  • which asp net hosting site allows to listen on differnt port than 80 and uses .net 4?

    - by ijjo
    i'm trying to take advantage of html 5 web sockets in .NET and the easiest way appears to do something like this guy does: http://www.codeproject.com/KB/webservices/c_sharp_web_socket_server.aspx?msg=3485900#xx3485900xx i've already tested this myself and it works great, but there are a few problems if i try to deploy this to my hosting site (discountasp.net). basically i am not allowed to open up a port on 8080 and listen on it. i then tried to figure out a way to listen non port 80 with IIS as well, but using the HTTPListener runs into sercurity issues as well that doesn't seem like will help since i can't mess with this stuff on the hosting site server either: http://stackoverflow.com/questions/169904/can-i-listen-on-a-port-using-httplistener-or-other-net-code-on-vista-without-r so to make my life easier, i think i need to find a hosting site that simply allows me to open up a socket on port 8080 and listen on it. anyone know of one? or anyone know of a workaround (besides sniffing ALL the traffic on port 80)?

  • WebHttpBinding: Log all errors to service logfile

    - by W van Noort
    I have a self-hosted WCF service that uses a WebHttpBinding. In the implementation of the service, all exceptions are caught and a appropriate message is returned to the caller. All exceptions are also logged to the service logfile. catch (Exception ex) { _log.Error("Error posting message", ex); WebOperationContext.Current.OutgoingResponse.StatusCode = HttpStatusCode.InternalServerError; return string.Format("{0}:error={1}", (int)HttpStatusCode.InternalServerError, ex.Message); } However, some situations are intercepted by the WCF framework. e.g.: when the client sends a message that exceeds the configured quotum, i never get an entry in my log file. In fact, i only found this, by adding this to the config file, and inspecting the generated trace file. <system.diagnostics> <sources> <source name="System.ServiceModel" switchValue="Information, ActivityTracing" propagateActivity="true"> <listeners> <add name="xml" /> </listeners> </source> <source name="CardSpace"> <listeners> <add name="xml" /> </listeners> </source> <source name="System.IO.Log"> <listeners> <add name="xml" /> </listeners> </source> <source name="System.Runtime.Serialization"> <listeners> <add name="xml" /> </listeners> </source> <source name="System.IdentityModel"> <listeners> <add name="xml" /> </listeners> </source> </sources> <sharedListeners> <add name="xml" type="System.Diagnostics.XmlWriterTraceListener" initializeData="c:\test\Traces.svclog" /> </sharedListeners> Is there a way to get these kind of errors visible in my own logfile?

    - by user171523
    I am in the process of evaluating a Service Broker with SQL noticiation for my project. My requirements is User places a order from System A and it will update Order Table. As soon as order is place i need to notify the System B. I have done a quick POC with Trigger , Service Broker and SQLNotificaiton ADO.NET. It is working as i expected. What i would like to know the group A) What are the best practices i need to follow for this? B) What are disadvantages with the above approach if any? C) Are there any disadvantes of using the Triggers? If so what are those for above approach? The order table will get order from System A like 1000 to 1500 every day. I also would like to know the performance of above approach.

  • How to use OSGi getServiceReference() right

    - by Jens
    Hello, I am new to OSGi and came across several examples about OSGi services. For example: import org.osgi.framework.*; import org.osgi.service.log.*; public class MyActivator implements BundleActivator { public void start(BundleContext context) throws Exception { ServiceReference logRef = context.getServiceReference(LogService.class.getName()); } } My question is, why do you use getServiceReference(LogService.class.getName()) instead of getServiceReference("LogService") If you use LogService.class.getName() you have to import the Interface. This also means that you have to import the package org.osgi.services.log in your MANIFEST.MF. Isn't that completely counterproductive if you want to reduce dependencies to push loose coupling? As far as I know one advantage of services is that the service consumer doesn't have to know the service publisher. But if you have to import one specific Interface you clearly have to know who's providing it. By only using a string like "LogService" you would not have to know that the Interface is provided by org.osgi.services.log.LogService. What am I missing here?

  • Certificate Information from WCF Service using Transport security mode

    - by Langdon
    Is there any way to pull information about which client certificate was used inside of my web service method when using <security mode="Transport>? I sifted through OperationContext.Current but couldn't find anything obvious. My server configuration is as follows: <basicHttpBinding> <binding name="SecuredBasicBindingCert"> <security mode="Transport"> <message clientCredentialType="Certificate" /> </security> </binding> </basicHttpBinding> I'm working with a third party pub/sub system who is unfortunately using DataPower for authentication. It seems like if I'm using WCF with this configuration, then I'm unable to glean any information about the caller (since no credentials are actually sent). I somehow need to be able to figure out whose making calls to my service without changing my configuration or asking them to change their payload.

  • How to use SerialPort SerialDataReceived help

    - by devnet247
    Hi Not sure how to handle SerialPort DataReceived. Scenario I have an application that communicate with a device and this device returns a status .This happens in different stages EG public enum ActionState { Started, InProgress, Completed etc... } Now if I were to use the DataReceivedEventHandler how can I tell what Method is executing? eg Action1 or Action2 etc...? I also want to include some sort of timeout when getting back stuff from device. Any example or advice? public ActionState Action1 { serialPort.write(myData); string result=serialPort.ReadExisting()); //convertTo ActionState and return return ConvertToActionState(result); } public ActionState Action2 { serialPort.write(myData); string result=serialPort.ReadExisting()); //convertTo ActionState and return return ConvertToActionState(result); } private void port_DataReceived(object sender, SerialDataReceivedEventArgs e) { //How can I use this to detect which method is firing and set the actionState Enum accordingly? } private ActionState(string result) { if(result==1) return ActionState.Started; else if (result==2) return ActionState.Completed etc... }

  • C# WCF client configuration for X509 secured web service over https

    - by Kam
    Hi guys I been pulling my hair out for the past few days trying to connect to a web service using .Net 3.5 and WCF (have also tried using WSE 3.0) without much luck. The web service is hosted by a 3rd party and we can access via https. They also make use of X509 certificates for security, to sign the message. I've been given some basic info and am able to connect and test the service using SOAP UI 3.5 without any problems, so we know that this is not the issue. Just trying to get it done in code! I've added the X509 certificate into the certificate store using the mmc snap-in, and using tracing and logging i can see that the message is being signed, just unable to see which part i have got wrong. Any healp GREATLY appreciated :) I've been given an offline WSDL file, which I have imported in as a service reference is VS 2008. My calling code looks like so, simple enough: ServicePointManager.ServerCertificateValidationCallback = delegate(object sender,X509Certificate certificate,X509Chain chain, SslPolicyErrors sslErrors) { return true; }; GatewayClient gateway = new GatewayClient(); CheckStatusResponse response = gateway.CheckLineStatus(); And my config looks like so: <basicHttpBinding> <binding name="Gateway_1.0" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> <security mode="TransportWithMessageCredential"> <transport clientCredentialType="None" proxyCredentialType="None" realm="" /> <message clientCredentialType="Certificate" algorithmSuite="Default" /> </security> </binding> </basicHttpBinding> <customBinding> <binding name="Gateway_1"> <security authenticationMode="CertificateOverTransport" includeTimestamp="true" messageProtectionOrder="SignBeforeEncrypt"> <localClientSettings maxClockSkew="12:00:00" replayWindow="12:00:00" sessionKeyRolloverInterval="12:00:00" timestampValidityDuration="12:00:00" /> <localServiceSettings maxClockSkew="12:00:00" sessionKeyRolloverInterval="12:00:00" timestampValidityDuration="12:00:00" /> <secureConversationBootstrap /> </security> <textMessageEncoding messageVersion="Soap11" /> <sslStreamSecurity requireClientCertificate="true" /> <httpsTransport hostNameComparisonMode="WeakWildcard" /> </binding> </customBinding> <wsHttpBinding> <binding name="Gateway_1" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true" allowCookies="false"> <security mode="TransportWithMessageCredential"> <message clientCredentialType="Certificate" negotiateServiceCredential="false" establishSecurityContext="true" /> </security> </binding> </wsHttpBinding> </bindings> <client> <endpoint address="https://XXX.XX.XXX.XX/SOAP" behaviorConfiguration="ClientCertificateBehavior" binding="wsHttpBinding" bindingConfiguration="Gateway_1" contract="B2BService.Gateway" name="Gateway_1_HTTPSPort"> <identity> <dns value="ext.test.com" /> </identity> </endpoint> </client> <behaviors> <endpointBehaviors> <behavior name="ClientCertificateBehavior"> <clientCredentials> <clientCertificate findValue="mycertificate.com" storeLocation="CurrentUser" storeName="Root" x509FindType="FindBySubjectName" /> <serviceCertificate> <authentication certificateValidationMode="PeerOrChainTrust" /> </serviceCertificate> </clientCredentials> </behavior> </endpointBehaviors> </behaviors> </system.serviceModel> Regardless of which config I use, the code fails for one reason or another, causing internal server errors, Error processing message for security, Undefined 'badEncoding' resource property, or expected http URI given https, and a few other! Been going round and round a bit, and I am sure it is very simple once the cofig is set :( I'm sure I've missed loads out, let me know if seeing the SOAP UI generated envelope and the currect WCF generated envelope will help. many thanks.

  • Loading XML from Web Service

    - by Lukasz
    I am connecting to a web service to get some data back out as xml. The connection works fine and it returns the xml data from the service. var remoteURL = EveApiUrl; var postData = string.Format("userID={0}&apikey={1}&characterID={2}", UserId, ApiKey, CharacterId); var request = (HttpWebRequest)WebRequest.Create(remoteURL); request.Method = "POST"; request.ContentLength = postData.Length; request.ContentType = "application/x-www-form-urlencoded"; // Setup a stream to write the HTTP "POST" data var WebEncoding = new ASCIIEncoding(); var byte1 = WebEncoding.GetBytes(postData); var newStream = request.GetRequestStream(); newStream.Write(byte1, 0, byte1.Length); newStream.Close(); var response = (HttpWebResponse)request.GetResponse(); var receiveStream = response.GetResponseStream(); var readStream = new StreamReader(receiveStream, Encoding.UTF8); var webdata = readStream.ReadToEnd(); Console.WriteLine(webdata); This prints out the xml that comes from the service. I can also save the xml as an xml file like so; TextWriter writer = new StreamWriter(@"C:\Projects\TrainingSkills.xml"); writer.WriteLine(webdata); writer.Close(); Now I can load the file as an XDocument to perform queries on it like this; var data = XDocument.Load(@"C:\Projects\TrainingSkills.xml"); What my problem is that I don't want to save the file and then load it back again. When I try to load directly from the stream I get an exception, Illegal characters in path. I don't know what is going on, if I can load the same xml as a text file why can't I load it as a stream. The xml is like this; <?xml version='1.0' encoding='UTF-8'?> <eveapi version="2"> <currentTime>2010-04-28 17:58:27</currentTime> <result> <currentTQTime offset="1">2010-04-28 17:58:28</currentTQTime> <trainingEndTime>2010-04-29 02:48:59</trainingEndTime> <trainingStartTime>2010-04-28 00:56:42</trainingStartTime> <trainingTypeID>3386</trainingTypeID> <trainingStartSP>8000</trainingStartSP> <trainingDestinationSP>45255</trainingDestinationSP> <trainingToLevel>4</trainingToLevel> <skillInTraining>1</skillInTraining> </result> <cachedUntil>2010-04-28 18:58:27</cachedUntil> </eveapi> Thanks for your help!

  • Capturing SOAP requests to an ASP.NET ASMX web service

    - by pcampbell
    Consider the requirement to log incoming SOAP requests to an ASP.NET ASMX web service. The task is to capture the raw XML being sent to the web service. The incoming message needs to be logged for debug inspection. The application already has its own logging library in use, so the ideal usage would be something like this: //string or XML, it doesn't matter. string incomingSoapRequest = GetSoapRequest(); Logger.LogMessage(incomingSoapRequest); Are there any easy solutions to capture the raw XML of the incoming SOAP requests? Which events would you handle to get access to this object and the relevant properties?

  • Spring Web Service Client Tutorial or Example Required

    Hello All... I need to jump into the Spring Web Service Project, in that I required to implement the Spring Web Service's Client Only.. So, I have already gone through with Spring's Client Reference Document. So, I got the idea of required classes for the implementation of Client. But my problem is like I have done some googling, but didn't get any proper example of both Client and Server from that I can implement one sample for my client. So, if anybody gives me some link or tutorial for proper example from that I can learn my client side implementation would be greatly appreciated. Thanks in advance...

  • Linux: How to find all serial devices (ttyS, ttyUSB and others)?

    - by Thomas Tempelmann
    What is the proper way to get a list of all available serial ports/devices on a Linux system? In other words, when I iterate over all devices in /dev/, how do I tell which ones are serial ports in the classic way, i.e. those usually supporting baud rates and RTS/CTS flow control? The solution would be coded in C. I ask because I am using a 3rd party library that does this clearly wrong: It appears to only iterate over /dev/ttyS*. The problem is that there are, for instance, serial ports over USB (provided by USB-RS232 adapters), and those are listed under /dev/ttyUSB*. And reading the Serial-HOWTO at Linux.org, I get the idea that there'll be other name spaces as well, as time comes. So I need to find the official way to detect serial devices. Problem is that there appears none documented, or I can't find it. I imagine one way would be to open all files from /dev/tty* and call a specific ioctl() on them that is only available on serial devices. Would that be a good solution, though?

    I have a frustrating problem with an asp.net mvc view containing the Microsoft Chart control. When I request the view containing the control I get the following error. Service Unavailable HTTP Error 503. The service is unavailable. When I run the project under the visual studio 2008 dev server it works fine. When I deploy the project to the staging server I get the error. To make this even more frustrating when I deploy to a different site on the same server under a virtual directory it works. I also get no error messages in the event log or elmah when this happens. Has anyone else encountered this? What did you do to resolve it?

  • Is that a RESTFUL MVC Web Service?

    - by vsj
    I am aware of Web Services and WCF but I have generic question with services.I have a ASP.NET MVC Application which does some basic functionality. I just have a controller in which I am passing it the records and serializing the information to XML using XML Serializer. Then I return this information to the browser and it displays me the XML i got from the Controller Action. So I get the XML representation of my Class(Database Object) in XML and I am to give the URL of this application to the client and access and pull the information. Is this a Service then? I mean in the end all the Clients need is the Xml representation through services also right? I am not that experienced and probably being very silly but please help me out...if I provide xml this way to the client is that a Service ? Or is there something I need to undersatand here?.

I have a windows service: protected override void OnCustomCommand(int command) { if (command == 1) { foreach (Process traceProcess in Process.GetProcessesByName("notepad.exe")) { traceProcess.Kill(); } } } when I do this: ServiceController sc = new ServiceController("ProjectManager"); if (sc != null) sc.ExecuteCommand(1); From a windows forms it works, but not from a web page, I get access denied on sc.ExecuteCommand. What's the best way for a web page to talk to a service?
