3.3.3.0.1 Message loop
To receive events, it is necessary to have a message loop in the thread that owns the object that is receiving the events. All events are dispatched through a Windows message queue created during COM initialization. Without a message loop, the event objects implemented by LuaCOM , will never receive method calls from the COM objects they are registered with. Out-of-process COM servers implemented with LuaCOM also need a message loop to be able to service method calls (one is provided by callingluacom.DetectAutomation).
