I''m using MFC''s CAsyncSocket (no flames please), but you should get the idea from the code snippet what I''m doing. This code fails. It tells me I passed an invalid parameter to Bind(). Incidentally, CAsyncSocket::Create() calls Bind() on the port it''s passed. This is called in the constructor of a class inherited from CAsyncSocket. if(!CAsyncSocket::Create(m_iPort, SOCK_DGRAM)) ShowLastError(); BOOL b = TRUE; if(!SetSockOpt(SO_BROADCAST, &b, sizeof(b))) ShowLastError(); sockaddr_in sin; ZeroMemory(&sin, sizeof(sin)); sin.sin_family = AF_INET; sin.sin_port = m_iPort; sin.sin_addr.s_addr = INADDR_ANY; if(!CAsyncSocket::Bind((SOCKADDR*)&sin, sizeof(sin))) ShowLastError();//Says "Invalid parameter" This socket would be used to receive datagram broadcasts on m_iPort, if only it would work. How do you receive datagram broadcasts? A google newsgroups search returns dozens of long threads about how to do it, but none of them work, and they''re all different... Thanks, ~BenDilts( void );
