   2
   3 A wxDDEServer object represents the server part of a client-server DDE
   4 (Dynamic Data Exchange) conversation.
   5
   6 This DDE-based implementation is
   7 available on Windows only, but a platform-independent, socket-based version
   8 of this API is available using \helpref{wxTCPServer}{wxtcpserver}.

  32 \func{bool}{Create}{\param{const wxString\& }{service}}
  33
  34 Registers the server using the given service name. Under UNIX, the
  35 string must contain an integer id which is used as an Internet port
  36 number. false is returned if the call failed (for example, the port
  37 number is already in use).

  41 \func{virtual wxConnectionBase *}{OnAcceptConnection}{\param{const wxString\& }{topic}}
  42
  43 When a client calls {\bf MakeConnection}, the server receives the
  44 message and this member is called. The application should derive a
  45 member to intercept this message and return a connection object of
  46 either the standard wxDDEConnection type, or of a user-derived type. If the
  47 topic is ``STDIO'', the application may wish to refuse the connection.
  48 Under UNIX, when a server is created the OnAcceptConnection message is
  49 always sent for standard input and output, but in the context of DDE
  50 messages it doesn't make a lot of sense.
