Need to execute *.exe in server from ASP.net

Question

My current situation is that I need to execute an exe(which creates a local .txt file) in remote server with IIS hosting an ASP.net/C# API. I created a local user(say userA)

Answer 1

You can use Process.Start

Process process = new Process();
process.StartInfo.FileName = "CVS.exe";
process.StartInfo.Arguments = "if any";
process.Start();

There is also a post about running processes as another user in asp.net:

http://weblogs.asp.net/hernandl/archive/2005/12/02/startprocessasuser.aspx

Supplying user credential

In short it says that you must redirect the process, with code like this:

ProcessStartInfo info = new ProcessStartInfo("cmd.exe");

info.UseShellExecute = false;

info.RedirectStandardInput = true;

info.RedirectStandardError = true;

info.RedirectStandardOutput = true;

info.UserName = dialog.User; // see the link mentioned at the top

info.Password = dialog.Password;

using (Process install = Process.Start(info))

{

      string output = install.StandardOutput.ReadToEnd();

      install.WaitForExit();

      // Do something with you output data

      Console.WriteLine(output);

}

UPDATE: I managed to solve the issue after many weeks. Thank you all for your contribution. Apparently IIS does not load windows user profiles by default. So when running as a different user who is not logged on, their windows profile must be loaded by IIS. In advanced setting menu of your app pool, there is an option "load windows profile" I just changed this to true. In prior versions of IIS, this was set to 'true' by default.
