Creating A New Random Generator Each Time Should Reduce The Number Of Random Repetitions?
May 26, 2011I'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]......

Number Guessing Game - Allows A User 10 Attempts To Guess A Random Number Between 1 And 50
Nov 9, 2009I am attempting to create a game in Visual Studio 2008 that allows a user 10 attempts to guess a random number between 1 and 50. I have a label box in which I would like to display the remaining guesses as they decrement. The code so far appears below.
My two (I am sure very basic) questions are:
1. How would I pass the random integer generated through the Generate Integer function to the AmIRight button's click function? I was trying to decrement the counter each time the "Am I Right " button is pressed.
2. I would also like to evaluate each "guess" when the "Am I right button is pressed. Is it possible to nest a Select Case statement in a For Next Loop?

Create A Random Number Generator That Iterates Through A Series Of Number Between An Upper And Lower Bound?
Jun 24, 2010i wanted to create a random number generator that iterates through a series of number between an upper and lower bound. say between 1 and 100. Basically I want the number generator to pick the numbers randomly and then display them until all 100 numbers are picked without any duplicates. so thats easy I can code that. But what I don't know is how to show those numbers in the order they are generated on a windows form. So i have basically a variable that I will let be changed 100 times (or however many times I want, I don't want their to be a size constraint just using 100 as an example) and each time the number is generated I want it displayed on screen (in a list or something not sure what. Hopefully some type of scrollable list) and each successive number also to be displayed in same format beneath it so that I can see the list in its entirety. What type of form control do i use for that? I could do messagebox.show for each iteration but then user is required to hit ok after each iteration and that would obviously be a bad idea if user selected a large number to work through. Anyways, code isn't exactly necessary just point me in the right direction, i.e.what control (if any) to use.how to format the change in data?

Nov 4, 2008I am trying to create a lotto simulation, but don't know how to continue.I am using numericupdowns to allow users to select 6 lotto numbers. and labels to display what they have chosen, but i'm not sure how to prevent duplicates without creating a large number of If statementsMy question is, is there an easier way to prevent duplicates without writing a bunch of if statements?here is my code:
Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim Lotto1, Lotto2, Lotto3, Lotto4, Lotto5, Lotto6 As Single Lotto1 = Val(NumericUpDown1.Text) lblLotto1.Text = Lotto1 Lotto2 = Val(NumericUpDown2.Text) lblLotto2.Text = Lotto2 Lotto3 = Val(NumericUpDown3.Text)
[code]....
I don't understand how to save the user selected numbers, let the computer generate 6 random numbers, and match the two sets of numbers together to see how many matches there are. As far as I understand the numbers should be stored in 2 separate arrays and then matched together to find any matches.
Random Number Generator Generating Same Number Many Times?
Sep 17, 2011I have this program generating a firstname and lastname from a file. When I run this program I enter information in three textboxes. The first two are the salary low and high(salary1.text, salary2.text) and the last one is the number of "copies"(copies.text) that I want.. When I put a number such as 10 in the text box it outputs some of the same names. The firstname file has around 100 records and the lastname file has about 1000 records Why is it generating the same name The problem is even worse if I do something like 1000 copies.. it outputs the same thing 8 times and then does something different another 8 times
Public Class Form1
Dim sex As String
Function randomfirstname()
Dim infile As IO.StreamReader

View 6 RepliesRandom Selection Of Categories Without Replacement In Visual Basic
Sep 5, 2011Here's the program. there are five categories say a, b, c, d, e, each in a textbox (color blue). There will be a command button say "choose". If i click the choose button, it will randomly choose one category and that corresponding textbox example "a" will change color(color yellow). Then if I want to click the choose button again, the selected category "a" from the first selection will change to gray, then a new category will be randomly chosen without "a" in the list and again will change to color yellow. and so on. So I can click the choose button five times, exhausting the five categories without repeating the category that was already selected.

Generating Salt - LENGTH Of Salt Be Random - Fixed Or A Random Number Within A (min/max) Range ?
Nov 26, 2011VS2010 (SP1) / .NET 4 on Windows XP. The question is simple, the answer; not so much.

Random Number Generating Same Number Every Time?
Jun 7, 2006I heard that you have to add some code to a random number generator
results(1) = Int((5 - 1 + 1) * Rnd() + 1)
so that if it is used again and again it keeps generating new numbers as apposed to what this piece of code does by itself which is creates the same number every time.what is the code?
DataGridView: Getting CurrentRow Number After Row Selection?
Jul 9, 2007I have an inconsistency in behaviour when I try to get the CurrentRow after a row has been selected.
If I select the first row in a DataGridView object using the mouse, the DataGridView1.SelectionChanged event fires, and DataGridView1.CurrentRow is the newly selected row (Row 0).
If I select the first row via code however ie. DataGridView1.CurrentCell = DataGridView.Rows(0).Cells(0) then the DataGridView1.SelectionChanged also fires, but CurrentRow is the old row, not the new row.
In fact CurrentRow doesn't get updated until AFTER the SelectionChanged event has fired if you force the row change in the code, but is updated BEFORE SelectionChanged if you do the row change via the mouse or keyboard.
how to check if its the first row if I've moved to the first row using CurrentCell ?

Jul 13, 2009I was wanting to add a random number generator to an app of mine and I have the code that creates it:
Private Function RandomNumber(ByVal min As Integer, ByVal max As Integer) As Integer
Dim random As New Random()
Return random.Next(min, max)
End Function 'RandomNumber

The way I have it setup is when it generates it I have a MessageBox show it but it pulls the same number a few times in a row. How do I make it pull a different number each time until all numbers a pulled. I then want to add them to a listbox as each one is generated.
