I have a listbox with several items in the list. I would like to bind the selected list item to a field in a table. How do I do this?
View 7 RepliesWhat I have is a listbox and a text box. I want to be able to select the items in the listbox (selection mode is set to multiextended). The problem is
Dim path As String = ListBox2.SelectedItem & " " & ListBox1.SelectedItem & ".txt"
'the line above creates a path with the title of an item from listbox2 + listbox1 and adds the .txt extension.
For Each item In ListBox3.SelectedItems
TextBox1.Text = item
Next
'this just makes it do nothing.
I have also tried diffrent methods to export an item title to a text file. for example I tried:
Dim path As String = ListBox2.SelectedItem & " " & ListBox1.SelectedItem & ".txt"
For Each item In ListBox3.SelectedItems
File.CreateText(path)
Next
'this just gives me a IO exception
It does create a file but it does not contain anything.
Mi'm working with a list box usually when i want to get the selected items i write something like this

it seems that the item is the datarow and i can not get the actual selected items

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

I want to transfer multiple items selected from a listbox to an access 2007 database using a parameterized query.When I select certain items from the listbox, only first item selected gets stored in the database.Other values selected are not written to the database.My code is as follows.Is my approach towards transferring multiple values correct?Someone
[Code]...
I have a listbox populated with items which are the numbers 0-10. I need to know how to make the app transfer the selected items into 3 separate text boxes. First it should total the the cumulative values of the selected numbers & place that value into the 1st box. Then is should list the total number of items selected from the listbox & place that number into the 2nd box. And finally it should give me an average of the selected items, now this part I've got down, as I can input the first 2 numbers manually into the boxes & will get a correct response in the 3rd text box.
Here's what I have thus far on my code,
Public Class Form1
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

I am making some kind of calendar where I can add tasks, so I can easily organise my tasks. For it to complete, I have 3 things I can't figure out how to do it:
1. When I launch the program, I want the items in my listbox to be sorted alphabeticly.
2. I want to save the items in the listbox, so if I close the program and reopen it the items are still saved in the listbox.
3. The items in the listbox all start with a date, fe. "13-4" for today. If that date already passed I want that item to be deleted.
Is it possible to change the text format of a ListBox selected item at run time?
View 14 RepliesI 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.
