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.

thanks for the reply but the code you've mentioned is for ASP.Net not ASP.
I need for ASP

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();
}

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

I am new to C#.net web applications but I have worked on C#.net desktop applications.
I am trying to determine what is the startup point is for a C#.net 2010 web application. In a desktop application, you can find a program.cs file that contains a static main method. H
However in the C#.net web application I am looking at, there is no program.cs file. Thus how can I tell what the startup file is? At least what is the main method I am looking for? If there are several main methods, which one am I looking for?

There is no "main" method as such in a web application. What you have, instead, is a set of web pages each of which have a well defined set of core events and overrides that you can hook into. In general, most pages (assuming this is a classic ASP.NET application) will contain a Page_Load event, which is a fair place to start debugging. What you may want to do is have a look at the Request/Response lifecycle for ASP.NET applications to see where the different events are handled.
I suggest that you need to buy a book on ASP.NET, as it is so different to developing desktop applications that you need to get your head around the differences.

The entry point in an ASP.NET application is typically Default.aspx, though this can be configured in IIS (Internet Information Services, the standard web server to use with ASP.NET).

Hi,
I have a scenario like this.
I have two asynchronous service calls AsynchronousCal1 and AsynchronousCal2. And two response handlers ResponseHandler1 and ResponseHandler2. When AsynchronousCal1 finished ResponseHandler1 will be called. When AsynchronousCal2 finished ResponseHandler2 will be called.
Now I want to call a method "RunMethod" when the above two Response handlers completed.
The above two calls are asynchronous and I am calling them paralelly (Its mandatory for me to call them paralally), we are not sure which ResponseHandler will complete first and which ResponseHandler will complete second.
How to handle this situation in ASP.NET and C#?
Thanks in Advance.

Yes you can.
You need to do a little process which is that you need to import market price dailybasis.
Where you can get Daily Market Price?
For this you need to open site for NSE or BSE and there is a link for download daily market price after market close.
www.bseindia.com/mktlive/bhavcopy.asp[^]
www.nseindia.com/archives/archives.htm[^]
you can easily import these files to your database.
