Hi guys i need really help cuz i'm new and still learning vb.net programming.
I think you do not need ask me what i need exactly cuz all says title.
I hope someone will know how to solve this problem for my project which i can't find out how to fix the problem i have only this small peace of code which does a bit of my work but do not hightlight items as i type from textbox.

Here is:

This one find extact items in listbox when i type but it does not hightlight them only add to listbox1 items extact as it found.

While ListBox1.FindStringExact(TextBox1.Text) <> -1
ListBox1.Items.Remove("")
End While

And this one find extact items as i type from textbox but do not hightlight them too.

For Each Itm As String In ListBox1.Items
If Itm.Contains(TextBox1.Text) Then
ListBox2.Items.Add(Itm)
End If
Next

how do i fix this problem and hightlight all matching found items in listbox as i type from textbox ?
Thanks.

It depends on a bajillion things. Where are these chunks of code found? What's running them? What does "highlight" mean? Where's the focus... set back color.. etc?

ListBox1.FindStringExact returns a value, which you never use except to decide whether to keep searching the ListBox.
ListBox1.Items.Remove("") will remove blank lines from the ListBox. If you want to use Remove, and to remove all instances of the string you found, youcould change to the following:

    Private Sub TextBox1_TextChanged(sender As System.Object, e As System.EventArgs) Handles TextBox1.TextChanged
        Dim idx As Integer = ListBox1.FindStringExact(TextBox1.Text)
        While idx > -1
            ListBox1.Items.Remove(TextBox1.Text)
            idx = ListBox1.FindStringExact(TextBox1.Text)
        End While
    End Sub

How do you want to highlight them? It looks like you are only trying to add them to ListBox 2.

No i do not wanna remove anything just highlight words live as i type like so and add to listbox.
If it is possible.

Ok i found out how to highlight but now i have another problem with copy multiple selected items from listbox.

Can you fix it ?

Cuz it selects to clipboard only one item not all selected.

Here is the code.

Clipboard.SetText(ListBox1.SelectedItem.ToString(), TextDataFormat.Text)

And this one copy too only one item and save to txt to c:\ drive

Dim w As New IO.StreamWriter("c:\cool.txt", True)
w.WriteLine(ListBox1.SelectedItem, True)
w.Close()

how can i copy just selected items ?

You'll have to use ListBoxSelectedItems, and iterate through the collection (notice the difference SelectedItem vs SelectedItems).

Are you fixated on using a ListBox? If you could use a RichTextBox, it becomes quite easy to highlight any text at all.
