Reading TXT Files From ListBox And Removing Set Of Words
Feb 20, 2011
Currently, my application will send the contents of a directory into a list box.
Dim folderDlg As New FolderBrowserDialog
folderDlg.ShowNewFolderButton = True
If (folderDlg.ShowDialog() = DialogResult.OK) Then
ListBox1.Text = folderDlg.SelectedPath
Dim di As New IO.DirectoryInfo(folderDlg.SelectedPath)
[Code] .....
For now, all that is inside the directory is a text file. I would like my program to read the contents of the text file and remove a set of common words, but I don't really know how to move forward here. Would it be best to create a class that holds a set of words that I would like to remove, then loop through the text file, remove any words that match those inside my class and then write what's left to a new .txt file?

I have a situation where a user can enter just about anything they want into a text box.Whatever they enter in the box, I need to split the string into an array of strings where each item is one word. For example, if the user enters All State Insurance, I split that into a string array:
sParams(0) = "All"
sParams(1) = "State"
sParams(2) = "Insurance"

Im working on a school project where i add items to a listbox in two columns. The first being the name of a course and the second being the credit hours of the course. I can add and remove the items just fine BUT when i remove an item im also required to subtract the credit hours of said item from a variable i have called "totalhours." Essentially im trying to figure out how to subtract a certain piece of a selected listbox item from my class level variable.

removing the last item in the listbox which is 9.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Label3.Text = ListBox1.Items.Count
[Code].....
As you can see, I set the Label3.Text = ListBox1.Items.Count and when Label3.Text = "9" I need help making it remove the 9th item.

I got this code but it won't work...
For Each item In ListBox1.Items
For i As Integer = 0 To ListView1.Items.Count - 1
If item.ToString = ListView1.Items(i).Text And ListView1.Items(i).SubItems(1).Text = TextBox4.Text Then
[code]....
It only deletes 1 listbox item while there are more items that have to be deleted.after debugging i get this:List that this enumerator is bound to has been modified. An enumerator can only be used if the list does not change.

i need to get ALL the words/items in the listbox to go INTO a textbox... i know how to do it the opposite way with lstbox1.items.add(txtbox1.text) - etc.... but it need to figure out how to make it go from LISTBOX to TEXTBOX. i've already tried stuff like "txtbox1.text = lstbox1.text" - that doesnt work, i've also tried "txtbox1.text = lstbox1.items", and just stuff like that, i've probably tried like 10 different things but none of them work im using VB 2008 Express Edition

Dim read As IO.StreamReader
read = IO.File.OpenText("C:2/kp.txt"[code].....
however when it is read into the listbox those 3 words appear on one line in listbox
How can i make it so that each line of the textfile is placed in each line on the listbox?

I have been working on a pythagorean theorem calculator and am actually stuck on the final bit of code. What I am trying to do is check the values (integers) inside a listbox, remove duplicate number (both values), and input one of the values into a textbox.
Here is an example of what I am doing:
LISTBOX VALUES
2
2
3
[code]....
When the program runs, check listbox value #1 and listbox value #2, if listbox value #1 and #2 match (2 & 2), input that value (not both duplicates) into a variable, remove both of the duplicate values, continue checking the rest of the values, and finally multiply the leftover values. I am sure that sounds confusing. Here is what the final output will look like
LISTBOX VALUES
3
7
[code]....

I want to remove items from a listbox 1 at a time. I have two timers set up to remove the two types of items that are put into the list box. When there is a "Player 1 killed Button 1" following a "Player 1 killed Button 2" or vise-versa they get removed at the same time. Is there any way to prevent this?
Code:
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim XP As Integer

I need to know if there is a way to remove any items from a listbox if they contain no text. Like if there are three items(Blah, ,Blah) listed in the listbox like so (remove the middle line that is empty so the listbox now contains two items(Blah, Blah) listed like so Or if there is a way to do this to a textbox that would work too. I'm working in VB 2010

So im trying to do a simple system in my VB Express Edition 2008 and what it does is add some car models (example) to a list box and stores it in a .txt file for future use. But when the user clicks a delete button it should delete from both the listbox and the .txt. I have to use only the FileOpen(OpenMode.Append or OpenMode.Input/Output) functions.

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.

Currently I have a textbox with some words and the program randomly removes five words and inserts 5 textboxes below the main textbox for the user to enter his or her answers. The goal of the program is to help the user memorize the text on the program. They can hit a button and new words can be removed and the original words will return. This is so that user is not entering the same answers over and over again.
What I've done is I have created a Listbox and I want the words that are removed to be listed in the Listbox so that the user will have a wordbank to use and I want it to work so that when the user hits the button for new words then the listbox will replace the old words with the new ones.

Basically, the user can type in a name and a job description into two different txt boxes and then click add. It then adds the name to the listbox and stores it in a string list (Public strList As New List(Of String)) it also stores the job description in a string list as well (Public strListDescription As New List(Of String))Then when you select an item in the list box it knows what data to bring up in the txt boxes using an array with these lists:
Code:
Private Sub lstMyCourt_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles lstMyCourt.SelectedIndexChanged
Dim i As Integer

How would I remove an item from the listbox.. I used the code below to populate using a class with description and value properties.
I cant use listbox.items.indexOf("listitem1") to get index
I cant use listbox.items.remove("listitem1")
If I use listitem.items.removeAt(1) it works of course. How can I get my index in this case?
'Users
Dim IAdapter2 As New ds_SecurityTableAdapters.Security_UsersTableAdapter
Dim usersDT As ds_Security.Security_UsersDataTable = Nothing
usersDT = IAdapter2.GetUsers()
Dim userItems As New List(Of myItem)
[Code] .....

I have to make a listbox with a few(8) names in it & double clicking on a name in the listbox will removed the name from it. I have already add the names into the form using the listbox.items.add method & would display the names in it. Then I enter the coding for 8 names in double_click procedure (listbox) using the "listbox.items.remove" method. However, when I try double clicking on a name in the listbox, it would remove all the names instead.

My knowledge of VB.net is limited (only have been reading from the book)
so what i need to do for my project is to populate a listbox with files from a certain directory (C:folder)
then once it's populated, i can select an item and it will open up in a rich text box.
This is what i have so far for the active directory > list box:
Dim di As New IO.DirectoryInfo("C:Documents and SettingsuserDesktopfolder")
Dim diar1 As IO.FileInfo() = di.GetFiles()
Dim dra As IO.FileInfo
[Code]....
