Delete SelectedItem in Listbox from Folder and Listbox

Question

Please, I am intending to delete Listbox item i.e. delete selected item from both folder and Listbox. Implementing the following code, the file was deleted accordingly, but i got a conflicting error with a previous line of code, which terminated the application. Please, see attachment to view error. Thank you.

If ListBox1.SelectedIndex <> -1 Then  
     System.IO.File.Delete(ListBox1.Items(ListBox1.SelectedIndex).fullname())  
     ListBox1.Items.RemoveAt(ListBox1.SelectedIndex)  
End If  

Answer 1

Try adding the next lines to beginning of ListBox1_SelectedIndexChanged:

if ListBox1.SelectedItem Is Nothing Then 
   Return
End If

Before Return, you can also change or clear the labels and other controls according to your needs.
