  1. POFIleSystemWatcher last access (read) for media files is not working
    text
    copied!<p>I am delivering media contents to a client system (download from internet) and want to acknowledge if the media file was opened (and viewed) by the operator. I am using a file system watcher (C# 3.5) to check for the last access time of file (so whenever the media file is played I should get the event) and I send an acknowledgement. </p> <p>I have enabled the last access time in registry of my Windows 7 machine <a href="http://www.febooti.com/products/filetweak/online-help/file-last-accessed-date.html" rel="nofollow">here</a> and rebooted my system. File system watcher fires events on directory opened but not on media play. </p> <p>Here is my code : </p> <pre class="lang-cs prettyprint-override"><code>private FileSystemWatcher fsWatcher = null; private static Object objLock = new Object(); private void StartAccessWatcher(string _folderPath) { fsWatcher = new FileSystemWatcher(_folderPath, "*.*"); fsWatcher.Changed += new FileSystemEventHandler(fsWatcher_Changed); fsWatcher.IncludeSubdirectories = true; fsWatcher.NotifyFilter = NotifyFilters.LastAccess; fsWatcher.EnableRaisingEvents = true; } private void fsWatcher_Changed(object sender, FileSystemEventArgs e) { lock (objLock) { fsWatcher.EnableRaisingEvents = false; DisplayMessage(string.Concat(e.ChangeType, " ", e.FullPath)); fsWatcher.EnableRaisingEvents = true; } } private void btn_StartWatcher_Click(object sender, EventArgs e) { StartAccessWatcher(@"E:\Surewaves\Media-Store\MP1 Videos"); } </code></pre> <p>You may also download my code sample from <a href="http://www.4shared.com/zip/Pj7useWZ/WatchFileAccess.html" rel="nofollow">here</a>.</p> <p>Please tell me how best can I achieve it ? I need to get the the last access time (when ever the video or audio or image or .swf file was played by any player) ?</p>
