Hello,

Hey, I've read the thread by ups2000ups and tried it out with the dll and it worked great.
Source
Code:
library debugger;

uses
  SysUtils,
  Classes;

{$R *.res}
procedure Random()stdcall;assembler;
asm
mov byte ptr [$005CF4C1],$74
end;

exports
  Random;

begin
end.


$005CF4C1 is just a random address with "jne xxx..". in GMS v0.50.
So I injected the dll into MapleStory (ggles) and executed the function "Random" and it succesfully changed "jne" to "je". Smile

So I was wondering if it would be possible to inject the dll into MapleStory without calling a function.
Then calling the function aka procedure from a application that it executes it in MapleStory.
Or do I have to make a dll injector and inject the dll with executing the proedure?


thanks in advance Smile

He wants the function to run when it's injected.

reakw0n i dont think you could do that because you execute on the attach. idk though.

edit:

You need to use a timer.

Yes, you already told me that like 10 times.

Ontopic:
So the dll in C and the application in delphi. But how to call it then?

As soon as you inject the DLL, DLLMain is called. its like the int main(); function in a console application.

reakw0n did you read what i said?

in the main function create a timer or set a hotkey. use the keyboard sync with timer or WM_HOTKEY message with the hotkey.

From what I read it as, you want to have the DLL execute a function during runtime when a stand alone exe is performing an action, more or less so communicating with the DLL while its inside the process.

You can do this a few different ways:

- NamedPipes
- MMF (Memory Mapped File)
- MuteX Threading

MMFs
http://msdn2.microsoft.com/en-us/library/aa366761.aspx
(Not really any overview on this other then the functions, but yea thats one of the main functions used and some info on it and links to others on that page.)

MuteX Objects
