保存文档前判断RTF域是否是空值

保存文档前判断RTF域是否是空值
RTF域在文档没有保存前，是不能通过script判断的，因此需要以下程序识别是否是空值。
你可以使用下面这个函数来判断,在QuerySave中添加如下代码:

flag = IsRTFNull("你的RTF域名")
If flag = True Then
    Messagebox "请填写内容"
    Continue = False
End If
Function IsRTFNull(rtfield As String) As Integer
    On Error Goto Errhandle
    Dim workspace As New NotesUIWorkspace
    Dim uidoc As NotesUIDocument
    Set uidoc = workspace.CurrentDocument
    currentfield = uidoc.CurrentField
    Call uidoc.GotoField(rtfield)
    Call uidoc.SelectAll
    Call uidoc.DeselectAll
    If currentfield <> "" Then
        Call uidoc.GotoField(currentfield)
    End If
    IsRTFNull = False
Exit Function
Errhandle:
    Select Case Err
    Case 4407
'the DeselectAll line generated an error message, indicating that the rich text field does not contain anything
        If currentfield <> "" Then
            Call uidoc.GotoField(currentfield)
        End If
        IsRTFNull = True
        Exit Function
    Case Else
'For any other error, force the same error to cause LotusScript to do the error handling
        Error Err
    End Select
End Function
