I don't think so, you can restrict access with macros but this can be
overcome by opening the workbook with macros disabled.
You can also write code to prevent a workbook being opened unless macros are
enabled, but this is overcome quite easily by anyone with a little knowledge
of Excel and VBA.
In short, Excel is not designed for security, protection etc is really only
to prevent accidental overwriting of formulas etc and maybe rudimentary
protection aimed at the novice,

Without using macros, is there a way to allow someone to view an
application only once or twice, after which point they could no longer view
the spreadsheet (for example, if I want to send a worksheet sample that I
don't want to be used permenantly).
