Deklaracja API i użycie

Deklarowanie procedury DLL do pracy z różnymi wersjami VBA:

Option Explicit

#If Win64 Then

    Private Declare PtrSafe Sub xLib "Kernel32" Alias "Sleep" (ByVal dwMilliseconds As Long)

#ElseIf Win32 Then

    Private Declare Sub apiSleep Lib "Kernel32" Alias "Sleep" (ByVal dwMilliseconds As Long)

#End If

Powyższa deklaracja mówi VBA, jak wywołać funkcję „Uśpienie” zdefiniowaną w pliku Kernel32.dll

Win64 i Win32 to predefiniowane stałe używane do kompilacji warunkowej

Predefiniowane stałe

Niektóre stałe kompilacji są już wstępnie zdefiniowane. Te, które istnieją, będą zależeć od bitowej wersji pakietu Office, w której używasz VBA. Pamiętaj, że Vba7 został wprowadzony wraz z pakietem Office 2010 do obsługi 64-bitowych wersji pakietu Office.

Te stałe odnoszą się do wersji pakietu Office, a nie wersji systemu Windows. Na przykład Win32 = PRAWDA w 32-bitowym pakiecie Office, nawet jeśli system operacyjny jest 64-bitową wersją systemu Windows.

Główną różnicą przy deklarowaniu interfejsów API jest między 32-bitową a 64-bitową wersją pakietu Office, która wprowadziła nowe typy parametrów (więcej szczegółów znajduje się w sekcji Uwagi)

Uwagi:

• Deklaracje są umieszczane na górze modułu i poza wszelkimi funkcjami dodatkowymi lub funkcjami
• Procedury zadeklarowane w standardowych modułach są domyślnie publiczne
• Aby zadeklarować procedurę jako prywatną dla modułu, należy poprzedzić deklarację słowem kluczowym Private
• Procedury DLL zadeklarowane w dowolnym innym typie modułu są prywatne dla tego modułu

Prosty przykład wywołania funkcji Sleep API:

Public Sub TestPause()

    Dim start As Double

    start = Timer

    Sleep 9000      'Pause execution for 9 seconds

    Debug.Print "Paused for " & Format(Timer - start, "#,###.000") & " seconds"

    'Immediate window result: Paused for 9.000 seconds

End Sub

Zaleca się utworzenie dedykowanego modułu API zapewniającego łatwy dostęp do funkcji systemowych z opakowań VBA - normalne VBA Subs lub Funkcje, które zawierają szczegóły potrzebne do rzeczywistego wywołania systemowego, takie jak parametry używane w bibliotekach i inicjalizacja tych parametrów

Moduł może zawierać wszystkie deklaracje i zależności:

• Podpisy metod i wymagane struktury danych
• Opakowania, które wykonują sprawdzanie poprawności danych wejściowych i zapewniają przekazanie wszystkich parametrów zgodnie z oczekiwaniami

Aby zadeklarować procedurę DLL, dodaj Declare oświadczenie do sekcji deklaracji okna kodu.

Jeśli procedura zwraca wartość, zadeklaruj ją jako funkcję :

Declare Function publicname Lib "libname" [Alias "alias"] [([[ByVal] variable [As type] [,[ByVal] variable [As type]]...])] As Type

Jeśli procedura nie zwraca wartości, zadeklaruj ją jako Sub :

Declare Sub publicname Lib "libname" [Alias "alias"] [([[ByVal] variable [As type] [,[ByVal] variable [As type]]...])]

• !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!

Należy również zauważyć, że większość niepoprawnych wywołań interfejsu API spowoduje awarię programu Excel i prawdopodobnie spowoduje uszkodzenie plików danych

• !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!

Office 2011 dla komputerów Mac

Private Declare Function system Lib "libc.dylib" (ByVal command As String) As Long

Sub RunSafari()
    Dim result As Long
    result = system("open -a Safari --args http://www.google.com")
    Debug.Print Str(result)
End Sub

Poniższe przykłady (Windows API - moduł dedykowany (1 i 2)) pokazują moduł API, który zawiera wspólne deklaracje dla Win64 i Win32

Interfejsy API dla komputerów Mac

Microsoft oficjalnie nie obsługuje interfejsów API, ale przy niektórych badaniach można znaleźć więcej deklaracji online

Pakiet Office 2016 dla komputerów Mac jest w trybie piaskownicy

W przeciwieństwie do innych wersji aplikacji pakietu Office obsługujących język VBA, aplikacje pakietu Office 2016 dla komputerów Mac są w trybie piaskownicy.

Piaskownica ogranicza dostęp aplikacji do zasobów poza kontenerem aplikacji. Wpływa to na wszelkie dodatki lub makra, które wymagają dostępu do plików lub komunikacji między procesami. Możesz zminimalizować efekty piaskownicy, używając nowych poleceń opisanych w poniższej sekcji. Nowe polecenia VBA dla pakietu Office 2016 dla komputerów Mac

Następujące polecenia VBA są nowe i unikalne dla pakietu Office 2016 dla komputerów Mac.
