Yes, there are other ways to determine the modified state of a Write Pro
object, but they all need to be managed by the developer (store the initial
state in a global for later comparison) so it’s not a boolean flag manger by
4DWrite.
Jeremy French points out on the 4D Forum that the wk date m
If this is necessary to do, it's unfortunate that one has to roll this
functionality themselves. Especially since one could do this with the older

Thanks for the comment Bernd. I should try again.

What was the problem? It´s as easy as
$oMyWriteProObject.MyNewProperty:="Something".
I find that very useful.
You have to keep in mind that object properties are case sensitive, so
MyNewProperty and
Just for reference I am adding an (Form event=On After Edit) to my Write Pro
object. This way any edit to the file will trigger a dirty event. Then I will
probably need to reset the dirty flag upon saving. Otherwise I will wind up
with hundreds of copies of the same document.

That’s correct. It’s not part of the Write Pro object.
Initially I tried to add an attribute to the WP object, but wasn’t successful.
I’m a ‘baby programmer’ with objects so I don’t know whether its possible to
add attributes to a Write Pro object. My limited efforts failed.

As I read over my post, I realized that the last line of
WP_information_isModified method could be simplified. See below..

Reading in deeper. The WP_Information is a session variable object that keeps
track of the WP Pro object is not the actual WP Pro object. Just asking to
clarify.

Thanks. I think that gives me a good direction in how to address it. I just
will need to add an event catch that changes the state to dirty if the state
changes.

Hi Eric,
If I understand your question correctly, I think you’re looking for a “dirty”
flag. As far as I know there is no built in function that track this, so you’ll
need to create your own.
Below are the three methods I use to track the state of a Write Pro object. It

I have a series of records and want to detect whether the 4D Write Pro object
has been changed since it was loaded. This way I can keep a version archive of
older versions of a document available. Is there an easy way I’m not seeing to
know if the Write pro object has been changed since it was c
