I have code that i wish to run every time an item is highlighted in a listbox, or that highlighted item changs to a different item in the same list.
Atm, i am using 'Handles lbDiscoveredDevices2.SelectedIndexChanged' where lbDiscoveredDevices2 is my listbox. I dont think this is right as if i click any blank area in the list...it runs the code, and trys to refer to highlighted items, that arnt highlighted = error.
check if item is listbox is already selected (highlighted) vb.netbut this code not work
If listBox1.SelectedItem.ToString = listBox1.Items.Item Then
Return false ?

View 4 RepliesI have a listbox, textbox, and a button. every time I push the button, an item from the listbox is put into the textbox. when the button is pushed again, it grabs the next item in order and puts it into the textbox. so on and so on until it gets to the last item. once I get to the last item it keeps repeating the last item over and over again. SO what I was wondering is how do I get a messagebox or some sort of checker to tell me when it has moved the last item from my listbox to the textbox?? PS textbox2.text=0 and every time the button is pushed another number is added to the value of textbox2.text. so basically if I could figure out how to grab the value of lines at any given time in listbox I could call a msgbox up!! here is the code I am currently using[code]...
View 3 RepliesFirst how do I check if each listbox item in a listbox contains an expression (Regardless of how many items there are in the listbox) and secondly how would I replace that with text that I want
So, if the First item in the listbox contained "Http%$$" then how would I change that to "Http:" without affecting the rest of the text in the item
Here is the code I have so far

I don't know what is wrong with this code, but it is not detecting when there are no items in the listbox. It ALWAYS returns that there is something in the listbox, even when there is not and keeps erroring on the line of code in BOLD.[code]
View 1 RepliesWhy 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 I have Check items in a Listbox for a text that is = to Label/Textbox
I want to control a Counter I have

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 have a listbox List1 in Form2 and the items are populated to it from another form Form1. In form2 i have created a button named btnUP. When we click the btnUP then the highlighted selected item in the listbox moves one level up. this is working fine.
The problem is only the value is moving up but not the highlight.
i have also set the setselect property to true "List1.SetSelected(i - 1, True)" but no use ("List1.selectionmode = one" )
don know wat is wrong with the code.But it is not working
So here is my code
Private Sub btnUP_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnUP.Click
i = 0

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.

I have a list with a boolean value as one of the properties. I need to check if every one of these is true. Now normally LINQ would give a nice clean answer here, but as I am using .NET 2.0 I can't use that.If there a nicer way to do this or am I going to have to do a for each loop and break out on finding a false?
Edit:Seems I could have been a bit clearer. I have an object in a list (eg List (Of MyObject)). There is a boolean property on this object called Processed.I need to check that all objects in the list are processed.So in LINQ I'd do:if (from o in list where o.processed = false select o).count = 0 then....
