Failing to Populate Secured PDF with Excel VBA

Hi,

I have been using the same Excel VBA code below to populate a few PDFs in the past, .

However, when I try now to use the same code for a PDF that has [SECURED] in its file name, when I open it with Adobe Acrobat Pro, it won't work.

I am able to modify this PDF manualy and save the changes I make, but failing to do so with Excel VBA.

Any ideas ?

 

My Code

 

Option Explicit

Dim AcroApp                 As Acrobat.AcroApp

' ===== List of Fields in PDF =====

Sub FMLSSaleAgreementPDFPopulate()

' set the Full path and PDf file name (including extension)

Correct answer Thom Parker

I am not familiar with folder level function.

Do you have a sample of VBA code that does that ?


All top level objects in the Acrobat/PDF JavaScript context are directly accessible through the IAC JSO. So you call the function exactly like you call "getField()".  Just pass in the 3 strings that set the fields. 

 

To define a folder level function do this.

1) Create a plain txt file and give it a ".js" extension.

2) Edit the file to define the function, something like this

 

function SetMyFields(a,b,c)
{
    console.println("Start Set Fields: " + a);
    this.getField("p_Street_Address").value = a;
    this.getField("p_City").value = b;
    this.getField("p_Zip").value = c;
    console.println("End Set Fields: " + b);
    return this.title;
}

 

Call this function in your VBA like this:

 

PDFJSO.SetMyField("Address","City","Zip");

 

Here are instructions on installing a folder level script

https://www.pdfscripting.com/public/Installing_Automation_Tools.cfm

 

And you'll find a tutorial on using the JavaScript Console Window here:

https://www.pdfscripting.com/public/Free_Videos.cfm#JSIntro

 

The console window should report an errors, and of course you'll see the messages from the function that verify the code is being run. In fact. If Acrobat is having a problem with the current code, then there should be a message here.

 

On another note, why are you using the JSO instead of the IAC AcroForm methods for setting form  fields? Doing this would get around the context change the JSO causes.

Where is the failure point in the code? Is the secure PDF actually being opened by the VBA?  

Have you tried manuall opening the PDF in Acrobat and then aquiring the current PDF with the VBA?

There is no fail, the code opens the PDF, the code runs all the way to the end, just the PDF fields aren't populated when running through the lines.

Any idea ?

What kind of security is on the PDF? Password or Certificate? Are there any rights or restrictions on the PDF?

 

I would suggest a slight change to your code, which will simplify the VBA interaction with Acrobat and provide more information about what's going on. 

 

Instead of calling "getField" in the VBA, write a folder level function to set the field values. Then call this function from the VBA. Place "console.println()" statements into this function so you can see directly that it's being called.  And return a value from a document field or property that can be reported in the VBA script. 

 

I don't know what the specifics are for IAC interaction with a secure PDF. I'm sure they depend on the type of security. But I suspect part of the issue may be the indirect nature of IAC. Using a folder level script puts the interaction with the field inside Acrobat. It also gives you a direct way to guarentee the interaction, instead of just not getting any indication of what's going on.
