I want to set an array upperbound limit to 50. I need a loop to create a random number and place it in the array until it reaches 50( I've set up the random generation part). My question is do I set the upperbound limit when I create the array and redim for each sample being added or set the limit somewhere else? I understand how to set up a basic array and how to redim arrays, but adding the loop to it is confusing me.[code]...
I have made a function which opens a random image, but sometimes I get the 'Index out of bounds of array' error. VB Private Sub OpenRandomImage() Handles mnuOpenRandom.Click If FolderBrowserDialog.ShowDialog <> vbOK Then Exit Sub Dim Path As String = FolderBrowserDialog.SelectedPath Dim BmpFiles, GifFiles, JpegFiles, JpgFiles, PngFiles As Array BmpFiles = IO.Directory.GetFiles(Path & "", "*.bmp") [Code] .....
I cant seem to see what is wrong with this arrary size. It works if i set the random number to 10
pretty sure it's to do with this line For i = 0 To intResult but i cant for the life of me figure it out.
Dim intResult As Integer '// Initializes the random-number generator, otherwise each time you run your '// program, the sequence of numbers will be the same
I have not messed with VB much and I have been trying to do something that has me stumped. I wanted to create an array of 10 random numbers. Each of these numbers then is printed onto a label. From here I have two more labels that show the highest and lowest value. I got the first part, 10 random numbers show up but then things get shaky. This is what I have thus far.
The first problem I am having is that it populates every cell with the same random number. How do I get it to create a new random number? The second problem is that I need to make sure each entry in the array is unique.
I'm trying to make a Bulls and Cows type game, I was able to do it fairly easily with javaScript, but VB is killing me. I can get the array 5 slots long with random numbers, unfortunately they're all repeats. when I try getting no repeats I run into infinite loops, exponentially increasing array lengths, and just plain old arrays with 5 numbers randomly generated, but with repeats.
I'm trying to do this with loops, in JS I did it using regular expressions
Here's an example of my code.
Public Class Form1 Dim intRand(0) As Integer Dim RandomClass As New Random
I am writing a program for a class on visual basic and i have a listbox that displays 15 random numbers using an array. Then there are 2 buttons(max and min) that when clicked displays the largest number in the list and the smallest. how do i get these buttons to do this?
I'm new to the forums and VB programming in general, so I only have a very basic understanding of VB commands, but I still have a good grasp on logic and the like. I'm doing this for a school assignment, and I am in a bit of a pickle.I am trying to generate an array of 6 random numbers from 1 to 30, making sure there are no duplicates.I think I'm pretty close to cracking it, but it still doesn't work.Here's what I have at the moment:[code]......
I'm creating an application that creates a list of 20 ramdomly selected numbers within an array and displaying those numbers in a listbox. I then need to display the duplicate numbers in an adjacent listbox by clicking the find duplicates button. How would I be able to access those 20 numbers in order to find the duplicates?
i want to generate random numbers which will be put in an array and displated in a grid. the user has to provide a lower and upper bound. method overloading also has to be used in order to generate the numbers
My project is basically a addition test for 5 to 9 year old children. On my form I have a button which when clicked, it inputs a number from 1 to 10,( which is chosen by the user via an combo box drop down), into ten text boxes. I have built and array and used a, for loop for this and it works fine. [code] My problem is I need to create another array connected to the same button to genarate 10 random numbers. Which will allow the user to add the two numbers together.My problem is that visual basic wont let me add a second array to the same button?
How do I go about doing this? I have currently made this code, but sometimes points are created on the boundaries of this picture box, which I do not want. I want all new random points to be within the bounds of this large playarea (picturebox). Foodarea is my big picturebox which i want all fruit to spawn WITHIN not outside on it's edges.
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.
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.
Public Class frmMain
Private Sub btnExit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExit.Click
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 keep getting "Index was outside the bounds of the array." error when I run the exe from Debug and Release, but if I put my parameter -dev in a shortcut I do not get this error.Here is the code causing the problem
Dim cmdLine() As String cmdLine = Environment.GetCommandLineArgs() If cmdLine(1) = "-dev" Then 'problem[code].....
At the line `If aryTemp(1) < aryTemp2(1) Then the Index was outside the bounds of the array.
error appears. Can't identify why would it be outside array's bounds. Basically trying to compare Last Names to sort the records and place em back into list box.A student record looks like this: FirstName[space]LastName[space]Major[space]Telephone[space]Email[space]GPA
Every time that to form loads, the tab control loads all information for each element in the array into the tab controls at once, instead of stepping through Error says index outside of bounds of array
