Logging From Framework Internals (Logging.On) - How To Turn On Logging

Jul 6, 2010

I'm debugging some unexpected behavior and while tracing in to the .NET framework I see a bunch of stuff like this:

if (Logging.On) {
Logging.PrintInfo(Logging.Web, this, SR.GetString(SR.net_log_n_certs_after_filtering, filteredCerts.Count));
...
}

But (as expected by default) the execution steps right over these. Is there some way to turn on the logging? Or is that just something that the framework developers can do while making special builds of the framework?

Security :: Membership Providers And Database Access

May 20, 2010

I am new to using the membership provider. I have been working in a small shop that has very focused programming and we are starting to venture out as our needs have grown. My question is the following:

Once I have created the asp schema and I set up users. How do I perform database access using those user accounts? I know how to perform access using a database account (schema), but do not understand how to use a user that only exists in a user table to access data tables.

Do I use an anonymous account and control access on the front end?

How to I track audit fields?

Security :: Logging In Without The Login Control?

Jul 13, 2010

I have created a login page which uses the Login control. If the user is not already registered they a redirected to another page to register. My client wants them to be logged in from when they register, and taken to the main page of the application.

How do I log a user in manually, without using the Login control? Am using forms authentication, and have the dbo.aspnet table and stored procedures already created.

Security :: After Logging In How To Retrieve The User Name

Apr 26, 2010

FormsAuthentication.RedirectFromLoginPage(txtUser.Text, false); After doing this, the user is logged in with the txtUser.text

Performance - What Logging Listener Should Be Used In Production ( Logging Application Block)

Sep 10, 2010

I'm using MS Enterprise Logging Application Block in an ASP.NET website.

For production launch, I will set up a log listener in one of these locations:

Sql Server database
Windows event log
Text files

Which has the least impact on performance?

NB - I can't switch to Log4Net or ELMAH at this point, so don't suggest that in your response.

Security :: IE8 Session, Logging Out From One Tab Causes Both Tabs To Logout, But Can't Log Back In?

Nov 10, 2010

I have a website built in ASP.net 3.5, using WinForms and AjaxToolKit. I have encountered a lost/corrupt session issue while using Internet Explorer 8.

Scenerio:

1 IE8 Browser Open, 1 Tab
--------------------------------------

1. Login, Redirect to Landing, Logout - WORKS AS EXPECTED
2. Login, redirect to Landing, Close Window, Open Window, Logged-in already - WORKS AS EXPECTED (remember me enabled by default in code)

1 IE8 Browser, 2 Tabs
--------------------------------------
1. Login, Redirect to Landing, Open new tab, paste Landing page URL, Landing renders. - WORKS AS EXPECTED
- Logout from Tab 2, Tab 1 logs out after AJAX update. - WORKS AS EXPECTED
- Login from Tab 1, Redirects to Landing, then Redirects back to Login page - ISSUE

[code]...

2. Close Window,Login,Redirect to Landing - WORKS AS EXPECTED

2 IE8 Browser, 1 Tab
--------------------------------------
1. Open 2 IE windows
2. In Window 1, Login, Redirect to Landing, then Redirects back to Login. - ISSUE
- Window 2 Paste Landing page URL, Landing page renders - ISSUE, STRANGLY NOW WORKS

[code]...

This issue seems to only happen when I have multiple tabs open,or multiple rwssers open.Firefox and Chrome does not reproduce this issue and works as expected.How do I make sure the Cookie/Session is being handle correctly in IE8?

Here is my Login Auth:

[Code]...

Web.Config

Server 2008r2
Seesion State:

Security :: Configuring Web.config For A Folder That Requires Logging In?

Jun 13, 2010

I have a problem configuring web.config file. In root directory I have a web site that doesn't require logging in to be viewed (public section of the web site) and I also have a folder ("Administration") that needs logging in to get access to it. Login.aspx is located in folder "Administration".

The question is how to properly set up the web.config to connect Administration/Login.aspx with Administration/Default.aspx. I tried editing web.config in root directory by adding the following lines, but it only shows me Login.aspx and it redirects me to the public section:

[Code]....

Do I also have to add web.config in "Administration" folder and with which parameters?

Multiple Applications Using Same Login Database Logging Each Other Out?

Mar 16, 2010

I've set up two ASP.NET applications on a machine, their web.config files contain the same applicationName value in AspNetSqlMembershipProvider item so they share users and roles.

The problem sequence is:

user logs into application A,opens new tab in a browser logs into application B, his login in application A is signed out and vice versa.

Should I use a different approach to sharing login information between two applications?

C# - Design A Database For Templated Logging Purposes?

Jan 30, 2010

In my web application I want to log certain user interactions etc, like "User ABC joined Group XYZ" Therefore I want to set up a logging mechanism that logs into a Mssql database. I'm now trying to find a good database design to achieve flexibility.

First of all, I don't want to log strings like "User ABC joined Group XYZ". I'd like to separate the content "ABC" and "XYZ" from the template. So I'm looking for a templated logging database.

Something like this:
table: UserLog

IDLog int primary key [code]......

I think this database structure would give me enough flexibility to add/remove/edit specific log types (like 'User ABC did something else'). For example I might want to add some information to a specific log entry for future entries. Therefore I create a new UserLogTemplate that references the same UserLogType. That is how I would achieve downward compatibility.

Is that a database design that will work?

Security :: Getting The Login Function To Redirect Depending On The User Logging In?

Oct 27, 2010

I am currently using the built in ASP login function... the destinationpageurl of that login function locates to "loginhome.aspx" for all users... but for one specific user ("Admin") it needs to link to "adminhome.aspx"... just wondering whats the best way to do this? Can I change the destinationpageurl of the login function depending on the user or creating an admin role so "If membershiprole = 'Admin' redirect to 'adminhome.aspx' End If" or can I just add some code behind the login function so "If User.login.Name = 'Admin' Then destinationpageurl = 'adminhome.aspx' End If" think I have already tried this on the login1_authenticate event but it didn't work

Security :: How To Prevent New Users From Logging In Immediately / Account Approval

Jul 17, 2010

I am implementing strightforward membership provider. I do not want new users to be able to login without being approved.

I have tried the setting on the registration wizard called DisableCreatedUser="True" and this does not work.

I also set LoginCreatedUser to False, and the user still gets logged in.

If I look in the SQL membership table, 'IsApproved' is set to 0 for the account, but they can still login.
