This property indicates whether an object is active. At run time, all objects defined in a project return True in this property until the Deactivate method is used in it or in one of its parent objects. Objects created at run time using the AddObject method configure this property according to the Activate parameter of that method. In case of pre-activated objects in Hot-Standby, that is, the objects configured in the Pre-activated services in backup server option of the Options tab on E3 Admin's configuration window of a Domain, have this property configured in False until the backup server assumes the execution of the Domain.
