Further information on these classes will be available in due course.
Notice that by including {\tt <wx/ipc.h>} you may define convnient synonyms for
the IPC classes: {\tt wxServer} for either {\tt wxDDEServer} or
{\tt wxTCPServer} depending on whether DDE-based or socket-based implementation
is used and the same thing for {\tt wxClient} and {\tt wxConnection}. By
default, DDE implementation is used under Windows. If you want to use IPC
between the different workstations you should define {\tt wxUSE\_DDE\_FOR\_IPC}
as $0$ before including this header -- this will force using TCP/IP
implementation even under Windows.
wxWindows has a high-level protocol based on Windows DDE.
There are two implementations of this DDE-like protocol:
one using real DDE running on Windows only, and another using TCP/IP (sockets) that runs
