Removing Part Of Text?
Aug 17, 2009
I have 20 checkboxes (I don't use checkboxlist because if user click on checkbox then new window appear) in one form. I want to do that when user select few of those checkboxes they will appear in new textbox or label in new form. But I have a problem, when user uncheck checkbox the data is not removed from textbox or label. How can I do, that only text of that unchecked checkbox is removed from textbox or label.I tried with for each look up but i don't know how to do that either, so I am doing that with IFs for every checkbox.

program makes strings from webbrowser documenttext.For example
String1 = "<span class""long-title"" title"" Informations here"
Im trying to remove all text before "Informations here" this is what i currently have.
dim mychar as char () = {"<"c, "s"c, "p"c, "a"c, '....thatandlike20moretill.... "e"c, """"c}
string1 = string1.TrimStart(mychar)
(Note that each letter or symbol inbetween the quotations is a part of the string (span = "s" "p"...)Now this works. Not all the time though and its a pain in the .. having to do "letter"c, all the time.. (I got over 10 strings lol) Im wondering if theres a way easier method to remove part of string from the beginning, maybe like still a certen part of the length..

I have a file location as a string. How can i remove the path from the string and just use the file name? For example:c:filesfile.zip - is the stringhow can i just make it so it's file.zip?keep in mind that the location is found by using anpenfiledialog(), so it needs to be able to remove the location wherever the file is.

I can't get a zero into a text-box, what I'd like to achieve is this: if the textbox is zero, then I want it to remain as a blank, until I enter value to that field.Actually When I activate the field via some other control, then I Never wants to display "0" zero in Textbox Fields, before operation done. By default which comes from the multiplication operation (txtUnitsPrice.Text = d1 * d2) into the textbox field. I have three Text box fields, i.e. Unit_Price, Unit_on_Order, Units_Price.
Unit_Price=0 or some time it have default value, i.e. 25, which display ok, but not the below field.
Unit_on_Order=0
Units_Price=0

I am searching a Richtextbox for a certain string. I want to keep the 1st string & remove all the repeats of it (and the line above it). I have managed to use the code below to color the 1st instance as blue & the others as red. But when I debug my program never finishes the load (goes into a type of loop).

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 am trying to remove all whitespace from a text file and store each character into an array. Is there any way to combine all the lines together without leaving any whitespace? I tried the .replace method but it only removes whitespace for each line. It currently shows like that, but I want it to be 1 whole block of text without whitepace in every line:

What .Net functionality will allow a conversion from unicode to 7bit characters? For example, let's say that I want to convert "" to "eea". I thought I would find it in System.Text but it has been eluding me.

I am in the process of developing a VB.net helper application that will combine two text files into one, remove the extra blank lines, do some calculations and spit out a new and improved text file.
My question is: at the beginning of each file is a header row that starts with a "01". How does one go about removing all of the other "01" rows but leave the first header line?
So far, I have succeeded at removing all of the "01" lines, which isn't what I want but hey, I got it to work

I have been working on this for quite some time now. I have a listbox that loads the names from a .txt file. When the user selects names I need it to delete the items from the list. I have the code to remove it from the listbox, but when I reload the form it puts them back in because it's reading the file.

I know this has been asked like a million times, but I cannot seem to find a solution that works for me. I have a text file..and lets say its named Test.txt.I have like a list of stuff in the file and I have a Remove button. I also have a listbox that has the contents in the Test.txt file listed on the form_load. So basically to try to explain this better..what I want is to delete the line that is selected in the listbox when I click the remove button. Let me explain in an example.The Test.txt has the same contents as the Listbox..so say my list is like this:
Hi
How
Are
You
If I have Hi as my Listbox.SelectedItem then I would like to remove that line from the Test.txt. I tried to load the contents of the file in a TextBox too and I can search and find the text in the textbox and focus on it and highlight it but I cannot delete it from there too.

I am attempting to get my program to store its, in this case, a Url list in a text file. This should be relatively simple and so far it has been, writing to the document has been easy and it has all worked well, however, I have been trying to get my program to remove a url from this list too. To achieve this I have created a temporary text file, named 'FavouritesTemp.txt' and write the content of a listbox (with the target of the delete command removed from it) and then replace the old text document with the new one. But I keep getting an error from this - saying that a process is already accessing this file, even though I have just created it! I have attached a picture of my error and the code I am using underneath.
Code:
System.IO.File.Create(My.Settings.ProgramInfoStorePath & "FavouritesTemp.txt")
MsgBox("Created FavouritesTemp.txt")
Dim FavouritesWriter As New System.IO.StreamWriter(My.Settings.ProgramInfoStorePath & "FavouritesTemp.txt", True)
For Each Item In FavouritesListBox.Items

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

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))
