2
3A wxTCPClient object represents the client part of a client-server conversation.
4It emulates a DDE-style protocol, but uses TCP/IP which is available on most platforms.
5
6A DDE-based implementation for Windows is available using \helpref{wxDDEClient}{wxddeclient}.
7
8To create a client which can communicate with a suitable server,
9you need to derive a class from wxTCPConnection and another from wxTCPClient.
10The custom wxTCPConnection class will intercept communications in
11a `conversation' with a server, and the custom wxTCPServer is required
12so that a user-overridden \helpref{wxTCPClient::OnMakeConnection}{wxtcpclientonmakeconnection} member can return
13a wxTCPConnection of the required class, when a connection is made.

37\func{}{wxTCPClient}{\void}
38
39Constructs a client object.

42
43\func{wxConnectionBase *}{MakeConnection}{\param{const wxString\& }{host}, \param{const wxString\& }{service}, \param{const wxString\& }{topic}}
44
45Tries to make a connection with a server specified by the host
46(a machine name under Unix), service name (must
47contain an integer port number under Unix), and a topic string. If the
48server allows a connection, a wxTCPConnection object will be returned.
49The type of wxTCPConnection returned can be altered by overriding
50the \helpref{wxTCPClient::OnMakeConnection}{wxtcpclientonmakeconnection} member to return your own
51derived connection object.

54
55\func{wxConnectionBase *}{OnMakeConnection}{\void}
56
57The type of \helpref{wxTCPConnection}{wxtcpconnection} returned from a \helpref{wxTCPClient::MakeConnection}{wxtcpclientmakeconnection} call can
58be altered by deriving the {\bf OnMakeConnection} member to return your
59own derived connection object. By default, a wxTCPConnection
60object is returned.
61
62The advantage of deriving your own connection class is that it will
63enable you to intercept messages initiated by the server, such
64as \helpref{wxTCPConnection::OnAdvise}{wxtcpconnectiononadvise}. You may also want to
65store application-specific data in instances of the new class.

67\membersection{wxTCPClient::ValidHost}\label{wxtcpclientvalidhost}
68
69\func{bool}{ValidHost}{\param{const wxString\& }{host}}
70
71Returns true if this is a valid host name, false otherwise.
