OnChange event in a service application
Question / Problem
I have a little problem, trying to use the TShellChangeNotification in a service application: The OnChange event isn 't triggered in this situation
Answer / Solution
The SHChangeNotifyRegister API of Windows doesn't seem to work in a Windows System Service. Although Microsoft's documentation doesn't state this, we found several postings in the internet that suggest that this API doesn't work for service applications.
