Hi ,everyone!

I want write a programme to temprary block my computer to enter standby and hibernate , show a messagebox before enter these state, , How can I do this?

Is this required API hook ? I know the hibernate api is SetSuspendState, How can I hook it ?

Thank you very much for your help!

This could help.

This topic is just discuss how to detect the monitor is on or off , blocking the standby event is not solved , May be I must solving this problem by hooking api , However, I don't know how to making it possible , I hope someone give me a example, I'm very appreciate,

#include <WinAPI.au3>
#include <WindowsConstants.au3>
#include <StructureConstants.au3>

Opt('MustDeclareVars', 1)

Global $hHook, $hSuspend

_Main()

Func _Main()
    Local $hmod

    $hSuspend = DllCallbackRegister("SetSuspendState", "int", "int;int;int")
    $hmod = _WinAPI_GetModuleHandle(0)
    $hHook = _WinAPI_SetWindowsHookEx($WH_GETMESSAGE, DllCallbackGetPtr($hSuspend), $hmod)


    While 1
        Sleep(10)
    WEnd
EndFunc  ;==>_Main


;===========================================================
; callback function
;===========================================================
Func SetSuspendState($nCode, $wParam, $lParam)
    MsgBox(0,$nCode,$wParam)
    Return _WinAPI_CallNextHookEx($hHook, $nCode, $wParam, $lParam)
EndFunc  ;==>_KeyProc

Func OnAutoItExit()
    _WinAPI_UnhookWindowsHookEx($hHook)
    DllCallbackFree($hSuspend)
EndFunc  ;==>OnAutoItExit

these code is not working , Why?
