Hi,
I'm wanting to have Delphi passively listen for a change in a windows folder
/ directory i.e. when a file suddenly appears in the directory, having been
created by another application, this wakes Delphi up.
I don't want Delphi to be actively polling the directory, but rather
sleeping (while listening on a port), until Windows wakes it up, notifying
it that the directory has changed. This way the Delphi exe, which will sit
on the server, won't be gobbling up CPU when nothing is happening.
What's the term for this and any comments to get me started - e.g. where to
look on the Net?
TIA.
Dave
