Introduction

Remarques

Déclaration et utilisation de l'API

Déclaration d'une procédure DLL pour fonctionner avec différentes versions de 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

La déclaration ci-dessus indique à VBA comment appeler la fonction "Sleep" définie dans le fichier Kernel32.dll

Win64 et Win32 sont des constantes prédéfinies utilisées pour la compilation conditionnelle

Constantes prédéfinies

Certaines constantes de compilation sont déjà prédéfinies. Les versions existantes dépendront de la qualité de la version bureautique dans laquelle vous exécutez VBA. Notez que Vba7 a été introduit avec Office 2010 pour prendre en charge les versions 64 bits d'Office.

Ces constantes font référence à la version d'Office, pas à la version Windows. Par exemple, Win32 = TRUE dans Office 32 bits, même si le système d'exploitation est une version 64 bits de Windows.

La principale différence lors de la déclaration des API se situe entre les versions Office 32 bits et 64 bits qui ont introduit de nouveaux types de paramètres (voir la section Remarques pour plus de détails).

Remarques:

• Les déclarations sont placées en haut du module, et en dehors de tout Subs ou Fonctions
• Les procédures déclarées dans les modules standard sont publiques par défaut
• Pour déclarer une procédure privée à un module, faites précéder la déclaration par le mot-clé Private
• Les procédures DLL déclarées dans tout autre type de module sont privées à ce module

Exemple simple pour l'appel de l'API Sleep:

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

Il est recommandé de créer un module API dédié pour fournir un accès facile aux fonctions système à partir des wrappers VBA (sous-systèmes VBA normaux ou fonctions) qui encapsulent les détails nécessaires à l'appel système, tels que les paramètres utilisés dans les bibliothèques et l'initialisation de ces paramètres.

Le module peut contenir toutes les déclarations et dépendances:

• Signatures de méthode et structures de données requises
• Les wrappers qui effectuent la validation des entrées et vérifient que tous les paramètres sont transmis comme prévu

Pour déclarer une procédure DLL, ajoutez une instruction Declare à la section Déclarations de la fenêtre de code.

Si la procédure renvoie une valeur, déclarez-la comme fonction :

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

Si une procédure ne renvoie pas de valeur, déclarez-la en tant que Sub :

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

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

Il convient également de noter que la plupart des appels non valides à l’API entraîneront un plantage d’Excel , voire des fichiers de données corrompus.

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

Office 2011 pour 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

Les exemples ci-dessous (API Windows - Module dédié (1 et 2)) affichent un module API qui inclut des déclarations communes pour Win64 et Win32

Office 2016 pour Mac est en bac à sable

Contrairement aux autres versions des applications Office prenant en charge VBA, les applications Office 2016 pour Mac sont en mode bac à sable.

Sandboxing empêche les applications d'accéder aux ressources en dehors du conteneur d'applications. Cela affecte tous les compléments ou macros qui impliquent l'accès aux fichiers ou la communication entre les processus. Vous pouvez minimiser les effets du sandboxing en utilisant les nouvelles commandes décrites dans la section suivante. Nouvelles commandes VBA pour Office 2016 pour Mac

Les commandes VBA suivantes sont nouvelles et uniques à Office 2016 pour Mac.
