ResetFromAsk( request, response ), VIRTUAL, PROTECTED
| ResetFromAsk | Resets the BrowseClass object following an update. |
| request | A BYTE variable that indicates the type of update requested. Valid updates are insert (1), change (2), and delete (3). |
| response | A BYTE variable that indicates whether the requested update was completed (1) or cancelled (2). |
The ResetFromAsk method resets the BrowseClass object following an Ask or AskRecord update to a browse item.
Implementation:
The Ask and AskRecord methods call ResetFromAsk as needed to reset the BrowseClass object.
ResetFromAsk FLUSHes the BrowseClass object's VIEW if needed, calls the appropriate “reset” method (ResetQueue, ResetFromFile, or ResetFromView) to refill the QUEUE, then carries out any pending scroll request made concurrently with the update. See WindowManager.VCRRequest.
EQUATEs for the request parameter are declared in \LIBSRC\ABFILE.EQU as follows:
InsertRecord EQUATE (1) !Add a record to table
ChangeRecord EQUATE (2) !Change the current record
DeleteRecord EQUATE (3) !Delete the current record
EQUATEs for the response parameter are declared in \LIBSRC\ABFILE.EQU as follows:
RequestCompleted EQUATE (1) !Update Completed
RequestCancelled EQUATE (2) !Update Aborted
Example:
BrowseClass.Ask PROCEDURE(BYTE Req)
Response BYTE
CODE
LOOP
SELF.Window.VCRRequest = VCR:None
IF KEYCODE() = MouseRightUp
SETKEYCODE(0)
END
IF SELF.AskProcedure
IF Req=InsertRecord THEN
IF SELF.PrimeRecord()
RETURN RequestCancelled
END
END
Response = SELF.Window.Run(SELF.AskProcedure,Req)
SELF.ResetFromAsk(Req,Response) !reset the browse after update
ELSE
Response = SELF.AskRecord(Req)
END
UNTIL SELF.Window.VCRRequest = VCR:None
RETURN Response
