9 GUID

• Short for Globally Unique Identifier

• Used by the Windows registry to identify COM DLLs

• Knowing where to look in the registry and having the correct GUID yields a lot information about a COM object (i.e., information in the type library, its physical location, etc.)

10 InterfaceType

• Interfaces add a plug and play like architecture into your applications. Interfaces help define a contract between your application and other objects. It indicates what sort of methods, properties and events are exposed by the object.


11 ComInterfaceType

• Identifies how to expose an interface to COM. • InterfaceIsIDispatch - Indicates an interface is exposed to COM as a

dispinterface, which enables late binding only.

• InterfaceIsDual is the default value.

• InterfaceIsIUnknown.

12 Delegate

• A delegate is a type that represents references to methods with a particular parameter list and return type.

• Delegates are used to pass methods as arguments to other methods.

• Event handlers are nothing more than methods that are invoked through delegates.
