puh, I find the error myself...
my client couldn't send because I thought I must use the Server Socket in the send() function!
there should be the socket of the client himself!
...as I started with sockets I saw that the Server was using the Client socket to send to the client, so I thought the Client should use the Server socket to send to the server...
...thats why I send the server socket int from the server to the client...
here the correct code :
erstmal mein Socket.h :
| C++: |
//Socket init
SOCKET sock; //variable du type Socket
SOCKADDR_IN sin;
SOCKET csock;
SOCKADDR_IN csin; //informations techniques du socket
int port = 50;//2388
char hostIP[]="127.0.0.1";//"62.214.238.147"
//CLIENT
void openclientsock ()
{
WSADATA WSAData; //Windows Socket Data, ou un truc du genre...
WSAStartup(MAKEWORD(2,0),&WSAData); //la version utilisée, ici v.2
sock = socket(AF_INET,SOCK_STREAM,0); //Cré un Socket appelé "sock"
sin.sin_addr.s_addr = inet_addr(hostIP); //l'addresse du server
sin.sin_family = AF_INET; //type de Socket
sin.sin_port = htons(port); //Port
}
//SERVER
void openserversock ()
{
WSADATA WSAData;
WSAStartup(MAKEWORD(2,0),&WSAData);
sock = socket(AF_INET, SOCK_STREAM, 0);
sin.sin_addr.s_addr = INADDR_ANY;
sin.sin_family = AF_INET;
sin.sin_port = htons(port);
bind(sock, (SOCKADDR *)&sin, sizeof(sin));
}
//CLOSE SOCKET
void closesock ()
{
closesocket(sock); //Protokol qui ferme le socket...
WSACleanup(); //..et le WSA
}
//EMPFANGEN
char* reccord()
{
char buffer[1024]={0};
int bytes;
bytes = recv(csock, buffer, sizeof(buffer) - 1, 0);
if (bytes == -1) {
//cout << "\n !couldn't retreave the message!\n";
system ("pause");
} else if(bytes >0) {
buffer[bytes] = '\0';
cout << "\nreceived message : "<<buffer <<endl;
}
return (buffer);
}
//Senden
void sende(const char* mess)
{
int bytes;
bytes = send(csock,mess,strlen(mess),0);
if (bytes == -1) {
system ("cls");
cout << "\n !couldn't send the message!\n";
} else {
cout << "\nmessage send : "<<mess <<endl;
}
}
