Make An App Where Computer Generates A Random Number Using A Function?
Nov 25, 2010
I'm supposed to make an app where computer generates a random number using a function and then the user has to guess the number. If they get it right, they see a picture.... If they get it wrong the loop keeps going until ten guesses are up.. I'm running into quite a few problems...
1. I don't know how to tell if the photo will show up if the number is right because right now I have it set to false in the form, so it dosen't show up but in my loop I included the code that SHOULD allow it to show up if both numbers are the same.... Not sure if this is correct...
2. I have a textbox that is supposed to keep track of the number of guesses but the message automatically becomes Game Over and the guesses go up to 11 as soon as I click the Are You Right Button?
3. When I try to debug, my app freezes and I don't know why...

I'm Trying to make a piece of software where You enter a number and the computer measures the length of the number, and then generates random numbers to match the human number. It will then count the number of guesses and the time taken. However it always comes up that there was a infinite loop "An unhandled exception of type 'System.StackOverflowException' occurred in System.Windows.Forms.dll". I have searched up how to do this and I can't seem to find out how. I think I just put my wording wrong when looking it up. My Software Has Has 2 TextBox, 2 Buttons, 6 labels (4 just to make it user friendly) and a timer.
Here is the Code:
Public Class Form1
Dim TimeTaken As Integer
Dim GuessesTaken As Integer

I am trying to write a random number function that can just be called from my main module to generate different random numbers. I have tried this several different ways and I am having odd results. Approximately 19 times out of 20 the numbers come back exactly the same, but approximately 1 in 20 they come back as two different numbers. Im using Visual Basic Studio 2008. Here is the code I have so far, or rather, the current version of my many tests I have been running to try and figure it out. Sometimes it takes many runs of the program before the two seperate numbers apear.I've been researching it and have come up with nothing so far.I know I could put them in the module section as two different randoms and it works, but I get extra points if i use a couple classes in my program.This is the main module.
Module Module1
Sub Main()
Dim randomNumOne As New RandNum[code]...........

I've created code that generates a random number and validates the users guess to see if its correct. I think the code is good but i'm not 100% sure. I need to add additional pieces to the code and i'm not sure where or how to do it. allow the user 10 guesses. after 10 guesses disable the ability to make more guesses if the 10th guess is wrong count each guess entered & display the count as it increments display each guess along with its returned messaeg into a list box. when the user gets correct answer provide a box to allow them to play again. Re-initialize variables back to their starting status.
a. If the user correctly guesses the number in less than 5 guesses display "Either you know the secret or you got lucky!" in a message box. b. If the user correctly guesses the number in 5, 6, or 7 guesses, display "Ah Ha! Do you know the secret?" in a message box. c. If the number of guesses is 8 to 10, then display "Try to do better next time." d. If the number of guesses exceeds 10, then display "You have taken too many guesses."

I'm trying to make an application where when the user clicks a button, it generates a series of 100 random numbers between 1 and 1000, and then saves those numbers in a text file. All I could come up with is generating ONE random number, but I can't figure out how to make it 100. Here is what I have:

I am making a program which generates a random number between 1 and 10 and when 7 appears it is suppose to tell you how many tries it took to get the number 7 and then end the application. This is the code I have used:
CODE:
This code only generates the number 7 and exits the application, each time i click the random button but i want it to show the other number it randomizes too for example 1 2 3 4 .. etc, if u dont understand, please try it, but im trying to say, when i clikc random it just says number 7 (does randomizing in background) and tells you how much tries it took but i want it to show the other number it randomized also and when 7 appears, then exit the program

I've got a random number function that generates 3 random numbers between 0 and 10. I was just wondering if there was a way to exclude the value that was found before it? For example:
Random(0) = Int(Rnd() * 10)
Random(1) = Int(Rnd() * 10) 'Here i want to keep it as 10 values but exclude the value of Random(0)

I'm trying to create a function that can be use to generate random number but with percentage.For example, random number between 1,2 and 3.For 1 = 30%, 2 = 50%, and 3 = 20%I will use that function in mini games that I will create. I've tried to search but I cant find one. A function of vb.net random() doesnt have percentage right?

I need to use the randomize function to generate a random number between 1 and 50 for lblNum1 and lblNum2, ensuring that lblNum1 is greater than lblNum2, otherwise the randomize function needs to run again for lblNum2. I need to ensure that the user has selected an option from the gbCalcType and cboGrade first, and then the randomize function should run when the user clicks the button named btnBeginGame. How do I do this? I have this so far that generates the random numbers when the btnBeginGame is clicked:

I have the following code which extracts the contactcode from a table in a database;
[Code]...
Code: lblUniqueID.Value() = (RandomPassword.Generate(4, 6)) Now, I want to compare the contactcode values extracted from the database and the value stored in lblUniqueID.Value(). If the random password is similar to one of the contactcode then generate another RandomPassword IF NOT then place the value to another label called lbltransfer.text.
I'll insert that value to the database.. The idea is extract all the contactcodes(these are the random passwords already generated and stored) from the database. Compare with the new generated password if it exists then create another one if not then store it in a label called lbltransfer.text.

Anyway, I'm primarily a web developer so I'm only really fluent in PHP and everything else it entails.For my assignments the examination board suggests Visual Basic, so I'm just needing a little help as I'm not too great at it yet. [code] How could I ensure it generates a number 1-13 BUT doesn't ever generate a certain number, e.g. generate a number 1-13 but NOT 7.

I got a little program that generates a random line of text from a .txt file and all is working well, at least for the most part.
On occasion I get an error message popup saying "Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: Index."
Here's my code:
CODE:
The last bit is where the random number is generated, which I am guessing where the problem itself is, but am unsure as to how to fix it...

I have a function called DieRoll. In the function I have the following setup.
Dim objRandom as New Random
Dim intRoll as Integer
intRoll = objRandom.Next(1,7)
Return intRoll
Everything works as expected as far as generating a random number (1 - 6) is concerned, except for one problem. If I have a series of calls to the function one after another, the numbers come up the same. Is there a way to make sure that each call to the function is much more random?

This is probably a stupid question, but how do you make a function which takes a number then does an operation to it again and again until it gets a vlue which it already has seen, when it returns all of its values? I have this function:
Private Function fractal(d as string) As double
Fractal = Val(D) * (Val(D) - 1)
Fractal = FormatNumber (Fractal, 2)

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]......

Making a program that generates random numbers for a "Lottery" (really for homework). Four different types of games and must show up on the GUI when click generate. My question is do you have to have different dim randomObject As New Random() for every Sub to produce different numbers? Every single type of game has different range of number. The Sub needs to return the results back as a string. If I request the method each time will I get a different number back from the range? Here is what I have but just so lost.
Public Class LotteryNumberGenerator
Dim randomObject As New Random()
Private Sub genButton_Click(ByVal sender As System.Object, ByVal e As
