I need to generate random strings in vb.net, which must consist of (randomly chosen) letters A-Z (must be capitalized) and with random numbers interspersed. It needs to be able to generate them with a set length as well.

I need to generate a lot of random 2 character strings for my application. it's a VB console application. basically what I have tried for random strings is this:
Private Function GenerateRandomString(ByVal intLenghtOfString As Integer) As String
'Create a new StrinBuilder that would hold the random string.
Dim randomString As New StringBuilder
[Code]....
What is going on? I thought that I used to, a long time ago, be able to just do random.Next.
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]
View 3 RepliesI don't take programming lessons at school or anything, and I'm starting to (try to) teach myself about random things.Currently I'm making an app that has 3 functions:
-Random Integer (1 to 100)
-Random Answer (Yes or No, similar to a coin flip)
-Random Dice Roll (1 to 6)
How would I go about doing this?At the moment all I know about random numbers etc. is that I will need to do something along the lines of Dim dice As New Random or something like that, but, like I mentioned, I have no idea.I am well aware of the DIC rules that you won't write the code for me/do my "homework(?)" for me, and that's not what I'm asking.
'm attempting a program and need to generate 10 random numbers between 1 and 52. However all the numbers must be different. I'm trying this in a For Loop. I'm not terribly amazing at this so all I have so far is:
Dim B, I, J, max, min, card() As Interger
max = 52
min = 1
Randomise()
[Code].....
What am I doing wrong and what is the ultimately simple solution I know the internet can provide for me?
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.

I need to generate 'real' random numbers from 0 to 500 (e.g. 247.214, 477.125, 1.247, 54.078, 147.001 ......etc). I am using this method:
Dim Myrand As New Random
Dim Res As Double
For i = 1 To 10
Res = Math.Round(Myrand.NextDouble, 3)
Next
This method gives numbers between 0 and 1. if I use: Res = Myrand.Next(0,500), then this gives Integer numbers.
The questions is: Is this possible with (Dim Myrand As New Random) or I have to try another way (e.g. Rnd() ) for doing this?

View 6 RepliesI know there has to be a simple way to do this but I'm not sure how the syntax would go. I need to generate a random number from 1 to 99. How do I do this? I have my attempt that failed below:

I have an application that is made for a game that you have to draw cards for. So what I have done is created a random number generator that generates a random number and then using case statements that number is associated with a picture of the card, which is displayed in a picture box. This part works fine. Each time I draw a card it is not reshuffled so I need to store the random number generated and then if that number is generated again ignore it an generate a new number.
Now to complicate matters even further when a certain card is drawn the entire deck is reshuffled and everything starts over again. Here is what I tried... I tried using arrays to store the numbers but I cannot seem to get it to search the array for the number or store the number properly within the array. The array has to be dynamic since the game is expandable and I will be adding more cards to the game in the future.
i would like to generate some random number with some alphabert inside.

View 1 RepliesThe 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.
