Window messages in windows application with no window

Question

I have an application that I want to run in the background with no visible windows or consoles. To accomplish this, I create a windows application but I do not create a window.

Answer 1

A couple of options:

1. Create a window, but don't set the WS_VISIBLE flag.
2. Create a message-only window.

The difference would be that invisible windows receive broadcast messages, while message-only windows do not.
