Sorry, forgive the previous errant send... here's the complete post: I followed the path within the database's preferences and the checkbox for "Structure File" is checked off.

I know that > if you simply changed one field type to another, with no other change > to the tables, this type of change is also NOT an issue to roll back. 4D is very forgiving when dealing with a data file that does not exactly match a structure file. If the data file has fields in a table, and your structure file does not have those fields, as long as you don’t load and save a record in that table, the data in the fields is safe. As soon as you load a record from the data file, 4D will compare it to the structure definition for the table. Any fields not defined in the structure file are ignored. Any fields that have a different type (like Alpha in the data file and Longint in the structure file) will automatically be converted as best as 4D can to the type that the structure file defines. If you then SAVE RECORD that record back to the data file you get all these changes. Unknown field’s data is lost, different field types are written back to the data file based on the structure file type. As far as a table in the data file that is not defined in the structure file, it also survives. You can’t access the table because it does not exist in the structure file. But the data stays in the data file. It’s basically orphaned. But, if you were to take that same data file and open it up with another structure file that does have that table defined, then the data is still there and accessible again. That’s the basics. I don’t know of any other database system that implements data files, records and field type changes the way 4D does. It really is a beautiful thing when you have a system that is changing and you are moving around between different versions. The trade off to this “beautiful” system, is performance. It takes extra time with every record load to do the field-by-field comparison and data type conversion if necessary. But with the hardware of today, it’s really a non-issue. No noticeable performance penalty. In the 4D world, any performance tradeoff is easily accepted for the benefits it can provide.

Re: Forms Stop Receiving Certain Events
the configuration is pretty simple.
Open the database, go to:
Database settings : Backup : Configure
turn on the check box(es) you want to be backed up and add any
additional file(s) you want
set your destination, and schedule.
the .4BK file obtains whatever is supposed to be backed up.
The 4BL is a log file, and I assume tells 4D what is supposed to be in
the 4BK film and how large.
To restore:
Open 4D
Fiel menu : Restore
Select 4BK to restore, and select a destination
wait
if, as default, structure and data are included you will have a
functional database, and structure.
As for reading -- the documentation RTFM :)
not that I do :)

Re: Forms Stop Receiving Certain Events
I’m glad to learn that. However, the way our backups are configured I only see
4BL (the log) and and 4BK (the data) files. Looks like I need to learn more
about the backup configuration process. What is the recommended way to
configure backups so that I would have access to these individual files? Or,
are they accessible individually during the restore process from the 4BK file?
Also, if there is any good reading on this you could point me too, It’d be
appreciated. Thanks for your response, very helpful indeed!

Re: Forms Stop Receiving Certain Events
Krik,
I just checked, and On Clicked and buttons does work regardless of form
event, but I think this depends on the event. I know some events, like
On Timer, On Before/after Keystroke will not work if the form event is
not checked at the form level.

depending on what your form method looks like, it does not hurt (much)

Re: Forms Stop Receiving Certain Events
this is not correct. The structure (.4DB) is a separate entity from the data (.4DD) Other then having added tables and/or fields, rolling back the structure to a previous one (say yesterday) is simple and is not a significant issue. If you have added fields and/or tables then there can be issues, however, I am not well versed in this part of a roll back. I know that if you simply changed one field type to another, with no other change to the tables, this type of change is also NOT an issue to roll back. To the problem of not responding, I have seen 2 things with this. - something inside 4D has simply gotten FUBAR(tm) and a restart of the program (4D & database) will resolve it - there are 1 or more in obvious interface objects interfering with the expected behavior of your form. ex: you have a (supposed) back ground object as part of the form appearance (say a box with no fill) and this box has "moved" to the foreground. The box then receives all the interface actions (clicks etc.) and the intended entry objects (buttons for example) do not appear to function. Summary - check your 'Z' stacking of objects.

Re: Forms Stop Receiving Certain Events
Hi Sandor,
Form object form events are not linked to the form's events. So the events
a button responds to aren't limited by what the form does.
If the button is invisible, perhaps disabled - I have never tried - it
won't execute until it's visible. So a button that's invisible to start
will never run On load because a button's On load runs before the Form's On
load event.

Re: Forms Stop Receiving Certain Events
OK, so it looks like there's some strange bug I ran into. For some reason most
of the events for my forms got disabled at the form level. So, even though
they were checked off at the element level the form was not registered for
those events anymore. I am going to have to go through all the UI elements and
look though their event handling code to make sure all the correct events are
registered at the form level.
Has anyone heard of this before? If anyone knows of a way to best determine
the previous state of the form event configuration any thoughts would be
appreciated.

Subject: Forms Stop Receiving Certain Events
Has this ever happened to anyone? UI Elements on certain forms appear to have
stopped receiving certain events. This form and related code that have been
functioning for many many years. I was adding an additional page to the form
when this started happening. I did not edit or change the code or properties
on any of the other pages/ui elements. Any help in tracking down the cause
would be helpful and greatly appreciated. I do have backups but I don't want
to roll back the database because it is an active database where data is added
every day. I am under the impression that you cannot roll back the interface
programming separately from the actual data. An example is below.
Platform: MacOSX (10.11.6)
4D Version: v15 R5
Here's an example…
A Popup button, has 'On Load', 'On Clicked' and 'On Unload' enabled in the
property list (i.e. checked off').
The object method for the popup has a case statement for reacting to these
events. (The rest of the code is removed for brevity)
$TheEvent:=Form event
Case of
: ($TheEvent=On Load)
ALERT("Load")
: ($TheEvent=On Clicked)
ALERT("Clicked")
: ($TheEvent=On Unload)
ALERT("Unload")
End case
The only alert that is displayed is the unload alert.
How can I figure out where this the events are being lost/swallowed.

Has this ever happened to anyone? UI Elements on certain forms appear to have
