HELP! - how to set in spreadsheet to be used by only one user?

[sonar]

Hi

I dont want someone else to use my work, instead of password protect
it, I want to hardcode my friends company name in the "view code"
section, and if the name gets changed on the worksheets, it must auto
hide all sheets.
Or is there a much better way to do this?

regards

If you're really looking for security, your best bet is to stay with the
password (under File|SaveAs|tools).

Anything else would probably depend on macros and macros can be disabled.
