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
Dim strAllText As String = Nothing
[code].....

I have not had much time to go threw my code properly as this is some urgency. I need to remove line 1 from a textfile if it contains a string but its not working.I have 500 files and not going to do this manually.
Code:
Private Sub btnRemove_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRemove.Click
If String.IsNullOrEmpty(txtDirectory.Text) Then
OpenFolderDialogDirectory()
[code]....
I also feel the function is very pointless sime i am opening the file twice.

I have strMyString that contains about 5000 lines of data. There are some lines of data that need removing if they contain a certain string, such as "http", "www.", ".com", "cat", "fish", etc. The whole line needs removing. Each line is separated by a vbNewLine or similar.
How can I do that? Does it need pasting into a rich textbox first before processing?

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.

I'm trying to have a program remove lines from a text file if they start with a certain string. I haven't had much luck with this over the past couple of days so I thought I'd try and get some advice.
This is the code that I've tried most recently, and makes some sense to me, but gives a "A first chance exception of type 'System.ArgumentOutOfRangeException' occurred in mscorlib.dll" error:
Dim SourcePath As String = "C: est.txt"
Dim fileLines As List(Of String)
fileLines = New List(Of String)(File.ReadAllLines(SourcePath))

I am reading a list of IP's from a text file. After every procedure, the first IP (the first line) needs to be removed, and the new first IP will be read at the beginning of the next procedure. Basically, I just need to know how to get rid of the first line of a text file completely. For example, I'd like to go from this:
1.1.1.1:80
2.2.2.2:80
3.3.3.3:80

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)
[Code]....
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.

I'm trying to remove a line from a text file that begins with a set value.
The idea would be to paste values into a Windows form, which then finds each line that begins with that value (a 5 digit number) and removes those lines from the file, and then removes the gaps.

Basically what I'm trying to do is read a text file line by line. After each line is read, it will put each line into a separate text box. I've been trying to do this for a while and so far I haven't been able to. I tried using a for loop, but that just put all my lines in to one textbox.

I have an arraylist of strings, one of them looks like this:It's wet out here and [player id=3686163]Ripper[/player] knows it. That ball was like a bar of soap in a prison - nobody wanted to pick it up. Knock-on.
I need to remove the square brackets and the contents of them, to give:It's wet out here and Ripper knows it. That ball was like a bar of soap in a prison - nobody wanted to pick it up. Knock-on.
The contents of the square brackets are likely to change from string to string, and in some case I may have more that one player in that string.

Ok, I saw this code on the net
Dim sFileName As String
Dim srFileReader As System.IO.StreamReader
Dim sInputLine As String
sFileName = "D:UsersArbenDesktopSerieA.txt"
srFileReader = System.IO.File.OpenText(sFileName)
[Code]...
under the code I pasted at the top, but I get the text on line1 in all labels, like all labels become 1, while the text should be 1, 2, 3 and so on. So anyone can help me do that, each label gets the value of the next line in the txt file

I am still very new to VB. I am having trouble working out how to remove lines within a rich text box, based on the next new entry into the rich text box.
For example:
rtbClient (the rich text box) already has the lines:
long cat is long
he really is
long cat is long
Now, if the next NEW entry into the rich text box is "long cat is long", then the new "long cat is long" string would be ignored because the line previous (and only the previous line and not all lines that already exist) is exactly the same. Note, I know of the Me.rtbclient.Lines = Me.rtbclient.Lines.Distinct.ToArray code, iv tried playing around with it with no luck.

I've been trying to fix this problem for days, but I haven't been able to successfully apply any of the code that I've found to my project the way it is right now. Maybe I'll need to change the way it reads the file altogether.
Anyway, I'm trying to read through a text file line by line, reading each line into its own string.
