How do you keep a running history of all entries in an RTF field?

Put this script in the QueryClose event of the document. It will append the RTF field named Details to an RTF field named Details_History:

FIELD Details:
Rich Text, Editable
Hide when previewed for reading, opened for reading, printed

FIELD Details_History:
Rich Text, Computed
never hide

Sub Queryclose(Source As Notesuidocument, Continue As Variant)
 On Error Goto Oops

 Dim session As New NotesSession
 Dim doc As NotesDocument
  Set doc = session.CurrentDatabase.GetDocumentByUNID(Source.Document.UniversalID)
 Dim vDetails As Variant
  Set vDetails = doc.GetFirstItem("Details")
 Dim vHistory As Variant
  Set vHistory = doc.GetFirstItem("Details_History")

  If (vDetails.Type = RICHTEXT And vHistory.Type = RICHTEXT) Then
    Call vHistory.AppendText(Format$(Now, "mm/dd/yy hh:nn AM/PM") & " by " & session.CommonUserName & ":  ")
    Call vHistory.AppendRTItem(vDetails)
    Call vHistory.AddNewLine(2)
    Call vDetails.Remove
    Call doc.Save(True, False)
  End If

TheEnd:
  Continue = True
Exit Sub

Oops:
  Resume TheEnd
End Sub
