View 2 RepliesI need to develop an application, which will get records (orders) from one application and process them. The updates to this records (order updates) will be sent back to the source application for end customer reference. I'm planning to achieve this data synchronization at the database level using triggers and stored procedures to insert database between the 2 databases.
But, the issue is I have to deploy this application in 3 different customer sites and I have to change the database names (cannot use the same database name) in each deployment manually. Because of this deployment issue, I was thinking of handling this within the asp.net application where I can store the db name in the database and then build the query within the application, but I dont want to do it as building queries like that doesnt look very professional.

Controls may be vary time to time according to suitation and aspx page changes all time according to suitaion.
For Example :
I want to display a information about Computer and Technolgy the aspx page will be display only Computer related topics like 1. Computer Name 2. Price 3. Discount
but in other case I want to display information about City Information then Display 1. City Name 2. Distance from nearest city. 3. City Map 4. About City 5. Query or book a car. extra - extra.
In asp.net web application I have restricted users actions depending on their roles like as follow
I have created three tables in database
Tables
Table: Users
UserID Username Password
1 Bob password1
2 Scott password2
3 Jisun password3
4 Sam password4
5 John password5
Table:Groups
GroupID Name
1 Administrators
2 Clerk
3 Manager
4 Cashier
Table:Roles
UserID GroupID
1 1
2 2
2 3
3 4
4 3
4 4
In Global.asax file I have written the following
Sub Application_AuthenticateRequest(sender As Object, e As EventArgs)
If Request.IsAuthenticated Then
'Determine this user's roles[code].....
as of now it is working fine. Now a new requirement has araised that to allow the clerk to access some of (but not all) functionalities perfomred by administrator.
Do i need to change my source code to provide above new requirement?
Do I need to do the same again and again when such requirement araises in future ?
I'm using the jQuery NotifyBar quite nicely in an Index view to display business rule errors when a user e.g. clicks a delete link for an item than cannot be deleted. However, if the user adds a new item, they are redirected to the Create view. If the new item is successfully created, the Create action redirects back to the Index view.
My quandary is that I need (have been told) to show a success notification in the above scenario. Previously, to request a notification while remaining on the same view, I was using return JavaScript() for an action result, but when I use return RedirectAction() for the action result, I'm left with nowhere to put the return JavaScript().
The way I see this is that I need to: a) include information in the return RedirectAction() that tells the 'destination' view to show the notification, or b) invoke the notification in the 'source' view, instead of the return RedirectAction(), and tell it that when it closes/is closed, to perform the redirect to the 'destination' view.

Asp.net 2 or 4.0
We have a controlled list of the users (It s an Extranet solutions for our collaborators)
We need to develop some new web pages (not all) some of which require the user accessing the web page to fill out some form and sign it using his digital signature/certificate. Each customer has their own certificate which he has on his computer (either as a local desktop file or the certificate may be probably integrated into the browser certificates via browser advanced options).
In other words:
1- Allow a client visiting some of the web pages to digitally sign the form before submitting it to our web server (the signature is his specific certificate)
2- Send either the form and the certificate or the html encrypted with his certificate to the web server
3- Read and identify the certificate on the web server (C# code)
I'm starting to plan an architecture for a big web application, and I wanted to get suggestions and/or recommendations on where to begin and which technologies and/or frameworks to use.The application will be an Intranet-based web site using Windows authentication, running on IIS and using SQL Server and ASP.NET. It'll need to be structured as a main/shell application with sub-applications that are "pluggable" based on some configuration settings.
View 3 RepliesI'm designing my first asp.net web app, using nHibernate as the data provider. i've read a lot about nhibernate in web applications using session-per-request pattern. my application will have a few pages which are 'monitors', meaning- they're updated automatically every few seconds to reflect recent changes to data. in that case, my thought is that opening a session for every request would not make much sense, since I know that an identical request is sure to follow in a few seconds. my thought is that session-per-conversation would make more sense for me, but I'm having trouble finding examples of implementations. I'd appreciate any good resources for how to implement session-per-conversation

View 3 Repliesi am new in asp.net. i have create a website. its related to tours and travels. Now when any customer get login to webportal then the login info of that customer should send to my system i.e. website. here it will check the user is valid or not or new according to that check user's permissions and send the data to the webportal.
then customer can search the specific data and book the some data say 'hotel'. that time the booking information should send to back to the system. so my query is how can i send the information from my system to webportal and vice versa...(can i do it with javascript)
I'm trying to create my first Asp.Net application from scratch. Tried to create this post in some of the other forums but I couldn't find a better place.
So, as the title says, I'm having trouble trying to model my application. I'm like an OOP newbie. I'll show my classes first and then I'll write my questions.
Model Layer
public class User
{
private int id;
public int Id { get { return id; } set { id = value; } }
private string login;
public string Login { get { return login; } set { login = value; } }
private string password;
public string Password { get { return password; } set { password = value; } }
}
Data Access Layer
public class BasicDAL
{
private SqlConnection connection;
//>>Returns a new connection to the database
public SqlConnection GetConnection()
{
//>>If connection is active close it before starting a new one
if (connection != null)
if (connecion.State != ConnectionState.Closed)
connection.Close();
connection = new SqlConnection("MyConnectionStringHere");
return connection;
}
}
public class UserDAL : BasicDAL
{
//>>Insert a new user
public void Insert(User user); { /* Insert into DB */ }
//>>Authenticate user login with its password
public void Authenticate(User user); { /* Authentication code here */ }
}
Business Logic Layer
[Code]....
So, model layer is pretty simple. Just a user representation. On the Data Access Layer I have a basic class with a GetConnection method. All DAL classes will extend this one.
My first problem lies on Business Logic Layer. With the above scenario, I've placed the same methods that I placed at the DAL. BLL methods would call DAL. As simple as that but I believe It is not the best way to do it, is it? How can I improve those classes?
Also, I have to "try..catch" blocks. That's because I can't find good places for it. I mean, if I place a try..catch on GetConnection method, for instance, how my ASPX page would get this error? How my ASPX page can tell the difference between "database offline" and "sql syntax error" when executing "userBll.Insert(newUser);".
My problem is mainly placing the exception handlers. I understand I would probably have to change return type of some methods. I didn't change because I believe that will have something with the exception handlers.
Btw, please assume I can't use TableAdapters and stuff like that. I would like to create all layers by myself.
I'm starting to think about and develop an architecture for a big web application, and I wanted to get suggestions and/or recommendations on which technologies and/or frameworks to use.The application will be an Intranet-based web site using Windows authentication, running on IIS and using ASP.NET. It'll need to be structured as a main web application with sub-web applications. Essentially, the entire scope is a composite browser-based,Intranet application that is composed of discrete, functionally complete modules or sub-applications.
