Example 1: Sign a PDF file with an invisible signature (Visual Basic)  

   Dim NVsign : Set NVsign = CreateObject("Neevia.PDFsign")

   NVsign.CertificateSubject = "Test certificate"
   NVsign.CertificatePassword = "password"

   NVsign.Reason = "I am the creator of this document"

   NVsign.Invisible = true
 
   Dim retVal : retVal = NVsign.SignPDF("c:\in.pdf","c:\out.pdf")
   If retVal <> 0 Then
      MsgBox("Error code=" & CStr(retVal))
   Else
      MsgBox("Done")
   End If

Neevia PDFstamp is the right tool in case you need to programmatically stamp batches of PDF files with multiple watermaks. It is fast and cost effective!
