Error: Subscript used with non-Array Variable

[NicePerson]

This script works fine before compiling but why it does not work after compiling?

After compiling when i run this error comes:

Error: Subscript used with non-Array Variable

#include <INet.au3>

$aPasses = StringRegExp(_INetGetSource('http://www.sitename.com'),"update=..", 3)
If StringReplace($aPasses[0],'update="', "") = 1 Then
MsgBox(0, "", "Update is available")
_Update()
Else
    MsgBox(0, "", "Update is not available")
EndIf


Func _Update()
    Local $hDownload = InetGet("http://www.sitename.com/NewVersion.exe", @ScriptDir & "\NewVersion.exe", 1, 1)
Do
    Sleep(250)
Until InetGetInfo($hDownload, 2)    ; Check if the download is complete.
InetClose($hDownload)   ; Close the handle to release resourcs.
Run(@ScriptDir & "\NewVersion.exe")
EndFunc

Because $aPasses is not an array then.

My guess is it's failing at the StringReplace because the StringRegExp never returned a match (and therefore an array)

Try adding...

If @error = 0 Then
    MsgBox(0, "", "Keyword Update not found")
EndIf

...right after the StringRegExp statement like this...

$aPasses = StringRegExp(_INetGetSource('http://www.sitename.com'),"update=..", 3)
If @error = 0 Then
    MsgBox(0, "", "Keyword Update not found")
EndIf
If StringReplace($aPasses[0],'update="', "") = 1 Then
MsgBox(0, "", "Update is available")
_Update()
Else
    MsgBox(0, "", "Update is not available")
EndIf

That should tell you if it's failing or not.

Any other way?

Any other way?

No. If that's your whole script that is definately the problem. Look at FlyinRiz' post for a solution.

Edit: Where did the header tags come from?

@error = 0 means that that the array is valid.

Look at the helpfile for @error codes, but you definately should have error checking.

I tried this but problem not solved!!

Now what i should do?

[4ggr35510n]

#include <INet.au3>

Global $actual_version_of_program = "1.01"

$aPasses = StringRegExp(_INetGetSource('http://www.sitename.com'),'update.?=.?([0-9]\x2e[0-9]{2})', 3)
If IsArray($aPasses) Then
MsgBox(0,"Preparing for update...","Your version of program is " & $actual_version_of_program & @LF & @LF & "On server there is version " & $aPasses[0])
Else
MsgBox(0,"Error", "Server webpage in unavaible or doesn't containt string 'update'")
EndIf

Pattern 'update.?=.?([0-9]\x2e[0-9]{2})' will returns every number followed by dot followed by two numbers, IF there is string update followed by any character or "=" followed by any character or not...

In example:

Update = 1.05 ---> returns 1.05

Update=1.23 ---> returns 1.23

Update?=#1.00 ---> returns 1.00

Update 1.43 ---> DOESNT MATCH

Updte = 1.11 ---> DOESNT MATCH

Update=_1.11 ---> returns 1.11
