You can watch for changes in files and subdirectories of the specified directory. Use FileSystemWatcher to watch for changes in a specified directory. If (e->ChangeType != WatcherChangeTypes::Changed)Ĭonsole::WriteLine("Changed: ") Static void OnChanged(Object^ sender, FileSystemEventArgs^ e)
Watcher->Error += gcnew ErrorEventHandler(M圜lassCPP::OnError) Ĭonsole::WriteLine("Press enter to exit.") Watcher->Renamed += gcnew RenamedEventHandler(M圜lassCPP::OnRenamed) Watcher->Deleted += gcnew FileSystemEventHandler(M圜lassCPP::OnDeleted) Watcher->Created += gcnew FileSystemEventHandler(M圜lassCPP::OnCreated) Watcher->Changed += gcnew FileSystemEventHandler(M圜lassCPP::OnChanged) Watcher->NotifyFilter = static_cast(NotifyFilters::Attributes #include "pch.h"įileSystemWatcher^ watcher = gcnew FileSystemWatcher("C:\\path\\to\\folder") When a file is renamed, the old and new paths print to the console. If a file is changed, created, or deleted, the path to the file prints to the console.
