using Global Variables

Recommended Posts

I am having some trouble getting the GLOBAL variables declared.

If I am declaring any Variable as Global in the top of the script, it should be applied in throughout the code.

But I see that I still have to provide Global $Path after each "Case" to be able to identify it. If the "Case" looks for the $Path and I do not provide after any of the "Case" then that Case does not provide correct results.

 

Just to add here that, my code is too huge and has loads of Globals and Cases declared. So, wanted to check is it required to re-declare the Global $Path both at the top and again wherever needed?

Global $Path = "C:\Program Files (x86)\FolderName\FileName"

While1
    Select
        Case Fileexists($Path)
        Global $Path = "C:\Program Files (x86)\FolderName\FileName"
        FindFile1()
    Endselect
    
    Select 
        Case Not Fileexists($Path)
        Global $Path = "C:\Program Files (x86)\FolderName\FileName"
        FindFile2()
    Endselect
Wend

Func FindFile1()
    Code.....
Endfunc

Func FindFile2()
    Code...
Endfunc

Global $Path = "C:\Program Files (x86)\FolderName\FileName"

While
    If Fileexists($Path) Then
        FindFile1()
    Else
        FindFile2()
    EndIf
    Sleep(1000) ; Check every second
Wend

Func FindFile1()

Endfunc

By definition Global is global and does not need to be redefined.
Either you are using a Local with the same name in a function or you are assigning a new value to the Global somewhere in your script.
As you didn't post the full code we can't help any further.

This is how you'd write it, although in this code reassigning the $Path variable is pointless as the variable already contains the data you're assigning to it in the Select statements.

Global $Path = "C:\Program Files (x86)\FolderName\FileName"

While1
    Select
        Case Fileexists($Path)
            $Path = "C:\Program Files (x86)\FolderName\FileName"
            FindFile1()
   
        Case Else
            $Path = "C:\Program Files (x86)\FolderName\FileName"
            FindFile2()
    Endselect
Wend

Func FindFile1()
    Code.....
Endfunc

Func FindFile2()
    Code...
Endfunc

 

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.

Do not forget to insert a Sleep statement into the While loop. Else the script will eat up all your CPU.
