Any way to 'Break' a Function? So it stops executing...

[StrategicX]

Hey guys,

Wonderin if anyone knows how to stop a function from completing if an If--Then statement becomes true, Im having a problem with detecting one thing with an If--Then statment that calls a dif, function if the expression is true, But after that function is done, the one called before it finishes and ruins things, since its wayyy out of order. Thanks guys,

p.s Im pretty sure thats called 'Break' in C++ but in autoit, break is comething totally different....

break's AutoIt counterpart is ExitLoop. If you want to exit or return from a function just use the Return keyword.

put it in a loop?

$i=0

do

if then

else

$i=1

this()

endif

until $i=1

iseem to have troubles understanding what your saying

'Break' in C++ only terminates a loop (While, If, etc) not a function. In AutoIt, ExitLoop does the same thing. There are a number of ways to achieve what you what, but I can't think of any particularly elegant ways to do it. One obvious way would be a flag and contain the remainder of the function in an If loop so that once the sub-function executes, the remainder of the primary function does not.

$keepgoing = true
Func 1
  Do some stuff
  Func2()
  if $keepgoing then
    Do some more stuff
  endif
endfunc
func 2
  Do some stuff
  $keepgoing = false
endfunc

Edit; Ha! Good thinking Authenticity! I should've thought of that option lol

This is how I do it, not sure if that's what you're looking for.

#include <ButtonConstants.au3>

#include <WindowsConstants.au3>

Local $loop = 0

$BreakLoop = GUICreate("Break Loop", 218, 101, 193, 125)
$Status = GUICtrlCreateLabel("Loop : ", 24, 10, 75, 25, 0)
$GO = GUICtrlCreateButton("GO", 24, 48, 65, 25, 0)
$Cancel = GUICtrlCreateButton("Cancel", 104, 48, 75, 25, 0)
GUISetState(@SW_SHOW)

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

Func loop()
While 1
    
        GUICtrlSetData($Status, "Loop in Progress: " & $loop)
        
            $nMsg = GUIGetMsg()                                     
                If $nMsg = $Cancel Then 
                    $Abort = MsgBox(36, "Cancel?", "Are you sure you want to cancel?")
                        If $Abort = 6 Then
                            ExitLoop
                            Return
                        EndIf
                EndIf
        $loop = $loop + 1
WEnd
EndFunc ;loop

I got a problem to exit from a loop with a SLEEP inside it.

Im gonna use your code as an exemple. I click on CANCEL to ExitLoop, but it doesnt work.

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

Local $loop = 0

$BreakLoop = GUICreate("Break Loop", 218, 101, 193, 125)
$Status = GUICtrlCreateLabel("Loop : ", 24, 10, 75, 25, 0)
$GO = GUICtrlCreateButton("GO", 24, 48, 65, 25, 0)
$Cancel = GUICtrlCreateButton("Cancel", 104, 48, 75, 25, 0)
GUISetState(@SW_SHOW)

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

Func loop()
While 1
    GUICtrlSetData($Status, "Loop in Progress: " & $loop)
    $nMsg = GUIGetMsg()
    If $nMsg = $Cancel Then
        $Abort = MsgBox(36, "Cancel?", "Are you sure you want to cancel?")
        If $Abort = 6 Then
            ExitLoop
            Return
        EndIf
    Else
        Sleep(500)
        $loop = $loop + 1
        Sleep(500)
    EndIf
WEnd
EndFunc ;loop

Any idea?
