Pick A Random Number Between X And Y?
Feb 4, 2009I have this code to pick a random number Between X and Y
X = Minimum Number
Y = Maximum Number
But the problem is i wanted to know if there is a better random function than the one i have.
Because right now i put
Min = 1
Max= 2
and it keeps picking 1
if i had min =1 and max =2 i want it to pick 1 sometimes and 2 sometimes
and now i tried min = 1 max = 3 and it never picks 3, it only picks 1 and 2
ok
Public Class Form1
Public Function RandomNumber(ByVal MinNumber As Integer, ByVal MaxNumber As Integer) As Integer

Randomly Generating Number (Price For House)
Feb 9, 2012I'm working with a random number that generates a price for a house between 1 and 100 dollars (obviously very realistic).
Dim Housecost As Integer = (Int((100 * Rnd()) + 1))
My problem is that I put that number in the public class which does generate the number but only once. But I need the number to be re-generated every time a button is clicked. Now I would put this code snippet in the buttons Sub but there are 3 other subs in the code that call for that randomly generated number and the only way that I know of that allows all the subs to read this random number is to put it in the public class. So how do I put the number in a place where all Subs can read it and can be called to re-generate when needed?

VS 2010 - Stopping Timer When Reached To Randomly Generated Number
Nov 27, 2011Basically I am trying to get my timer to stop when it reaches a randomly generated number.
I have dimmed num2 as integer (num2 is timer)
I have dimmed num3 as integer (num 3 is random number)
I have done num3 = randNum.Next (0, 8)
My timer is working perfectly and counts from 0 -8. My randomly generated number works too, so how do i get the timer to stop when it reaches the random num?
I have tried;
if num2 = num3 then
timer1.enabled = false
But that didn't work
Array - Randomly Generate Numbers
Apr 14, 2010I am making an application that randomly generates numbers. I then have to find out if those numbers are even or odd.

Display String Randomly From Array

View 4 RepliesCAI Program - Display Question "How Much Is _ X _?" With _ Being A Randomly Generated Number Between 0-9 - Label
Jan 28, 2011Basically, I'm not sure if I'm thinking along the correct lines when trying to break this down. The program is supposed to display the question "How much is _ x _?" with _ being a randomly generated number between 0-9 which I have in a label. The student inputs the answer and clicks the "Answer" button. If he gets it right, the label below outputs "Very Good!" and automatically puts a new question in the above label. If the student gets it incorrect, the output is "No, Please try again." and the student keeps trying until the question is answered correctly.
My method of thinking on this is that the random.object generator is input first so the question with the numbers are output in the first label. Then, under the Sub answer.button, enter the statements that will either check and refer to the above statements to get a new question or have the student try again until it's answered correctly. One of the other criteria for this is that I have to use a function for the calculation. Would the function statement, because it has to return a value, go before the answer.button code or after?
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.
Program - Requests A High Number And A Low Number From User - Searches Array And Finds All Elements Within Two Numbers
Jan 24, 2010I 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:
