I'm working on a program that calculates 2 things. First I need to fill a 5 x 5 array with random #'s from 1 - 10 and Determine the average of each row, each column and the two diagonals, and the second calculation is Fill a 100 element array with random numbers from 1 - 100 and determine the standard deviation and mean of the random numbers in the array.
View 7 RepliesBeen trying to think out something for this one but i can't come up anything. Arrays is kinda tough for me.
I am trying to practice a program that:
1. ask the user for number of elements
2. Use IsNumeric Function to catch an error.
3. A 3rd form pops up showing random numbers like this:
0 45
1 23
2 56
3 75
4 34
5 99
Then, after i click a button called "Sort" It sorts the random numbers from lowest to the highest value.
Public Class Form1
Private Sub btnGenerate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnGenerate.Click
[Code].....
So as the name states; I am a newer coder.
This is the code i have:
Public Sub RandomNumbers()
Dim s(4) As String
Dim RandomNumber As Byte
I don't know if you can tell what I am trying to do here, so I will try to explain. I what to create for random numbers and place them into for different text boxes. I also would like to do this with combo boxes and their selected indexes. So if the combo box has 10 items in it; the new selected index would be the random number generated above.
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 4 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.
I have a datagridview with 3 columns.
Now I need to fill the datagridview's datasource with 3 arrays.
Example:
(column1) Username- Joe - Mark - Thomas
(column2) Password - Joe - Mark - Thomas
(column3) Activiated - Yes - No - Yes
Then after i split what should I do? Should I add 3 arraylists in a class or should I use structure and how?
My problem is that i am trying to use a list box to display all the data from one column in one table of my database. and so, i dont know how to do that although someone hinted at using an array, i'm just not entirely sure how also when the list of data is displayed i aim to have a 'select' button that will take the user to the record of the selected item from the box.
View 2 RepliesBasically, 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 port a program I wrote with old VB 1 and I have many control arrays in the program, and it was so easy to do this in older versions of VB, now I am trying to find how to do this and all the answers I have found are a major productions, to replace something that was so easy to do? I would think that microsoft would make programming easer with each new incarnation. instead they are making it harder. doing away with the DATA and READ statement, now it is much harder to fill an array with a loop, now you have to enter each item in an array ONE by ONE. they did away with the ON statement, I had several ON statements, I had to make complex Select case constructs. to replace a simple one word statement?
To make an array of controls in OldVB all you had to do is Name a Second control the Same as the First, and a dialog pops up and ask if you want to make an array, you click Yes, and that's it, what could be easier than this?
I guess I'm the newbie. I've just started trying to learn Visual basic 2008 express edition. I'm an old cobol mainframer and I'm having a hard time understanding this language. My project is to read a log file looking for claim numbers and I need to check that each claim has a start record and an end record. I need to fill up a dynamic array because I don't know how many claims there will be. The array needs to hold a unique claim#, a start claim flag, an end claim flag.

I have an assignment that requires me to create 5 different arrays: nouns, adjectives, verbs, prepositions, and articles. From those 5 different arrays, it has to display 10 different random sentences in the listbox named lstRandomSentences. The sentences have to be in the following order:
<article> space <adjective> space <noun> space <verb> space <preposition> space <article> space <adjective> space <noun>. Each of those arrays have to be randomly chosen in the list box and that's what I am having trouble outputting randomly.
how to do something similar to what was a control array in VB6 in .NET? I would like to be able to fill the contents of several text boxes using a FOR NEXT loop or something similar..... corresponding the contents of an array with the texts of an equal number of text boxes.

In the player vs computer tic tac toe game I've been working on there are 2 boolean arrays (one for the computer and one for the player) that track which cells have been taken. When all other moves have been exhausted I would like the computer to play a random cell. To do this I am trying to gather the indexes of all False values from the 2 arrays and add them to another dynamic integer array. The computer will then choose randomly from the new array. The two Boolean arrays are plyrTaken and cmptrTaken. The dynamic array is occupied.
Here I declared the arrays:
Public Class Form1
Private occupied() As Integer
Private plyrTaken(8) As Boolean
Private plyrPairs(14) As Boolean
Here I got the dynamic array ready for use:
Private Sub Form1_Load(ByVal sender As Object, ByVal e As EventArgs) Handles MyBase.Load
ReDim occupied(0)
And here is the code I have attempted:
For index As Integer = 0 To 8
If plyrTaken(index) = False And cmptrTaken(index) = False Then
ReDim Preserve occupied(UBound(occupied) + 1)
[Code] .....
In the last block of code I was just trying to print the contents of the array to a list box so I could see if it was working. Obviously, it's not. When one position is occupied the list box shows the occupied cell index with a Zero. This really shouldn't be there as I want only taken cell indexes to be sent to array and list box. When a second position is occupied 7 zeros are added to the list box. Kinda shows promise as 9 total cells - 2 is 7 but there should be index numbers other than zero to represent the cells that have been occupied.
Also, the indexes shouldn't keep adding on to the dynamic array I need a way to clear the array and resize it back to 0. I tried adding
Redim occupied(0)
to the top of the code but that didn't seem to work.
I'm trying to create a program that produces random sentences as output. With five arrays of strings, one each for nouns, adjectives, verbs, prepositions, and articles. Each array should hold several words for that part of speech. Like, the Articles array could hold the strings "the" and "a"; the Nouns array could hold "Martian", "baby", "skunk","computer" and "mosquito"; the Prepositions array could hold "around", "through", "under", "over", and "by"; and so on.
It's supposed to generate sentences by randomly choosing eight words (randomly generating eight array indices) from these arrays, always constructing sentences by using the parts of speech in the following order: article, adjective, noun, verb, preposition, article, adjective, noun. Also, the code should be properly modularized so that the code to generate each part of speech is not repeated.
I have to make a program that uses 2 arrays, one with the states name and one with the capitals names. I have to make it to where it randomly selects a state and asks you what the capital is, and gives you 4 choices in the 4 radio buttons provided. My problem is getting one of the randomly selected answer choices to be the Correct answer.
Here is my code so far:

I have learnt how to create a basic random word generator. I now want to take this further but I would like to know if what I am thinking of is possible. I am in the process of wanting to create a random name/word generator which reads/loads an array from a text file. think this part I will be Ok with as there are some vids and tutorials about. However, I wish for the text file to have multiple arrays and then dependant on the day and time of the day, only a string from the current time array is loaded. Does that make sense and is it possible? I am happy to spend time learning how to do this but only if it is possible.
View 3 Repliesi 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

I'm working on a program and in it I need to store all combination's of the numbers 1,2,3,4. I would like each combination to be it's own array, and instead of creating 24 different arrays (there are 24 different combinations 1,2,3 and 4 can be arranged) I was wondering if it's possible to create a nested array like so:
[ [1,2,3,4], [1,2,4,3], [1,3,4,2], [1,3,2,4] .......]
That way, I'd be able to reference index 2 of the above array and have the array [1,3,4,2] returned.I looked into multidimensional arrays, but this would require me calling each index of the row and column.I also looked into making a Structure in which there was an array that could hold 4 numbers, but wasn't sure if going that method would be practical or not.

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?
