A 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.
wxTCPServer, wxTCPConnection, Interprocess communications overview
Constructs a client object.
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.
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.
Returns true if this is a valid host name, false otherwise.ymasuda 平成17年11月19日
