The assignment requires that you have two Forms. Here is a snapshot of the running program, with the 2nd form invoked by the main form. One is the main application form (shown here on the menus.html page), the other is a dialog box that is invoked when you choose the Border menu, Width command from your custom made menu user interface.
The dialog box of the Project menu, Properties command is used to set the Startup Object, in Visual Basic. If you have multiple forms, which one will automatically Show itself when you Run the application?
