Array - Remove Duplicate And Original?
Apr 11, 2010I'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
Dim LinksList1, LinksList2 As String
LinksList1 = Replace(RichTextBox1.Text, "#vch", "") : LinksList2 = Replace(RichTextBox2.Text, "#vch", "")
[code]....
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.

C# - Remove Duplicate Char On String (more Than 3 Occurrences) Using Regex?
Jan 13, 2012I'm sorry if it's a duplicate of some question but this is specific on Vb.Net Regex function.
I need to remove any occurrence of 3 or more duplicate characters on a given string. For example:
Dim strTmp As String = "111111.......222222 and 33"
Dim output As String = Regex.Replace(strTmp, "????", "")
Debug.Print(output)
The "????" part I guess should be the Regex expression, which I must assume I know almost nothing about.
I don't know if that's the correct syntax. But I need the output to come as:
"1.2 and 33"

Doesn't The Union Function In LINQ Remove Duplicate Entries?
Aug 9, 2009I'm using VB .NET and I know that Union normally works ByRef but in VB, Strings are generally processed as if they were primitive datatypes.Consequently, here's the problem:
Sub Main()
Dim firstFile, secondFile As String(), resultingFile As New StringBuilder
firstFile = My.Computer.FileSystem.ReadAllText(My.Computer.FileSystem.SpecialDirectories.Desktop & "1.txt").Split(vbNewLine)

Edit Item Or Subitem Values Of A Selected Listview Item?
May 19, 2009Ok, so I have a listview on one form, and when a button is pressed it opens up a new form with the contents of the selected listview item and it's subitems in a series of textboxes. The user can then change the data in the textboxes and either press save to make the changes or cancel to close the window. What command would I use to change the selected listview item and subitems to whatever is in the boxes?
this is the code that populates the boxes:
Private Sub Form_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim appeditcontents As String = main.passlist.SelectedItems(0).ToString

Detecting And Deleting Duplicate Entry's In A ListView?
Jun 14, 2008I need help on improving the performance of a program I wrote some time back. This is the main performance issue of the program below. Basically I need to look through some data that is displayed to a user in a list view and determine if the data is a duplicate of any other data in the list. If it is I need to delete the duplicate before my program continues.The below code does the job just fine, however the list view of data has approximately 30,000 rows of data. Hence looping this list 30,000 to the power 30,000 times makes the program very slow. Note subItem(4) in the data is the "unique" identifier that I later discovered was not so unique....
This was a work around function implemented in the code back when I wrote it (not meant to be permanent). I know that listView is not Ideal to store this much data.how to store the data in a more efficient manner or improve the performance of the Search and Delete [code].....
Removing Duplicate Items From A Multicolumn Listview

However, I am now in a tough spot because I need to find and remove duplicates from a multicolumn list view. I tried using LINQ but it says that the listview object is not "queryable". Is there a way for me to find and remove duplicates using only one column of the listview? [code]The code now runs fine when I call it. But it does not remove the duplicates:
