Toran,

UpdateAndFlattenFormField is not designed to flatten XFA fields.  Adobe uses a strange system where it creates FormFields to match the entries in the XFA XML field description.  When the xml is updated it will update the dummy formfield attached to the XFA field so it is not a reliable method to flatten XFA fields.

You can call QP.RemoveXFAEntries to remove the XFA and leave the Acroform fields then you can use SetFormFieldValue to set the formfield.

Here is the code you need to use

            QP.LoadFromFile("i-9.pdf", "");
            QP.RemoveUsageRights();
            QP.RemoveXFAEntries(0);

            for (int i = QP.FormFieldCount(); i >= 1; i--)
            {
                QP.SetFormFieldValue(i, "111");
                QP.UpdateAndFlattenFormField(i);
            }
            QP.SetNeedAppearances(0);  // Stop Acrobat asking to save the file when closing.

            QP.SaveToFile("out.pdf");

no... i only know from the past that it could be difficult dealing with form fields having identical names.
With QuickPDF it's possible to rename fields on the fly while/before processing...

Well, the field names that I posted are returned by QPDF Api. Are you suggesting a QPDF bug in processing field names ?]]> Tue, 22 Apr 2014 02:15:56 +0000 http://www.quickpdf.org/forum/flattening-of-xfa-field_topic2868_post11632.html#11632 <![CDATA[Flattening of XFA field : I think ...&#034;form1&#034;&#...]]> http://www.quickpdf.org/forum/flattening-of-xfa-field_topic2868_post11627.html#11627 Author: Ingo

I think ...
"form1[0]"
"form2[0].#subform1[6]"
"form3[0].#subform2[7]"
... would work.
It's only an idea regarding on similar posts from the past. ;-)

Cheers, Ingo

I am using UpdateAndFlattenFormField method  to flatten XFA fields and the method is failing on some of them. Out of 80 fields (all have similar name structure) the method fails on 3 fields with the names:

"form1[0]"
"form1[0].#subform[6]"
"form1[0].#subform[7]"

Perhaps it also fails on other fields that are subfields of the above fields, but the return value indicate success.

What could be the problem?

Thanks.
