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.

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.

Hi,
We are trying to connect to DB2 from .Net via IBM DB2 Data provider. We are not able to establish the connection using the CFWEBUSER profile created.
We are checking for other options to establish the connection.
Tried checking the CFWEBUSER Profile directly in DB2 box. We have limitations in using the queries using the CFWEBUSER As400 profile. We have “Start Structured Query Language (STRSQL)” command in AS400 which starts the interactive SQL program to write the SQL queries. I’m not able to access this command using the profile mentioned.
Any Db2 guys here,,,,,,,,,what is CFWEBUSER profile.
Thanks

Hi i m using paypal IPN for payment notifications. I am using the same code provided by Paypal however i m having issues. Here is the code
string strSandbox = "https://www.sandbox.paypal.com/cgi-bin/webscr";
string strLive = "https://www.paypal.com/cgi-bin/webscr";
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(strSandbox);
//Set values for the request back
req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";
byte[] param = Request.BinaryRead(HttpContext.Current.Request.ContentLength);
string strRequest = Encoding.ASCII.GetString(param);
Dictionary<string, string=""> nvs = new Dictionary<string, string="">();
string[] items = strRequest.Split("&".ToCharArray());
foreach (string item in items)
{
string[] parts = item.Split("=".ToCharArray());
nvs.Add(parts[0], HttpUtility.UrlDecode(parts[1]));
}
strRequest += "&cmd=_notify-validate";
req.ContentLength = strRequest.Length;
//for proxy
//Hook up 1&1 proxy server
//WebProxy proxy = new WebProxy("ntproxyus.lxa.perfora.net:3128",false);
//req.Proxy = proxy;
//Send transaction detail with the flag back to PayPal
StreamWriter streamOut = new StreamWriter(req.GetRequestStream(), System.Text.Encoding.ASCII);
streamOut.Write(strRequest);
streamOut.Close();
//DataLayer dl3 = new DataLayer();
//dl3.executeQuery("Update petOwner set orderStatus = 'Afterproxy(Invalid Card)' where orderId = '" + Request.Form["item_name"] + "'");
//Get validation status from PayPal
StreamReader streamIn = new StreamReader(req.GetResponse().GetResponseStream());
string strResponse = streamIn.ReadToEnd();
streamIn.Close();
//DataLayer dl4 = new DataLayer();
//dl4.executeQuery("Update petOwner set orderStatus = 'Afterproxy2(Invalid Card)' where orderId = '" + Request.Form["item_name"] + "'");
if (strResponse == "VERIFIED")
{
//check the payment_status is Completed
if (nvs["payment_status"] == "Completed")
{
//check that txn_id has not been previously processed
//check that receiver_email is your Primary PayPal email
//check that payment_amount/payment_currency are correct
//process payment
DataLayer dl = new DataLayer();
dl.executeQuery("Update petOwner set orderStatus = 'Paid' where orderId = '" + Request.Form["item_name"] + "'");
CheckPaymentMode();
SendOrderEmail();
}
}
else if (strResponse == "INVALID")
{
DataLayer dl = new DataLayer();
dl.executeQuery("Update petOwner set orderStatus = 'Not Paid(Invalid Card)' where orderId = '" + Request.Form["item_name"] + "'");
//log for manual investigation
}
else
{
DataLayer dl = new DataLayer();
dl.executeQuery("Update petOwner set orderStatus = 'Not Paid(Invalid Card)' where orderId = '" + Request.Form["item_name"] + "'");
//log response/ipn data for manual investigation
}
}
The code is working fine untl this line of code
StreamWriter streamOut = new StreamWriter(req.GetRequestStream(), System.Text.Encoding.ASCII);
streamOut.Write(strRequest);
streamOut.Close();
When it comes to send request to paypal. from here on no line of code gets executed.
I ve contacted the hosting company they are saying no proxy is needed to send request.
I am unable to trace the issue. Need urgent help
Thanks in Advance,
Asfand

Please put your code in <pre> tags so that it's readable. (Use the "code" formatting.)
The difficult we do right away...
...the impossible takes slightly longer.
