Hi all, I'm writing a UDP program and I'd like to have the socket time out if it doesn't recieve an answer in n milliseconds.
What I do is send a packet to a UDP server, which is fine, everything works ok... but then I want to wait n milliseconds for a reply, and if I don't get a reply then handle accordingly. However, with my current code, my code hangs if I don't get a reply back from the server. Does anyone know what I need to change? Here is my code... //sending the packet, works great! byte[] PacketToSend = BuildPacket(); IPAddress address = Dns.Resolve( serverAddress ).AddressList[0]; Socket s = new Socket( AddressFamily.InterNetwork,SocketType.Dgram,ProtocolType.Udp); s.SendTo( PacketToSend, 0, PacketToSend.Length, SocketFlags.None, new IPEndPoint( address, _Port ) ); //works great if the packet comes back, but //hangs up if the response packet is never rec'd m_UdpPacket = new Byte[ m_Length ]; IPEndPoint sender = new IPEndPoint(IPAddress.Any, 0); EndPoint tempRemoteEP = (EndPoint)sender; s.ReceiveFrom( m_UdpPacket, 0, m_Length , SocketFlags.None, ref tempRemoteEP ); Thanks in advance, Dave You can read messages from the DOTNET archive, unsubscribe from DOTNET, or subscribe to other DevelopMentor lists at http://discuss.develop.com.
