Hey There,

I have the following problem:

I am starting WSA, then I am creating a UDP socket (AF_INET, SOCK_DGRAM, IPPROTO_UDP) and try to recvfrom on this socket, but it always returns -1 and I get WSAEINVAL (10022)... I don´t know why?...

When I bind the port, that does not happen...

But it is very lame to bind the clients socket... (As far as I remember, i never had this problem before:/ )...

Anyone knows why this happens?...

(I am sending data to my server, which anwsers[ or at least, tries to^^])...

Inc::STATS CConnection::_RecvData(sockaddr* addr, std::string &strData)
{
    int ret, len, fromlen;      //return code / length of the data / sizeof(sockaddr)
    char *buffer;       //will hold the data
    char c;

    //recv length of the message
    fromlen = sizeof(sockaddr);
    ret = recvfrom(m_InSock, &c, 1, 0, addr, &fromlen);
    if(ret != 1)
    {
#ifdef __MYDEBUG__
        std::stringstream ss;
        ss << WSAGetLastError();
        MessageBox(NULL, ss.str().c_str(), "", MB_ICONERROR | MB_OK);
#endif
        return Inc::ERECV;
    }...
