Hello,

I am using the Quick PDF Library during the Trial Period. I filled a given Form (used as a Template) with the SetFormFieldValueByTitle Property. That works so far. A new flattened PDF-Form will be created. When I opened the new PDF File with lets say Acrobat Reader and close it immediatly I was asked "Would you like to save changes Yes/No/Cancel".

What changes could that be? This dialog makes me a bit nervous.

Greetings Tom

If you are flattening formfields then it is most likely there are some fields still present and the NeedAppearances flag is still turned on so Acrobat is attempting to update the appearance streams.

The following line after your LoadFromFile call should fix the problem.

QP.SetNeedAppearances(0);

To remove all the formfields you could do the following

for (int i= QP.FormFieldCount(); i>=1 ; i++) // for I = QP.FormFieldCount downto 1

QP.DeleteFormField(i);

Hi Tom!

Flattened or not ... there are still fragments from a form type pdf
inside the content and acrobat is searching for it and gives you
the warning message.

Cheers and welcome here,
Ingo

Hallo AndrewC,

thank you for your help. I inserted the DeleteFormField() Command and now it works very well. It seems that the SetNeedAppearances() is (in my case) not necessary.

Thanks to all.

Tom
