"ERROR: INVALID UTP-8 SEQUENCE: n Ya que el equpo d"...¿why?
why the code throws the error?

void iniciarConeccion(char nombreMaquina[],char paisMaquina[]){
char respuesta1[]="vacio";
char respuesta2[]="vacio";
WSAStartup(MAKEWORD(2,2), &wsa);

Winsock=WSASocket(AF_INET,SOCK_STREAM,IPPROTO_TCP,NULL,(unsi gned int)NULL,(unsigned int)NULL);
host = gethostbyname("localhost");
localIP = inet_ntoa (*(struct in_addr *)*host->h_addr_list);

direc.sin_addr.s_addr = inet_addr(localIP);
direc.sin_family=AF_INET;
direc.sin_port=htons(999);

if(Winsock==INVALID_SOCKET)
{PromptOK("ERROR ");}

if((WSAConnect(Winsock,(SOCKADDR*)&direc,sizeof(direc),N ULL,NULL,NULL,NULL))==SOCKET_ERROR){
String error=MensajeError(GetLastError());
PromptOK(error);
}

fromlen=sizeof(direc);
while(strcmp(respuesta1,"vacio")==0){
if(sendto(Winsock,nombreMaquina,sizeof(nombreMaquina),0,(str uct sockaddr *)&direc, sizeof(direc))==-1)
{
PromptOK("ERROR");

}
_sleep(5000);
recvfrom(Winsock,respuesta1,sizeof(respuesta1),0,&addr,& amp;fromlen);
}//system("PAUSE");
while(strcmp(respuesta2,"vacio")==0){
sendto(Winsock,paisMaquina,sizeof(paisMaquina),0,(struct sockaddr *)&addr, sizeof(addr));
{
PromptOK("ERROR");}
_sleep(5000);
recvfrom(Winsock,respuesta1,sizeof(respuesta1),0,&addr,& amp;fromlen);
}
WSACleanup();

}

Hello nietzfock

It would be better if you include all the code (in a reduced form) and indicate where that message appear. Anyway, probably the place is here:

String error=MensajeError(GetLastError());
PromptOK(error);

Could you send us the raw message?

Best regards

yes, you have reason the message here ("invaled utf-8 sequence: n Ya que el equpo d"). ¿Why?. What am I doing wrong?.

PD: sorry but my English is very bad

Hello nietzfock

Your code is incomplete, and there are many variables undeclared, so I imagine they are global variables. I have tried to make it work and I have replaced MensajeError() with GetErrorMessage().

The error message got is:

No se puede establecer una conexión ya que el equipo de destino denegó expresamente dicha conexión.

The error is the WSAECONNREFUSED (10061). There is an explanation here, and the reason usually is that your trying to connect to an address and a port where nobody is listening.

Hello Nietzfock

You are welcome!

If you fill more comfortable you can also make your questions in your language. I would translate them for all to my simple ( Rolling Eyes

) English.

Best regards
Iñaki
