[Python/dll] It should work !

Hello.

I try to use python in my DLL i'm newbie :<

Code:

#include "windows.h"
#define MS_NO_COREDLL
#include <Python.h>
#include <detours.h>

#include "stdafx.h"
#include <string>
#include <sstream>
#include <iostream>
#include <fcntl.h>
#pragma comment(lib, "detours.lib")
using namespace std;

void pickupitem(){
	PyObject* args = PyTuple_New(0);
	PyObject* ret = PyObject_Call(PyObject_GetAttrString(PyImport_ImportModule("player"), "PickCloseItem"), args, NULL);
	double result = PyFloat_AsDouble(ret);
	Py_DECREF(ret);
	Py_XDECREF(args);
	//return result;
}
BOOL APIENTRY DllMain(HANDLE hModule, DWORD ul_reason_for_call, LPVOID lpReserved)
{
	switch (ul_reason_for_call)
	{
	case DLL_PROCESS_ATTACH:
		pickupitem();
		break;
	case DLL_THREAD_ATTACH:
		break;
	case DLL_THREAD_DETACH:
		break;
	case DLL_PROCESS_DETACH:
		break;
	}
	return TRUE;
}

I attach this to process (and it compile successfull but it dont pickup item in game)

Btw. what is the best dll + python injector ? I remember that i saw python + dll injector in one program (DE for metin)

// 2 my metin2 client is still running as administrator privillages.

I dont know how to remove it ( i dont set it in file proporties )

i think player.PickCloseItem don't have any return (None).

and its impossible to compile because a void function (must not return) returns double.

ohh i edit this in forum there i fix the code in 1st post. Sorry.

Btw. i try to inject this dll into P SERVER ..

I think it is fault of my VISUAL STUDIO.

Bcoz when i inject it by Winject (program to inject dll into process )

i have got injection failed.

But when i remove python func and change that when the dll is attach show message box - it works.

IF i make that :

Quote:

case DLL_PROCESS_ATTACH:
MessageBoxA(NULL, (LPCSTR) "WORK!", (LPCSTR) "YES !", NULL);
pickupitem();
break;

I saw 2x WORK! but python dont work and this injector still show error.

It is possible to debug this dll ?
And know whats wrong ? ;x

You can easily remove the administrator privileges with Resource Hacker. Here are the steps:

1. Download Resource Hacker from this site: [Only registered and activated users can see links. Click Here To Register...]
2. Open the binary in Resource Hacker and in the Folder tree go here: 24 > 1 > 1033
3. Replace this line:

Code:

<requestedExecutionLevel  level="requireAdministrator" uiAccess="false"></requestedExecutionLevel>

with this:

Code:

<requestedExecutionLevel level="asInvoker" uiAccess="false"></requestedExecutionLevel>

4. Go to File and click Save as, now Resource Hacker will save your binary without administrator privileges.

I don't get the point of using Python in c++ for Metin2.
Those Python-"Exports" are just c++ functions exported by metin2client.bin so the Python-scripts can use it.
Why don't you call them directly?
You are trying to:
c++ -> Python -> Python -> C++ -> Result

But you could simply do:
c++ -> c++ -> Result

ok i understand that python run c++ function.

But i dont understand why it dont work ?

IF i make that :

Quote:

case DLL_PROCESS_ATTACH:
MessageBoxA(NULL, (LPCSTR) "WORK!", (LPCSTR) "YES !", NULL);
pickupitem();
break;

I saw 2x WORK! but python dont work and this injector still show error.

Maybe you need to link to the python lib?

01/25/2014 14:57 dramcio#8

IN: project > proporties > linker > additional libary directories > C:\Python27\libs

Whats more?

Halo. You can use python in dll , but why me cant ?:x

I paste python27.dll into metin2.

2. It is possible to debug this dll?

Py_initalize() - crash Metin2 ;0
