There are times when a directory needs watched. For reasons of its own, a program may need to know when a file is deleted, updated or renamed. If .NET is involved, this is a trivial task. Create an instance of the FileSystemWatcher; set some properties, and the task is completed. If a non .NET solution is required (and regardless of the hype, some people haven't embraced .NET in all of its glory.), the ReadDirectoryChangesW function must be used, however the documentation for ReadDirectoryChangesW is sketchy at best.

I'd kinda like to see FAM supported in kernel on all platforms, especially for those that use gconf as it seems to make the biggest impact there on my OBSD system (no FAM) compared to my Gentoo system (FAM). Gnome-VFS (can) use(s) FAM, and frankly I like it from an app devellopment point of view.

KDE already does this, so I assume it should be fairly straightforward to do with Qt on Windows since there's now code available online...

I use Delphi all the time and really enjoy thoughtful articles like this. thanks.

There are hell of a lot of things .NET isn't good for and this is one of them.
Who in their right mind is going to let some crap running under .NET delete, update or rename any fricking files without their permission if they can help it?
And if they are going to give their permission why bother
running a .NET app to begin with?

I think that you should understand what you are reading before you post a comment. The article is about monitoring file system actions, not performing them.
Rick James is an idiot who does not have the intelligence to latch on to the fact that directory and file change monitoring is pretty much a standard mode of operation for many apps and background processes.
"If a non .NET solution is required the ReadDirectoryChangesW function must be used"
That statement is false.
There are other Win 32 API calls that can accomplish the same thing (FindFirstChangeNotification).
Francois Piette wrote a Delphi component 7 years ago that accomplishes the same thing.
If I knew I could get fairly random Delphi articles published on OSNews I would have written a few by now... LOL! Not clear how this is OS related as it is a pretty simple example and Windows centric... ah well.
Click on the gear-looking icon near the top of this article. That is the topic "development" topic. OSNews frequently posts news about this. You must be new here.
No.. I'm just a Delphi developer. This article is worrying me because this sort of stuff is Win32 101. This is "bread and butter" coding for me. It's not what I would class as something worthy of publishing here.
But, hey, who am I to complain about a Delphi article!!
This does much the same (though in C++... not exactly hard to convert to Delphi though):

Yes, so???
Windows is an OS, right?
