GUIRegisterMsg Without a GUI?

[seadoggie01]

I'm making a script to copy files off an SD card for me. I found some code on the forums and it works great, but only if I create a GUI to go with it. It's not a big deal, I just create a tiny window, show it, register my command, hide it, and never show it again. It just seems like a weird way to do things. I was hoping to just use a tray icon and leave GUIs out of it. So...

Does GUIRegisterMsg() have to be used with a GUI?

I mean, it's in the name, but nothing else I've found (documentation-wise) seems to suggest that. I've noticed that nobody uses it without one, but not many people use GUIRegisterMsg without any sort of GUI. If so, can I register it to the AutoIt hidden window and consume the event in my script, or am I better off with a tiny unused window?

 

Edit: And of course, thank you for taking the time to read this and help a newbie out I've learned a lot from these forums and it's been less than a month. Also included code if anyone wants.

You could always hide your GUI

EDIT: 
It depends from which havent is registered.
Show us the code

I'm just wondering if the GUI is necessary

Post the code, so we can see if you can do it or not

Hello. Just create the GUI with GUICreate but dont call the show function "GUISetState(@SW_SHOW, $hGUI)"
