ROUTINE DESCRIPTION:
    This routines handles the 're-routed' window posted command messages. The general DataIo (DCOM)
    routines that we use would normally call the PostMessage() routine to handle incoming data requests.
    But for console applications, there is NO windows application to handle the PostMessage() commands,
    so in DataIo.cpp (SetData() routine), it was modified to call a locally define PostMessageConsole()
    routine instead if the user defines "ConsoleApplication" at build time.
  
GLOBAL DATA:
    None

INPUT:
    hWnd   - Handle to the window - always NULL
    uMsg   - The message.
    wParam - The word parameter for the message.
    lParam - the long parameter for the message.

    Note: These are the same inputs that the WndProc() routine would handle for PostMessage() commands.

RETURN:
    TRUE
