VS 2010 - Adding Items And Checking Contents In ListBox

Sep 25, 2011

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.

VS 2010 Checking Listbox Items For Duplicate Before Adding New Item?

Sep 8, 2011

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.

VS 2008 Adding Items In Listbox?

Aug 11, 2010

I am currently working on some tools and I am having some troubles adding new lines in a listbox.

vb.net
For i = 0 To lstFiles.Items.Count - 1
Process.Start("C:UT2004Systemucc.exe", "compress " & lstFiles.Items.Item(i))
If IO.File.Exists(lstFiles.Items.Item(i) & ".uz2") Then

[Code].....

The meaning of this code is that if the file exists, it will add a new line called Success below the dragged fileline. If the file doesn't exist it will create a new line called Fail below the dragged fileline.

Listbox Items Colour - Two Types Of Items Populating In A Listbox (checked Listbox)

Apr 28, 2009

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.

VS 2010 ListBox Items Refresh?

Aug 5, 2010

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???
