How to send an object to a namespace (a graphic interface type class) and set the object to be used by C ++ button actions

I am working on a project that has two administrators connected to a server through sockets and threads. Includes graphic interface. The problem arises when I want to send objects of type socketC to the interface so that each interface sends data to socket of the server but I can not find a way to set them in the interface. The administrator code that creates the sockets objects and sends them to the interface

using namespace System;
using namespace System::Windows::Forms;
using namespace std;
using namespace AdministradorS;

struct arg_struct {
    SOCKET socket;
    int puerto;
    string ip;
};


void* crearSocketCliente(void *datosRec) {
    struct arg_struct *datos = (struct arg_struct *)datosRec;
    socketC sCliente1(datos->puerto, datos->ip, datos->socket);
    Application::EnableVisualStyles();
    Application::SetCompatibleTextRenderingDefault(false);
    AdministradorS::loginAdmi loginAdmi_sec(sCliente1);
    loginAdmi_sec.ShowDialog();

    return NULL;
}


void main()
{
string ipAddress = "192.168.0.6";           // IP Address of the server
int port1 = 5400;                       // Listening port # on the server
int port2 = 5500;
SOCKET SocketAdministrador1 = NULL;
SOCKET SocketAdministrador2 = NULL;
struct arg_struct datosAdministrador1;
struct arg_struct datosAdministrador2;
datosAdministrador1.socket = SocketAdministrador1;
datosAdministrador1.puerto = port1;
datosAdministrador1.ip = ipAddress;
datosAdministrador2.socket = SocketAdministrador2;
datosAdministrador2.puerto = port2;
datosAdministrador2.ip = ipAddress;


pthread_t thread1, thread2;
pthread_create(&thread1, NULL, &crearSocketCliente, (void *)&datosAdministrador1);
pthread_create(&thread2, NULL, &crearSocketCliente, (void *)&datosAdministrador2);
pthread_join(thread1, NULL);
pthread_join(thread2, NULL);


// Gracefully close down everything
closesocket(SocketAdministrador1);
closesocket(SocketAdministrador2);
WSACleanup();
}

Code of an interface window (the one of logearse the administrator) that receives the object, tries with a variable static but sets a single object therefore the two interfaces created handle the same socket

My question in general is how to create a variable in the code of the interface that can set the incoming object and thus be used in the action of the button? (I can not create variables in a normal way since an error occurs that the variable was already created, I guess, because of the threads) Thank you in advance and I hope I have expressed myself well in my question, sorry if the code has a lot of commented section or I am new.
