BeforeChange(filename, BFP), VIRTUAL
BeforeChange | Update the Audit log file before any file update |
filename | A string constant, variable, EQUATE, or expression containing the label of the file that is to be audited. |
BFP | The label of a BufferedPairsClass object. See BufferedPairsClass for more information. |
The BeforeChange method saves the values of the record before a change is made. These values are used for comparison after the record is saved back to disk.
Implementation:
The BeforeChange method sets the Action property and saves the current field values to the log file. This method is called from the DbChangeManager.CheckChanges method.
