Hallo alle zusammen,
es ist mal wieder soweit. Ich habe für Excel ein Modul mit API-Funktionen zum Ändern der Druckerschächte.
Meine Frage ist nun, wie lässt sich das in Notes umsetzen?
Hier erst mal der Code:
Option Explicit

' ==================================================================
' SetPrinterDuplex
'
' Programmatically set the Duplex flag for the specified printer
' driver's default properties.
'
' Returns: True on success, False on error. (An error will also
' display a message box. This is done for informational value
' only. You should modify the code to support better error
' handling in your production application.)
'
' Parameters:
' sPrinterName - The name of the printer to be used.
'
' nDuplexSetting - One of the following standard settings:
' 1 = None
' 2 = Duplex on long edge (book)
' 3 = Duplex on short edge (legal)

End Function
Sub test()
SetPrinterDuplex "HP LaserJet 4200 Schacht 2", 1
End Sub
Wo "Sub Test" und "Public Function SetPrinterDuplex" sowie die Konstanten hingehören, ist mir klar. Was mir nicht genau klar ist, wo die eigentlichen API-Funktionen beispielsweise in einem Agenten eingefügt werden müssen.
Bei der Forum Suche hat er mir zum Thema "API" oder "API in Notes" viele Beiträge angezeigt, von denen die wenigsten beim schnellen durchklicken wirklich etwas damit zu tun hatten.
