A wxConnection object represents the connection between a client
and a server. It is created by making a connection using a\rtfsp
-\helpref{wxClient}{wxddeclient} object, or by the acceptance of a
-connection by a\rtfsp \helpref{wxServer}{wxddeserver} object. The

+connection by a\rtfsp \helpref{wxServer}{wxserver} object. The
bulk of a DDE-like (Dynamic Data Exchange) conversation is
controlled by calling members in a {\bf wxConnection} object or
by overriding its members. The actual DDE-based implementation
