Hi,

We've been using EO.PDF for a while (we're on version 3.0.94.2 - 2011.2) and have hit an issue today when trying to encrypt existing PDF files. Here's the code (VB.Net):

Private Function zEncrypt(PDFFileIn As String, PDFFileOut as String, Password as String) As String
'Encrypt the supplied PDF and save it to the supplied location
Dim PDFIn As EO.Pdf.PdfDocument
Const OwnerPW As String = "Password"

'Load the PDF file
PDFIn = New EO.Pdf.PdfDocument(PDFFileIn)

'Create a PDF file with user password and owner password set.
PDFIn.Security.UserPassword = Password
PDFIn.Security.OwnerPassword = OwnerPW
PDFIn.Save(PDFFileOut)

Return PDFFileOut

End Function

Shortly after the creation of the encrypted PDF the software attempts to rename the directory that it is in and we're getting the following exception:

System.IO.IOException: {"Access to the path '{PDFDirectory}' is denied."

If the PDF file is simply copied to the new location, it all works. There's only a problem if the PDF is encrypted en-route to the new directory.

It is not possible to rename the directory in Windows Explorer either. Explorer shows a dialogue stating that "The action can't be completed because the folder or a file in it is open in another program."

I can't see a method for closing the PDF after the save or disposing of the object...any ideas?

Thanks,

Chris.
