I want to write a program that can open a encrypted pdf file. I have the password to open but I don't want the users to see the password, so others won't be able to open the pdf without the program I wrote. How can I use parameters correctly to do what I want?

I tried [AcroRd32.exe /a "password=10293810" "c:\h.pdf"] but doesn't work. It still requires user to input a password.

Thanks

There is no command line option for passing a password to Reader, or any other means short of creating a custom plug-in, which Adobe probably wouldn't allow anyone to create for Reader. Consider using certificate security.

The only way I can think of is through a custom-made stand alone application that will open the PDF and then paste the password. If you're interested, I can create such a tool for you. Contact me by email or PM me.
