_Timer_SetTimer no window

[Champak]

How can I use the _Timer_SetTimer and _Timer_KillTimer functions without a window or something similar?

You could do like this (example) - but depending of the use there are probably simpler ways to get the same result...

#include <Timers.au3>

HotKeySet("{ESC}", "Terminate")
Tooltip(StringFormat("%02d:%02d:%02d", @HOUR, @MIN, @SEC), 0, 0)

_Example_CallBack()

Func _Example_CallBack()
    Local $hGUI = WinGetHandle(AutoItWinGetTitle())
    _Timer_SetTimer($hGUI, 1000, "_UpdateTip") ; create timer
    While 1
       Sleep(10)
    WEnd
EndFunc   ;==>_Example_CallBack

; call back function
Func _UpdateTip($hWnd, $iMsg, $iIDTimer, $iTime)
    #forceref $hWnd, $iMsg, $iIDTimer, $iTime
    Tooltip(StringFormat("%02d:%02d:%02d", @HOUR, @MIN, @SEC), 0, 0)
EndFunc   

Func Terminate()
    Exit
EndFunc   ;==>Terminate

Thanks.

Just a suggestion, maybe it's my error in interpretation, but I think it would be a good idea to add the "WinGetHandle(AutoItWinGetTitle())" as a part of the remarks, because the way the help is worded lead me to believe that without a gui window existing in the script calling the timer function it would not work. "Handle to the window to be associated with the timer. This window must be owned by the calling thread". Or something a little clearer.

It seems that the hwnd can be 0 :

_Timer_SetTimer(0, 1000, "_UpdateTip")

MSDN says : A handle to the window to be associated with the timer. This window must be owned by the calling thread. If a NULL value for hWnd is passed in along with an nIDEvent of an existing timer, that timer will be replaced in the same way that an existing non-NULL hWnd timer will be.
