I have a simple logon script on my Windows Server 2016, which writes data to a db whenever a client connects.

On this server i have published an application, lets say for example microsoft paint.

The client then can use this application remotely once he has set up the connection in Control Panel -> Remote App and Desktop Connections.
Remote app, in our case microsoft paint then shows up in the start menu.
If it is opened a normal remote desktop connection is established and microsoft paint opens remotely.

Now what i want is to get the name of the application, name of the client, time when application is opened and the time when the application is closed and write everything to a database.

The wtsapi32 should provide the functionality i need in retrieving the application name. Inside WTS_INFO_CLASS there is a property WTSApplicationName.

Unfortunately it always returns an empty string.
Other properties like WTSClientAdress return the expected results.

Is there any other way of retrieving the Application Name?

Any help would be greatly appreciated!
Thanks in advance.
