i want to get a random number from an integer array, then delete that number in that array.for example, i have an array like this {1,2,3,4,5,6,7,8,9}now i want to get a RANDOM number in that array ( the number must be in the array), 8 for example. And then delete it from the array.
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
Public Class Form1 Dim i As Integer Dim V0(9) As Double
I cant seem to see what is wrong with this arrary size. It works if i set the random number to 10
pretty sure it's to do with this line For i = 0 To intResult but i cant for the life of me figure it out.
Dim intResult As Integer '// Initializes the random-number generator, otherwise each time you run your '// program, the sequence of numbers will be the same
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'm converting a user generated list box to an array and then generating a user defined number of random strings and placing it in a textbox.The code I have works fine as it will generate the number of random strings the user wants, except sometimes a line is blank at the top of the list but is counted as a string.
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?
im working on a project that is calculating the total population for given countries and its in the hundreds of thousands. And i need to output the population with the ,'s in the appropriate places.Ex. population 123456789 i need to output it in a listbox as 123,456,789 so im looking for a converter function or something built in that takes my value
I am trying to think of a possible way to insert a colon and decimal point to a part of a number. I am making a Rubik's Cube timer, and I converted the times to milliseconds so I can calculate the average of 5 with that. I averaged the milliseconds, but now I need to convert that into minutes, seconds, and milliseconds. Does anyone have any idea on how I would go about this?
i do have a table with 3 cols, 2 of those will visible for users to enter data, the last one is needed to get inserted as the next number of the previous number.
i use the following query for insert command ,
INSERT INTO [Headers] (GrpId, GrpName, Number) Select (Select Case when Max(GrpId) = Null then 1 else Max(GrpId)+ 1 end from [Headers]),
Have the following code which creates a table of all the images in a folder.[code]What I want to do now is group all these by the first two characters and get the total number for each and insert them into individual strings. So for the above example it would be something like:[code]

I have a 2 dimensional array and also a 2 column listview box. I am able to insert array (0,i) into column A, but i do not know how to insert Array(1,i) into column B.
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 need to write a program that requests a high number and a low number from the user, then the program searches the array and finds all elements within the two numbers. The program is used to search for past presidents, so if I type 43 for low number and 44 for high number, the program will display:
George Walker Bush Barack Hussein Obama
I think I have an idea of how to search up to a certain point, but not to stop at a certain point....Here is the code that I have for that particular sub procedure:
