C# - WCF WSHttpBinding SOAP Security Negotiation Failed?
Feb 1, 2012
I've got a fairly simple WCF self-hosted service using the WSHttpBinding that just refuses to work. If service and client runs on the same machine there's no problem, but as soon as I move the service to the window-server 2008 the client fails the communication attempts with
EXCEPTION
[System.ServiceModel.Security.SecurityNegotiationException] {"SOAP security negotiation with 'http://hvw-svr-01/SIT' for target 'http://hvw-svr-01/SIT' failed. See inner exception for more details."}

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.

I am trying to create a VB.NET app that will capture failed windows logins without having to read from the security log. I know I can do ManagementEventWatcher and watch forWin32_LogonSession. But this only gives you successful logins. Is there anyway to do this? I figure I am just missing the correct class that will do this.

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.

I've been trying to create a simple service to allow messages to be logged onto a remote server via WCF, which all worked fine until I published the service to the live environment, which uses HTTPS.
After some searching, I found that I needed to change my ServiceConfig to account for the different protocol. I used a combination of these two articles:
How to configure WCF services to work through HTTPS without HTTP binding? WCF Bindings needed for HTTPS
Having made the recommended changes to my config, I seem to be in a state where I can add the live service as a WCF reference in VS2010, but when I use IE to browse to the service or the mex address, I'm consistently receiving an 'HTTP 400 Bad Request' error.
In terms of using the service I can seem to run it successfully but the mex just doesn't want to work through IE.
The Service itself is being hosted on Windows Server 2003 R2 Standard Edition SP2 Running IIS 6.0 with no load balancing.
I'm really at a loss at this point, I've spent 3-4 days messing around with this but I can't seem to make any progress.
See below the Server service config in question:
<system.serviceModel>
<services>
<service name="mycorp.Callback.SecPayService"

I'm trying to send a file via FTPS. I'm a mid-level VB programmer but I've not dealt with FTPS or SSL before.
Dim thereConnectionString As String = "ftp://" & thereHost & "/%2F/" & therePath & "/" & hereFileName
Try
Dim clsRequest As System.Net.FtpWebRequest = DirectCast(System.Net.WebRequest.Create(thereConnectionString), System.Net.FtpWebRequest)

The GetRequestStream is throwing the exception:The remote server returned an error: 234 SSL enabled start the negotiation.

I'm using Visual Basic Express 2010 and SQL Express 2008 in Windows XP. At first I couldn't add a datasource (the .mdf file for the database) because of a "Operating system error 32" which I seemed to have resolved by giving myself full permissions for .mdf file (by right clicking on the file and going into properties and then Security) and restarting the SQL SERVER (SQLEXPRESS) service. The dataset for the database is in my solution explorer but when I right click on a table adapter to add a query and attempt to open up the query builder, I get the error in the title above.

I created a typed dataset a day or so ago, then I added a whole bunch of tableadapter/tables with some relationships etc... suddenly out of nowhere it decides my dataset "is not defined". everywhere in my code where i use this dataset now has an error. I tried not to pull out my hair and do a Clean then Rebuild solution... out of nowhere it just refuses to generate code. Object reference not set to an instance of an Object. It would be nice if it was my object so i could find it but it's not.
Curiously I also lost the little database icon on the dataset in the solution explorer.I can still open it in the designer and preview my queries etc... it just wont make the code. it's driving me insane. anyone got a solution?

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?

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

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?

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)

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?

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/">

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.

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.

Take the tripservice wsdl from this link In this wsdl, I replaced the from element with the below(added nillable as true and added min length and max length restriction).
[Code]...
The element from xsi:nil="true" is generated, even though i am not touching the element in my vb.net code to generate the request. The element is optional as per the wsdl(min occurs = 0). How can i send a request without the from element name, even passed in the request?

I've been developing a vb.net client that connects to a Webservice using SOAP. This Webservice needs the SOAP message to be signed and have a timestamp.To this point all is possible, using WSE 2.0 SP3 I've able to sign the message and include the Security tag into the SOAP Header and the timestamp tag is included too, as you can see in this sample:
This is what I send
<soap:Header>
<wsa:Action>http://www.openuri.org/procesa</wsa:Action>
<wsa:MessageID>
uuid:8462973d-f108-4b27-999f-730663978d5b</wsa:MessageID>

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?

We have a VB6 application that consumes Java webservices with soap.That works fine on XP and Win7. The login to the webservice times out.Under xp the client try to reconnect 2 times (is one call to the webservices) and then ask for new login data from user. With win7 that dont be OK.If the login is timed out, the client try to reconnect 9 times with one call. The code is the same. I trace this with wireshark.
