I have created a web app with 4 layers : Presentation - Business - Services - Data. I have Business.Entities project which is added to Business layer and have Employee class in it.
I also have DataAccess.Entities and Presentation.Entities and have added Employee.cs in there also. Now in project references I have added Presentation project reference in Business, Business project reference in DataAccess.
Is this approach correct?
My Question is, Should Employee.cs class be added to each project entities like I did above or should Employee.cs be added to only Business.Entities project and Business.Entities proj reference be added to all projects?
I got this question because the 2nd approach was used in a project I downloaded from internet.
Please help.

You should follow one basic principle : Do not write redundant code. i.e. If you add Employee.cs to all the projects it would simply be the copy paste. Any change in this class will force you to change it in all the projects.
My recommendation :
As you have mentioned, you have Business.Entity project, add all the entities including Employee.cs in this project only. And then this project be added as a reference to rest of the projects.
Hope this helps.
All the best.

Thanks Pravin. You pointed out not to write redundant code and that is excellent.
But I have a question here. When following layers, do we not have to add the reference of Business in DAL, Presentation in Business etc. so that the flow will be maintained.
If Business project is added as reference on all projects, would the layered architecture model not be affected?

I highly appreciate your response. You raised a very correct and genuine concern. You have two options.
Options 1:
Keep the business entity and business logic altogether different. In business entity you will have only public properties exposed. in simple terms it will act as a container for the data that flows through the layers. And business logic will have the core busines logic in it. Now, in this approach you only need to add the reference of Business entity in all the layers. Presentation, Business and DAL.
Options 2:
You will have no difference between Business logic and Entity. You can merge these two layers. i.e. Public properties and the business logic pertaining to that will be in the same class. Validation also goes in the same class. In this case you will have to add reference of this layer to both presentation and Data layer.
Both these approaches are used extensively in the Software Industry. However, second approach is much more extensively used, even it is used in MVC, MVP and MVVP architecture.
Hope this helps.
All the best.

I guess you can create it on your users table.
I Love T-SQL

To create a user you can make a registration form for filling userid and password choosing by the user.
These values should be inserted in databse and can be used for further login.

I am working with a C#.net web forms 2010 application that I am going to be adding some web forms to the entire application. I am asking the following question since I have C#.net expereince working with desktop applications.
When debugging a desktop application, I can 'step into the code' for a designer. (This may be allowed since the code generated by the designer is C# code.)
Thus, I would like to know if I can 'step into' the code generated by the asp.net designer. This code ends up being html. If this is possible, can you tell me how to step into this html that the desginer setup and/or point me to reference on how to debug the html (designer code)?
Also can you debug xml (like the web config file)? If so,would you point me to a reference i can use for debugging xml?

Hi
When clicking the log out button on my ASP web application, the following is executed
Session.Abandon
but when i click the back button on the ie browser, i'm being redirected to the previous page though the session has expired.
I've tried using the no cache code
Response.Buffer = True
Response.ExpiresAbsolute = Now() - 1
Response.Expires = 0
Response.CacheControl = "no-cache"
This has worked as after logout when I clicked on the ie browser back button i'm being redirected to the login page
But when the session hasn't expired and the user is using the application and at some point when he clicks the ie browser back button, he is getting the ie error message "Page cannot be displayed". I think this being caused by the no cache code
Is there any way to avoid this?
Cheers

I think this is because of the expiry that you have set for the response.
Could you please try remove the expiration and only use,
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Buffer = True;
This is not a tested code. If you try this way then it should work. I assume that you have proper session validation logic in your pages.

Oh, I thought it was for ASP.NET.
Could you please try the same logic in ASP (remove the expiration)?
You'll find some equivalent snippets in ASP.

I did but it didn't work out.
Was thinking if there is a way to refresh the page when the back button on the ie browser if triggered

hello very one 
i need some help or advice from the people , who have expert in asp.net
this is my problem
the url for example is
http://localhost:2940/website/page.aspx?ID=1
when i change id to
http://localhost:2940/website/page.aspx?ID=100000000000000000000000000000000000
i get error manege
The conversion of the nvarchar value '20000000000000000000000000000000' overflowed an int column.
i need if the ID dose not exist in database table , redirect the page to homepage
thx all

I believe you are converting this value into int type and it's exceeding the max size. So use Long type.

there is 2 way to handle this issue
1) increase the size of Column of id in database
2) before executing query for existing of id check length of ID
if it is less then the column size then go ahead. else return false from there no need to execute query.
I prefer to use 2nd method.
Remember one thing that when you execute sql query always check length of fields which you are using in query.
Thanks
As our case is new, we must think and act a new.

In the Page_Load event...
[put code to check if ID is valid here, then. . .]
If (NotValid)
{
Server.Transfer("Default.aspx");
}
else
{
DoAllTheNormalStuff();
}

thank u all

thank all again

Try this but the code is in vb,get the idea and convert to C#(if you use C#)
Private Function CheckID(ByVal strID As String)
Dim strSQL As String
Dim conn As New OracleConnection
Dim reader As System.Data.OracleClient.OracleDataReader
strSQL = "Select ID From <Your table's name> Where ID = '" & strID & "'"
Dim cmd = New OracleCommand(strSQL , conn)
reader = cmd.ExecuteReader()
If reader.Read() Then
If reader.HasRows Then
Return True
Else
Return False
End If
Return ""
End IF
In your page load or load complete,call CheckID() and insert ID into it.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If CheckID("<your ID here>") = True Then
Response.Redirect("newpage.aspx")
Else
Response.Write("<a href=""page.aspx"">Error. There is no page ID in our database</a>"
End If
