Preventing password removal tools from working.......How?

Has anyone seen a good way to prevent the thousands of password removal
tools from working?

I would simply like the Excel protection to NOT be easily defeated by
the use of these tools.

Any ideas?

The only way is to not let your workbook fall into the hands of people who will
try to break the password.

This may mean don't share it with anyone.

There isn't any such thing. Excel, indeed all of MSOffice, does
not have strong security. You should consider it to be protection
against accidental change, not against malicious individuals.
Professor Moriarity is not even going to have to slow down to
get your data out of any Office product.

If you need strong security, you need some other product.
If you have data that would cause great harm if it was hacked,
then you should not be storing it in accessible MSOffice files.
So such things as medical records or credit card numbers
should be behind something stronger than MSOffice security.

The easy way is to make it so that only trusted persons can
get the files. Say, put it on a LAN that has no connection to
the outside world, then only let people on that LAN that
are supposed to have the data. Even then, it's only as good
as the people. If they let strangers snoop through the LAN,
or take the data home, or bring malicious software in on
floppies or such, it can still be very bad.

Does SumIf work with a range?
I thought you could Sumif on a whole range, ie if A1 to A10 was your criteria range, and B1 to D10 was the range from which to sumif. However it only seems to sum what is in B1 to B10. Is that right?

Removing wire frame in 3D surface chart.
I'm am experiencing difficulty to view 3D surface chart as the number of data points are increased due to the wire frames in the chart. Is there any way to remove wire frame in a 3D chart?

The quickest way to do this is to click the legend, then click the legend marker for the first entry. Double click and set the border to none. After the dialog is closed use the left arrow key to move to the next entry. Press F4 to apply changes to the series. repeat for all entries. C...

How to Prevent Users From Seeing Activities Based on Regarding
In the interest of leveraging CRM to handle more of our internal operations, I've added some custom entities to the system to track marketing events. Because these marketing events have financial information associated with them related to the cost of the event, I don't want anyone in the support department to see this information. I can easily prevent them from seeing the entities themselves, but they can apparently see all of the activities related to the entity. Because some of the e-mails related to the entity contain financial information, this is unacceptable. Does anyo...

Conditional formatting not working as expected (A2007)
I've got 4 unbound textboxes which represent start date, start time, end date, end time. These textboxes are visible and initially get filled in with data from two bound fields (Start_Time, and End_Time) which are hidden on the form. I did this so the dates are separate from the times allowing use of the date picker for the dates and a spinner button for the times. As each of the unbound fields is updated, the appropriate bound field gets updated as well. I've setup a conditional format on each of the unbound fields which is set to evaluate the expression ([Start_Ti...
