I want to repeat a random number sequence generated by a legacy software using the VBMath.Rnd and VBMath.Randomize functions in VB .NET Reading on the documentation for those functions on MSDN i found that you are supposed to "reset" the generator calling Rnd with a negative value if you want the same seed to give you the same result sequence each time. But doing some tests... things didn't work as expected.

c# - Obscure VBMath random numbers generator behavior
View 2 RepliesI am trying to write a random number function that can just be called from my main module to generate different random numbers. I have tried this several different ways and I am having odd results. Approximately 19 times out of 20 the numbers come back exactly the same, but approximately 1 in 20 they come back as two different numbers. Im using Visual Basic Studio 2008. Here is the code I have so far, or rather, the current version of my many tests I have been running to try and figure it out. Sometimes it takes many runs of the program before the two seperate numbers apear.I've been researching it and have come up with nothing so far.I know I could put them in the module section as two different randoms and it works, but I get extra points if i use a couple classes in my program.This is the main module.
Module Module1
Sub Main()
Dim randomNumOne As New RandNum[code]...........
Right so my generator is working, but I now want to take the numbers that it generates and add them to a list of generated numbers. So you can monitor what numbers have been generated. then ideally a way to exclude these numbers from being generated again.

I've read numerous posts and threads about random number generation, but I havent' run across this.If I generate a bunch of random numbers, the results are radically different if I create a new Random generator for each number than if I use on Random generator for all the numbers. The results are much more consistent and evenly distributed if I use the same Random generator.I would have thought the opposite,because creating a new Random generator each time should reduce the number of random repetitions, if a different time slice is used to create the random number.[code]......
View 9 RepliesI was wanting to add a random number generator to an app of mine and I have the code that creates it:
Private Function RandomNumber(ByVal min As Integer, ByVal max As Integer) As Integer
Dim random As New Random()
Return random.Next(min, max)
End Function 'RandomNumber
What I can't get to work correctly is the following. I have a textbox for the min and max. The way I have it setup is when it generates it I have a MessageBox show it but it pulls the same number a few times in a row. How do I make it pull a different number each time until all numbers a pulled. I then want to add them to a listbox as each one is generated.
Im doing a project where the computer generate a random date and the user has to guess what day of the week it lands on. I have the random generator but I would like to change it where the month is not a integer.For example, March 30, 2012 instead of 3/30/2012. Here is my code so far [code..]
View 1 RepliesCreate an application that allows the user to guess a random number generated by the computer.When the user makes an incorrect guess, the application should move an image either upr or down, depending on how the guess compares to the random number.If the random number is greater than the user's guess,the application should move the image up to indicate that the user needs to guess a higher number.If the random number is less than the user's guess,the application should move the image down to indicate that the user needs to guess a lower number.The game ends when the user guesses the random number.However, the application should allow the user to stop the game prematurely.When that happens the application should siplay the random number.I have tried every which way I can think of including using a textbox instead of an inputbox and playing around with the syntax - but just can't seem to get it right.[code]
View 1 RepliesI need to create a multi dimensional array comprised of random numbers between 1 and 4. The reason why I need a mutidimensional array is because each number needs to be associated with a random letter of F or N. [ F or N are really Indicators or whether I should show the user Feedback on their results in the case of F. Or not show them Feedback in the case of N.] So within this array 2 random numbers will be associated with random F's. And 2 will be associated with random N's. For example the array should look like (1,F 2,F 3,N 4,N) or (3,N 2,F 1,N 4,F). The reason why I need this random array is because during the course of my application being ran 4 times (which represents the numbers) I want to insure that every time N is done 2 times and F is done 2 times. This is all to make sure that each Number 1-4 after 100 times the application is ran has the same amount of F's and N's. I was also wondering if someone knows a way to store how many times the application has been ran in asp.net so that I can recreate another random string after 4 application runs.

We handle all the user account creations, access rights, file shares, terminations, badges...etc. To make the task of user accounts creation easier, I am looking to create a Password Generator that runs off of "Word Banks" if you will.Right now I have 4 ComboBoxes with a list of words in each. I want to make it so that when I click "Button1" it will Randomly populate each ComboBox with a word from their respective lists and then all compile, in order, in a TextBox at the bottom of the App so we can copy it out to use for our respective account creations.

View 9 RepliesI'm trying to create a random name generator, and in order to store all the names I'm using an SQL database. I've got the database set up (simple version just until I get it working) and here's basically what I want the program to do. My database consists of three main fields: Name, Gender, and Origin (along with corresponding ID's). I want the user to be able to use a drop down combo box to select the gender (m or f) and the origin (i.e. English, German, Chinese, etc.), have the program filter out any data not within these parameters, randomly choose one of the remaining names, and display it on the form in a label. I'm not quite sure how to get the combo boxes linked to the data set so that, when running, the chosen item filters the data.

View 3 RepliesSo I've been wanting to make a random password generator for a while now and I was looking around on here for the code to do so. I came across this:
Dim random As New Random
Dim password As New System.Text.StringBuilder
For i As Int32 = 0 To 9
[Code]...
And I used it successfully. The only thing is I want to change it slightly. I want to change it to where, only a few are letters, and the rest are numbers. But for them to be combined. One example could be "DM23TH91PB". How would I go about changing this to do that?
I want to make a random word generator. Like just the words that I type in the script though. Could anyone please give me the code?
It would just be a simple word that appears in a text box. But in the script it puts one of the random words i tell it to every time you click the button. I know lua 5.1 scripting a little. I'm only 13 though. So as you can imagine I'm no mastermind at code.
button1 function onclick
print word.math;random(word1,word2,word3,etc)
I would like to know if what I have here is correct? could it be done better? is there something I could add or take away? or is it finished and does what it does? I'm also posting it so that other beginners can maybe look at it and learn from it, just copy and paste the code in to a new Windows Forms Application, hit F5 and then Space bar.[code]
View 16 RepliesI am doing a Coin Toss program for school and I'm getting my butt kicked by this thing. The following are the instructions exactly as my instructor gave them:Use the random number generator (see the code below) to simulate a coin toss. First ask the user for the number of repetitions. Next, set up a For loop to execute that many times. Each time you enter the loop, call the random number next method. Assume that a random value <= 5 is considered a "Heads"; a value >5 is a "Tails". That is, if the random value is <= 5, add one to an accumulator named intNumHeads. If the random value is >5 add one to an accumulator named intNumTails. When the loop finished, output the number of heads and the number of tails in a text field with appropriate labels.Dim intRandom As New Random()Dim intNumber As IntegerintNumber = intRandom.Next(0, 9) In my application I have the click event of the "Flip Coin" button coded as follows:

View 17 RepliesStuck programming a random number generator game. one is to guess what the random number. I have coded most of it and am pleased, but there are some hitches. a) When running the program if you guess 10 it says," Guess Higher" which is impossible as the num gen stops at 10 (if you guess 9 and the number is lower than 9 it says guess lower . . . which it is supposed to do)
b) When asked to play again if one clicks no it calls you a loser and exits the problem is it does the same if you click yes. How can I get it to simply start over if yes is clicked
c) Does anyone know how to make an image move up or down based on the input? IE if guess needs to be higher the image moves higher? Lower and it moves lower?

how to generate a list of numbers, from 1 to 10 in a random fashion but with no numbers repeating. For example, every time the code is run, it will return an array of numbers, each different, only using numbers from one to ten?
This may sound confusing, so i will try and explain what I am trying to do with it. I have a form that displays 10 questions and each time a user moves to a new question, i want to display a new picture. the pictures will be named "picture1" through "picture10". I want the order that the pictures are displayed to be different every time.
I want t to equal a new random number everytime but it only gives a random number the first time and then uses that same number everytime.

2. I also need to separate each letter of the word and display an image for each letter, and each letter going to the next based on a timer, and can also repeat on a button click.
Eg: TWO would end up displaying T W O, a few seconds apart from each other.
now need to make it slightly more complex by the use of if statements. The concept itself isn't difficult for me, its the implimentation of it in this case.
