hi, I have protected a PDF file with "Document Open Password", this is beacause I would like to open it only from a VB app. I have used this code to open non protected files...

Dim App, Doc As Object
Set App = CreateObject("AcroExch.App")
Set Doc = CreateObject("AcroExch.AVDoc")

App.Show
Doc.Open "C:\1.pdf", "1.pdf"

I have also used ShellExecute, but these dont work.

Can anybody help me? Thanks a lot.
