Operating With Specific File Lines?

Apr 15, 2012

I'm working on a program which should edit a text file by adding/deleting some specific lines.By default this text file doesn't have these specific lines, so the program will add them.But I also want it to replace them if they're already in the text file.Basically this is my idea:- Read the text file- Search the specific lines- If they exist then replace them

Find And Replace Specific Lines In A Text File

Aug 4, 2011

I have a program that will read a text file and put information from the text file into multiple text boxes. What I am trying to do now is be able to change the values in the textboxes and be able to write the specifc changes back to the text file. One way I though of doing that was using a while loop and copy the lines of the text file to another text file, then when it finds the line that has the specific change from the text box, make the change and continue writing the line until it reaches the end of the file. Then I was going to copy the file and overwrite the original, escientally making the change to the new file. Right now it will make the new file but will just make a blank text file. I think the problem is in the while loop statement but I am not sure. Here is the code below:

Code:
Private Sub submitButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles submitButton.Click
Dim trackname As String

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.

VS 2010 Editing Text File Specific Lines?

Feb 13, 2012

I'm new here and I'm trying to make a little program with Visual Basic (2010 Express Edition).The purpose of this program is:

1) Load the text file lines and split them into a constant and a value

2) Edit the text file lines values

The content of the text file is like this:

[Code]...

This basically split every lines in two parts: the constant ("Name", "Surname", "Age", "Hair") and the values ("Mario", "Rossi", "50", "Black").Now about the second point, I've added a Button1 which should take the Textbox1/2.Text and the Combobox1 selected item and replace the values(aka separator(1)) in the text file. The problem is I don't have any idea at the moment how to do it. What method should I use?

Display Specific Lines From A .rtf?

Oct 2, 2011

At the moment I'm using:

For Each book In books
result.Add(File.ReadAllText(book).Substring(0, 500))
Next
Return result

to display the first 500 characters of an rtf file I'm drawing from in earlier code, but I'm now wanting to specify line - for example lines 4 - 20.I can't find any way to get this to work as when I change the above code to:

For Each book In books
result.Add(File.ReadLines(book).Substring(4, 24))
Next
Return result

I get massive issues stating "Substring is not a member of 'System.Collections.Generic.IEnumberable(Of String)" I feel like I'm literally 1 line of code away from this being fixed but cannot get my head around it.

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.

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?
