So I have three listboxes, LB1 is an uploaded list, LB2 is a master list, and LB3 is generated from LB1 items that are NOT in LB2. I have a button that replaces the selected item from LB1 with the selected item from LB2, woot.Since LB3 is a subset of LB1, I want to be able to select the items from LB2 and LB3 and have it replace the item from LB1 but running into some trouble with finding the appropriate item without selecting it. [code]
highlight Fred from LB1 and Freddy from LB2, click and Fred becomes Freddy in LB1. I want this same change to happen but by selecting the "Fred" located in LB3 (If LB1 is hundreds of names long, I don't want to have to sift through it and only make the changes that need to be made). [code]

I am trying to search through listview in VB.net 2008. It works fine with small list, but when the list is big ( around 25000 rows), if I search multiple items , it fails saying that index is not valid. Obviously what I understand is , it it tryiong to remove an index does not exist. But I am unable to figure out where exactly it is going wrong.
PS : while it is doing search through the entire listview, I am incrementing index = index+5 becasue I want the next 5 rows to be in the selection state as well.This is the code Private Sub TextBox1_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyUp If (e.KeyCode = Keys.PageDown) Then

I was generously guided by the community to use LINQ to find duplicates on my listboxes the last time around. However, I am now in a tough spot because I need to find and remove duplicates from a multicolumn list view. I tried using LINQ but it says that the listview object is not "queryable". Is there a way for me to find and remove duplicates using only one column of the listview? [code]The code now runs fine when I call it. But it does not remove the duplicates:

I have a Listview that will display all System Services on the local machine. I also have settings to change states of the services as a group as well as single selected item. My question is, Is there any way when the user selects which option to change, to highlight all the services that were changed in the listview, making it easier to see what the user has changed .

I have a ListView of 4 columns, one of which is a monetary value.I am trying to add these values of 'selected' rows. I can add ALL row's values - but not selected rows. The code that I use actually highlights all the rows that contain the string that is looked for but the result is not correct. Let me explain: Say I am looking for all the rows that contain the word "Special" and that it is in 4 rows. The 4 rows are highlighted but the result is the value of the first row highlighted multiplied by the number highlighted. In a Console.WriteLine I find that the same numberRow is shown 4 times. I can't work out how to get each row's value.[code]

I know that the "SelectedItems" in a ListView are a collection of items and therefore can not be converted staight away for instance into a string. How does one go about selecting just one of the items in the list view?My list view contains 3 columns/items: First, Last and EMPID. When the user selects a row in the listview, I need to pull out the EMPID item as a string variable.

I have this script which is designed to loop through all of the selected listview items, and delete them from the ftp server. - The list view item names are exactly the same name as they are on the FTP server.
For i As Integer = 0 To ListView1.Items.Count - 1
Dim ftp As New FTPclient(host.Text, username.Text, password.Text)
ftp.FtpDelete(ListView1.SelectedItems(i).Text)
Next
Some info:
The FTP server works fine! I'm using it in other places in my script, and those functions work fine. ftp.FtpDelete works fine as a function, I've used it to delete single files before. It doesn't delete any of the files, it just gives me a load of exceptions.

I have a multiline textbox in which i add values to.A button is pressed to put these values in a listview in the first column.I then have 5 or 6 other comboboxes and textboxes that will send information as subitems to the listview, only if the original item in the listview has a checked box. The code i currently have is just adding the subitems to however many checkboxes are checked.I am trying to get the subitems to add to all of the items that have checked boxes rather than creating there own rown underneath the checked boxes.[code]

I have a Form with listview of customer name. e.g. AAA, BBB, CCC, DDD, EEE. etc And 3 textboxes.
I want to be able to populate the textboxes when the user selects a customer. For example: If User selects AAA, textbox1.text = AAA, then if User selects CCC, textbox2.text = CCC etc.
I tired: (in a button on click event)
TextBox1.Text = Listview1.SelectedItems(0).Text
TextBox2.Text = Listview1.SelectedItems(1).Text
TextBox3.Text = Listview1.SelectedItems(2).Text
But this only works if the user selects 'all' 3 customers at once. I want to allow the User to populate each textboxes depending on how many they select eg. 'Upto' 3 customers .

I'm a student and I have a small project to create for my VB class. For the personal touch, I tried using a ListView to manage a SQL database (on a remote web server).What I need to do right now is determine how many items are selected (if more than one, enable delete and edit buttons, if more than one, disable edit button). I searched a lot for that, but didn't find anything working with me.Do you know a simple way I could get the number of items that are selected in my ListView?

I have a listview with two columns of data in it. I want to capture all the items in the listview into an array. The array will have two dimensions, one for column 1 and the other dimension for column 2. I am a little lost on how to iterate over the listview items. I figure it would be a for each statement. Its also the actual call that passes the found item and sub item to the array I am struggling with.

In my Windows Form I have a ComboBox that is filled by a Stored Procedure with a list of names. I have the Combobox set for AutoComplete to "Suggest" and From "ListItems". When a user starts to type in and the AutoComplete does not find any matches in the listitems the user can tab out of the ComboBox and leave what they typed in the combobox even though it is not one of the Valid Items. Is there a way to check the Comboxbox to make sure of of the selected Items has been selected?

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.
