A location created by the rdoResultset object for the contents of a row that is open for editing. The Edit method copies the current row to the copy buffer; the AddNew method clears the buffer for a new row; and the Update method saves the data from the copy buffer to the data source, replacing the current row or inserting the new row. Any statement that resets or moves the current row pointer, or cancels the edit, will discard the copy buffer.
