VS 2010 : Remembering The Listbox Items?
Mar 23, 2011
I've been working on a little project recently which is a music player (unoriginal I know, but I'm just learning ). Basically, I want the items that have been added into the listbox to be remembered for the next time the application is opened so that you don't have to re-add the items. The items show up like this (because they are added from my documents): C:UsersEthanDocumentsMusicCage The Elephant - Aint No Rest For the Wicked.mp3?

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.

I am using a listbox that is filled with a list of items from Database. When I am deleting an item from the listbox it is has to be deleted from Database, and that is all working fine.The problem is, even after deleting the item from the listbox, it is showing in the listbox, I have to close and restart the app to get the deleted item off from the listbox.
Is there any way to remove an item from listbox at the same time? I don't want to use timer to refresh is there any other way to refresh the listbox items???

I am making a program, and I have a listbox which will contain A big list of file Paths. I have two buttons Add and remove. Adding items is easy and I have done this. But removing items is the hard part because the listbox is multiselect. I have tried so many attempts It wouldn't be useful to post code. But the closest attempt is

I am wondering how i would go about taking multiple items (randomly) from a listbox and displaying them in a label!Now this listbox wouldn't have to be visible, maybe i can do it without it even being a listbox?I want to have 25 labels and each one recalls a random value from the list (doesnt matter about being unique and the list will contain about 20-30 items)Im just a bit stumped on how to do it as ive done some looking into it but most people are asking for randomized numbers or unique items where as i need randomized items from a list which aren't unique!

I have a listbox control on my form that has SelectionMode as MultiSimple so I can select more than one item with my mouse. I added a contextMenuStrip to my form and added it to my listbox. I'd like the user to be able to select a few items in the listbox and when they right click > Copy it would copy the contents of the selected items to the Clipboard.

I googled to find how I can change the items forecolor or backcolor. I want the items containing "Unmatched" to be one color and "Matched" another.

basically i had this problem before which i fixed with this code!
'REMOVE TIME
If ListBox1.SelectedIndex <> -1 Then
Dim Box As MsgBoxResult = MsgBox("Are you sure you want to remove this time?", MsgBoxStyle.YesNo)
[Code]....
It worked perfectly, all ive done to my code since is change the way the listboc is loaded / saved, it now comes from a .txt in My Documents rather than the C drive.
It now only deleted the top value of the group selected int he listbox and not all of them as it did before.

how to write the items in the right listbox to a .txt file using StreamWriter. I need the output line to resemble:
"set sv_mapRotation map mp_abandon map mp_afghan map mp_boneyard map mp_brecourt map mp_checkpoint map mp_complex map mp_crash" The order should be just like it is in the right listbox.
This is the code that I have set up to begin this:
myWriter.WriteLine("set sv_mapRotation" + " " + """" + """")

So I'm using the following code to add items into my list box, and I'm trying to get it to check the contents of the list box as well.
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
If ListBox2.Items.Contains(TextBox3.Text) Then
MsgBox("Character already exists!")
Else
ListBox2.Items.Add(New LBnfo With {.v4 = RadioButton6.Checked,
[Code] .....
But when I try to compare the two:
If ListBox2.Items.Contains(TextBox3.Text) Then
MsgBox("Character already exists!")
Else
It doesn't show the message box even when the character actually does exist. I believe the problem is that I never do add the item really. I just use, "Return Me.character," which is assigned the value of Textbox3. So I just need to figure out how to check Me.character before returning it.

How would one go about checking a listbox's items for duplicates? Basically I need to write a program that displays the teams from a text file provided by my instructor, in alphabetical order. I can do that, but what I can't figure out is how to prevent the For loop from adding a duplicate team. What I'm envisioning is:
If teams(i).name is not in lstTeams.Items Then
lstTeams.Items.Add(teams(i).name)
End If
I have a program that compiles and works so far, except for the above problem and my alphabetical order (which I can probably figure out on my own:
Public Class danbrockteams
Structure team
Dim name As String
[Code]....
This works except that my listbox is filled with the team every player is in rather than just listing all possible teams. Not exactly looking for someone to just give me the answer, as I understand things best when figuring them out on my own, so I suppose a hint is what I'm really after.

I have made a little application for me and my friend to be able to chat with eachother, but now we have some unclear strings as you can see on the image below:
I would like to change for example the username or time date to a color or make it bold, could anyone tell me how to change ONLY that and not everything? I'd love to have such a thing as it makes the whole application way 'clearer'.

I have a list of links and need to check some data in it.
i placed all the list in a listbox and each item is verified for some result
now i want to see how many items are processed and how many are still need to process
Example: in a label it must display total count of items and items completed and it must change once a item is finished.
over view of my code is:
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
For Each item In ListBox2.Items
[Code]....
Once an item is finished label must change the count.

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'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.).
