    <p>You could use the following:</p> <pre><code> private ManagementEventWatcher WatchForProcessStart(string processName) { string queryString = "SELECT TargetInstance" + " FROM __InstanceCreationEvent " + "WITHIN 10 " + " WHERE TargetInstance ISA 'Win32_Process' " + " AND TargetInstance.Name = '" + processName + "'"; // The dot in the scope means use the current machine string scope = @"\\.\root\CIMV2"; // Create a watcher and listen for events ManagementEventWatcher watcher = new ManagementEventWatcher(scope, queryString); watcher.EventArrived += ProcessStarted; watcher.Start(); return watcher; } private ManagementEventWatcher WatchForProcessEnd(string processName) { string queryString = "SELECT TargetInstance" + " FROM __InstanceDeletionEvent " + "WITHIN 10 " + " WHERE TargetInstance ISA 'Win32_Process' " + " AND TargetInstance.Name = '" + processName + "'"; // The dot in the scope means use the current machine string scope = @"\\.\root\CIMV2"; // Create a watcher and listen for events ManagementEventWatcher watcher = new ManagementEventWatcher(scope, queryString); watcher.EventArrived += ProcessEnded; watcher.Start(); return watcher; } private void ProcessEnded(object sender, EventArrivedEventArgs e) { ManagementBaseObject targetInstance = (ManagementBaseObject) e.NewEvent.Properties["TargetInstance"].Value; string processName = targetInstance.Properties["Name"].Value.ToString(); Console.WriteLine(String.Format("{0} process ended", processName)); } private void ProcessStarted(object sender, EventArrivedEventArgs e) { ManagementBaseObject targetInstance = (ManagementBaseObject)e.NewEvent.Properties["TargetInstance"].Value; string processName = targetInstance.Properties["Name"].Value.ToString(); Console.WriteLine(String.Format("{0} process started", processName)); } </code></pre> <p>You would then call either WatchForProcessStart and/or WatchForProcessEnd passing in your process name (eg "notepad.exe").</p> <p>The ManagementEventWatcher object is returned from the two Watch* methods as it implements IDisposable and so you should call Dispose on these objects when you have finished with them to prevent issues.</p> <p>You could also change the polling value in the queries if you need the event to be raised more quickly after the process has started. To do this change the line "WITHIN 10" to be WITHIN something less than 10.</p>

    1. COThis code could be refactored, but I have left it verbose to hopefully aid understanding

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.

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