My app needs to know how long it's been since my PC came out of standby. Any ideas on how to test for that? Thanks.

This page looks like it would serve. You could start counting a timer when your app receives WM_POWERBROADCAST with wParam = PBT_APMRESUMEAUTOMATIC and you'll always know how long since the last resume (sounds good on paper anyway) https://msdn.microsoft.com/en-us/librar ... s.85).aspx

Thanks netmaestro!

I was able to do it like this:

Code: Select all

Global awake

Procedure Callback(hWnd,Message,wParam,lParam)
  result=#PB_ProcessPureBasicEvents
  If Message=#WM_POWERBROADCAST
    Select wParam
      Case #PBT_APMRESUMESUSPEND
        awake=Date()
      Case #PBT_APMSUSPEND
        awake=0
    EndSelect
  EndIf
  ProcedureReturn result
EndProcedure

OpenWindow(0,200,200,200,100,"Time awake",#PB_Window_SystemMenu)
TextGadget(0,10,10,180,180,"")

SetWindowCallback(@Callback(),0)

Repeat
  ev=WindowEvent()
  If ev=0
    Sleep_(500)
    If awake
      SetGadgetText(0,Str(Date()-awake))
    EndIf
  EndIf
Until ev=#PB_Event_CloseWindow
