ControlChannelTrigger and WinSock RRS feed

  • Question

  • Hi,

    We have a large code base which uses WinSock calls and these appear to be available to runtime apps (as highlighted here: http://msdn.microsoft.com/en-us/library/windows/apps/dn424765.aspx).  Great news.

    However we also would like our app to have a long-lived network connection so I've been looking into using ControlChannelTrigger.  This would appear to be what we want to talk to a legacy server, albeit with the requirement that the user approves our app for the lock screen.

    So is it possible to use ControlChannelTrigger and old-style sockets? ControlChannelTrigger only appears to take StreamSockets or IXMLHTTPRequest (our socket communication isn't HTTP based).

    If not has anyone else solved this issue?

    All help greatly appreciated.

  • No, you cannot use winsock API with ControlChannelTrigger. In fact, you can only use the Windows Runtime Networking API that is available in the Windows.Networking.Sockets namespace. For example: StreamSocket for TCP Socket and DatagramSocket for UDP socket.

    The Desktop Winsock functionality cannot be used in Windows Runtime apps. See the documentation for socket/connect/send/recv/closesocket and notice that it says "Desktop apps only"
