ContinueLoop in a Func

[atomman]

Normally if i want to abort a Case, i'd just use ContinueLoop. How would you do this if ContinueLoop is in a Func outside the loop?

It doesn't have to be ContinueLoop that is used, i just need to abort the Case.

Can you give more detail of how you want to do this? A small example script would be helpful. There are several ways of addressing this, depending on the details.

A function called from within a loop can not use ContinueLoop or ExitLoop inside the function, unless it has its own loop. Generally I would check the return value or @Error from the UDF call and then call ContinueLoop or ExitLoop accordingly. Again more details would be helpful.

Here ye go...

While 1
    $Msg = GUIGetMsg()
    Switch $Msg
        Case $Button_HlLnk
            _GoApp(); switch to App
        ; remainder of Case 
EndSwitch

Func _GoApp()
    If $Var = 1 Then
        MsgBox(262144, "Error!", "App not found!")
    ; ### substitute for ContinueLoop  goes here ###
    Else
        WinActivate($App)
        WinWaitActive($App)
    EndIf
EndFunc

I don't see why the code you have is a problem anyway (did you try using Return?), but you could wrap it in a once-only loop.

Func _GoApp()
  Do
    If $Var = 1 Then
        MsgBox(262144, "Error!", "App not found!")
        ContinueLoop ; Or maybe ExitLoop would be more appropriate, not sure what you're wanting exactly, so experiment
    Else
        WinActivate($App)
        WinWaitActive($App)
    EndIf
  Until True
EndFunc

I didn't see a problem either, but SciTE warns on ContinueLoop being outside a loop, even though technically it isn't since the func is being called inside a loop, and won't run the script.

So putting it in a a loop of it's own eliminates the SciTE problem, but i'm not getting the expected result. Below i added a MsgBox() that i don't expect to ever run, but it does.

As far as using Return, i think i understand basically what it's for, but i don't understand how to use it in this instance. I also tried ExitLoop in place of ContinueLoop and still get the MsgBox.

While 1
    $Msg = GUIGetMsg()
    Switch $Msg
        Case $Button_HlLnk
            _GoApp(); switch to App
            MsgBox(0,"","HELLO!")   ; ### not expecting to see this ###
            ; remainder of Case
        
        ; next Case
EndSwitch

Func _GoApp()
    Do
        If $Var = 1 Then
            MsgBox(262144, "Error!", "App not found!")
            ContinueLoop
        Else
            WinActivate($App)
            WinWaitActive($App)
        EndIf
    Until True
EndFunc
