i am getting pretty anoyed at this, im using FDSTalk.dll to talk to FDS and i had it working but now it doesn't work why? here is the code i am using:(C++)

long IP2Long(std::string &ipString) //function from drichards (experts-exchange)
{
    long result = 0;									
    size_t startPos = 0;
    for ( int ii = 0; ii < 4; ii++ )
    {
        size_t dot = ipString.find('.', startPos);
        int num = ::atoi(ipString.substr(startPos, dot-startPos).c_str());
        result *= 256;
        result += num;
        startPos = dot+1;
    }
    return result;
}


int _tmain(int argc, _TCHAR* argv[])
{
	if(Init(1234, "password"))
	{
                cout << "Init";
		Send_Message("password", IP2Long((string)"127.0.0.1"), 4849);
		Send_Message("msg hello", IP2Long((string)"127.0.0.1"), 4849);
		Shutdown();
	}
	system("pause");
	return 0;
}



it will compile and run with no errors but nothing apperes in FDS, why!

}



heres my IP2LONG


if you going to close the connection to the FDS, its also good practice to send off

Send_Message("bye", IP2Long((string)"127.0.0.1"), 4849);



you could also try hard codeing the IP2LONG value for 127.0.0.1, which is what i do on NR Smile, it is: 16777343

Thanks you so much! it turns out that i need ::htonl, but i coulnt get it to compile so i removed it.

btw: how is your NR going in c++, i saw your thread at experts exchange.
