<p>It can be created by making a connection using a <a class="el" href="classwx_d_d_e_client.html" title="A wxDDEClient object represents the client part of a client-server DDE (Dynamic Data Exchange) conver...">wxDDEClient</a> object, or by the acceptance of a connection by a <a class="el" href="classwx_d_d_e_server.html" title="A wxDDEServer object represents the server part of a client-server DDE (Dynamic Data Exchange) conver...">wxDDEServer</a> object. The bulk of a DDE (Dynamic Data Exchange) conversation is controlled by calling members in a <a class="el" href="classwx_d_d_e_connection.html" title="A wxDDEConnection object represents the connection between a client and a server.">wxDDEConnection</a> object or by overriding its members.</p>
<p>An application should normally derive a new connection class from <a class="el" href="classwx_d_d_e_connection.html" title="A wxDDEConnection object represents the connection between a client and a server.">wxDDEConnection</a>, in order to override the communication event handlers to do something interesting.</p>
<p>This DDE-based implementation is available on Windows only, but a platform-independent, socket-based version of this API is available using <a class="el" href="classwx_t_c_p_connection.html" title="A wxTCPClient object represents the connection between a client and a server.">wxTCPConnection</a>.</p>
