Create An Array Of 10 Random Numbers?

Apr 19, 2011

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.

Generate An Array Of 5 Random Numbers (with No Repeats)

Dec 12, 2009

I'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

Set Array Bounds And Filling With Random Numbers?

Apr 1, 2011

I 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]...

Function To Create Specific Amount Of Random Numbers

Apr 5, 2009

I am currently taking a introductory level class to vb.net. For the assignment it asks to create two functions. One function should create a random number within a given range. I have completed that part. What I am having trouble with is the second function. It wants the next function to use the previous function three times so that it displays 3 separate random numbers within a given range and display it in a D2 string format.

I also would like to do this with combo boxes and their selected indexes. So if the combo box has 10 items in it; the new selected index would be the random number generated above.

Use .next (random Numbers) To Randomly Select Something From A List Of Numbers But It Can't Repeat The Number?

Aug 16, 2009

So 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.

Random Numbers And Random Strings

Nov 24, 2009

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.

Divide Two Numbers Together And They Should Be 2 Random Numbers From 1-12?

Jan 10, 2010

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?)

Get 7 Different Random Numbers?

Jul 3, 2009

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
