Why does my timer freeze?

[blindwig]

I am writing a simple script that will use a timer. I wrote most of the script, but when I add the timer, it freezes the script to the point where I have to End Task on it. Trying to figure out what is causing the freeze, I cut the script down to it's most basic pieces, but it is still freezing.

Can someone tell me why?

Here is the most basic code I have, which still freezes on my PC:

#include <ButtonConstants.au3>
#include <GUIConstantsEx.au3>
#include <StaticConstants.au3>
#include <WindowsConstants.au3>
#include <timers.au3>

$frmAutoClicker = GUICreate("AutoClicker", 105, 65, 192, 114)
GUISetState(@SW_SHOW)

Func DoNothing()
EndFunc

$tmrAutoCLick = _Timer_SetTimer($frmAutoClicker,2000,"DoNothing")

While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch
WEnd

It's a failing of the help file because it should tell you that the function must have 4 parameters even if you don't use them. so

#include <ButtonConstants.au3>
#include <GUIConstantsEx.au3>
#include <StaticConstants.au3>
#include <WindowsConstants.au3>
#include <timers.au3>

$frmAutoClicker = GUICreate("AutoClicker", 105, 65, 192, 114)
GUISetState(@SW_SHOW)

Func DoNothing($a,$b,$c,$d)
#forceref $a, $b, $c, $d; set these variables as 'referenced' so the compiler doesn't complain they haven't been used.
EndFunc

$tmrAutoCLick = _Timer_SetTimer($frmAutoClicker,2000,"DoNothing")

While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch
WEnd

Edit: Added the #forceref line

Ah, I see it now. In the help page for _Timer_SetTimer is the example, which runs just fine of course, with 2 timer-called functions, declared thusly:

Func _UpdateStatusBarClock($hWnd, $Msg, $iIDTimer, $dwTime)
    #forceref $hWnd, $Msg, $iIDTimer, $dwTime

Func _UpdateProgressBar($hWnd, $Msg, $iIDTimer, $dwTime)
    #forceref $hWnd, $Msg, $iIDTimer, $dwTime

These functions have the 4 parameters, but as you stated, the help page fails to state that timer-called functions MUST have these parameters.

OK, problem solved, thank you very much for your help.
