View 2 RepliesI have this code to pick a random number Between X and Y
X = Minimum Number
Y = Maximum Number
But the problem is i wanted to know if there is a better random function than the one i have.
Because right now i put
Min = 1
Max= 2
and it keeps picking 1
if i had min =1 and max =2 i want it to pick 1 sometimes and 2 sometimes
and now i tried min = 1 max = 3 and it never picks 3, it only picks 1 and 2
ok
Public Class Form1
Public Function RandomNumber(ByVal MinNumber As Integer, ByVal MaxNumber As Integer) As Integer

anyone know how sql pick a random number of primary keys, I know get max number and call a random number work but what if there a missing numbers like 1,2,4,6,7 so max 5 and random will missing 6 and 7 also there a error if 3 and 5 come up.
View 1 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.
getting random number from list of numbers is getting me sick. i am trying to do it for like 20 days now but every time i do it ends up in a loop wich crashes the my.settings system. does anyone have an idea how to get a random number from a list. then delete that number so it cannot be called again. my system must mark some items with numbers but non ofthe numbers may be used more then 1 time the max items in my system is 90. so from 1 to 90 without getting 2 times the same number heres the code i tryd

i need a simple way to get a random number from 2 numbers. This means that for example if my 2 numbers are 3 and 7, i don't need a random number between 3 and 7 that would be like 3,4,5,6,7 but only a random that is either 3 or 7. Meaning not all the numbers between x and y, but either x or y.
View 7 RepliesIf I have say 5 numbers: 1, 29, 53, 95, 103 What would be the VB.net code for randomly selecting a number of those 5.
i.e) The random number has to be 1, 29, 53, 95, or 103 and has to be randomly generated.
I've tried using the Int(Rnd() * 104), but I do not know how to make it choose only these 5 numbers!
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.

I 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]...........
I basically have a .avi file that speaks numbers (random number only). Want I want the program to do is:
1. Load up the .avi
2. Play the .avi and write down the numbers that are begin said.
3. Write them in a textbox / notepad
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'm realy green when it comes to programming but I like to think I am learning quickly. However, I cant figure out how to generate a number of random numbers baised on the vailu of a numeric slider. So for example I am generating a number between 1-12 where each point of value for the slider would generate an indiigual number that can all be added to a final total. I would also like to be able to back the slider down to a previous number and have the same total I had last time I was at position x. This is what i have so far:

Im working on writing a program for doing standard deviation and as of right now im running into one slight issue with subtracting my mean from the original numbers. I will post most of my code so you can get an over view but i mostly just want help on this one little part for now. Im going to be making a website for school and put some programming stuff on it so i wanted to make just some random programs for it so this is school related but not really homework. It's line 26 and 27 that this is relating to. When i put a stop in my code and look at the result of arrayDifferences it gives me 0.0 when it should be -1. I know i can go this route and say arrayDifferences(1) = arrayDifferences(1) - arrayAvg but seeing as how i want this to be a random number of numbers input by the user i cant do that.
CODE:
i have four labels, and for item on Arraylist. how do i set the text of the labels from the Array list, at Random
Each label should pick and display one of the colors. one label should display different item each time i run the program[code...]

how I pick a random item from a array?Here's the little bit of code I got:
Dim array() As String
Dim words As String
words = "hello*123*abc*zxw"
array = Split(words, "*")
But what should I do next to randomly select a item from "array"?
So what I'm trying to do is not so much generate a random word but pick one from a collection. I was thinking on generating a random number since that is very easy, then picking a word acording to the number generated. Is there a more efficient way of doing this?

And to make it fair and unbiased i need an application that can choose randomise a word from the list box then transfer the string to the text box. So basically something that can pick a random string from the listbox and show it in the textbox1.text property.

The Textbox.Text will be a new Item in ListBox when Button1.Click I want button2.click to pick a random item from the listbox and display it as the label. Think of it as a random raffle picker lol.
I need to have two pieces of software, made in vb where one encrypts the contents of a .txt file, and the other decrypts it, and then picks one word at random and displays it each time a button is pressed, but never displays the same word. Or, if there was a way to hard code it into the program as there is only 5 words that would be better.
View 1 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 8 RepliesI'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]......
