Generate A Random Number Sequence That Is Non-repeating In .net ?

Apr 4, 2011

I am writing a matching program, and need 24 objects to randomly appear, each twice, across 48 spaces. I figured the best way for me to do this would be to assign the positions a number 1 through 48. but the problem is I can't find a way to generate a random number sequence in visual basic 9 .netI found many examples in visual basic .net but the conversion doesn't work. If not some code, many some example programs that either use a random number sequence or randomly sets the position of objects.

Ok im making a program that throws three dice at once. Several results end with a score but a few result in a no score. in the case of a no score (Example: the dice land on 4,1,6) i want the dice to be thrown again. If there's 3 no scores in a row then it counts as a loss.I have no clue how to get it to repeat after a no score or to limit i

How To Generate Unique Random Number

Aug 2, 2009

I have an application that is made for a game that you have to draw cards for. So what I have done is created a random number generator that generates a random number and then using case statements that number is associated with a picture of the card, which is displayed in a picture box. This part works fine. Each time I draw a card it is not reshuffled so I need to store the random number generated and then if that number is generated again ignore it an generate a new number.

Now to complicate matters even further when a certain card is drawn the entire deck is reshuffled and everything starts over again. Here is what I tried... I tried using arrays to store the numbers but I cannot seem to get it to search the array for the number or store the number properly within the array. The array has to be dynamic since the game is expandable and I will be adding more cards to the game in the future.

Random Number Generate (within Range)?

Nov 30, 2009

The object of this project is to write a computer program that will allow the computer to guess a number that you have selected. The computer will make a guess and you, the player, will tell the computer if it guessed too high, too low, or that it guessed the number.The program will also allow the player to start a new game or to exit the program. PROJECT INSTRUCTIONS:

1. Create a form with a labeled box to display the computers guess.

2. Create a new game and an exit button.

3. Create objects to indicate if the guess was too high, too low, or right on target.

4. Create program code to respond to the player�s indication by selecting and displaying a new computer guess.

5. When the computer guesses the player�s number, reset the so that a new game may begin.

I have done all as above and so far my code looks like so

Public Class Form1
Dim Guess As New Random()
Dim HGuess As Integer, LGuess As Integer, current As Integer


The problem i ran into is that if for example a user has a number 24, when the program makes an initial guess of 50,i want to be able to click low, and the program should generate a lower number say example 22. If i then click higher as my actual number uis 24, the program should not shoot higher than a number it has previously guess incorrect (in this case 50) it should guess anywhere from 22 - 49 and in turn limit the range of the next consecutive guesses it till hits the right number. My code right is guessing as it shuold but not within the limited ranges.

.net - Shortening A Repeating Sequence In A String?

Jun 30, 2010

I have built a blog platform in VB.NET where the audience are very young, and for some reason like to express their commitment by repeating sequences of characters in their comments.


..and so on.

I don't want to filter this out completely, however, I would like to shorten it down to a maximum of 5 repeating characters or sequences in a row.I have no problem writing a function to handle a single repeating character. But what is the most effective way to filter out a repeating sequence as well?This is what I used earlier for the single repeating characters

Private Shared Function RemoveSequence(ByVal str As String) As String
Dim sb As New System.Text.StringBuilder
sb.Capacity = str.Length

Receive A Number Of Random Numbers To Generate?

Feb 26, 2012

I'm so confused. Please help me with this program. My teacher wants Receive a lower bound and an upper bound of a range.Also receive a number of random numbers to generate.Generate this many numbers in the specified range and keep track of how many are even, odd, negative, 0, and positive. Do not save the numbers, just the category counts.

Lower bound must be less than or equal to the upper bound (negative or positive or mix).Number to generate must be greater than or equal to 1.Use the GetInput Boolean function (written in class) to retrieve the numbers for data validation, however it must be changed from Double to Integer. Then use additional functionality to test whether they are in the specified ranges. For example, if you successfully GetInput for LB and GetInput for UB, then test LB <= UB. If successful, continue with GetInput for Number to Generate and check >= 1.

How To Generate A Random Block Of Number Of Cells In Two Dimensional Space

Nov 25, 2009

I am using VS2008. I worked on this problem for a time, but I was not successful doing it. Below is the VS file.I need to produce a grid of cells and have some random features as shown below which is an example of a world of (500 x 500) units (or any other size and grid size). It contains three areas (of 11 cells, Value of each cell = 108), two green areas (of 8 cells, Value of each cell = 137) and one river. The start point of the river should start from one of the world edges and finish to another one. Please note that number of feature could increase or decrease according to user inputs.The question is, how can I produce these features randomly? To clarify the question, I will read the number of areas from a form. I need these features so that the number of cells should be distributed randomly beside (attached to) each other in the world. The rivers occupy one sequential grid line. My problem is how can I randomly generate the features according to number of cells??

Hangman Game - Generate Random Number When User Press Start Button

Jul 29, 2009

i've created a hangman game (Fully working) but since you can only "play" with one phrase (10 letters) it gets boring fast. Basic the current game works by on form load i define the slots (10 string which each hold a letter) and give them there letter. then the user type in a text box and if the textbox = any of the slots then the lbl repasenting that slots changes its text from "_" to the letter.

Anyway what I would like the button to do is when the user presses the start button a random number is generated. The program then looks into a textfile and based on which number is generated it takes a certain line (10 characters per line in a phrase) , moves them into the slots and the game starts. Is that possible to code or it too complicated. The textfile will be in the applications folder (words.txt).

Non-Repeating Random Numbers?

May 23, 2010

I'm working on a Bingo game that generates a random letter and number.

Dim RandN As New Random()
Dim randnumber = RandN.Next(1, 30)
Dim RandL As New Random()
Dim randletter = RandL.Next(1, 5)

All that works, but I'd like it not to repeat a combination. Any tips on how to do that?

Also the random numbers tend to be repetitive and the random letter is never 5. I think the random number has been 30 before but I can't be sure. Is there a way to fix that or just a better way to do the random numbers?

VS 2010 - Random Sequence Generator For Names

Mar 1, 2012

For a school project I need to create an application one element of that it puts 14 names into a random order, I figured the best way to do this was with an array and a for/next loop (it cannot repeat the names) each name would be declared as a string with the name of the variable being a number between 1,14. Then there would be a text box relating to each index of the array, I am sure you get what I mean. However, my for/next loop seems to be getting stuck and causing the application to halt and I cannot seem to work out why.

Here is my code.
Public Class Form1
Dim iNumber As Integer
Dim arrNumber(0 To 13) As Integer
Public Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
[Code] .....
I have yet to write in the section which converts the random numbers into the names, as I discovered this error whilst debugging the for/next loop.

Creating A New Random Generator Each Time Should Reduce The Number Of Random Repetitions?

May 26, 2011

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 ifI 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]......
