automation object member not found
BKreplin:
Ja, ich habe mit dem Step by Step Debugger festgestellt, dass ExtractFile den Fehler hervorruft.
Glombi:
--- Zitat von: kennwort am 28.07.05 - 17:25:27 ---Automation Object Member not found ist eine OLE Fehlermeldung soweit ich weiss. Keine Notes Fehlermeldung.
--- Ende Zitat ---
Ja klar, aber dann verstehe ich den Codeschnipsel nicht, den er oben angeführt hat.
Diese Meldung kenne ich auch nur im Zusammenhang mit OLE und COM Objekten.
Aber wenn wir hier nur ein paar Zeilen bekommen, können wir lang und breit spekulieren.
Andreas
flaite:
Ich find spekulieren eigentlich auch ganz interessant.
--- Zitat von: BKreplin am 28.07.05 - 17:18:50 ---Zur Frage COM oder OLE kann ich sagen, dass die bewusste Session mit
Set Me.session = New NotesSession
Set Me.workspace = New NotesUIWorkspace
Set Me.uidoc = workspace.CurrentDocument
eingerichtet wird.
Das spricht für OLE.
--- Ende Zitat ---
Nö. Das spricht wiederum für com. Wo liegt dieser Code? In einem NotesAgenten/Scriptlibrary oder ausserhalb von Notes?
BKreplin:
1. Es geht um ein Attachment
