Listbox Items Count Check Failing

Feb 21, 2009

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]

IDE :: IntelliSense Shows () After Count Property For ListBox.Items?

Apr 21, 2009

I am a student in a Visual Basic class. We were working on a project using the Count property of the ListBox. I'm using Visual Studio Professional Edition 2008. When I enter a line in the editor that looks something like this: If lstResults.Items.Co

IntelliSense will generate a little balloon that says 'Public ReadOnly Property Count() I saw the () after Count and thought that meant that was the proper way to code it. So that is what I did. The code seems to work with ...Count() or just ...Count. I was wondering if there is some reason why the parens show up after the description of the Property in IntelliSense.

Check Number Of Items In Listbox?

Jan 17, 2009

I 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]...

VS 2005 Check Grid Items If Checked ListBox Items Checked?

Aug 21, 2009

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.

Private Sub CheckedListBox1_ItemCheck(ByVal sender As Object, ByVal e As System.Windows.Forms.ItemCheckEventArgs) Handles CheckedListBox1.ItemCheck

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.
