Open PDF Password Protected File

[amartinez988]

Hi Developers,

I have a PDF file that I need to open to later combine with other PDF File (Combining two PDF Files in one). The code to do this is pretty much done and everything is working fine until I realized that some of the PDF Files have passwords.

So far I have a AcroPDDoc Object. When I try to use its Open method it only accept String Path as a parameter and it doesn't accept a password to open it.

Any ideas or suggestion in how to do this.

Thanks a lot in advance.
