How To Retrieve All Items In ListBox With For Loop
Nov 25, 2009
I want to retrieve all the items in a listbox with a For loop. there are only two itemsin the listbox. I'm able to retrieve the first item in the listbox when the counter of the for loop is 0. when it gets to 1 an IndexOutOfRange Exception is generated.
Here is my code.
Dim i As Integer
Dim count As Integer=Me.ListBox1.Items.count
Dim sel As String
For i=0 To count-1
sel=Me.ListBox1.Items.item(i).ToString
MsgBox(sel)
Next i

I want to retrieve the selected items in a listbox, save them to a collection, and then use that collection later. I thought that was simple enough, but when I clear the selected items in the listbox, my collections (items, indices) change. I found this out by stepping through the code.
Basically what I'm wanting to do is move items in the listbox up or down (up in this case), and still keep them selected.

I have a quick question...is it possible to make a "for... each" loop that would go through each selected item of a listbox? What I want to do make sure there are no dupe names in the listbox.

I am binding my listbox to a dataTable, the reason why i am using a listbox is for multiple selection, the user can select more that 1 item, when the user has selected there items, i need to save them into the db, line after line. heres my code, i cannot get the listbox to display all the selected items in my test page.for now in my test page, i just want to show the selected indexes of the items, and then in my next step i would want to add then indexes to the database, for now i just want to loop and display all the selected indexes.

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.

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 datatable which has rows of product names. I have a table in SQL Server which has product details, with ProductID.I need to retrieve the ProductID for each product name. I can do this using a for each loop but this is way to slow. Is there a way to retrieve the relevant ProductIDs for the products with one transaction rather then using the for each loop?

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.).

I can't seem to find any answers that work. Here's the setup:
Info class: Public Class ProductStageInfo
[Code]...
maybe I just don't understand the whole collection/index/thing. All the examples I've found are regarding single dimension collections - 'how to find name within this collection', and the responses use strings to search through them, but somehow the Info class is being treated differently, and I'm not sure how to translate this..
