C++ - CLSID

A universally unique identifier (UUID) that identifies a type of COM object. Each type of COM object has its CLSID in the registry so that other applications can load and program the CLSID. For example, a spreadsheet might create worksheet items, chart items, and macro-sheet items. Each of these item types has its own CLSID that uniquely identifies the item type to the system.
