ITypeInfo

ITypeInfo is a COM (Component Object Model) interface that provides information about a type, such as a COM interface, a class, or a structure. It is part of the COM type library system, which is used to describe the types and methods of COM objects. The ITypeInfo interface is typically obtained from an ITypeLib interface, which represents a type library.

The ITypeInfo interface provides methods to retrieve information about the type, such as its name, GUID, and version. It also provides methods to retrieve information about the type's members, such as methods, properties, and events. The ITypeInfo interface can be used to dynamically create instances of the type, to invoke methods on the type, and to retrieve information about the type's members.

The ITypeInfo interface is used by various COM technologies, such as Automation, ActiveX, and OLE. It is also used by tools and frameworks that work with COM, such as Visual Studio and the .NET Framework. The ITypeInfo interface is defined in the OLE Automation specification and is part of the COM library in Windows.

In summary, ITypeInfo is a COM interface that provides information about a type, such as a COM interface, a class, or a structure. It is part of the COM type library system and is used by various COM technologies and tools. The ITypeInfo interface provides methods to retrieve information about the type and its members, and to dynamically create instances of the type and invoke methods on it.
