C# - Consume A SOAP Web Service Without Relying On The App.config?

Sep 13, 2010

I'm building a .NET component that will call an external web service. I used the "Add Service Reference" dialog to add the web service to my component, which generates the code needed to consume the service and adds the settings to the app.config file.I'm testing the component by adding a reference to its DLL from a Console application and calling the appropriate method that creates a new instance of the web service: ... = new MyServiceSoapClient(). However, when I do this, I get the following exception:

InvalidOperationException

Could not find default endpoint element that references contract 'MyServicesSoap' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element.This makes sense since the app.config isn't being brought over with the component's DLL. How can I call the web service without having to rely on the settings in the App.Config?

Mar 23, 2012

I'm currently working on a VB. Net web service calling another web service running in the mainframe. I was provided with the WSDL file and I generated a proxy class using wsdl.exe. Upon attempting to invoke the method of the mainframe web service using the proxy class, I encountered an exception saying "Conversion from SOAP failed" coming from a line of code in the generated proxy class.

Soap Client Not Working On PHP Soap Server?

Dec 27, 2011

I wrote a soap service in PHP using nusoap. It works fine with the test client I wrote in PHP, however, our customer wrote his client in vb.net and it is not working. There are no errors that I see, but the service is not parsing his requests properly.

I am letting nusoap generate the WSDL, and it looks fine. If I compare a message that I send in to one of his messages, I do see a few differences in the envelope, but I'm not sure if the problem is on my end or his.

.net - WCF Service Hosted In A Managed Windows Service Connect Using A WCF Service Application

Jul 14, 2011

i have a Windows service that is hosting a WCF service through net.tcp and this is working great. I have also created a WCF service application. I am trying to add the net.tcp service reference to the service application. Then I add it to the GAC that goes ok but if I try to RegAsm the WCF service application to allow it to be called from Server.CreateObject I get the error:

Warning: Type library exporter encountered a type that derives from a
generic class and is not marked as
[ClassInterface(ClassInterfaceType.None)]. Class interfaces cannot be
exposed for such types. Consider marking the type with
[ClassInterface(ClassInterfaceType.None)] and exposing an explicit
interface as the default interface to COM using the
ComDefaultInterface attribute.

It does not work. I have tried to call it through a class library but this does not work either as the end point is not set correctly.

SOAP With Attachments In .NET?

May 31, 2012

I need to use a web service that was provided to me and that uses SOAP with attachments as a means of communication. It also uses WS-Security 1.0 as a form of authencation (user and pass in plain text).I will be working on VB.NET and my experience with web services is very slim, and goes as far as creating a WCF web service, adding the service reference in another project thus creating a proxy class and using the methods.I have searched the internet and found that there is no native support for SwA in VB.NET, is this correct?

Complex Types In SOAP With VB 6.0

Sep 15, 2009

I am currently working on a project, which purpose is to call a webservice through a VB script. VB is by far not my first language and I simply reach the point where I do not know how to go on from here.

I have a Webservice descriped in a WSDL document that defines a service that takes a complex type as parameter and returns such one as answer.

The complex type is basically just a string that is wrapped inside a class object. So what i did was to create a new class module and added a public variable to it. I created a new instance of this class, gave it for the purpose of testing a value and tried to call the webservice. Everything goes well untill i reach the call to the webservice, where the program throws an exception that says:

"Class does not support automation or does not support expected interface"

My first thought was that the initialization of the object might have gone wrong but i am quite able to set and get the values on it. So i have to assume that the object is okay. I know that the url to the WSDL document is correct, due to the fact that I can call the document via the browser and it will throw an exception of "wrong type" when i feed the soap method with a primitive.

With out luck I browsed several pages on the net to find a clue what this could. So now i wanted to give this forum a shot.

You should know that i am not able to alter the WSDL file. I have to go with the way it is. In addition am supposed to stick to VB 6.0.

I used a Form in VB to make the call to the webservice.

Here is the call procedure:

Private Sub Command1_Click()
On Error GoTo ErrorHandler
Dim tS

VS 2008 WebService SOAP?

Jan 25, 2010

It's the first time that i'm trying to use SOAP, i don't know how to make the request, I know the URL where the operation it's located, and i know the name of the operation, and i know the expected xml document schema. I have read in msdn about Microsoft.Web.Services2.SoapEnvelope, but i'm missing something...

The function structure it's something like:
<normal soap nodes until body>
<NameOfTheFunction xmlns="http://tempuri.org/">
<Var1>Value1</Var1>
<Var2>Value1</Var2>

Do i need the webrequest class? or the soap class can do all the job?

.net - Response Validation For Soap Client?

Dec 30, 2011

This is related to my question at the below link, however posting on a seperate thread as needed some direction on the error handling part.soap request client to webservice using vb.net

How/Where can i get the error "response validation not conforming to wsdl and schema" in my vb.net webservice client. I checked the response using the validate response option, within soapui tool. Is there any way to generate the logs related to this, in .net client?There was no exception in my .net client, except the response object was blank, even though i could see the response xml in the trace log.

The below line invokes the webservice. After the excution, tracelog has the request and response xml, however my objresp(response object) is empty. In soapui, i validated the response, it was not conforming to schema.objresponsehead = objProxy.myoperation(objreqheader, objrequest, objresp)

.net - Soap Request/Response Without WSDL

Jul 13, 2010

I have to query once an hour to a remote web server to recieve data. However the remote web site does not use web services and state in thier 300+ page document that:

Although SOAP is a recognized Web Services API, the RTO web server does not offer a web services interface. That is, there is no Web Services Description Language (WSDL) file available for usage by participant web services client software.

So my question is how do send a soap request and get a response without the use of a WSDL?

Get Element Data From Soap Web Response?

Jun 1, 2012

I'm trying to get data from a webservice, returning just one result, the number of a given item in stock.

I'm successfully getting a result, but need to strip all the XML code from it to simple return the number, the XML being returned looks like:

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">

[Code]....

With just a couple of tweaks to get the data correctly, most notably changing the content type to application/soap+xml and passing the data as XML.

I am using VB with ASP.NET 2.0.

Wcf - Soap Request Client To Webservice Using .net?

Dec 28, 2011

How do I send/Receive SOAP messages usiung .NET I wanted to invoke a webservice, however not like the way shown in the link above.What I did was, created a service reference with the wsdl url(in a windows application with a button click event)

[URL]

have created a client object

Dim objProxy As MyClient = New MyClient()

I have populated the objrequest and objreqheader using the below methods, (assigning string values and not xml)

objreqheader.id = "abcd"

Finally the below line invokes the service

objresponsehead = objProxy.myoperation(objreqheader, objrequest, objresp)

From reference vb, this is the myoperation public function

Public Function myoperation(ByVal RequestHeader As AFA.RequestHeaderType, ByVal GetTransactionDetailsReq As AFA.GetTransactionDetailsReqType, <System.Runtime.InteropServices.OutAttribute()> ByRef GetTransactionDetailsResp As AFA.GetTransactionDetailsRespType) As AFA.ResponseHeaderType

[code]....

I checked the property of objProxy, it is having basic http binding as the property. Anyone invoked the service like this? From soapui, the response is fine, after i populate the request fields.How can i enable the trace to see what is the request going and where is the problem.

.net - Signature And Timestamp Order On A SOAP Header?

<wsa:MessageID>
