As far as I am aware it is not possible to pass a list of files to this dialog using any API in Acrobat.
You could however create your own VB .net application that has a mutli file select dialog box and the use the JSObject to merge all those files and open the resultant file in Acrobat.
Please note that using the Acrobat SDK requires the Acrobat program to be installed and it will also need to be running in order to convert the files.
Hope this helps
Did you find any solution for your problem?
I'm searching a solution for a similar problem:
- in an external program I have list of files (pdf, Word, Excel, ...) stored on the file system
- I want to send this list of files to the combine/merge dialog of Acrobat Pro (shell, command line, automation, ...?)
- now the user may work within Acrobat (reorder the files, create pdf, save)
Thanks for any ideas.
