Answer 1

Have you tried protecting the workbook ? Two ways to do the same

1.) manually

2.) programatically

Answer 2

Following code should intercept Ctrl+V and effectively disable it

1.To disable the Paste Option(ctrl + v )

Application.OnKey("^v", "");

2.To enable the Paste Option(ctrl + v ) again

Application.OnKey("^v", Type.Missing);
