Interface with DatagramSocket
|
|
http://msdn.microsoft.com/en-us/library/windows/apps/windows.networking.sockets.datagramsocket
|
|
|
|
Set the event handler
|
|
http://msdn.microsoft.com/en-us/library/windows/apps/windows.networking.sockets.datagramsocket.messagereceived
|
|
|
|
Then bind (asynch):
|
|
http://msdn.microsoft.com/en-us/library/windows/apps/windows.networking.sockets.datagramsocket.bindendpointasync
|
|
|
|
Close socket:
|
|
http://msdn.microsoft.com/en-us/library/windows/apps/windows.networking.sockets.datagramsocket.close
|
|
|
|
SystemAddress to / from IPV4, IPV6
|
|
|
|
Domain name to IP lookup
|
|
|
|
Lots of info here:
|
|
Do not use ConnectAsynch, because you cannot get datagrams from any remote address, only those you have connected to.

|
|
Send:
|
|
When sending to a new system, use GetOuputStreamAsynch http://msdn.microsoft.com/en-us/library/windows/apps/hh701265. When it completes, send the data using
|
|
DataWriter http://msdn.microsoft.com/en-us/library/windows/apps/windows.storage.streams.datawriter.aspx
|
|
Use WriteBuffer, then StoreAsynch.
|
|
|
|
http://msdn.microsoft.com/en-us/library/windows/apps/hh701265
|
|
For each connection, need GetOutputStreamAsync, which specifies a hostname (IP address) and port.
|
|
|
|
Set TTL:
|
|
Use control:
|
|

|
|
|
|
Receive:
|
|
http://msdn.microsoft.com/en-us/library/windows/apps/BR241344
|
|
DatagramSocket^ listener = ref new DatagramSocket();
|
|
ListenerContext^ listenerContext = ref new ListenerContext(rootPage, listener);
|
|
listener->MessageReceived += ref new TypedEventHandler<DatagramSocket^, DatagramSocketMessageReceivedEventArgs^>(listenerContext, &ListenerContext::OnMessage);

How to callback to existing C++ from C++/CX?
|
|
|
|
I have a large body of C++ code that I am trying to integrate with Windows 8 Store. In the existing code, I use a pure virtual interface for when a network message arrives
|
|
class RNS2EventHandler {
|
|
virtual void OnRNS2Recv(RNS2RecvStruct *recvStruct)=0;
|
|
};
|
|
class RakPeer : public RakPeerInterface, public RNS2EventHandler {
|
|
virtual void OnRNS2Recv(RNS2RecvStruct *recvStruct) {DoStuff();}
|
|
};
|
|
|
|
In Windows Store 8, I get this callback when a network message arrives
|
|
public ref class ListenerContext sealed
|
|
{
|
|
public:
|
|
void OnMessage(Windows::Networking::Sockets::DatagramSocket^ socket, Windows::Networking::Sockets::DatagramSocketMessageReceivedEventArgs^ eventArguments) {
|
|
// Need to call the C++ callback
|
|
}
|
|
}
|
|
|
|
If I try putting a RNS2EventHandler* inside ListenerContext the compiler complains that I can't put C++ types inside a C++/CX class.
|
|
|
|
So how do I implement a callback to notify C++ when ListenerContext::OnMessage occurs? As a last resort I can poll ListenerContext in a thread from the C++ code, but that ruins performance and the whole point of a callback. But I'll do it if there is no straightforward alternative.

Thanks in advance.
