I am not referring to the menu option. I want to set and lock the document properties. Setting permissions to "No Change" should prevent it from being modified.

Why would the PDF retain old settings and revert back to old setting when the PDF is resaved?

Hi Ken!

You can set the document properties to prevent this menupoint... or you can prevent the whole menu.

Best regards,
Ingo

I have a process that merges multiple PDF files together, then sets properties for the Author, Title, subject, creator and producer (using the QP.SetInformation() method.

Form fields are filled, using QP.SetFormFieldValue and other field property settings.

PDF Permissions are set using QP.Permissions(Allow Print, no copy, no change, add notes, fill fields, no copyaccess, yes assemble, can print).

QP.Encrypt with a password is used (40bit), then QP.CompressContent() before finally delivering the PDF to the browser.

The file properties in Acrobat diplay exactly what I set until the user does a "save as", after which the properties revert back to what the original file used to have.

How is it that the old properties are still in the file? Shouldn't securing the PDF prevent changes like this? How can these be locked down?

Any insight is appreciated.

Thanks,

KEN
