CComAggObject Implements
IUnknown
for an aggregated object.CComObject Implements
IUnknown
for a nonaggregated object.CComPolyObject Implements
IUnknown
for aggregated and nonaggregated objects. UsingCComPolyObject
avoids having bothCComAggObject
andCComObject
in your module. A singleCComPolyObject
object handles both aggregated and nonaggregated cases.CComObjectNoLock Implements
IUnknown
for a nonaggregated object, without modifying the module lock count.CComTearOffObject Implements
IUnknown
for a tear-off interface.CComCachedTearOffObject Implements
IUnknown
for a "cached" tear-off interface.CComContainedObject Implements
IUnknown
for the inner object of an aggregation or a tear-off interface.CComObjectGlobal Manages a reference count on the module to ensure your object won't be deleted.
