Retrieve path of pdf open in Acrobat DC in C#

[aniketb74878072]

In c#, I have handle of Acrobat DC process instance running, I simply want to traverse through details of PDF documents that are open in it, and retrieve path of all those PDFs using Acrobat DC SDK (InterApplicationCommunication).

For this to start with I went through SDK documentation and Samples provided along with it, but samples are not working, Acrobat.dll included in references is missing, so I went through process mentioned in documentation to add reference but Unable to find Acrobat.dll at Project -> Add Rerences... -> COM, I had installed Acrobat Reader DC v2018.009.20050

Note: I am using VS2013 or VS2015, both of them giving same problem

Not possible with Acrobat Reader. You need Adobe Acrobat.

Acrobat and Acrobat Reader are two different products. Make sure you know the difference.

[aniketb74878072]

Apologies for confusion,

I am using Adobe Acrobat Reader DC

Thanks for clearing that up. The Acrobat SDK is mainly a tool to sell Acrobat, not  for people only with Reader. A few of the IAC interfaces using DDE are available for free but nothing to do what you want. You (and each user using any app you make) must license Acrobat.

Thanks for the info,

I had installed Adobe Acrobat DC and now Acrobat.dll is available in C#,

So now, in order to retrieve foremost pdf document open in an Acrobat DC instance using GetActiveDoc,

I wish to retrieve that active instance of Adobe Acrobat DC, how can I achieve this?

GetActiveDoc

[Bernd Alheit]

Use the function GetActiveDoc.

[aniketb74878072]

Yes, I understand I need to  use GetActiveDoc function, but for calling this, I need object of AcroExch.App, in c# I don't want to create new object, instead I want reference to already opened instance.

AcroExch.App

To use this API you need to know how to use general COM objects in your chosen language. If you are unsure, you should find example on the web of people who have worked out how to use the AcroExch objects from C#. C# was not a target language when the API was created and Adobe do not provide examples of its use.

One more step closer,

I am able to retrieve

     Type PDFType = Type.GetTypeFromProgID("AcroExch.App");
     CAcroApp AcroAppObj = Activator.CreateInstance(PDFType) as CAcroApp;

     AcroAppObj.Show();

     CAcroAVDoc AvDocObj = AcroAppObj.GetActiveDoc() as CAcroAVDoc;

     CAcroPDDoc PdDocObj = AvDocObj.GetPDDoc() as CAcroPDDoc;

Now I have CAcroPDDoc object, but still unable find any library function which returns Path of document, could you please help in this.

                                Type PDFType = Type.GetTypeFromProgID("AcroExch.App");
                                CAcroApp AcroAppObj = Activator.CreateInstance(PDFType) as CAcroApp;

Found it! you have to bridge to JavaScript and use doc.path. See https://acrobatusers.com/tutorials/file-paths-acrobat-javascript  for a discussion of Acrobat paths.

Which part of the answers are not clear? We would only type it out again, because for us that’s the answer.
