Remove Lotus Notes design element inheritance programatically

Question

As part of an effort to create a rudimentary revision control system, I would like to programatically disable design element level inheritance on a Lotus Notes template. I have so far tried the following:

• DXL export (ForceNoteFormat=true) + XSLT. This failed with a validation problem in the importer, on fields(!).
• DXL export (ForceNoteFormat=false) + XSLT. Seems to work, but I'd rather not use a DXL solution for something this general.

An area I would like to explore:

• Loop over all (design) Notes, remove the $Class item.

Does anybody have a suggestion on how to do this, or another approach that will remove inheritance?

Answer 1

The following sub seems to work, it removes the flag from any design element a 7.0.3 client can produce. I got the clues about NotesNoteCollection from Ian's blog entry on the same subject:

Private Sub clearDesignInheritance(db As notesdatabase)
 On Error Goto errorthrower

 Dim nc As NotesNoteCollection
 Set nc = db.CreateNoteCollection(True) ' Select all note types...
 nc.SelectDocuments=False ' ...except data documents.

 Call nc.BuildCollection

 Dim noteid As String
 noteid = nc.GetFirstNoteId

 Dim doc As notesdocument

 Do Until noteid=""
  Set doc = db.GetDocumentByID(noteid)
  If doc.HasItem("$Class") Then
   Call doc.RemoveItem("$Class")
   Call doc.save(False,False,False)
  End If
  noteid = nc.GetNextNoteId(noteid)
 Loop

 Exit Sub
ErrorThrower:
 Error Err, Error & Chr(13) + "Module: " & Cstr( Getthreadinfo(1) ) & ", Line: " & Cstr( Erl )
End Sub
