Hello,
the above mentioned way describe the steps in the UI.
On the other side you can do the same with scripting. For example you can hide the 'Standard' and 'Formatting' toolbar with the following commands in the OnLoad event of the form.
var objCommandbars = Application.ActiveWindow.Commandbars;
objCommandbars("Standard").Enabled = false;
objCommandbars("Formatting").Enabled = false;
Hope this helps.
