Random Letter & Number Generator

Hello:
I'm new to programming (FormCalc & JavaScript) and I'm using Adobe LiveCycle Designer ES 8.2 to create a dynamic form to post online.  I need help with creating a "random letter & number generator" in code.  The purpose is when someone opens the form online; I will create a unique number/letter combo on the form.
Any help or direction would be much appreciated.  Thanks!

Hi,

  • Why does Firefox change the filenames of pdfs when it opens them? They go from normal names to 8-digit random letter/number sequences

    When I click to open a PDF from Firefox it behaves very strangely. Instead of opening the PDF with its original filename (say for example: Report_on_the_weather.pdf) it changes the file name on opening. They open up with random 8-digit filenames (for example 5918Bd01.pdf). It does this for all PDF files. I would like to stop this behabviour. Any ideas?
    My configuration:
    Firefox 4
    Windows XP
    Adobe Acrobat 8.1 Standard (not the Reader, the full standard application)

    cor-el, thanks for responding. As it turns out the machine was compromised, probably due to the Java upgade from 6.x to the supposedly current 7.x version. I suspect one of the 'always open' tabs in my profile was aimed at a site that had been compromised to exploit the java vulnerability that has not apparently been fixed yet.
    After removing Java, a current Panda AV scan detected three bad jar files. Further testing with MSCONFIG found a file in startup that did not belong, turns out to be a new exploit with very little coverage on virustotal (neither Panda nor McAfee detected it as malware) but as soon as it was taken out of the startup, Firefox started working perfectly.
    Firefox was the parakeet in the cave, tipping over to let me know something was wrong.
    The machine is in quarantine until a much more complete analysis is done. We may still rebuild it to be certain.
    I'm giving you a 'solved' on this because the windows safe mode boot pointed the way to determining the problem.

  • Random number generating too big?

    Hello
    This applet is basically a number guessing game. It uses a random gen for a number the user is supposed to guess.
    I'm wondering if my number generator is causing too large a number for what I need. Because it always says my number I input is too small. I want a number between 1 and 1000.
    thank you!
    import java.applet.*;
    import java.awt.*;
    import javax.swing.*;     // JApplet , JLabel, JTextField, JButton
    import java.awt.event.*;
    public class GuessAgain extends JApplet implements ActionListener{
    int theNum;
    int yourGuess;
    int retNum;
    // declare refs to GUI components
    JLabel YourguessLabel, numIsLabel;
    JTextField YourguessField, numIsField;
    JButton againButton;
    // setup GUI components
    public void init(){  
    // obtain content pane give control to layout manager
    Container container = getContentPane();
    // new object of class FlowLayout
    container.setLayout( new FlowLayout() );
    // "Your guess" label
    YourguessLabel = new JLabel( "Guess a number between 1 and 1000:" );
    container.add( YourguessLabel );
    // field
    YourguessField = new JTextField( 10 );
    YourguessField.setEditable( true );
    container.add( YourguessField );
    YourguessField.addActionListener( this ); // register this applet as YourguessField's actionlistener
    // "Try again" button
    againButton = new JButton( "If wrong try again" );
    againButton.addActionListener( this );
    container.add( againButton );
    // "Number is" label
    numIsLabel = new JLabel( "Number is:" );
    // field
    container.add( numIsLabel );
    numIsField = new JTextField( 10 );
    numIsField.setEditable( true );
    container.add( numIsField );
    numIsField.addActionListener( this );
    retNum = makeNum();     
    }// end init
    public void actionPerformed( ActionEvent event ){
         int yourGuess;
         yourGuess = Integer.parseInt( YourguessField.getText() );
         theNum = makeNum();
         displayMessage();
    }//end actionperformed
    public int makeNum()
         int theNum = 1 + ( int ) ( Math.random() * 1000 ); // number generator
         return theNum;
    }// end makeNum
    public void displayMessage()
         if( yourGuess == theNum )
              showStatus( "You got it!!" );
    else{
              if( yourGuess > theNum )
              showStatus( "You are too high." );
              else
         showStatus( "You are too low." );
    }// end else
    }// end method display message
    }// end class

    A troubleshooting technique is putting System.out.println statements to validate the programmer's opinion on how the code is supposed to work. If you add a System.out.println(yourGuess+" "+theNum); line as the first line in the displayMessage() method, it would validate your hypothesis that theNum is too large.
    A hint to the problem - when you declare a variable inside a method with the same name as an instance variable, the compiler uses the method variable, not the instance variable.

  • Plot xy graph using random number generator

    How do i plot xy graph dynamically every 5 seconds with a random number generator?
    X axis : Time
    Y Axis : Random number generator

    I've done tis so far. im able to plot dynamically every 1 second.
    but the problem i am facing is The X axis display every 1 second.
    i want it to be fixed 24 hours time format, and the data will gradually plots the data on y axis against x axis every one second, without changing the scale of the x axis (24hour time format)

  • Java random number generator

    Hi does java have a random number generator. If it does can you point me to it please. Thank you.

    you can use "java.Math.random()" this function returns a value which is greater than or equal
    to 0.0 and less than 1.It returns a double value,so you can multiply by 10 and cast it to int,so that it
    can produce numbers between 0 & 9.Yes, you can do that. But, as stated before, java.util.Random has methods that are easier to use for random int values than using java.Math.random is for random int values. It all depends what the OP wants. The OP hasn't come back with additional questions, or to say that he found his answer. So, we don't know whether he has his answer (he has several options now!) or not. :)

  • Random Number Generator setSeed(); method???

    I've searched and can't get a good understanding of the setSeed() method. I am suppose to use the loop control variable to seed the random number generator inside the loop. I need to use the same input everytime I use the random generator. When I compile it says int cannot be dereferenced.
    for(int i = 0; i < array.length; i++)
    int randnum = generator.nextInt(100);
    randnum.setSeed(i);
    array[i] = randnum;
    If anyone can explain the setSeed() method that would be greatly appreciated. Thanks!

  • Random number generator. Even and odd numbers

    I have a problem.
    I have a random number generator, it goes from 0 to 20, I need to have two indicators, one will show how many numbers are pairs, and how many are not.
    I tried to use the decimated 1D array, but since those numbers are random, it doesn´t work for me. I´m new with LabView, and I don´t know if there is some other way to make it work, I need some help, especially with some examples.
    Thank you so much.
    Solved!

    Create the array.  Use quotient remainder to divide by 2.  Now you have an array where all the odd numbers are now 1, and all the even numbers are now 0.  Sum the array and you have the total number of odd numbers.  The number of evens will be the length of the array divided by the # of odds.

    Haha I lost sight of the fact that he was looking for the amount off odds and evens.  Good one.

  • Help: JSP Random Number Generator

    hello every one,
    Im trying to generate a random number using currentTimeMillis(), in Jsp, can you help me out and advice me how can this be done please.

    First you say you want a random number, then you say you want a unique one. Which is it?
    Random numbers do not normally guaruntee uniqueness.
    is there away i could use the currentTimeMillis(), What would you use it for? System.currentTimeMillis() is commonly used as a seed for a random number generator. The java.util.Random class uses it like that - take a look at that API link.
    Or if its a homework question state the exact requirement - I'm guessing here.

  • Random NUMBER generator help..

    Hi all,
    i'm having issues with my random number generator i'm trying to fill my array with random numbers but i keep getting it filled with zeros.... can any one tell me what i'm doing wrong i can;t figure it out..
    for (int i =0; i < 100; i++){
                        int x=(int) (Math.random());
                        data[i] = x;
    }

    From the API "Returns a double value with a positive sign, greater than or equal to 0.0 and less than 1.0."
    So casting the value to int is always going to result in a zero value.
    You need to multiply by a value that is one larger than the value you want to be your maximum. For example:
    int x = (int)(Math.random() * 100);
    should create a random number from 0 to 99

  • Defining a lower boundery for a random number Generator

    Hi,
    I am using the code:
    Random rand = new Random();
    int x = rand.nextInt(50);
    to generate a random number between 0 and 49
    However I now need to only select a number between 20 and 49
    Is there any way to give the random number generator a lower boundery as well as an upper boundery ??
    Thank you
    Craig

    example:int x = rand.nextInt(30) + 20;Will generate a number between 20 and 49.

  • How do I create a random number generator?

    I know I've done it before...but I can't remember quite how to get it going. I'm creating a math tutor program, which generates two random numbers and asks the user to add them, and if the answer is right they get a message that gives props and if they get it wrong they're told they got it wrong.
    I can't get too far because I've forgotten how to make the number generator, so what exactly do you put in to get it?
    import java.util.*;
    public class AssignmentFour3 {
         private static Random integer = new Random();
         double number1 = 0;
         Random string1 = new Random();
         }

  • Does Labview have a Random Number Generator for U16 with a periodicity greater than 64 Million instances of U16words and one with SEED as the connector?

    We are doing some testing that requires 64MegaWords be written to our DSP memory  with random values to do a validity check and without repeating sequences with using the previous value as the seed for the next and us passing it the initial seed.  The dice one doesn't meet that criteria, and I was not sure how the continuous random number generator parameters work and if any of them would meet this criteria. Anyone have any information that might help?
    Thanks,
    Sue

    Hi suem,
    There is no reason why you couldn't simply write a pseudo-random number generator by yourself. Simply select a random number algorithm you want to use and implement it in LabVIEW. You do not need to interface code written in another language in order to implement a pseudorandom number generator. If you have a DAQ card or something, you can also use inputr noise or some other hardware soruce to generate real random numbers. For that also LabVIEW is an excellent tool.

  • Uniform random number generator

    anyone of u know how to generate UNIFORM RANDOM NUMBER GENERATOR that has serious faults ?

    uj_ is right (never thought I'd say that).
    ANYTHING "uniform" is by definition not random.Well, the correct term is "random numbers from a uniform distribution". And there certainly exist such generators (athough they're pseudo-random of course).
    I lost my temper because I've spent considerable time helping sosys only to realize he's a notorious cheater. Sosys claims to be a college student attending a CS class. With the knowledge, or rather lack thereof, he's displaying he must've cheated systematically for a long long time. I'm quite liberate at helping people with their homework but I won't help a leech become a programmer.
