VS 2008 Random Number Generated Is The Same Almost Everytime?
Jul 26, 2010
I've got a global random type variable, let's call it rRandom.In my code, I generate a random number like below:
Dim iRandom As Integer = rRandom.Next(0, x)
9 out of 10 times iRandom is 0, the other time it was 1. The code isn't on a timer, it happens when I do something (say clicking a button), so the frequency of the code being called is about 2-3 seconds, I say this because I've had similar issues when generating random numbers really fast in a timer, or with a for loop IIRC.X is a variable that, presently, starts at 3, and will decrease until 0, in which it'll return back to 3. Obviously, if X is 0, iRandom will be 0, but it shouldn't be 0 all the time.I'm declaring the variable globally because I remember, again, having similar issues using local variables, idk whether I should be or not.
Right so my generator is working, but I now want to take the numbers that it generates and add them to a list of generated numbers. So you can monitor what numbers have been generated. then ideally a way to exclude these numbers from being generated again.
I am using some arrays that are pre-filled and I am having a random number generated between 0-10. That random number will then go in to all 5 arrays and pull the item from that location. I think try to take the sentence that is generated into another string. Once that is complete I then go through the final array to pull all the sentences and concatenate them together.
Currently I've only been able to get 1 sentence to print out of 5...a fresh pair of eyes would prob see where I am going wrong...I've been at this for awhile and wouldn't mind some advice to where I am going wrong.

I am trying to generate a random number during testing using NUnit, but it keeps generating the same number. I am using the following function for this purpose.
dim dCount As Integer = Math.Floor((High - Low + 1) * Rnd() + Low) dim divName As String = "abc" & dCount
Beginning VB 2010, had a project that requires us to create a list box of 25 randomly generated 0s or 1s. Problem is when I put the loop in, it only repeats the same random number, not different one each loop. What am I doing wrong?This is the code I have so far...Code in Question:
'Declare new random object Dim RandomGenerator As New Random intRandomNumber = RandomGenerator.Next(0, 2)[code]......
the goal i want to accomplish is when the user presses a button, "moneyamount" increases by a random number generated. the problem i am having is that after the action is finished the script does not seem to save the new value and always starts at zero. here is the script:
Private Sub button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles dojob1button.Click
Dim moneyamount As Integer = moneyamount + Int(Rnd() * 10) moneylabel.Text = "$" & moneyamount End Sub
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 generating an array of random numbers for for a class project (simple yahtzee game)I am comparing the output of the array and displaying a picture of each matching dice in a picture box.I would like to use check boxes to select a position of the array so it cannot be changed until the check boxes are clearedWhen the check box is checked, the value of the position in the array should not change.
I have a Application that uses proxy IPs. I have a List of 100 ips, adn i want to take a random proxy and use that each and everytime whenever a button is clicked. I got the Proxy code and i modified it as below.
Imports System.IO Public Class form1 ' The structure we use for the information ' to be interpreted correctly by API.
[code]....
It successfully give random results but when i use webbrowser to confirm proxy ip, it shows only 1st or 2nd ip for every time. but i am getting random ips in listbox. When i click button it will get random ip and make browser to navigate to that ip and later it will add it to listbox.
Possible Duplicate: Get year and month from SQL .I want to know that everytime I change the month the tracking number will start at 001 ..For example this is my tracking number:
CAB1108072 == CAB + 11 for year, 08 for month of august, 072 running number
Do I need to have another column in the table for the month in order to generate the tracking number everytime the month changes? The output should be like this.Example:
August 31, 2011 running number is 072 tomorrow is september 1st i need the tracking number start to 001, because september is another[code]....
I have a code that generates random code using a set of letters. One for a random pin and another for a random code. I can loop the generation of my codes depending on the input. When I try to generate 1 to 3 set of codes it works fine. but if it's 4 and above. I always get a duplicate set of random numbers. I don't what wrong. My code for generating my codes are in vb.net and be passed to a stored procedure for inventory.

I am currently enrolled in the class. My final project for the class will generate random numbers within a range of numbers. For example, if I give the user five text windows to choose whether to input a number OR generate a random number, I will have a button called RANDOMIZE. Unfortunately, I do not know the line(s) of code for the random function.
vb ...Dim random As Long = RandomNumber(1000000000000000, 9999999999999999)... Private Function RandomNumber(ByVal Min As Long, ByVal Max As Long) As Long Dim Random As New Random() Return Random.Next(Min, Max)End Function
...I am getting a OverflowException. Is it so that Random class can't handle Long values?
I want to create a random number with the combination of the text entered in textbox. Suppose the textbox contains bharani. So now the random number generation is the first 3 letters from textbox and the random number from 1 to 1000. So my output must be "bha876"
I was before knew how to code that it will give me a random number! Also i know it was 2 ways i could make it. A range from like 0 to 100 if i want that. And then it draws a random number from that! And i knew another there i could type in the numbers and it draws a random from there.
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've ran into an overflow error when using a private sub and a random number generator...
Private Sub computerpicker() Dim RandomNumGen As New System.Random Dim rnum = (RandomNumGen.Next(3)) If rnum = 0 Then rnum = (RandomNumGen.Next(3)) Call computerpicker() [Code] ..... Even if bt1=0 and bt2=0 i still get an overflow error...
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 have an app with 4 buttons that each generate a random number into textbox, before this number is entered i would like to have a progress bar at the bottom, well show that its processing basically.
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?
