title: Disable copy/cut button on Office 2010 ribbon and prevent it from being changed
body: <p>I want to disable copy/cut button on Excel ribbon for a certain workbook, so that when the workbook is shared with others, they cannot use these two buttons. </p>
  
  <p>We can edit CustomUI.xml to disable the buttons, which is easy. However, people who have access to this workbook are also able to edit the xml file to get the buttons enabled. This is unwanted.</p>
  
  <p>I can protect the VB Editor of Excel workbook with password. Therefore, if VB can have control over the ribbon, that would be good. However, I did not find a way to do that.</p>
  
  <p>Is there any way for VB to check whether the buttons are disabled? If users (people who have access to this workbook) enabled the buttons by editing the xml, VB will detect that and hide the sheets, and show a warning message etc.</p>
  
  <p>(I use VB to disable ctrl+c, ctrl+x as well, so that users cannot copy and cut)</p>
