monitoring a file for changes (createchangenotify?)

[Wayne Diamond]

Does anybody have any examples of monitoring a single file for changes? From memory theres an API call called SomethingChangeNotify or thereabouts, Im sure somebody here has done it before but I couldnt find any links?

The APIs you are after are
FindFirstChangeNotification and FindNextChangeNotification.
Also, if you need a responsive GUI you will need
MsgWaitForMultipleObjects.

There is a nice example of this in Advanced Windows by Jeffrey Richter
in the chapter on file systems(FILECHNG.EXE).
The new version of his book has a new name. I don't remember what it
is at the moment.

Also, in the source code forum I posted an 'Internet Cookie Monitor" program which uses the File Notify stuff. It includes the code you need to figure out which file in a folder has changed.

This was 4-6 weeks ago if you use the search. (Just search on "cookie" it should turn up).
