How to open PDF in Acrobat 9 without displaying the Acrobat window

[Atin Wadehra]

Am using IAC in Windows XP via VC++ to open and modify PDFs in memory without displaying the Acrobat window so as to the PDF Processing in the background. To open the PDF, have to call the method PDDoc.OpenAVDoc which opens the Acrobat window for displaying the document.

As a workaround, I tried to minimize and hide the Acrobat viewer, using the AcroApp.Minimize and AcroApp.Hide methods. However opening, minimizing and hiding the viewer is creating a flickering effect (Acrobat window coming and going) especially when a no of PDFs have to be processed in a loop.

If I use only PDDoc.Open without the call to OpenAVDoc, am getting an error "No form is open in the Acrobat viewer".

Can anyone suggest a workaround to open and process PDFs in memory without displaying the PDF.

To open the PDF, have to call the method PDDoc.OpenAVDoc




Only if the methods you're using are only available to AVDocs. If the methods you're using are PDDoc methods, Acrobat doesn't need to be visible.

If I use only PDDoc.Open without the call to OpenAVDoc, am getting an
error "No form is open in the Acrobat viewer".




What method is giving you this error? If it is part of the AVDoc class, then yes, it needs to be open in the viewer.

Design your program workflow to only use PD layer methods. If you use AV layer methods, the Acrobat viewer needs to open the document.

PDL,

Am getting the Error "No form is open in the Acrobat viewer" while trying to instantiate fields list inside the form via an AcroForms object. The problematic code snippet is given below

iPDDoc->Open("PDFFileName")

iAVDoc->AttachDispatch(PDDoc->OpenAVDoc("PDFFileName")), true);

ipFormApp->CreateDispatch("AFormAut.App", &OleExc) pFields = new IFields(pFormApp->GetFields());

The GetFields method is giving error in Acrobat 9 but its working fine in Acrobat 7 and 8.

Since the AV layer methods are working fine in Acrobat 7 and 8, please let me know why they are not working in Acrobat 9 and if there is any workaround.

Also, if I use only PD Layer methods, can I access the form fields inside the PDF?
