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

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?

VS 2008 Removing Line Of Text Containing String?

Nov 30, 2009

I'm trying to build an app that would search a text file for a string entered by the user, and delete the line of text containing that string. Here's the code I have. The code works, but since I'm relatively new to VB and programming as a whole, I was wondering if there's a better method out there. he strFilePath is handled by the openfilediaglog

Dim strSearch As String = Replace(MaskedTextBox1.Text, "-", "")
Dim strLine As String = Nothing

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.

VB 2008 - How To Display 2 Text Lines In A Button

Simple question I couldn't find in the book or online. I have a Button which needs to have permanent text set to 'Calculate' and 'Section' on separate lines. The 'Multiline' option I have seen mentioned does not appear in my properties. I can't 'show the code' as I think it is a properties setting.

Apr 26, 2012

I am COMPLETELY new to Visual Basic except for a high school Computer Programming class and I'm attempting to make a text-based game via VB2008. There is a tough problem I'm having. I followed a few YouTube tutorials and managed to create something where you can press a button and have a window open where you search for a text file and have it's file path appear in a text box. My problem now is that I want certain lines of this text file to change the text of certain Labels on a different form. I don't know how to do this though?

I have a text file that I'm reading into a listbox. I want to skip a line if it's blank. The following code works if I leave out the check for the line being blank. It puts the file in the listbox with no errors. However, when I include the If statement that checks for the line being blank, I get an ArgumentNullException in the Items.Add line when It gets to the end of the file.

how to count the lines in textbox1.text (with multiplelines). I don't need to count each character. I only need to count each line from top to bottom in textbox1.text (multiplelines) and I will use Label1 to display the numbers.

2-tommyperrry
3-marktoms
4-Jonessmith
5-paulwhite

Obviously this is 5 lines and that's what I need to count.

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.

Jul 22, 2011

I can't get a zero into a text-box, what I'd like to achieve is this: if the textbox is zero, then I want it to remain as a blank, until I enter value to that field.Actually When I activate the field via some other control, then I Never wants to display "0" zero in Textbox Fields, before operation done. By default which comes from the multiplication operation (txtUnitsPrice.Text = d1 * d2) into the textbox field. I have three Text box fields, i.e. Unit_Price, Unit_on_Order, Units_Price.

Unit_Price=0 or some time it have default value, i.e. 25, which display ok, but not the below field.
Unit_on_Order=0
Units_Price=0
