Forms :: Having Listbox'es And Their Items?
Aug 26, 2011
I have a listbox on my form, and a procedure that scans a certain directory for sub-directories, it then adds each subdirectory as a item in the listbox.
ex :
g:movies2010Clash of The Titans
g:movies2010Date Night
g:movies2010Red Dawn

I remember in the old VB6 that there was something simple as listbox.add("my string", 1 This '1' would meant the position I want it to be added, which means 'the top'I'm sure it sounds newbie... but hey, what a heck... I'm only been programming .net for a few months.

simple problem that i just cant figure out. here is the code
[Code]...
this code works fine as long as i dont remove ALL items, the error i am getting is index is out of bounds of the array, i have tried -1, -2 0 +1 +2 and all are still giving this error, i cant just create code for remove all as i wont always need all removed so i kinda of have to get this code or something similar to remove only checked items. the code below is code i have tried

I am trying to get the items out of a listbox and put into a text box .. I am putting the listbox items into an array and I keep getting this error: InvalidArgument=Value of '1' is not valid for 'index'. Parameter name: index
bolded code where this occurs here is my
Private Sub btn_BuildText_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn_BuildText.Click
Dim delimiter As String 'Holds the String character representing the chosen delimiter
Dim i As Integer 'Loop counter

I'm using the following to add a list from a txt into a listbox, which works perfectly.
Dim OFD As New OpenFileDialog
OFD.Filter = "Text Documents (*.txt)|*.txt"
OFD.Title = "Open List"
OFD.ShowDialog()
ListBox1.Items.AddRange(IO.File.ReadAllLines(OFD.FileName))
The similar thing below does not work to load sites from the clipboard. What else could I use.
ListBox1.Items.AddRange(IO.File.ReadAllLines(Clipb oard.GetText))

I am adding an object to a Listbox which has the properties "ID" and "Text". I have set the "DisplayMember" property of the Listbox to "Text" and "ValueMember" to "ID".Everything works fine when I add a new item to the list, but when I edit the item and change the "Text" value, it is changing in the object but the Listbox still just showes the original value.I have tried calling ".Refresh" and ".Update" to see if they worked, but made no difference.I usually use VB6 for prototyping programs but decided to use VB.NET for this one. Did not realise VB.NET got shot of the "ItemData" property in the ListBox control.

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 am making a virtual crafting application (similar to that done in Minecraft)
currently I have made a test "crafting recipe" which checks if the listbox (mixbox) has 1 window, 1 door and 1 wheel. the code looks like this:
If mixbox.Items.Contains("window") Then
If mixbox.Items.Contains("door") Then
If mixbox.Items.Contains("wheel") Then

I've looked everywhere on the internet for multiple items drag&drop between listboxes and found only examples showing single item drag. I know how to make a single item dragdrop operation between two listboxes using MouseDown, DoDragDrop, DragEnter, DragDrop Now what I'm looking forward to learn is the ability of dragging more than one item from one listbox and dropping them in another listbox

I am using Visual Basic 2010 Express. I have 2 forms. A main form which does all the grunt work and then a small supporting form to get some additional user inputs.
Some program background...I am developing a program to characterize solid rocket motors based on test stand data for a hobby project. I load the time, thrust data into lists via a streamreader from a text box.
However, since the data is raw I would like for the user to select the "start" and "end" of the burn. I am currently trying to do it right after I load the data. As I read the data in, I just put it in the listbox of the supporting form as well. My main issue is, I need two values from the user. A start and end time. the index would probably be easiest, as I will rewrite the data list based on the time increment and delete everything before the first listbox selection and everything after the second selection. I can't get the values from the main form. I have exhaustively searched the internet trying to find something that I can apply. If someone could help with a framework on how to do this.
I understand how to get text from this text box on a different form, but this deals in variables and maybe setting up a class? I am having trouble communicating between the two forms.

We have a button, textbox and a folder browser... We made it so that when you click the button it shows the folder browser dialog.. And you choose your folder/path, then it shows the selected path in textbox.. We are succesful on this.. But now weve added a listbox, And when you selected the path it will do this..

I was writing a program that would save the contents of a listbox to a database and wanted to reload the users' choices when the opened up that particular row again. My first thought was to do it with two for loops, just as I used to do in VB6, but I thought there must be a better way to do it. And there was. Sort of. It basically involves using the SelectedObjectCollection class.For this demo, you'll need a listbox called Listbox1. Set selection mode to something other than "One" or else it won't work as expected
Dim items(0 To 3) As String
items(0) = "One"
items(1) = "Two"

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 don't know what's wrong, i can only move the 1st item but the second and so on doesn't make any changes. It remains in a listbox.

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.).

We have an application that has a main form with a map on it. Right now the paradigm is to have forms that are displayed using menu items to display information to the user. Most of these forms are modal forms, but a couple are non-modal forms that interact with the map. For some of the forms, it really would make for a better user experience if we could dock them in the main form of the app and allow the user to see both the form and the map. For instance. We could have a list of map features in a docked window, and select one of the items on the list and have the map zoom to that feature. Or do the reverse: let the users select a map item and have a docked window that shows details of the feature. Sounds great, but I wonder about what sort of gotchas we may encounter. In particular, what if we have two windows docked at the same time? Could we get tangled up in our event code?

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
