Select Array value from Variable

[PresFox]

Hello,

The following code errors, something about a wrong or missing expression

#include <File.au3>
_FileReadToArray("useragent.txt", ByRef $aArray)
local $num = random(1,19)
HttpSetUserAgent($aArray[$num])

Can someone tell me whats wrong?

Delete the ByRef for starters.  Then without knowing what that file looks like I would say that it needs to have at least 19 values in it.  Also, the random function defaults to a float data type.  Add a third parameter of 1 to return an integer.  You don't want to get back 5.33 or something like that.

Edited it now to:

#include <File.au3>
_FileReadToArray("useragent.txt", $aArray)
local $num = random(1,19,1)
HttpSetUserAgent($aArray[$num])

the useragent.txt file has 20 values, but it still errors

You also need to set the path name to the file ...

_FileReadToArray(@scriptdir&"\useragent.txt", $aArray)

I don't know where the file is ... but if it is the same DIR as the script that is how you would find it.

Also, if you have 20 values rand(1,19) will never hit #20 ...

Declare $aArray

[jdelaney]

#include <File.au3>
Local $aArray[1]
_FileReadToArray("useragent.txt", $aArray)
If @error Then
    MsgBox(1,1,"file not found")
    Exit
EndIf
$num = random(1,UBound($aArray)-1,1)
HttpSetUserAgent($aArray[$num])

Why are you wanting to set the user agent string to a random value? What are you attempting to do with this?
