How to set/get document Custom Properties?

[DSSavant]

In Acrobat, select Properties from the File Menu. The Document Properties dialog is now showing. Select the Custom tab. Here I am able to add/delete "Custom Properties". This is nice because it allows me to store information in the PDF that I can then refer to on a later date (problematically that is).

I'm at a loss of how to do this with the Viewer SDK or even the Viewer itself.

If not doable then maybe you can help me solve this problem -- I need to store Key/Value information in a PDF such that I can reference it at a date. I will not always be on the same machine or in the same universe. The information must be stored in the PDF. Storing something in a hidden annotation is not appealing for obvious reasons. Ditto for using Form Fields for storage.

Any ideas?

Hello DSSavant

I believe I have seen this question before, but I think the answer then was that it is not possible with our Viewer (or SDK for it).
I will ask the dev guys again today, and see what they can say on the topic.

Best,
Stefan

Anything from the Development team on this item yet?

Hello DSSavant,

Asked again, and will try to get the answer in the next hour.

Hi DSSavant,

Got the answer directly from the project leader, and I am afraid that it was:
"There is no way to achieve this with our products"

Best,

I understand. I will figure out a nasty hack to work around this.

Please consider this a request to add it. The ability for document systems to store metadata in a PDF for auditing, history, security, etc., is huge.

Ok

And please don't forget to share this (so we can all see how nasty it is )

Cheers,
Stefan

Hi, DSSavant.

Please consider this a request to add it. The ability for document systems to store metadata in a PDF for auditing, history, security, etc., is huge.

Please wait for V3, you will be able to do it in the new version only.

Currently there does exist another way: you may use XCPRO40.DLL library from our PDF-XChange Tools API (https://www.pdf-xchange.com/product/pdf-tools-sdk) to store/restore your custom data (atrings, numbers, arrays, streams) to/from pdf-document.

HTH.
