wxConnection * OnAcceptConnection(char *topic)
When a client calls MakeConnection, the server receives the message and this member is called. The application should derive a member to intercept this message and return a connection object of either the standard wxConnection type, or of a user-derived type. If the topic is "STDIO'', the application may wish to refuse the connection. Under UNIX, when a server is created the OnAcceptConnection message is always sent for standard input and output, but in the context of DDE messages it doesn't make a lot of sense.
