A wxDDEClient object represents the client part of a client-server DDE
-(Dynamic Data Exchange) conversation (available in {\it both}\/
-Windows and UNIX).
+(Dynamic Data Exchange) conversation.
To create a client which can communicate with a suitable server,
you need to derive a class from wxDDEConnection and another from wxDDEClient.
The custom wxDDEConnection class will intercept communications in
a `conversation' with a server, and the custom wxDDEServer is required

a wxDDEConnection of the required class, when a connection is made.
+This DDE-based implementation is
+available on Windows only, but a platform-independent, socket-based version
+of this API is available using \helpref{wxTCPClient}{wxtcpclient}.

The type of \helpref{wxDDEConnection}{wxddeconnection} returned from a \helpref{wxDDEClient::MakeConnection}{wxddeclientmakeconnection} call can
