I need to detect changes to (certain) files whenever they are accessed, a bit similar to what a virus scanner does with on-access scan.
Also, I need to get notified whenever a change of any kind is made in the registry.
Rather than taking snapshots of the file(s) or registry and then compare them to what I had earlier, I was hoping to be able to get some sort of event that I could subscribe to. Is that possible?

A good start, I suppose, but I'd hoped for something that would send an event to me when it happened. I suppose that I will have to poll the directory I watch (which by choosing C:\ I suppose will give me all changes on that drive for instance). Hm...but it did say something about an asynchronous operation...I wonder if I could call it and order it to return whenever something happened. Then I would sort of have an event sent to me...
It does. Use the async implementation. The callback function will be triggered if something happened. Google a bit for 'filewatcher c++'... there are a lot of ready to use classes out there.Quote:

Cool, thanks.
I hope there's something similar for the registry...
RegNotifyChangeKeyValue should provide registry notification.
It seems we're on the right track here. :-)
However, while RegNotifyChangeKeyValue() will tell that something has changed, it seems that in order to get to know *what* was changed, one needs either Vista or Server 2008. Since there are still lots of XP clients out there, I hope there is also something to get details of the change that will support XP.
