Calling Web Service Asynch

Posted By:      Posted Date: May 22, 2011    Points: 0   Category :ADO.Net

We have a .Net Windows Service that creates a dataset and sends it to an Asynchronous Web Service method.  This all works great, the Web Service code fires and processes the dataset.  

This Windows Service is scheduled to perform this function once a day.

The first time the Windows Service makes the call to the Web Service, everything works as designed, without any errors.  Then, when the Windows Service makes subsequent calls to the same Web Service method, nothing happens.  The Windows Service completes its routine, but the Web Service never starts running its code.

When we restart the Windows Service, then the call to the Web Service method completes just fine, until subsequent calls are made.

If we call the corresponding Synchronous method, it all works fine and we do not experience the issue described.

What am I missing?


Web Service Method:

        [WebMethod(EnableSession = true)]

        public void RefreshProducts(Guid scheduledTaskId, DataSet productDataSet, String productName, String userName, String password)


            ValidateLicenseAndUser(userName, password);

VS2005 calling VS2010 asmx service returns empty string


Anyone have any experience with this?

We are using VS 2005 for the front end, and vs 2010 for the web services part (asmx), not wcf yet.


Web service works just like the vs2005 when run locally, no problems.


Connecting to it from a test app returns an empty string. Connecting to a 2005 app doesn't!

Anyone run into this before or have a suggestion? Surely vs 2005 can connect to web services from a later version?

Calling an asp.net web service from jQuery

As I have post it in earlier post that jQuery is one of most popular JavaScript library in the world amongst web developers Lets take a example calling ASP.NET web service with jQuery . You will see at the end of the example that how easy it is to call a web service from the jQuery. Let's create a simple Hello World web service. Go to your project right click->Add -> New Item and select web service and add a web service like following.   Now modify the code of web service like following. [WebService(Namespace = "http://tempuri.org/")][WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)][System.ComponentModel.ToolboxItem(false)]// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. [System.Web.Script.Services.ScriptService]public class HelloWorld : System.Web.Services.WebService{ [WebMethod] public string PrintMessage() { return "Hello World..This is from webservice"; }} Here please make sure that [System.Web.Script.Services.ScriptService] is un commented because this attribute is responsible for allowing web service to be called by Client side scripts. Now to call this  web service from jquery we have to include jQuery Js like following. I am already having in my project so i don't need to include in project just need to add script tag like following. <script type="t

calling a web service on a remote server from an ASPX page

hi, I want to call a web service on a remote server. I've done "add web reference" in my project, and VS2005 has created the .discomap and .WSDL in the App_Web_Reference folder. When I try add the namespace representing the web server (the name I created when I added the web reference) by "using XXXXX;" the code does not compile because XXXXX is not defined. Have I missed any steps? thanks, -me

While calling Web service gets exception "The request failed with HTTP status 401: Unauthorized"

Hi All, I created a ASP.NET web service, which was hosted on default visual studioserver, and on excecution of webservice it run .exe file which in turn update xml file. Now i hosted this webservice on IIS 6.0 server, and when i run the service, itfails to execute the exe.When i run it on debug mode, i never get any exception.Code...public string HelloWorld()    {        Process myProcess = new Process();        try        {            myProcess.StartInfo.UseShellExecute = false;            // You can start any process,             myProcess.StartInfo.FileName = @"E:\Projects\some.exe";            myProcess.StartInfo.CreateNoWindow = true;            myProcess.Start();            myProcess.Close();            myProcess.Dispose();            return "Suceess";         }&n

calling a web service on a remote server from a ASPX page (web site project VS2005)

HI,I am maintaining a web site project in VS2005 and have to call a new web service on a remote server. I've done add web reference, and created the .wsdl and .discomap files in the app_webReference folder.  When I try to create a object representing the web service in the code ( wsnamespace.serviceName ws = new wsnamespce.serviceName(); ) the code wouldn't compile.The web site project is already calling other web services. When I right click on the type representing the web service and "go to definition" it takes me to a proxy class (derived from of course SoapHttpClientProtocol) in the metadata. I think this is what's missing for  the new web service i'm trying to call. Have I missed any steps?Thanks in advance.-me

Error calling WCF service that is returning list.".Debugging resource strings are unavailable ......

Ok.this is just making me frustrated... Here is step by step of what I am trying to do (& not able to) 1. I am calling WCF service hosted in a SharePoint 2010 site from a silverlight app in same domain (So no cross doman I guess). 2. I use Linq to Sharepoint for querying the DB. 3. I am having a list "machines" in Sharepoint 2010 that is having a lookup column from Other list called "part" 4. My WCF method GetAllMachines() works perfectly well when it skips the lookup column "partname" & returns List of type machineitem. 5. But problem occurs when I add machineitemobject.parts.partsname in my Linq to Sharepoint query . My service gives the error not found Async_ExceptionOccurred] Arguments: Debugging resource strings are unavailable." 6. Note that return type of my Method is List<machinesitem> 7. The point to note here is that I use SPMETAL tool to generate the LINQ class that maps the lists . So When I try to query the lookup column it tries to add List item of the type class & that is what causing the error. Is it because I am not using datacontract in my service (but it returns the strings & all private members of machines list e.g. name,title etc) Is it making the attribute Serialisable will solve the error ??? I am kind of lost in it ...Plss help!!   Thanks

Service Operation - Get proper data when browsing the service, but not when calling the service from

Hello, I recently implemented a service operation in an attempt to pass some filter parameters to a data service (a user guid and an organization, actually, for impersonation of a user on the service's call to the application). I successfully added the service operation to the data service, and I can browse the service and see the data filtered as I expected. However, when I call the service operation from the Silverlight client, I don't get any results, even though I should. Am I missing something? Code below if it's helpful. Thanks! Service Operation Definition: [WebGet] public IEnumerable<opportunity> filteredopps(string userid, string org) { /*Define the connection with the impersonated user*/ CrmConnection crmc = CrmConnection.Parse("Authentication Type=Passport; Server=https://" + org + ".crm.dynamics.com/" + org + "; User ID=myuser; Password=mypassword; Device ID=mydeviceid; Device Password=mydevicepassword"); crmc.ImpersonatedUser = new Guid(userid); var crmOnline = new DataContext(crmc); List<opportunity> uplist = new List<opportunity>(); crmOnline.UsingService(service => { var query = from o in crmOnline.opportunityopportunities select o; foreach (opportunity thisopp in query) { uplist.Add(thisopp);

Workflow Service not calling workflow in another project

I have a windows workflow service 4.0 that calls a workflow located in another project (i.e. another assembly). I have created a project reference in my workflow service project to the workflow in the other assembly. I have set a breakpoint in the workflow service receive activity and this breakpoint is hit. Next I step into the next activity which is an activity located in another project and the debugger does not work. Also the other workflow is sending an email.  It appears that the other workflow is not being called because I never receive an email from the workflow in the other project.   Any help is greatly appreciated.

Duplex communication and calling clients from outside the hosted service

Hey,   I am currently building an interface between two applications: One that hosts a WCF service and receives external input (e.g. from a sensory system) and another which subscribes to updates sent by the first.   It is quite easy to call back to the client if I create a ServiceHost and provide it with an instance of my service (using ServiceHost.SingletonInstance). However, if I use a PerSession instance mode, how is it possible to call the clients when I receive an updated from the external sensory system?   Thank you for your time!   Cheers, Till

Calling one endpoint from another endpoint in the same service

Hi, I have a WCF service host Im hosting in IIS that defines a few services and one of those services has a number of endpoints. The endpoints that belong to the same service are there to let me specify different contracts and they all use the same binding and behaviour. For the most part it works fine until a specific situation occurs: The service gets stuck when one of the endpoints tries to make a call to another endpoint in the same service. Consider the following example: <service behaviorConfiguration="GeneralServiceBehavior" name="Base"> <endpoint address="/Addresses" binding="wsHttpBinding" bindingConfiguration="wsHttpBindingConfig" contract="CommonObjects.IAddresss" /> <endpoint address="/Attachments" binding="wsHttpBinding" bindingConfiguration="wsHttpBindingConfig" contract="CommonObjects.IAttachments" /> </service> In the example above if a call is made from IAttachments implementor back to this service to access the IAddress endpoint I get stuck in what seems to be a deadlock until I get a timeout on the calling thread and then I see the call come through to the IAddress endpoint, but at that point its already too late as the channel is closed. I have looked at the InstanceContext and ConcurrencyMode. This particular servic

problem with calling soap service written (most probably in java)

Why do I get a 401 error when calling a WCF service from a web part?

I have a SharePoint 2010 web part and WCF service deployed to a web application using Kerberos authentication. The service was developed based on the walkthrough from MSDN with the only difference that ClientCredentialType = HttpClientCredentialType.Windows so that Kerberos is used. The web application is being reverse-published through ISA. However we've never had an issue with this before. We've also disabled the loopback check on the server. When the web part calls the service, a 401 error occurs with the following exception message: The HTTP request is unauthorized with client authentication scheme 'Negotiate'. The authentication header received from the server was 'NTLM'. I configured Fiddler on the web application running the web part and found that both Kerberos and NTLM authentication headers are being returned: HTTP/1.1 401 Unauthorized Server: Microsoft-IIS/7.5 SPRequestGuid: 541e724c-85a7-47a0-b045-827e1c50793c WWW-Authenticate: Negotiate oXsweaADCgEBoQsGCSqGSIL3EgECAqJlBGNgYQYJKoZIhvcSAQICAwB+UjBQoAMCAQWhAwIBHqQRGA8yMDEwMDkxNDA1MjY1NlqlBQIDDgespgMCASmpDBsKREVDUy5MT0NBTKoXMBWgAwIBAaEOMAwbCnNwX3dlYmFwcDE= WWW-Authenticate: NTLM X-Powered-By: ASP.NET MicrosoftSharePointTeamServices: Date: Tue, 14 Sep 2010 05:26:56 GMT Content-Length: 0 Proxy-Support: Session-Based-Authentication Why then is the Kerberos authentication not a

Calling a Web Service Method Asynchronously does not work in Console Application

I have a web service that has a CreateReport method that generates a report based on the specified criteria. When I call this method Synchronously using a Windows Application or Console Application, the call works fine and the report is created. When I call this method ASynchronously (CreateReportASync) using Windows Application the report is created. When I call this method ASynchronously (CreateReportASync) using Console Application the web service does not even get the call.  I am using VS2005 and .Net Framework 2.0.  So the proxy is automatically created with the Async methods.  I am not really interested the result of the method call, so I do not add a Callback Delegate.  

change the PHP page with WCF service on Servers only, without chnging code on the calling client sid



I need to change the PHP page with WCF service, but the problem is that many of our clients are sending(usig POST) large stream data like binary files to our PHP website, now we are upgrading our system and moving towards wcf services,

The problem is that we want our clients to only change URL, and do not need to change any code in their calling mechanism or no need to create proxy on their cliend side. We simply change php to wcf services on our Servers only. Our clients are using .net 2.0 client application. Is there any way to do this. or Is this possible ?

One thing which I get from internet is use Rest based wcf services.

Have anybody some example or idea to accomplish my task.


moss07 calling wcf service - caller not auth by service


I've got a moss2007 web part that is calling a wcf service. I can call the service fine outside of moss and it works fine. when i convert the user control into a web part and make the call I get:

Slow performance of WCF service calling singleton (which calls COM+!)


WCF Service call routing to COM+ application.
netTCPBinding, throttling set pretty high.

[ServiceBehavior(InstanceContextMode = InstanceContextMode.Single, ConcurrencyMode=ConcurrencyMode.Multiple)] 

Service has two methods, one simply returns the string was input, the other calls the COM+ component and FOR TESTING returns the string "success" for every call. Therefore, both methods return a simple string.

Client starts 20 threads, each calling the WCF Service twice. (NOTE: A "first call" is made to prime the singleton service and also the COM+ component)
