Ethernet Shield error

I am using below Open source Code to test my Ethernet sheild connected to Uno . Seems Everything is fine but when I try to compile or upload its comming up with error ; 'Ethernet has not been declared' and There are few other error probally causing because of the Main error ;

rbbb_server:11: error: 'Ethernet' has not been declared

rbbb_server:12: error: 'BufferFiller' does not name a type

rbbb_server.ino: In function 'void setup()':

rbbb_server:15: error: 'ether' was not declared in this scope

rbbb_server:15: error: 'Ethernet' has not been declared

rbbb_server:17: error: 'ether' was not declared in this scope

rbbb_server.ino: In function 'word homePage()':

rbbb_server:25: error: 'bfill' was not declared in this scope

rbbb_server:25: error: 'ether' was not declared in this scope

rbbb_server.ino: In function 'void loop()':

rbbb_server:39: error: 'ether' was not declared in this scope.

if someone can help me fix this issues it will be grateful Thank you

And to prove the new ENC library is code comparable with the Wiznet library here is the same sketch working on the ENC chip, the ONLY difference was which library I included

Thank you very much sir. Really appreciate your help. I would like you to help me if possible with this code below, Will it work with Wiznet ethernet module ? it works fine on ENC chip module.

// DHT code from:
// Example testing sketch for various DHT humidity/temperature sensors
// Written by ladyada, public domain

#include "DHT.h"

#define DHTPIN 2     // what pin we're connected to

// Uncomment whatever type you're using!
#define DHTTYPE DHT11   // DHT 11
// #define DHTTYPE DHT22   // DHT 22 (AM2302)
//#define DHTTYPE DHT21   // DHT 21 (AM2301)
DHT dht(DHTPIN, DHTTYPE);

// LCD
// LCD RS=3, EN=4, DS4=5, DS5=6, DS6=7, DS7=8
#include Humidity: $D %
"),
t, h);
return bfill.position();
}

// The main loop
// We add to the timer and read the DHT11 values when Timer == 1, otherwise we loop without reading it
// Once the Timer value == to 1100 we zero it and start the count again. This way the sensors are only
// read once every 1100 loops. Every time we go through the loop we listen for a request on the Ethernet
// If we see one we send the webpage. We also add an animation on the LCD so we know the loop is working.

void loop () {

Timer = Timer+1;
if(Timer==1)
{
    ReadDHT11();
    // set the cursor to (0,0):
    lcd.setCursor(0, 0);
    // print from 0 to 9:

    lcd.print("Temp: ");
    lcd.print(t);
    lcd.print("C");
    // set the cursor to (16,1):
    lcd.setCursor(0,1);
    lcd.print("Humidity: ");
    lcd.print(h);
    lcd.print("%");

    if(Animation==0)
    {
      lcd.print(" *");
    }
    if(Animation==1)
    {
      lcd.print(" +");
    }
    Animation = Animation + 1;
    if(Animation==2)
    {
      Animation=0;
    }
}
if(Timer==1100)a
{
    Timer=0;
}

word len = ether.packetReceive();
word pos = ether.packetLoop(len);

if (pos) // check if valid tcp data is received

I think this will answer your question

DHT22 temperature and Humidity Sensor with Arduino Uno and Ethernet Card (ENC or WizNet) (Instant weather Station)

I posted this last night, all you need to do is incorporate the LCD bits of code and your done. It will work with the ENC or WIZ, just change the include statement

This is the code below you suggested but need to add LCD code bit ! I have no qlue what to do .. I am kind of Stuck! ( I am using It with Wiznet Based Ethernet Sheild)
