    <p>You can setup monitoring the file by using the <a href="http://msdn.microsoft.com/en-us/library/system.io.filesystemwatcher.aspx" rel="nofollow">System.IO.FileSystemWatcher</a> you should be able to use that the <a href="http://msdn.microsoft.com/en-us/library/system.io.notifyfilters.aspx" rel="nofollow">NotifyFilter</a> property (set to LastAccessTime) to detect when a particular file was last accessed. </p> <pre><code>void SetupWatcher() { // Create a new FileSystemWatcher and set its properties. FileSystemWatcher watcher = new FileSystemWatcher(); watcher.Path = @"C:\"; /* Watch for changes in LastAccess and LastWrite times, and the renaming of files or directories. */ watcher.NotifyFilter = NotifyFilters.LastAccess; // Only watch text files. watcher.Filter = "*.txt"; // Add event handlers. watcher.Changed += new FileSystemEventHandler(OnChanged); watcher.Created += new FileSystemEventHandler(OnChanged); watcher.Deleted += new FileSystemEventHandler(OnChanged); watcher.Renamed += new RenamedEventHandler(OnRenamed); // Begin watching. watcher.EnableRaisingEvents = true; } // Define the event handlers. private static void OnChanged(object source, FileSystemEventArgs e) { // Specify what is done when a file is changed, created, or deleted. Console.WriteLine("File: " + e.FullPath + " " + e.ChangeType); } private 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); } </code></pre> <p>Another option assuming this is windows is to enumerate the list of open file handles for each process. The code posted <a href="http://vmccontroller.codeplex.com/SourceControl/changeset/view/47386#195318" rel="nofollow">here</a> has a decent implementation so all you have to do is call </p> <pre><code>DetectOpenFiles.GetOpenFilesEnumerator(processID); </code></pre> <p>However, if a process opens a file reads the contents into memory then closes the file, you will be stuck with the monitoring option (listed above), since the process does not actually have the file open any longer once it is read into memory.</p>

    1. COI can't use FileSystemWatcher. See comment below question.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
