摘要： A condition detected by a virtual routine may be treated by setting an error code or raising an exception, depending on circumstances. Enhanced vtable layouts promote availability of both error-ID-based and exception-based virtual routines, while maintaining compatibility. Compilers treat virtual routines based on their circumstances. One enhanced vtable includes error-ID-based routine pointers in a COM-layout-compatible portion and exception-based routine pointers in an extension. For a virtual routine not overridden by a derived class, a compiler generates a direct call. For an object instance of a specific type, the compiler generates a direct exception-based call for the object's routine. For a factory-sourced object's routine, the compiler generates a virtual exception-based call. When the virtual routine belongs to a component having an enhanced vtable, the compiler may generate a virtual call using the exception-based routine pointer. Code wrappers between COM and native format may also be used.

摘要： A system and method for facilitating simulation of a computer program. A program representation is generated from a computer program. A simulation of the program is performed. Simulation may include applying heuristics to determine program flow for selected instructions, such as a branch instruction or a loop instruction. Simulation may also include creating imaginary objects as surrogates for real objects, when program code to create real objects is restricted, or fields of the objects are unavailable or uncertain, or for other reasons. Data descriptive of the simulation is inserted into the program representation. A visualizer may retrieve the program representation and generate a visualization that shows sequence flows resulting from the simulation.

摘要： A method and user interface for informing a user of the status of a network connection are provided. Conventionally, the “connected” icon in the system tray only informs the user that the computer is linked to a network medium, such as an Ethernet or wireless access point. This icon does not indicate whether a routable IP address has been obtained. In this invention, an icon is used to inform the user that the network connection is disabled, connecting, connected (routable IP address obtained), or in a warning state. The warning state indicates that a non-routable IP address (e.g. autonet address) has been obtained, which will likely be unsatisfactory to the user. However, when connected to an 802.11 ad-hoc network, or when IP status checking is disabled, a non-routable IP address is deemed acceptable, and thus the “connected” icon is displayed.
