I think you could make a form, and set its visibility to False. As long
as you don't stall for input, as a messagebox would, it should not hang.
Don't forget, if you are starting as a console app (as services
typically should be) you are going to ALSO need a message pump. Careful
about not doing other processing on the pump's thread that will stall
message delivery. I would use a dedicated thread for this. Myself I
would simply call Win32 API to create the invisible window. I have made
services in VB6 in this way. Also, don't forget to send messages to
close your window, and be sure to process them via the pump when you
want the service to exit. I think you could use the pump built into
application.
