Random Number Generate (within Range)?

Nov 30, 2009

The object of this project is to write a computer program that will allow the computer to guess a number that you have selected. The computer will make a guess and you, the player, will tell the computer if it guessed too high, too low, or that it guessed the number.The program will also allow the player to start a new game or to exit the program. PROJECT INSTRUCTIONS:

1. Create a form with a labeled box to display the computers guess.

2. Create a new game and an exit button.

3. Create objects to indicate if the guess was too high, too low, or right on target.

4. Create program code to respond to the player�s indication by selecting and displaying a new computer guess.

5. When the computer guesses the player�s number, reset the so that a new game may begin.

I have done all as above and so far my code looks like so

Public Class Form1
Dim Guess As New Random()
Dim HGuess As Integer, LGuess As Integer, current As Integer

[code]....

The problem i ran into is that if for example a user has a number 24, when the program makes an initial guess of 50,i want to be able to click low, and the program should generate a lower number say example 22. If i then click higher as my actual number uis 24, the program should not shoot higher than a number it has previously guess incorrect (in this case 50) it should guess anywhere from 22 - 49 and in turn limit the range of the next consecutive guesses it till hits the right number. My code right is guessing as it shuold but not within the limited ranges.

I am coding a lottery number generator for a homework assignment. My project needs to have functions that return random values based on a range given. The first function I am coding is for a pick 3 lottery game.The function should return three random numbers between 1 and 9. I have coded the function but it only returns one number. When the debugger runs it says my function does not return a value on all codepaths.

Nov 26, 2011

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.

Generate Unique Receipt Number In Certain Range

Dec 21, 2009

How would I go about generating a unique receipt number in the following range:
GA00000-GZ99999? I am not allowed to use the 'I' and 'O' letters so GI00000-GI99999 & GO00000-GO99999 would be excluded. Ideally, I'd like to create this in T-SQL but can also do it in VB.Net. This number will be stored in SQL and I can access it prior to generating the next one. They do not have to be sequential.

Generating Random Number Within Specified Range

Apr 7, 2009

I'm using VB.NET 2008 Express Edition and I'm trying to create a simple program that will roll a number of dice I choose. It does this by generating a random number within a specified range (I'm rolling 3-sided dice in this case so I'm generating numbers between 1 and 3) and adding each number to a textbox to create a total of all the dice rolled so far.

This is my
Private Sub butRoll_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles butRoll.Click
Dim RandNum, i As Integer
Dim RandomClass As New Random()
'if at least one dice is rolled
If txtD3.Text > 0 Then
[Code] ......

Now the problem I am having is that although my random number generator is generating the right numbers (confirmed by checking the txtLastRoll textbox), when I add it to txtTotal, it seems to be getting another number from somewhere and adding that to my random number then adding it to the total and I have no idea how this is possible! txtTotal always starts as 0 but txt1 is not showing that. Normally I would just set txtTotal to 0 there but if I do that, I won't be able to add the numbers together. I've tried finding a pattern in the mystery numbers appearing in txtTotal but they just seem to be random.

Generate A Random Single-use URL?

Nov 30, 2011

I've published a different take on a log in system on CodeProject [URL] and I've got some free time, so I thought I'd have a look at password recovery/reset.It was suggested on the article that I look into sending the account owner a single use, random url where they can reset their password if the account gets locked because of too many invalid login attempts/forgotten password.So far, I'm thinking I just have to generate a random string in a "recovery" field in the database table for the user's row and then check if the requested URL on the site is the same as the value for that field, then dynamically draw the page server-side.
