The List Manager Project: Inserting

After creating the menu, we will add the listbox and write the code to insert items in the listbox.

Code

Private Sub InsertToolStripMenuItem_Click(sender As System.Object, e As System.EventArgs) Handles InsertToolStripMenuItem.Click
   Dim s As String
   s = InputBox("Enter item", "Add Item")
   If s <> "" Then
      ListBox1.Items.Add(s)
   End If
End Sub

See the complete code at this point.
