Setting the current principal on a showdialog.

Posted By:      Posted Date: October 26, 2010    Points: 0   Category :Windows Application


I'm having an issue in creating a custom principal on a login form for my application.

I load the application and then throw up a login dalog on the main forms shown event.

i have a custom prinicpal class that i apply to the current thread in the login dialog and that works fine when i call the show method on the login form, however when i display the login form with the showdialog method the setting of the current principal does not persist

I guess this is because the showdialog method is called on a seperate thread?

I did attempt to apply the prinical to the whole application by using AppDomain.CurrentDomain.SetThreadPrincipal(principle) but this failed to set the principal for the whole application?


If anyone could explain to me what is happening that would be good.




please see code below for further information

Creating Sites/Lists/List Items under Current User Context in SharePoint By Using SPUserToken

Usually we do this by performing the action under RunWithElevatedPrivileges method and updating the listitem using SPListItem.SystemUpdate() method (see here). but this approach has its own flaws like (RunWithElevatedPrivileges will run under system account, we cannot use SystemUpdate for SPSite,SPWeb,SPList, since it runs under system we will "CreatedBy" by as SystemAccount).

Users getting logged out because HttpContext.Current is null


We've  been trying to fix this one for a couple years, and I'm just out of ideas, so any help is really appreciated!

We've got a fairly large, complex web application that uses Forms Authentication to authenticate users.  Throughout the application we store and retrieve information about users in the Session object, and in some cases in cookies.  In a couple places we check for the existence of the context, and if it's null we send the user back to the login page to re-establish the session. 

Just a quick run-down of this web app: C#, .NET 3.5, IIS 6, ASP.NET State Service to manage session

As for the session timer, we use our own home-grown timer, which is basically a client-side timer, which is backed up by a check to the SQL database to see when their last activity was.  This seems to work well for us.  It's not perfect, but it allows us to notify the user before the session times out, and allows us to be certain we're not logging a user out before their 60 minutes of inactivity is up.

What's happening is that certain users are being logged out after just a few minutes.  We've eliminated the timer as a cause and believe what's happening is the HttpContext.Current is null, so the user is logged out.  We do not know why the HttpContext.Current is null, and I underst

Registering controls of current assembly object reference NOT set error


Hi There,

I have created a simple ASP.net Web Application (2.0) and have added a web user control.

Now in my page I have added this control but I have registered like this,

<%@ Register Assembly="WebApplication1" Namespace="WebApplication1" TagPrefix="Custom" %>

Which means I want to access all the controls in my current Web Application project

Then I have added my user control like this,

<Custom:MyUserControl ID="MyUserControl1" runat="server" PublicProperty="Hello" />

Every thing is fine but when I execute the project, NO control on my user control gets "instantiated" and thus I receive error "Object Reference Not Set"

Note that My Control has,

1) Public property PublicProperty as String

2) 1 Label control

In Load Event Handler I am setting Text property of Label Control to PublicProperty. Here object reference NOT set error occurs (which means Label control is NOT initialized).

I don't want to register my control using Src, TagPrefix etc. Any ideas?


Setting default localization



I ever thought that I can set a default localization if the users one (which is set in the browser) isn't available.

I've implemented my localresource files for localization. The start.aspx.resx contains all texts and elements for German use and the start.aspx.en.resx for English users. When I switch the language in the browser settings from German to English everything works fine and the english text is displayed. But when I switch to an other language which is not German or English, it takes defaulty the german resource files.

I've set

UICulture="auto:en-US" Culture="auto:en-US"

as well, but it didn't assume the .en resource file automatically. (For example when I enter the website and switch the browser language to French or Italian it should take the english resource files.)

Thanks and regards,

Setting webpage/masterpage background...image?


I want to have the background of my masterpage (the master page for all of my .aspx pages) have a sort of gradient.  I imagine the only way I can do that is with an image.  Or maybe even some other design, but I want to move away from the "solid color" background.

Is the easiest way to do this just to make an image and set that as the background?  What image size should I make it, because some users could possibly have the normal aspect ratio, or maybe a widescreen?  What should I make it like so that it looks good on all computers?

Thanks in advance. :) 

Knowing the event occured in user control in current page




      My web application has user control which uses third party controls called Devexpress controls. The user control is a menu  and is part of the Master page. It is placed there because this needs to be available in all the pages. My user controls raises a even on item clicked. Now, My question is that Is there any way to know that the event has occurred in page_load of the current page in which I am in?

setting scroll position for a ListBox


I have a ListBox control showing 10 rows.  I have 30 rows total in the listbox.  How do I programmatically adjust the scroll to show the last ten rows?

Some sources have suggested that I set the SelectedItem.  But I am already making selections (myListBox.Items[28].Selected = true, myListBox.Items[29].Selected = true, etc); the listbox scroll is positioned on Item[0] not the first selected item.  I have also tried setting myListBox.SelectedItem in addition to the multiple selection just mentioned but that does not have any affect either.

JSON Deserialize into Entity Framework Object and setting the DataMemberAttribute "Name="




I'm in the process of deserializing a JSON object into an Entity Framework object.  The property names in the JSON do not match up totally with the property names in the Entity Framework Objects. What I'd like to do is set "Name=" on the  "DataContractAttribute" for the table and the "DataMemberAttribute" for the properties in the Designer.cs file.  I tried setting these in the Designer.cs file manually just to see if it would work - which it did (using JSON.Net) but of course when I went into the .edmx designer I lost all my changes.  Is there a way to do this?


Thanks in advance

Setting accessibility mode for multiple web applications


We have a SharePoint farm consisting of 5 web applications. These are tied together through branding and a custom sitemapprovider which present the farm as a single environment to end users. Our visually disabled users however have to enable the accessibility mode for each web application. Which is a nuisance, ideally they would only have to enable once for the complete farm. Does anybody have a solution for this problem.
