ingI'm writing an Excel application in VBA and I'd like to be able to do the
following

1) Hide and deactivate the ribbon so the user of my app won't accidently do
something he/she shouldn't

2) Lock a specific window to a specific worksheet -e. g. make the user
unable to change worksheets within a window. Presumably this would involve
making the worksheet tabs at the bottom of a window dissappear.

How might I accomplish the 2 things mentioned above?
