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

This is a bit of unusual problem that I'm experiencing, but recently one of the users of a production application started reporting errors in the system. These were traced to a 503 Service Unavailable error when making a call to a web service used by the application.
Now here's the odd part, only the one user is affected by this issue. Other users of the application have not reported any errors. When the user logged on to a different machine that worked for another user, they still received the error.

login.aspx generates the following error on load, this file worked great for over 2 years, problems with Godaddy forced us to create a new account IIS6 ASP 1.1 which matched the original hosting environment. However now after the migration this file generates this error. Any Ideas why this parsing error is generated?
Parser Error:
Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.
Parser Error Message: Could not load type 'HopeCounselingWeb.login'.

I have a treeview control which is being used to browse various folder on the users system drive. It can also be set up to connect network folders using UNC paths e.g "serverfiles". At the moment I'm getting a list of Directories by using My.Computer.FileSystem.GetDirectories however this obviously fails when the folder is password protected.
Is there a way that I can get Windows to open the credentials dialog as you would see in Windows Explorer and deal with the credentials side so then the user name & password is cached as well?

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?

We're in a strange situation with a legacy winforms VB.NET 1.1 application using ASMX web services. Trying to send a user Token from a WindowsIdentity object as a parameter to a WebMethod. I will be adding a 'HACK: comment. System.Security.Principal.WindowsIdentity.GetCurrent().Token
The token is of type IntPtr, the first problem is the WSDL being generated doesn't support IntPtr with the error of 'unsupported type'I'm aware this is a big WTF question and sounds insecure, so any simple helpful alternatives are welcome but there are a lot of constraints on how we can change this system, including complications with the hosting environment. So I would just like to get our piece of data over to the web service to save a lot of other headaches.

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:

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

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?

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.

Through COM, one can potentially gain absolute control over a target system. For example: using javascript's ActiveXObject object in IE, one can create certain objects which were designed to have direct access or interaction with system properties and files.One would think common sense dictates users disable ActiveX features in IE immediately after installing the browser to ensure their system is protected while surfing the net, or at least paying close attention to which websites they permit. But, I doubt many average PC users know how or why to do this, or just get tired of mirco-managing it over time. I think any PC user or admin my COM class caters to would greatly appreciate not having to deal with that. Thankfully it looks like IE versions come packaged with ActiveX disabled by default nowadays.
I've built a very versatile COM class library in VB. I didn't intend for it to be callable from any website, but that feature is just part of the COM platform. I'd like to prevent the library from being called from IE unless the website is on a white-listed domain to proactively protect the user (and ultimately their entire intranet) from harm from malicious websites. What would be the best method in VB.Net to tell which application called my DLL, to be able to tell if it was called from any command or process originating from IE? And, what domain called my dll? System.Environment.GetCommandLineArgs()(0) gets me the calling application path. With this info, I can compare it to a black/white-list of applications.

I use an XPathNavigator Select to get a node iterator in the code below and get an invalid token error. If I take out the @contract I do not get an error. I then have to use MoveToAttribute, which works, but shouldn't be needed. Why do I get an error when the @ syntax is valid XPath?

I am trying trite code that will copy information from an infopath document to a word document that is being used as a template containing only a header and footer. The only reason for the code is becausthe footer (not optional) is too long to be handled by Infopath (which has a 255 character limit) and word can hold the full footer. Following the guidance on
Public Sub CTRL1_5_Clicked(ByVal sender As Object, ByVal e As ClickedEventArgs)

I checked the code example at [URL].. and found one interesting thing: if we remove Public ReadOnly Property Items() from OrderItemData class, the service shows an error. Even if we don't try to access Items, and only working with Orders.Can somebody explain why this property is needed?
EDIT: To clarify: the property isn't used directly. I removed it from the code, it compiles successfully, but service returns Request error: "The server encountered an error processing the request. See server logs for more details." And there is no exception thrown.
I think that the service for some reason might need IQueryable(Of Item) property. Even if the property returns Nothing, the service starts working again:
Public ReadOnly Property Items() As IQueryable(Of Item) Get Return Nothing End Get End Property

I call upon your combined intellects. I have a web application with a silverlight app that calls a ria service. The ria service is defined inside the web application and everything else is just dandy.
The issue is this.It is my understanding that in order for the silverlight application to talk and know what the ria service is, you need to add a service reference for that service. The service reference defines the ria service and sets up the connection binding. One of the files it adds is the ServiceReference.ClientConfig which has the connection binding in it. During the course of this application's development, this is the way it was set up. And it worked perfectly fine locally and on the dev server.
Unfortunately there were issues when deploying to the clients in-house server. At this point I was onto other projects while my co-worker continued with the deployment. He soon became frustrated with the goofy errors that were occurring and recruited some help. This dev came in and, albeit got it working, but in order to do so he removed the service reference from the silverlight project but left the ServiceReference.ClientConfig which pointed to the location of the service in the web application(but that's it, no definition or explanation as to what the service does and I'm not sure how the silverlight app is supposed to know how to work with it..). This works perfect on my co-workers workstation and he has deployed this version to the clients server fine.
When I open the project it doesn't run at all. And the reason why is that it doesn't know what the service is that i'm using in code. Specifically, it doesn't know where this is (names changed for clarification):
Imports SilverlightApp.ServiceReference.WebApp.Service
I have cleaned the solution, completely deleted and got the latest from source control, built the web app first and made sure the asp.net dev server was running so that the address in the ServiceReference.ClientConfig resolved correctly. But, alas, it still doesn't know what Imports SilverlightApp.ServiceReference.WebApp.Service is.
So, to get it working on my workstation, I added the ServiceReference back but kept the current connection bindings so that it matched the endpoint in the web app web config. and changed the import statement to Imports SilverlightApp.ServiceReference and everything works fine.
