Since GME COM objects are apartment-threaded, you cannot directly access GMEApplication or the model from a different thread. I'd recommend one of two approaches: 1. when your addon or interpreter starts, create a hidden window, then your thread can Post/SendMessage to that hidden window and do processing on the main thread; 2. use CoMarshalInterThreadInterfaceInStream to pass COM interfaces to your thread. Of course, both of these approaches require that GME is pumping messages (e.g. not running an interpreter).<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>When GME is pumping messages, it is typically not in a model transaction.
