Example
This sample shows how to get all of the unnamed controls running in an application instance.
//This sample gets all of the unnamed terminal controls running in an instance of InfoConnect.
//Before you run this sample, make sure at least one session is running in a InfoConnect workspace. 
//If more than one instance of InfoConnect is running, the session must be running in the first instance that was started.
