VS 2010 Removing Line From Either String Or Textbox

Aug 3, 2011

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?

Removing Last Line In RTB If Next One Is Same

Aug 26, 2010

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.

Removing 1 Line From A Text File?

Dec 3, 2010

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.

PictureBox Label Removing Underneath Line

Oct 12, 2010

Any way to remove this problem I have in VB2010. I've done a picture box, where you can draw lines by clicking with your mouse. There is a label running along with the mouse pointer, but every time the cursor moves over the line, the label removes the line under it. I've tried setting transparent background to the label.

VS 2008 Removing Line Of Text Containing String?

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

VS 2010 Removing Line From Text File?

Aug 20, 2011

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))

VS 2010 Removing The First Line Of A Text File?

Sep 4, 2010

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

[2005] Removing A Line Of Text From A .txt File?

Feb 23, 2007

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.

VS 2010 Removing A Line Form A Text File?

Feb 8, 2012

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.

Parsing Multi-line Clipboard Text Into A Single Line And Pasting Into A Textbox?

Feb 7, 2011

a user copies multiple lines of text (say, from an email) into the clipboard. Based on my observations, when one tries to paste the text into a single-line textbox, only the first line is actually pasted in. (I am aware that the "obvious" solution would be to set the Multiline property to True, but there are reasons I am looking to avoid this and to put multi-line data into a single line.)

In the TextChanged event handler, I wrote code that parses the clipboard data to successfully convert it to a single-line, comma-delimited format.

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?
