Class DVRecord

This record is part of the Data Validity Table. It stores data validity settings and a list of cell ranges which contain these settings. The "prompt box" appears while editing such a cell. The "error box" appears if the entered value does not fit the conditions. The data validity settings of a sheet are stored in a sequential list of DV records. This list is preluded by a DVAL record. If a string is empty and the default text should appear in the prompt box or error box, the string must contain a single zero character (string length will be 1).
