you can do with dll.

example:

main.cpp (its good or no idk, but its working fine.)

#include "main.h"
#include "Winuser.h"
#include <process.h>


void TitleReplaceHookThread(void *param)
{
    DWORD pid = 0;
    DWORD current_pid = GetCurrentProcessId();
	while(true)
	{
		Sleep(50);
		HWND hWnd = FindWindow(NULL, "Lineage II");
		GetWindowThreadProcessId(hWnd,&pid);
		if(hWnd&&current_pid==pid)
        {
        SetWindowText(hWnd, "My Server Name");
        break;
        }
	}
}

extern "C" DLL_EXPORT BOOL APIENTRY DllMain(HINSTANCE hinstDLL, DWORD fdwReason, LPVOID lpvReserved)
{
    switch (fdwReason)
    {
        case DLL_PROCESS_ATTACH:
             HANDLE hThread;
            hThread = (HANDLE)_beginthread(TitleReplaceHookThread, 0, NULL);
            CloseHandle(hThread);
            break;
    }
    return TRUE;
}

main.h

#ifndef __MAIN_H__
#define __MAIN_H__

#include <windows.h>

#ifdef BUILD_DLL
    #define DLL_EXPORT __declspec(dllexport)
#else
    #define DLL_EXPORT __declspec(dllimport)
#endif

#endif

compile and put ur dll file to ur l2 system folder. to compile you can use simple tool `CodeBlocks`

 

and then use CFF Explorer

1. Open window.dll
2. Click Import Adder
3. Add dll file.
4. Select Exported function `DllMain@` and click Import by Name and then click Rebuild Import table.
5. save window.dll
done.

The code throws an error while compiling, does anyone have an alternative code ?
