· I have added aspnet account to administrator group.

· I have added NETWORK SERVICES, ASPNET and IUSR_systemname to the sucurities tab of the folder

Hi Krishnaveni,

Here is a thread about how to run a process by using specific user account, Perhaps you will get some helpful information.

I think the best approach here is to use class File, FileInfo, DirectoryInfo, TextReader and StreamReaderfrom System.IO especially that you are working on web application.

//Find Directory of the file

DirectoryInfo dir = new DirectoryInfo(Server.MapPath("") + @"\YourFolder");

//Iterate the file from directory
foreach (FileInfo file in dir.GetFiles(String.Format("*_{0}.txt", User.Identity.Name)))
{

//Open and read the file
TextReader text = StreamReader(file.FullName);

Console.WriteLine(text.ReadLine());
}

You are using the test web server that comes with Visual Studio -- not IIS. This test server is actually a standalone, Windows GUI application running under your user. Therefore, you are able to display notepad (or another editor) successfully in testing.

As the previous poster has indicated, the IIS service / worker process is not designed to display a GUI.
