  • MANAGING EXTENSIBLE VALUE TYPES IN SPREADSHEET CELLS
    Publication number: 20090006466
    Abstract: Individual cells within a spreadsheet may contain an extensible value as defined by an extensible value type. The extensible value type is a third party user defined value type that is incorporated into the spreadsheet as a supported data type. When the extensible value type is defined, an associated set of functions are developed to operate on the type. The spreadsheet manages instances of these extensible values such that they are properly maintained by the spreadsheet application while in use and released from memory when they are no longer in use.
