Thanks for your responce. I have little knowlegde of Adobe - I'm afraid I don't understand the meaning of 'native list of arguments, or pass the arguments as an object'. Any chance of providing sample code which opens a hidden file called "SampleDoc.pdf"?

I already provided that code in my previous post. In fact, you already posted it on July 26th of last year.

Everything you need to know has already been provided in the previous posts. However, if you do not know how to program using JavaScript, then you're chances of success are extremely low. I would strongly suggest you learn about programming in JavaScript, or hire a consultant to either create the code for you, or walk you through the process of developing it yourself.

You have not answered one of the most critical questions posted here. Where is this code being used? For initial testing purposes it should be done from the console window.

You'll find a tutorial on the console here:

You can use JavaScript to open a PDF file and keep it hidden but in your use case, the document wll also need to be "disclosed" in order to use JavaScript to communicate data between documents.
