IADsClass Property Methods

Applies to: desktop apps only

The property methods of the IADsClass interface get or set the following properties. For more information, see Interface Property Methods.

Properties

Abstract

Boolean value that indicates if this class is Abstract or non-abstract. When TRUE, this class is an Abstract class and cannot be directly instantiated in the directory service. Abstract classes can only be used as super classes.
Access type: Read/write
Scripting data type: BOOLEAN
Copy // C++ method syntax HRESULT get_Abstract( [out] BOOLEAN* pbAbstract ); HRESULT put_Abstract( [in] BOOLEAN bAbstract );

AuxDerivedFrom

Array of ADsPath strings that indicate the super Auxiliary classes this class derives from.
Access type: Read/write
Scripting data type: VARIANT
Copy // C++ method syntax HRESULT get_AuxDerivedFrom( [out] VARIANT* pvAuxDerivedFrom ); HRESULT put_AuxDerivedFrom( [in] VARIANT vAuxDerivedFrom );

Auxiliary

Boolean value that indicates whether or not this class is Auxiliary. When TRUE, this class is an Auxiliary class and cannot be directly instantiated in the directory service. Auxiliary classes can only be used as super classes of other Auxiliary classes or as a source of additional properties on structural classes.
Access type: Read/write
Scripting data type: BOOLEAN
Copy // C++ method syntax HRESULT get_Auxiliary( [out] BOOLEAN* pbAuxiliary ); HRESULT put_Auxiliary( [in] BOOLEAN bAuxiliary );

CLSID

Optional provider-specific CLSID identifying the COM object that implements this class.
Access type: Read/write
Scripting data type: BSTR
Copy // C++ method syntax HRESULT get_CLSID( [out] BSTR* pbstrCLSID ); HRESULT put_CLSID( [in] BSTR bstrCLSID );

Container

Boolean value that indicates if this class can be a container of other object classes. If this value is TRUE, you can call the get_Container method to get an array of the object classes that this class can contain.
Access type: Read/write
Scripting data type: BOOLEAN
Copy // C++ method syntax HRESULT get_Container( [out] BOOLEAN* pbContainer ); HRESULT put_Container( [in] BOOLEAN bContainer );

Containment

A BSTR array in which each element is the name of an object class that this class can contain.
Access type: Read/write
Scripting data type: VARIANT
Copy // C++ method syntax HRESULT get_Containment( [out] VARIANT* pvContainment ); HRESULT put_Containment( [in] VARIANT vContainment );

DerivedFrom

Array of ADsPath strings that indicate which classes this class was derived from.
Access type: Read/write
Scripting data type: VARIANT
Copy // C++ method syntax HRESULT get_DerivedFrom( [out] VARIANT* pvDerivedFrom ); HRESULT put_DerivedFrom( [in] VARIANT vDerivedFrom );

HelpFileContext

Context ID inside HelpFileName where specific information for this class can be found.
Access type: Read/write
Scripting data type: long
Copy // C++ method syntax HRESULT get_HelpFileContext( [out] long* plHelpContext ); HRESULT put_HelpFileContext( [in] long lHelpContext );

HelpFileName

Name of a help file that contains more information about objects of this class.
Access type: Read/write
Scripting data type: BSTR
Copy // C++ method syntax HRESULT get_HelpFileName( [out] BSTR* pbstrHelpFileName ); HRESULT put_HelpFileName( [in] BSTR bstrHelpFileName );

MandatoryProperties

SAFEARRAY of VARIANTs that lists the properties that must be set for this class to be written to storage. If the class only contains one property, then get_MandatoryProperties will return a BSTR.
Access type: Read/write
Scripting data type: VARIANT
Copy // C++ method syntax HRESULT get_MandatoryProperties( [out] VARIANT* pvarMandatoryProperties ); HRESULT put_MandatoryProperties( [in] VARIANT varMandatoryProperties );

NamingProperties

SAFEARRAY of BSTRs that lists the properties used to name attributes of this schema class. For example, in NDS, "CN" and "OU" are naming properties.
Access type: Read/write
Scripting data type: VARIANT
Copy // C++ method syntax HRESULT get_NamingProperties( [out] VARIANT* pvarNamingProperties ); HRESULT put_NamingProperties( [in] VARIANT varNamingProperties );

OID

Provider-specific Object Identifier that defines this class. This is provided to allow schema extension, using Active Directory, in directory services that require provider-specific OIDs for classes.
Access type: Read/write
Scripting data type: BSTR
Copy // C++ method syntax HRESULT get_OID( [out] BSTR* pbstrOID ); HRESULT put_OID( [in] BSTR bstrOID );

OptionalProperties

SAFEARRAY of VARIANTs that lists the optional properties for this schema class. If the class only contains one property, then get_OptionalProperties will return a BSTR.
Access type: Read/write
Scripting data type: VARIANT
Copy // C++ method syntax HRESULT get_OptionalProperties( [out] VARIANT* pvarOptionalProperties ); HRESULT put_OptionalProperties( [in] VARIANT varOptionalProperties );

PossibleSuperiors

Array of ADsPath strings that indicate the schema classes that can contain instances of this class.
Access type: Read/write
Scripting data type: VARIANT
Copy // C++ method syntax HRESULT get_PossibleSuperiors( [out] VARIANT* pvSuperiors ); HRESULT put_PossibleSuperiors( [in] VARIANT vSuperiors );

PrimaryInterface

Optional provider-specific identifier GUID that associates an interface to objects of this schema class. For example, the "User" class that supports IADsUser and PrimaryInterface is identified by IID_IADsUser. This must be in the standard string format of a GUID, as defined by COM. This GUID is the value that appears in the IADs::get_GUID property in instances of this class for providers that implement this property. Identifying a schema class by IID of the class code's primary interface enables the use of QueryInterface at run time to determine whether an object is of the desired class.
Access type: Read-only
Scripting data type: BSTR
Copy // C++ method syntax HRESULT get_PrimaryInterface( [out] BSTR* pbstrGUID );

Examples

The following code example shows how to use the IADsClass interface to determine if an object can be a container and, if so, lists the names of any contained objects.

Copy

Dim ads As IADs
Dim cls As IADsClass

On Error GoTo Cleanup

Set ads = GetObject("WinNT://myComputer,computer")
Set cls = GetObject(ads.Schema)
if cls.Container = True Then
    MsgBox "This object contains the following children:"
    For Each o In cls.Containment
        MsgBox o
    Next
End If

Cleanup:
    If (Err.Number<>0) Then
        MsgBox("An error has occurred. " & Err.Number)
    End If
    Set ads = Nothing
    Set cls = Nothing
