ASP.NET Login Script authenticate and role based with MS Access DB and SQL
Hi
First of all i making this thread bc. im new to this and not a pro.
And bc i used 4 days searching the net for help/solutions/tutorials on this, but i dident found any 100% solution.
In this (My first code snip, inhere) i will show a solution on a Login Script in ASP.NET VB, using MS Access DB and SQL DB, with Authenticate and Roles.
(SRY MY ENGLISH)
As i write i used a lot of time searching the net for a solution on this but i dident found one, and i HATE the login script provided with the ASP.NET in Visual Web Developer 2010 Express. (VWD2010E)
I need a login script where the users was saved in a DB and where i can give my page some Roles so an User cant see the same things As a Manager or Admin.
I thread in here was http://www.vbforums.com/showthread.php?p=4201896
In here i tryed to request help but dident get it and i think its bc the other users dident know, that i was not a pro and dident have the education so some of the things i got in feedback i dident understand.
So if u a Noob like me, then i hope u can Use this Code Snip, The code is working, and i have used some code from other tutorials, so i know that some things can be edit and maked better, im looking at that and if other have some fix/edit to this code, then PLZ. come with it.
I used these link as tutorials.

Now to the database.
- Start a new website inside VWD2010E, i used VB and started a new ASP.NET Empty Web site.
- Add the Folder "App_Data".
- Make one of these database in the "App_Data".
MS Access DB
Call the DB LogonDB.mdb
CREATE TABLE Users
[UserID] PRIMARY KEY, AUTONUMBERS , NOT NULL
[Username] [varchar/Text] NOT NULL
[Password] [varchar/Text] NOT NULL
CREATE TABLE Groups
[GroupID] PRIMARY KEY, AUTONUMBERS , NOT NULL
[Name] [varchar/Text] NOT NULL
CREATE TABLE Roles
[UserID] [Int/Numbers] NOT NULL
[GroupID] [Int/Numbers] NOT NULL
SQL DB
Call the DB LogonDB.mdf
CREATE TABLE Users
[UserID] PRIMARY KEY, AUTONUMBERS/INT , NOT NULL
[Username] [varchar/Text] NOT NULL
[Password] [varchar/Text] NOT NULL
CREATE TABLE Groups
[GroupID] PRIMARY KEY, AUTONUMBERS/INT , NOT NULL
[Name] [varchar/Text] NOT NULL
CREATE TABLE Roles
[UserID] [Int/Numbers] NOT NULL
[GroupID] [Int/Numbers] NOT NULL
Then insert the data to the DB u are using.
Users
Username = user1, user2, user3
Password = user1, user2, user3
Groups
Name = Manager, Admin, User (U can make whatever u want here)
Roles
(here u are using the UserID from Users and the GroupID from Groups)
UserID 1, 2, 3
GroupID 1, 2, 3
Here i want
user1 to be Manager
user2 to be Admin
user3 to be User
And if i have an user4 maybe he/she need to be Admin to then i will add
the UserID for that user to Roles in UserID and then in GroupID inside Roles i will write 2, then the added user will be an Admin.
Okay now to the code.

[RESOLVED] ASP.NET Login Script authenticate and role based, with MS Access DB and SQL - PART 2.
Now to the Default page, here i have used 3 ways to show diffrent parts to the user, depending on the role the user have, i have user User.IsInRole in 2 ways, Response.write() and then somethingid.Visible = True.
On that way i can see things only for Managers, Admins og Users.
Then i have another way to show things its with the asp:LoginView RoleGroups. here i can make maybe a link that users cant see, but Managers and Admin can see the link.
So 3 diffrent ways to show sensitiv things.

If u need this to work with MS Access then u need to changes this
..
<connectionStrings>
<add name="SQLConnstr" connectionString="Data Source=.\SQLExpress;Integrated Security=true; AttachDbFilename=|DataDirectory|\LogonDB.mdf;User Instance=true;"/>
</connectionStrings>
..
With this
..
<connectionStrings>
<add name="AccessConnStr" connectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|\LogonDB.mdb;Persist Security Info=True"/>
</connectionStrings>
..
Remember to add authorization for folders or pages that need to be used with the login script, here i think on CSS files in a folder like "ADD/CSS/" u will not use the folder in the header of ur login/default page if u havent added the folder to ur web.config.
<location path="FOLDER or site.aspx">
<system.web>
<authorization>
<allow users="John"/> // allow John ..note: you can have multiple users seperated by comma e.g. John,Mary,etc
<deny users="*"/> // deny others
</authorization>
</system.web>

I hope u can use this, im new to this so i cant make a description on why and why not, bc. i will not write something thats not true, but this is working 100% and again some of the things can be maked better, and if u see something and have feedback then PLZ. come with it, so we can make a better code.
But this way my add/Code Snip to this page, about making a Login Script using MS Access DB or SQL and then still can use Roles, so u can show diffrent things on the page depending on the user Role.
PLZ. Rate it or give me feedback and changes that can improve the code and then again SRY my english.

Re: ASP.NET Login Script authenticate and role based with MS Access DB and SQL
Thank you very much for the code! It looks awesome and simple to employ! HOWEVER, I'm receiving and error with everything installed. I removed this, tried again and received another error (which I will post if necessary). Thoughts?
Code:
Configuration Error
Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.

Re: ASP.NET Login Script authenticate and role based with MS Access DB and SQL
What version of ASP.Net are you using?
The targetFramework attribute of the compilation element only appeared in ASP.Net 4.0:
http://msdn.microsoft.com/en-us/libr...v=vs.100).aspx
If you are using anything earlier than this, then it will throw the error that you are seeing.
