C# - Login - Allow Only 3 Attempts?

Oct 21 10 at 13:37

I am creating a new application..I created a login page successfully..Now I need to modify the login page ..Only 3 attempts only allowed for a user ..If the user wrongly enters the password more than 3 times(within 5 min) his account must be blocked..And error message must be shown as You cant access your page.


Unsuccessful Login Attempts

Jul 29, 2009, 16:52

I am fighting the ASP.NET membership system. Every time I try to login, I get "Your login attempt was not successful. So I checked the membership table and found that my FailedPasswordAttempts increased by 1, and that IsLockedOut is "False". My application name is set to "/" in the aspnet_Applications table per the multitude of articles/posts instructing developers to do so. One thing that seems very strange to me is that there is no autogenerated <membership> section in the web.config file. So I put one in - but to no avail. Same error, no noticable differences in application behavior. I am running this on the local machine. Membership login was working earlier today and stopped working soon after I applied a rule to the root folder that was Deny All for all users (oops?) I deleted that rule, but that didn't help. (Could the rule still be applied to some folder?) I am kind of scared to deploy an application whose membership system might suddenly stop working.

C# Multiple Login Pages Based On Which Folder User Attempts To Access?

Jul 15 10 at 14:57

I have developed an application in ASP.NET 3.5 which utilizes the Membership and Roles Providers and Forms Authentication to manage user access and profiles.

There are various area's of this application that are only to be used by an admin users whom login using their email and password and the rest of the users log in using their telephone number and password via their iPhone.

For simplicities sake, I would like to have two different login pages, one that is formatted for the iPhone and performs the correct validation for users adding a telephone number and the other for the application administrators.

I want to redirect the user to their respective login page based on which folder they are attempting to access. For example say I have an application structure like this


I want to be able to redirect users who go to [URL]/Whatever to iPhoneLogin.aspx and users to go to [URL]/Admin to adminLogin.aspx

Configuration :: SQL Server 2008 - Can't Get Connection String Right After Many Attempts

Mar 08, 2011 06:51 PM

I have a new server that I am attempting to deply my very first asp.net website on. I have installed SQL 2008 r2 and loaded my DB on it. I am able to access the server/DB through Visual Stuidio. At least I know i can call it from the webserver to my local PC.

For some reason I just cant get my we.config's connection strong right. It might even be the <provider> info that I have wrong. I am just too inexperienced to know for sure. My Web.Config is very short so I will post all of it here.

-- Code is posted at the end --

How do I modify my local project to use my webservers DB instead of the standard SQL Express DB? The only connection string

Machine.Config that points to the sqlexpress database. Again I lack the experience to know how to do this. I am using Visual Studio 2010 and SQL Server 2008 r2 on my local pc.

Security :: User Account Was Locked With NO Recorded Failedpassword Attempts?

Feb 22, 2011 12:03 AM

user phoned me and said he received an error when attempting to login stating that his account had been locked. I had to unlock the user account today manually through the user interface. Several hours later I had to do it again. Afterwards, when I looked at the aspnet_Membership table it showed NO failed login attempts. LastLockout date for that particular user was set to min date. FailedPasswardAttemptCount was zero. FailedPasswordAttemptWindowStart was min date. I then proceeded to fail logging with the users account name.

State Management :: How To Block The UserName After 3 Invalid Password Attempts

Jun 17, 2010 10:23 AM

Iam very new to this forums as well as ASP dot Net...i was succesful to write this code in 3 to 4 ways but im not getting using the below method.

here it goes...

Task Name : Disable User Name after 3 invalid Password Attempts using "SESSIONS" & "VIEW STATE" with SQL Server as Database i want code in "C#"

In Detail :

When i Enter a User name and Password correctly and click Login it will Re-Direct to Destination Page.

But when i enter same User Name but invalid password 3 times then the user name should be blocked (After The User Name has been blocked the user will send an email to Admin that my user name has been blocked so Reset etc etc and the Admin will Reset The new Password)

Here Create the User Name & Password In SQL Table Directly. As We give the user name & password to users...also create another column in Table for an integer so that when it hits to 3 it should block the user name and also another column for status.

For Counting the values till 3 donot use static integers..instead use SESSIONS also use VIEWSTATE

C# - Custom MembershipProvider Attempts To Pass Empty Creds After IIS Restart

Mar 12 10 at 18:47

I have a C# custom ASP.Net MembershipProvider. When the user attempts to navigate to another part of the site after IIS is restarted, it doesn't navigate to the login page to collect credentials, but instead attempts to authenticate with empty credentials.

what I have to do to identify that the new authentication needs to take place and that new creds need to be gathered?

I have a complementary custom IHttpModule implementation that allows me to intercept events like BeginRequest and AuthenticateRequest, if that helps.

Visual Studio :: VS2008 SP1 Attempts To Connect To Time.windows.com When Starting Applications

Feb 13, 2010 06:10 AM

My workstation does not have Internet access, but it uses a DNS server on the LAN. Every time I start any ASP.NET application from Visual Studio with either F5 or Ctrl-F5, the workstation (I don't know whether it's Visual Studio or Webdev.Webserver.exe) asks the DNS server for the IP address of "time.windows.com". The application is not started until the LAN-only DNS server returns an error, which results in a 10-second delay, during which the Internet Explorer is started, but displays a white background. Is there any way to prevent these connection attempts?

Security :: Allow Clients To Login To Website And Connect To Specific Server Based On Login

Jul 05, 2010 10:08 PM

We have created a windows application which is distributed amongst our clients. The application uses SQL Server 2008 as the back end and each client uses their own database on their own server. The databases are all exactly the same but each clients data is specific only to them.

We would like to offer our clients the ability to log-in to our website which would then login to their own database so that when they are out in the field they can perform similar tasks to what they can do with the windows app.Each of the clients databases has a user table containing their login details, permissions etc.

Our server is running on IIS and has SQL Server 2008 installed but it only contains our data and nothing of the clients.How should we go about this?

What I mean is do we need to make each client have an additional login to our main server which would then hold each clients individual connection strings etc which would then be used to connect to there specific database and then they would need to login again?? Seems like a nightmare for the user.

C# - Convert The Standard Login Framework That Ships With MVC 2 Into A Modal Login Dialog System

Oct 17 10 at 1:44

I'm trying to find an example of how to convert the standard login framework that ships with ASP .NET MVC 2 (the account controllers and views, etc) into a modal login dialog system, like the one at Digg. After searching for hours, the closest tutorial I found was this: [URL]

However, there are a few modifications I'd like to make to it--such as, if there is a validation error, instead of displaying it inline on the form (ex: <%: Html.ValidationMessageFor(m => m.UserName) %>), I want to slide down a bar at the top of the page like Twitter/Digg. I'm not sure how to make use of the existing authentication framework to access the validation errors in javascript.

Security :: Secured Site Using The Login Control / Do Not Want Them Redirected Based On Their Login Status?

Mar 24, 2011 04:03 PM

I am doing a simple secured site using the login control. I would like users to be redirected to their dashboard page once they log in, but after that if they choose to browse I do NOT want them redirected based on their login status. I am using the generic template provided in VWD with the basic login setup in the template including the tabbed ASP menu control - nothing fancy, nothing custom. This is intended to be something very simple and quick. Here is the code I am using for the page load...


So if I do this code WITHOUT the "IsPostBack", logged in users are always redirected to their dashboard and cannot see the hompage. However with that IsPostBack test, the redirect after initial login doesn't work.

I know this is extremely basic and simple, but I am restarting with this stuff after a year away, and I need a nudge.

I go to the create user page, add a user.

I can SEE the user on the database using Server Management Studio...

I go to signon and get "Your login attempt was not successful. Please try again."

I have not customized the login control in any way. (OR the createuserwizard)

HOW can I tell where the Login tool is going to get userid and password info?

How can I tell if it is not finding the user or the password does not match?
