AssignLeftToBuffer
The AssignLeftToBuffer method copies the contents of each “left” field to its corresponding “buffer” field in the RealList property.
Implementation:
The “left” field is the first (left) parameter of the AddPair method. The “right” field is the second (right) parameter of the AddPair method. The BufferedPairsClass automatically supplies the “buffer” field.
Example:
Fields.AddPair(CUST:Name, CustQ.Name) !establish Name pair
Fields.AddPair(CUST:Phone, CustQ.Phone) !establish Phone pair
Fields.AddPair(CUST:ZIP, CustQ.ZIP) !establish ZIP pair
!some code
IF ~Fields.EqualRightBuffer !compare QUEUE fields to save buffer
CASE MESSAGE('Abandon Changes?',,,BUTTON:Yes+BUTTON:No)
OF BUTTON:No
Fields.AssignRightToLeft
OF BUTTON:Yes
Fields.AssignLeftToBuffer
END
