But it dont work ?!!
I looked for in the web a way but i failed every time!
So i Ask here some help🥺 !
Thank you in advance for your answer!❤️

"it won't work" could mean any number of things. You need to actually explain the issue in detail, including what actually happens. If there's an error message, tell us what it is. The code you have would work under certain circumstances and not others, but you've not bothered to tell us what the actual circumstances are here. Most importantly, how EXACTLY was the ListBox populated in the first place and what EXACTLY do you expect to happen. You know, the information relevant to the issue. We could guess at a solution and we might even guess right, but we might also guess wrong. Just don't make us guess at all.

means you have option strict = off else it gives to you an error ("implicit conversion from object to string") so you should write :

Code:

---

Textbox4.text= listbox1.items(1).tostring

---

second, do you have at least 2 items in your listbox ?

That may or may not work, depending on how the list was populated and what the items actually are. If it was bound to a DataTable then that won't be all that useful.

i have at least one item but this item(s) are names in a simple list.

after, i have to try this :

Code:

---

TextBox4.Text = ListBox1.GetItemText(ListBox1.Items(1))

---

edit: this code above doesn't work!

option strict = off , must i change on ON! this setting is important?

We need the description of the error to know exactly what happens not just "it doesn't work".

yes you should put option strict = on, that will force you to write correct code and do the correct conversions yourself and not expecting the machine to do it for you.
If you have only one item

Code:

---

Textbox4.text= listbox1.items(1).tostring

---

will generate an error as the list start at 0

The ListBox's Text property (documentation) may be what you're wanting, though admittedly I am making several assumptions.

Try using the following code:

Code:

---

TextBox4.Text = ListBox1.Text

---

Does this provide you with the expected result?

Also, I wanted to mention that if you want to keep your code formatted then please use the [CODE] BB tag. There is more information in my signature on code tags.

i would like to write one item from listbox to textbox .
example: if the listbox.item(1) = franck the textox.text = "frank"
or if the listbox.item(5) = Sarah the textox.text = "Sarah"
it looks simple but in real, it is a bit hard!
i am trying to uest this by Delaney:
Textbox4.text= listbox1.items(1).tostring
wait and see...

I don't think you took any of my advice ranging from using the Text property to proper forum etiquette by using code tags. If you cannot follow those simple instructions then I apologize, but I must remove myself from this thread.

Yes i Saw it ! Don't worry! I am working now! I can't test every answer !👍thank you for your help! I will glance later!👍❤️

so if I understand well, you have a listbox with names. When you select a name in the listbox, you want to show it in a textbox, right ?

Create a new project with a form, a texbox and a listbox

Code:

---

Public Class Form1

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim list_name As New List(Of String) From {"Pierre", "Paul", "Jaques"} 'just a way to create the list of name, there are plenty other way
        ListBox1.DataSource = list_name 'bind the list to the listbox
    End Sub


    Private Sub ListBox1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged
        Dim lb As ListBox = DirectCast(sender, ListBox)
     
        If lb.SelectedIndex > -1 Then
            TextBox1.Text = lb.Items(lb.SelectedIndex).ToString
        End If
    End Sub
End Class

                Dim lb As ListBox = DirectCast(sender, ListBox)
     
        If lb.SelectedIndex > -1 Then
            TextBox1.Text = lb.Items(lb.SelectedIndex).ToString
        End If

THANK YOU very much! i see what i must do hence my code is inside a "timer". So, the question is "what term must i move out "lb.selecteindex" to have the same result? the listbox1_selectedindex is useless in my case(the index is not unknown).i suggest to put :
Dim lb As ListBox = DirectCast(sender, ListBox)

If lb.SelectedIndex > -1 Then
TextBox1.Text = lb.Items(listbox1.items(0)).ToString
End If

other try:

Dim t As Integer
Dim name(t) As String

For t = 1 To t = 13
name(t) = ListBox7.Items(t)
Next
TextBox1.Text = name(0)

i thank you again! we advance quickly!
