Random Numbers In Your Array?
Feb 22, 2011How Can I random the numbers in my array but they will not repeat the array value. The array number starts from 11 to 14.
Or how can I random 4 buttons.text that uses array to call their text?

I have not messed with VB much and I have been trying to do something that has me stumped. I wanted to create an array of 10 random numbers. Each of these numbers then is printed onto a label. From here I have two more labels that show the highest and lowest value. I got the first part, 10 random numbers show up but then things get shaky. This is what I have thus far.

Generating random numbers in an array HELP
View 6 RepliesThe first problem I am having is that it populates every cell with the same random number. How do I get it to create a new random number? The second problem is that I need to make sure each entry in the array is unique.

So I know how to an unique random number in a 1D array but In an 2D array looks so difficult or strange for me[code]...
Is their an other solution for an unique random number 2D array?
I am trying to create an array of 5 random unique numbers between 1 and 30. I've been trying for a while and have had no luck.
View 9 RepliesI'm trying to make a Bulls and Cows type game, I was able to do it fairly easily with javaScript, but VB is killing me. I can get the array 5 slots long with random numbers, unfortunately they're all repeats. when I try getting no repeats I run into infinite loops, exponentially increasing array lengths, and just plain old arrays with 5 numbers randomly generated, but with repeats.
I'm trying to do this with loops, in JS I did it using regular expressions
Here's an example of my code.
Public Class Form1
Dim intRand(0) As Integer
Dim RandomClass As New Random

I am writing a program for a class on visual basic and i have a listbox that displays 15 random numbers using an array. Then there are 2 buttons(max and min) that when clicked displays the largest number in the list and the smallest. how do i get these buttons to do this?
View 6 RepliesI want to set an array upperbound limit to 50. I need a loop to create a random number and place it in the array until it reaches 50( I've set up the random generation part). My question is do I set the upperbound limit when I create the array and redim for each sample being added or set the limit somewhere else? I understand how to set up a basic array and how to redim arrays, but adding the loop to it is confusing me.[code]...
View 4 RepliesI'm new to the forums and VB programming in general, so I only have a very basic understanding of VB commands, but I still have a good grasp on logic and the like. I'm doing this for a school assignment, and I am in a bit of a pickle.I am trying to generate an array of 6 random numbers from 1 to 30, making sure there are no duplicates.I think I'm pretty close to cracking it, but it still doesn't work.Here's what I have at the moment:[code]......

View 7 RepliesI'm creating an application that creates a list of 20 ramdomly selected numbers within an array and displaying those numbers in a listbox. I then need to display the duplicate numbers in an adjacent listbox by clicking the find duplicates button. How would I be able to access those 20 numbers in order to find the duplicates?

My project is basically a addition test for 5 to 9 year old children. On my form I have a button which when clicked, it inputs a number from 1 to 10,( which is chosen by the user via an combo box drop down), into ten text boxes. I have built and array and used a, for loop for this and it works fine. [code] My problem is I need to create another array connected to the same button to genarate 10 random numbers. Which will allow the user to add the two numbers together.My problem is that visual basic wont let me add a second array to the same button?
View 6 RepliesThe class Random is out right defective. It always produces the same random numbers in the same sequence. Things I have tried so far is every kind of seed you can think of as well as Randomize. The result is that I always get the same random numbers in exactly the same sequence.
View 4 RepliesSo how would I use .next (random numbers) to randomly select something from a list of numbers but it can't repeat the number?I could do:
dim num as integer
dim r as new random
num = r.next(1,5)
if num = 1 then
elseif num = 2 then
etc.
That wouldn't work because it would repeat.If I donwload someone's game can I disect it in VS? :0 I tried going to open project, then I went to the folder and clicked open. It brought me inside of the folder so I tried to open the game but there is no form1 there. It says the games name then .exe in the explorer-like thing in the top right?Also, how would I have a value or something in a label and access it from a button.
Example:This is in a label.
Dim number as Integer
number = 0
Then in the button do
Label.number = 0
How would I do something like that? I want to use that a lot as I did in a different language.
The program must generate 6 unique random numbers but when I click display numbers sometimes it gives me 6 unique numbers and sometimes I get duplicate numbers. I will add the code I have so far.

I don't take programming lessons at school or anything, and I'm starting to (try to) teach myself about random things.Currently I'm making an app that has 3 functions:
-Random Integer (1 to 100)
-Random Answer (Yes or No, similar to a coin flip)
-Random Dice Roll (1 to 6)
How would I go about doing this?At the moment all I know about random numbers etc. is that I will need to do something along the lines of Dim dice As New Random or something like that, but, like I mentioned, I have no idea.I am well aware of the DIC rules that you won't write the code for me/do my "homework(?)" for me, and that's not what I'm asking.
Basically, I want to divide two numbers together and they should be 2 random numbers from 1-12 (I have done that part) but, the answer should be a whole number (i.e. Integer, so no decimal points etc) So, I did the following:
' Initialize the random-number generator.
Randomize()
' Generate random value between 1 and 12.
Dim value5 As Integer = CInt(Int((12 * Rnd()) + 1))
[code]....
but the problem here is that the program crashes after only a few clicks on the button. So I guess the question is: How can I make the program generate two numbers (from 1-12) that when divided become a whole number?(Is there any code that may tell the random generator that I want the numbers to be even?-so all even numbers from 1-12?)
i want to know how to generate 7 "differents" random numbers.
I need to use a tab() with 7 entries and verify(with a loop?) if the generated number is or not present in the the table, if not then increment a counter by 1 and add the number in the table and increment the table position by 1 for the next randomized number.
Im not sure how to do the verification, so far all i have is a function i made for the random number between min and max:
Private Function randGen(ByVal min As Integer, ByVal max As Integer)
Dim random As New Random()
Dim i As Integer

View 12 Repliesi have a few questions about generating random numbers:1) is it possible for the programme to generate a random number that it has previously generated (i.e could it produce the same number more than once?)2) can you specify what numbers to generate? e.g only whole numbers up to 1000?
