Removing Duplicate Rows In A Textfile Then Add To Datatable?

Aug 16, 2010

I am reading a textfile and extracting information from each line. For example string1 and string2. I am then writing these string to a datatable.

However, sometimes there will be repeats in string1 and string2.

If there are repeated lines I would like to be able to delete the repeating line and add a counter to find the total number of repeating lines.

so if a string repeates 3 times I would like there to be a column with a 3 displayed next to the line in my datatable.

Count Duplicate Entries In TextBoxes?

Oct 2, 2010

I have 50 Texboxes.

I need to count the number of duplicate entries, and provide a summary (count) for each product code. This makes it easier when the order needs to be placed, and the user don't have to count each value manually.

I have tried looping through all 50 boxes to no avail. This seemed easy, but, clearly I am to thick to think of a solution.

Remove Line From Textfile?

Mar 11, 2010

I am having trouble removing a line from a text file. When I click on the button in order to remove the line it gives me an error that access to the file is not possible. Now I assume that the file is in use during me wanting to change it and therefore cant save it while it is loaded in ht application. I have tried a few things but cant seem to get it to work.Essentially what it does is that I have another dialog that a used can add data, the data is then written to the file FilingLocations.txt and then it saves it and loads it again. But once the line is no longer needed I would like to have the option to remove the line agaise.

Here is the code:
Private Sub cmdRemoveLocation_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdRemoveLocation.Click

VS 2010 Remove Lines From Textfile?

Jun 19, 2012

I have two text files and each text file has various columns (each column is separated by a tab " "), now some of the fields in column1 text file2 match the fields in column1 text file1. What I'm trying to achieve is to remove every row in text file 1 where the field in column1 matches the field in column 1 textfile 2 - is this possible?I have used some basic coding in the past to remove certain lines, but nothing as complex as this.

Dim linesList As New List(Of String)(File.ReadAllLines("Path"))
linesList.RemoveAt(1)
File.WriteAllLines("Path", linesList.ToArray())

Array - Remove Duplicate And Original?

Apr 11, 2010

I'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, 2012

I'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"
