Opening Password protected pdf through code

Hi Guys,

I need to create a script in vbscript for opening a Password Protected pdf file. The file needs to fetch the password from a notepad.

How can i Automate the code for opening the file n number of times without the 'Password' window getting displayed every time. Is their any function available which can verify the 'Password' at back end and the 'Password' window does not gets displayed.

I have Adobe Reader 9 installed on my machine so can not use CreatObject("AcroExch.PDDoc"). I do not want to use Shell,

I need the code in vbscript., Please help.

Thanks in Advance!!
