I have the following code that replaces an item in a richtextbox with a new one. Reg-replace works fine but only when the pattern matches only one value. When there are two similar values in the richtextbox it matches them both. How can I replace based on specific lines?

Here's my problem i am trying to extract data from a forum
Now what i want is to remove a specific word from only a specific line
So here's a example
[quote=randombla13] I am the king of the world bla bla
[img]http//google.com/img.jpg[img]
[quote]This line should not be removed[quote]
[quote]
Now as you can see these are the codes you may have seen in many forums
Now want i want .Net to do is filter the the content in a textbox
And remove only the lines marked with red "[quote=randombla13]" from the first line
And the Extra "[quote]" from the end line
As you can see in the example the content has two "Quotes" so i jest want to remove only one from the first line and last line of the content
And note "[quote=randombla13]" the length after the = is Unknown it maybe of 6 characters or less or more
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.
I am new to programming, so I am looking for somewhere to start with this project.What My project needs to do, is that the user inserts data consisting of multiple lines (up to thousands of lines) Into a text box of any type.When a button is clicked on it goes through the lines and alters lines based on what it starts with.
[Code]...
Clicking the button would cause every line with DDE at the beginning to be deleted, while leaving everything else intact.I'm not just looking for handouts, I do want to learn. I just to know what to look at to do this.
I have a RichTextBox.
I want to input an integer and the RichTextBox to go to that line and delete all lines above it.
For example, if I have 100 lines in the RTB, and I specify "25" as the integer, I want lines 1-25 deleted and for the RTB to keep 26-100.
What I would like to be able to do is to take data from textbox1, textbox2, and textbox3 and modify the "Y" variables in lines 5, 14, and 15 by the value of textbox1. The "X" variable in line 5 needs to stay constant while the one in lines 14 and 15 change to the input of textbox2. Textbox3 needs to modify the "F" variable in lines 3 and 14. Then the whole text needs to be written out to notepad

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

I have 2 text files that are formatted in standard XML One of them contains some lines that need to be copied to the other. What i am trying to do is search through the first file until i see the string "<Segment" then copy all lines into a rich text box up until the string "<segment/>" I Then want to look through the other file until i find the string "<Jointfree/>" then copy the contents of the rich text box to underneath the Jointfree String I Also need to search the second file until i find the string "<Markers/>" and then paste some text into the line above the markers tag.

View 4 RepliesI'm using this code to load a text file into list box.
r = New IO.StreamReader(str)
While (r.Peek() > -1)
ListBox1.Items.Add(r.ReadLine)
End While
r.Close()
But it loads the whole file into list box. I only want to load those lines of text that contain following number: 2008. It doesn't matter if the "2008" is at the beginning, middle or the end of a line.
I'm making a button to delete lines not containing specific text.
For example, if the text is "test". I want to remove all lines not containing "test" in it.
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?

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

I am creating a simple researcher application to access and store data. As of today it workes by entering a number into a text field and hit enter/button. The result then shows up in a non-menu webbrowser window. What i would like it to do was to exclude the web browser window, and instead show in a popup window inside the application. 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.

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.
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:

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?

I am trying to read from a file that was created with a stream writer the names line from the text file that contains data for name, phone number, pager number, cell number, voice mail, and email.What I need to do is read and load the names from the file into a list box, and then from the list box be able to choose each name and have the information (phone, pager, cell, etc.) show up in text boxes that goes with the specific name.
View 4 RepliesI have asked questions about this before but my program has came to cross roads where I require more flexibility in my security procedures.At the moment I generate a specific key based on certain details about the system, and I hash this data to file, which ensures it will only run on this system.
However it has now got to the point where I have a need for providing keys which will carry settings for the program within the key. So that if a customer wants an update its the matter of sending an updated key, which will allow certain areas of the program to be unlocked/locked.Obviously I can no longer use the hash, as it can't be decrypted. I am looking to use key encryption system, which will allow to encrypt data within a license key. But obviously it brings the problem of where to store Crypt & decrypt key within the program.

I have the need to disable multiple controls based on specific circumstances.[code]Thing is, this doesn't work for ToolStrip items. Is there a way to do this without checking the type of each control passed to the function?
View 7 RepliesI need to determine the ranking of the List items specified by one specific property of the items.
I have the following Class:
Public Class LevelA
Property items as New List(Of LevelB)
Public Class LevelB
Property factor as Double
ReadOnly Property rank as Integer
End Class
End Class
For example, let's say I have three items in the List. I have set the factor property for the first item as 5.50, the second item as 6.60 and the third item as 3.30.Now I should be able to get the rank property of each item (the highest value should be ranked as 1). Here the first item in the list should have the rank as 2, the second item as 1 and the third item as 3.
What kind of procedure is needed for the "ReadOnly Property rank as Integer" for returning such values? It should somehow be able to access the list in the parent class probably?
