The best way is probably to include it, but use VB protection not just
workbook protection.
Have a userform pop up everytime they open it if they have not entered a
password, something like

Dim showForm as Boolean

showForm=True

on load event
If showForm=True then
form1.show
end if

Then you can either put a counter that increments everytime they click the
ok button without putting in the code, once it hits a limit it will no
longer
be enabled without the code, or set the button to disable if there is no
valid code.

on form load

If myCounter3 then form1.commandbutton1.enabled=false

on for button click

If form1.textbox1.text <"Password" then
myCounter=myCounter+1
end if


hope that gets you started

Is it possible to store a module (maybe export it and keep it in a
specific
location), then 'call' it from the workbook. So it would be like having a
text file in a folder on your c drive and then instgructing the code to
copy
the string and use it as a string variable in the code and run it from
within another sub.

e.g.

Sub GetOutsideCode

Dim sCode As String

sCode = TextFileInSpecifiedFolder.Contents

Call sCode

End sub


or some such thing. I know it used to be possible to get values from a
closed workbook using GetValue with excel 2003, don't know if it's still
available in 2007 (anyone know?) but it strikes me that if it is and my
idea
above won't work, then storing the code in cells in a workbook should
produce the same end result.

One of my reasons for wanting to do this is that in order to protect
intellectual property in an excel workbook it could be possible to have
the
file containing the code in the specified folder and then kill it at a
specified interval unless a passwrod was entered before that interval.
Bit
of a whacky idea maybe but it should work well enough for the audience i
have in mind.

Thanks and regards, Mark
