A wxDDEClient object represents the client part of a client-server DDE (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 so that a user-overridden OnMakeConnection() member can return 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 wxTCPClient.

|wxConnectionBase *||MakeConnection (const wxString &host, const wxString &service, const wxString &topic)|

|wxConnectionBase* wxDDEClient::MakeConnection||(||const wxString &||host,|
|const wxString &||service,|
|const wxString &||topic|
Tries to make a connection with a server specified by the host (machine name under UNIX, ignored under Windows), service name (must contain an integer port number under UNIX), and topic string.
If the server allows a connection, a wxDDEConnection object will be returned.
By default, a wxDDEConnection object is returned.
The advantage of deriving your own connection class is that it will enable you to intercept messages initiated by the server, such as wxDDEConnection::OnAdvise(). You may also want to store application-specific data in instances of the new class.
|bool wxDDEClient::ValidHost||(||const wxString &||host||)|
Returns true if this is a valid host name, false otherwise.
This always returns true under MS Windows.
