Mini Messenger

[Ikerkaz]

And, here's a version posted by Zeppelin which combines both utilities into one:

Code: (Select All)

DIM SHARED Users(1 TO 1000) ' array to hold other client info
DIM SHARED NumClients
DIM SHARED OUT$


PRINT "[Steve's Mini Messenger]"
host = _OPENHOST("TCP/IP:7319") ' no host found, so begin new host
IF host THEN
    PRINT "[Beginning new host chat session!]"
    NumClients = 0
    client = _OPENCLIENT("TCP/IP:7319:localhost")
    IF client = 0 THEN PRINT "ERROR: could not attach host's personal client to host!"
    INPUT "Enter your name:", myname$
    'PRINT #client, myname$ + " connected!"
    PRINT "[Chat session active!]"
ELSE
    PRINT "ERROR: Could not begin new host!"
    PRINT "JOINING as CLIENT"

    'Join as client
    client = _OPENCLIENT("TCP/IP:7319:localhost") ' Attempt to connect to local host as a client
END IF ' host

IF host THEN
    _TITLE "HOST"
    DO ' host main loop
        newclient = _OPENCONNECTION(host) ' receive any new connection
        IF newclient THEN
            NumClients = NumClients + 1
            Users(NumClients) = newclient
            PRINT "Welcome to Steve's Mini Messenger!"
        END IF
        FOR i = 1 TO NumClients
            GetMessage Users(i) 'check all clients for a message
            IF OUT$ <> "" THEN
                l = LEN(OUT$)
                FOR j = 1 TO NumClients ' distribute incoming messages to all clients
                    PUT #Users(j), , l
                    PUT #Users(j), , OUT$
                NEXT
            END IF
        NEXT i

        SendMessage myname$, mymessage$, client
        _LIMIT 30
    LOOP
END IF

IF client THEN
    INPUT "Enter your name: ", myname$
    OUT$ = myname$ + " connected!"
    l = LEN(OUT$)
    PUT #client, , l
    PUT #client, , OUT$

    _TITLE "CLIENT"

        OUT$ = ""
    END IF
END SUB

    k$ = INKEY$

        ELSE

        END IF
    END IF

Hello, I'm trying to run this program on two computers in my own house, but it does not work.
I tried to change the line TCP/IP:7319:localhost and I tried 8080:192.168.1.23 (the host's IP) but it is useless.

What am I doing wrong?

Thank you very much.
