Hi All,

I am having a problem writing a a simpe IP packet sniffer for Windows
Mobile 5. I have taken a simple piece of code that works fine on the
standard framework but when I run under CF 2.0 I get compilation
errors in relation to the IOControlCode enum which the compact
framework does not recognise. I get an error "The name 'IOControlCode'
does not exist in the current context" I'm assuming raw socket
capturing is supported in CF 2.0. Does anyone know what the enum value
should be as CF expects an int but i tried the int -1744830463 which i
found on the MSDN website but this fails.

//For sniffing the socket to capture the packets has to be a raw
socket, with the
//address family being of type internetwork, and protocol being IP
mainSocket = new Socket(AddressFamily.InterNetwork,
SocketType.Raw, ProtocolType.IP);

//Bind the socket to the selected IP address
mainSocket.Bind(new IPEndPoint(IPAddress.Parse(cmbInterfaces.Text),
0));

//Set the socket  options
mainSocket.SetSocketOption(SocketOptionLevel.IP,            //Applies
only to IP packets
                                  SocketOptionName.HeaderIncluded, //
Set the include the header
                                  true);                           //
option to true

                   byte[] byTrue = new byte[4] { 1, 0, 0, 0 };
                   byte[] byOut = new byte[4];

//Socket.IOControl is analogous to the WSAIoctl method of Winsock 2
mainSocket.IOControl(IOControlCode.ReceiveAll,     //THIS LINE
FAILS
                                       byTrue,
                                        byOut);

//Start receiving the packets asynchronously
mainSocket.BeginReceive(byteData, 0, byteData.Length,
SocketFlags.None,
                       new AsyncCallback(OnReceive), null);

Hope you can help,
