I am having trouble in finding duplicate numbers in an array.the first one is to create an array with duplicates and then display the number that has been duplicated and how many times it has been duplicated.
Here is my uncompleted code:
Dim arry(4) As Double
arry(0) = 4
arry(1) = 44

I've been assigned a homework assignment where I need to use LINQ to find certain numbers within an array. I've read through the book and some online tutorials, for some reason I just can't seem to understand it. I'm not asking anybody to do my homework for me... Just asking if anybody could explain it better, maybe in more detail?

how to use a Dim numbers() As Integer thats bout it here is my problem that iam facing :Use a one-dimensional array to solve the following problem: Read in 20 numbers, each of which is between 10 and 100, inclusive. As Each number is read, print it only if it is not a duplicate of a number already read. provide the "worst case" (in which all 20 numbers are different). use the smallest possible array to solve this problem.
View 5 RepliesI have a code that generates random code using a set of letters. One for a random pin and another for a random code. I can loop the generation of my codes depending on the input. When I try to generate 1 to 3 set of codes it works fine. but if it's 4 and above. I always get a duplicate set of random numbers. I don't what wrong. My code for generating my codes are in vb.net and be passed to a stored procedure for inventory.

So basically I'm making a BINGO game on vb 2008 and i have a "call number" button. The letter and numbers get added to a list box each time. But i do not want the same number to be called. Is there a way that the program can read the items in the list box and not generate (Randomly) the same value again to be displayed in the label.This is what i have:
Callnum = Int(75 * Rnd() + 1)
lstNumbersCalled.Items.Add(lblCallLetter.Text & " " & Callnum)
[code].....
label10 displays which is the highest number
label12 displays which is the lowest number
label14 displays which is the number that is duplicated
My codes don't run 100% correct.:'(
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Label6.Text = Val(TextBox1.Text)
Label7.Text = Val(TextBox2.Text)
Label8.Text = Val(TextBox3.Text)

Get Random value with no duplicate

I have been working on a pythagorean theorem calculator and am actually stuck on the final bit of code. What I am trying to do is check the values (integers) inside a listbox, remove duplicate number (both values), and input one of the values into a textbox.
Here is an example of what I am doing:
LISTBOX VALUES
2
2
3
[code]....
When the program runs, check listbox value #1 and listbox value #2, if listbox value #1 and #2 match (2 & 2), input that value (not both duplicates) into a variable, remove both of the duplicate values, continue checking the rest of the values, and finally multiply the leftover values. I am sure that sounds confusing. Here is what the final output will look like
LISTBOX VALUES
3

how to eliminate duplicate random numbers displayed in labels ( a column of 5 labels). This is for a BINGO game i am doing. I have tried a Do .. Loop until structure with a for next but i am not sure how to proceed:

i have wrote a loop to search for duplicate numbers within a column in a database which i have got fine but when i find a duplicate i would like to get the all of the row so if 33 was a duplicate i would like to get the following row.
33MarkWhitesideM12/07/1958Michaeluuu
I have tried to do this buy use something i saw on msnd's website:
Dim foundRow() As Data.DataRow = customerDS.Tables("Details").Select("HNCNO Like '33%'")
However if i change the line to notice the i beside the like
Dim foundRow() As Data.DataRow = customerDS.Tables("Details").Select("HNCNO Like 'i%'")
but i get Index was outside the bounds of the array. Ok i know that means that there is nothing in my array. What i would like is to find the duplicate row associated i. you will probably understand me better when you see the code.
Private Sub checkRowsForDups()
Dim customerDS As DataSet
Dim dupArray As New ArrayList

I am making a Bingo game. I have a button which keeps on calling numbers which are then added to a list box. How do i make it that the numbers called don't repeat (get displayed in the "number called" label). Is there a way to use items already added in the list box to eliminate duplicate numbers.

I've a question to ask about what kind of the vb.net command suitable to use apply to get the duplicate serial number in notepad?
Ifstrdata.Contains(txt_sn.Text)
Then
if strdata.contains(txt_sn.text)> 1 then --> is this command valid to find those record more than 1 in notepad?
msgbox.show("Duplicate entries was found")
I don't know enough about VB.Net (2008, Express Edition) yet, so I wanted to ask if there were a better way to find files with different names but the same contents, ie. duplicates.In the following code, I use GetFiles() to retrieve all the files in a given directory, and for each file, use MD5 to hash its contents, check if this value already lives in a dictionary: If yes, it's a duplicate and I'll delete it; If not, I add this filename/hashvalue into the dictionary for later:[code]Is this a good way to solve the issue of finding duplicates, or is there a better way I should know about?

View 4 RepliesI've come unstuck on a certain point. I am trying to find a way to compare two lists and output only lines which are unique. In other words, remove both occurrences of duplicate lines.I'm relatively inexperienced with VB.NET, but this is how far I have managed to come;
Code:
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

1) search the array to find duplicates and add them to a second array, then have a second pass to remove anything which matches the second array.
2) search the array for one duplicate and store it, then search the array again to remove the duplicates, and run that process until there are no more duplicates.
Then again, I could be going about this completely the wrong way. If that's the case, feel free to knock some sense into me.
I am adding line entries in a .ini file. The problem is, I am creating duplicate lines in the file, which I do not want to do. I searched this issue online, and the consensus is to use an array, loop through for duplicates and create a new file. However, being so new at this and teaching myself how to code no less, I am at a dead end. This is not a school project, it is something I am doing for work on my own time. I have all of my code done for the program except for this last step.

i'm trying to get my course done for this class. My question is find the even numbers from 6 through 16. The thing is i'm working with events. How should i do this? i did a lot of research and i did find some code that might work but i'm not sure how it works and understand it. I'm by no means advanced with vb.net i'm just trying to finish this course. What i did find was that i have to use MOD? I'm not even really sure how i can use that with an event? Any code would be awesome to getting me on the road to finish this assignment.
I took this code out of a program that had to find even numbers and it works great but the only downfall is that it starts from 1 and then whatever number you want it to stop at. I only need 6 through 16 .

An assignment in my computing class is to find if any numbers from a set of 5 add up to 15, if they do award a point. I cannot figure out how to find if multiple specific numbers can be made from adding up a random set of 5 numbers. Are they any algorithms specific to this? Also it has to be written in visual basic.

Say for instance, I gave you the numbers
1, 2, 3, 4, 4, 6, 9, 1, 3, 4, 5, 5, 2, 4, 7, 9, 1, 5, 3, 6, 6, 8, 1, 1, 4, 7, 7, 8, 2, 4, 2, 1, 9, 1, 0, 1, 6, 3, 2, 1, 8, 8, 9, 8, 1, 5, 3, 2, 3, 4, 7, 9, 0, 1, 2, 4, 7, 4, 3, 9, 7, 2, 0, 1, 6, 3, 8, 1, 2, 4
What number appears more than any other number?This is very important to me, ...I need to find the MODE, of those group of numbers, ...the way that I did it before, I would make 10 TextBoxes, and have another text box to enter the number, and when the number gets entered it would increment the value of which ever textbox the number was in the main textbox, so if I entered a 1 into the main textbox, then the zero in textbox (1), would be incremented to 1, and if another 1 was enered and the button was clicked, the 1 in the Textbox for 1, would be incremented to 2, because 1 has a popularity of 2 now and has apeared 2 times..
Here's some code, to show what I've come up with by myself.
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
ONE.Text = ONE.Text + 1
End If
