02/22/2024

The ObjectId property retrieves the object identifier (OID) for the attribute.

This property is read-only.

Syntax

HRESULT get_ObjectId(
  IObjectId **ppValue
);

Parameters

ppValue

Return value

None

Remarks

You can initialize an IObjectId object by calling InitializeFromName. This method initializes the object by using a value from the CERTENROLL_OBJECTID enumeration. The enumeration value is associated with an ASN.1 object identifier. For example, the value XCN_OID_COUNTRY_NAME is associated with a string containing 2.5.4.6. This is the dotted decimal representation of the joint-iso-itu-t(2)ds(5)attributeType(4)countryName(6) object identifier.
