Looking for example code (all info in thread)

[owadziak]

Hello there everyone.

I hope there is someone who could help me a bit.
(Im not looking for full code , just for simple example how this could be done)
im working on a bot for Royal Quest.
I know a way to run multiple clients in one pc without VMWare etc
to do that i need to kill 2 "Event's" inside running process
I know how to do that manually using process exploler. But i would like to automate that , using build in script in to my bot. (
These two actually (Handle 0x120 and handle 0x108 )

I tried to find any Tutorial or script example , but without success
Spend like 4 hours , trying to figure it out by my self
using _WINAPI_CloseHandle function but i failed


so any help from community is appreciated

Sorry, I have no clue what that screenshot should tell me and what kind of events you are talking about. WinAPI sometimes references to Events as Threads so maybe you are talking about threads. But BaseNamedObjects can also refer to Mutexes or Semaphores or "Events" ... so ... ?

I guess these are the real WinAPI Events.

 Useless side information

An Event is created by CreateEvent and is used for synchronisation and/or locking purposes.

HANDLE hEvent = CreateEvent(NULL, TRUE, FALSE, _T("MyEvent));

A thread can now wait for the Event to be triggered

if (WaitForSingleObject(hEvent, 10000) == ...)
{
    // Handle different return values
}

While something can trigger the Event using SetEvent

SetEvent(hEvent);

Events are managed in the kernel by reference counting. There is no certain way to "delete" an event. The kernel will release the event once the last reference to it has been closed. CloseHandle states that it will also "delete" events, but I'm unsure how the kernel will actually handle this.

Long story short: CloseHandle seems to be your only hope. There is only one trick to it: You need to call it inside the target process. An external process can not access the internal handles of another process. Therefore you need to inject a DLL or "simply" call CreateRemoteThread.

The question is now do you find the handles? Are they deterministic aka. can you guess them?

seems like this one never change, doesnt matter how many client i open even if i open that game in different pc.

 Spoiler

Maybe this screen will help u figure out anything

                                $value = Int ($Data[$i][0])
