Using QuickPDF Library 8 and Delphi 7

My product allows users to create forms in Acrobat Professional (saving them with Reader Extensions enabled), store the resulting form as a template in our repository, and eventually serve it up to the user in Acrobat Reader for filling out fields. We use QuickPDF to manipulate the saved PDF and mine data from the populated form fields.

What we found is once we save our form through QuickPDF further attempts to display the form in Acrobat Reader result in a warning dialog from Adobe that states:

"This document contained certain rights to enable special features in Adobe Reader. The document has been changed since it was created and these rights are no longr valid. Please contact the author for the original version of this document."

When this message appears, the Reader Extensions that were previously enabled in Acrobat are disabled and our form can no longer be modified (in Reader). We thought perhaps a particular task we were doing in QuickPDF may have caused this so we backed out all of our processes, until only QuickPDF's Load and Save operations remained.

I understand that this message is being generated by Adobe's software and not QuickPDF, but obviously the Save operation from QuickPDF does something that allows that message to be triggered. Is there any way (other than to avoid using Acrobat Reader) that you know of to prevent this from occurring? My fear is our users seeing this "changed" message and believing that something corrupted the forms they receive from our software.

Thank you.

Hi Rich!

I think all here knows it that you shouldn't save a acrobat form if you want to work on it later with acrobat again :-( That's adobes money machine ;-)
If you save these forms with Foxit the same issue happens.
Please read my blog regarding this case:

Cheers and welcome here,

Hi Ingo,

Nice blog post. I wish I stumbled upon it about 6 months ago, before I started trying to accomplish the "simple" task of designing a real-world workflow around the use of PDFs.

I, unfortunately, have a business requirement that I need to fulfill which requires PDF form usage AND the ability to fill in a form, save it, and re-open it later for further editing. I am dealing with medical documents that require multiple people to complete and sign. Quite often, the second user of the form isn't physically (or legally) able to sign the form until days after the first person filled the form out.

I have tried to introduce other products like Foxit (which I really liked) into the equation to get around some problems but I can't force my users to all download and install Foxit to make our solution work. I tried to purchase their SDK but it is WAY too prohibitively expensive. I even tried to purchase the SDK from Adobe but they won't return my calls to even give me a price.

Any tips for a solution that will allow users to edit and save a PDF document multiple times?

Hi Eric!

The issue has to do with pdf-forms if you manipulate normal pdf-documents adobe's reader won't tell anything.

Hi Rich!

My idea to avoid these problems:
Adobe doesn't like if you manipulate pdf-forms made by adobe-products with third party products. So you should create images from each form (pdf to image) and extract the complete data (properties and content) of all form-fields.
With the images you can create new pdf-pages and put the form-field-data with the content on it.
Now you'll have new pdf-forms and adobe products won't realize that they were modified.
I'll make a component one day doing this in one step ;-)

Cheers, Ingo
