How can I know which file is add or del by Win32::ChangeNotify/POE::Component::Win32::ChangeNotify?

Hi all monks,
I want to use Win32::ChangeNotify(or POE::Component::Win32::ChangeNotify) to monitor directory, however, how can i retrieve the file name which add/del?

Win32::ChangeNotify does not provide that information. You would have to figure it out yourself by listing the directory before and after the notification and comparing the results. There is another module Win32::AdvNotify which, if you can find the module (update: here is a link), would provide that information, but keep in mind that that module is long unsupported, no source is available, and the author is MIA.

BTW, I could not get POE::Component::Win32::ChangeNotify to work, have you had any better luck? For me, the program exits before it ever calls the notification routine.

Hi runrig,

I downloaded Win32::AdvNofify, but how can i install the module? There is a html file which say install API(http://www.generation.net/~aminer/Perl) before install the module but the link is already unavailable @@ is it talking about win32::API ?

I cannot run POE::Component::Win32::ChangeNotify as well, than I try POE v 0.3301(from CPAN), it can work now, however, the example code exit and print twice of message when it notify

The system call ReadDirectoryChanges provides the info you want. (Win32::ChangeNotify uses FindFirstChangeNotification instead) You could access it using Win32::API, if you so desired.
