Simple question(s)

Greetings,

I have an easy question regarding variables and their scopes.

Example:

AutoItWinSetTitle("Example")

Opt("TrayAutoPause", 0)
Opt("TrayIconDebug", 1)
Opt("MustDeclareVars", 1)

Global $Log = 0
; Is this now declared and initialized? Should I use OnAutoItStart() to initalize global variables?

While 1
   Sleep(1000)
WEnd

Func define()
   Local $defPath

   Local $defPath = Call("SomeFunction")
      If $Log == 1 Then
; Can I call this variable since it's declared already in a global scope?
         MsgBox(0,"Log","Actually, I would write to a log file, but you get a message box for the example!")
      EndIf
EndFunc

Thanks guys, I'm really bad at coding/dumb!

Is this now declared and initialized? Should I use OnAutoItStart() to initalize global variables?

Yes and no, better to put them at the top of the script. The other thing might cause warnings by au3check.

Can I call this variable since it's declared already in a global scope?

Yes

Ever wanted to call functions in another process? ProcessCall UDFConsole stuff: Console UDFC Preprocessor for AutoIt OMG

This Global $Log = 0 is fine, it will be declared and usable everywhere within your script.

This $Local defPath and this $Local defPath = Call("SomeFunction") are defined incorrectly, I'm assuming it's a case of mistyping where you put the "$" on them. You're declaring the variable $defpath twice, that's not correct, you only need to declare it once. Also, you don't NEED to use the Call command to run a function, you just need to run it like this, SomeFunction(), but using Call is ok as long as you don't need to use a ByRef parameter in the function.


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.

Greetings BrewManNH,

1.) Yes it was a typo.

2.) Call function purely for the example :)

3.) Edit: Oh, I spotted the confusion ;)

I found the culprit! It's a pretty stupid moment, but a certain function that I referenced earlier was registering 'before' the necessary variables were declared/initialized! Hence the error, duh!
