after that. he log-off windows(xp) and then when my program is attempting to run on startup MyApp.exe , i wont because it got renamed

is it possible to prevent this through codes?

thanks to anyone who would help =)

You can't really attempt to stop this. It's the user's computer and if they want to rename files on their computer they can do.

That is not possible.

However there is an alternative to do that. You can set the user to have limited rights on his user account to the computer. In that case he cannot rename files in such a way he wanted. This is a restriction provided by the operating system in which only the administrators of the computer can set these restrictions to user accounts.

EDIT What I mean here is if you are the administrator of the computer, as an alternative you can manually limit the privileges of the users who logs-in to the computer. For a better understanding on what I mean, please read the replies on my post. :)

You can place your application somewhere the user is less likely to go and rename it, like in the program files folder. But you can't stop them actually renaming the application.

If the user isn't an administrator on that machine they won't have permissions to rename files in the Program Files directory by default. One would hope that unfriendly users aren't administrators on the target machine (If they are, they can do a lot worse than renaming one application file).

You can check what name the executable has when it's being run.

But you cannot prevent a user from renaming it.

You might consider using clickonce publishing. For the life of me I can never guarantee I can find the ruddy application after installing it with clickonce so that might stop your friendly user messing with the app? ;-)

Here is some info on ClickOnce Publishing.

In essence, write an application, right click the project/solution, choose "Publish", then follow the wizard.

It won't guarantee the user won't be able to rename and mess with the files, but it'll make it harder.

1. By permissions way as most folks here explained.
2. Stupid and waste method is to have a daemon (Service) running accessing this file all time since system boot. That way system wont allow this executable to be renamed unless this daemon is stopped.

you can prevent renaming or moving your exe file while it is running. Open the exe file within your exe file for reading and deny writing. Keep this file open as long as it runs.
