.net - Send HTTP Auth Credentials With A WCF Service Reference

Sep 4, 2009

I'm attempting to consume a HTTP Basic Auth Secured PHP WebService using VB.NET. I've so far managed to get 100% perfect integration by adding it as a Web Reference and doing the following:

Dim Credentials = New System.Net.NetworkCredential("username", "password")
Dim CredentialCache = New System.Net.CredentialCache()
CredentialCache.Add(New Uri(MyWebService.Url), "Basic", Credentials)
MyWebService.Credentials = CredentialCache
MyWebService.PreAuthenticate = True

I can also successfully add the webservice as a 'Service Reference' and this also works fine, as long as i turn off all HTTP authentication on the SOAP server.

My problem is that I can't find any documented means of sending basic HTTP Auth Credentials when using Service References as opposed to 'Web References'

Am I right in my understanding that 'Web References' are a legacy method of Web Service consumption?

Asp.net - Send HTTP Authentication Credentials To A Non .NET WebService?

Sep 3, 2009

i'm doing everything by the book, but the .NET client is simply not sending an authentication header when making requests to my (PHP) SOAP Web Service. I have verified this by logging the raw post data at the PHP end of things and .NET never sends any auth headers.This is the code I am running before making calls on my ExampleWebService Web Service:

ExampleWebService.PreAuthenticate = true;
NetworkCredential myCred = new NetworkCredential("myusername","mypassword");
CredentialCache myCache = new CredentialCache();

[code]....

As I understand it, PreAuthenticate should force the sending of my HTTP Basic Auth Credentials on every request regardless of challenge. Does this only work with IIS hosted services?

Creating A File Using Impersonated Credentials Via A Service?

Nov 4, 2010

I've spent alot of time digging thru the forums to research this problem, and to get the right code. I'm wondering now if this is a system configuration problem, or something else with my code.

Firstly, i'll tell you that i've already put the service account on my machine local security policy that says 'allow to act with/as operating system'.

Running this code from an application, it works just fine:

Manage Remote Service Using Alternate Credentials?

Jul 19, 2010

I have to admit that I was sceptical it would work... but below is the code. I had to make a minor change to the code you suggested. Whenever I tried IPC$ it would return a 53 result code, even though I'm sure the share exists. So at the suggestion of another website I removed the share and just the computer name and this worked.

Imports System.Runtime.InteropServices
Imports System.Net
Imports System.IO

VS 2010 Programmatically Start/Stop Service Using Different Credentials?

Jan 17, 2012

I was able to programmatically launch a service on my development server from a workstation using the ServiceController class with no problems.

When I try to programmatically launch the service on my production server from my workstation, I get an access error which means I do not have rights to run the service with my logged in ID on the workstation.

My question is, is there a way to launch the service using different credentials? I do not see anywhere to input these credentials in the ServiceController class.

Calling A Web Service That Requires Credentials: Error: A Security Token Is Required?

Dec 20, 2011

When I try to call a [Java] web service from .NET, I am getting what appears to be a security credentials issue. CWWSS5509E: A security token whose type is [http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#UsernameToken] is required.Is it even picking up the credentials that I am trying to pass? At this point, I just want to make contact with the web service and get access. In my example, ServiceReference1 is a generated Web proxy class.

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim myLocateProfileBySourceSystemId As New ServiceReference1.locateProfileBySourceSystemId

VS 2008 - SMTP.Credentials Required To Send An Email Or Not?

Sep 29, 2009

I'm making an application in which clients can send an SMTP email. In this application a client must select their internet provider, this possibilty already works. While testing it I tried to deactivate the SMTP.Credentials in which a username and password must be entered. Deactivating/romoving this line has no effect on sending the emails.?. I tested it on my office and at home, with 2 different providers. All mails were send.

My question: Is SMTP.Credentials required to send an email or not? What effects can deleting this line have?

Service Reference Stops Working When Make Changes To WCF Service?

May 26, 2011

I'm using Visual Studio 2010 and .NET3.5. I've created a WCF service application. I'm including two DLLs that contain the types I'm returning. The first method I wrote works both in WCF Test Client and also in a console application I created to test. When I move on to the next method that returns a generic list of a type. It works great in WCF Test Client, but when I update the service reference it acts as if the service is unavailable. All my objects say can't find reference, and I can no longer see it in the object browser. It's like it just disappears. I can still see it in the Service Reference folder. If I go back to the WCF app and comment out the contract and implementation of that one method it work again. I created a local class very similar to the class I'm using from the dll, and the it works. Is there something I'm missing here? Can someone point me in the right direction?

VS 2008 : Expose HTTP Access To A Background Service?

Dec 16, 2011

I'm creating an executable that will run as a background service.I want to communicate with this executable with a browser - similar to how you talk to sophisticated copiers in a big office.and was told to build an HTTP interface in that app.All the examples of httprequest and httpresponse I can find are about talking to web sites - or public services.How would I go about having my app "fire an event" when an async POST is made from a browser page? How do I wait on a port in the app?

Reference Current Http Context When Using HttpListener?

Aug 6, 2011

When using ASP we can reference HttpContext.Current from anywhere in the code to get at the current http context.

I want to do something similar using HttpListener, so that I can access GET/POST data etc from anywhere in my code. Can I reference some global object for this, or do I need to explicitly pass the current HttpListenerContext object all through my code?

Send A HTTP Request To A Servers Interface?

Jan 12, 2012

I'm trying to send a HTTP request to a servers interface.But I'm really confused about how to specify the parameters I want to send to the servers interface method. What I've done so far.My server interface only accepts POST requests, that's why I'm using POST and asked if something is wrong with the way I use the parameters.

Dim parameters As String = "?text=test&type=person"
Dim buffer As Byte() = Encoding.UTF8.GetBytes(parameters)
Dim WebReq As HttpWebRequest = CType(WebRequest.Create(NameRecPage), HttpWebRequest)
'NameRecPage is the url

Send POST Body With HTTP Request?

May 3, 2010

I have used the WinHttp.WinHttpRequest object in VB6 to make HTTP POST requests many times. It works great: .Open the URL, then .SetRequestHeader (however many are needed) and then .Send the body. The .Send method makes the actual connection and sends everything to the server at once.How to I emulate this behavior in .NET? The examples I've tried with System.Net.HttpWebRequest open a stream with .GetRequestStream() and then write the body to the stream. Unfortunately, the server is responding immediately to the .GetRequestStream method and therefore never sees the POST body.I am obviously trying to connect up some legacy stuff here, but am having a hard time Googling the problem or finding another approach in .NET.

HTTP 404 Not Found Error On Web Service Call, Only With Large Amount Of Data

Sep 2, 2011

I have a vb.net Windows application that calls a vb.net Web Service function. Both the vb.net application and Web Service have been in use for over 5 years and have worked well. The Windows App builds a text file consisting of a number of inserts into an Oracle table, followed by a call to an Oracle package. The Web Service call uploads the text file to the Web Server, loops through the statements in the text files and executes them. It then does a Select statement to put the resultant data in a string which is passed back to the calling program. We have both people on our local area network as well as external users where the call to the Web Server is over the internet.

The data string returned is the pricing for each of the lines inserted in the text file, separated by asterisks. Normal use of this call has anywhere from 1 to a few dozen lines, and the program works fine for this for both internal and external users.

Our problem right now is one external person is attempting to price a job with 491 individual line items. At first it would not price, whether the job was priced from a computer at the customers site or one of our internal people on the LAN. The problem turned out to be the timeout value was not long enough (it was set at 2 minutes, this job takes 5 minutes) so changing both the Timeout value in the Web Service call as well the httpRuntime executionTimeout value in the web.config file on the web server addressed the problem, but only for our internal users on the LAN. Our external customer wants to be able to price jobs of this size going forward, and I am at a loss as to why it errors on internet connected machines but not locally connected machines. Our customer is in New York, We are in Wisconsin, and I am able to recreate the error condition from my home computer.

The other thing is, if I create a VPN connection to our server from my computer at home, this job will price (again, it takes about 5 minutes) but if I disconnect the VPN connection, it gets an error after approximately 3 minutes, http 404: Not Found.The customer can otherwise price all of his other jobs with no problems, it's only this one, very large job that gets the error.

.net - Service Reference Client Bug?

Aug 16, 2011

i have a WPF application that uses a service reference to a web service.Now i have a GUI component that tracks the progress of this...But i seem to have some sort of bug here, it only occurs on some machines and not often..I start a call with MethodNameAsync and display the progress bar until the matching Completed event occurs.

some times i call 3 different async methods in a row but only the two of them get their Completed event raised so the GUI will be locked and the application has to be restarted.After being totally frustrated a few weeks i found the event AppDomain.CurrentDomain.FirstChanceException, so i hooked up to it and started logging all FirstChanceExceptions..

[Code]...

Fix this temporary by not using async methods and instead using a thread that will call them one by one.. now this is not a elegant solution, i should be able to use the async methods...

WCF Without Adding Service Reference In Vb?

Mar 28, 2012

I'm just a starter in silverlight and WCF. I came across a very good article here by Miguel A. Castro which teaches to add the WCF manually. I have the contract service setup and the only thing I left is to get the data back from the service in the silveright. I have a hard time translate the code to vb.net.

BasicHttpBinding basicHttpBinding = new BasicHttpBinding();
EndpointAddress endpointAddress = new EndpointAddress("/Person.svc");
IPersonService personService = new ChannelFactory<IPersonService>(basicHttpBinding, endpointAddress).CreateChannel();

[code]....

How should that be written in vb.net?
