_Singleton

[Kurtferro]

Q3. How can I prevent more than one copy of my script from running at once / detect another copy of my script running?

If you simply want know if another copy is running, you can use code similar to the next example:

CODE: AutoIt

#include <Misc.au3>

If _Singleton("MyScriptName", 1) Then

; We know the script is already running. Let the user know.

MsgBox(0, "Script Name", "This script is already running. Using multiple copies of this script at the same breaks the [(UltimaCoder)] License!")

Exit

Endif

I have tried it but for me dont work.

I need a singol istance.

My script name is "ServerPorter"

[themax90]

#Include <Misc.au3>
_Singleton("ServerPorter", 0)

Putting this at the top of the script will detect when opened if another copy is open and Exit upon finding it.

I have already tried in all mode, but it never work with me, can be a problem with vista?

i have made this function:

Func CheckPID()

$list = ProcessList("ServerPorter.exe")
for $i = 1 to $list[0][0]
    if  $list[$i][1] <> @AutoItPID then
        msgbox(4096, $list[$i][0], "ServerPorter.exe is already executed!!")
        Sleep(5000)
        exit 0
    EndIf
next

EndFunc

This is another example of how to do that from the help file (FAQ section)

; Place at the top of your script

$g_szVersion = "My Script 1.1"

If WinExists($g_szVersion) Then Exit ; It's already running

AutoItWinSetTitle($g_szVersion)

; Rest of your script goes here

Try it out

I use _Singleton on a few scripts with no problems, including _Singleton(@scriptname, 1). I am runing XP SP2.

EndFunc

If your running Vista it doesn't hurt to put #RequireAdmin at the top of your code. Whenever I am making scripts that will be ran on a Vista system I just automatically put it in, it has made some work that should have otherwise been fine but wouldn't work.

Vista's security is a hassle for admins as well as many other things.
