Hello all
I'm using a bit of very simple code to query a game server using a UDP
packet. It works the fine time I run it but then when I run it again straight
away it fails with..
"A message sent on a datagram socket was larger than the internal message
buffer or some other network limit, or the buffer used to receive a datagram
into was smaller than the datagram itself"
I reckon it's because the socket is not closing properly so is dtill open
when I run it a second time. I assume this is down to lingeroption but I
can't seem to set this to false as the syntax on msdn doesn't seem to work.
Could someeone give me a hand with this please? My code is below...
'SERVER QUERY
Dim A2S_SERVERQUERY_GETCHALLENGE() As Byte = {&HFF, &HFF, &HFF,
&HFF, &H57}
'DECLARE ENDPOINTS
Dim localIPEndPoint As IPEndPoint = New IPEndPoint(0, 0)
Dim remoteIPEndPoint As IPEndPoint = New
IPEndPoint(IPAddress.Parse("192.168.0.6"), 27015)
Dim remoteEndPoint As EndPoint = CType(remoteIPEndPoint, EndPoint)
Dim s As Socket = New Socket(AddressFamily.InterNetwork,
SocketType.Dgram, ProtocolType.Udp)
'BIND TO LOCAL PORT
s.Bind(localIPEndPoint)
'SET SOCKET TIMEOUT TO 1 SECOND
s.SetSocketOption(SocketOptionLevel.Socket,
SocketOptionName.ReceiveTimeout, 1000)
'SEND QUERY STRING
s.SendTo(A2S_SERVERQUERY_GETCHALLENGE, remoteEndPoint)
Dim return_bytes(s.Available) As Byte
s.Receive(return_bytes, 0, s.Available, 0)
'CLOSE SOCKET
s.Close()
