How do i set a limit for user to sign up in ASP.NET ?
For example, I'm creating a web application using Microsoft Visual Studio 2008 to make it available for users to sign up for the event. But i only wish to allow 10 people to sign up for that particular event.
So what code/thing i need to do to able to set the limit?

I have a 2 page signup form, on each page the form fields are seperated into sections. Each section is a user control, and there are 2 controls on each page. My question is, how do I get the data from page A to B. I'll be using a webservice to insert the data into SQL so I'm not worried about that portion of the process.

using System.Collections.Generic;
using System.Configuration; [code]....
Is there anyway to detect when a user logins if there is already another session with the same username, and block him from logging in again or send him a message?
View 6 RepliesI have set Private Memory limit of 200mb in IIS 7 for an application pool. The Private Working Set memory(Task Manager) for the application is always below 125mb but the number of page faults have increased a lot and application cache is getting cleared frequently after setting the limit.
I haven't set any limit on Virtual Memory.why the cache is getting cleared even when the Private memory used is below the allocated memory?
I'm building a web app (VS2010, C#, .NET 4.0) and am aiming to make heavy use of objects. One particular object will be a 'user' object. One of the properties I am exposing for the object is the users Status (e.g. Pending, Active, Suspended, Expired). In the front end this status will be editable and I don't want users of the app to enter invalid statuses (Pendong, New, etc.). I could hard code the valid statuses in the front end making use of a radiobutton list or dropdownlist, but that isn't logically where the valid values should be defined, I would have thought that the objects class would be a better place.Now this leave me with two problems:
Which is the best place to define the valid values? If I add them to the class, how do I read and present them in the front end?I'm hoping that you guys can put me straight here. Are any of my ideas architectually correct, or if not then what would be better.
I've got a form that will be used to send an email from a site. I'm using regular expression validators to limit the input to only appropriate characters in all of the fields. There are two things I want to protect against with the body portion of the email, sql injection attacks and the user entering too much text. The body portion of the email is entered using a text box with text mode set to multi line.
What is the best way to prevent the user from entering too much text and to guard against characters I don't want? I assume a regular expression validator will be ok for this. Will there be performance issues with this? Will the regex validator work well enough for this situation? Is there a better way of doing this?
I have several pages or views in my application which are essentially the same for both authenticated users and anonymous users. I'd like to limit the insert/update/delete actions in formviews and gridviews to authenticated users only, and allow read access for both authed and anon users.
I'm using the asp.net configuration system for handling authentication and roles. This system limits access based on path so I've been creating duplicate pages for authed and anon paths.The solution that comes to mind immediately is to check roles in the appropriate event handlers, limiting what possible actions are displayed (insert/update/delete buttons) and also limiting what actions are performed (for users that may know how to perform an action in the absence of a button.) However, this solution doesn't eliminate duplication - I'd be duplicating security code on a series of pages rather than duplicating pages and limiting access based on path; the latter would be significantly less complicated.I could always build some controls that offered role-based configuration, but I don't think I have time for that kind of commitment right now.Is there a relatively easy way to do this (do such controls exist?) or should I just stick to path-based access and duplicate pages?
Does it even make sense to use two methods of authorization? There are still some pages which are strictly for either role so I'll be making use of path-based authorization anyway.Finally, would using something other than path-based authorization be contrary to typical asp.net design practices, at least in the context of using the asp.net configuration system?
I know I can use [assembly: FileIOPermission(SecurityAction.RequestRefuse, Unrestricted = true)] to limit user to access disk files, now I hope to limit user to access database and web.config file, how can I do?
View 2 RepliesI am totally lost finding the right API to create a sign up process like Foursquare. I am attaching a document of what I am trying to do. I have already tried OAuth, JavascriptSDK, Facebook.NET API from Codeplex and FacebookToolkit.NET from Microsoft. Nothing looks what I actually need. I think some one experienced can lean me towards where I should go straight.

I am using forms authentication to protect a website and would like to set it so when someone uses the registration form that the account created is disabled and an email is sent to me notifying me of the new signup. Then I can go and enable the account.
I am very new to this but have gotten the basic registration form and login form working with my SQL 2008 Server but this is a bit above me and I have looked through the MSDN info on the CreateUserWizard and don't see options for this.
I've a Gmail account, assume that me@gmail.com. Now I want to login (as admin) in my website through this account. I know I can use OpenID etc. for that purpose but I want to limit it for just me only. Can I do this? I don't let anyone else to know which service I used to login and what is my address and etc. (Note: My website contains just one and only one login form, for just me, only!)
View 1 RepliesJust wanted to know what is the best pratice for storing new fields data when an user sign up ?
Also...
1- Is there a way to make the login controls use the same database than my website database?
2- It is okay to use the Membership and Role API to manager users from an user interface (without the ASP.NET Web configuration tool) ?
I've been tasked with creating a dorm signup/management application for the University at which I work. The application will have a front-end and a back-end. The front-end will be utilized by students.
Front-End:
A student will login and see a selection of dorm buildings they are eligible to reside in (based on gender, class level, etc.).Student will click on dorm they are interested in residing in. A new set of options will appear - a list of available rooms they are eligible for within that dorm.Student will clock on the room they are interested in residing in. They will see how many spaces are open and who is currently residing in that room. They can then choose to add themselves to the room.Obviously, students will also be able to remove themselves from rooms and navigate backwards and forwards through the various levels - e.g. if they get into a dorm or room and see it isn't what they want they will be able to go back to the entire dorm orthe entire campus.
Back-End:
Administration will be able to assign students to specific rooms and/or dorms.They will be able to set time windows in which certain students, class levels, etc. can select their dorm room. This is the essential functionality of the applicaiton. Pretty simple. I'd like any recommendations on the best way to write this application and anything I might be missing. I've been doing some preliminary work trying different ideas.
I've been using LINQ to tie into the data sources - which seems to be working fairly well. The one area I'm having some difficulties with with dynamic control rendering and event handling. Since the application doesn't know which dorms or rooms will be available until it knows who the student is, the controls need to be generated dynamically.
I have develop a web application. I have put my web application in my server and user can access from any location.
My server regional and setting is English (US). Now my problem is
1) When user access to my system and his pc setting is English (UK), it will prompt and error
and after i debug i suspect it is because of Datetime conflict (dd/MM/yyyy and MM/dd/yyyy)
2) I cannot fix or limit my user to setting his/her pc regional setting to UK
So what can i do in my web application solve this issue?
(Can i write any code in my client side (.aspx) to convert or do standardization to US)

View 7 RepliesI have experienced some troubles when using the IIS server at my workstation with Windows 7. This is a development machine and I don't need to use it as a production server or anything, but for some tests it's quite usefull to see what happens when a lot of requests comes concurrently (in this case even in the same session).
I have learned that with my edition of Windows 7, the limit of requests is 10, but I thought it only means the limit of requests that can be served at any point of time. What I am experiencing instead, is that after firing 10 requests one by one, if the first one didn't complete before the last one was fired, it never completes. The whole IIS is dead, no further requests are put in the worker process queue (there are already 10 requests there hanging so it kinda makes sense) and the only way to go on is to restart.
Is this a standard behavior that cannot be changed on Windows 7 and does firing 10 requests really have to kill IIS (or at least the current worker process) ? Is there some way to change the configuration to fix it (without compromising the setup by creating bunch of worker processes etc.) ?
