One same application limits multiple scripts - (Moved)

[AndSoW]

This is a script that can open multiple same applications, as long as you find the mutex name, close the application thread opened before, and start a new thread program, you can achieve the purpose of opening multiple applications. (Script source ACN, and not tested, please test yourself) Do you have any other better method code? I want to be able to open each thread and return a process ID. Good luck!

This is a problem script, has not found the reason, would like to ask you to help cattle!

Cattle...I went to Alberta once (Province in Canada), and they leave beefs free in the mountains.  So in order to prevent accidents, they have signs saying, "Help Cattle to stay Free".  Funny...

So, not tested but has a problem.
What are you trying to accomplish ( regardless of the script you posted ).

i 'm sorry! I have tested the script and achieved form thread exclusion using [_WeChattApp_Instance_Identity-MutexName], which allows for unlimited startup of the same program, but this feature is not effective. Can you help me? I think the script can achieve unlimited startup of the same program, but it can also not close existing programs that have already been opened？thank!

Hey,

Dunno how you're confident with msdn, windows native stuff, etc and maybe about programming itself ...

But to make it simple (and i don't get why you asked that for so i just gonna explain how it works without example (don't have time to check the pasted code you provided, and mainly this kind of stuff is usually used for some sus application)).

So in one line :

You can't close the mutex itself. You have to duplicate it and free the copy : windows "kills" the original handle when you free the dup handle.

 

/Regards

NB: maybe this is not what you're trying to accomplish, but it's hard to understand your goal: openning infinite instances of a program limited by a mutex (that's what i explained) ? opening, killing then reopening a same program an infinite number of time ?
