Hi,
I have a Fileupload control, from where i am uploading CSV file and reading data from it and displaying in a gridview. If data is incorrect i am editting in GrdiView and click on Finish button. On click of finish button i am writing updated value back to CSV file from Gridview. This functionality i have implemented, but after hosting this application in IIS, when i access it in same system its rewriting to CSV file and renaming the file also. But if i browse hosted application in some other system and if i upload a file which is on browser system, its not renaming a file and not updating it.
So please can any one help me what are the permissions i need to set in IIS or to file i am access, so that i can rename and update that file.
I have checked following possiblities already
1. create ASPNET account and grant full permission for read, write....
2. In IIS gave Anonymous access to user.
3. Checked with Impersonate option in web.config file.
4. Gave permissions to CSV file like read, write ....
Code
-----
writing to CSV File
-------------------
StreamWriter sw = new StreamWriter(localsavedFilePath)
foreach (DataRow row in dtCSV.Rows)
{
sw.Write("\"" + row[0].ToString() + "\"");
sw.Write(sw.NewLine);
}sw.Close();
File.Copy(localsavedFilePath, OriginalFileUploadedPath, true);
Renaming File
--------------
File.Move(OriginalFileUploadedPath, OriginalFileRenamedPath);

Check the identity that runs the application pool process. Give that account full control to the directory where you are writing the file.
Also, here is a tip.
Instead of using a StreamWriter, use a StringBuilder to build your .csv then use System.IO.File.WriteAllText.
I didn't get any requirements for the signature

Hi,
Thanks for the reply...
I tried what ever you have suggested, still renaming issue exist. i used string builder to build CSV file and used File.WriteAllText. It works fine only when i run application using Visual Studio and on which ever system i host the application. Except these two systems on all other system its not working.
Please help me.... We need to deliver the project but due to renaming issue stuck up...

What exception are you getting?

I wont get any exception. When i click on Finish button in my screen, i am interacting with DataBase and at last saving the CSV file and changing the name of the file. It wont throw any exception as its working fine in local system using VS2008 application and also when i host the application in my system itself. But if any one browse same application on different system, all Database activities are working fine and even all the code written for renaming CSV file will get executed but it wont rename the file.

In may asp.net application I present a pdf file to the user who enters some data into it and on pressing an HTMLSubmit button on the pdf document posts the data back to an asp.net page where I am able to capture it as formdata using
Request.Form.Item(n) ...
However I have the follwing queries :
1. Can I capture the postback data through the names of the text fields that I have given on my pdf document.
2. Can I capture the post back data in XML format by putting a normal button whose setting are (Control Type:Submit, Submit Format:XML & Submit to URL: the name of the aspx page)?
Kindly help how this can be achieved.
Thanking you in advance

My asp.net application is ajax enabled. After the page is loaded completely, if there is no user activity for sometime, the screen stops responding until i close the browser and open it again.
In some of the screens, on Session timeout (i have tested it by keeping the screens idle for 20 minutes), the user is redirected to the login page.
But on few screens, the redirect does not happen. The screen stands still and no buttons links on the page respond to any mouse or keyboard event.
At this point, if i press the "Refresh" button on the browser address bar, then i get logged out of the application and redirected to the login page.
On the browser Status bar (bottom left hand corner of the browser window) a javascript error message displayed as "Error on Page" instead of "Done".
On click of it, following error messages can be seen in the javascript error message pop-up.
Unexpected ajax response was received from the Server
This may be caused by one of the following reasons:
Server.Transfer
Custom Http handler
Incorrect loading of an "Ajaxified" user control
Verify that you don't get a server side exception or any other undesired behavior, by setting the EnableAJAX property to false.
not possible to add the screen shots, else wd have done.
All the pages and user controls in my application follow the same ajax panel structure and loading.

Sorry to hear that, also your message is cross posted into another forum. That is discouraged here at Code Project.

I will tell you how I have done this in the past.
But a button on your page in design view.
Double click the Button1to get an new method in the code behind. In that method put the code you want to run to update the parent grid...
In the page_load add
Button1.Style.Add("display", "none");
Create a javascript method on the markup
function UpdateGrid() {
var Button1 = document.getElementById("<%=Button1.ClientID %>");
Button1.click();
}
Call UpdateGrid(); in javascript when your window closes or when you need to.
I didn't get any requirements for the signature

Does anyone know how or an article that can tell me how to handle downloading for clients of a website of an odd file.
Say heres the scenario: I want them to pull off a fresh copy of the database as a backup file when they visit a page on my website.
Now i now how to create the bak file , but now I need to know what is the best course of action when downloading it. I can create the file on server and Response.Redirect to the file to case the file to get loaded.
What i would like to know now is there a way this file can be streamed directly to the clients browser without being physically on the server drive.
Or is there a way of creating the file and then deleting once it finished downloading ?
Thanx

Odd file meaning a file that is dynamically generated when requested and is not a functional part (what actually make the website work) of the website. a .bak file which is a sql backup format would be seen as a odd field because it does not get displayed it merely dynamic output provided

Can you please read the rest of the text (and title) it clearly states I know how to create the backup as a file what I would like to know is options to provide this backup file on the fly for my clients.

What was said that that is the current option I am using but would like to know if there are alternatives (please read the whole article)

There is no problem I am looking for an alternative, maybe giving the file to the client on the response stream instead of physically having the file on the server. I know of an example where they actually use a technique to stream a file to limit the amount of kbps each download can use.
And please refrain from marking your post as an answer when u are just asking questions

Yes! you can add connection string at Global.asax.
code of global.asax with Connection String:
---------------------------------------------------------------------------
]]>
]]>
void Application_Start()
{
//Connection string for SQL Server with trusted connection
Application.Add ("DB_CONNECTION_STRING","DRIVER={SQL Server};SERVER=ServerName;DATABASE=DataBaseName;Trusted_connection=yes;");
}
void Session_Start()
{
//open connection to database
OdbcConnection cnConnection = new OdbcConnection (Application.Get("DB_CONNECTION_STRING").ToString());
cnConnection.Open();
Session.Add ("DB_CONNECTION", cnConnection );
}
void Session_End()
{
//a graceful disconnect
OdbcConnection cnConnection = (OdbcConnection) Session["DB_CONNECTION"];
cnConnection.Close ();
}
