Protection has four sub menus
as detailed below

Protect Sheet...
Protection of data on
worksheets is a two-stage process in Excel. The
first part takes place under the menu option
Format>Cells...>Protection, where the cells
that you wish to remain editable are 'unlocked'.
You then take this menu option to protect those
cells that are still 'locked'. (Cells are
'locked' by default). In Excel 2003 and XP you
have a huge amount more control of what users
can/can't do on protected sheets, such as apply
autofilters, format cells, delete entire
columns/rows, etc. You vcan also go to the other
extreme of not even allowing selection! Of
course, as well, you have the usual ability to
set a password, (remember worksheet and for that
matter workbook passwords in Excel are very easy
to break with many free crackers on the
internet). Selecting this option fires the
dialog below.

Allow
Users to Edit Ranges.....
This is a new setting in
Excel 2003 which allows very fine control over
who can edit certain ranges within a workbook.
Clucking on the menu gives the dialog below.

In this you can add certain
ranges, whena sheet is protected into
which users require a password to edit, so you
could protect the entire sheet, but allow
certain users, by password to edit certain
cells. Here we have a range called 'Range1' set
up to cover $A$1:$A$11 (Obviously on the sheet
that is protected). If we click on 'New...', you
get the dialog below allowing you to set up the
range and a password.

Pressing the 'Permissions...'
button allows even more complexity and 'tuning'
by specifying the users who are allowed to edit
the range. You receive the dialog below, which
has a sub-dialog under the Add... button,
to search for and select certain users/groups.

Checking the 'paste
permissions information into a new workbook'
option in the top dialog, allows you to transfer
all the data of users and the various
permissions to a new workbook for record
purposes, like so:

Protect
Workbook...
Has a dialog as below and
enable you to protect the workbook 'structure',
that is users cannot move or hide sheets, unhide
them, etc. and protect the workbook 'windows'
meaning the workbook will open with the window
size and position exactly as you set, they
cannot be moved. A password is provide to
stop users from changing these settings.

Protect
and Share Workbook...
This setting not only allows
the workbook to be shared between users, you can
also track the changes made in the workbook. The
first dialog, below, allows you to set up the
sharing, with change tracking and a password to
prevent users switching sharing or any of the
other options back off/on.

After confirming the
password, you will be asked to save the file to
a new name/location to make it a 'share'. The
file can now be opened and edited by multiple
users at one time. |
