[AccessD] Cool stuff - was RE: using a dtsx in .Net

Hi Stuart

Yes, that was the case.
By second thought, it wouldn't take that much to load the list of files of the directory under observation into an array or collection at launch, then when "something happens" reread that list and pull out the new entries.

That will happen especially if you are monitoring  the 
FILE_NOTIFY_CHANGE_SIZE or the FILE_NOTIFY_CHANGE_LAST_WRITE  events. 
(Probably  the more common ones in practice)

 The operating system detects a change in file size only when the file is 
written to the disk. For operating systems that use extensive caching, 
detection occurs only when the cache is sufficiently flushed.
