Convert Lotus Notes Documents to PDFs with LotusScript and Microsoft Word

In some of our old databases we wanted to convert the NotesDocument itself to a PDF-A Documents for archiving purposes.

We did it until now by opening the NotesUIDocument in the client and converted it ot PDF-A with an PDF-Printer (PDF-Creator). But often these NotesUIDocuments did note closed correctly and at the end of the NotesAgent we had thousands of NotesUIDocuments opened in the Client…

We searched for another way to convert the NotesDocument. We tried to render it to an NotesRichtTextItem, converting it to an MimeItem (based on the work from Yuri (here…), generating some HTML. But the HTML had some glitches: Notes inserts a small transparent gif into empty table-cells, so we would have to deal with different MimeEntities wich is also a PITA.

Then I found some code (from Steven J. Knight) in the IBM-Forums wich called a Notes-API function to export Microsoft RTF (which is called by the @Command([ExportFile], „Microsoft RTF“, fileName)

This works as a charm, generating nice looking RTF-Files. Together with a Microsoft Word COM-Instance we convert it to PDA-A quite fast and reliable:
