Jens-B. Augustiny from LigoNet.ch posted a sample database to show. how you can access OpenOffice or Symphony from within LotusScript by using the COM-UNO Bridge, that comes with these two products.
The database in fact contains an application, which almost immediately with some small modifications may be used to create invoices, that will be generated through OOo/Symphony.
If you do not look that often into OpenNTF’s CodeBin like I do, then you might have missed this entry. David J Montalvo discovered a yet undocumented method of the NotesDatabase class.
This method allows you to create an empty NotesDocumentCollection without doing workarounds that have beeen used for years like this one from LDD.
I searched mail8.ntf using Notes Design Searcher.
The method is used in 3 agents and one ScriptLibrary. Searching mail85.ntf returns the same result.
There is also an idea on IdeaJam which can be closed once the method is documented in either Notes 8.0.x or in the upcoming Notes 8.5 release.
