Then one of them is not processing the page any more, just running in the background. Once you end the response, it doesn't matter if you have a thread running in the background. This of course means that the background thread can't send anything to the browser any more, as the response has ended.

Is that the page containing the upload form, or the page that is recieving the file? Or are they the same? The page recieving the file has to be sessionless, as that's the one running while the file is uploading.
I have myself written an upload application that used a sessionless page for displaying upload progress, so I know that it's possible to do it this way.
lokeshgupta13 wrote: Is there any other way to achieve the same without disabling the SessionState?
Not unless you can get rid of the single page limitation in the IIS, but I really doubt that is possible. That could introduce threading issues, as you will have several threads running against the same session object. Also it would make the server much more sensetive to DoS attacks.

In my case both the "Upload Form" and "Receiving form" are the same. I am using same form. I am not getting what is going wrong.
Thanks

Have you verified that trying to access the Session object in the page gives an excception, so that you are sure that the page is session-less?

i am using vs2003
i want to write some text into an existing file present at server side using asp.net but it gives me an exception named
----->System.UnauthorizedAccessException: <------
so i need how to get permission to write file to server
any suggestions are also welcome
the code i used is given below---
Dim fs As New FileStream("C:\Inetpub\wwwroot\wa_readfromcsv\textfile_as_csv.txt", FileMode.Create, FileAccess.Write)
Dim s As New StreamWriter(fs)
s.WriteLine("This is an example of using file handling concepts in VB.NET.")
s.WriteLine("This concept is interesting.")
s.Close()
------- the exact error shown is ---------
' Exception Details: System.UnauthorizedAccessException:
' Access to the path "C:\Inetpub\wwwroot\wa_readfromcsv\textfile_as_csv.txt" is denied.
'ASP.NET is not authorized to access the requested resource.
'Consider granting access rights to the resource to the ASP.NET request identity.
'ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5
'or Network Service on IIS 6) that is used if the application is
'not impersonating. If the application is impersonating via <identity impersonate="true">,
'the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.
'To grant ASP.NET write access to a file, right-click the file in Explorer,
'choose "Properties" and select the Security tab.
'Click "Add" to add the appropriate user or group.
' Highlight the ASP.NET account, and check the boxes for the desired access.
thanks in advance for your help and time...

The error message tells you what you need to do. Basically, the ASPNET user does not have write permissions for this directory. You need to grant this user permissions to the directory. Follow the instructions in the error for granting ASPNET access.

thanks for your reply ..
about the suggested solutions
for first suggested way--- i dont know how to grant permission to the user .
for second way--- i dont think that changing in my system will solve the problem globally because application is web application .does the second solution mean that i need to change in explorer of system where i installed the application ...i dont think so ..even thought i do it is something like i will only use the application at client side it appears...
...so please explain me clearly what the error message says me to do.

OK - as you are running this as a web application, then fixing it at the server is enough. Right-click on the directory that you are trying to write this file to, choose Properties and select the Security tab. Click the Add button and choose the ASPNET (if you are running IIS5) or Network Service (if you are running IIS6) user. This user is a local account. Select OK and then choose the relevant permissions at the bottom of the properties dialog. Once you have chosen the permissions to grant, click OK.

that was a very clear description thank you very much
but its still not working ....
what does this mean in the error description something with "impersonating"..
" that is used if the application is
'not impersonating. If the application is impersonating via ,
'the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user"
i dint get exactly which user to modify ...just assume that i am using a simple webiste and its accessible to all ..so no authentication.
but may be the code has any issue please check the 5 line code also
assume file is already present.
thanks for your effort..

T-SQL transaction vs ADO.NET transactions
What is the better to use between them?
waiting for prompt reply

Please don't put things like this into a question. The people on this site give their help freely, and in their own time. If somebody can answer you, they will.
Anyway, you would use a T-SQL transaction when you can accomplish everything inside the same top level stored procedure. ADO.NET transactions allow you to wrap multiple stored procedures into the same logical transaction.

hi all,
I want to publish my web site and i dont want users to be able to see my connection string in web.config. How can i do that in an easy & simple way. Any encryption code or another way?
Thanks
SH

The code you need to encrypt/decrypt your connection strings section in your web.config file looks like this:
public void EncryptConfigSection(bool bEncrypt)
{
string pathToConfigFile = "~/";
Configuration config = WebConfigurationManager.OpenWebConfiguration(pathToConfigFile);
ConfigurationSection connStrings = config.GetSection("connectionStrings");
if (true == bEncrypt)
connStrings.SectionInformation.ProtectSection("DataProtectionConfigurationProvider");
else
connStrings.SectionInformation.UnprotectSection();
config.Save();
}

hi
i want to validate a Textbox which is in a webpartZone, i am able to do that when my aspx page is not inheriting from master page, but when I am using a aspx page with master page and my Textbox in side a webpartZone I am not able to valdate the text box .it through an error Unable to find control id 'TextBox1' referenced by the 'ControlToValidate' property of 'RequiredFieldValidator1' please give some .

Hello.
Do you have another "TextBox1" somewhere on your page? Perhaps in the Master page itself? If so - ASP.NET renames the controls in order to get a unique ID. It should automatically rename your RequiredFieldValidator1 reference to the control as well. But perhaps this does not happen as expected. Anyway you should go check it out. I've found the best way to debug this, is to try and rename your control to something logic eg. "txtName" - that way you ensure, that you decide the names, and not Visual Studio, because, well, it's best the other way around. 
Best Regards

Dear All
I want to creat a regular expression for a dropdown list
My first item in the dropdown list is "Please Select One..."
So i want to create a regular expression to validate this
i mean, i don't want to keep the dropdownlist with it's default selected value, i want to force the user to select one item
And if there is a better solution for that, please tell me about it 
Thanx in advance
Best Regards

Why don't you put a tabcontrol on a single form, and navigate between the tabs if required. You can hide the tabs so the user won't see that you're using a tabcontrol...
