PDF Printer Driver, Convert to PDF, Print to PDF
Example 1: Merge several PDF files (VB.Net)  

   Dim NVmerge : NVmerge = CreateObject("PDFMerge.Neevia")
   Dim retVal : retVal = NVmerge.MergePDF("c:\1.pdf+c:\2.pdf", "c:\merged.pdf")
   If retVal <> 0 Then
     MsgBox("Error code=" & CStr(retVal))
   Else
     MsgBox("Done")
   End If


I was looking for a product that could place watermarks on very large PDF files (some of them over 30 thousand pages) in as less time as possible. After testing many tools I found Neevia PDFstamp. It did the job!
