I have a problem regarding the generation of random numbers in vb.net..I have code like this!!it generates the random number but both the numbers are same for my program the should not be same!![code]
View 3 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 am trying to teach myself vb (im only 14), and i'm not having a easy time. What im trying to do, i need a user to define a upper and lower bound of a range. From there i need to generate random numbers, a certan number of times, with in that range...this is my first problem.And then, i need to make counters to store/test all of these variables as even, odd, positive, negative and zero's ...that i need to append to a richtextbox to show how many of each. Im not even sure if rtb is the right object to use...you know, instead of textbox, or label?the last thing was to do with Private function as boolean. do I need this to test these variable?

I want to create an array V0(9) using random number generation. For example I generated V0(9) = {1,2,3,4,5,6,7,8,9,1} I want to use 12345 + 67891. How can I separate to use two parts of the array.
My

I'm working on a project that produces quite a few pdf's through Crystal Reports. The problem I'm facing is quite random. Users are reporting that reports sometimes get generated too small (report scaled down to 70% or so and printed upon the pdf) and also that some reports are being printed in landscape while they were designed in portrait and vice versa.
what could cause these random changes in generation? and maybe a solution?
I need to make a form like this [URL] [URL]
For Firstname and Lastname: When you click to random Button it will auto pick random Firstname from Firstname.txt and random Lastname from Lastname.txt
For Username: when you click to random Username Button it will auto generate Username from firstname, lastname, string, number like this
Username = firstname+number+lastname+string
For Password:
Password = random string + random number
The 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 3 RepliesI am writing an application that needs several random numbers. Each time I use the Rnd() function, do I need to precede it with the Randomize() initializer?Or can I just use Randomize() once at the beginning of the code?Examples: Do I need to do it this way?

This code is in VB6.0I have 28 numbers in sequence (eg 1-28), they are randomly generated and displayed in a label. I dont want a duplicate number displayed in the label. Pls how do I do this. Below is how I generate numbers at random. Now I want to make sure there is no duplicate number displayed in the label.[code]
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?

View 10 RepliesI'm working on a Bingo game that generates a random letter and number.
Dim RandN As New Random()
Dim randnumber = RandN.Next(1, 30)
Dim RandL As New Random()
Dim randletter = RandL.Next(1, 5)
All that works, but I'd like it not to repeat a combination. Any tips on how to do that?
Also the random numbers tend to be repetitive and the random letter is never 5. I think the random number has been 30 before but I can't be sure. Is there a way to fix that or just a better way to do the random numbers?

I have a random number generator, an upper bound and a lower bound. I need to use the random number generator to get that many numbers between the upper and lower and then calculate the perecentages of how many are odd, even, etc.

View 2 RepliesI have created a main form.. added 7 forms to the porject.. I want to select the forms at random plus count the forms as they are slected and when the count = 7.. a messgabebox should be displayed.. the forms seem to be selected at random each time i click the next buttoon as i have called the frmmain.random() method from the main form for each click butotn on each form.. but the count doesnt work and all 7 forms dont open.. sometimes 1 form opens then goes back to main screen or it goes past 7. but never shows the message. not sure how to go about it.
