Randomize Order Of Numbers In Listbox When Button Is Clicked?
Feb 10, 2010
I have a listbox with numbers from 1-10..i have searched it up but i cannot find how to do..how can i randomize the order of the numbers in the listbox when a button is clicked? (each number must and only occur once)
so I am working on a program with items entered into a listbox. Then when the user clicks a button it will randomize the listbox items in just a random order obviously. I have tried adding it to an array and everything but I ended up just having to start over now because I couldn't find a solution. I can save the contents and everything I know how to do that it's just randomizing the items that I am struggling with. I have searched high and low and have yet to find a conclusion to my problem.
Is there a way to randomize the location of a button? I am making a "Button Game" that is a kind of guessing game.The user clicks one of three buttons on a form, and if it is the correct button, then the next form shows, which will be level 2. I pretty much got all of the code down. Now, though, when I debug and run the program, I noticed that everytime I reopened the the game, the buttons were in the same order.So, if the user plays the game once, closes the game, the buttons are still in the same order, and the user knows how to beat it! That kind of makes the game boring to play because the user knows where everything is.Is there a way to randomize the order of the buttons?
1) When displaying text in a label with autosize=false, is it possible to display as much of one word as possible until it gets cutoff. Right now, if one word is longer than where the end of the label is set to, it won't display any of that word.
2) Is it possible to implement a down/up button that when clicked will scroll the listbox either down or up. I'm thinking of having the button change the selected index +/- 1, but will the view of the box scroll with the newly selected items?
I am trying to conduct a research experiment using a psychological measure. Basically its a bunch of words and you need to specify a value for (1-5). So, what I did was take a numericupdwn box and a label and paired them up using a panel. I did the same thing for 19 other sets. I placed each one carefully on the grid, nice and neatly, however I need to randomize the order of how they are arranged.
I spent hours trying to figure out how to set the location point for a panel. But to use variables through a random number generator, is simply too difficult!
How would I go about changing the color of a line of text in a Listbox when the user clicks a button? I have tried using ListBox1.Items(ListBox1.SelectedItem).Forecolor = Color.Gray, but I receive the error "Conversion from string "Mathematics 1" to type 'Integer' is not valid."
I gotta finish this application. When the "Enter Numbers" button is clicked, the application displays an input box for the user to insert an integer. After the number has been typed and the OK button is clicked, the application is supposed to give out the sum of all integers from 1 to the value entered by the user. Example: If the value entered is 5, the sum will be 15; if it's 10 it'll be 55 This is my code but something's obviously wrong, it is maybe in the loop?
[code]...
The result I get for 5 is 25, and for 10 is 100!Also, could you tell me how to display the result in a message box?
Say I am pulling the following table, I would then like to select an ID randomly. I understand how to select a random number using a Randomize() call followed by the relevant syntax but I want to pre-define the range.
i.e. Table Data ID | Name 4345 Mike 3456 Lee 4567 John
There will be many more names but for this example you could use 3 or 4 etc..
I'm trying to shuffle a Euchre Deck and it works but I feel like I'm cheating. Is there a more concise way to randomize a list of numbers 1 - 24 and have no repeats? ex. 14, 3, 18, 23...
Dim Deck() As String = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24} Dim A As New Random Dim B As Integer = A.Next(0, 24) Deck(B) = "9 of Clubs"
The goal is simple... generate a set of random numbers with a certain range (e.g., 1-6, 5-10) with no repeats. I tried using a system with arrays where everytime a number has been generated, its marked as "used" and then the program is required to generate a new number. But it doesn't work!
Public randomnumgen As New System.Random Public randomnum As Integer Public iCounter As Integer Public GotIt(7) As Boolean
am writing an system application for a company that must generate inquiry id and order id automatically. Whenever a customer makes a new inquiry or new order by clicking the add button, an automatic number should be displayed in the text box and when it's saved, it should be saved in the database access.
I am making a random name generator. what I got is a large list of first names in listbox1 and a large list of last names in listbox2. when I hit a button, I am randomly pulling a name from both listboxes and putting them into 2 textboxes. for some reason they arent always random. I would say out of 50 names I will get 2 or 3 sets that are identical. why??keep in mind I probably have 400 first names and 200 last names. I should never get a duplicate! here is my
'randomize first names Dim rnd As New Random() Dim randomnumber As Integer = rnd.Next(1, ListBox1.Items.Count)
im helping a school run a Spelling Bee aimed at children in year 7. And to make it fair and unbiased i need an application that can choose randomise a word from the list box then transfer the string to the text box.So basically something that can pick a random string from the listbox and show it in the textbox1.text property.
I click to textbox which have a string.How can i determine what character i clickd to it ? Example : That string is " I am Ann".I click coordinate contains "m" character. How can i know i click that character.
I got the textbox and a listbox and a button, I can add names threw the textbox hit the button to add and it adds to the listbox, now I need to take the names from there and randomize them into 4 groups and make it into an array also, I just dont know how to take the names I entered and randomize them and put them into 4 different groups without repeating themselves, it is ok if three groups that have 5 and the fourth has 6. They just need to be randomized and put into 4 different groups,This is what I have, but I think its the wrong way to do this, to make the code work right atleast.[code]
i am in need of some help getting my code working correctly like i am needing it to. Below is my code that when the user click on the textbox, it pops up a keyboard where they can click on any letter and it will type that letter into the textbox. Problem being is i can not seem to get the name of the text box to return so that it knows where to send the letters to.
I cant figure out the code for vb.net that would randomize the interval of a certain timer. For each a = a + 1, there would be a different interval, and for each a = 1, a = 2, a = 3 etc. there would be a different text that will be shown on a label.

how I can change the order of numbers. for example i have 147, how would i make the out put to that 741? anther example 24, Then I would want 42. or 542 -- 245.
What I am trying to do is re-order the numbers in my rows in my first column in my list view. say I start with 1234If I delete a row i end up with34The code below will count the number of rows and then add the numbers i require to the listview however they will start from the last row.134123
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim intIndex As Integer
I'm using VB08. I've populated a listbox with numbers and I want to add all those numbers together and display the result in a Label. I've heard about using parse but I don't understand exactly how it works.
This is the code that I have that i think should work.
Dim lblTotal As Decimal Dim sum As Double For Each decAdded As Decimal In Me.lstRunningTotal.Items sum += Double.Parse(decAdded) Next lblTotal = FormatCurrency(sum)
When I run it, nothing happens. My "For Each" statement I'm not sure if it's doing what I think it's doing. I can't believe I spent 6 hours banging my head against the wall but I finally got it figured out.
This is my revised code:
Dim sum As Decimal For Each decAdded As Decimal In Me.lstRunningTotal.Items sum += Decimal.Parse(decAdded) Next lbl_Total.Text = sum
I have 20 textboxes. each contains a particular number . I want the textbox1 to textboxN to have the numbers in the descending order. If any of the textbox has a zero value then I want to leave that textbox as it is. A sample code in vb.net needed.
