostly normally, so I doubt this is the culprit... but who knows?

  • MessageSecurityException: The security header element 'Timestamp' with the '' id must be signed

    - by NiklasN
    I'm asking the same question here that I've already asked on msdn forums http://social.msdn.microsoft.com/Forums/en-US/netfxnetcom/thread/70f40a4c-8399-4629-9bfc-146524334daf I'm consuming a (most likely Java based) Web Service with I have absolutely no access to modify. It won't be modified even though I would ask them (it's a nation wide system). I've written the client with WCF. Here's some code: CustomBinding binding = new CustomBinding(); AsymmetricSecurityBindingElement element = SecurityBindingElement.CreateMutualCertificateDuplexBindingElement(MessageSecurityVersion.WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10); element.AllowSerializedSigningTokenOnReply = true; element.SetKeyDerivation(false); element.IncludeTimestamp = true; element.KeyEntropyMode = SecurityKeyEntropyMode.ClientEntropy; element.MessageProtectionOrder = System.ServiceModel.Security.MessageProtectionOrder.SignBeforeEncrypt; element.LocalClientSettings.IdentityVerifier = new CustomIdentityVerifier(); element.SecurityHeaderLayout = SecurityHeaderLayout.Lax; element.IncludeTimestamp = false; binding.Elements.Add(element); binding.Elements.Add(new TextMessageEncodingBindingElement(MessageVersion.Soap11, Encoding.UTF8)); binding.Elements.Add(new HttpsTransportBindingElement()); EndpointAddress address = new EndpointAddress(new Uri("url")); ChannelFactory<MyPortTypeChannel> factory = new ChannelFactory<MyPortTypeChannel>(binding, address); ClientCredentials credentials = factory.Endpoint.Behaviors.Find<ClientCredentials>(); credentials.ClientCertificate.Certificate = myClientCert; credentials.ServiceCertificate.DefaultCertificate = myServiceCert; credentials.ServiceCertificate.Authentication.CertificateValidationMode = X509CertificateValidationMode.None; service = factory.CreateChannel(); After this every request done to the service fails in client side (I can confirm my request is accepted by the service and a sane response is being returned) I always get the following exception MessageSecurityException: The security header element 'Timestamp' with the '' id must be signed. By looking at trace I can see that in the response there really is a timestamp element, but in the security section there is only a signature for body. Can I somehow make WCF to ingore the fact Timestamp isn't signed?

  • Steps in creating a web service using Axis2 - The client code

    - by zengr
    I am trying to create a web service, my tools of trade are: ** Axis2, Eclipse, Tomcat, Ant ** I need to create a web service from Code, i.e. Write a basic java class which will have the methods to be declared in the WSDL. Then use java2WSDL.sh to create my WSDL. So, is this approach correct: Write my Java class with actual business logic package packageNamel; public class Hello{ public void World(String name) { SOP("Hello" + name); } } Now, when I pass this Hello.java to java2WSDL.sh, this will give me the WSDL. Finally, I will write the services.xml file, and create the Hello.aar with following dir structure: Hello.aar packageName Hello.class META-INF services.xml MANIFEST.MF Hello.WSDL Now, I assume, my service will be deployed when I put the aar in tomcat1/webapps/axis2/WEB-INF/services But, here comes my problem, HOW DO I ACCESS THE METHOD World(String name)???!!, i.e. I am clueless about the client code! Please enlighten me on making a very basic web service and calling the method. The above described 3 steps might be wrong. It's a community wiki, feel free to edit. Thanks

  • Why ClassCastException on JMS ConnectionFactory lookup in JNDI?

    - by Derek Mahar
    What might be the cause of the following ClassCastException in a standalone JMS client application when it attempts to retrieve a connection factory from the JNDI provider? Exception in thread "main" java.lang.ClassCastException: javax.naming.Reference cannot be cast to javax.jms.ConnectionFactory Here is an abbreviated version of the JMS client that includes only its start() and stop() methods. The exception occurs on the first line in method start() which attempts to retrieve the connection factory from the JNDI provider, a remote LDAP server. The JMS connection factory and destination objects are on a remote JMS server. class JmsClient { private ConnectionFactory connectionFactory; private Connection connection; private Session session; private MessageConsumer consumer; private Topic topic; public void stop() throws JMSException { consumer.close(); session.close(); connection.close(); } public void start(Context context, String connectionFactoryName, String topicName) throws NamingException, JMSException { // ClassCastException occurs when retrieving connection factory. connectionFactory = (ConnectionFactory) context.lookup(connectionFactoryName); connection = connectionFactory.createConnection("username","password"); session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE); topic = (Topic) context.lookup(topicName); consumer = session.createConsumer(topic); connection.start(); } private static Context getInitialContext() throws NamingException, IOException { String filename = "context.properties"; Properties props = new Properties(); props.load(new FileInputStream(filename)); return new InitialContext(props); } }

  • Does JAXWS client make difference between an empty collection and a null collection value as returne

    - by snowflake
    Since JAX-WS rely on JAXB, and since I observed the code that unpack the XML bean in JAX-B Reference Implementation, I guess the difference is not made and that a JAXWS client always return an empty collection, even the webservice result was a null element: public T startPacking(BeanT bean, Accessor<BeanT, T> acc) throws AccessorException { T collection = acc.get(bean); if(collection==null) { collection = ClassFactory.create(implClass); if(!acc.isAdapted()) acc.set(bean,collection); } collection.clear(); return collection; } I agree that for best interoperability service contracts should be non ambiguous and avoid such differences, but it seems that the JAX-WS service I'm invoking (hosted on a Jboss server with Jbossws implementation) is returning as expected either null either empty collection (tested with SoapUI). I used for my test code generated by wsimport. Return element is defined as: @XmlElement(name = "return", nillable = true) protected List<String> _return; I even tested to change the Response class getReturn method from : public List<String> getReturn() { if (_return == null) { _return = new ArrayList<String>(); } return this._return; } to public List<String> getReturn() { return this._return; } but without success. Any helpful information/comment regarding this problem is welcome !

  • What's the fastest way to bulk insert a lot of data in SQL Server (C# client)

    - by Andrew
    I am hitting some performance bottlenecks with my C# client inserting bulk data into a SQL Server 2005 database and I'm looking for ways in which to speed up the process. I am already using the SqlClient.SqlBulkCopy (which is based on TDS) to speed up the data transfer across the wire which helped a lot, but I'm still looking for more. I have a simple table that looks like this: CREATE TABLE [BulkData]( [ContainerId] [int] NOT NULL, [BinId] [smallint] NOT NULL, [Sequence] [smallint] NOT NULL, [ItemId] [int] NOT NULL, [Left] [smallint] NOT NULL, [Top] [smallint] NOT NULL, [Right] [smallint] NOT NULL, [Bottom] [smallint] NOT NULL, CONSTRAINT [PKBulkData] PRIMARY KEY CLUSTERED ( [ContainerIdId] ASC, [BinId] ASC, [Sequence] ASC )) I'm inserting data in chunks that average about 300 rows where ContainerId and BinId are constant in each chunk and the Sequence value is 0-n and the values are pre-sorted based on the primary key. The %Disk time performance counter spends a lot of time at 100% so it is clear that disk IO is the main issue but the speeds I'm getting are several orders of magnitude below a raw file copy. Does it help any if I: Drop the Primary key while I am doing the inserting and recreate it later Do inserts into a temporary table with the same schema and periodically transfer them into the main table to keep the size of the table where insertions are happening small Anything else? -- Based on the responses I have gotten, let me clarify a little bit: Portman: I'm using a clustered index because when the data is all imported I will need to access data sequentially in that order. I don't particularly need the index to be there while importing the data. Is there any advantage to having a nonclustered PK index while doing the inserts as opposed to dropping the constraint entirely for import? Chopeen: The data is being generated remotely on many other machines (my SQL server can only handle about 10 currently, but I would love to be able to add more). It's not practical to run the entire process on the local machine because it would then have to process 50 times as much input data to generate the output. Jason: I am not doing any concurrent queries against the table during the import process, I will try dropping the primary key and see if that helps. ~ Andrew

  • Exposing C# COM server events to Delphi client applications

    - by hectorsosajr
    My question is very similar to these two: http://stackoverflow.com/questions/1140984/c-component-events http://stackoverflow.com/questions/1638372/c-writing-a-com-server-events-not-firing-on-client However, what worked for them is not working for me. The type library file, does not have any hints of events definitions, so Delphi doesn't see it. The class works fine for other C# applications, as you would expect. COM Server tools: Visual Studio 2010 .NET 4.0 Delphi applications: Delphi 2010 Delphi 7 Here's a simplified version of the code: /// <summary> /// Call has arrived delegate. /// </summary> [ComVisible(false)] public delegate void CallArrived(object sender, string callData); /// <summary> /// Interface to expose SimpleAgent events to COM /// </summary> [ComVisible(true)] [GuidAttribute("1FFBFF09-3AF0-4F06-998D-7F4B6CB978DD")] [InterfaceType(ComInterfaceType.InterfaceIsIDispatch)] public interface IAgentEvents { ///<summary> /// Handles incoming calls from the predictive manager. ///</summary> ///<param name="sender">The class that initiated this event</param> ///<param name="callData">The data associated with the incoming call.</param> [DispId(1)] void OnCallArrived(object sender, string callData); } /// <summary> /// Represents the agent side of the system. This is usually related to UI interactions. /// </summary> [ComVisible(true)] [GuidAttribute("EF00685F-1C14-4D05-9EFA-538B3137D86C")] [ClassInterface(ClassInterfaceType.None)] [ComSourceInterfaces(typeof(IAgentEvents))] public class SimpleAgent { /// <summary> /// Occurs when a call arrives. /// </summary> public event CallArrived OnCallArrived; public SimpleAgent() {} public string AgentName { get; set; } public string CurrentPhoneNumber { get; set; } public void FireOffCall() { if (OnCallArrived != null) { OnCallArrived(this, "555-123-4567"); } } } The type library file has the definitions for the properties and methods, but no events are visible. I even opened the type library in Delphi's viewer to make sure. The Delphi app can see and use any property, methods, and functions just fine. It just doesn't see the events. I would appreciate any pointers or articles to read. Thanks!

  • Can't connect to HTTPS using X509 client certificate

    - by wows
    Hi - I'm new to cryptography and I'm a bit stuck: I'm trying to connect (from my development environment) to a web service using HTTPS. The web service requires a client certificate - which I think I've installed correctly. They have supplied me with a .PFX file. In Windows 7, I double clicked the file to install it into my Current User - Personal certificate store. I then exported a X509 Base-64 encoded .cer file from the certificate entry in the store. It didn't have a private key associate with it. Then, in my app, I'm attempting to connect to the service like this: var certificate = X509Certificate.CreateFromCertFile("xyz.cer")); var serviceUrl = "https://xyz"; var request = (HttpWebRequest) WebRequest.Create(serviceUrl); request.ClientCertificates.Add(certificate); request.Method = WebRequestMethods.Http.Post; request.ContentType = "application/x-www-form-urlencoded"; I get a 502 Connection failed when I connect. Is there anything you can see wrong with this method? Our production environment seems to work with a similar configuration, but it's running Windows Server 2003. Thanks!

  • Creating a REST client API using Reactive Extensions (Rx)

    - by Jonas Follesø
    I'm trying to get my head around the right use cases for Reactive Extensions (Rx). The examples that keeps coming up are UI events (drag and drop, drawing), and suggestions that Rx is suitable for asynchronous applications/operations such as web service calls. I'm working on an application where I need to write a tiny client API for a REST service. I need to call four REST end-points, three to get some reference data (Airports, Airlines, and Statuses), and the fourth is the main service that will give you flight times for a given airport. I have created classes exposing the three reference data services, and the methods look something like this: public Observable<Airport> GetAirports() public Observable<Airline> GetAirlines() public Observable<Status> GetStatuses() public Observable<Flights> GetFlights(string airport) In my GetFlights method I want each Flight to hold a reference the Airport it's departing from, and the Airline operating the flight. To do that I need the data from GetAirports and GetAirlines to be available. My initial thinking was something like this: Write a Rx Query that will Subscribe on the three reference services (Airports, Airlines and Statuses) Add results into a Dictionary (airline code and Airline object) When all three GetAirports, GetAirlines and GetStatuses are complete, then return the GetFlights IObservable. Is this a reasonable scenario for Rx? I'm developing on the Windows Phone 7, so I'm not sure if there are major differences in the Rx implementations across the different platforms.

  • Client Web Browser Behavior When Handling 301 Redirect

    - by Jon Swanson
    The RFC seems to suggest that the client should permanently cache the response: http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html 10.3.2 301 Moved Permanently The requested resource has been assigned a new permanent URI and any future references to this resource SHOULD use one of the returned URIs. Clients with link editing capabilities ought to automatically re-link references to the Request-URI to one or more of the new references returned by the server, where possible. This response is cacheable unless indicated otherwise. The new permanent URI SHOULD be given by the Location field in the response. Unless the request method was HEAD, the entity of the response SHOULD contain a short hypertext note with a hyperlink to the new URI(s). If the 301 status code is received in response to a request other than GET or HEAD, the user agent MUST NOT automatically redirect the request unless it can be confirmed by the user, since this might change the conditions under which the request was issued. Note: When automatically redirecting a POST request after receiving a 301 status code, some existing HTTP/1.0 user agents will erroneously change it into a GET request. I'm having a hard time finding concrete browser documentation for any major browser that states how they handle these. I've started digging through the source code of firefox, but quickly got lost. Is the following scenario true for which (if any) browsers, and is there definitive documentation for either Firefox or IE that states as much?: First Time Around: 1.1: User enters link to site A, or clicks on a link directed at Site A 1.2: Browser interprets link at Site A, first time, no cache. Sends GET to Site A. 1.2: Site A responds with 301 Redirect to Site B 1.3: Browser sends GET to Site B. Any Subsequent Times Around: 2.2: User clicks on a link directed at Site A 2.2: Browser sees that, due to a past 301 redirect, Site A should now be Site B. 2.3: Without initiating any request whatsoever at Site A, browser initiates GET at Site B.

  • Anyone know exactly which JMS messages will be redelivered in CLIENT_ACKNOWLEDGE mode if the client

    - by user360612
    The spec says "Acknowledging a consumed message automatically acknowledges the receipt of all messages that have been delivered by its session" - but what I need to know is what it means by 'delivered'. For example, if I call consumer.receive() 6 times, and then call .acknowledge on the 3rd message - is it (a) just the first 3 messages that are ack'd, or (b) all 6? I'm really hoping it's option a, i.e. messages after the one you called acknowledge on WILL be redelivered, otherwise it's hard to see how you could prevent message lost in the event of my receiver process crashing before I've had a chance to persist and acknowledge the messages. But the spec is worded such that it's not clear. I get the impression the authors of the JMS spec considered broker failure, but didn't spend too long thinking about how to protect against client failure :o( Anyway, I've been able to test with SonicMQ and found that it implements (a), i.e. messages 'received' later than the message you call .ack on DO get redelivered in the event of a crash, but I'd love to know how other people read the standard, and if anyone knows how any other providers have implemented CLIENT_ACKNOWLEDGE? (i.e. what the 'de facto' standard is) Thanks Ben

  • Problem in using a second call to send() in C

    - by Paulo Victor
    Hello. Right now I'm working in a simple Server that receives from client a code referring to a certain operation. The server receives this data and send back the signal that it's waiting for the proper data. /*Server Side*/ if (codigoOperacao == 0) { printf("A escolha foi 0\n"); int bytesSent = SOCKET_ERROR; char sendBuff[1080] = "0"; /*Here "send" returns an error msgm while trying to send back the signal*/ bytesSent = send(socketEscuta, sendBuff, 1080, 0); if (bytesSent == SOCKET_ERROR) { printf("Erro ao enviar"); return 0; } else { printf("Bytes enviados : %d\n", bytesSent); char structDesmontada[1080] = ""; bytesRecv = recebeMensagem(socketEscuta, structDesmontada); printf("structDesmontada : %s", structDesmontada); } } Following here is the client code responsible for sending the operation code and receiving the signal char sendMsg[1080] = "0"; char recvMsg[1080] = ""; bytesSent = send(socketCliente, sendMsg, sizeof(sendMsg), 0); printf("Enviei o codigo (%d)\n", bytesSent); /*Here the program blocks in a infinite loop since the server never send anything*/ while (bytesRecv == SOCKET_ERROR) { bytesRecv = recv(socketCliente, recvMsg, 1080, 0); if (bytesRecv > 0) { printf("Recebeu\n"); } Why this is happening only in the second attempt to send some data? Because the first call to send() works fine. Hope someone can help!! Thnks

  • Android - Basic CRUD (REST/RPC client) to remote server

    - by bsreekanth
    There are lot of discussion about REST client implementation in android, based on the talk at GoogleIO 2010, by Virgil Dobjanschi. My requirement may not necessarily involved, as I have some freedom to choose the configuration. I only target tablets configuration changes can be prevented if no other easy way (fix at Landscape mode etc) I am trying to achieve. Basic CRUD operation to my server (JSON RPC/ REST). Basically mimic an ajax request from android app (no webview, need native app) Based on the above mentioned talk, and some reading I see these options. Implement any of the 3 mentioned in the Google IO talk Especially, the last pattern may be more suitable as I don't care much of caching. But not sure how "real time" is sync implementation. Use HTTP request in AsyncTask. Simplest, but need to avoid re-sending request during change in device configuration (orientation change etc). Even if I fix at one orientation, recreation of activity still happens. So need to handle it elegantly. Use service to handle http request. So far, it say use service for long ruiing request. Not sure whether it is a good approach for simple GET/POST/PUt requests. Please share your experience on what could be the best way.
