Warnings: possibly used before declaration

9 posts in this topic

Hi,

I can't understand why these warnings shows up.

What can be the possible reasons?

Becuse it seems to be Ok , they are actuall declare.

(Also I uses some other scripts, when the main script contains them with includes)

Thanks

You're using a variable before you declare it. If you post the code we explain it further.

ok .. add the below line to your code next to Header files. And when you run the code that will tell you what are all the variables need to be declared before compile or executing..

[autoit]

Opt("MustDeclareVars",1)

[/autoit]

Hope this helps you!

Hi Syed,

it's exactly the other way round. Somewhere in his code there is already this Opt statement or a wrapper directive and somewhere he has an undeclared variable.

But without code and the full error message it's hard to say where the problem is.

It's a little bit hard to post the code here because I'm using some other scripts with the main script. Download Link for the program: http://www.mediafire.com/?xajej65p06q22bw (The main script is: AMT_Main_tmp.au3 I give you a little explantion For Example: In the main script I write:

#include "SomeOtherScript.au3"
Global Const $TEMP = 2
Then I'm running here a function which exist in "SomeOtherScript.au3" which uses this Global Const var Thats All.

The Constant is defined after the #include, right?

As AutoIt is interpreted top down the Constant is unknown to AutoIt when the Syntax check is beeing done. Example:

Func test()
    ConsoleWrite($Global & @CRLF)
EndFunc
Global Const $Global = 2
Test()

Move the Const to the top of the file and everyhting will be fine:

Global Const $Global = 2
Func test()
    ConsoleWrite($Global & @CRLF)
EndFunc
Test()

But I would recommend to define all variables and constants you need in the include-file itself.

yes it help,

I raise them aboce the includes so it works now.

I put them in the main script because they are used by some scripts (not only by one)

Good practice:

Create/Declare all global constants in a file and include it in the begining of the main script.

@PS Very usefull for large scripts with a lot of constants and global variables.
