How do I start a local application from within a web form?

[Phillip N Rounds]

What I would like to do is to have a console application on my server
started when a user performs a specific action on a web form. Specifically,
MyConsoleApp overwrites an existing file with updated info.
MyConsoleApp.exe works just fine and I believe the codewhich calls the
MyConsoleApp.exe (below) is correct. This process fails, with an error:
Access is denied
User Account MyComputer\ASPNET

This makes sense, my computer shouldn't permit an unknown user to write to
my disk. Do I have to create a user account ASPNET and give write
permission in the appropriate directory to this user?
Is trying to do this such a horrendous idea that I should find a different
approach?


Thanks

Phil

I have the following in an appropriate place in my web form:
System.Diagnostics.ProcessStartInfo ProcInfo = new
ProcessStartInfo("c:\\MyConsoleApp.exe", null );

ProcInfo.UseShellExecute = true;

System.Diagnostics.Process Proc = new Process();

Proc.StartInfo = ProcInfo;

Proc.Start();

add the ASPNET user to the permissions of the folder. Give it read and
write and you should be good to go

By the way, the username ASPNET already exists by default, the user
that is used can be set in the machine.config

IIRC, you need to run the process with an account
that has permission to access the directory's or file objects.

Look into running MyConsoleApp as ( using runas ) the ASPNET account
(if you gave the necessary permissions to the ASPNET account)
or as any account you want to, as long as it has R/W/M permissions
to the directories/files you need to access/modify.

See :

Probably something like this :
System.Diagnostics.ProcessStartInfo ProcInfo = new ProcessStartInfo("runas /user:MyComputer\account
c:\\MyConsoleApp.exe", null );
