Remarks

The IProvideClassInfo2 interface extends IProvideClassInfo by adding the GetGUID method. This method allows a client to retrieve an object's outgoing interface IID for its default event set. Class IProvideClassInfo2Impl provides a default implementation of the IProvideClassInfo and IProvideClassInfo2 methods.

IProvideClassInfo2Impl contains a static member of type CComTypeInfoHolder that manages the type information for the coclass.
