If I was doing a directory watcher I would create a thread that would use
FindFirstChangeNotification, this function returns a handle that you can
wait on (WaitForSingleObject, WaitForMultipleObjects), when something
changes your wait with get signaled.
There are also a bunch more stuff you can monitor, see the help for
FindFirstChangeNotification.

Hello friends,

I have created a directory watcher in vc++, using
ReadDirectoryChangesW API.
It can watch any changes within the directory.

But it can't detect the directory deletion event, because
ReadDirectoryChangesW method doen not have this capability i think.

Is there any way so that my application can recognize the directory
deletion events.

Example:

Suppose my application is watching directory "C:\Harry\A". Right now
my application has the ability to detect all chnages made inside the
directory 'A'. But suppose i deleted the directory using DELETE
button, then it does not detect this notification.

Can anyone help me please.
