A Function counter?

[Nexx]

Hello you all, this is my first thread . I'm just asking what's the way (if there is of course), to make a function counter. I'll explain; in a script like this one...:

_Function1

Func _Function1
msgbox(1,"hello","bye")
_Function1
EndFunc

... the function1 is going to repeat itself all the time. What I'm searching and I can't find a way to do it, is to count the times that the _Function1 has been executed. Is there any way? How? Thanks for your time, waiting for answers

There is no way to do that.

_Function1()

Func _Function1()
    Local Static $iCounter
    $iCounter += 1
    If $iCounter > 3 Then Return
    MsgBox(1, "hello No" & $iCounter, "bye No" & $iCounter)
    _Function1()
EndFunc

trancexx,

What do you mean "does not work" "no way to do that? This was paraphrased from your code:

local $icounter
_Function1()
MsgBox(1, "hello No" & $iCounter, "bye No" & $iCounter)

Func _Function1()
    $iCounter += 1
    If $iCounter > 3 Then Return
    _Function1()
EndFunc

and it works.

@Nexx,

First, welcome to the forum.

Now your function1 isn't _repeating_ but _recursing_ and will promptly reach the recursion limit if no suitable logic blocks recursion at some reasonable point. With this in mind "the function1 is going to repeat itself all the time" is a dead end. I'd bet that your want the function to repeat in a loop instead of recurse upto crash.

BTW the static variable can help but remember that static is still an unstable feature. OTOH a global variable initialized to 0 and incremented at every function1 invokation will do as well, less elegantly but without relying on any "use at your own risk" feature (see keyword static in help).

Why not just pass the counter to the function as a parameter?

_Function1()

Func _Function1($iCounter=1)
    If MsgBox(1, "_Function1", "I was called " & $iCounter & " time(s)") = 2 Then
        Exit
    EndIf
    $iCounter +=1
    _Function1($iCounter)
EndFunc

Run your Example Stanislav and you will get >> Recursion level has been exceeded - AutoIt will quit to prevent stack overflow.: This is what jchd was talking about calling the same Function over and over without Returning from the previous Function, it's like an infinite mirror!

[Stanislav]

Oh! Now I got it - there are 2 limits, MAXCALLRECURSE and MAXEXECUTERECURSE: Maximum number of times functions can recurse to themselves (5100).

Thank you!
