I have a semicolon delimited string (e.g. an EMail Address List returned from a database or a textbox). How do I separate the string into an array, sort, and remove duplicates? The code below works to separate the string and sort the results, but doesn't remove the duplicates. I could probably then loop through the array and copy to a new array to eliminate the duplicates, but there must be a better way to do this using the VB.Net Array, String, and Collections handling classes.
Dim s As
String =
"Test; Test8;Test1;Test2;Test3; Test8;Test4;Test5; Test6"
Sub Sort() ReDim RollsCC(NumOfPlayers - 1) For N As Integer = 0 To (NumOfPlayers - 1)[code]....
Here I am creating a temp single dimensional array, merging my 2d array into it, and then attempting to sort it by Rolls(N,1), which is a integer 1-6, Everything seems to be working right with the exception of this.
RollsCC.Sort(RollsCC, 0, 1)
How would one specify a numeral sort based on the first character in the string? im aware that I am switching Rolls(n,1) and Rolls(n,0) information during the sort.
i use csv file to populate my dgv. now i wanna eliminate duplicates from my dgv. i knew it could be done using unique datatable. but i wanna eliminate it from dgv not from the dataset or datatable.to understand it in better way- i wanna check column1 if the vales in column 1 are repeated then the entire row must be deleted i.e the duplicate row must be deleted( if column 1 has 2 duplicate values then 1 row must be deleted)
I want to remove duplicate values from a string using VB.NET. If values = "3,40,15,109,15" then I need the end result to be "3,40,15,109". I'm using the code below but receiving the error message 'Value of type 'String' cannot be converted to '1-dimensional array of String' and I'm not sure how to proceed.
Dim values As String values = lblIDList.Text 'Remove duplicates values = RemoveDuplicates(values)
[code]....
Value of type 'String' cannot be converted to '1-dimensional array of String'.
I have the following coding in place which basically edits my text file, however with the information that is shown in the text file I want to remove all duplicates, is this possible?
Dim path As String = "c: est1.txt" Dim sb As New StringBuilder Dim sr As New StreamReader(path)
Depending on the data being used, I can have up 10,000 items in each of the 2 ListBoxs. I need to find and remove any Duplicates between the 2.I am currently using the method of select and Item from Listbox1 and search in Listbox2. If I find a match, then remove both items. This goes back and forth until all the duplicates have been removed. This take some time.Currently have the code in Old VB6 and VB2008 Express.
I have my code it is able to read a text file and do checks each line if there are 7W and 5L in that particular line, if no matches it will remove that line... 1 problem i face now is that, there are duplicates in my textfile..Im not sure how am i going to remove the duplicate in the text file. I want to know if there is a way to integrate an additional function inside my code to check if that particular line is a duplicate so i can accomplish 2 tasks at 1 time... Since there are about close to 1million records in my text file.
I know how to remove duplicates in an array (have a simple function for that) but now I was trying to do the same in a matches collection and I can't get anything to work somehow.
In this case the matches collection has a few duplicates that I want to remove.
Dim matches As MatchCollection matches = Regex.Matches(sExtractedText, "word=""[dw]{8,30}""") For Each match As Match In matches
the question states im looking to remove duplicates from a textbox in the sense that i have two textboxes like this

My goal here is to remove item 1 and 3 from the first listbox if it exists on the 2nd listbox, ive searched for 30 minutes to no avail, found a similar question on how to do it in vb but still didnt give me a idea on how to do it relating to vb.net also this is more then one instance,
Ok, I found some code online on how to do this, but they only compare the Listview.item.text, and they don't care what is in the entire ListViewItem. Is there any code to remove duplicates in a ListView that checks to see if all the subitems are the same as well and THEN removes the entry? [Code]
I started programming Visual Basic .NET a few weeks ago. I wanted to make a tool to remove duplicate lines from a listbox. I have the following
Dim strItems As New List(Of String) 'Make a list with originals Dim strDup As New List(Of String) 'This list contains the duplicated lines
For i As Integer = 0 To ListBox1.Items.Count - 1
LabelChecking.Text = "Checking for duplicates: " & i & "/" & ListBox1.Items.Count - 1 Application.DoEvents() If strItems.Contains(ListBox1.Items(i).ToString) Then
I'm trying to make a snippet that will remove duplicate lines from text files. However, I seem to be mixing my for loops up.. does anyone know a simple way that I could do this?
I am using the Array type .Sort function to sort my array.By default it places the result Array into Ascending order Least to Greatest How do I change that to Descending order Greatest to Least?and How do I change it to Closest to logic? or does that not exist?Assume there is an Array of Numbers 0,13,21,-2,4,5,1.34 and I want them to sort closest to 0 or some other arbitray value; the Output should look similar to:
I have an multi dimed array of stock sizes, material type and count. The array could have duplicate arrays. In the end I need an array that is condensed with no duplicate and the count field is how many there were in the array. Example: Original array Material: STL TUBG Stock Size: 3" X 3" X 0.250" W/T X 254MM Material: STL TUBG Stock Size: 3" X 3" X 0.250" W/T X 254MM Material: STL TUBG Stock Size: 3" X 3" X 0.250" W/T X 254MM Material: STL TUBG Stock Size: 3" X 3" X 0.250" W/T X 254MM Material: STL TUBG Stock Size: 3" X 3" X 0.250" W/T X 102MM Material: STL TUBG Stock Size: 3" X 3" X 0.250" W/T X 102MM Material: HRS Stock Size: 1" X 4" X 175MM Material: HRS Stock Size: 1" X 4" X 175MM Material: HRS Stock Size: 1" X 4" X 175MM Material: HRS Stock Size: 1" X 4" X 175MM I need Material: STL TUBG Stock Size: 3" X 3" X 0.250" W/T X 254MM Count: 4 Material: STL TUBG Stock Size: 3" X 3" X 0.250" W/T X 102MM Count: 2 Material: HRS Stock Size: 1" X 4" X 175MM count: 4
How do I not return duplicate random numbers with Do Until loop?
Dim numbers(5) As Integer Dim subscript As Integer Dim searchSubscript As Integer Dim randomNum As Integer Dim randomGenerator As New Random Dim isFound As Boolean
I have a huge array, well Data Grid actually (unbound), but it can be populated into an array... 47 columns by 2000 rows. The data within is random, I need to check each row for duplicates...
essence is on the quickest method though as it will be called by the user. The data is populated by column, so I can not check for duplicates during population.
e.g.
DataFR1, DataBF2, DataJU3....... DataXN47 DataHY1, DataBF2, DataJU3....... DataXN47 DataFR1, DataBF2, DataJU3....... DataXN47 << This is a duplicate >>
I can perform the 'compare' but i'm struggling with the speed.. because row 2000 could be the same as row 1 I can only get my head around a solution that would be very slow
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'm trying to sort an array based on a structure but whenever I do this, it basically erases all the data in the entire array.I have verified that the array is populated correctly, it is when using array.sort that everything returns blank.
