VS 2008 Make Sure Random Numbers Do Not Repeat?
Oct 14, 2009I have done this code but what is a smart way to get rid of repeats?
card1 = random.Next(0, 52)
card2 = random.Next(0, 52)
card3 = random.Next(0, 52)

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.

View 6 RepliesI have to (for class) make a program that generates a safe passwords for people to use. My teacher wants us to make the passwords vary in length, include numbers, letters and upper case letters. I've been able to write code that prints out a random string but it includes unrecognized characters for most passwords. How would I write the code to create a random string that has parameters? (in this case upper case lower case letters and numbers).

I have this code in a function and everytime I call it it return a random number. The problem is I only want the number to be return/generate once. There be times I call the function and it returns the same number as in the pass. Is there a way to random the number once? I know in C++ you use like "Seed" or something and it will only generate once.
Im creating a program that randoms 5 questions and when a certain question is shown then it must not be shown again when the button is clicked. Lets say when "What is my name?"array is shown when the button is clicked then it must not be shown again until the last question that is not shown will be shown.

I'm trying to make an application where when the user clicks a button, it generates a series of 100 random numbers between 1 and 1000, and then saves those numbers in a text file. All I could come up with is generating ONE random number, but I can't figure out how to make it 100. Here is what I have:

I am trying to do a turn-based battle. I want enemyhit to be a random number between enemyminhit and enemymaxhit, and I want playerhit to be a random number between playerminhit and playermaxhit.

I have a program I'm working on (a chance game) that has 5 random numbers generated. I need to think of an expression to check to see if three of those numbers are equal. The random values are not an array, they are 5 separate variables. I have the code written to compare if there are two matching ones, but am having trouble thinking past that. [Code]

View 13 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 RepliesI'm trying to make a program that'll play the card game "War". I've started to code the dealing process, but it doesn't seem to be working. I currently have 3 comboboxes on the form each with numbers representing different cards, 1 that contains all the cards to be dealt, 1 that contains the user's cards, and 1 that contains the computer's cards. I plan to just draw random numbers from these comboboxes for the dealing. However, nothing happens when I click the tool-strip button that's supposed to deal the cards. [Code]

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 trying to make a "guess the musical interval" game, which will play two separate random audio files in succession.So far, I've got it doing that quite well. Here's my issue:I have a list of check-boxes listing off the different intervals that I want potentially hear when I click btnPlay. i.e., if every musical interval's checkbox is checked, I want it to potentially play any interval (unison - octave). Easy.However, if I uncheck "unison" I want my random number x to be not equal to my random number y (x <> y)If I uncheck minor 2nd, I want random number x and random number y to never be 1 number apart (x - y <> 1)?

I'm trying to make a mastermind game program with visual basic. I started of creating the combination maker for the start of the game. Hoever, in my version i don't want any colors to repeat. I used the random function independently to get numbers from 1 to 6. Each number has a corresponding color. The problem, the values still repeat sometimes.
Here's my code for that part:
Randomize
a = Fix(Rnd * 6) + 1
txtA = a

How do I make a loop from 1 to 100 and make it everytime it loops display incrementing numbers to the screen?
View 1 RepliesI 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?)
Here is the code that I have that plays a certain sound
Dim Alarm As System.Media.SoundPlayer = New System.Media.SoundPlayer(Steven_Anderson_HW5.My.Resources.Alarm)
Alarm.Play()
Well, is there a way to make the sound repeat itself after it is done playing?
