.net - WCF Client Returns "nothing" As A Response To A Third Party Webservice

Jul 8, 2010

I have a 3rd party webservice (happens to be a peoplesoft EIP service) that I'm trying to call from .net. I've tried using a service reference and the old web reference to call this service and every time I call it I get a response of "nothing" back from the service.

I've ran the service call through SoapUI and it works fine. I've captured the network traffic using Fiddler and notice that when i call the service from SoapUi or from .Net I get the same resulting xml back from the call. So that means the call is working. I've turned on tracing and logging within WCF and I'm not seeing any errors. Nor is it throwing an exception.

So my theory is that .net is having a hard time translating the xml from the service back into a .net object.

Here is a snippet of my code:

Dim psclient As New psService.LSS_WEBORDER_PortTypeClient
Dim psreq As New psService.LSS_WEBORDER_REQ_MSG_TypeShape
psreq = New psService.LSS_WEBORDER_REQ_MSG_TypeShape

Send JSON As Response From A WebService In .NET?

Jun 20, 2012

I'm building a Web Service in VB.NET and I want to answer using JSON.
Currently my answers looks like this

{"myVar1" : "From moscow", "myVar2" : "With love"}

I would like to be able to use " (and CarriageReturn), and have the reponse like this :

{"myVar1" : "From moscow", "myVar2" : "With love"}

How can I avoid this transcoding of the " in " ?

Here is my interface definition :

<OperationContract()>
<WebGet(UriTemplate:="/TemplateGet?ID={id}",

.net - Response.Redirect Does Nothing (ASP.NET) And EventValidation Returns Error If Enabled?

Mar 7, 2011

I have a page in which one chooses from a selection of dynamically generated buttons. The ASPX code is as follows:

<div>
<asp:Repeater ID="rptrHalls" runat="server" OnItemCommand="Choose_Hall">
<ItemTemplate>
<asp:Button ID="btnChooseHall" runat="server"

[code]....

When I first tried running the code I received an error message of "Invalid postback/callback argument". I set the ASPX page to have a enableEventValidation="false" property and tried running it again. It generates the page fine but when I click on a dynamically generated button it acts as if it is loading something and then just brings me back to select_hall.aspx (the page all this code is one), when (as you can see above) it should take me to select_room.aspx.

Consume Gsoap Webservice From .NET Client

Jun 22, 2010

From a .NET application, how do I consume a Web Service developed using gSoap c/C++ library? I can create a C/C++ client using gSoap library to consume the web service. But I need to consume it from within a .NET (C#) application. I tried Adding a Web Reference but that doesn't seem to work. Would I need to work with raw Soap Packets?

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.

WebService - Not All Properties Showing On Client

Jul 16, 2009

I have a vb.net baseclass in a dll in my c# project. I created a derived class in c#. I fill the C# class with all its properties, including the base properties from the vb class. Now I send them through a webservice (c# ) to a jQuery client. But on the client I only see the vb properties?

public class FilmItem : ContentItem // ContentItem is from VB DLL {
public string Zender { get; set; }
public string Jaar { get; set; }
[WebMethod]
public IEnumerable GetContentItems(VBLib.GridRequest gridRequest) {
ContentCache contentCache = new ContentCache();
return contentCache.GetFilms(gridRequest); // gives back a List<FilmItem>
}

Just found out that if I remove the vb.net class, all the properties are showing fine from the C# class. Also found out that the vb.net is declared like this:
Public Class ContentItem
Inherits System.Collections.Generic.Dictionary(Of String, Object)
Implements IContentItem
Could it be the dictionary or the interface? (Which sums up the properties I was seeing).

.Net Desktop Client Cant Connect To Offsite Webservice?

Aug 6, 2010

I have written a vb.net app that runs in multiple hospital networks. THe vb client periodically contacts a off-site webservice for datatransfers.The issue I am getting at a particular hospital is that the client PC's are not on the hospital's domain. So they are sort of off the radar. They do use the hospital network for internet access. When the user opens a web browser they are asked for domain

userid and password. If not are provided then they cannot proceed. What do I need to do with my vb.net code to make the webserver calls prompt for and use the proper domain user id and password?

.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)

Getting A Response With A .NET Client From A Java Web Service?

May 26, 2011

Here's the situation. I'm a Java developer. Another developer in our company wrote a web service for our clients. They wrote the service in Java. They also wrote a demo for creating a client to consume the web service in Java and it works just fine. I've been tasked with creating a web services client in VB.NET to do the same thing. It hasn't been going smoothly. The problem is that the web service requires that you send the username and password in the SOAP header and I can't figure out how to do that in Vb.NET. I looked at the following pages:

Web Services - .net SOAP Webservice Client "Unmarshalling Error: Unexpected Element?

Jul 28, 2011

I am building a client in VB.net for calling webservices methods from a partner organisation.[URL]../system.web.services.protocols.soaphttpclientprotocol%28v=VS.71%29.aspx because I can't get it to work using the Web References feature of Visual Studio 2010 (when I try to do that it turns the methods from the WSDL into classes).I have created a proxy class and can instantiate an object of that class no problem.

However, when I try to call a method which requires arguments I get this error:

Unmarshalling Error: unexpected element (uri:"http://api.service.apimember.emailvision.com/", local:"key"). Expected elements are <{}key>,<{}login>,<{}pwd> Does anyone have any idea why this might be? (If it's helpful I can post my code and the location of the WSDL.) (P.S. I can get the whole thing to work fine in PHP using ZF Soap classes, but for various reasons I need to get it to work using .Net)

Edit to add: I have used Wireshark to examine the outgoing and incoming SOAP message to compare them with the messages being sent via SoapUI, where it all works fine.What this has shown is that my VB client is sending a message where the namespace of the web service I am trying to access is declared as an attribute of the method, and not in the soap:envelope attributes.

Nov 21, 2009

I am using a client.openRead to send request and passing line through finalurl.

Dim data As Stream = client.OpenRead(finalurl)

Now my server blocks ports and i am getting error on this line now is there any other solution to client.OpenRead and what ever i am sending throught this is code is going on other company's server so i can't tell then to change their way so is there any other solution to this?

Dim data As Stream = client.OpenRead(finalurl)

And in final url i have other sites url and some querystring data

For example

dim finalurl as string= [url]

I already use WebHttpRequest but it not works still server not allow it.But i try it with response.redirect and it works but not suiteable to my conditions.i want control on my site so i was using Dim data As Stream = client.OpenRead(finalurl) but now server block some ports due to some reasons

O_O How can this be returned? Is this normal? Is this possible? How can the request have originated from localhost (127.0.0.1) and at the same time from a remote IP-address? Was the server hacked? Is this a glitch? This was posted some time ago on [URL]: [URL] but no one answered, so I am asking it here again.

SMTP Email Client Fails On Local Machine Needs To Run On Client

I have an application that takes a series of reports and sends them as attachments in an email to a specified group of email accounts.

When I run the Java version of this using apache commons and the same setting, the email is sent. However, when I run the VB.NET version of the code, it fails on my local machine and on the client machine.

I have a VB.NET web application running on a server that uses similar code. I tried that code locally and it fails. Yet, the web application is working perfectly.

Why is it that the Java application can send the email, but the .NET application cannot?[code]....

Null Check Always Returns Null, If Removed Returns Object Reference Not Set To An Instance Of An Object

Jun 24, 2010

I have some code which gets child items for a menu via the GetChildren function which takes a list of menuData: Dim builtMenu As New List(Of MenuData)(_rawData.FindAll(Function(item) item.GroupingID = 0))

For Each menuData As MenuData In builtMenu
If menuData.Children IsNot Nothing Then
menuData.Children.AddRange(GetChildren(menuData))
End If
Next

If I check if menudata.children isnot nothing, it always is nothing because the GetChildren function is yet to run (providing the child items, which do exist). If I remove this check and just have this code:

Dim builtMenu As New List(Of MenuData)(_rawData.FindAll(Function(item) item.GroupingID = 0))

For Each menuData As MenuData In builtMenu
menuData.Children.AddRange(GetChildren(menuData))
Next

Then I am presented with a Object reference not set to an instance of an object error on menuData.Children.AddRange(GetChildren(menuData))
