Saving

I was wondering how you can save two messages from the server in two different variables on the arduino?

THANKS!

You seem to be missing quite a lot of information from your question. Care to try again?

My question was this!

#include <SPI.h>
#include <Ethernet.h>

byte mac[] = { 0x90, 0xA2, 0xDA, 0x0F, 0x50, 0x35 };

IPAddress arduino(192,168,0,12);
IPAddress server(192,168,0,15);

EthernetClient client;

String username[] = {"Admin","Skut","Arbek","Kubda"};
String password[] = {"12344","stra","124ssgra","!#¤%"};

void setup() {
Serial.begin(9600);
Ethernet.begin(mac,arduino);
Serial.println("Connecting...");
if (client.connect(server, 8888)){
Serial.println("Connected to Server");
} else {
Serial.println("Connecting failed");
}
}

boolean verify(){
for(int i = 0; i < 4 ; i++){
if((username == "Admein") && (password == "12344")){
* return true;*
* }*
* }*
* return false;*
}
void loop(){
* if (client.available()){*
* char c[2];*
* for(int i = 0; i < 2 ; i++){*
_ c = client.read();
* Serial.print(c[1]);
 //Serial.print(c[2]);
 }
}*_

if (!client.connected()){
* Serial.println();*
* client.stop();*

* while(true);*
}
}
The question is! How can you save a username and a password sent from the server in two different variables o the arduino?

THis bit of "code" you posted :

if((username == "Admein") && (password == "12344")){
return true;

will not work. But you probably wrote

    if((username[i] == "Admein") && (password[i] == "12344")){
     return true;

which is why you MUST USE THE [code] [/code] tags around code so [i] shows instead of turning on italics.

until then it is too hard to read your code.

Could you go through the steps of what your program is doing? The logic of it? I personally don't understand the for loop.

Hello!

This is the new code! Hope you understand it this time!

#include <SPI.h>
#include <Ethernet.h>

byte mac[] = { 0x90, 0xA2, 0xDA, 0x0F, 0x50, 0x35 };

IPAddress arduino(192,168,0,50);
IPAddress server(192,168,0,15);

EthernetClient client;

String username[] = {"Admin","Skut","Arbek","Kubda"};
String password[] = {"12344","stra","124ssgra","!#¤%"};

String readString;

void setup() {
  Serial.begin(9600);
  Ethernet.begin(mac,arduino);
  Serial.println("Connecting...");
  if (client.connect(server, 8888)){
   Serial.println("Connected to Server");
  } else {
    Serial.println("Connecting failed");
  }
}

void clientRead() { 
  while (client.available()) {
  //delay(10);  
    if (client.available() >0) {
      char c = client.read();
      readString += c;
    }
}
}

boolean verify(String firstText, String secondText){
  for(int i = 0; i <= 3 ; i++){
    if((firstText.equals(username[i])) && (secondText.equals(password[i]))){ 
      return true; 
    }
  }
    return false;
   }

void loop(){
  if (client.available() > 0){
    readString = "";
    clientRead();
    int n = readString.length();
    int commaIndex = readString.indexOf(';');
    int lastIndex = readString.lastIndexOf(n);
    String firstText = readString.substring(0, commaIndex);
    String secondText = readString.substring(commaIndex + 1 , lastIndex);
    Serial.println(firstText);
    Serial.println(secondText);
    Serial.println(verify(firstText, secondText));
  }

 if (!client.connected()){
   Serial.println("Server disconnected!");
   client.stop();
   client.flush();
   while(true);
 }
}

Describing the detailed steps of the program in plain language (rather than computer code) is a great way to discover errors and uncertainties in the logic.
