Can’t be done natively with VBA. VBA is built in a single-threaded apartment. The only way to get multiple threads is to build a DLL in something other than VBA that has a COM interface and call it from VBA. INFO: Descriptions and Workings of OLE Threading Models
Concurrent and parallel are effectively the same principle as you correctly surmise, both are related to tasks being executed simultaneously although I would say that parallel tasks should be truly multitasking, executed “at the same time” whereas concurrent could mean that the tasks are sharing the execution thread while still appearing to be executing in … Read more
