Hi,
I get multiple pdf's (up to 1000 per day) that need to be password protected before sending on to various clients. I have Adobe Acrobat installed and tried using the dll which come with it but cannot find a password function. I can create new PDF's (still no password). Does anybody know of a way?

I'm not sure which version of acrobat you are using, but if you go here: http://partners.adobe.com/public/developer/acrobat/sdk/index.html, and download the SDK (you'll have to register for a free account), it comes with sample code of how to automate Acrobat processes with Visual Basic (and C/C++). Download and install the sdk and samples, and I'm certain you'll find what you need.
