Trigger on changes in Directory

[willyfoo]

Anybody knows how to achieve minimal system resources to detect for any changes made to a directory/folder (eg. New file, changed file) to trigger running a function?

I've tried polling every 0.x seconds but don't feel it's the most efficient.

The closest lead I have is http://www.thescarms.com/vbasic/FolderSpy.asp

It uses FileSystemObject of scrrun.dll

Worst case scenario is to run the above program and do an adlib on it to detect for it's aleart but how to access the FileSystemObject directly to achive the same effect?
