Java Applet out displaying incorrectly

• Java applet to draw the grid

  Hi, I have an exam Tuesday and an assignment Ive done before is to draw a checkerboard, but one last question was to draw a grid with horizontal red and blue lines vertical.
  
  It should display a dialog box of entry asking the user how many lines to draw along each side and the boss should size itself to fit exactly to the applet area.
  
  He is said to use setColor (Color c) and fillRect(x1,y1,x2,y2): draws lines between (x 1, y1) and (x 2, y2)
  
  Here is my code for the chessboard:
  

  import java.awt.*;
  import java.applet.*;
  
  public class Q2_chessboard extends Applet {
       public void paint(Graphics g) 
       {
  
            int row, column, x, y;
            
            //for every row on the board
            for (row = 0;  row < 8;  row++ ) 
            {
                 //for every column on the board
                 for (column = 0;  column < 8;  column++) 
                 {
                      //Coordinates
                      x = column * 20;
                      y = row * 20;
                      
                      //square is red if row and col are either both even or both odd.
                      if ( (row % 2) == (column % 2) ) 
                           g.setColor(Color.red);
                      
                      else
                           g.setColor(Color.black);
                      g.fillRect(x, y, 20, 20);
                 } 
            } 
       }
  }

  But Ive tried for centuries and cannot make this code the code required for the last question.
  
  I know I should use:

            //Gets size of Applet
            int appletHeight = getSize().height;
            int appletWidth = getSize().width;

  But can't wrap our heads around him to use it.
  
  I had replaced the numeric values of the row and column with

            input = JOptionPane.showInputDialog("Enter number lines to draw on each side:");
            lines = Integer.parseInt(input);

  but he came twice asked and I couldn't develop the applet without him asking again for entry.

  (1) do not mix AWT and Swing - JApplet use if you want to use JOptionPane
  (2) do not apply input inside paint and paintComponent methods. You can't control when this method is called and it should not change the State, only the paint as soon as possible.
  (3) not to replace the painting of a JApplet rather add a JPanel with a paintComponent method overridden to the content pane. A search on 'java custom paint tutorial' for more information.
  (4) for the right way to code a JApplet search «java JApplet tutorial» You option pane should be shown in the called in the init() (on the EDT) method. The result is best set as an instance variable of the Panel that made the paint.
  (5) two loops sounds great, but you can move the color out of her statement.

• When I type in my Thunderbird email all characters are displayed correctly, but in Firefox characters are displayed incorrectly.

  When I type in my Thunderbird email all the characters appear correctly. When I type in a web site using Firefox or Chrome the characters are displayed incorrectly.

• How can I stop Firefox from blocking a Java applet on a website that I trust?

  I'm trying to run an application that displays the competing routes during an orienteering event. My problem is that Firefox is blocking the Java applet. I get a window saying "blocked by security settings Application. Your security settings have blocked an app to run with a precarious jre or has expired. »

  I tried to look at the Firefox Help on "How to enable Java if it's been blocked", but it does not help. He's talking about by clicking on the Red plugin icon in the address bar, but it is not a plugin red icon in the address bar.

  The application is www.epoc.routegadget.co.uk. It worked when I used it last Sunday.

• Some Java applets do not work after the installation in silent mode, resolved in tilting head "enable Java content in the browser" - why?

  We have about 1 800 workstations with Windows 7 (32-bit and 64-bit) running different versions of JRE Java 6 update via update 7 51 32.  Most are on 6 45 update.  We would like to standardize on update of Java 7 51 (32-bit) and get everyone updated to this version for security reasons.

  For the last two weeks, we had trouble with our driver prior to installation.  What we are seeing, it of that our procedure successfully closed all open Internet Explorer Windows and processes related to Java, uninstall all older versions of JRE Java and says then successfully installed of the update of Java 7 51.  The Java Control Panel works.  We can even take Internet Explorer to check the Java Version or Java Tester - what Version of Java are you running? and confirm that the Java applets on these sites load (although the latter only works after adding the site to the list of site exceptions); However, when the testers try to access our system Kronos Workforce Central 6.3.10, used by this system Java applets do not load.

  We tried the following things, which none worked:

  • Empty the Internet Explorer browser cache and cookies.
  • Clear the local Java cache.
  • Restart the computer.
  • Reset Internet Explorer settings, including personal settings.

  Go to the Panel control Java, ranging in the Security tab, uncheck "enable Java in the browser content", the only thing that works based on apply, press OK in the pop-up window, checking the box "Enable Java in the browser content", press OK, press OK in the pop-up window and then restart Internet Explorer.  It is only after this point, all Java applets, including those used by Kronos Workforce Central 6.3.10, work.

  What I need to know, is how I can automate the reset procedure from the box "Activate Java content in the browser" after installation, or I'm something wrong or missing a step in automatic installation that is originally for this?

  We use Microsoft SCCM 2007 R3 to perform this upgrade, and everything is run on the client computer by using the SYSTEM account.  First of all, the "javaclean.ps1" PowerShell script is run, with part of the process of command line change of the strategy of running script PowerShell for Bypass.  This script handles the closure of Java-dependent applications and Java deals and uninstall older versions of Java.

  javaclean.ps1:

  #Find all Java products, excluding the automatic update that actually is uninstalled when the main installation is removed.

  write-host "If you are looking for all versions of Java installed" - ForegroundColor yellow

  [table] $javas = Get-WmiObject-query "select * from win32_Product where (name as" Java % ' or name like '% of Java (TM)' or "J2SE %") and <>the name «Java Auto Updater»»

  If ($javas.count - gt 0)

  {

  write-host "Java is already installed" - ForegroundColor yellow

  #Get all Java processes and kill them. If java is running and processes are not killed then this script will call a restart suddenly.

  [table] $processes = Get-Process-name "Java * ' #-erroraction silentlycontinue

  $processes += get-Process - name "iexplore" #-erroraction silentlycontinue

  $processes += get-Process - name "firefox" #-erroraction silentlycontinue

  $processes += get-Process - name 'chrome' #-erroraction silentlycontinue

  $processes += get-Process - name "jqs" #-erroraction silentlycontinue

  $processes += get-Process - Name "jusched" #-erroraction silentlycontinue

  $processes += get-Process - Name 'jp2launcher' #-erroraction silentlycontinue

  If ($processes. Count - gt 0)

  {

  foreach ($myprocess to $processes)

  {

  $myprocess.kill)

  }

  }

  #Loop through the Java products installed.

  {foreach ($java to $javas)

  write-host "Uninstall" $java.name - ForegroundColor yellow.

  $java. Uninstall()

  }

  }

  Once this script is complete, SCCM calls a script VBS "install.vbs" to perform the installation of Java JRE 7 day 51.

  Help on this issue would be much appreciated!

  It turns out that it is actually a problem with Kronos Workforce Central.  We had the parameter 'site.java.plugin.CLSID.familyVersion' as an application set to "clsid:CAFEEFAC-0016-0000-FFFF-ABCDEFFEDCBA", which is the CLSID Java Java 6.  After update this value to "clsid:8AD9C840 - 044F-11 D 1-B3E9-00805F499D93" (the universal CLSID of Java), this problem does not occur when the automatic upgrade of Java.

  We also have good Java 6 and 7 in our environment and did during our implementation of Kronos, so I don't know why we used the Java 6 CLSID in the first place.

• Window Java Applet that automatically close...

  Hi guys,.
  
  I'm using oracle Forms 10 g and internet explorer 6.
  
  My problem is " i have a button in a canvas using the form I want to display a sysdate button so that the button disable ". So I write the code to display the button sysdate when the outbreak of the new instance of the formbelow. the button name is B1
  

  SET_ITEM_PROPERTY('B1',LABEL,'Current Date : '||to_char(sysdate,'dd-mm-yyyy'));

  then I put the function activate No. for this button (property palette) to disable.
  
  After that, I try to run the form, internet Explorer works, but the java applet window is being automatically closed, then I change the feature turned on, Yes , this time java applet windows runs.
  
  How to disable the button without java applet window closes not...?
  
  Thanks in advance

  Hello

  The module forms must, at least, on the point that can have the focus, otherwise it closes.

• Using the java applet on Windows

  I view assessment and I can't figure out how to get the Java applet to run when you use a Windows based PC.  My main thing is that when a user is on the road and they need access to their work stations do not have to install the Client from the view on a random machine.  I can't seemt to understand.  A little help would be very convenient.  Thank you

  Hello

  the Java components are used when you connect from a Linux or Mac device. When you use a PC running Windows with the view Potral, an ActiveX component will push the client to view endpoint and the user there is need of administrator rights to install it.

  What you could do is, ThinApp Client View and give your users on a USB key.

• Strategy + Java Applet file permission

  Hello world
  
  I developed a small Java applet for testing purposes.
  The purpose of the applet is getting data from a MySql database and displays it in a JLabel.
  I use a MySql jdbc layer contained in a Jar file.
  
  I tested the applet locally via Eclipse and it works fine.
  Then I packed my ".class" files into a Jar file.
  I downloaded the Jar file on the server as well as the jdbc Jar file.
  
  I tried to launch the applet located on the server of my browser (IE9).
  An error has occurred.
  I analyzed the results in the Java console.
  As a result, the reason for the problem:
  I miss a grant of permission in my policy file.
  The missing line is: permission java.util.PropertyPermission "file.encoding", "read";
  
  For more information, the policy file is located at: jre7. lib | Security
  
  I do not want to ask users to my future applet to change their policy file.
  So, I wonder if there is a way to examine a policy file custom during the execution of a Java applet.
  The custom policy file would occur on the same server as the applet is.
  
  Thanks in advance for your help.

  But, at the same time, I encountered another problem.
  My applet does not all packages of the MySQL server.
  I wonder if my two self-signed applets cannot communicate with a remote machine because it is not the machine where the jars.
  I know that the applets of sand in box may not.

  It is also possible that there is no path network around where the applet runs on the MySQL server. (Which in general would be a good thing, because exposing a database server to the Internet can lead to problems of security of the data.)

• Pages displaying incorrectly

  When I modified a page today, he then display correctly in browsers of the tests, when he had been showing properly a few days ago. It is a model and a CSS based page, as most of the pages on my site. I couldn't find anything in my code which should make this happen, then I've sailed on all the other pages that I had not changed. They were also correctly displayed in browsers tests. In other words, with the exception of a group of pages based on the same model, but to live in their own folder. I haven't worked on any of these pages except the original who started all this, nor have I changed the template or CSS styles page. Styles appear almost correctly, except that the columns are out of their container. Then, I renamed the page I was working on and downloaded on my server. It shows up there. Any ideas as to what makes these pages displayed incorrectly in browsers tests all of a sudden? BTW, I test it under Firefox and IE7.

  Thanks, Hautecats... I appreciate your response! I followed your advice and replaced my local copy of my stylesheet with my remote copy and enough course. Problem solved. Thank you, once again!
