Use GetComponentNames to call the procedure specified by the Proc parameter for every component that can be assigned a property that matches the TypeData parameter. For each component, Proc is called with its S parameter set to the name of the component. This parameter can be used to obtain a reference to the component by calling the GetComponent method. 

Note: GetComponentNames calls Proc for components in global components that can be defined using TDesignerEvents.OnGetGlobalComponents event handler.
