Controlled devices according to a device control model maintain a state table representative of their operational state. Devices providing a user control point interface for the controlled device obtain the state table of the controlled device, and may also obtain presentation data defining a remoted user interface of the controlled device and device control protocol data defining commands and data messaging protocol to effect control of the controlled device. These user control devices also subscribe to notifications of state table changes, which are distributed from the controlled device according to an eventing model. Accordingly, upon any change to the controlled device's operational state, the eventing model synchronizes the device's state as represented in the state table across all user control devices.

A system for forming and maintaining one or more networks of devices connected to a shared includes processes for: (a) forming a logical network on the shared media; (b) discovering devices connected to the shared medium; (c) assigning (or acquiring) devices to a logical network; and (d) maintaining a logical network. The system also defines a message format and protocol for communication over the shared media. The protocol uses a two-level address scheme (e.g., a logical network ID and a device ID) and defines several message types used to support the above processes and other useful features. A logical network includes an address space arbiter (ASA) and, typically, one or more devices attached to the shared media. An acquisition authority (AA), interacting with the ASA, is required to complete acquisition of a device by a logical network.

A method and apparatus are provided for docking re-sizeable graphical user interface (GUI) boxes to a docking region located along a side of a primary GUI box with which the dock is associated. When a first GUI box becomes associated with a dock so that at least one resizeable GUI box is associated with a row of the dock to which the first GUI box is to be added, the dimensions of at least one GUI box associated with the row of the dock are altered automatically so that the docked GUI box occupies a prescribed length of a row of the dock. In a row containing at least two re-sizeable GUI boxes, a row minor splitter detection region is provided for simultaneously altering the along dimension of at least two of the re-sizeable GUI boxes. In a row containing at least one re-sizeable GUI box, a row major splitter detection region is provided for modifying the across dimension of the row and all re-sizeable windows contained in the row.

A processor (CPU) in the computer system executes an application program made up of a number of components, each associated with a set of commands. While the program is executing, a current operating mode of the program is selected. The processor automatically constructs a dynamic menu for the selected operating mode by determining which of the program's components are active in the current operating mode, merging the commands sets of these active components to form an active set of command for the current operating mode, and organizing the commands of the active set into a menu structure. The constructed, displayed menu items can be selected with an input device. Menu items contained in a displayed application menu bar are revised when one of a number of subwindows displayed by the application is selected. Displayed menu items pertaining to a particular subwindow are included in the menu bar when the subwindow is selected. Add-on software components provides additional menu items to those provided by the application program and their implementations without itself having to modify the application's menu bar to add those menu items or intercept and process user input for selecting these menu items.

A mechanism for locating and calling an appropriate member function to process a message or command in an event-based system is provided. An object data structure contains data members and a pointer to a virtual function table. The virtual function table contains pointers to member functions associated with the object. The virtual function table contains a pointer to a member function that returns the address of a message map. The message map contains two entries: a pointer to a base message map and a pointer to an array of message map entries. The array of message map entries contains the addresses and parameters of member functions. A default window procedure member function searches the array of message map entries to locate a desired member function. If the desired member function is not located in the array of message map entries for the derived class, then the window procedure member function searches the array of message map entries for the base class of the derived class.
