I'm writing an application which has user authentication system, basically, when the user open the software, he has to enter his/hers username and password which are retrieved form a access data base, and if the user is set as admin then it enable some features, I couldn't figure out how to read the column lets say, IsAdmin table, which will store an value of 1 or 0 for example. I need a concept of how build a login system with levels or whatever you guys call it...

Username:
Password:
Login
Create Username
Exit
The login button
If TextBox1.Text = "Admin" And TextBox2.Text = "ABC123" Then
Police.Show()
Me.Hide()
[code].....
That it saves the Username and Pass so the next time I login, it can use this Username and Pass.

I created a Login system using the Login Form from VB 2010 and connectected to a DB table called "Useri" with 4 columns: "ID_U" , "UserName" , "Password" , "UserType". The login form works to authentificate user, and my application starts. My app has 5 buttons and i want them to be restricted by user type
If admin - full acces
if Operator - 1 button(that leads to a form with 4 textboxes that edit a row from a database)
if guest - 1 button that leads to a form with a datagrid
So, if a guest user clicked a resticted button a msgbox appears.
My login form code looks like this.

I'm creating an app like a CRM ( Costumer Relationship Managment ) for a school but I have some questions I'd like to be answered.
It will have a main user ( Administrator ) and that user can create another users to access the app. The app will work locally and I would like to know a method to save that information @ localhost without being acessible to edit or view by other users.
Im thinking in a Access DB with all info and then make all information needed. But how to secure it without anyone else could access it or modify id? An encryption method would be the best way?

I'm using Visual Basic Express 2010 and SQL Express 2008 in Windows XP. At first I couldn't add a datasource (the .mdf file for the database) because of a "Operating system error 32" which I seemed to have resolved by giving myself full permissions for .mdf file (by right clicking on the file and going into properties and then Security) and restarting the SQL SERVER (SQLEXPRESS) service. The dataset for the database is in my solution explorer but when I right click on a table adapter to add a query and attempt to open up the query builder, I get the error in the title above.

Hi, I've created a login screen for my application and defined the username and password using the following code
If UsenameBox.Text = "username" and PasswordBox.Text = "password" Then
Me.Hide()
Main.Show()
It works great however, I need the user to be able to set their own password using a registration form with the details being stored in a xml file. There are no security concerns with the password being stored in a text file as it's a mock login screen.

Is there a way to set session variables during login that are then available to reports? We have a reporting services server where we move and denormalize data from our transaction system for reporting purposes. In order to allow our users to login with the same user name and password from the transactional system we have set up custom forms authentication and after much trial and error it is finally working. In addition we have the authorization accessing our transactional system so that any changes in user authority is immediately reflected in Reporting Services.
Our problem now is that we would like to add some additional features such as locking down parameters depending on user authority/groups in our transactional system. We have found a way to do it but it's inefficient, basically we have stored procedures that will query our transactional system to check for access. The problem is that these queries will often be run for every report request even though the answer is unlikely to change. It would be nice to have access to session level data that can be set once during log in and then accessed from the reports.

I created a SQL DB named MainDB.mdf and a small VB 2010 application with some forms and datasets.Everything was working OK until i got a new computer and re-installed Visual Studio 2010 and SQL server 2010 on it. I copied my DB from the old to the new computer and also copied by VB 2010 project to it. I used Windows Authentication to connect to the DB in the old computer and also in the new one, i am using different Windows user account names though.
I was able to connect to the DB in the new computer in the Server Explorer section, i created a new connection string to the DB and i can seed there is data in the tables. When i run my VB 2010 application created in the old computer get error:
"Cannot open database "MainDB" requested by the login. The login failed. Login failed for user 'D630Admin'."
I need to get rid of that error and be able to add/mod/del data from my DB using my VB application as i used to.

I have been trying to solve this for 2 days now, every text book I own and google have been well and truely exhausted and I am still no closer to solving my problems.I have a login facility reading in user info from a main user file. This takes all info into a temp array and then splits usernames into a username file, passwords into a password file and a current score in a score file.
I have the login working fine and everything else in my program works as intended but touching up cosmetic aspects I want to add a Message box after login to say hello and display current score. This works great for the first name in the user file i.e - after login User1 welcome to the game. Your current score is 45 As intended.But the problem arises with any other users, my message comes out as
User2 welcome to the game. Your current score is 55 I do not understand where the random new lines are coming from. I have tried assigning the message as a variable and removing new line using

This is for a game i've been working on in C# & XNA. I'm not asking for code however, so language doesn't matter. I've got a console. I want to store up to the last 5 messages sent so the user can scroll through them. Additionally, I want to store whatever their message was if they hit up to go through the messages, so if they hit down again they have it back. If they send a message without going back to that, it's lost. I'm not really sure what a good implementation for this might be. I'm thinking a string array where the last value gets deleted each time a message is sent, and a separate string for the current message.

We don't want to get the password, we only want to store the user credentials so when they do work on the application we can apply their usernameto each operation and when they are done with an operation and do a digital signature by scanning their badge we want to compare the user's credentials with the stored credentials to ensure the user has logged in and is the current user.1. User 1 logs into the program using their username/password for windows.5
