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.

I have a small program that talks to a server, grabs the content from a website using a php webscraping program and then places the results in a listbox as a string. My problem is taking this string and creating a list from it. Each item in the string is followed by a | (pipe). I have included the code that I've tried below:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim str As String

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.

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.

Directory Items TO Listbox Items?

Mar 17, 2009

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.

Adding Items From List Box

Jan 28, 2010

I'm learning how to add items from a list box to a combo box. I'm trying to follow what's going on in the function loop and comparing a boolean and selected index. I can see that it's comparing the item chosen to each item already in the combo box to make sure that it's not already there. If function finds that it's not in the list it sends back that it is true that the item is not in the list.

It then continues to the statement that adds item to the list. The code for the double click event is working fine and items are getting added to combo box. However, the code for the add button isn't functional. I'm not seeing why it doesn't work? I coded out the original code, and replaced with something I thought might work but it still isn't functional. [Code]

Adding Items To A Combobox?

Nov 27, 2007

In VB.Net for an ASP project I was able to do the following:

Dim Item As ListItem While DataReader.Read Item = New ListItem Item.Text = DataReader.Item("CustomerName").ToString Item.Value = DataReader.Item("CustomerNumber").ToString Me.lstCustomers.Items.Add(Item) End While

However in a VB.Net Windows Project it won't let me duplicate this.

I need to display the CustomerName but return the CustomerNumber of the selected customer

I am also adding the items in code because they are changing based on changing values.
