Sub Example_HelpString()
	' This example creates a new toolbar called "TestToolbar" and inserts a
	' button into it. The HelpString property of the toolbar is then
	' read and changed.
	' To remove the toolbar 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 toolbar
	Dim newToolBar As AcadToolbar
	Set newToolBar = currMenuGroup.Toolbars.Add("TestToolbar")

	' Add a button to the new toolbar.
	Dim newButton1 As AcadToolbarItem
	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 newButton1 = newToolBar.AddToolbarButton("", "NewButton1", "Open a file.", openMacro)

	' Display the toolbar
	newToolBar.Visible = True

	' Read the current value of the Help string
	MsgBox "The current HelpString for the toolbar button is: " & newButton1.HelpString

	' Change the value of the Help string
	newButton1.HelpString = "Use this toolbar button to Open a file."

	' Read the new value of the Help string
	MsgBox "The new HelpString for the toolbar button is: " & newButton1.HelpString
