[Windows] Processing system messages

My app works without GUI.
But sometimes I need to process some system events, for example, WM_QUERYENDSESSION:
Code: Select all
Procedure WinCallback(hWnd, uMsg, wParam, lParam)
If uMsg = #WM_QUERYENDSESSION
...Some code...
EndIf
ProcedureReturn #PB_ProcessPureBasicEvents
EndProcedure
But for processing system events, I need to create invisible window and process them in window main loop WaitWindowEvent()
Can I make processing of events without invisible window?

You need a window. It is not possible without window.

Yep, just make the window visible.
(Sorry, couldn't resist).

What you want is a message-only window. You can create one easily by creating a PureBasic window and applying SetParent_() to it specifying #HWND_MESSAGE for the parent window handle or with CreateWindowEx if you prefer.

netmaestro, from your link:
[...]and does not receive broadcast messages.[...]
I'm not sure if it fit for me.
