Removing Lines From A Text File?

May 29, 2012

I am in the process of developing a VB.net helper application that will combine two text files into one, remove the extra blank lines, do some calculations and spit out a new and improved text file.

My question is: at the beginning of each file is a header row that starts with a "01". How does one go about removing all of the other "01" rows but leave the first header line?

So far, I have succeeded at removing all of the "01" lines, which isn't what I want but hey, I got it to work

Reading And Writing Lines To And From .text File?

Mar 25, 2012

I'm writing a program where there are text boxes and the user can enter info and append them to a text file as well as read from the text file and view the various entries in it. The problems I'm running into are that I have a button that opens an open file dialog box allowing you to select the file, and I want to get it to open the first entry of that file in the correct text boxes. the code so far looks like this

code:

I used to have this bit of code in there but there was a conflict with the .txt file being used more than once at the same time while it was in there.

code:

Im also having trouble writing to the file and I'm not sure why. I have an "Append" button that has this code in it

code:

and it comes up with the issue "object reference not set to to an object instance".

VS 2010 - Writing Different Lines To Text File

Jan 30, 2012

I want to create a little program with textboxes in it, that writes the contents of these textboxes to a file. It also needs to write some predefined lines to the files, even on the same line as where the contents of the textbox is.

Heres an example:
The file should look like this when you open it in notepad:
^1::
Send t Text from TextBox {Enter}

First I think I would need to do this:
Dim ioFile As New StreamWriter("scripting.ahk")
ioFile.WriteLine("^1::")
If I do the above it works.. But how can I write another line where the "Send t" and "{Enter}" gets written automaticly before and after the contents from the Textbox?

Reading/Writing Specific Lines Of A Text File?

Apr 21, 2009

I'm trying to create a program that stores a users stats for their character (for something like an RPG). I know how to write more than one line in a text file, but I want to learn how to read and write text on specific lines of my file. I know that you can just read each new line individually in order using a StreamReader, such as

username.text = readLine.ReadLine()
userage.text = readline.ReadLine()

[Code]....

This is good for just displaying the stats and changing them from a constant interface, but I'm afraid that eventually I'll need to read/write specific lines, like reading the fourth line which might specify magic level, or writing a new money amount.

Get A Bunch Of Lines From A Text File (they Will Be Filenames Eventually) Which Are Split By New Lines And Puts Each One Into An Array?

Jun 22, 2010

I have written a simple script to get a bunch of lines from a text file (they will be filenames eventually) which are split by new lines and puts each one into an array..

Dim ary() As String
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If My.Computer.FileSystem.FileExists("C:MenuFiles.txt") Then

[code]....

The only thing I can do for now is either use the substring function to remove the first character from all array values after 0 but I don't like that because it's messy and what if the split "works" as I want it to one one of the lines and knocks of the first character when I don't want it to.

Read Lines From Text File 1 And Delete Those Lines From Text File 2?

Sep 15, 2009

I have a text file containing lines of data (File 1). I need to delete all the lines in another text file (File 2), which are found in file 1.So I could read file 2 line by line. And then once the line has been read, read file 1 line by line to search for a match. But that's going to be painfully slow.Or I could read file 2 into memory. And then read file 1 line by line and REPLACE the lines in file 2 with nothing, therefore deleting them. File 2 could be 100 mb, so I'm not sure about reading it all into memory.

Add Trailing Text After Checkbox For A Datagridview CheckBoxColumn?

Oct 2, 2011

Is is it possible to add trailing text after the checkbox for a Datagridview CheckBoxColumn?

The situation is like this. Say the DataGridView shows name of employees from datatable. The user can select employees from the displayed list in the DGV. For the selection, I inserted a checkboxcolumn into the datagrid. Everything OK.

But just want to know whether it is possible to merge the two column into 1, so that the check box precedes the name of the employee in the same cell rather than in a different column.

Removing 1 Line From A Text File?

Dec 3, 2010

I'm really stuck on something, which, is probably easy, but I've blown hours trying to figure this out.I need to be able to remove 1 line from a textfile. I will always know exactly what line it is, as, it's the same "string" as a variable. So if my variable is called "removeThis" then I need to be able to Read through the textfile, find the line that is equal to the removeThis string variable, and then rewrite the whole textfile.

Removing Textline From Text File?

May 5, 2009

I know this has been asked like a million times, but I cannot seem to find a solution that works for me. I have a text file..and lets say its named Test.txt.I have like a list of stuff in the file and I have a Remove button. I also have a listbox that has the contents in the Test.txt file listed on the form_load. So basically to try to explain this better..what I want is to delete the line that is selected in the listbox when I click the remove button. Let me explain in an example.The Test.txt has the same contents as the Listbox..so say my list is like this:

Hi
How
Are
You

If I have Hi as my Listbox.SelectedItem then I would like to remove that line from the Test.txt. I tried to load the contents of the file in a TextBox too and I can search and find the text in the textbox and focus on it and highlight it but I cannot delete it from there too.

Removing URL From List In Text File

Nov 12, 2009

I am attempting to get my program to store its, in this case, a Url list in a text file. This should be relatively simple and so far it has been, writing to the document has been easy and it has all worked well, however, I have been trying to get my program to remove a url from this list too. To achieve this I have created a temporary text file, named 'FavouritesTemp.txt' and write the content of a listbox (with the target of the delete command removed from it) and then replace the old text document with the new one. But I keep getting an error from this - saying that a process is already accessing this file, even though I have just created it! I have attached a picture of my error and the code I am using underneath.

Code:
System.IO.File.Create(My.Settings.ProgramInfoStorePath & "FavouritesTemp.txt")
MsgBox("Created FavouritesTemp.txt")
Dim FavouritesWriter As New System.IO.StreamWriter(My.Settings.ProgramInfoStorePath & "FavouritesTemp.txt", True)

[2005] Removing A Line Of Text From A .txt File?

Feb 23, 2007

I am writing an app that writes notes, inserted by the user, to a txt file. The app saves that notes to a txt file, and when opening it reads the file and shows the already inserted notes. However, I want the user to be able to delete some of those notes...but I can't seem to do it...this is what I have:

VB
Dim file As New FileStream(data_path & "notes.txt", FileMode.Open)
Dim text As String = Nothing
Dim reader As New StreamReader(file)

It goes fine, but the text.Replace(value, "") line doesn't seem to work. I've also tried text.Remove(0) but it doesn't removes the line...it looks like it has no effect.

Removing Specific Lines Of A Multiline Textbox

Feb 26, 2010

What I am trying to do is remove lines of a multiline TextBox based on certain criteria, such as the number of characters or words. For example, if I paste a list of phrases into the TextBox, I want to remove all phrases that contain more than 25 characters. Once the phrases are removed, I then want to remove the empty lines that are left behind, but I have commented out the ".Replace(vbCrLf & vbCrLf, vbCrLf)" for the sake of making the results easier to follow (see screenshot from Excel below, which includes a blank cell wherever a phrase has been removed).

Here is my

Private Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click
Dim lines() As String = TextBox1.Text.Split(vbCrLf)

[Code]....

Why is it not "blanking" the entire line in ALL cases where the line contains more than 25 characters?

.net - Programmatically Removing Garbage Text From Excel File?

Nov 26, 2010

I have an Excel file that downloads automatically, but for some reason the binary XLS file contains some garbage HTML text at the end of it.

When opening the file in the Excel application, it shows a warning but proceeding will automatically remove the garbage HTML text.

However, I need to open the file programmatically. When doing so via

Dim wb As Workbook = Excel.Workbooks.Open(ExcelFileName)

It throws:

Exception from HRESULT: 0x800A03EC

a) Get Excel to perform a similar action as if I manually opened it and remove the garbage HTML automatically. NOTE: Tried setting the XlCorruptLoad.xlRepairFile parameter and it didn't work.

OR
b) Remove the garbage text from the XLS binary file (FileStream?) and resave it before attempting to open the file with the code mentioned above.

The garbage html always comes at the very end of the file and starts with

File I/O And Registry :: Deleting Lines In A Sequential Text File?

Mar 22, 2009

I know that Deleting a specific line in a sequential text file is impossible but instead copy the needed lines and not copying the unneeded ones to an output file .. killing the old one and renaming the new one with the same.. I can't make this step...

That is my record file

Code:
Input #1, CustomerName, CustomerHomeAddress, CustomerBussAddress, CustomerTel1, CustomerMob1, CustomerID, DateRent, CarRegPin

Code:
"Josek Sam","68 West Land Street","149 Union of States","4524563","45635463","JOSKSAM1",#2009-03-02#,"MILANCGLZ2008"
"Josef Malm","142 Unions Street","64 Hamersters Street","452504","42542054","JOSFMALM2",#2009-03-06#,"MILANCGLZ2008"
"Dave Green","131 Oxford Street","96 BlueBane Route","452542452","43254345","DAVGRN3",#2009-03-07#,"MILANCGLZ2008"

I made a form that when you put your CustomerID in Text3 Box.. it access the records and make some calculations. now.. The customer will return the car.. Then his data should be deleted.. I want to know how to make that when I enter the CustomerID and press on the Command button .. It copies the other lines to a new output folder and doesn't copy these ... So it appears to be deleted using this way..
