I am adding values and descriptions manually to a list box.I have a class for the items [code] and in a form the most basic example click a button to add a value and some text and then show a messagebox to get the value [code]however ListBox1.SelectedValue is always blank , however no error is thrown when adding the values.I have gone right back to basics with this example , but just cannot get a value added in manually and stored in the listbox.value property.
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.
As the title describes I tried to get the selected items and it returned an emtpy collection. The property only works once after that something goes wrong and it returns an emtpy collection. Does anyone know why? Or knows what I'm doing wrong?
Is it possible to pause the music then if I resume the music it will just continue the flow? I mean if I pause the background music in 33 seconds and the music has 50 seconds and I resume it will just continue playing in 33,34,35 etc.. seconds?
I was wondering if their was a way to for me to turn off events and then turn them back on in my program or just queue them up until i am ready for them to be excuted. Kinda like how a OS turns on and off interupts. Is this one of those general programming no-nos?
I am using the below code to find all the items in a listbox using vb.net 2005. But how can remove the non searched items from the listbox after searching?

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.).
my homework question is to display the selected items from a listbox (multi-extended) in a label. I need to display all the selected names in a label. the simplest most uncluttered way of doing this. This is what I've got but it doesn't work.
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.

How can you add items to a listbox on a form? Also this needs to be included so if another item is added by user it will be added directly to database.
Reason i am asking that is my project has to work in cojunction with Oracle Plus.
So far if i remember it is something like
.Add("Horror") .Add("Romance")
I'm unsure if that is correct but i want the items to appear so the user can select one from list.
I think you have to include a data reader but don't mind that i can handle that. All i want is to add items to listbox when form loads.
