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 RepliesDoes anyone know how to do the following:Get a string with with random characters and numbers in it?I want the string to be 6 characters long.
Basically, when a button is clicked, i want to fetch random letters and numbers and assign them to a string.
Is it possible to immediately use code that is built in a dynamically built assembly?I would like to create an instance of an ENUM built using.http:[url]......
View 4 RepliesI'm new with VB programming and would like to know if anyone can look/test this code I have written. I don't have the ability to test right now because I'm at work and can't get VB installed on my desktop. This program is supposed to display the amount of gross pay for employees based on their weekly sales (if $5000 or more times 9% + $200) while using a one dimensional array.
View 2 RepliesWith 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?
The 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 11 RepliesSo 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.
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 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]

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

View 12 Repliesi have a few questions about generating random numbers:1) is it possible for the programme to generate a random number that it has previously generated (i.e could it produce the same number more than once?)2) can you specify what numbers to generate? e.g only whole numbers up to 1000?
