Singleton with ability to update script

[john_2019]

To prevent multiple instances of the same script I use "_Singleton" function:

#include <Misc.au3>


If _Singleton("ScriptID", 1) = 0 Then
    Exit
EndIf

HotKeySet("{F2}", "_test")

While 1
    Sleep(100)
WEnd

Func _test()
    MsgBox(64, "Title", "Content")
EndFunc

However, if I double-click this script, then change "Content" to "New content" and then double-click again - it will not be updated. It will be just "Content". How to fix it?

Also, another question: Is there more elegant way to prevent script from immediately exiting? Currently I use "while" for it.

your first script does not end. The hotkey is allocated to the first script and work fine.

The hotkeyset of the second script fails due to hotkey already defined.

@Exit I understand. But how to fix it? I came here from AutoHotkey world, and it was quite easy there: just add "#SingleInstance, Force" line in the top of the script and that's all.

Well, there is no option for it?

Change script name for second script.

@john_2019 Just use my UDF "_SingleScript.au3" 

Here a sample code

#include "_SingleScript.au3"  ; http://www.autoitscript.com/forum/index.php?showtopic=178681

_SingleScript()
HotKeySet("{F2}", "_test")
MsgBox(64 + 262144, Default, "Press OK and then F2", 0)
While 1
    Sleep(1000)
WEnd

Func _test()
    MsgBox(64+262144, Default, "Test 1",0)     ;  change text here to see difference
    Exit
EndFunc   ;==>_test

 

The _SingleScript.au3   code can be found here
