how to make sure the user is logged in one time..

Posted By:      Posted Date: December 04, 2010    Points: 0   Category :WCF
 

Hello all,

using Message security with username authentication, is there a way to make sure that the user is logged on once? not from multiple places? can i manage the session and see if the user is trying to login with the same username and password from some where else at the same time he is logged from one pc...?

 

regards

How to make "UserId" equal to the "logged-in user" in vb code behind

  


I need to insert a declaration in the codebehind function below that will make the variable "UserId" equal to the "logged-in user". In what way do I need to change the code below (elsewhere in the project, I successfully make reference to basically the same code and make the UserId equal to logged-in user by using this handler expression inside an image control: ImageUrl ='<%# Eval("UserId","Image.aspx?UserId={0}")%>'...But in the case below, the function is not fired by this expression, but rather by CustomValidator). Thanks very much.

WCF - First call to Callback instance from Server takes considerable time to make it to the client.

  
Hello. There's a performance problem we are facing that we are unable to fix using DuplexChannels. The first call made by the client to the server reaches the server instantly. The first call made by the server to the first client using a Callback proxy will take several seconds to reach the client. All subsequent calls to the client (as well as other clients) will reach and execute instantly. The client connects to the Server using a proxy to IServiceProvision, supplies an instance to an implementation of IClientCallback and calls IServiceProvision.Start(). The server instantly processes the call and makes an asynchronous call to IClientCallback.DoWork(), which takes several seconds to enter the client's DoWork() implementation. The remainder of the execution then runs smoothly. Also, the server will experience such a slowdown only for the very first call of the first client that connects to it. Is it normal for the Callback interface to take so much time to warmup, only on the first call to the first client? Below is the full source code. Thanks for any information you may provide. Cheers Mike Shared Class Library using System.ServiceModel; namespace Test { [ServiceContract(Namespace = "http://test/IService", CallbackContract = typeof(IClientCallback))] public interface IServiceProvision { [OperationContract] void Start(); [OperationContract] void

WCF Service stops after throwing a unhandled exception :no user is logged on.

  
Hi All,       I have written a WCF service which is hosted as a Managed windows service. I consume this service in a web application. The service is built using a httpBasicBinding and security Mode ="none". I'm now getting the following exception, after which the service stops  "An unhandled exception ('System.ComponentModel.Win32Exception') occurred in CMMonitorService.exe [1812]. Just-In-Time debugging this exception failed with the following error: Debugger could not be started because no user is logged on." I had tried changing the security mode to Transport/Message. with windows credential then I get a access to the path denied error. Can anyone provide hint on what am I missing and what would be the appropriate security mode and client credential to use along with basichttpBinding?

FBA users (ldap provider) don't have any user profile info when logged in.... what am I doing wrong

  
Sharepoint 2010, Claims authentication, FBA using ldap membership provider and role provider against Active Directory.  User profiles all imported just fine -- used the LDAP FBA provider hitting Active Directory to do so too.  whenever an FBA user logs in, it doesn't seem like sharepoint is picking up any user attributes.  targeted audiences don't work and MY SETTINGS is blank other than account and name.  If the same user logs in but through Active Directory, everything works just fine... targeted audiences, etc. Am I doing something wrong or can I not use the LDAP provider to authenticate to AD and also use the user profiles from Sharepoint?  GRRRRR.  All this to get around the Windows Authentication popup so I can customize a better looking logon experience.  Help?

Mulitple time and user stamped comments for each custom list row?

  
Does anything int he UI allow for this type of column to be added to a custom list? or would it have to be a seperate list? And on the subject of connecting two list to each other. Ideally, we would connect two lists by the list ID, having one list look up to another. But then the issue is having to know the ID.Anything in the UI allow a user to select one column, but save the ID for that as part of the lookup? Thanks.

how to keep from deleting logged-in user

  
I have a CreateUserWizard that always deletes me as a user from the database whenever I test it. My default test browser is Firefox, which automatically fills in my user name and password. Consequently, whenever I try to break the operation on that page, I forget about my user name being written there and my Membership.DeleteUser kicks in and kicks me out of the DB, with this code:Page.Validate() If Not Page.IsValid Then Try Membership.DeleteUser(Profile.UserName) Catch ex As Exception Finally e.Cancel = True End Try End If I believe what I need to do is precede the Membership.DeleteUser statement with something like "If User is not logged in then" but I can't find how to write the syntax for this. Any opinions on how to write this, or if some other method would be better?
