Topic: How to open a password protected PDF?

We are writing the prototype of a Windows .NET client-server application, written in C#, using the ActiveX control and Acrobat Reader to view password protected PDF files.

The files are protected with password only to prevent modifying the PDF. The end-user will NOT know the password, only the application. How is it possible to open such a file?

The LoadFile() function does only accept one parameter i.e. the file path. It seems not to be possible to pass the password as parameter - a popup window comes to enter it manually.

How is it possible for the application to open the file?

This internal application will be used by more then 20000 users and has to be reasonably expensive, that is without royalties for each terminal.

I will be very grateful for any advice, solution or even criticism of the way of thinking.
