Keeping connection alive

I was wondering what i am doing to make the connection not stay alive for more than about 30 seconds. I am trying to connect to googles IP on port 80 and have the program keep the connection alive for a long time. I also want it to close the socket connection every few minutes and reconnect. I am trying to do this while hiding the command prompt from the user because my friend said it is impossible please help me

Code:

#include <iostream>
#include <windows.h>
#include <winsock.h>
#include <stdlib.h>
#include <time.h>
#include <string>
using namespace std;
int main(int argc,char *argv[])


    {
		int reconnect;

	//Hides command prompt from user
    HWND hwnd1 = FindWindow(NULL,argv[0]);
    ShowWindow(hwnd1,SW_HIDE);


    	string ip;
    	int port;

    	//Define ip and port
		//This is yahoo.com ip on http port right now
    	ip = "72.14.207.99";
    	port = 80;	
    	
    	WSADATA sockData;
    	WORD version;
    	SOCKET conn;
    	

    	int error;
    	

    	version = MAKEWORD(1,1);
    	

    	error = WSAStartup(version, &sockData);

    	conn = socket(AF_INET,
    			 	 SOCK_STREAM,
    				 IPPROTO_TCP);
    				 
    	SOCKADDR_IN Winsock;
    	
    	Winsock.sin_family = AF_INET;
    	Winsock.sin_port = htons(port);
    	Winsock.sin_addr.s_addr	= inet_addr(ip.c_str());
        connect:
    	//Connect on the socket
    	if(connect(conn, (SOCKADDR*) &Winsock, sizeof(Winsock)) == SOCKET_ERROR)


        	{
        		
        		cout << "An exception has occured (" << WSAGetLastError() << ")\n";
        		//Cleanup socket
        		WSACleanup();
        		system("PAUSE");
        		return EXIT_FAILURE;
        	}
		//cout << "Socket established";

        	//Close socket connection and reconnect
			Sleep(60000);
			//cout << "Socket reconnecting";
        	closesocket(conn);
        	return EXIT_SUCCESS;
			system("cls");
			goto connect;
		
    }
