View 6 RepliesRandom Number Generator Generates Same Numbers 19 Times Out Of 20 ?
Apr 1, 2010I 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()

Program That Generates Random Numbers For A "Lottery"
Oct 15, 2011Making 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.

View 6 RepliesGenerates A Random Password And Store The Value To A Label
Apr 18, 2012I 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.

Computer Generates A Random Number Then Checks It Against Users
Feb 15, 2011I'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:

Make An App Where Computer Generates A Random Number Using A Function?
Nov 25, 2010I'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...

Program That Generates A Random Line Of Text From A .txt File

Generates A Random Number And Validates The Users Guess To See If Its Correct?
Jul 31, 2010I'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."

Use .next (random Numbers) To Randomly Select Something From A List Of Numbers But It Can't Repeat The Number?
Aug 16, 2009So how would I use .next (random numbers) to randomly select something from a list of numbers but it can't repeat the number?I could do:
dim num as integer
dim r as new random
num = r.next(1,5)
if num = 1 then
elseif num = 2 then
etc.
That wouldn't work because it would repeat.If I donwload someone's game can I disect it in VS? :0 I tried going to open project, then I went to the folder and clicked open. It brought me inside of the folder so I tried to open the game but there is no form1 there. It says the games name then .exe in the explorer-like thing in the top right?Also, how would I have a value or something in a label and access it from a button.
Example:This is in a label.
Dim number as Integer
number = 0
Then in the button do
Label.number = 0
How would I do something like that? I want to use that a lot as I did in a different language.
