Display Specific Lines From A .rtf?
Oct 2, 2011At 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.

Removing Specific Lines Of A Multiline Textbox
Feb 26, 2010What 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?

Value To Retrieve With Specific XML Element Path
Feb 16, 2010I have only recently discovered the world of fetching online data using XML functions in VB.NET and it has been working well so far. Unfortunately I have hit a hurdle and am unsure as to how I should proceed.

Now I have an XML which looks like this (apostrophes to represent indentation):

Find And Replace Specific Lines In A Text File
Aug 4, 2011I 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

This should be rather easy, here's what i think might be a problem. I want only to show specific lines from the webpage, not the whole page.

Reading/Writing Specific Lines Of A Text File?
Apr 21, 2009I'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, 2012I'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?
