Basically, when a button is clicked, i want to fetch random letters and numbers and assign them to a string.
I'm about to make verification code to my app it would be built out of random characters and numbers,i have no problem making a custom one,but before i go and do it i just wanted to ask if there is built in method of such thing .NET environment
View 3 RepliesI am trying to do a turn-based battle. I want enemyhit to be a random number between enemyminhit and enemymaxhit, and I want playerhit to be a random number between playerminhit and playermaxhit. The numbers are random, but my problem is that enemyhit and playerhit always seem to be the same, or close to the same.

i'm programming sudoku game for my vb 8 class.but i don't know how to generate random numbers, i think that i've to use random or randomize, but i don't know how to use them, i've been looking around but i can't find an answer.and i only have this week to program it
View 10 RepliesI am trying to write a program that gives a random number with out repeats the limit is 60 right now. I get a System.StackOverflowException error randomly sometimes it could be 5 numbers in it could be 50. also it will repeat some numbers. Ive been looking over it and it looks like it should work to me idk why its not.
BTNgen calls this sub.

What would I put when I want it to generate random numbers and text, and has a - at the end. I know it's pretty simple but I can't think of how I would do it.
So 5 random numbers/and or text and a - at the end. So like this

View 1 RepliesI have a program I'm working on (a chance game) that has 5 random numbers generated. I need to think of an expression to check to see if three of those numbers are equal. The random values are not an array, they are 5 separate variables. I have the code written to compare if there are two matching ones, but am having trouble thinking past that. [Code]

With the shape of really large characters such as numbers and alphabetic characters + others, is there a way to get that shape as a REGION please?Imagine a really fat snake forming the letter S or two rectangles placed together to form a large letter L or a T like the shapes in TETRIS.
1) Does anyone know of anything in VB.Net that can translate such shapes into a System. Drawing.Region or know of a project elsewhere that achieves this please?
2) While I'm on the subject, how would you SCALE UP / DOWN a System.Drawing.Region please? How would you work out the Transform Matrix required please?
How can I make a command button, When clicked, Generate 4 random digit numbers? such as 5545 or 7492, Any random 4 digits.
View 13 RepliesThe class Random is out right defective. It always produces the same random numbers in the same sequence. Things I have tried so far is every kind of seed you can think of as well as Randomize. The result is that I always get the same random numbers in exactly the same sequence.
View 4 RepliesI'm trying to make a program that'll play the card game "War". I've started to code the dealing process, but it doesn't seem to be working. I currently have 3 comboboxes on the form each with numbers representing different cards, 1 that contains all the cards to be dealt, 1 that contains the user's cards, and 1 that contains the computer's cards. I plan to just draw random numbers from these comboboxes for the dealing. However, nothing happens when I click the tool-strip button that's supposed to deal the cards. [Code]

Is this possible?
Right so my generator is working, but I now want to take the numbers that it generates and add them to a list of generated numbers. So you can monitor what numbers have been generated. then ideally a way to exclude these numbers from being generated again.

So 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.
The program must generate 6 unique random numbers but when I click display numbers sometimes it gives me 6 unique numbers and sometimes I get duplicate numbers. I will add the code I have so far.

I 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.

For each character of this string I want a new character out of the string and then remove the character from the list of characters that still maybe used for other characters. It may not get the same character, you could basically just call this encryption, but it's not what I am making. I don't want to waste my time doing this one hour while VB can do this for me in <1 second.
Basically, I want to divide two numbers together and they should be 2 random numbers from 1-12 (I have done that part) but, the answer should be a whole number (i.e. Integer, so no decimal points etc) So, I did the following:
' Initialize the random-number generator.
Randomize()
' Generate random value between 1 and 12.
Dim value5 As Integer = CInt(Int((12 * Rnd()) + 1))
[code]....
but the problem here is that the program crashes after only a few clicks on the button. So I guess the question is: How can I make the program generate two numbers (from 1-12) that when divided become a whole number?(Is there any code that may tell the random generator that I want the numbers to be even?-so all even numbers from 1-12?)
i have errors while creating

i want to know how to generate 7 "differents" random numbers.
I need to use a tab() with 7 entries and verify(with a loop?) if the generated number is or not present in the the table, if not then increment a counter by 1 and add the number in the table and increment the table position by 1 for the next randomized number.
Im not sure how to do the verification, so far all i have is a function i made for the random number between min and max:
Private Function randGen(ByVal min As Integer, ByVal max As Integer)
Dim random As New Random()
Dim i As Integer
