3/26/2014

This interface allows ITypeInfo to cast to an ITypeInfo2 in performance-sensitive cases. An ITypeInfo can be cast to an ITypeInfo2 instead of using the calls IUnknown::QueryInterface and IUnknown::Release. This casting procedure is not compatible with Windows 95 or Windows NT version 3.51.

Methods

The following table shows the methods for this interface in the order that the compiler calls the methods. Like all COM interfaces, this interface inherits the methods for the IUnknown interface. This interface also inherits the methods for the ITypeInfo interface.
