Par2: Message when cancelling parent but child changed 2001-06-27 -- George Lehman Ok, I have a solution. I searched several directories for code related to
cancel, and found the question is asked in thiswindow.takecloseevent in the
parent call. So I worked up this little template:
#!--------------------------------------------------------------------------
---
#EXTENSION(ChildUpdateCancelWarning,'Force Cancel-Warning if Child record
modified'),PROCEDURE
#LOCALDATA
LOC:ChildRecordModified Byte
#ENDLOCALDATA
#AT (%WindowManagerMethodCodeSection,'Init','(),BYTE'),LAST
LOC:ChildRecordModified = 0
#Endat
#AT(%WindowManagerMethodCodeSection,'Run','(USHORT Number,BYTE
Request),BYTE'),Priority(8000)
IF (GlobalResponse = RequestCompleted) THEN
LOC:ChildRecordModified = 1
END
#Endat
#AT
(%WindowManagerMethodCodeSection,'TakeCloseEvent','(),BYTE'),Priority(2500)
IF (LOC:ChildRecordModified) AND (Self.CancelAction <> Cancel:Cancel) THEN
IF (Self.Errors.Throw(MSG:ConfirmCancel) = Level:Cancel) THEN
SELECT(Self.FirstField)
Return Level:Notify
ELSE
Self.CancelAction = Cancel:Cancel ! Don't ask again
END
END
#Endat
#!--------------------------------------------------------------------------
---
I decided against trying to apply it on a global scale, and just made it
something I have to add to each form that suffers from the problem. Also, I
did not take into account the Cancel:Save branch because I never use that
option.
The middle section is based on code from abwindow.tpl. If anyone else can
use this, please feel free to do with it as you please.
