wxTCPClientA wxTCPClient object represents the client part of a client-server conversation. It emulates a DDE-style protocol, but uses TCP/IP which is available on most platforms. A DDE-based implementation for Windows is available using wxDDEClient. To create a client which can communicate with a suitable server, you need to derive a class from wxTCPConnection and another from wxTCPClient. The custom wxTCPConnection class will intercept communications in a 'conversation' with a server, and the custom wxTCPServer is required so that a user-overridden wxTCPClient::OnMakeConnection member can return a wxTCPConnection of the required class, when a connection is made.

wxTCPClient::wxTCPClient
wxTCPClient::wxTCPClientwxTCPClient() Constructs a client object.
wxTCPClient::MakeConnectionwxConnectionBase * MakeConnection(const wxString& host, const wxString& service, const wxString& topic) Tries to make a connection with a server specified by the host (a machine name under Unix), service name (must contain an integer port number under Unix), and a topic string. If the server allows a connection, a wxTCPConnection object will be returned. The type of wxTCPConnection returned can be altered by overriding the wxTCPClient::OnMakeConnection member to return your own derived connection object.
wxTCPClient::OnMakeConnectionwxConnectionBase * OnMakeConnection() The type of wxTCPConnection returned from a wxTCPClient::MakeConnection call can be altered by deriving the OnMakeConnection member to return your own derived connection object. By default, a wxTCPConnection 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 wxTCPConnection::OnAdvise. You may also want to store application-specific data in instances of the new class.
wxTCPClient::ValidHostbool ValidHost(const wxString& host) Returns true if this is a valid host name, false otherwise.
