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.

Bug In VB 2010 RC - Class Random - Always Produces The Same Random Numbers In The Same Sequence

Apr 4, 2010

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.

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.

How To Create Random Strings With Parameters

Jan 17, 2012

I would like to make a program that generates a safe passwords for people to use. I want 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).

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

Aug 28, 2010

I need to generate a lot of random 2 character strings for my application. it's a VB console application. basically what I have tried for random strings is this:

Private Function GenerateRandomString(ByVal intLenghtOfString As Integer) As String
'Create a new StrinBuilder that would hold the random string.
Dim randomString As New StringBuilder

What is going on? I thought that I used to, a long time ago, be able to just do random.Next.

Creating A New Random Generator Each Time Should Reduce The Number Of Random Repetitions?

May 26, 2011

I'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]......

Generate 10 Random Numbers Between 1 And 52?

May 1, 2012

'm attempting a program and need to generate 10 random numbers between 1 and 52. However all the numbers must be different. I'm trying this in a For Loop. I'm not terribly amazing at this so all I have so far is:

Dim B, I, J, max, min, card() As Interger
max = 52
min = 1
Randomise()

Generating Random Numbers?

Mar 14, 2012

i 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?

Non-Repeating Random Numbers?

May 23, 2010

I'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?
