Generate An Array Of 5 Random Numbers (with No Repeats)
Dec 12, 2009I'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

View 6 RepliesSet Array Bounds And Filling With Random Numbers?
Apr 1, 2011I 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]...

Create Another Array Connected To Same Button To Genarate 10 Random Numbers
Jun 5, 2011My 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 4 RepliesUse .next (random Numbers) To Randomly Select Something From A List Of Numbers But It Can't Repeat The Number?
Aug 16, 2009So 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.
How To Generate Unique Random Number
Aug 2, 2009I 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 Numbers And Random Strings
Nov 24, 2009I 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.

View 7 RepliesDivide Two Numbers Together And They Should Be 2 Random Numbers From 1-12?
Jan 10, 2010Basically, 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?)
