Pure C++: Invoking Generic or Function Templates

  

As I promised last time, in this month's column I'll walk through the process of defining and invoking a generic or template function under C++\CLI. A function template or a generic function begins with the template or generic keyword followed by its parameter list.

Need help in reading Soap request and response on invoking WCF client assembly

  
Hi All,   I'm new to WCF and i'm using .Net 3.5. I have created a library from the proxy class generated through svcutil. I'm able to succesfully invoke service methods. I was wondering how to capture the request and response soap xmls so that i could render it on browser. If you have any code piece for this kind of problem please share it with me. Regards, Rahul

Error while invoking wcf service and running its methods

  
Failed to invoke the service. Possible causes: The service is offline or inaccessible; the client-side configuration does not match the proxy; the existing proxy is invalid. Refer to the stack trace for more detail. You can try to recover by starting a new proxy, restoring to default configuration, or refreshing the service.    I am using a wcf service with some methods in it called by some layers wherein i am putting all my business logic.While invoking the service from wcftestclient  and when running few methods i am getting this error . I am getting output for some methods in the same service but for some other methods i am getting this error . I am using LINQ in the methods.    My solution has number of projects .For running the service ,i am right clicking on the project and viewing in the browser as i cannot build whole solution as i have few errors in some unit test projects.       As i am getting output for some methods ,this is definetly not about starting the service .  

Invoking custom WCF service throws an Impersonation error from SQL

  
I've written a custom WCF service and hosted it in SharePoint. Accessing the MEX endpoint works fine. However, when I try to invoke the WCF service from my client code, I get the following error: 'A transport-level error has occurred when sending the request to the server. (provider: Shared Memory Provider, error: 0 - Either a required impersonation level was not provided, or the provided impersonation level is invalid.)'. This exception gets thrown even before my WCF service gets invoked. Attaching a debugger, I see the following stack trace associated with the exception: 00000000`0c2dd7d0 000007fe`e7589b95 System_Data_ni!System.Data.SqlClient.SqlConnection.OnError(System.Data.SqlClient.SqlException, Boolean)+0xd4 00000000`0c2dd810 000007fe`e7b7cd3b System_Data_ni!System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(System.Data.SqlClient.TdsParserStateObject)+0xf5 00000000`0c2dd870 000007fe`e758c4ee System_Data_ni!System.Data.SqlClient.TdsParserStateObject.WriteSni()+0x5f77ab 00000000`0c2dd8f0 000007fe`e758bf29 System_Data_ni!System.Data.SqlClient.TdsParserStateObject.ExecuteFlush()+0xae 00000000`0c2dd950 000007fe`e757a1c7 System_Data_ni!System.Data.SqlClient.TdsParser.TdsExecuteRPC(System.Data.SqlClient._SqlRPC[], Int32, Boolean, System.Data.Sql.SqlNotificationRequest, System.Data.SqlClient.TdsParserStateObject, Boolean)+0x1189 00000000`0c2ddbf

Help - error invoking WCF on Apache Web Server

  

I'm attempting to host a WCF service and Silverlight client on Apache Web Server, and I'm running into some issues. The Silverlight client is a simple web page that calls a WCF service, but I'm having problems:

  • I can successfully access my .svc file through a browser locally using localhost, but if I try to use the system IP address locally instead, I get an error of  No protocol binding matches the given address 'http://192.168.100.75/WCFDuplex/PubSubService.svc'. Protocol bindings are configured at the Site level in IIS or WAS configuration.
  • If in the codebehind of my Silverlight page I hardcode the URL to the WCF service to use localhost and I locally access the Silverlight web page using localhost in the URL, the Silverlight page is able to successfully interact with the WCF web service. This is good, so nothing to fix here. However, if I access the Silverlight web page locally using the IP address in the URL and in the codebehind of my Silverlight page I hardcode the URL to the WCF service to use localhost, I get a NotFound error when the Silverlight page attempts to interact with the web service.

Are there any specific steps to make a WCF service hostable on Apache Web Server? Should I be able to invoke a WCF web service from Silverlight on an Apache Web Server? I've setup both clientaccesspolicy.

Manually Invoking a __doPostBack Call

  

I have a web forms page with a button that involkes a __doPostBack callback to the page.  I would like to invoke this manually - by "manually" I mean from outside the webpage, for example by using wget.  Is there a way or an example of the best way to do this, please?

Invoking a web method fails with 'The underlying connection was closed: Unable to connect to the re

  

Hi all,

i am currently challenging a problem that suddenly started to happen in my production environment when invoking a WS method from a windows-service .NET app.

The windows service is waiting for requests incoming through MQ, unwraps these requests from an "MQ XML packet" and redirects these requests to the web service. This web service has only one web method, which is kind of "main entry point" for the underlying backend application.

This monday approx. 30% of attempts to invoke that web method are failing with message: The underlying connection was closed: Unable to connect to the remote server.

Couple of soap errors on invoking a webmethod in ASPNet web services

  

Hi there!!

I am consuming an ASP.Net webservice from a simple .Net application by
adding a web reference. However when I invoke the web method, we see a
couple of soap error entries in the application event log with the
result that the http request is not successfully completed.

We even tried to invoke the web method directly from the asmx page in
IE providing in the required parameters. We still get the same errors.

Please note this problem is intermittent and does not happend
everytime.

The following are the event log entries:

Soap error: XML Parser failed at linenumber 0, lineposition 0, reason
is: The download of the specified resource has failed.
Soap error: Soap client is not initialized.
Soap error: One of the parameters supplied is invalid..
Soap error: Loading of the WSDL file failed.

Sometimes we get a little different kind of event log entries as given
below:

aspnet_wp.exe  (PID: 2228) stopped unexpectedly.
Soap error: One of the parameters supplied is invalid..

Soap error: Loading of the WSDL file failed.

Soap error: XML Parser failed at linenumber 0, lineposition 0, reason
is:
The system cannot locate the object specified.

We fail to understand as to where is the problem. We can easily browse
to the wsdl file successful

Invoking Java Axis Webservice Issue

  

Hi Experts,

Here's my problem:

I have an asp.net app that invokes a java/axis based webservice through a wsdl file provided by my customer.

But, as i had no access to this webservice at the dev time, i've created a fake .net based webservice, with the same methods, returning some valid data, so i'd be able to test the integration interface.

The problem is, when i add the service reference on my app, pointing to my fake webservice (.net), it's class has a certain name, and when i point it to my customer's wsdl file, it's class has a different name.

Generated class name when i add the service reference by:
    - .NET fake webservice = "TransferenciaEndpointSoapClient"
    - wsdl file of the java/axis webservice = "TransferenciaEndpointClient"

I want the class i've created in my fake webservice to keep the same name of the wsdl, when i add the service reference on my app.

I tried to add a "web reference" instead of a "service reference", but it did not work. I also tried to change the name of the class on the "Reference.cs" file, it works on my environment, but it doesn't when i put the generated bin on my customer's environment. I'd like to sol

invoking other workflow from main workflow dynamically

  

 Been doing research for a whlie now and while I suspect I passed right by the answer, it wasn't obvious -- so, figured a direct question is best

I have a situation where I have multiple vendors I do business with and the list can change.  I'd like to be able to create a new workflow for each vendor where I want to support custom steps.  Let's say it is placing an order, and I have a default process that involves manual work.

I envisioned a file (say XML) where I can have a name which represents the workflow I want to invoke.

In my main workflow I wanted to have a parallel activity that sent a message to all of the vendor workflows (on my machine) and waited for them all to finish before moving on.

So, my questions

1. What do I need to do to send a message to this vendor specific workflow?  I have it's name and I can build out a URI based on the name.  In other words, how can I make this work

2.  Does this vendor workflow just have to reply to the receive to indicate "I'm done" to the main workflow

Thanks in advance for pointers, etc.
