How to detect Windows hibernation mode?

[Marc56us]

WM_QUERYENDSESSION detects the end of the session, but is it possible to detect the Windows hibernation ?

The reason: I would like to be able to stop the web radio and/or MP3 play of my programs when the user clicks on Hibernation mode (Hibernation mode launch by Windows or by command: rundll32.exe powrprof.dll,SetSuspendState 1,0,1) Otherwise, the music will immediately resume from deep sleep.

Code: Select all

EnableExplicit

Procedure WinCallback(hWnd, uMsg, wParam, lParam) 
  
  Select uMsg 
    Case #WM_POWERBROADCAST 
      Select wParam
        Case #PBT_APMSUSPEND
          Debug "PC now goes into hibernation."
          
      EndSelect
  EndSelect 
  
  ProcedureReturn #PB_ProcessPureBasicEvents 
EndProcedure

If OpenWindow(0, 0, 0, 500, 400, "Window", #PB_Window_SystemMenu | #PB_Window_ScreenCentered)
  
  SetWindowCallback(@WinCallback())
  
  Repeat
    Select WaitWindowEvent()
      Case #PB_Event_CloseWindow
        End
    EndSelect
  ForEver
EndIf

Thank you RSBasic, it works perfectly now

A subsidiary question: Is there a way to interrupt (or pause some seconds) the start of this sleep mode while something is displayed?
Maybe cancel the standby request completely, continue the program, then launch the software standby?
But I don't think Windows allows software to interrupt a stop command (as you can do under unix with shutdown)

(Put in extended sleep mode by command, I know how to do it with runprogram and rundll32.exe powrprof.dll,SetSuspendState 1,0,1)

In the past you could return #PWR_FAIL to abort the suspend, do stuff and later init suspend again. But it might not work with #WM_POWERBROADCAST anymore.
