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
Public Type PRINTER_DEFAULTS
pDatatype As Long
pDevmode As Long
DesiredAccess As Long
End Type
Public Type PRINTER_INFO_2
pServerName As Long
pPrinterName As Long
pShareName As Long
pPortName As Long
pDriverName As Long
pComment As Long
pLocation As Long
pDevmode As Long ' Pointer to DEVMODE
pSepFile As Long
pPrintProcessor As Long
pDatatype As Long
pParameters As Long
pSecurityDescriptor As Long ' Pointer to SECURITY_DESCRIPTOR
Attributes As Long
Priority As Long
DefaultPriority As Long
StartTime As Long
UntilTime As Long
Status As Long
cJobs As Long
AveragePPM As Long
End Type
Public Type DEVMODE
dmDeviceName As String * 32
dmSpecVersion As Integer
dmDriverVersion As Integer
dmSize As Integer
dmDriverExtra As Integer
dmFields As Long
dmOrientation As Integer
dmPaperSize As Integer
dmPaperLength As Integer
dmPaperWidth As Integer
dmScale As Integer
dmCopies As Integer
dmDefaultSource As Integer
dmPrintQuality As Integer
dmColor As Integer
dmDuplex As Integer
dmYResolution As Integer
dmTTOption As Integer
dmCollate As Integer
dmFormName As String * 32
dmUnusedPadding As Integer
dmBitsPerPel As Integer
dmPelsWidth As Long
dmPelsHeight As Long
dmDisplayFlags As Long
dmDisplayFrequency As Long
dmICMMethod As Long
dmICMIntent As Long
dmMediaType As Long
dmDitherType As Long

dmReserved2 As Long
End Type

' ==================================================================
' 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)

cleanup:
If (hPrinter <> 0) Then Call ClosePrinter(hPrinter)
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.
