Access the user session from a web method

Posted By:      Posted Date: October 29, 2010    Points: 0   Category :ASP.Net
 

I want to access the user session from a web method. But when I check for the session object, its nothing! How can I access the current user's session from the webmethod?

My code:

<System.Web.Script.Services.ScriptService()> _
<WebService(Namespace:="http://tempuri.org/")> _
<WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)> _
<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _
 Public Class DalService
    Inherits System.Web.Services.WebService

  <WebMethod()> _
    Public Function AddFavourite(ByVal locationId As Integer) As Integer
        Dim result As Integer = 0
        If Session IsNot Nothing Then
            'DO SOMETHING
        Else
            ReportError("SESSION IS NOTHING!!!!!!!??????", "")
        End If

        Return result
    End Function

End Class

Access denied when user clicks refresh BDC column button

  
Access denied occurs with any non Site Collection Administrator regardless of rights.  It only occurs in this site collections, others they are able to refresh.  In this particular collection they can add a BDC column to a list, edit an item and place/resolve a value in the bdc col; but when they refresh they are given an acess denied.  Any thoughts on what they need read access to?  This goes away if I give site admin privs (dont want to do that) or give them read only access on the web application (dont want to do that either).

Task assignment to user without read access in 2007 results in no email to assignee, no warning to a

  
It appears (from observation and searching) that SP 2007 will not send a task assignment email when the assignee does not have read access for the assigned task and there is no warning when assigning a task to someone who will be unable to read it. I have not been able to find any mentions of attempting to address this quirk by either an item event listener or a workflow that would either prevent the assignment or task the originating user to fix the issue by either changing the assignment or having them added to the appropriate group.  I could see one done badly causing a cascade of tasks. The approaches that I've thought about are: Attempt to block assignment by hooking ItemAdding and ItemUpdating on the task content type.  In ItemUpdating, you could use SPListItem.DoesUserHavePermissions since the SPListItem should be there, but you'd may have check the list since I don't think SPListItem is available at that time.  I could see this causing problems when the assignment is via workflow or something that doesn't like other code interfering with its task creation. Hooking ItemAdded and ItemUpdated to assign a new task to the assigning user to either change the assignment or have the assignee added to the users with access to the site. Define a workflow which could be enabled for a list that would check if any new or modified task is assigned to users with

Problem with access to a user in AD group

  
Hi all, We are managing our security in Sharepoint (WSS 3.0) with AD groups instead of Sharepoint groups. This worked fine until now. For an unknown reason, one single user from an AD group cannot access a page (while other users from the same group can). The group is also a distribution list in AD (so it's a security group and distribution list for emails). It includes several other distribution lists such as: L-All-Corporate-Employees    L-Administration          User 1          User 2           ...     L-Accounting         User 1         ... ...   So far I never had any issue with that kind of approach,  but yesterday we published a new web part page and wanted only the corporate employees to get access to it, so I broke rights inheritance on the page and added the L-All-Corporate-Employees group with View rights. As I already said, I tested with one user from the group (let's say from the L-Administration sub-group) and it works, now I receive an email from another user (let's say from the L-Accounting sub-group) which tells me he doesn't have access... But they're all part of the L-All-Corporate-Employees group, so they should all

Accessing Session State in a User Control

  
We have a web site that implements a custom SiteMapProvider using a User Control added in the master page. I need to be able to limit the sitemap nodes added depending on the logged in user, that is, certain users should not see certain sitemap nodes. Currently, the login processing code determines if users are in the certain category or role and then sets a value in session state, for example, Session["UserInRoleXXX"] = "Yes"; I tried changing the code in the user control to check the session state, but I got the following error: NullReferenceException ... Object reference not set to an instance of an object." Can session state be accessed in a user control? If so, how? If not, any suggested solutions? Thanks in advance for any help.

Creating and sharing new sharepoint site to internet, limiting user access

  
I am a new hire into an existing business as I.T. I know the networking, I know the computers. The owner now wants me to learn Sharepoint among some other things. They currently use WSS 3.0. I have been reading up on this for the last month. I think I am ready to extend the current site to make it an Internet site so the employees can login. Some other things we would like to do I have read up on and it looks like they can be done, things such as inventory tracking in collaboration with QuickBooks and creating a website / portal for clients to have a unique login on and can see the status of their jobs in custom SharePoint lists. As far as I can tell the clients need an AD account. However, apart from that I am not sure what to do. A little background.  The company has multiple clients, and we ship things out daily to those clients.  We use Sharepoint to track the status of the jobs as they progress through the stages ultimately going to delivery. There is one common page that lists all the jobs by all clients that is updated constantly. We would like to allow multiple (different) clients/logins and have a page customized for each client.  For example, you are a client and go to www.companyname.com/sharepointsite.html.  From there you would get to a portal page with a login. Once logged in you will be presented with the Shar

Object Cache set with Portal Super User accounts. Access denied to site.

  
I have the same issue on multiple farms. In this example i'll outline this problem for a three tier farm. SharePoint web server SharePoint Application server (hosts central admin) Sql server After installation and configuration i have created two web applications (claims based auth with NTLM). https://portal.contoso.com https://mysite.contoso.com The client connects on the URLs to the web server (1st tier). All is working correctly and they can access the portal and their mysite. The log file keeps reporting that i need to configure the user accounts for the Object Chache. So, i looked up the required steps and executed these conform mcrosoft guidelines (http://technet.microsoft.com/en-us/library/ff758656.aspx) All the steps run seccesfully. But when i connect to the URL i now get an access denied (even with the administrator who is site collection administrator) In the log file i get the following to lines when i connect to the site. Unknown SPRequest error occurred. More information: 0x80070002 Unknown SPRequest error occurred. More information: 0x80070005 I have exact the same issue on two other farms. Marc

Anonymous access - User prompted for login after click in web part area

  
I have a MOSS2010 site, internet-facing using anonymous access. I've found workarounds to many of the anonymous access issues I've come across, but I don't know how to fix this one. Any ideas or assistance would be appreciated. A user visits one of my pages with a OOB webpart. If they click within the area for that web part, essentially selecting the web part, it prompts for a login. I don't want my users getting prompted for a login, but I don't know why they're being prompted in the first place. According to the logs, it looks like it is trying to access _layouts/wpribbon.aspx. They aren't clicking on the items (titles aren't clickable), it's the area within the web part box. Can I make that area non-clickable?? Go to: www.carlile.biz/careers/pages/current-openings.aspx Click on the area around the Locations or the Current Openings listed. Either will prompt for a login. Even with a valid login, the view does not change and no further options are presented.
