Sub Example_AddSubMenu()
	' This example creates a new menu called TestMenu and inserts a submenu item
	' called NewFile. It then creates a menu item, called open,
	' on the submenu.

	' The menu is then displayed on the menu bar.
	' To remove the menu after execution of this macro, use the Customize Menu
	' option from the Tools menu.

	Dim currMenuGroup As acadMenuGroup
	Set currMenuGroup = ThisDrawing.Application.MenuGroups.Item(0)

	' Create the new menu
	Dim newMenu As AcadPopupMenu
	Set newMenu = currMenuGroup.Menus.Add("TestMenu")

	' Add the submenu
	Dim FileSubMenu As AcadPopupMenu
	Set FileSubMenu = newMenu.AddSubMenu("", "NewFile")


	' Add a menu item to the sub menu
	Dim newMenuItem As AcadPopupMenuItem
	Dim openMacro As String

	' Assign the macro string the VB equivalent of "ESC ESC _open "
	openMacro = Chr(3) & Chr(3) & Chr(95) & "open" & Chr(32)

	Set newMenuItem = FileSubMenu.AddMenuItem(newMenu.count + 1, "Open", openMacro)

	' Display the menu on the menu bar
	newMenu.InsertInMenuBar (ThisDrawing.Application.MenuBar.count + 1)
