If script exists/already running

[RoundChecker]

Hi everyone,

Is there a way to determine whether the script that is running, is already running, without using;
 

If WinExists

?

Or is there a way to use "If WinExists" to determine the script itself?

The reason I am asking this is because if I want someone to run the .Exe I have and they rename it to whatever they want, how could I then determine in the script to check if there's already an .Exe open, or the script itself is already open?

Should I use Class, or how do I achieve this?

Thanks in advance.

Look up _Singelton in the help file.

Thanks for your answer.

 

If _Singleton("test", 1) = 0 Then
    MsgBox($MB_SYSTEMMODAL, "Warning", "An occurrence of test is already running")
    Exit
EndIf
MsgBox($MB_SYSTEMMODAL, "OK", "the first occurrence of test is running")

("test",

This is the identification of the title of the script, correct? - If the script name were changed, wouldn't it still be possible to run it twice after changing the name?

 

Or did I get it wrong? - Thanks in advance.

Should I maybe use

WinGetState

And refer to the Class:

AutoIt v3 GUI

instead?

Is there a way to refer to the script directly to get the script name, instead of typing in the name? like "@. .  "
Would this suffice?

If _Singleton(@ScriptName, 1) = 0 Then
    MsgBox($MB_SYSTEMMODAL, "Warning", "An occurrence of test is already running")
    Exit
EndIf
MsgBox($MB_SYSTEMMODAL, "OK", "the first occurrence of test is running")

@ScriptName <

You can put this in the first line of your script to check if it's running or not:

If _Singleton(@ScriptName,1)=0 Then Exit MsgBox(262144+16,"Error!",@ScriptName&" is already running!")

Yeah thank you that should do, was just wanting to make sure that it would work with using @, thanks again.

Solved - request close.

How about trying it, and DON'T use @scriptname as the parameter because then if someone does rename it and run it again with the new name, this check will fail.

That works, thanks again.

You're right, didn't think about this one

By the way, you put anything you want in the first parameter of _Singleton, any string will work in there. Just don't use anything tied to the name of the script that's interpreted at runtime such as any of the @Script* macros.
