The document discusses various ways to manipulate items in a ListBox control in Visual Basic. It describes code for: 1) Removing the text from TextBox1 from the ListBox1 items using a button click event 2) Clearing all items from ListBox1 using a separate button 3) Removing the currently selected ListBox1 item when the selection changes 4) Copying the selected ListBox1 item text to TextBox2 on regular click 5) Removing the selected ListBox1 item on double click.
