Vexus Posted July 20, 2011 Share Posted July 20, 2011 (edited) 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!

Shaggi Posted July 20, 2011 Share Posted July 20, 2011 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?

BrewManNH Posted July 20, 2011 Share Posted July 20, 2011 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.Give a programmer the correct code and he can do his work for a day.

Vexus Posted July 20, 2011 Author Share Posted July 20, 2011 (edited) Greetings BrewManNH, 1.) Yes it was a typo. 2.) Call function purely for the example 3.) Edit: Oh, I spotted the confusion Edited July 20, 2011 by Vexus Link to comment Share on other sites More sharing options...
Vexus Posted July 20, 2011 Author Share Posted July 20, 2011 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!
