A system uses a resource manager class to allow each task to identify itself and establish OLE links. After each task starts, it calls the resource manager register object method in order to register itself with the resource manager. After registration the resource manager controls the OLE communication when any other task needs to communicate with the task. The system provides a new data object built upon the variant data structure supplied with the Microsoft foundation class (MFC) library. This new data structure is called a getset variant, and it encapsulates the identification of the sender of the data, an access key, used to control access between tasks, the OLE dispatch pointer necessary to access the receiver of the data, and a domain identifier which is used for communication across multiple computer systems.
