jeg har siddet lidt og prøvet sidens prøver og er kommet til level4 – og nu kan jeg ikke komme videre – jeg er dog stødt på dette stykke java-kode:
import java.applet.Applet;
import java.applet.AppletContext;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.*;
import java.net.MalformedURLException;
import java.net.URL;
import java.util.EventObject;public class PasswdLevel4 extends Applet
implements ActionListener {private URL finalurl;
String infile;
String inuser[];
int totno;
InputStream countConn;
BufferedReader countData;
URL inURL;
TextField txtlogin;
Label label1;
Label label2;
Label label3;
TextField txtpass;
Label lblstatus;
Button ButOk;
Button ButReset;
Label lbltitle;public PasswdLevel4() {
inuser = new String[22];
totno = 0;
countConn = null;
countData = null;
inURL = null;
txtlogin = new TextField();
label1 = new Label();
label2 = new Label();
label3 = new Label();
txtpass = new TextField();
lblstatus = new Label();
ButOk = new Button();
ButReset = new Button();
lbltitle = new Label();
}void ButOk_ActionPerformed(ActionEvent actionevent) {
boolean flag = false;
for(int i = 1; i <= totno / 2; i++) if(txtlogin.getText().trim().toUpperCase().intern() == inuser[2 * (i - 1) + 2].trim().toUpperCase().intern() && txtpass.getText().trim().toUpperCase().intern() == inuser[2 * (i - 1) + 3].trim().toUpperCase().intern()) { lblstatus.setText("Login Success, Loading.."); flag = true; String s = inuser[1].trim().intern(); String s1 = getParameter("targetframe"); if(s1 == null) s1 = "_self"; try { finalurl = new URL(getCodeBase(), s); } catch(MalformedURLException _ex) { lblstatus.setText("Bad URL"); } getAppletContext().showDocument(finalurl, s1); }if(!flag) lblstatus.setText("Invaild Login or Password"); }void ButReset_ActionPerformed(ActionEvent actionevent) { txtlogin.setText(""); txtpass.setText(""); }public void actionPerformed(ActionEvent actionevent) { Object obj = actionevent.getSource(); if(obj == ButOk) { ButOk_ActionPerformed(actionevent); return; } if(obj == ButReset) ButReset_ActionPerformed(actionevent); }public void destroy() { ButOk.setEnabled(false); ButReset.setEnabled(false); txtlogin.setVisible(false); txtpass.setVisible(false); }public void inFile() { new StringBuffer(); try { countConn = inURL.openStream(); countData = new BufferedReader(new InputStreamReader(countConn)); String s; while((s = countData.readLine()) != null) if(totno < 21) { totno = totno + 1; inuser[totno] = s; s = ""; } else { lblstatus.setText("Cannot Exceed 10 users, Applet fail start!"); destroy(); } } catch(IOException ioexception) { getAppletContext().showStatus("IO Error:" + ioexception.getMessage()); } try { countConn.close(); countData.close(); return; } catch(IOException ioexception1) { getAppletContext().showStatus("IO Error:" + ioexception1.getMessage()); } }public void init() { setLayout(null); setSize(361, 191); add(txtlogin); txtlogin.setBounds(156, 72, 132, 24); label1.setText("Please Enter Login Name & Password"); label1.setAlignment(1); add(label1); label1.setFont(new Font("Dialog", 1, 12)); label1.setBounds(41, 36, 280, 24); label2.setText("Login"); add(label2); label2.setFont(new Font("Dialog", 1, 12)); label2.setBounds(75, 72, 36, 24); label3.setText("Password"); add(label3); add(txtpass); txtpass.setEchoChar('*'); txtpass.setBounds(156, 108, 132, 24); lblstatus.setAlignment(1); label3.setFont(new Font("Dialog", 1, 12)); label3.setBounds(75, 108, 57, 21); add(lblstatus); lblstatus.setFont(new Font("Dialog", 1, 12)); lblstatus.setBounds(14, 132, 344, 24); ButOk.setLabel("OK"); add(ButOk); ButOk.setFont(new Font("Dialog", 1, 12)); ButOk.setBounds(105, 156, 59, 23); ButReset.setLabel("Reset"); add(ButReset); ButReset.setFont(new Font("Dialog", 1, 12)); ButReset.setBounds(204, 156, 59, 23); lbltitle.setAlignment(1); add(lbltitle); lbltitle.setFont(new Font("Dialog", 1, 12)); lbltitle.setBounds(12, 14, 336, 24); String s = getParameter("title"); lbltitle.setText(s); ButOk.addActionListener(this); ButReset.addActionListener(this); infile = new String("level4"); try { inURL = new URL(getCodeBase(), infile); } catch(MalformedURLException _ex) { getAppletContext().showStatus("Bad Counter URL:" + inURL); } inFile(); } }siger det nogen noget om hvad 'login' og 'password' er? eller ligger det måske i en helt anden kode?jeg er farlig...BUM !!!!
