Using Hotkey to stop a function

[Jewtus]

I'm wondering if there is a way to make a hot key stop performing a function (regardless of the function) without closing the script.

What I would like to have happen is when I hit ESC it will stop the function from continuing but it won't close the application. I tried using ExitLoop, but that only works while its inside a loop. Does anyone have suggestions?

Here is a sample of my code:

expandcollapse popup

#include <IE.au3>
#include <Misc.au3>

Opt("TrayMenuMode", 3)
$idLaunch=TrayCreateItem("Launch   CTRL+1")
TrayCreateItem("") ; Create a separator line.
$idExit=TrayCreateItem("Exit")
HotKeySet("{ESC}", "Hault")
local $oIE

While 1
    If _IsPressed(11) AND _IsPressed(31) then Open() ;ctrl+1
    ;Begin Tray options
    Switch TrayGetMsg()
        Case $idLaunch
            Open()
        Case $idExit
            Exit
    EndSwitch
WEnd


Func Open()
    Send("{CtrlUP}")
    $sURL = "http://www.google.com"
    Global $oIE = _IECreate($sURL, 0, 1, 1, 1)
    WinSetState("[ACTIVE]", "", @SW_MAXIMIZE)
    Sleep(2500)
    WinSetState("[ACTIVE]", "", @SW_MINIMIZE)
    Sleep(2500)
    WinSetState("[ACTIVE]", "", @SW_MAXIMIZE)
    Sleep(2500)
EndFunc

Func Hault()
    Exit
EndFunc

If you want to exit the function by pressing ESC without closing the script, you need a local boolean variable, that you initialize this way: 

Local $bExitNow = False

Your function "Haul() needs to change to this:

Func Haul()

$bExitNow = true

EndFunc

Then you insert these lines in your Open() function wherever you want to stop it, probably in front of each WinSetState line and each Sleep line

If $bExitNow = true then

$bExitNow = False ; this will keep the ESC keypress effect temporary

ExitFunction

EndIf

I hope that solves your problem

I'm not sure I understand. I added this code, but it is saying that "ExitFunction" is not defined. If I use an exit command, it exits the entire script. What am I missing? I need it to only halt the function.

Jewtus.

The Interrupting a running function tutorial in the Wiki shows how you do this.

ahhh ok I get it. Pretty simple once you see it in action.

 

Thanks all

Delighted the tutorial helped - makes writing it worthwhile when you get comments like that.
