Hello! I can see two problems on the line that throws an error. - you don't say which TabPage gets a new control. (=> TabControl.TabPages(index).Controls.Add();) - you don't say which control you add to your TabPage (=> TabControl.TabPages(index).Controls.Add(something)) Maybe your code here isn't what you have in your application, but right now these two strike me as quite easy to correct.
