Господа, здравствуйте! Вопрос предельно прост: как получить документ который выбран в текущем представлении. Документ не открыт, а на нём просто стоит курсор, и, например, при нажатии кнопочки с этим документом что-то делается. Как это возможно?

1 способ
Код:
	caretNoteID$ = notesUIView.CaretNoteID
Set notesDocument = notesDatabase.GetDocumentByID( noteID$ )
2 способ
Код:
Set notesDocument = notesSession.DocumentContext
3 способ
Код:
	Set notesDocumentCollection = notesDatabase.UnprocessedDocuments
Set notesDocument = notesDocumentCollection.GetFirstDocument
Последний способ худший в данном случае, так как если выделен галочкой один документ, а курсор на другом документе, то мы получим документ, выделенный галочкой, а не документ позиции курсора.

а что знатоки скажут про вьюху в диалоговом боксе, можно ли там получить выделенный док7
поясню - пишем диалог, туда кладем вьюху и лист бокс. можно ли спозиционировать во вьюхе маркер и получить данные в лист бокс7
я пытася, так и не получилось.

Либо это надо делать в 2 этапа:
1) выбрать документ с помощью @PickList
2) рассчитать и вывести ListBox
Либо прямо на диалоговой форме сделать кнопку, вызывающую агент. Данный агент изменит какое-нибудь поле (документа или ui-документа), потом пересчитает все формулы и условное скрытие. Вот тогда и обновится ваш ListBox.
Код:
	Dim ws As New NotesUIWorkspace
Dim sess As New NotesSession
Dim db As NotesDatabase
Dim doc As NotesDocument, caret As NotesDocument, uid As NotesUIDocument
Dim uiv As NotesUIView
Dim s_id$
Set uiv = ws.CurrentView
Set db = sess.CurrentDatabase
Set uid = ws.CurrentDocument
Set doc = uid.Document
If doc Is Nothing Then ... 
s_id = uiv.CaretNoteID
If s_id = "" then ...
Set caret = db.GetDocumentByID(s_id)		' Документ курсора во встроенном виде
If caret Is Nothing Then ...
Как видите, первый вариант попроще будет :)


ЗЫ: Если документ doc не записан, то получить caret можно будет, если приведенный код повесить на Action в самой встроенной вьюхе, ну и отобразить панель действий, естественно (годится для 6 и выше)

хе-хе, пора идти на курсы правильного излагания своих вопросов и понимания ответов

я хотел сделать что-то типа стандартного лотусового диалога "Select adresses"... ну, это когда вы в письме тискаете на кнопочку "Кому" и там встроенная вьюшка и лист боксик (ну, или что-то похожее на него).

Вариант с агентом дает такую возможность при соответствующем подходе.

Просто я так поняла, что этого не достаточно, а нужно еще список пересчитывать на основной форме по данным документа курсора.
К сожалению, я не знаю способа, каким можно поймать изменение положения такого курсора. Так что проще и быстрее все-таки вариант первый :)

А если что придумаете получше, расскажите - интересно

Class SelectedDocsList

%REM
The SelectedDocsList class provides a way to programmatically access
the list of selected docs in a view that's currently open in the Notes client
(open in a tab, a frame, or as an embedded view), without relying on an
agent to be running against "Selected docs" in a view.

Because we're calling the C-API, you'll also need to declare several API
functions in the Declarations section of the agent or script library that
holds this class. If you got this class without the related API declarations,
please see the original version of this code at http://www.nsftools.com

Here's an example of getting the selected docs in a view:

A few things to note about this class:

1. This will ONLY work when running on a local Notes client, while the
client is open. If you try to run it on your server, you may crash it.

2. The docs are NOT returned in the same order they are seen in the view.
They seem to be in order of creation date, starting from the earliest (although
this is just what I've seen in preliminary testing, and might not be true all the time).

3. If the view that you're pointing to is not currently open in the client anywhere,
this class should just return a GetCount value of 0 (not an error or a crash).

4. If you're using this in an agent, you do NOT need to have the agent set
to run against "Selected Docs". However, it's very possible that the agent
has to be run by the user (as opposed to a background agent) -- I haven't
done any testing on background/scheduled agents, but this class is really
meant to be run in the front-end.

5. One way that I used this class was to get the docs that were selected
in a view that was embedded on a Form. Doing this, I could allow actions
and buttons on the Form to access the selected docs in the embedded view
by simply passing a proper handle to the view that was embedded. In other
words, if the embedded view is called "SpecialDocs", you simply create
an instance of the class using db.GetView("SpecialDocs") in the constructor.
You can do this when the form is opened and keep it in memory as a global
object if you want. Just remember to call the RefreshList method before you
try to get the selected docs at any given time, to make sure you have the
current list. However....

6. This does NOT return the proper document list for embedded views that
have "Show Single Category" set.

You can use this code in any way you want, as long as you don't hold me
liable for anything, and you don't pretend you wrote it yourself.
