Mimic behavior of a loaded form?

Does anyone know how to make a standard VB EXE (Unattended execution enabled) continue to run without loading a form. An App that starts in Sub Main and continues running as if a form is loaded even though there is no loaded form. I cant have an endless loop with a doevents or anything like that. it just needs to set there running without taxing the processor, like a VB app would behave if all it did was Show a form. . .

That would be a WINDOWS SERVICE. You can create one, and have it load with the OS
