Exemple de code pour l’utilisation d’interfaces IADsProperty pour accéder au cache de propriétés

L’exemple de code suivant montre comment utiliser les interfaces IADsPropertyList, IADsPropertyEntry et IADsPropertyValue avec C++ et ADSI.

HRESULT hr;
BSTR    bstr;
VARIANT var;
IDispatch *pDispatch;
IADsPropertyList *pPropList;

    } 
}

L’exemple de code suivant montre comment utiliser les interfaces IADsPropertyList, IADsPropertyEntry et IADsPropertyValue à l’aide de Visual Basic et d’ADSI.

Dim propList As IADsPropertyList
Dim propEntry As IADsPropertyEntry
Dim propVal As IADsPropertyValue
Dim count As Long
 
Set propList = GetObject("LDAP://dc01/DC=Fabrikam,DC=com")
 
propList.GetInfo
count = propList.PropertyCount
Debug.Print "No of Property Found: " & count
 
For i = 0 To count - 1
    ' Each item in the property list has a property entry.
    Set propEntry = propList.Item(i)
    Debug.Print propEntry.Name
    Debug.Print propEntry.ADsType
    
    ' Each value in property entry has property values.
    For Each v In propEntry.Values
        Set propVal = v
        Debug.Print propVal.ADsType
    Next
