View 4 RepliesThere is an ASP.NET application www.example.com/APP. From within the application several documents - for example office documents DOCX, PDF, etc. - can be opend. They are accessed via some virtual directory as in
www.example.com/APP/VIRTUAL/letter.pdf.
Of course, the documents may only be accessed from within the application, after the user has been identified succssfully. Some documents may only be opened by some privileged users. It should be impossible to open letter.pdf by simply entering the above url into a browser
I am thinking about the following...
The name of the virtual directory is kept secret. After the user has successfully logged into the application, some secret is created. The secret contains the user's ID and some time information (valid from / until). Then, if a document is to be referenced from within the application, the url www.example.com/APP/<secret>/letter.pdf is referenced. In IIS the secret is checked. For this, some of my code is called, when serving a request. If successfull, the url is rewritten as www.example.com/APP/VIRTUAL/letter.pdf. I tried several components, such as the IIS URL Rewrite, IHttpModule, IHttpHandler. Unfortunately, I did not yet succeed.
I'm building a web application that most allow the user to digitally sign PDF documents with certificates installed in the client machine.
The document, once signed, should be posted back to the server, where it will store the signed version.
The server is running Classic ASP/ASP.NET
I have an application with several web pages. I am developing securities for those web pages.
Thus, I would like to create a dropdownlist that reflects the various aspx pages, or files inside my application. I would prefer that it reflected the aspx pages only and avoid the .cs files and config files and etc. I'm not even sure that this is possible. Is it? If so how? if I can't filter like that I would still take it.
I have an asp.net web application. I don't have the source code. The bin contains 10 assemblies and a .compiled file. I used Reflector on the App_Code.dll and it shows me classes and namespaces and stuff, but its such a mess.Is there any way to reverse engineer this web app that won't take weeks/months to unfold? The application is pretty basic.
Note, the code is written by an engineer that left the company. We own the product.
At the moment i,m working at a websit (ASP.net 3.5). I have build the project and till my surprise it is possible to reverse engineering the created dll's to the code (with Red Gate's .NET Reflector).
I have found several tools like Xheo and dotfuscator, but does there realy protected the created dll's ?? Does Microsoft have build a method to secure this ?? If this is not possible everybody can steal your code....
I have took a lot of time reading about this article, but is there a method or tool to make this secure?
I need to auto update application like in wordpress, Application must check if new updates are available, download this updates and install.But I don't know how to install application.

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.
reverse engineer the code and create class diagram in visual Studio 2008 frim visio 2003.dont want to use any external tool.

View 5 RepliesI have an Interface that has its concrete class defined via a factory. Because of this I found no way to use the Interface tpye directly in my LINQ quesry so I had to use the concrete class types to creat a generic list. The LINQ query works but after calling.ToList() on the LINQ query result I get a List(of MyConcreteClass), but I need a List(of IMyConcreteClass). I have tried everything I can find: .Cast, Ctype, implicit casting, etc. but I always get back one of the (2) messages (depending on if I attempt to cast)message:
"Unable to cast object of type 'System.Collections.Generic.List`1[MyConcreteClass]' to type 'System.Collections.Generic.IEnumerable`1[IMyConcreteClass]'."
...or
"Unable to cast object of type '<CastIterator>d__aa`1[IMyConcreteClass]' to type 'System.Collections.Generic.List`1[MyConcreteClass]'."

I m sure this question has been asked before. I have a web application hosted underhttp://localhost/abc. which is mapped to c:inetputwwwrootabc folder. I have APP_Code, App_LocalResources, BIN and other folders under abc folder. Everything is great. Now I want to create another application or sub application
http://localhost/def. Both abc and def apps need to use some common classes and resources. Whats the best way to do it. I dont need to create a separate application for def. All i want is the url
http://localhost/def.
I am beginner in MVC architecture, how to use MVC architecture in Web applicaion?
View 2 RepliesI'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.
