Turn off Recursion level

5 posts in this topic

Hello, I did not know how to word the title but basically my script gives me this message after a few minutes,

Recursion level has been exceeded - AutoIt will quit to prevent stack overflow.

How do I turn off this feature and prevent this message? Here is my script,

#Region ;**** Directives created by AutoIt3Wrapper_GUI ****
#AutoIt3Wrapper_Icon=upload.ico
#AutoIt3Wrapper_Res_Language=1033
#EndRegion ;**** Directives created by AutoIt3Wrapper_GUI ****
FileInstall("D:\upload2.ico", @ScriptDir & "\upload2.ico")
FileInstall("D:\upload.ico", @ScriptDir & "\upload.ico")
;$set = 0
pingfunc()
Func pingfunc()
    $ping = Ping("google.com")
    If $ping = 0 or $ping = 1 or $ping = 2 or $ping = 3 or $ping = 4 Then
        TraySetIcon(@ScriptDir & "\upload2.ico")
        ;If $set = 0 Then
        ;   MsgBox(64, "Network Offline", "Your OFFLINE!")
        ;   $set = 1
        ;EndIf
        pingfunc()
    EndIf
    ;If $set = 1 Then
    ;   $set = 0
    ;   MsgBox(64, "Network Online", "Your ONLINE!")
    ;EndIf
    TraySetIcon(@ScriptDir & "\upload.ico")
    pingfunc()
EndFunc   ;==>pingfunc

First off, you can't turn it off. It's telling you that you've seriously screwed up somewhere within your script and it's preventing a catastrophe.

Second, you're getting that warning because you're calling pingfunc() from within itself, you shouldn't be doing that.

Third, you're not reading the return from Ping correctly, it returns 0 if it can't reach the target, @error gets set to any of the other numbers you're looking for, not the return from ping.

Try it this way.

    While 1
        $ping = Ping("google.com")
        If $ping = 0 Then
            TraySetIcon(@ScriptDir & "\upload2.ico")
            ;If $set = 0 Then
            ;   MsgBox(64, "Network Offline", "Your OFFLINE!")
            ;   $set = 1
            ;EndIf
        Else
            ;If $set = 1 Then
            ;   $set = 0
            ;   MsgBox(64, "Network Online", "Your ONLINE!")
            ;EndIf
            TraySetIcon(@ScriptDir & "\upload.ico")
        EndIf
        Sleep(1000) ; sleep for 1 second
    WEnd
EndFunc   ;==>pingfunc

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

I hereby grant any person the right to use any code I post, that I am the original author of, on the autoitscript.com forums, unless I've specifically stated otherwise in the code or the thread post. If you do use my code all I ask, as a courtesy, is to make note of where you got it from.

Edit...beat me to it ^

Use a while loop...no recursion there.  BTW, recursion is when you use a function to call it's self again, and again, and again, etc

Recursion limit is pretty standard in most high-level programming languages.
