I am involved in designing a asp.net webforms application using .NET 3.5. I have a requirement where we need to log exceptions.
What is the best approach for exception handling, given that there would be concurrent users for this application?
Is there a need or possibility to log in exceptions at a user level? My support team in-charge wants to have a feature where the support team can get user specific log files.
To give you a background, this application is currently on VB 6.0 and we are migrating it along with some enhancements. So, today the support personnel have a provision to get user specific log files.
I have a application, and I want to log exceptions to a file and I don't want to change any code. I just want a component to which I can add my code and it will start logging exceptions. How can I do this?
I need to know, whether extjs 3.1 is available of exception handling and logging build in library .Like Logging the exception as log file , with the specification of error whether it is major or minor or critical or info.new log file creating on specified size exceeded. etc...
I have a form that's used to submit emails for a project. This uses the SMTP Client class and is currently delivering the emails to a local directory , for now.
There is some logic that checks to see if a mailbox is busy or unavailable. A message is displayed for the appropriate situation. There is also some logging and exception handling.
I want to know if there is a way to test this logic, logging and exception handling while this app is local. I don't know if there is a SMTP Status Code that's returned since this is being done locally and not with a real smtp server.
Is there a way to test this locally? Can these values be set manually in the code as a test?
I'm developing web application with concurrent user using the application. The problem i'm facing is that if the first user login his details are taken affecting the second user how is process the data in the application.How to avoid it?the best way to code to maintain concurrent users.
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?
If multiple users access a web-form at the same time, how can I allow that using my code? Essentially each user reads and writes one variable in the application, and concurrent access is causing problem there.
In my ASP.NET MVC2 web app I have a page which goes off and gets results from a number of different web service feeds. These return times vary so I want to basically display them as they return after the page loads. I also want my user to be able to kick of requests that can run concurrently with these other requests.
At the minute my page just seems to queue up the requests. The web service calls returning one at a time in the order they are called and then the user can kick of requests.
Is this a case for the asyncController or is there an easier/better way of working this?
My application is windows authenticated. The application pulls JUST the userName from the current windows account. Then I provide site access to this user depending on his account privileges. If his userName belongs to the admins list he is directed to admin screens. If his username belongs to users list he is directed to users screens. I handle this security in C# and some SQL tables(No membership provider and no Active directory security in the app).
I need to be able to prevent multiple concurrent logins for the same userName.
I am using asp.net 2.0. I have been using asp.net membership provider for user management. But I think this would be more efficient if I could do this without using role and membership provider provided in asp.net.In fact I see bulky markups generated when I add login control, createuser control etc. in an asp.net web page.By saying user management, I am referring to the overall login, user activity tracking, password reset/retrieval, role management in an asp.net web application. And I want to implement efficient way to accomplish this.
I am working on a 3-tier asp.net application. Currently I'm stuck up in a situation where I need to handle a specific type of exception (User Defined) in DAL and Show alert to the user if that exception occurs in DAL.
I tried following things:
1) I raised that exception from the DAL and catch it in BLL and throw a new BLL exception to for that DAL exception and finally catch it in the UI layer to show the alert to the user. I've successfully implement this in my project. But there are some issues in this approach. First of all I feel this is not right way to do this as it may lead to performance related issues. Secondly, the application contains more than 500 pages and classes. so I need to attach additional catch block in every method to catch the BLL exception. which is the last option i'd like to take.
2) in second approach I logged the the DAL exception into a text file. but problem in this approach is that how could the UI layer know that exception has occurred and show the alert to the user. Is there any event in asp.net where i could handle all this activities?
my question is what is the best approach to handle this type of situation? Will Exception handling block help me in this?
I've tried reading many articles on this but i couldn't get an answer for my question? I might not be using right keywords for my search.
I was adding login and logout functionality to my ASP.NET website. While I am able to make the user log in by checking the username and password but on some pages should be available only if he is logged in. I am doing this by storing the user's value in a session
Secondly, I am using a Link button which changes to Logged in as example. So, how does the user log out?
Im building a web application that charges for access on a per user basis. Ive used standard roles and membership for setting up accounts and logging in. I want to ensure that a client cant use the same user details to login more than once
ie if user abc1 is already logged in, someone else cannot login again using the same credentials
FormsAuthentication.RedirectFromLoginPage(txtUser.Text, false); After doing this, the user is logged in with the txtUser.text
But the question now is, how do i retrieve that user name from Authentication or whatever on other pages? is it possible or not?
Because i know that person stays logged in untill he logs out with this code: FormsAuthentication.SignOut();
And one more question i dont know is this one good for this or not how do i better check if the person is typed in correct name and pasword or not, with executescalar or executereader?
I have a login form from the membership and I am trying to make it so that it would redirect depending on role. I have tried to put this code under login1_loggedin but it didn't seem to work. how can I do this?
So its a ASP.NET problem where two users using the same machine, same browser:
User 1 logs in the domain. User 1 changes some data without saving it. User 2 logs in the domain in a separate tab. User 1 switches back to his tab and saves the data. User 1 actually saved the data into User 2!!
This is caused by the following mechanism:
Different tabs in the same browser seems to share the same session id.
We are storing user auth in cookie and the cookie is shared between tabs (same domain)
Therefore, when User 1 request to save, it is recognized as User 2 since the cookie has been updated to User 2.
So I'm wondering if there's any other methods to prevent this from happening, other than:
1. Use cookieless session so the session is embedded in uri. 2. Always include a hidden field in page to indicate which user owns the page.
I spent a day trying to make Ent Lib Logging work and log anything into database or event log. I have a web application and console application with the same Ent Lib config but only the console application is capable to log into the Event Log. I tried everything with permissions but I don't know what exactly I am doing — which services should have what. It does not work!
I read articles like this[URL] and I want to try to give the ASPNET account those permissions. I am using Windows 7 and I cannot find ASPNET user account. So where is it?
This is the config file which is automatically generated from Ent Lib utility and it works only on App.config, not on web.config:
When a user logs in into my website I have a custom membership provider that overrides ValidateUser and verifies that the user has sufficient rights etc.
However, when implementing a 'remember me' function through the default forms authentication using RememberMeSet, I also want to validate a user on the first request.
Is there some hook I can attach to that triggers when a user logs in with their persistent cookie?
I am using asp.net membership and the login control. I would like to prevent a user from logging in with the same use rname if they are already logged in. I would like to place code in the LoggingIn or Authenticate event of the login control to check whether the user is login and prevent them from logging in again. Any ideas on the best way to do this?
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
