<section begin="short"/>Provides support for late-bound interface calls (Automation functionality).<section end="short"/>

Use [[System.Win.ObjComAuto.TObjectDispatch|TObjectDispatch]] to obtain the [[System.IDispatch|IDispatch]] interface of an Automation object (or server). Use [[System.IDispatch|IDispatch]] to invoke a particular method by its dispatch identifier (dispid).

To use [[System.Win.ObjComAuto.TObjectDispatch|TObjectDispatch]], you have to define a class that will act as an Automation server. A [[System.Win.ObjComAuto.TObjectDispatch|TObjectDispatch]] instance is associated with a [[System.TObject|TObject]] instance&mdash;the Automation server.

<blockquote>'''Note:''' Make sure that the compiler generates extended RTTI for the Automation server class. See the [[rad_en:METHODINFO directive (Delphi)|$METHODINFO ON directive]].</blockquote>
