Stopping a user from accessing a folder

[cameron2]

Hi
I'm making a security application and want to know how to check if a folder is open and how to close that folder (maybe by killing explorer) if i dont want it to be accessed. Would i use systemfilewatcher?

Thanks
Cameron.

The simple fact is that you wouldn't. Windows has in-built security to prevent users accessing folders and that's what you should be using. A high-level language like VB is simply not appropriate for low-level security.

Yes i understand what your saying it's just i would like to know if there is a way you could do it.

By the way what is this windows built in security to stop users accessing a folder?

That's beyond the scope of a forum dedicated to VB.NET programming but in brief you can set file and folder permissions on a per-user basis. How do you think large companies implement security? If you want security then you should use what the OS provides first, then look elsewhere if it's inadequate in some way.

I realise you can set folder permissions with windows but i want my application TO DO this and am wondering if anyone knows hoe.
