I am trying to figure out a better way to basically predict a random pattern from a previous set of numbers. I figured the best way would be to use a for next loop and try different random seeds until a pattern matched, but it seems that it would take forever Lets say you had 3 random numbers: 2, 5, 12
Code:
Dim RandomGenerator as New Random()
Dim FirstNumber as Integer = 2
Dim SecondNumber as Integer = 5
Dim ThirdNumber as Integer = 12
[code]....
The above code does work to an extent, the problem is it takes so long to process. Is there any way to feed in the random numbers and have .net spit out a seed that matches them?
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]......
I am trying to make a texas hold em game and it is of the utmost importance that my code generate a random number. But using a random number function that I always end up with a lot of the same numbers over and over again. Any ideas on how to make it "TRULY" random? [code]
I've made an image viewer which opens a random image from a specified folder, but the random number is not that random at all... I've already used Randomize(), but without result.
I 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?
vb.net Option Explicit OnOption Strict OnOption Infer Off Public Class frmMain Private Sub btnExit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnExit.Click Me.Close() End Sub Private Sub txtGuess_Enter(ByVal sender As Object, ByVal e As System.EventArgs) Handles
i 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?
I 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.
I 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
i want to set a default number and you type in a textbox a random number it should tell you whether it's high or low ,and when you typed in the right nmber it a lable should says something like you win .And also how can you change PART of a lable by typing in a text in a DIFFERENT FORM
VS2010 (SP1) / .NET 4 on Windows XP. The question is simple, the answer; not so much. When generating a salt, should the LENGTH of the salt be random, fixed or a random number within a (min/max) range? I am using RNGCryptoServiceProvider to generate the salt, just unsure of the length of the salt.
I 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?
I would like to create macro. I have some questions is something possible and so on. First thing is it possible to detect number on game? example: this line : Your next dig's number is 8327, type /dig 8327 to dig.I need to get that dig number and then it need to type F6 and type /dig number and enter.Its must do it every 30 sec.Is this possible to create one ? and anyone have ideas how to create on if it is possible.
I'm sure I'm doing something wrong; but this has been driving me crazy for a while now.I've made a small Silverlight game (an old Galaxian clone). When the game starts ~90% of the time, a bunch of stars are randomly positioned in the game area. There are three types of stars - bigger stars more faster, smaller stars move slower.
I am currently having trouble detecting the number of rows in the table in sql database. I have one column as auto increment, and one column that will show the blkname. But everytime I delete off one row, the program cannot run saying that there is no row at position "up to the latest number". Then, when I try to insert back the row again, the program also gives me the same error. I think the program probably cannot detect the number of rows correctly as it cannot like detect if there is 5 rows in the database and if you delete one row, it will give me the error. The above method is the same if I used the auto increament column and without.
The code that I have wrote so far is : 'AUTOINCREMENT Dim n As Integer Dim inc As Integer Dim numbers() As Integer Dim StartFrom As Integer Dim EndAt As Integer Dim MaxRows As Integer MaxRows = ds2.Tables("CustDetail").Rows.Count [Code] .....
I'm wanting to add a random number into a database but before I do this I want to check to see if I alreay have this number in there, How can I do a search to return a true or false I guess answer to if the value is in my access database?
[Code] What I'm having trouble with is that the numbers MUST be unique. So, only one 1, one 3, one 5, one 7. So I have it go through the second statements to randomize the object again if it's the same, but after it randomizes, I kind of need it to go back to the top to see if the number is even again.
I'm wondering how I would go about generating a random number in VB.Net. As I am developing an ATM system for a bank, a randomly generated 4 digit PIN code would have to be assigned to each person.
I 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
What I can't get to work correctly is the following. I have a textbox for the min and max. 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.
I want to create a Random number between 1 & 249 (including both numbers).The only Book I have MS Visual Basic 2500 Step by Step (by Michael Halvorson) gives codes as follows to display the result in a Label:label1.Text = CStr (Int(Rnd() * 10)) This is to get a random number between 0 & 9.
