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 have a comma delimited text file, like this;

my program can add new lines and select url's but I can't get the remove button working, I read that (maybe) I have to read all lines and write a new file.

Sort An Array And Remove Duplicates?

Sep 8, 2009

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"

Remove Character From A Text File And Prevent Crash W/ No Text File?

Apr 7, 2011

All I would like to do is remove one character from the line of the text file that I am reading, which is the first character and also prevent the program from crashing if no text file is present.Here is the code. Can anyone notice where I am going wrong? I thought the "if" statement would cover the crash but it didn't. Clueless, but sort of have an idea on the character removal.

Dim fileReader As System.IO.StreamReader
Dim lineRead As String

.net - Edit Text File And Remove Value?

Jun 21, 2012

I have two text files. The fields in each text file are separated by a space (" "). Some of the fields in column 1 of file 1 match the fields in column 1 of file 2. However the third column in file 2 is a numeric field. What I wish to do is check every field in file1 against the field in file 2, and if the number is 1 then remove the row from file 2, if the number is > 1, then subtract one from it.

I have the following coding so far.

Dim lines1 As New List(Of String)(IO.File.ReadAllLines("File1"))
Dim lines2 As New List(Of String)(IO.File.ReadAllLines("File2"))
Dim values As New Dictionary(Of String, Integer)()
