Hi ! In my GUI i hava a pop-up dialog that allow the user to book room. My question is: Is it better to try to lock when the pop-up window creates(risk that the user forget the window and tge record is locked) or lock when the user is finished with writing the owner name(risk for overwriting)?
I think it would be better the minimise the amount of time after locking a record. In my project, I didn't display a dialog for booking (handled on the main gui) but if I did; I would do the booking after the dialog but also check for record inconsistency (making sure the record key is not changed).
