  • C# Inhieriting DataContract Derived Types

    - by dsjohnston
    I've given a fair read through msdn:datacontracts and I cannot find a out why the following does not work. So what is wrong here? Why isn't ExtendedCanadianAddress recognized by the datacontract serializer? Type 'XYZ.ExtendedCanadianAddress' with data contract name 'CanadianAddress:http://tempuri.org/Common/Types' is not expected. Add any types not known statically to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding them to the list of known types passed to DataContractSerializer. Given: namespace ABC { [KnownType(typeof(Address))] public abstract class Z { //stuff //method that adds all types() in namespace to self } [KnownType(typeof(CanadianAddress))] [DataContact(Name = "Address", Namespace = "http://tempuri.org/Types")] public class Address : Z {} [DataContract(Name = "CanadianAddress", Namespace = "http://tempuri.org/Types")] public class CanadianAddress : Address {} } namespace XYZ { [KnownType(typeof(ExtendedCanadianAddress)) [DataContact(Name = "Address", Namespace = "http://tempuri.org/Types")] public class ExtendedAddress : Address { //this serializes just fine } [DataContact(Name = "CanadianAddress", Namespace = "http://tempuri.org/Types")] public class ExtendedCanadianAddress : CanadianAddress { //will NOT serialize } }

  • OAuth Consumer request for token from ServiceProvider returns InternalServerError

    - by chridam
    I'm playing around with DevDefined.OAuth - an OAuth consumer and provider implementation for .Net http://code.google.com/p/devdefined-tools/wiki/OAuth and on launching the ExampleConsumerSite project after configuring the service endpoints on my IIS 7 web server, I'm receiving the following error: Description: An unhandled exception occurred during the execution of the current web request.

  • WebSharingAppDemo-CEProviderEndToEnd Queries peerProvider for NeedsScope before any files are batche

    - by Don
    I'm building an application based on the WebSharingAppDemo-CEProviderEndToEnd. When I deploy the server portion on a server, the code gives the error "The path is not valid. Check the directory for the database." during the call to NeedsScope() in the CeWebSyncService.cs file. Obviously the server can't access the client's sdf but what is supposed to happen to make this work? The app uses batching to send the data and the batches have to be marshalled across to the temp directory but this problem is occurring before any files have been batched over. There is nothing for the server to look at to determine whether the peerProivider needs scope. What am I missing? public bool NeedsScope() { Log("NeedsSchema: {0}", this.peerProvider.Connection.ConnectionString); SqlCeSyncScopeProvisioning prov = new SqlCeSyncScopeProvisioning(); return !prov.ScopeExists(this.peerProvider.ScopeName, (SqlCeConnection)this.peerProvider.Connection); }

  • Webservices on iPhone - wsdl2objc - Sample Code?

    - by markmcgookin
    I have recently downloaded the most recent build of this awesome tool WSDL2OBJC from google code here: http://code.google.com/p/wsdl2objc/ After a bit of tweaking and downloading the latest version of the trunk from the svn repo I got a version that created the code for a WSDL I am using and compiles great and actually installs on my phone! However, I'm not doing anything with it yet, because I am not really sure how to. There is very little in the way of sample code on the site, and there is a sample file in the project if you download it, but again it is very complicated and there are no real bits of documentation. Has anyone managed to successfully use this stuff? It seems SOOO powerful and useful but from a look around the Internet, no one knows how to use it. We (all) would love someone who has figured it out to post a simple project or detailed walk-through of implementing this so we can put the code that lots of people have worked hard on to good use. If anyone has found a blog entry or has this information it would be great to see! I am totally stuck... with no errors. I would love to know how to use this now that it's all compiled successfully!

  • RIA Services Localization, where to place Resource Files

    - by kmacmahon
    I have the following Solution: SomeProject.Ria (non Silverlight code) SomeProject.Ria.Silverlight (Silverlight light code, namespace is still SomeProject.Ria) SomeProject.Ria.MyServices (RIA Services Domain Service) SomeProject.Ria.MyServices.Proxies (RIA Services Silverlight Generated Code) SomeProject.Shell (Silverlight Applicaiton) SomeProject.Web (Web Application) I would like to use Resource Files for my Annotations on the meta data class in SomeProject.Ria.MyServices. The format for that appears to be: [Required(AllowEmptyStrings=false,ErrorMessageResourceName="ThisFieldIsRequired", ErrorMessageResourceType(MyResource))] Which project does MyResource belong in? (Assuming that someday I need to support other culture files). Also the use of the string in here really seems to breed room for error, is it possible to do something like this and still achieve localization, or does this just get compiled into the meta data? If not, how can I get round the resource name being a string? [Required(AllowEmptyStrings=false,ErrorMessage=MyResources.RequiredMessage)]

  • How do I Pass Parameter in Ajax Url?

    - by Nimit Joshi
    I have developed a service which is running successfully. Following is my service code: namespace WcfService1 { [ServiceContract] public interface IService1 { [OperationContract] [WebInvoke(Method="GET", ResponseFormat = WebMessageFormat.Json, BodyStyle=WebMessageBodyStyle.Wrapped, UriTemplate="/display/{a}/{b}")] string Display(string a, string b); } } My Service: namespace WcfService1 { public class Service1 : IService1 { public string Display(string a, string b) { int ab = Convert.ToInt32(a); int bc = Convert.ToInt32(b); int cb = ab + bc; return cb.ToString(); } } } How do i call this with the help of ajax url? I have tried out the following code but it is not working. <script type="text/javascript"> $(document).ready(function () { $('#BtnRegister').click(function () { debugger; var No1 = document.getElementById('TxtFirstNumber').value; var No2 = document.getElementById('TxtSecondNumber').value; $.ajax({ cache: false, type: "GET", async: false, url: "http://localhost:22727/Service1.svc/Display", data: 'a=' +No1+'&b='+No2, contentType: "application/json; charset=ytf-8", dataType: "json", processData: true, success: function (result) { alert("data"); }, error: function (xhr, textStatus, errorThrown) { alert(textStatus + ':' + errorThrown); } }); }); }); </script>

  • ChannelFactory don't have an address on the endpoint, why?

    - by Maxim
    When I create a new instance of a ChannelFactory: var factory = new ChannelFactory<IMyService>(); and that I create a new channel, I have an exception saying that the address of the Endpoint is null. My configuration inside my web.config is as mentioned and everything is as it is supposed to be (especially the address of the endpoint). If I create a new MyServiceClientBase, it loads all the configuration from my channel factory: var factoryWithClientBase = new MyServiceClientBase().ChannelFactory; Console.WriteLine(factoryWithClientBase.Endpoint.Address); //output the configuration inside the web.config var factoryWithChannelFactory = new ChannelFactory<IMyService>(); Console.WriteLine(factoryWithChannelFactory.Endpoint.Address); //output nothing (null) Why?

  • Problem with MessageContract, Generic return types and clientside naming

    - by Soeteman
    I'm building a web service which uses MessageContracts, because I want to add custom fields to my SOAP header. In a previous topic, I learned that a composite response has to be wrapped. For this purpose, I devised a generic ResponseWrapper class. [MessageContract(WrapperNamespace = "http://mynamespace.com", WrapperName="WrapperOf{0}")] public class ResponseWrapper<T> { [MessageBodyMember(Namespace = "http://mynamespace.com")] public T Response { get; set; } } I made a ServiceResult base class, defined as follows: [MessageContract(WrapperNamespace = "http://mynamespace.com")] public class ServiceResult { [MessageBodyMember] public bool Status { get; set; } [MessageBodyMember] public string Message { get; set; } [MessageBodyMember] public string Description { get; set; } } To be able to include the request context in the response, I use a derived class of ServiceResult, which uses generics: [MessageContract(WrapperNamespace = "http://mynamespace.com", WrapperName = "ServiceResultOf{0}")] public class ServiceResult<TRequest> : ServiceResult { [MessageBodyMember] public TRequest Request { get; set; } } This is used in the following way [OperationContract()] ResponseWrapper<ServiceResult<HCCertificateRequest>> OrderHealthCertificate(RequestContext<HCCertificateRequest> context); I expected my client code to be generated as ServiceResultOfHCCertificateRequest OrderHealthCertificate(RequestContextOfHCCertificateRequest context); Instead, I get the following: ServiceResultOfHCCertificateRequestzSOTD_SSj OrderHealthCertificate(CompType1 c1, CompType2 c2, HCCertificateRequest context); CompType1 and CompType2 are properties of the RequestContext class. The problem is that a hash is added to the end of ServiceResultOfHCCertificateRequestzSOTD_SSj. How do I need define my generic return types in order for the client type to be generated as expected (without the hash)?

  • Web Services vs Persistent Sockets

    - by dsquires
    I plan on doing a little benchmarking around this question, myself. But I thought it would be good to get some initial feedback from "the community". Has anyone out there done any analysis regarding the pros and cons of these two technologies? My thoughts: Opening and closing TCP/IP connections for web service calls is relatively expensive compared to persistent connections. Dealing with intermittent connection errors and state, etc... would be easier with a web service based framework. You don't see World of Warcraft using web services. One question that I can't seem to find much of answer for anywhere (even on here)... are the limits on the # of persistent connections a single network card can support, etc?

  • Secure Password Storage and Transfer

    - by Andras Zoltan
    I'm developing a new user store for my organisation and am now tackling password storage. The concepts of salting, HMAC etc are all fine with me - and want to store the users' passwords either salted and hashed, HMAC hashed, or HMAC salted and hashed - not sure what the best way will be - but in theory it won't matter as it will be able to change over time if required. I want to have an XML & JSON service that can act as a Security Token Service for client-side apps. I've already developed one for another system, which requires that the client double-encrypts a clear-text password using SHA1 first and then HMACSHA1 using a 128 unique key (or nonce) supplied by the server for that session only. I'd like to repeat this technique for the new system - upgrading the algo to SHA256 (chosen since implementations are readily available for all aforementioned platforms - and it's much stronger than SHA1) - but there is a problem. If I'm storing the password as a salted hash in the user-store, the client will need to be sent that salt in order to construct the correct hash before being HMACd with the unique session key. This would completely go against the point of using a salt in the first place. Equally, if I don't use salt for password storage, but instead use HMAC, it's still the same problem. At the moment, the only solution I can see is to use naked SHA256 hashing for the password in the user store, so that I can then use this as a starting point on both the server and the client for a more secure salted/hmacd password transfer for the web service. This still leaves the user store vulnerable to a dictionary attack were it ever to be accessed; and however unlikely that might be - assuming it will never happen simply doesn't sit well with me. Greatly appreciate any input.

If I unload the project and reload it again, I get this message, even on an empty Silverlight project (no changes made to the project file). "error : A project with that name is already opened in the solution." The solution has only 2 projects: the host (web) and the silverlight one. Any help is appreciated :) UPDATE: It only happens if I give the Silverlight project the same name as the solution.

  • The remote server returned an error: (400) Bad Request - uploading less 2MB file size?

    - by fiberOptics
    The file succeed to upload when it is 2KB or lower in size. The main reason why I use streaming is to be able to upload file up to at least 1 GB. But when I try to upload file with less 1MB size, I get bad request. It is my first time to deal with downloading and uploading process, so I can't easily find the cause of error. Testing part: private void button24_Click(object sender, EventArgs e) { try { OpenFileDialog openfile = new OpenFileDialog(); if (openfile.ShowDialog() == System.Windows.Forms.DialogResult.OK) { string port = "3445"; byte[] fileStream; using (FileStream fs = new FileStream(openfile.FileName, FileMode.Open, FileAccess.Read, FileShare.Read)) { fileStream = new byte[fs.Length]; fs.Read(fileStream, 0, (int)fs.Length); fs.Close(); fs.Dispose(); } string baseAddress = "http://localhost:" + port + "/File/AddStream?fileID=9"; HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(baseAddress); request.Method = "POST"; request.ContentType = "text/plain"; //request.ContentType = "application/octet-stream"; Stream serverStream = request.GetRequestStream(); serverStream.Write(fileStream, 0, fileStream.Length); serverStream.Close(); using (HttpWebResponse response = request.GetResponse() as HttpWebResponse) { int statusCode = (int)response.StatusCode; StreamReader reader = new StreamReader(response.GetResponseStream()); } } } catch (Exception ex) { MessageBox.Show(ex.Message); } } Service: [WebInvoke(UriTemplate = "AddStream?fileID={fileID}", Method = "POST", BodyStyle = WebMessageBodyStyle.Bare)] public bool AddStream(long fileID, System.IO.Stream fileStream) { ClasslLogic.FileComponent svc = new ClasslLogic.FileComponent(); return svc.AddStream(fileID, fileStream); } Server code for streaming: namespace ClasslLogic { public class StreamObject : IStreamObject { public bool UploadFile(string filename, Stream fileStream) { try { FileStream fileToupload = new FileStream(filename, FileMode.Create); byte[] bytearray = new byte[10000]; int bytesRead, totalBytesRead = 0; do { bytesRead = fileStream.Read(bytearray, 0, bytearray.Length); totalBytesRead += bytesRead; } while (bytesRead > 0); fileToupload.Write(bytearray, 0, bytearray.Length); fileToupload.Close(); fileToupload.Dispose(); } catch (Exception ex) { throw new Exception(ex.Message); } return true; } } } Web config: <system.serviceModel> <bindings> <basicHttpBinding> <binding> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="2097152" maxBytesPerRead="4096" maxNameTableCharCount="2097152" /> <security mode="None" /> </binding> <binding name="ClassLogicBasicTransfer" closeTimeout="00:05:00" openTimeout="00:05:00" receiveTimeout="00:15:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferPoolSize="67108864" maxReceivedMessageSize="67108864" messageEncoding="Mtom" textEncoding="utf-8" useDefaultWebProxy="true"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="67108864" maxBytesPerRead="4096" maxNameTableCharCount="67108864" /> <security mode="None"> <transport clientCredentialType="None" proxyCredentialType="None" realm="" /> <message clientCredentialType="UserName" algorithmSuite="Default" /> </security> </binding> <binding name="BaseLogicWSHTTP"> <security mode="None" /> </binding> <binding name="BaseLogicWSHTTPSec" /> </basicHttpBinding> </bindings> <behaviors> <serviceBehaviors> <behavior> <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment --> <serviceMetadata httpGetEnabled="true" /> <!-- To receive exception details in faults for debugging purposes, set the value below to true.

One more thing is this, whether I run the service and passing a stream or not, the created file always contain this thing. How could I remove the "NUL" data? Thanks in advance. Edit public bool UploadFile(string filename, Stream fileStream) { try { FileStream fileToupload = new FileStream(filename, FileMode.Create); byte[] bytearray = new byte[10000]; int bytesRead, totalBytesRead = 0; do { bytesRead = fileStream.Read(bytearray, totalBytesRead, bytearray.Length - totalBytesRead); totalBytesRead += bytesRead; } while (bytesRead > 0); fileToupload.Write(bytearray, 0, totalBytesRead); fileToupload.Close(); fileToupload.Dispose(); } catch (Exception ex) { throw new Exception(ex.Message); } return true; }

  • Transparent proxying - how to pass socket to local server without modification?

    - by Luca Farber
    Hello, I have a program that listens on port 443 and then redirects to either an SSH or HTTPS local server depending on the detected protocol. The program does this by connecting to the local server and proxying all data back and forth through its own process. However, this causes the originating host on the local servers to be logged as localhost. Is there any way to pass the socket directly to the local server process (rather than just making a new TCP connection) so that the parameters of sockaddr_in (or sockaddr_in6) will be retained? Platform for this is Linux.

  • PostSharp when using DataContractSerializer?

    - by Dan Bryant
    I have an Aspect that implements INotifyPropertyChanged on a class. The aspect includes the following: [OnLocationSetValueAdvice, MethodPointcut("SelectProperties")] public void OnPropertySet(LocationInterceptionArgs args) { var currentValue = args.GetCurrentValue(); bool alreadyEqual = (currentValue == args.Value); // Call the setter args.ProceedSetValue(); // Invoke method OnPropertyChanged (ours, the base one, or the overridden one). if (!alreadyEqual) OnPropertyChangedMethod.Invoke(args.Location.Name); } This works fine when I instantiate the class normally, but I run into problems when I deserialize the class using a DataContractSerializer. This bypasses the constructor, which I'm guessing interferes with the way that PostSharp sets itself up. This ends up causing a NullReferenceException in an intercepted property setter, but before it has called the custom OnPropertySet, so I'm guessing it interferes with setting up the LocationInterceptionArgs. Has anyone else encountered this problem? Is there a way I can work around it? I did some more research and discovered I can fix the issue by doing this: [OnDeserializing] private void OnDeserializing(StreamingContext context) { AspectUtilities.InitializeCurrentAspects(); } I thought, okay, that's not too bad, so I tried to do this in my Aspect: private IEnumerable<MethodInfo> SelectDeserializing(Type type) { return type.GetMethods(BindingFlags.Instance | BindingFlags.NonPublic | BindingFlags.Public).Where( t => t.IsDefined(typeof (OnDeserializingAttribute), false)); } [OnMethodEntryAdvice, MethodPointcut("SelectDeserializing")] public void OnMethodEntry(MethodExecutionArgs args) { AspectUtilities.InitializeCurrentAspects(); } Unfortunately, even though it intercepts the method properly, it doesn't work. I'm thinking the call to InitializeCurrentAspects isn't getting transformed properly, since it's now inside the Aspect rather than directly inside the aspect-enhanced class. Is there a way I can cleanly automate this so that I don't have to worry about calling this on every class that I want to have the Aspect?
