Clear Items From A ListBox?
Jun 20, 2012
I enter a name into a text box as well as a score (from 0-100) into a separate text-box then i press 'Add to array' and they go into the array BUT THE DON'T SHOW UP until i press "Show me the array.Once i press "show me the array" i get my names and scores in 2 separate parallel arrays (which is what i want)but now i need to assign a grade to each student (preferably next to each students score and name.I have no idea how to do this, possibly use Case-where or a series of 'If' statements?[code]...

I am using VB.NET (version 2008). I have two types of items populating in a listbox (checked listbox). For example: lets say one is type "A" and other is "Type B". Their names maybe same so if the user sees those items in listbox then he won;t be able to determine their type until he click on them and checks out its properties. I wanted that I add each item to listbox and colour them so that blue for example means type "A" is there and red means the other. So this way I will be able to know at a glance that how many item of what type is present. I guess it may not be possible to do that in a standard checkedlistbox. I am also using component factory's krypton controls which enhance the gui of an application. But I dunno if I can progress using that.

how to clear items from a ListView but no advice on how to clear columns from a ListView. The first time that the form is activated, coding creates and loads four columns in a ListView. On subsequent activations I want to remove those ListView columns before proceeding, otherwise I get eight columns and then twelve columns etc. There has to be a simple way of putting the ListView back to its initial state.

I have a list box which gets populated on the first run of the program by the user. On the next run it needs to be completely cleared so new values can be displayed.

I'd just like to know how to clear a listbox of its entire contents. I know in VB6 it was something along the line of 'lstBox.Clear', but that doesn't seem to be the case in this new version of VB.

So I want it to remove any text in the list box that has a "Job" in it and just replace it with a blank nothing.
Like if the listbox looked like this
Yardjob
jobsong
redjob
then it would change it to this
Yard
song
red
I also would like a way of removing any blank items from the listbox.

I have a small script that logs all of the website I visit and then displays them on a form. When I open the form the first time it displays all of the websites like it should. However, the second time I open it, it displays two of every website. The third time opening it, three of every website. I think that it is because the data doesn't get erased from the listbox when I close the form. Is there a way to clear the listbox when the form closes or do I need to find a new way to set it up?

I'm making an application that does some stuff involving the given subject, so this is very crucial to the completion and efficiency of my application.What I'm in need of today is simple (well, "seems" simple). I have one listbox that I want to populate with directories file's names. I don't mean the files inside the directories, but the names of the folders inside the directory.So, I have "c:empdog", I'd click on my button or whatever and search for the directory and I choose "temp", said listbox would show "dog".
UPDATE: Oh, BTW. It doesn't HAVE to be a listbox, it can be anything (IE: Textbox, Labels, Etc.).

Why is this code having the opposite effect? If It's checked in the checkedlistbox it's not check in my view, if it's not check in my checkedlistbox it is checked in the grid.
EDIT: More specifically. The CheckState.Checked is always the opposite. .Checked means it's not checked.
Private Sub CheckedListBox1_ItemCheck(ByVal sender As Object, ByVal e As System.Windows.Forms.ItemCheckEventArgs) Handles CheckedListBox1.ItemCheck

i have a list of items in a listbox and i want to move all of them into another listbox. I'm using a loop to do this but it always generates an exception anytime the loop's counter equals 2. Currently there are only three items in the former listbox. The first and last items are moved correctly except the second.[code]
