how to create a snk for all existing dlls(multiple) in n-tier ASP.net application?I have created a asp.net application using n-tier. My web layer contain refrences of all layers(data,facade,core,common).but when I try to create strong key of web layer it throws error as "refrences assembliy can not have Strong name".
View 4 RepliesI have a web site project in which my architecture is n layered architecture.I am using Micorsoft Enterprise library's validation dll.As of now this dll is not strongly named. I need to make that assembly strongly named. how can i do this.I saw some articles which depicts how to create strong named assembly by taking the vs 2008 command promtp and type sn -k publickey.snk, and then add the assembly tag to the assemblyinfo.cs. I tried to do that, but my website project dosen't have any assemblyinfo.cs file.

View 3 RepliesI have a project due for my Visual Basic course. The project is creating a web application. I'm setting up the application where the user will enter information in a textbox. I want to be able to test the value entered in the textbox. There are three test conditions - less than a certain number, between a range of numbers, and greater than a certain number. I'm familiar with Visual Basic but not that with Visual Web Developer. I want to display a message to the user that tells them the value entered is low, normal, or high, and display additional information. The question I have is can I attach three validation controls to a single textbox? I know how to attach one validator control, and that works fine. I try to attach three controls but when I run the program all three error messages display, which is not what I want. I think I would need to code a custom validator but not sure how to do that.
View 3 RepliesI am using Reporting Services to render a report directly to PDF. It requires that I use two web references: ReportExecution2005.asmx and ReportService2005.asmx. The performance on web references seems really poor. Since my web server (IIS7) and my SQL Server (2008) are on the same box, is there a way I can reference them directly? If not is there any way I can explicitly cache them or something. First load is really really slow, second load is perfectly acceptable.
View 2 Repliestrying to switch to better coding practises, I am totally confused about which path to choose. For the past year I was just coding through classic asp coding methodology. Now I know about things as
3 tier custom 3 tier with Strongly typed data sets N tier applications Custom entity objects and so on
Can someone recommend me an approach for designing web applications from these? Some book or tutorial reference with simple CRUD application that would help me. I am currently stuck with strongly typed data sets as I cant find CRUD tutorials with that approach. I would like to just choose the right approach and build on it.
I have a web application that dynamically loads assemblies based on database configuration entries to perform certain actions (dynamic plugin style architecture).The calls to the objects are in a Factory Pattern implementation, and the object is cached (in a static dictionary<> within the Factory) as the calls can be made many thousands of times in a minute.The calls to this factory are made from both the main web application and a number of webservices, some in different assemblies/projects.When I need to update one of these DLLs, I have to recycle IIS to get the DLL released.As this has an impact on another application on the server, I wanted to know if there was a way I could release the DLL without restarting IIS?

View 3 RepliesHow to create the DAL Layer for the 3tier Architechture
View 1 RepliesI'm trying to decide which of the two factory patterns I should use in my Asp.Net applications:
1 : All DAL providers derive from same abstract base class DepartmentsProvider, which defines public interface of the class ( all the necessary CRUD methods for which derived classes (providers ) provide a concrete implementation ). BLL layer instantiates correct provider by calling DepartmentsProvider.Instance:
public abstract class DepartmentsProvider
{
static private DepartmentsProvider _instance = null;
/// <summary>[code]....
In first case we implement new provider by deriving from DepartmentsProvider class, while in second case new provider is implemented by deriving from DBProviderFactory. What are pros and cons of each implementation?
I' am trying to write a aplication using a 3 Tier Model
Data Access Layer <--> Business Logic Layer <--> Presentation Layer
But now i am facing a problem, i need to Handle Transactions i already found a interesting article
[URL] but i have some doubts.
For example when i need to iterate to a Grid in the presentation Layer how will i Use the Transactions??

I want to develop a three tier architecture app.I have no idea when weplace our BLL and DLL code in different server how to connecct this BLL and DLL code to our Website(UI).
View 4 RepliesSay you have a form designed in Silverlight(Front end)-Asp.NEt(business layer)-SQl(bakcend)Should data validation occur on all 3 layers or just the presentation layer or a combination of the front end with the other 2 e.g. validating an email address? I'm trying to undestand as to why if data has been validated on the presentation why further data validation would be necessary especially if there would be large amounts of data being validated and this could potentially slow down database transactions?
View 4 RepliesI have an ASP.NET project which is pretty n-tier, by namespace, but I need to separate into three projects: Data Layer, Middle Tier and Front End.
I am doing this because...
A) It seems the right thing to do, and
B) I am having all sorts of problems running unit tests for ASP.NET hosted assemblies.
Anyway, my question is, where do you keep your config info?
Right now, for example, my middle tier classes (which uses Linq to SQL) automatically pull their connection string information from the web.config when instantiating a new data context.
If my data layer is in another project can/should it be using the web.config for configuration info?
If so, how will a unit test, (typically in a separate assembly) provide soch configuration info?
Well i want to know how many architecture approaches we can use in asp.net web application. i was asked about it. i told him that i use a appcode for dal and bal and the presentation layer. but he was not convince. basically i want to ask what web application architecture an asp.net web application guru would use keeping in mind the different metrics ( i am talking minus web services or any SOA thing)

View 1 RepliesI have question about N-tier architecture. everyone about 3-Layer architecture these are:1). UI Layer, 2). Business Layer, 3). Data Access Layer.i already have worked on this.Then i heard about LINQ to sql. please tell me how many layer an web application should contain. As my knowledge. if i use LINQ to slq then i have to worked only 2-Laye
View 9 Repliesbut i have a problem to retrieve value from the database in the textbox using 3-tier application. ]
in the App_data i have following folder.
1> employeeBAL in this i have 1class file called empbasicinfoBLL.cs
2> employeeDAL in this i have test_data.xsd
in the basic details folder i have one page Basic information(employee basic info) in this i want that when user will log in the site [using username and password] after successful login when user will click on the Basic information then he will able to see his [name, employee no, first name, last name] etc on the page [i don't want to use grid-view to retrieve the details becoz i am using the table in this i am using Lable and Textbox for each] and this data should come from the EmployeeBAL.
I am upgrading and re designing my current ASP.NET 2.0 website to ASP.NET 3.5 to take advantage of the 3.5 feature set.As part of the re design I am going to use Linq to SQL classes.
The web based application I am working on is an N-Tier application. In the past I have always used an ObjectDataSource when binding against UI controls.I just read an article about the LinqDataSource.After reading this article I am toying with the idea of using the LinqDataSource for selecting data into controls where I only want to select and not change the data (i.e. drop down list boxes or gridviews that don't perform inserts,updates or deletes).Before I go down this path,I was wondering if this is a bad idea and that I should just stick with the ObjectDataSource?
I have a separate environment for development. On my production server, where we mostly host web applications, we deploy the precompiled version of the web project. While doing development I work on three projects. One is the WCF Service. Two, is the class library project. This library has classes which makes calls on the WCF service. And the third, is a web project which consumes the class library.
The last two projects come under one VS solution. I host the wcf service in the development environment. This service is added as service reference to my class library. I am unable to visualize what will happen once I add the DLL (viz output of the class library project) to my web project, and, the web project has to be deployed. At the time of deployment I have to change the service reference (the url of the svc file will change as it has to point to the production wcf service). How to go about this? What must I take care when adding the dll to the web project?
I am beginner in asp.net / vb.net and I developed a web application for inventory management. here I have my insertion procedure that I entered in my code behind all the different page of my application. My problem is the following:
* I would like to put my procedure in a class that I will call on my different page * how to create this class * how to call this class on my pages
here is my procedure:
Private Sub reqinsertion (ByVal sreq As String)
Dim con As New System.Data.Odbc.OdbcConnection ("Dsn = dshealthboard")
Sun ocommand As System.Data.Odbc.OdbcCommand
con.Open ()
ocommand = New System.Data.Odbc.OdbcCommand (sreq, con)
ocommand.ExecuteNonQuery ()
con.Close ()

actually i was developing 3 tier login page application as following :

WHERE (Name = @Name)
in BLL class in have following :
UserBL.cs

Then i created login.aspx (User Interface )

I've noticed as my website gets bigger and bigger, the time my laptop takes to display my page is much longer then say a new projects with minimal references. I think there are two variables at play that affect ASP.NET warm-up time:
The quantity of external references The time it takes for a worker process to new() up each instance per worker process Additional time for the WCF objects as the ServiceHost may be in an external DLL First, are those the correct variables to take into account when considering ASP.NET startup time? Next, it appears that web.config may dispatch other objects for use with certain filetypes (*.svc, *.aspx, Windows Identity Foundation (WIF), etc. ). This too may cause delays in ASP.NET.
Last, my project is created as a "web project" not a "web site". Not sure if this has an impact. Is my theory full of holes, or is there something I can do to make development on a old laptop any better?
