Beispiel FileSystemWatcher

Zickedi

Gibts irgendwo ein Beispiel für Managed C++, das den Watcher beinhaltet? Einfaches Konsolenprogramm genügt...

Jochen Kalmbach

Nimm doch das beispiel aus C++/CLI:
http://msdn2.microsoft.com/en-us/library/system.io.filesystemwatcher.aspx
und ersetze ^ durch * und gcnew durch new...

Danke, funktioniert. An die msdn2 hatte ich nicht gedacht.
Mein Code sieht so aus:

#using <mscorlib.dll>

using namespace System;
using namespace System::IO;

public __gc class Watcher {

private:
   // Define the event handlers.
   static void OnChanged( Object* /*source*/, FileSystemEventArgs* e ) {

     // Specify what is done when a file is changed, created, or deleted.
     Console::WriteLine("File: {0} {1}", e->FullPath, __box(e->ChangeType));
   }

   static void OnRenamed( Object* /*source*/, RenamedEventArgs* e ) {

     // Specify what is done when a file is renamed.
     Console::WriteLine( "File: {0} renamed to {1}", e->OldFullPath, e->FullPath );
   }

public:
   void run() {

     // Create a new FileSystemWatcher and set its properties.
     FileSystemWatcher* watcher = new FileSystemWatcher;
     watcher->Path = AppDomain::CurrentDomain->BaseDirectory;

     /* Watch for changes in LastAccess and LastWrite times, and 
         the renaming of files or directories. */
     watcher->NotifyFilter = static_cast<NotifyFilters>(NotifyFilters::LastAccess |
            NotifyFilters::LastWrite | NotifyFilters::FileName | NotifyFilters::DirectoryName);

     // Only watch text files.
     watcher->Filter = "*.txt";

     // Add event handlers.
     // hier wurde this-Zeiger eingefügt
     watcher->Changed += new FileSystemEventHandler(this, Watcher::OnChanged );
     watcher->Created += new FileSystemEventHandler(this, Watcher::OnChanged );
     watcher->Deleted += new FileSystemEventHandler(this, Watcher::OnChanged );
     watcher->Renamed += new RenamedEventHandler(this, Watcher::OnRenamed );

     // Begin watching.
     watcher->EnableRaisingEvents = true;

     // Wait for the user to quit the program.
     Console::WriteLine( "Press \'q\' to quit the sample." );
     while ( Console::Read() != 'q' )
       ;
   }
};

int _tmain() {

  // Watcher::run(); // von msdn2
  Watcher* w = new Watcher();
  w->run();

  return 0;
}

Noch eine Frage:

(edit) geklärt...
