I assume you are using remote views in your form's DE since you refresh those controls for a record.
I also assume you have set views' WHERETYPE as Primarykey and Updatable since you regard the whole record, not a field as the basis to lock. To make it more flexible, you could set views' Wheretype to Primarykey and modified, so that a user could edit the last_name field while another user could edit the first_name field in a CUSTOMER table, for example. It requires to change the keyfield of lock table to any_field_in_edit to hold the name for bother primary key and other updatable fields.

But what could I use such a logic when I use SPT, not remote views? Maybe I will have to use keyfield in lock table, not any_field_in_edit, unless there is a way to do a similar setting as WHERETYPE. But is it possible for SPT? Please comment.

> if the user crashes whilst in edit mode it will leave a record in the lock table, but you can build a maintenance form to allow the clearing of these. This is where the datetime column comes in, so you can check how long the locking record has been on.

So, I have to define a rule to delete any long time record in the lock table, such as 5 or 10 minutes. But it is not easy to define it.

Nilson
