Kommastreg

Her er lige lidt nørderi.

På mit job har jeg udviklet følgende Java kode, som kommunikerer med et Projekter tilsluttet et lokalt netværk. Da der ikke var andet tilsvarende at finde på nettet, har jeg hermed valgt at tilgængelig gøre koden her på nettet.

* Remember to update line “pjLinkSocket = new Socket(”172.20.X.X”, 4352);” with the correct IP-Address
* Only works on Projector without Password. Haven’t implemented the md5 authentication.

package pjLink;

import java.io.BufferedReader;
import java.io.DataOutputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.Socket;
import java.net.UnknownHostException;

import pjLink.Projector.*;

Kan du bruge det, så god fornøjelse
