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.

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"

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 have a datagridview binded to a list of objects... I have a column named Selected containing a checkbox. When these checkboxes are checked and a button is clicked, I want those particular rows to be removed. I initially set it out to iterate through the grid's rows and RemoveAt(SelectedRowIndex) but of course when it removes an object from the List of objects at the selected row (IE Row 1, 4 and 6), the list indexes change and it fails to work properly when it goes to remove the next row since Row 4 is now row 3 in the list...? What is the best way to do this?
View 4 RepliesIs 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.

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.
