I was able to remove the formula bar and the Grid headings with the following code. app.SetDisplayFormulaBar(FALSE); Window win = app.GetActiveWindow(); win.SetDisplayHeadings(FALSE); I still want to remove the "Formatting Toolbar" and all of the menus associated with Excel. Anyideas. Classes of interest are --> Menu, MenuBar, MenuBars, MenuItem, MenuItems, Menus, Toolbar, ToolbarButton, ToolbarButtons, Toolbars Sincerely, Mardigin
