customize users ribbon (like in excel options) upon open/activation

[GeneralDisarray]

Hello,



I know I can customize my ribbon through the excel options, but how to I do it programatically? I was hoping to find some code to add to the workbook_open, workbook_activation events to do the following:

Upon open or activation the workbook - hide all the usual Excel ribbon areas and show only the special one that was made for said workbook.

Upon close or deactivation of this same workbook - let the ribbon return to the normal state.

Thank you
