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 Microsoft 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.

This method returns the TYPEFLAGS quickly, without doing any allocations.

ITypeInfo2::GetFuncIndexOfMemId

This method binds to a specific member based on a known dispatch identifier (DISPID).

ITypeInfo2::GetVarIndexOfMemId

This method binds to a specific member based on a known dispatch identifier (DISPID).
