Добрый день! Как определить является ли поле типа RichText пустым, причем не важно что в нем текст или файл?? При условии, что документ новый на редактировании, ни разу не сохранялся.

Код:
If Isempty(RTitem.EmbeddedObjects) And Fulltrim(RTitem.GetFormattedText( False, 0)) = "" Then
'..........
End If

Код:
Function IsEmptyRTItem(rtitem As NotesRichTexItem) As Boolean
Dim rtnav As NotesRichTextNavigator
Set rtnav = rtitem.CreateNavigator()
If rtnav.FindFirstElement(1) Then
Elseif rtnav.FindFirstElement(3) Then
Elseif rtnav.FindFirstElement(4) Then
Elseif rtnav.FindFirstElement(5) Then
Elseif rtnav.FindFirstElement(6) Then
Elseif rtnav.FindFirstElement(7) Then
Elseif rtnav.FindFirstElement(8) Then
Elseif rtnav.FindFirstElement(9) Then
Else
IsEmptyRTItem = True
Exit Function
End If
IsEmptyRTItem = False
End Function
Вставленные картинки не определяет, для этого придётся использовать DXL

Перед проверкой uidoc.Refresh(True)

когда-то использовал такой код

Omh

Начиная с 6-ки это работает.
Может ты конечно знаешь что-то джедайское, что бы это перестало работать, но я не встречался.
У тебя были плохие примеры?
