dll for merging pdf files

What is needed is a dll for merging pdf files. Should have these methods: 1. AddFile (path) 2. Merge (path) the addfile will add the pdf file to a collection. When the Merge is used, will need the path of the new pdf file. Each pdf file should have a page seperator. Therefore, if there are 5 files that are one page each, then the final results would be 5 pages on one file. This can be done in either VB, C++ or Delphi. However, it needs to be COM enabled and be able to be called from VB 6.0.
