Index/catalog & encrypt PDF files

Question

Hi,
I wish to archive thousands of PDF invoices. I can do this quite easily by putting them on a CD or DVD and creating a catalog Index... however I also wish to encrypt each document and password protect it. Again this is easily achieved by creating a batch process to add Security. When I have done this the catalogue index does not work anymore - it doesn't work either when I select "Encrypt all documents except metadata (acrobat 6 and later compatible)".
Does anyone know how to index/catalog & encrypt PDF files?
I use Vista SP1 & Acrobat pro Extended 9.0.0
Thanks.
Elfed.

Right of course, I'm a little tired this morning.
I copied over my new js file(s) to the C:\Program Files\Adobe\Acrobat 8.0\Acrobat\Javascripts folder.
Now that I have done that, I run the following code and get the error shown at the bottom:
 Type AcrobatCAcroAppType;AcrobatCAcroAppType =
Type.GetTypeFromProgID("AcroExch.AVDoc"); 
CAcroAVDoc avDoc = (Acrobat.CAcroAVDoc)Activator.CreateInstance(AcrobatCAcroAppType); 
Type AcrobatPDDocType;AcrobatPDDocType =
Type.GetTypeFromProgID("AcroExch.PDDoc"); 
CAcroPDDoc pdDoc = (Acrobat.CAcroPDDoc)Activator.CreateInstance(AcrobatPDDocType); 
try
 if (avDoc.Open(fileName, "")) //open the PDF
pdDoc = (CAcroPDDoc)avDoc.GetPDDoc(); 
Object jsAcroObj = pdDoc.GetJSObject(); 
Type T = jsAcroObj.GetType(); 
object[] saveAsParam = { "test" };T.InvokeMember(
"TestFunction", BindingFlags.InvokeMethod | BindingFlags.Public | BindingFlags.Instance, null, jsAcroObj, saveAsParam); 
Console.WriteLine("\tExport complete."); 
if (avDoc.Close(1) != true) avDoc.Close(1);}
else Console.WriteLine("Cannot open: " + fileName);}
catch (Exception ex){
Console.WriteLine(ex);}
Code fails at
T.InvokeMember line with the following error:
System.Runtime.InteropServices.COMException (0x80020006): Unknown name. (Exception from HRESULT: 0x80020006 (DISP_E_UNKNOWNNAME))
